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 l

• Anemometer Air flow measurement

The set-up is designed to demonstrate and stimulate the moisture removal by heat under forced draft action created by hot air stream and shower of moist solid due to rotary action of dryer drum.

The set-up consists of a long cylindrical shell slightly inclined towards the outlet rotating at low RPM. Counter current hot air from blower passes through heating chamber to produce hot air works as the drying agent entered from one side of the rotating shell and leave from other side removes the moisture from the moist solids. High moisture content feed enters from one end of the shell and low moisture content product discharges from the other end of shell. As the shell rotates internal flights lift the solids and shower them down through the interior of the shell. This action increases the contact of wet solid against hot-air making the dryer very effective.
