“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.

• 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.

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.

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
