A tray or Compartment Dryer is an enclosed insulated chamber in which trays are placed on top of each other in trolleys. The material to be dried either wet or solids are placed in the trays. Heat transfer is by circulation of hot air by electric heaters or steam in radiator coils. Blower fans are installed inside to ensure proper circulation and transfer of heat. A control panel to control the temperature and other parameteres is fixed outside the dryer. These dryers are available in Mild Steel, Stainless Steel or Al construction. Used for Drying of Pigments, Food, Bakery, Electrodes, Chemical and Plastic Powders.
