Tray dryers for drying wet, sticky or granulated products :

A range of technologies are used for food drying which include tray and tunnel dryers, spray, roller and freeze dryers. Tray dryers are quite suitable for drying wet chemicals, powders and crude drugs.

A simple tray dryer is a box-shaped cabinet in which a series of trays are inserted on shelves one on top of the other. Unlike an oven which perhaps has a heater in the base of the cabinet or walls, heat is supplied to a tray dryer by circulating air that has been heated either electrically or by some other means. One or more fans circulate the hot air over the trays.

The best tray dryers are those in which the air flow to the trays can be controlled. The materials to be dried are spread out on top of the trays which may be lined with paper. To shorten cleaning time and prevent contamination, disposable papers are used as tray liners. The trays are often supported on tiers made of wire mesh or perforated steel.

In the latest tray dryers, uniform temperature is achieved throughout a well-insulated cabinet by the use of strategically placed deflectors, which direct the air from one tray to pass over the tray above in the opposite direction. Air flowing in alternate directions over the trays ensures uniformity of flow and helps to keep the temperature uniform. The air may also be reheated before it passes from one shelf to the next. Air that passes each shelf loses a certain amount of heat (the latent heat of vaporization of the water that is expelled from the solid material).

Hot air therefore continuously circulates in a tray dryer, and the heat of the air removes the moisture from the material in the trays by forced convection. At the same time, moist air is expelled from the cabinet to vent.

Drying is commonly used after wet granulation. This is the process in which a tablet mix is turned in to a paste with water and then broken up in to granules. Granulation can increase the consistency and the flow ability of material in the tableting process.

Construction of a tray dryer :
There are several variants of tray dryer, ranging from simple manual systems ideal for batch processes through semi-automatic and automatic systems for processing large quantities.

The basic principles are the same in each case, as follows.
• The dryer consists of a heated box-shaped cabinet into which a number of trays can be loaded. The trays are rectangular or square in shape, typically between 1.2 and 2.4 m2 in area and up to 100 mm deep.
• A minimum of 3 trays can be often seen used in laboratory dryers; however industrial sized equipment may have up to 20 trays.
• The distance between trays and the material being loaded should be 40mm.
• Depending on the design of the dryer, several trays may be stacked on a ‘truck’ or trolley that provides the right separation between trays and which can be rolled in and out of the dryer. Alternatively trays can be inserted manually into runners in the dryer one at a time.
• Directional vanes are located inside the dryer to direct the air to circulate through the trays. In one design, the hot air passes over the bottom tray first, before passing over the second, and so on up to the top of the cabinet. In simple designs, the lower trays can therefore dry out first.

How it Works :
• Trays with wet solid materials are placed in the chamber.
• Fresh air is provided through the inlet and passes through the heater to be heated.
• The hot air is circulated by fans (typically at a rate of 3 to 5 m3/second).
• A turbulent flow or air can lower the vapour pressure of water in the air and reduce the air boundary layer thickness, thereby enhancing the drying effect of the hot air.
• Water diffuses from the interior of the porous material and evaporates from the surface of the solid matter.
• As the contact time is short (air flow rate is large), the amount of water evaporated in one pass through of air is relatively small.
• Some 80-90% of the air that has absorbed moisture from the material is recirculated to the inlet of the fans to mix with fresh dry air. Additional moisture is taken up by the air in the second and subsequent passes of air over the material.
• The moisture collected in the air is discharged through the outlet of the dryer. The high and uniform air flow ensures that there is a constant temperature within the dryer. These features help to achieve uniform drying of the solid matter.
• For wet granules such as tablets or capsules, the desired moisture content may be estimated by measuring the water that is discharged through the air outlet.
• The drying trays are then pulled out of the chamber and taken to the dump station.

Applications :
• Used for drying sticky materials
• Can be used for drying of crystalline or granular material
• Wet mass, paste, powders, and chemicals can all be dried
• A variety of small equipment may also be dried in tray dryers

Advantages :
• Loading and unloading of materials can be done without any losses.
• Batch drying is widely used by pharmaceutical companies.
• Each batch is treated as separate entity.
• Batch size can be small e.g., 250 kg or less per batch (pharmaceutical) and 1000 kg (chemical).
• Valuable products can be handled efficiently without loss, especially using the truck trays.

Rotary Tablet Press (Multi-Station Tablet Press) :

Rotary tablet press is a mechanical device that unlike the single punch tablet press has several tooling station which rotates to compress granules/powder mixture into tablets of uniform size, shape (depending on the punch design) and uniform weight.

It was developed to increase the output of tablets. In rotary tablet press, the compaction force on the fill material is exerted by both the upper and lower punches leaving the powder granules to be compressed in the middle. This is known as accordion type of compression. The capacity of a rotary tablet press is determined by the rotation speed of the turret and the number of stations on the press.

Components/Functional Parts of a Rotary Tablet Press (Multi-Station Tablet Press) :
• Hopper-
The hopper holds the granules/powder mixture (API plus excipient) that are to be compressed into tablets.

• Die cavity –
This is where the powder granules are compressed into tablets and it determines:
a. The diameter of the tablet.
b. The size of the tablet
c. To some extent the thickness of the tablet.

• Feed paddle –
Helps to force the feed/ the granules into the dies especially during faster rotation.

• Punches –
This comprises the upper and the lower punches. They move within the die bore to compress granules into tablets.

• Lower cam track –
This guides the lower punch during the filling stage so that the die bore is overfilled to allow accurate adjustment.

• Cam tracks –
This guides the movement of both the upper and lower punches.

• Depth of fill/capacity control –
This adjusts the lower punch track during the latter part of the fill stage to ensure that the appropriate quantity of granules remains within the die prior to compression.

• Recompression rollers –
This roller gives the granules an initial compression force to get rid of excess air that might be entrapped in the die.

• Main compression –
This roller applies the final compression force needed for the formation of tablets.

• Ejection cam–
Guides the lower punch upwards facilitating the ejection of tablets from the die cavity after compression.

• Take-off Blade –
This is fitted in front of the feeder housing and it deflects the tablet down the discharge chute.

• Discharge chute –
This is where the tablet passes through for collection after being deflected by the take-off blade.

Classification of Rotary Tablet Press :
Rotary tablet press can be classified into several ways but the most important of these classifications is based on the type of tooling with which the machine is to be used with. A tooling set comprises the die and its associated punches.

Basically, there are two types of tooling:
1. “B” type
2. “D” type

The above type of configuration constitutes a majority of the tool configuration used today.

“B” Type :
The “B” type configuration has a normal, punch barrel diameter of 0.750 inches. (19 mm).

The “B” type can be used with two types of die or can be said to have two different die sizes:
1. The “B” dies with a diameter of 1.1875 inches. (30.16 mm), suitable for all tablet sizes up to the maximum for the “B” punches.

2. The smaller “BB” dies (small “B” dies) that has a diameter of 0.945 inches. (24 mm). This die type is suitable for tablets up to 9 mm diameter or 11 mm maximum.

“D” type :
This type has larger nominal barrel diameter of 1 inch. (25.4 mm) and a die diameter of 1.500 inches. (38.10 mm) and thus is suitable for tablets with maximum diameter or maximum length of 25.4 mm.

Tabletting machines are designed to be used with either “B” or “D” tooling but not both. The compression force obtainable in a machine depends on the type of tooling used. Machines that are designed to “B” type tooling exert a maximum compression force of 6.5 tones and machines that use the “D” type configuration exert 10 tones compression force.

There are equally some special machines that are designed with the intention of exerting higher compression forces. The maximum force that can be exerted on a particular size and shape of tablet is governed by the size of the punch tip or the maximum force of which the machine is designed.

Individual manufactures of tablet press have sought to achieve higher output by;
• Increasing the effective number of punches.
• Increasing the number of station.
• Increasing the number of points of compression.
• Increasing the rate of compression torrent speed.
Each of the above approaches has its own advantages and limitations.

Advantages of Rotary Tablet Press (Multi-station tablet press) :
• High productivity can be gained with a minimal amount of labour while saving money.
• Rotary press has an output of between 9000 – 234000 tab/hour thus saves time and meets up with the high demand of tablet dosage form.
• The powder filled cavity can be automatically managed by a moving feeder.
• Rotary press decreases waste of valuable formulation in non-specific tablets.
• The machine allows independent control of both weight and hardness.

Furthermore, you can use this equipment to mix both dry and wet powders. It can mix powders in a wide range of working conditions such as operating without varying pressure zones.

A high shear granulation is a perfect choice for highly cohesive material. Normally, a low shear mixer granulator machine cannot process such materials because they have a high amount of hydrophilic polymer.

2. Key Parts of High Shear Granulation Machine
The number of parts and design may vary depending on the type of machine. It is important to evaluate these parts to be sure that the machine will actually meet the various performance specifications and standards.

Here are key sections of this powder granulation equipment:
• Mixing impeller (number of blades depend on the design)
• Cylindrical mixing drum/bowl
• Multiple choppers
• Discharge port
• Motor to drive the impeller
• Spray nozzle for binding liquid
• Compressed air
• Control system
Generally, these are the basic parts if a granulation machine. Their precise design and coupling mechanism guarantees uniform and high quality granules.

3. Types of High Shear Mixer Granulator
Normally, classification these granulators depend on a range of factors. When choosing these equipment, you may consider the following options:
• Type of dosing system
The available granulation machines may have automatic and manual systems. This may include powder and biding solution dosing system.
• Design of the impeller blade
The impeller blade determines the efficiency of the granulation process. Therefore, an equipment may have varying number of blades.
For instance, a machine may combine about 3-blade impeller. Moreover, the position and design of the impeller blades is also crucial.
In most cases, shear mixers granulator may have impeller tips located tangentially since this eliminates the possibility of dead spots.
Remember, it is the impeller will mix and spread the granulation fluid. Its speed of rotation will depend on the design and specification of the machine.
• Location or position of the impellers
You may go for either horizontal or vertical high shear mixer granulator. These two classifications depend on the position of the impeller.
But, what exactly brings this variation?
For the horizontal high shear mixer granulator, the rotation of the impellers takes place in a horizontal plane. That is, they are side driven.
On the other hand, in the vertical high shear granulators, the shaft rotates in a vertical plane. It can either be bottom or top driven.

4. Consider degree of accuracy
You need to be strict when it comes to this. Remember, in pharmaceutical material processing, accuracy is a key aspect.
First, the design should guarantee uniform granulation. If possible, the granules should be round and strong.
Second, the cylindrical mixing bowl or drum should process a wide range of batch sizes. This will save you the cost of buying new equipment or the time consuming process of changing parts.
Don’t forget that this machine should allow for easy validation of the powder granulation process.

5. Regulatory Requirements
There should be a proof that the equipment adheres to a strict quality manufacturing process. For a fact, the cGMP is a crucial compliance requirement for all pharmaceutical equipment.
The cGMP regulations require that every machine should have tight mechanical seals. It should have better dust handling features while ensuring a high level of hygiene.
This explains why the entire structure of high shear mixer granulator is made from stainless steel. The equipment should be made from FDA approved material while the electrical components should be CE compliant.

6. The Working Principle of High Shear Mixer Granulator
Broadly, the working principle of a high shear mixer granulator involves the following key processes. These may vary depending on the type of machine.
That is:
After switching on the granulator, it will:
• Mix the powder
• Automatically add binder (granulation liquid)
• Powder then becomes wet
• Powder crystals begin to form (nucleation)
• Densify the powder
• Attrition and breakage of granules
That is, as the powder enters the mixing chamber, it is sprayed with the liquid from the nozzle. During this time, the impellers and the hopper mixer the product forming round and strong powder granules.

7. Technology that Granulation Machine Use
High shear granulators feature a wide range of technologies. All these aim to ensure efficiency and the overall reliability of the machine.
For instance, a high shear granulator may feature a fully automatic system. Siemens PLC is a perfect choice for most applications.
The machine may have an automatic discharge of compressed air seal and intelligent control system.

8. Which Factors affect the Quality of Powder granulation?
Choosing the best machine powder granulation machine is not enough. There is a wide range of factors that may influence the formation of the final granules either directly or indirectly.
These include:
• Physical and chemical properties of the powder
• Types and quantity of binder solution
• Design of granulator machine
Let me expound on the last point.
The design of the machines may have many variables and this will affect the granulation process. Some of the key aspects you need to focus on include loading process, impeller speed, chopper speed and applying granulation solution (method and rate).

9. Safety of granulation machine
Apart from the cGMP regulations, this machine comes with an overload relay protection, air pressure switch limit, proper sealing mechanism and the enclosed drive system.

10. Advantages of powder granulation machine
There are a number of reasons why this machine is popular most pharmaceutical processing industry. Some of the key advantages include:
• A fast powder granulation process
• Precise and accurate granule production
• Requires a small quantity of binder solution
• Short powder drying time
• A predictable production process
• Greater densification
• Reduces air pollution due to advanced dust handling properties

11. Disadvantages of powder granulation equipment
A high shear mixer has the following disadvantages:
• It may cause degradation of powder, especially for fragile or thermolabile powders
• Over wetting may cause the production of large lumps
• Produces less compressible granules
• A narrow range of operation conditions
Basically, this explains all the vital aspects of a high shear mixer.

Conclusion
From above, you can see that a high shear mixer granulator is an enclosed container with a range of blending equipment that process the powder either from below, above or sideways. The end result/output of this process is a round and compact granule.

Fluid Bed Dryer Uses and Applications -

Fluid bed dryers : The average consumer has most likely never even heard of them. But in the world of bulk processing, fluid bed dryers have established themselves as dependable and multi-functional processors; capable of completing a variety of critical tasks.

Fluid Bed Dryers :
Fluid bed dryers, as their name suggests, are used for drying materials such as granules, tablets, powders, fertilizers, and plastics. They are particularly popular in production industries like:
• Chemical
• Pharmaceutical
• Food
• Dairy
• Metallurgical
• Dyes
• Other process industries

Fluid bed dryers work on the principle of fluidization, a process in which hot gas or air is introduced into the spaces between solid particles. Upward forces on the particles increase as the air’s velocity increases causing them to equal the gravitational forces below.

A state of fluidization now exists as the particles are suspended in what appears to be a boiling bed of liquid. Each particle is in direct contact with, and surrounded by, the hot gas or air – creating an efficient and uniform drying process.

Fluid Bed Granulation to the Rescue :
Powders do not work well in many applications. They are loosely packed, lack uniformity, and do not flow well. So they need to be crystallized into granules.

In pharmaceutical manufacturing, for instance, granulation means aggregating various primary powder materials to form larger granules. These granules will have greater density, better followability, and uniformity.

Granulation systems can be combined with fluid bed dryers so that the drying, mixing, granulation, finishing, and cooling operations are completed in the same process.

The Importance of Dryers to the Pharmaceutical Industry :
While it’s true that fluidized bed drying can be used in a variety of industries, arguably it has its greatest impact on pharmaceuticals. Fluid bed drying technology has replaced the traditional method of drying products in trays; the result of which has been considerably shorter drying times along with uniform drying conditions.

Fluid bed dryers provide the best solution for drying many products, but especially products within the pharmaceutical industry. With the system, inlet air temperature can be controlled so that the correct amount of moisture evaporates from the surface of the granule. An inlet air temperature that’s too high can result in a surface crust that prevents deeper moisture from being transported to the surface, delaying the drying process rather than accelerating it.

What You Need in a Fluid Bed Dryer :
When you’re looking to invest in a fluid bed dryer system, keep in mind all the features that are important to you and don’t compromise. Consider all that is available in a quality fluid bed processor:
• Heat transfer with minimal energy consumption
• Multi-functional: capable of heating, drying, cooling, coating, and more
• Adaptable to continuous or batch processing
• Vibration to aid in processing
• Manufactured from stainless steel, carbon steel, or nickel alloy
• Customized for your individual needs
• Low maintenance

Advantages of Fluid Bed Dryer in Pharmaceutical Industry -
THE BOMBAY ENGINEERING WORKS

Fluid bed dryer plays an integral role in the pharmaceutical industry. This is due to the many advantages that it offers over the conventional drying techniques.

So far, a number fluidized bed drying studies have established that it is the most reliable and dependable technique in the pharmaceutical industry.

With this information, you can comfortably choose the right pharmaceutical fluid bed dryer.

Advantages of Fluid Bed Dryer :
The available fluidized bed dryers offer a wide range of benefits depending on their unique design.

Below are the main advantages of fluidized bed dryers in the pharmaceutical industry :
1. Fluidized Bed Dryers Guarantee Fast and Homogeneous Drying
• The hot gas/air flows into the system with a velocity greater than the setting velocity of particles. This causes the particles to be suspended in the hot air or gas.
• In this fluidized state, the particle you intend to dry is actually in direct contact with the hot gas or air. Therefore, drying can be done within 10 to 40 minutes.
• Furthermore, the uniform drying is due to the fact that every particle of the solid is surrounded by hot air or gas.
• Whether you opt for a vertical or horizontal fluidized dryer, the working principle will still remain the same.

2. Fluid Bed Dryer is Suitable for Heat Sensitive Products
• Some powders and granules degrade or lose essential properties when subjected to extreme heat or temperatures.
• This makes the conventional drying systems unsuitable for such products.
• The modern fluidized bed designs have sensitive and effective sensors that monitor all essential parameters during material drying process.
• Even with the high rate of mass and heat transfer, you can still control the basic parameters that affect quality of the final product.
Fluid Bed Dryer Control Panel :
• With this control panel, you can easily monitor the temperature and air flow settings.
• That is, with the modern control system, you can adjust all parameters of the inlet air flow.

3. Fluidized Bed Ensures Efficiency in Material Drying
• The fluid bed dryer working principle is such that the particles are dried individually as opposed to the entire bed. Remember, the hot air or gas surrounds all particles and this ensures efficiency in the material drying process.
• Hot air or gas reaches every surface of the particles
• This guarantees 99.9% efficiency in the drying process while saving thermal heat.
• Normally, you’ll find that the thermal efficiency of fluid dryers is 3 times greater than those of other conventional drying systems.

4. Handling Fluidized Bed Dryer is Easy and Less Labor Intensive
• A number of fluid bed dryer designs are such that you can conveniently relocate them from one point to another. This makes handling these machines easy and less labor intensive.
• Furthermore, there are those that have wheels, making them portable material processing equipment.
A Fluid Bed Dryer with Wheels :
• This makes fluid bed dryer a perfect choice for most laboratory and R & D applications.

5. Fluid Bed Dryer Designs Come in a Wide Range of Capacities and Sizes
• Whether you’re in pharmaceutical, laboratory or R&D facility; there is that fluidized dryer design that will suit your unique application requirements. For instance, we have a wide range of fluid bed dryer equipment optimized for different applications.

6. Fluid Bed Dryer has Low Maintenance Cost hence, Reduces Downtime
• This is quite clear from the modular and cGMP compliant designs of our fluid bed dryers for pharmaceutical machines. The equipment is made from high quality stainless steel.
• Ideally, you don’t have to worry about product contamination, dust pollution, rust or tedious cleaning process.
• Furthermore, with the modular design, you can easily replace or modify this machine to suit your unique applications.
• NOTE: In case you have to modify our machines, kindly contact our technical team. Remember, hiring untrained personnel will make your warranty invalid.

7. No Hot Spots on the Final Products
• The hot spot is a common phenomenon in most drying equipment. This is because the products are in direct contact with the drying surface.
Fluid Bed Material Processing Chamber :
• All materials are suspended within the material drying chamber.
• Additionally, you can choose the right capacity of the fluid dryer where there is an excellent mixing of both the particles and air.
• Remember, in other drying applications, you cannot use high temperatures since this may cause damage to the product.
• However, for the case of fluid bed dryer, you can use high drying temperature.
• Again, due to the unique fluid bed dryer working principle; you can use this machine to dry thermolabile products. This is one of the main reasons why fluidization is common in most pharmaceutical industries.

8. Fluid Bed Dryer Is Suitable for both Continuous & Batch Material Processing
• Do you need a drying machine for both batch and continuous material processing?
• Well, I can recommend a fluidized bed dryer since it is a machine that can handle both processes without necessarily doing expensive adjustments or modifications.
Apart from these 8 advantages of fluid bed dryer, other includes :
• No risk of soluble substances migrating
• Reduced dust pollution
• Small size with high production capacity
• High rates of moisture removal
Even though a fluidized bed dryer may offer all these advantages; it may not be suitable for all pharmaceutical applications. It is for this reason that we may advise you to consider other alternatives.

Besides, even when you adopt fluid bed dryer, there are certain challenges that you’ll have to deal with.

“What Can Ribbon Mixers Do For You? – THE BOMBAY ENGINEERING WORKS”

With benefits ranging from ease of cleaning to low energy use, ribbon mixers are an efficient solution for food manufacturers working with powder materials and ingredients.

When it comes to working with free-flowing or sticky powder material, ribbon mixers are a very popular solution throughout the food industry. With a simple structure, ease of cleaning, and low energy use, ribbon mixers are used by heavyweight food manufacturers like Kraft, General Mills, Pepsi, Mars, and many others. Here are some of the benefits and advantages, in greater detail, of ribbon mixers.

Straightforward Design :
Ribbon mixers employ a simplistic design and structure with a limited number of components. The mixer consists of a ribbon agitator, U-shaped vessel, two end plates, and a drive unit. Thanks to its straightforward design, the ribbon shaft can be easily cleaned and troubleshooting and maintenance are conveniently performed. Additionally, the smooth surface and rounded edges ensure any leftover residues can be easily removed.

Drive Unit :
Since the ribbon mixer is only a mild mixing machine, the shaft speed does not need to be fast and therefore does not require a high-powered motor for the drive unit. Additionally, just like the mixer’s overall structure, the structure of the drive unit is very simple and can be separated into a belt drive and direct connection drive. Another added benefit is that there is no risk of oil pollution into the product since the drive unit is located outside and away from the mixing vessel.

Seal Construction :
Food manufacturers prefer simple and effective seal structures that can be easily maintained and changed in the future. With this in mind, the ribbon mixer uses a split packing seal structure that allows for the quick and easy alteration of the packing seal, making the mixer adaptable to a variety of processes.

Discharge :
To reduce residue and limit the amount of wasted space, flap valves are the best choice for discharge. Slide gate valves and butterfly valves are effective options as well, but with roughly 80mm of height space, the flap valve tends to provide the most efficient spatial use, as the valve can lie flush with the bottom of the vessel.

Easy To Clean :
As mentioned earlier, the mixer is designed to be easily cleaned and maintained. The lid on the top of the ribbon mixer allows a worker to easily clean the machine from the top. Additionally, a safety grid and safety switch ensures that there is no potential for injuries to occur during cleaning.

"Filling Technologies Used in Pharmaceutical Industries in Various Countries"

Most pharmaceutical products are packaged as either liquid or powders. Both of these products require advanced machines to handle their manufacturing and packaging.

Liquid filling machines -
There are a number of technologies that are used in different nations for filling liquid medicine. They range from small machines to more complicated systems.

Table top filling machines-
These were early machines used in packaging drugs and food. They ranged from manual, semi automatic and fully automatic systems. They use a pump to deliver the liquid to bottles. They are still in use in the developing nations, Africa, China and India. They are used by herbal medicine companies or those operating at a small scale.

They use electric pumps, peristaltic movement and pneumatic systems. Containers are handled by hand and this increases their susceptibility to biological and chemical contaminants.
Advanced liquid filling machines for vials and ampoules
Liquid filling machines are utilized by many pharmaceutical companies in the world.

They pass most drug agency regulation and codes since they achieve aseptic filling. These can be classified in terms of container type, speed, features, number of fill per operation and functionality.

The mechanism helps machine to fill vials or ampoules, an advanced method of cleaning, disinfecting, sealing and capping the containers.

Though different liquid filler employ a several filling techniques, the basic mechanism entails the use of piston, syringes and nozzles. The movement of piston sucks a metered quantity of the drug which is then delivered to the ampoules.

These machines are very popular in India, China, USA and Europe and are used by a vast number of pharmaceutical companies in packaging. Advanced sensors are used to monitor volume, container, speed, movement, sealing and other processes.

Liquid bottle / Monoblock filling machines-
These are advanced modern machines used to pack liquid chemicals into bottles. They are widely used in pharmaceuticals drug packaging for local and export market. They have advanced features for handling bottles, cleaning them, metering the fluid depending of density, viscosity and chemical properties, pouring the right quantity and filling.

The monoblock type is widely used as it is a complete set will advanced measuring and filling system, ROPP (roll-on-pilfer-proof) where a filled bottle is sealed with a screw able bottle cap inserted by rotating capping machines that descends on the bottle, screws the cap and also forms a tamper proof tuck broken during use.

Dry powder filling machines-
Dry powder filling machines are used as alternative to liquid methods. They are widely applied in packing powders that will be remixed in hospitals or by patients. The main machines applied include

Vacuum/ Injectable dry powders-
This is an advanced method of packing dry powder. The sterile powder is stored in a hopper that uses agitation to move and mix the material. Then powder wheel uses a vacuum to suck the required amount of materials from the hopper. A doctor wheel scoops excess material before it is delivered to the bottle. They have advanced features are widely used in economical packing in North America, China, India and Europe.

Auger type filling machines-
The auger type is more precise and has unbeatable accuracy in filling powders. It features a rotating auger that sucks a definitive amount of powder and transports it to bottles. This is followed by sealing and labeling.

Advanced specialized filling machine-
In addition, many export machines are customized to suit the user needs in terms of bottle size, capping and sealing method as well as other features.

“Rapid Mix Granulator (Operation and Cleaning Guide) : The Bombay Engineering Works”

Operating principle :
A rapid mix granulator is a multi-purpose mixer/processor equally suitable for high speed dispersion of dry powders (including effervescent powders) and their granulation with aqueous or organic solvents. The equipment is designed to achieve rapid mixing and the formation of consistent granules required for the production of high quality pharmaceutical tablets for solid dosage forms of medication. Good mixing and control of granule size leads to fast tableting speeds and high quality products with low rejection rate.

A rapid mixer granulator usually comprises mixing bowl with a bottom entry agitator or impeller for mixing the materials and a side mounted chopper for granulating the mixture. The operating principle is based on agitation of the contents of the bowl at moderate speed and then running the blade of the chopper at high speeds to achieve granulation.

Broadly the operating process therefore takes place in 3 steps -
• Dry materials are mixed at high speed for typically 3 to 5 minutes.
• The mixer is set at a slow speed and liquid binder is added to the dry materials. Mixing of the wet materials typically takes a further 5-10 minutes. The impeller breaks up the mass of material into smaller fragments or granules.
• Wet granulation is achieved by running the mixer at high speed and it typically takes another 5 to 10 minutes to produce granules of 0.5 to 1.5 mm average diameter. The actual granulation time depends on the nature of the starting materials (e.g., density and particle size), the binder, and the speed of the chopper. In this step it is the design and speed of the chopper that determines the uniformity and size of the produced granules. The chopper runs at high speed usually above 200 rpm, and typically between 1200 and 2000 rpm.
Operating procedure :

A. Pre-start Up -
• Ensure that the processing area is clean.
• Check that the correct materials have been selected for the granulation process.
• Remove the “cleaned” label from the granulator after checking the information provided (especially previously used materials).
• Place the equipment label on the machine.

B. Start Up and operation -
• Use protective latex gloves when loading and unloading materials.
• Open the lid of the granulator and load the material to the bowl as per the sequence indicated in the Batch Manufacturing Record (BMR) or specification.
• Close the lid and secure the two locking clamps.
• Fix the dry mixing speed as specified in the BMR. Turn on the power and start the dry mixing process. Run for the specified mixing period.
• Slow the mixer impeller as specified in the BMR to the speed required for binder addition.
• Add the binder solution by supplying through the solution inlet port.
• Check the impeller speed is as per BMR and for the wet mixing process, and run for the required period.
• Increase the speed and set the chopper speed to that required for granulation. Check regularly to ensure that granulation is complete.
• Open the discharge gate and allow the wet mass to flow into a clean FBD bowl, located under the discharge port.

C. Shut Down -
• Stop the chopper and impeller, and open the equipment top lid. Remove any remaining mix by scraping it from the sides of the bowl.
• Check that all materials are removed.
• Switch off the main power supply.

Cleaning Procedures -
1. Cleaning during batch changeover, but with the same product -
• Check that the equipment and area around the equipment is clean.
• Remove the “cleaned” label from the machine.
• Place the equipment “in use” label on the machine.

2. Cleaning during product changeover -
• Check that the equipment and area around the equipment is clean and free from waste or materials from previous products.
• Check and review the “rinse water analysis report” and attach to the BMR.
• Remove the “cleaned” label from the machine.
• Check the relative humidity and room temperature, making sure to document it in the BMR log.
• If the temperature is not within the specified limit, inform the maintenance personnel and do not proceed until the temperature and relative humidity is changed to the required norm.

3. Cleaning at shutdown (e.g., end of day cleaning), or during batch changeover of same product (of ascending potency) -
• Use a vacuum cleaner or lint free cloth to remove loosely stuck powder.
• Dismantle the machine parts and remove them in sequence:
1) Agitator dome
2) Chopper blade
3) Stainless steel bolt
• Use a lint free cloth or vacuum cleaner to clean the dismantled parts.
• Clean the machine and disassemble the parts with lint free cloth.
• Clean the processing area as per the SOP.
• Assemble the parts once cleaned.
• Affix “cleaned” label to equipment.
• Document the cleaning details in the BMR log.

4. Cleaning at Product Changeover (same product of descending potency) – Preventative Maintenance of Contact Parts -
• Clean the mixer and the assembly surface using a moist duster followed by a dry clean duster.
• Fill the bowl with 1/3 of its capacity with water, close the lid and run the mixer and chopper for 5 minutes.
• Collect the washing water e.g., by placing stainless steel drum under the discharge port.
• Open the top lid, remove the agitator blade, and dome by loosening the locking nuts.
• Dismantle the chopper blade by loosening the belt and then remove the blade and washer.
• Transfer the agitator blade and chopper to the washing area, clean both items under a jet of water, and scrub using a clean nylon brush.

“What Can Ribbon Mixers Do For You? – THE BOMBAY ENGINEERING WORKS”

With benefits ranging from ease of cleaning to low energy use, ribbon mixers are an efficient solution for food manufacturers working with powder materials and ingredients.

When it comes to working with free-flowing or sticky powder material, ribbon mixers are a very popular solution throughout the food industry. With a simple structure, ease of cleaning, and low energy use, ribbon mixers are used by heavyweight food manufacturers like Kraft, General Mills, Pepsi, Mars, and many others. Here are some of the benefits and advantages, in greater detail, of ribbon mixers.

Straightforward Design :
Ribbon mixers employ a simplistic design and structure with a limited number of components. The mixer consists of a ribbon agitator, U-shaped vessel, two end plates, and a drive unit. Thanks to its straightforward design, the ribbon shaft can be easily cleaned and troubleshooting and maintenance are conveniently performed. Additionally, the smooth surface and rounded edges ensure any leftover residues can be easily removed.

Drive Unit :
Since the ribbon mixer is only a mild mixing machine, the shaft speed does not need to be fast and therefore does not require a high-powered motor for the drive unit. Additionally, just like the mixer’s overall structure, the structure of the drive unit is very simple and can be separated into a belt drive and direct connection drive. Another added benefit is that there is no risk of oil pollution into the product since the drive unit is located outside and away from the mixing vessel.

Seal Construction :
Food manufacturers prefer simple and effective seal structures that can be easily maintained and changed in the future. With this in mind, the ribbon mixer uses a split packing seal structure that allows for the quick and easy alteration of the packing seal, making the mixer adaptable to a variety of processes.

Discharge :
To reduce residue and limit the amount of wasted space, flap valves are the best choice for discharge. Slide gate valves and butterfly valves are effective options as well, but with roughly 80mm of height space, the flap valve tends to provide the most efficient spatial use, as the valve can lie flush with the bottom of the vessel.

Easy To Clean :
As mentioned earlier, the mixer is designed to be easily cleaned and maintained. The lid on the top of the ribbon mixer allows a worker to easily clean the machine from the top. Additionally, a safety grid and safety switch ensures that there is no potential for injuries to occur during cleaning.

Working and principle of Rapid Mixer Granulator (RMG) -

Rapid Mixer Granulator is a multi-purpose processor equally suitable for high speed dispersion of dry powders, aqueous or solvent granulation, and effervescent products and melts palletisation.

Wet granulation is a common step in the manufacture of many solid dosage pharmaceuticals. Wet granulation can be accomplished in a mixer granulator. A mechanical impeller moves the powder while a liquid binder is applied onto a moving powder bed. Addition of the liquid binder starts the formation of granules. The granulator also has a chopper.
Impeller and chopper are mainly responsible for wet granulation in the rapid mixer granulator.

Rapid Mixer Granulator is designed to achieve excellent mixing and consistent granules at lower operating cost along with higher productivity. Better mixing and closed control of granule size leads to faster tableting speeds with improved quality and least rejections.

The granulation is conventionally performed in the following process steps :
• Mixing of dry material at high impeller and chopper speeds for a few minutes.
• Addition of liquid binder by pouring it on to the powder, while both the impeller and chopper are running at a low speed.
• Wet massing with both agitators running at high speed.

1) Impellers :
Impellers are fixed at the bottom of dome shaped stainless steel bowl. It has fully length and two half-length blades. Impellers are designed such a way that small blade lift the material and full length blades push the material to mix well. These impellers break up the wet mass into small pieces and granules.

2) Chopper :
These are specially designed small blades located at the bottom of the dome. The primary function of chopper is to cuts the lumps into smaller fragments those are mixed equally by impeller and aids the bowl or sprayed onto the powder to achieve a more homogeneous liquid distribution. It rotates at high speed (1440/2880) RPM to give easy and uniform granulation. The speed of chopper is responsible for the size of granule. Chopper does not have any significant effect on the granule size when impeller speed is high (above 200 RPM).

3) Discharge Port :
The discharge port is mounted horizontally into the dome with vertical downward opening. Granules are unloaded in the container through the discharge port. Opening of discharge port is operated by pneumatic cylinder (compressed air cylinder) that requires 3-5 kg/cm2 pressure of compress air.

4) Working Principle :
• The Rapid Mixer Granulator is mixing unit with a bottom entry agitator ad side mounted chopper for granulation. It is used for dry blending, wet mixing, preparation of dough and granulation, i.e. cutting of the wet mass into small size granules. It works on the basic principle of agitation of the contents of the bowl at moderate speed and then running a specially profiled cutter blade at high speeds into the wet mass.
• Dry mixing takes about 3-5 minutes to mix the ingredients; wet mixing takes 5-10 minutes to make the wet mass of material while the granulation process takes 5-10 minute to 0.5 mm to 1.5 mm sized granules.
• Mixing time consumed in processing is depends upon the ingredients quantity and their particle size.

"Advantages of Fluid Bed Dryer in Pharmaceutical Industry -
THE BOMBAY ENGINEERING WORKS"

Fluid bed dryer plays an integral role in the pharmaceutical industry. This is due to the many advantages that it offers over the conventional drying techniques.

So far, a number fluidized bed drying studies have established that it is the most reliable and dependable technique in the pharmaceutical industry.

With this information, you can comfortably choose the right pharmaceutical fluid bed dryer.

Advantages of Fluid Bed Dryer :
The available fluidized bed dryers offer a wide range of benefits depending on their unique design.

Below are the main advantages of fluidized bed dryers in the pharmaceutical industry :
1. Fluidized Bed Dryers Guarantee Fast and Homogeneous Drying
• The hot gas/air flows into the system with a velocity greater than the setting velocity of particles. This causes the particles to be suspended in the hot air or gas.
• In this fluidized state, the particle you intend to dry is actually in direct contact with the hot gas or air. Therefore, drying can be done within 10 to 40 minutes.
• Furthermore, the uniform drying is due to the fact that every particle of the solid is surrounded by hot air or gas.
• Whether you opt for a vertical or horizontal fluidized dryer, the working principle will still remain the same.

2. Fluid Bed Dryer is Suitable for Heat Sensitive Products
• Some powders and granules degrade or lose essential properties when subjected to extreme heat or temperatures.
• This makes the conventional drying systems unsuitable for such products.
• The modern fluidized bed designs have sensitive and effective sensors that monitor all essential parameters during material drying process.
• Even with the high rate of mass and heat transfer, you can still control the basic parameters that affect quality of the final product.
Fluid Bed Dryer Control Panel :
• With this control panel, you can easily monitor the temperature and air flow settings.
• That is, with the modern control system, you can adjust all parameters of the inlet air flow.

3. Fluidized Bed Ensures Efficiency in Material Drying
• The fluid bed dryer working principle is such that the particles are dried individually as opposed to the entire bed. Remember, the hot air or gas surrounds all particles and this ensures efficiency in the material drying process.
• Hot air or gas reaches every surface of the particles
• This guarantees 99.9% efficiency in the drying process while saving thermal heat.
• Normally, you’ll find that the thermal efficiency of fluid dryers is 3 times greater than those of other conventional drying systems.

4. Handling Fluidized Bed Dryer is Easy and Less Labor Intensive
• A number of fluid bed dryer designs are such that you can conveniently relocate them from one point to another. This makes handling these machines easy and less labor intensive.
• Furthermore, there are those that have wheels, making them portable material processing equipment.
A Fluid Bed Dryer with Wheels :
• This makes fluid bed dryer a perfect choice for most laboratory and R & D applications.

5. Fluid Bed Dryer Designs Come in a Wide Range of Capacities and Sizes
• Whether you’re in pharmaceutical, laboratory or R&D facility; there is that fluidized dryer design that will suit your unique application requirements. For instance, we have a wide range of fluid bed dryer equipment optimized for different applications.

6. Fluid Bed Dryer has Low Maintenance Cost hence, Reduces Downtime
• This is quite clear from the modular and cGMP compliant designs of our fluid bed dryers for pharmaceutical machines. The equipment is made from high quality stainless steel.
• Ideally, you don’t have to worry about product contamination, dust pollution, rust or tedious cleaning process.
• Furthermore, with the modular design, you can easily replace or modify this machine to suit your unique applications.
• NOTE: In case you have to modify our machines, kindly contact our technical team. Remember, hiring untrained personnel will make your warranty invalid.

7. No Hot Spots on the Final Products
• The hot spot is a common phenomenon in most drying equipment. This is because the products are in direct contact with the drying surface.
Fluid Bed Material Processing Chamber :
• All materials are suspended within the material drying chamber.
• Additionally, you can choose the right capacity of the fluid dryer where there is an excellent mixing of both the particles and air.
• Remember, in other drying applications, you cannot use high temperatures since this may cause damage to the product.
• However, for the case of fluid bed dryer, you can use high drying temperature.
• Again, due to the unique fluid bed dryer working principle; you can use this machine to dry thermolabile products. This is one of the main reasons why fluidization is common in most pharmaceutical industries.

8. Fluid Bed Dryer Is Suitable for both Continuous & Batch Material Processing
• Do you need a drying machine for both batch and continuous material processing?
• Well, I can recommend a fluidized bed dryer since it is a machine that can handle both processes without necessarily doing expensive adjustments or modifications.

Apart from these 8 advantages of fluid bed dryer, other includes :
• No risk of soluble substances migrating
• Reduced dust pollution
• Small size with high production capacity
• High rates of moisture removal

Even though a fluidized bed dryer may offer all these advantages; it may not be suitable for all pharmaceutical applications. It is for this reason that we may advise you to consider other alternatives.
Besides, even when you adopt fluid bed dryer, there are certain challenges that you’ll have to deal with.

“Tray dryers for drying wet, sticky or granulated products : The Bombay Engineering Works”

A range of technologies are used for food drying which include tray and tunnel dryers, spray, roller and freeze dryers. Tray dryers are quite suitable for drying wet chemicals, powders and crude drugs.

A simple tray dryer is a box-shaped cabinet in which a series of trays are inserted on shelves one on top of the other. Unlike an oven which perhaps has a heater in the base of the cabinet or walls, heat is supplied to a tray dryer by circulating air that has been heated either electrically or by some other means. One or more fans circulate the hot air over the trays.

The best tray dryers are those in which the air flow to the trays can be controlled. The materials to be dried are spread out on top of the trays which may be lined with paper. To shorten cleaning time and prevent contamination, disposable papers are used as tray liners. The trays are often supported on tiers made of wire mesh or perforated steel.

In the latest tray dryers, uniform temperature is achieved throughout a well-insulated cabinet by the use of strategically placed deflectors, which direct the air from one tray to pass over the tray above in the opposite direction.

Air flowing in alternate directions over the trays ensures uniformity of flow and helps to keep the temperature uniform. The air may also be reheated before it passes from one shelf to the next. Air that passes each shelf loses a certain amount of heat (the latent heat of vaporisation of the water that is expelled from the solid material).

Hot air therefore continuously circulates in a tray dryer, and the heat of the air removes the moisture from the material in the trays by forced convection. At the same time, moist air is expelled from the cabinet to vent.

Drying is commonly used after wet granulation. This is the process in which a tablet mix is turned in to a paste with water and then broken up in to granules. Granulation can increase the consistency and the followability of material in the tableting process.

Construction of a tray dryer :
There are several variants of tray dryer, ranging from simple manual systems ideal for batch processes through semi-automatic and automatic systems for processing large quantities.

The basic principles are the same in each case, as follows.
• The dryer consists of a heated box-shaped cabinet into which a number of trays can be loaded. The trays are rectangular or square in shape, typically between 1.2 and 2.4 m2 in area and up to 100 mm deep.
• A minimum of 3 trays can be often seen used in laboratory dryers; however industrial sized equipment may have up to 20 trays.
• The distance between trays and the material being loaded should be 40mm.
• Depending on the design of the dryer, several trays may be stacked on a ‘truck’ or trolley that provides the right separation between trays and which can be rolled in and out of the dryer. Alternatively trays can be inserted manually into runners in the dryer one at a time.
• Directional vanes are located inside the dryer to direct the air to circulate through the trays. In one design, the hot air passes over the bottom tray first, before passing over the second, and so on up to the top of the cabinet. In simple designs, the lower trays can therefore dry out first.

How it Works :
• Trays with wet solid materials are placed in the chamber.
• Fresh air is provided through the inlet and passes through the heater to be heated.
• The hot air is circulated by fans (typically at a rate of 3 to 5 m3/second).
• A turbulent flow or air can lower the vapour pressure of water in the air and reduce the air boundary layer thickness, thereby enhancing the drying effect of the hot air.
• Water diffuses from the interior of the porous material and evaporates from the surface of the solid matter.
• As the contact time is short (air flow rate is large), the amount of water evaporated in one pass through of air is relatively small.
• Some 80-90% of the air that has absorbed moisture from the material is recirculated to the inlet of the fans to mix with fresh dry air. Additional moisture is taken up by the air in the second and subsequent passes of air over the material.
• The moisture collected in the air is discharged through the outlet of the dryer. The high and uniform air flow ensures that there is a constant temperature within the dryer. These features help to achieve uniform drying of the solid matter.
• For wet granules such as tablets or capsules, the desired moisture content may be estimated by measuring the water that is discharged through the air outlet.
• The drying trays are then pulled out of the chamber and taken to the dump station.

Applications :
• Used for drying sticky materials
• Can be used for drying of crystalline or granular material
• Wet mass, paste, powders, and chemicals can all be dried
• A variety of small equipment may also be dried in tray dryers

Advantages :
• Loading and unloading of materials can be done without any losses.
• Batch drying is widely used by pharmaceutical companies.
• Each batch is treated as separate entity.
• Batch size can be small e.g., 250kg or less per batch (pharmaceutical) and 1000kg (chemical).
• Valuable products can be handled efficiently without loss, especially using the truck trays.

Vacuum Tray Dryer :
• A vacuum tray dryer is used mainly for drying of high grade, temperature and oxygen sensitive products. It is suitable for drying hygroscopic substances, which are dried to a very low residual moisture content. Vacuum drying cabinets are often the only means of drying lumpy, glutinous products or products of low porosity.
• As with the normal tray dryer, a vacuum dryer is box-shaped into which trays are loaded and unloaded via a door that has a vacuum seal around the edges. Inside are several heating plates mounted one above the other on above which the trays are placed.
• Since the trays sit directly on the heating plates, the surfaces of each should be as smooth as possible to allow good heat transfer between the heating plates and trays.
• Hot water, steam or oil flow inside the heating plates to provide the heat required for drying.
• The cabinet walls may also be heated by the circulating fluid to prevent condensation of water are indirectly preheated by the heating plates.

When the dryer is loaded with materials it is first heated at atmospheric pressure. Only after all individual product trays reach the same temperature is the cabinet is evacuated and drying commenced. The initial heating phase is necessary to enable a uniform temperature and drying conditions to be established throughout the cabinet. During the main drying phase the vacuum is in the range of 40 to 80 mbar abs.
This may be reduced to a few mbar in the final stages of drying.

Heating temperatures within a vacuum dryer can be much higher than an air dryer, and are often in the range between 800°C and 1100°C. Some systems allow automatic programming of both temperature and vacuum profiles. On completion of the drying, the product can be cooled by circulating of cooling water through the heating plates.

“Rapid Mix Granulator (Operation and Cleaning Guide) : The Bombay Engineering Works”

Operating principle :
A rapid mix granulator is a multi-purpose mixer/processor equally suitable for high speed dispersion of dry powders (including effervescent powders) and their granulation with aqueous or organic solvents. The equipment is designed to achieve rapid mixing and the formation of consistent granules required for the production of high quality pharmaceutical tablets for solid dosage forms of medication. Good mixing and control of granule size leads to fast tableting speeds and high quality products with low rejection rate.

A rapid mixer granulator usually comprises mixing bowl with a bottom entry agitator or impeller for mixing the materials and a side mounted chopper for granulating the mixture. The operating principle is based on agitation of the contents of the bowl at moderate speed and then running the blade of the chopper at high speeds to achieve granulation.

Broadly the operating process therefore takes place in 3 steps -
• Dry materials are mixed at high speed for typically 3 to 5 minutes.
• The mixer is set at a slow speed and liquid binder is added to the dry materials. Mixing of the wet materials typically takes a further 5-10 minutes. The impeller breaks up the mass of material into smaller fragments or granules.
• Wet granulation is achieved by running the mixer at high speed and it typically takes another 5 to 10 minutes to produce granules of 0.5 to 1.5 mm average diameter. The actual granulation time depends on the nature of the starting materials (e.g., density and particle size), the binder, and the speed of the chopper. In this step it is the design and speed of the chopper that determines the uniformity and size of the produced granules. The chopper runs at high speed usually above 200 rpm, and typically between 1200 and 2000 rpm.

Operating procedure :
A. Pre-start Up -
• Ensure that the processing area is clean.
• Check that the correct materials have been selected for the granulation process.
• Remove the “cleaned” label from the granulator after checking the information provided (especially previously used materials).
• Place the equipment label on the machine.

B. Start Up and operation -
• Use protective latex gloves when loading and unloading materials.
• Open the lid of the granulator and load the material to the bowl as per the sequence indicated in the Batch Manufacturing Record (BMR) or specification.
• Close the lid and secure the two locking clamps.
• Fix the dry mixing speed as specified in the BMR. Turn on the power and start the dry mixing process. Run for the specified mixing period.
• Slow the mixer impeller as specified in the BMR to the speed required for binder addition.
• Add the binder solution by supplying through the solution inlet port.
• Check the impeller speed is as per BMR and for the wet mixing process, and run for the required period.
• Increase the speed and set the chopper speed to that required for granulation. Check regularly to ensure that granulation is complete.
• Open the discharge gate and allow the wet mass to flow into a clean FBD bowl, located under the discharge port.

C. Shut Down -
• Stop the chopper and impeller, and open the equipment top lid. Remove any remaining mix by scraping it from the sides of the bowl.
• Check that all materials are removed.
• Switch off the main power supply.

“Tablet Inspection Machine (Operation And Cleaning Guide) : The Bombay Engineering Works”

To ensure consistent high quality of tablet production it is necessary to inspect each and every tablet produced by a tableting machine. Machines have been available for many years that can assist in the manual inspection of tablets. These feed the tablets from a chute onto a conveyor that vibrates or rotates the tablets through 360 degrees so that physical defects can be identified by an operator.

Most recently with the introduction of digital image recognition technology and software, machines are available that can automatically identify and reject tablets that have defects. For either manual or automatic inspection machines, it is essential that the equipment is thoroughly cleaned before starting the inspection of any new batch of tablets. The following is a brief guide that can be applied to the operation and cleaning of most tablet inspection machines.

Pre Start Up :
1) Check that the area in which the inspection machine is located and ensure that the machine is clean, and there are no remnants of previous products in the area or in the equipment.
2) Check the relative humidity and temperature of the work area and document it in the logbook.
3) If the temperature is not within the allowable limits, inform the maintenance, department and do not start the operation.
4) If temperature is within limits, start the inspection operation.
5) Ensure that the equipment is correctly labelled for the particular batch of product.
6) Get line approval from Quality Assurance (QA) department to start the process.

Operation :
1) Switch the mains electricity ON.
2) Check for any abnormal noise by pushing the start button.
3) To collect the inspected tablets, place tared polythene lined duly labelled high-density polyethylene container below the machine’s discharge chute.
4) Place the required batch of tablets into a trolley and place trolley near the inspection machine.
5) Manually feed the tablets to the machine’s hopper.
6) Set the vibration or rotation of the conveyor as required.
7) Switch on the conveyor belt.
8) In the case of manual inspection, check for any defects on the tablet as the move along the conveyor.
9) Collect the recoverable rejected tablets from the rejection box and place into a polyethylene container.
10) When the container at the discharge chute fills up, replace it with a similar container.
11) Remove the container and close the bag with a tie band, and place it in a different trolley to the product.

Shut Down :
1) When the tablet inspection is complete, switch the machine off.
2) Isolate the main electricity supply.
3) Move the product tablets to the intended placement area.
4) Remove the machine status label and dispose of it.

“What Can Ribbon Mixers Do For You? – THE BOMBAY ENGINEERING WORKS”

With benefits ranging from ease of cleaning to low energy use, ribbon mixers are an efficient solution for food manufacturers working with powder materials and ingredients.

When it comes to working with free-flowing or sticky powder material, ribbon mixers are a very popular solution throughout the food industry. With a simple structure, ease of cleaning, and low energy use, ribbon mixers are used by heavyweight food manufacturers like Kraft, General Mills, Pepsi, Mars, and many others. Here are some of the benefits and advantages, in greater detail, of ribbon mixers.

Straightforward Design :
Ribbon mixers employ a simplistic design and structure with a limited number of components. The mixer consists of a ribbon agitator, U-shaped vessel, two end plates, and a drive unit. Thanks to its straightforward design, the ribbon shaft can be easily cleaned and troubleshooting and maintenance are conveniently performed. Additionally, the smooth surface and rounded edges ensure any leftover residues can be easily removed.

Drive Unit :
Since the ribbon mixer is only a mild mixing machine, the shaft speed does not need to be fast and therefore does not require a high-powered motor for the drive unit. Additionally, just like the mixer’s overall structure, the structure of the drive unit is very simple and can be separated into a belt drive and direct connection drive. Another added benefit is that there is no risk of oil pollution into the product since the drive unit is located outside and away from the mixing vessel.

Seal Construction :
Food manufacturers prefer simple and effective seal structures that can be easily maintained and changed in the future. With this in mind, the ribbon mixer uses a split packing seal structure that allows for the quick and easy alteration of the packing seal, making the mixer adaptable to a variety of processes.

Discharge :
To reduce residue and limit the amount of wasted space, flap valves are the best choice for discharge. Slide gate valves and butterfly valves are effective options as well, but with roughly 80mm of height space, the flap valve tends to provide the most efficient spatial use, as the valve can lie flush with the bottom of the vessel.

Easy To Clean :
As mentioned earlier, the mixer is designed to be easily cleaned and maintained. The lid on the top of the ribbon mixer allows a worker to easily clean the machine from the top. Additionally, a safety grid and safety switch ensures that there is no potential for injuries to occur during cleaning.

The Vacuum Tray Dryer is equipment used in the drying of the heat sensitive and hygroscopic materials.

DESCRIPTION :
Vacuum Tray Dryer is a modified form of the vacuum still. The Vacuum Tray Dryer which is in common use in the pharmaceutical industry is called vacuum oven. It consists of a jacketed vessel made of materials which can withstand vacuum with in the oven and steam pressure in the jacket.
The oven can be closed by a door that can be lacked tightly to provide an air tight seal.

The oven is connected to a vacuum pump through a condenser and a receiver. At the pressure of about 0.03 to 0.06 bars vacuum oven is operated generally.
At this pressure water boils at 25 -35 degree centigrade. In the pharmaceutical industry an oven of the size of about 1.5 m cubes having 20 shelves are commonly used.

Now days the vacuum ovens with a number of small compartments with small doors are available rather than one big compartments with a heavy door.

PRINCIPLE :
In Vacuum Tray Dryer materials is dried by the principle or applications of vacuum. The water boils at a lower temperature when the pressure is lowered by creating the vacuum. So evaporation of water takes place faster.

CONSTRUCTION :
The construction of the Vacuum Tray Dryer is made of with stand high vacuum pressure with cast iron heavy jacketed vessel which with stand the steam pressure in the jacket. It has enclosed space and divided in to 20 hollows shelves portions which are part of the jacket.

These shelves provide conduction of heat due to larger surface area about 45 to 50 m square provided by shelves and metal trays are placed over the shelves for keeping the materials. The oven door is locked tightly to give an air tight seal and is connected to a vacuum pump by placing condenser.

WORKING :
• The trays which are present in the dryer are used to dry the materials which are placed on the shelves and the pressure is decreased up to 30 to 60 kps by vacuum pump.
• Door is closed firmly and steam is passed through the space of jacket and shelves. So that the heat transfer takes place by the mechanism of conduction.
• Be vacuum evaporation the water is taken out from the material at 25 - 30 @c.
• Water vapour passes in to the condenser and after drying vacuum line is disconnected then the materials are collected from the trays.

PHARMACEUTICAL APPLICATIONS :
Vacuum Tray Dryer can be used for the drying of the following :
1. Heat sensitive materials, Dusty materials, hygroscopic materials, toxic materials can be dried in this vacuum dyer.
2. Feed materials containing the solvents are also dried by this vacuum dryer. The solvent material can be recovered by the condensation process.
3. Drugs which are required as porous end products.
4. Friable dry extracts can be obtained through this drying process.

ADVANTAGES :
1. Handling of the materials is easy in this drying because of tray arrangement inside the dryer.
2. It is easy for switching over to the next materials.
3. Hollow shelves which are electrically heated can be used.
4. It provides large surface area. So the heat can be easily transfer throughout the body of the dryer and fast drying action takes place.
5. Hot water can be supplied throughout the dryer which helps in drying process at the desired temperature.
