Description

Convection dryers are often used for drying solids in food technology. The can be used to investigate and demonstrate the process of convection drying of granular solids.
Four corrosion resistant removable plates are available for drying the solid. They are placed in a drying channel. The plates containing the solid to be dried are exposed to an air flow in the channel. The air flow heats the solid and also removes any moisture 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.

Learning Objectives/Experiments
Influence of air temperature and humidity on drying intensity
Plotting of drying curves with constant external conditions
Determination of drying rate with different air parameters and different solid properties
Evaluation of drying processes using energy and mass balances

Features
Pneumatic pressure-lifting of solids in a vertical tube
Transparent tubes and tanks to observe different transport states
Practical experiments on a laboratory scale

Specification
Drier for investigating convection drying of solids
Drying on 4 corrosion resistant plates in a drying channel with an air flow
Adjustment of air velocity via speed of fan
Air heating with controlled heater
Digital balance for measuring the change of weight during drying
1 combined sensor for measurement of humidity and temperature before and after the solid sample
1 air velocity sensor
