Description

Convection dryers are often used for drying solids in food technology. The apparatus can be
used to investigate and demonstrate the process of convection drying of granular solids.
Three corrosion resistant removable plates are available for drying the solid. They are put in
a drying channel. The plates containing the solid to be dried are exposed to airflow in the
channel. The airflow heats the solid and also removes the quantity of humidity that is
released. Air velocity can be adjusted by the speed of a fan. An adjustable heater allows the
heating of the air. The transparent door in the drying channel allows the drying process to be
observed. A digital balance can be used to follow the changes in weight of the solid due to
evaporation or vaporization of quantity of humidity during operation. The air temperature
and the relative humidity of the air are measured and digitally displayed by a single combined
temperature and humidity sensor before and after the airflow passes over the solid. A further
sensor measures the air velocity. The relevant measured parameters (changes in weight,
humidity, temperature, air velocity) can be recorded from the indicator for processing and
calculation
