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.

Detail description

A tray 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 parameters is fixed outside the dryer.

Key controlling parameters of Tray dryer are Blower CFM, Steam Temperature, Humidity control. These are achieved by VFD based blower control, control valves for steam and chilled water. A very fine temperature control can be achieved with highly responsive PLC and SCADA system.
