Pharmaceutical Dryers

Dryers are used in a variety of industries, such as the food processing, pharmaceutical, paper, pollution control and agricultural sectors. Diverse materials need to be dried in completely different businesses, such as chemicals for research and medical concerns, paper for printing and packaging operations and edible materials for further processing into popular foods and snacks.

Dryers are used to remove liquids or moisture from bulk solids, powders, parts, continuous sheets or other liquids by evaporation or sublimation. Dryers can be broken up into two main types: direct and indirect. Direct dryers convectively heat a product through direct contact with heated air, gas or a combusted gas product. Indirect dryers conductively heat a product through contact with a heated wall.

There are various types of Dryer used in Pharmaceutical Industries

• Fluid Bed Dryers
• Tray Dryer
• Vacuum Tray Dryer
• Rotary Dryer

what is a tray dryer?

The tray dryer is used for the drying of the wet products of the crude drugs, chemicals, powders or the granules, etc.

Cabinet including heater at the bottom which is the simplest form of drying is a laboratory oven. 

These ovens are of very little value because there is no control of the heat transfer or humidity.

Assuming a fan fitted to the oven. In that case, the forced hot air circulated, increasing the heat transfer, and reducing the local valor concentrations. Despite this, there is no adequate control.

The best type of tray dryer or tray drying machine is that of the directed circulation form. The controlled flowing system offers heated air across the material. 

The material spread on the tiers of the trays to dry quickly. The trays used have solid, perforated, or wire mesh bottoms.

The screen tras are lined with paper to circulate across rather than through the drying materials.

The paper is used as a disposable tray liner to reduce cleaning time and prevent contamination.

The uniform temperature and air in a modern tray dryer use a well-insulated cabinet with strategically placed fans and heating coils.

There is an alternate arrangement of the shelves so that air can flow uniformly without any obstructions. The fitted heater design helps provide reheated air before passing through each frame.

When the air passes over each shelf, a certain amount of heat helps provide latent heat for vaporization. The correct design offers reasonable control of heat and humidity in such types of dryers.

Tray drying process

tray dryer is a conventional drying equipment with enclosed insulated chambers and trays placed on top of each other in a trolley. the driers are used in process where drying and heating are crucial part of the industrial manufacturing process such as in food products, pharmaceutical, dyestuff and chemical manufacturing among others .the material to be dried are either solid or wet are placed on the trays
