It is important in the plastic industry to reduce the residual moisture of the plastic granulate.
Therefore most of the plastics need a material drying before processing.
In the hot air or vacuum dryer the residual moisture is reduced.
It should be noticed, that each plastic needs different temperatures and times for the drying to reach a minimal residual moisture, while the material is not going brittle.
