Natural Draft Tray Dryer

The set-up is designed to demonstrate and stimulate the moisture removal by heat under natural draft action created by hot air stream.

The 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 works as the drying agent by natural action removes the moisture from the tray by passing towards the top openings. A digital temperature controller is used to control and measure the temperature of air stream.
