Tray Dryer Working Principle | Manufacturers and Suppliers

Tray Dryer Working Principle:

A dryer which is used for drying of the wet products like crude drugs, chemicals, powders or the granules etc. is known as tray dryer. A laboratory oven is the very simple form of it which contains a cabinet with a heater at the bottom. The values of these ovens are very less because of its uncontrollable heat transfer or humidity meter.

When we fit a fan on the oven, then the circulation of the forced hot air is started. This process is very helpful for reducing the local flour concentrations and also for increasing the heat transfer. The directed circulation form is the best type of a tray dryer. In these Dryers the air is heated and is focused across the object in a controlled flow.

The material is spread which we want to be dried on the tiers of the trays. The tray, which is used in this process must have perforated, solid or wire mesh bottoms. For the circulation of the air across the drying materials we lined the screen trays with paper. A definite amount of heat was given to each and every shelf at that time when, the air passes over it to provide the latent heat of vaporization. A good control of humidity and heat is provided by this kind of dryers.
