Rotary Dryer
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.
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
