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.

TYPICAL EXPERIMENTS
  • Tray drier drying curves.
  • Effect of particle size.
  • Effect of air velocity.
  • Effect of air temperature.
