Convection Drying- Engineering Lab Training Systems.
Technical Description
Convection dryers are often used for
drying solids in food technology. The Convection Drying can be used to
investigate and demonstrate the process of convection drying of granular
solids. Four corrosion resistant removable trays are available for
drying the solid. They are positioned in a drying channel. The trays
containing the solid to be dried are exposed to an airflow in the
channel. The airflow heats the solid and also removes the moisture that
is released. Airflow rate can be controlled by adjusting the speed of a
fan. Air temperature is controlled with an adjustable heater. The
transparent door in the drying channel allows the drying process to be
observed. Digital scales can be used to follow the changes in weight of
the solid due to evaporation or vaporisation of moisture during
operation. The air temperature and the relative humidity of the air are
recorded and digitally displayed by combined temperature and humidity
sensors before and after the airflow passes over the solid sample. The
hand-held anemometer provided, measures airflow rate.
The relevant measured parameters can be transferred directly to a PC, where they can then be further processed.
