How does a
screw press
work?
The material which has to be dehumidified will be placed into the hopper. The rotational movement of the screw conveys the material into the dehumidification area. The dehumidification section consists of a slotted sieve cylinder, whose outlet opening is closed by a spring-loaded pressure plate. The permanent supply of material causes compaction of the material in the dehumidification area and the liquid will be squeezed out. This liquid can drain through the drain hole and be reused. Due to the increasing pressure in the dehumidification area, the pressure plate is displaced, the dehumidified material falls into the container, and then the pressure springs press the pressure plate back against the dehumidification area and close the outlet opening. Optionally, the dehumidification screw can be equipped with a return pump station.
