Description and Specification for Lab Tenders
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.
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 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.
