Forced Draft Tray Dryer.
Forced Draft Tray Dryer
The set-up is designed to demonstrate and stimulate the moisture
removal by heat under forced draft action created by hot air stream
set-up consists of an insulated double wall chamber. Inside the chamber
a tray is attached directly to an electronic weighing balance, which is
fitted on top outside the chamber. Material for drying is placed in the
tray and regular loss of weight is monitored. Air from blower passes
through heating chamber to produce hot air works as the drying agent
entered from one side of the chamber and leave the chamber from other
side removes the moisture from the tray. An arrangement is made to vary
and measure the airflow rate. A digital temperature controller is used
to control and measure the temperature of air stream.
