Tray Dryer

The tray dryer is a horizontal chamber with removable trays in the center area. There is a fan and heater located at the air feed end, where the air temperature and speed is controlled. Air passes over the trays, drying the material on them. The students determine drying rates at equilibrium conditions, use wet and dry bulb thermometers, use a psychometric chart and do a mass balance for water in the system.
