ROTARY DRYER APPARATUS

Product Description

The setup is designed to demonstrate andstimulate the moisture removal by heat under forced draft action created by hotair stream and shower of moist solid due to rotary action of dryer drum.

The set-up consists of a long cylindricalshell slightly inclined towards the outlet rotating at low RPM.

Counter current hot air from blower passesthrough heating chamber to produce hot air works as the drying agent enteredfrom one side of the rotating shell and leave from other side removes themoisture from the moist solids.

High moisture content feed enters from one endof the shell and low moisture content product discharges from the other end ofshell. As the shell rotates internal flights lift the solids and shower themdown through the interior of the shell. This action increases the contact of wetsolid against hot-air making the dryer very effective.

An arrangement is made to vary and measure theairflow rate. A digital temperature controller is used to control and measurethe temperature of air stream.
