6.1. General Information
The dehumidified air dryers were developed for drying plastic granules. Due to their compact con- struction, they can be employed next to the processing machine (drying hopper on the processing machine) or with one or more drying hoppers as a movable facility (compact facility).
The dryers work according to the dehumidified air principle, i.e., the air is not only heated but also dehumidified before it flows through the drying hopper.
In this manner, plastic granules can be dried down to a very small residual moisture content.
The drying temperature can be adjusted, if necessary, up to a maximum of +180 °C (356°F) (up- per limit). Due to the heat that is released during water absorption in the drying cells, the lower limit of the dehumidified air temperature is approx. +60 °C (140°F).
The drying takes place continuously, i.e., there are no rest periods due to regeneration of the dry- ing agent.
F
The dryer is rated for continuous operation.
The dryer may only be put into operation if the drying hopper is filled.
