Drying Unit – by Evaporation

DESCRIPTION

 

This unit is designed to dry solid products by evaporating liquids (volatile or non-volatile) found in them.

Heated air is used to dry the material.

Observation of the drying process and measurement of various parameters: air temperature, moisture content of the material, humidity of the air…
