TH 610 TRAY DRYER
GENERAL DESCRIPTION

This is a basic unit for studying of tray drying by hot air.

The unit consists of a rectangular duct. Air is drawn into the duct by an axial flow fan at the front end of the duct. Fan speed is adjustable. A bank of electric heaters behind the fan raises air temperature. Behind the heater is a drying compartment with transparent access door. A rack of trays is suspended from a balance above the duct. Temperatures and humidity before and after the drying trays are measured.
