Working Principle of Tray Dryer. The principle involved in tray dryer is forced convection where hot air is circulated continuously over the wet material. Water vapours formed, mix with the circulating air and are eliminated through the outlet provided.
A tray dryer is a widely used industrial drying equipment designed for drying various materials in batches. It typically consists of trays stacked on top of each other …
This dryer type operates by passing hot air over the surface of a wet solid that is spread over trays arranged in racks. Tray dryers are the simplest and least-expensive dryer type. This type is most widely used in the food and pharmaceutical industries. The chief advantage of tray dryers, apart from their low initial cost, is their versatility.
Tray Dryer - Construction, Working, and More. Tray drying is a batch process used to dry materials that are liquid or wet cake. Tray drying works well for material that requires more gentle processing or cannot be atomized in an airstream due to viscosity. This dryer is well utilized for drying wet products like crude drugs, chemicals, powders ...
