Functioning of Screw Compactor for Dewatering Defrosted Ice Cream

During separation, the waste stream is split into two: The liquid can be discarded as waste water, or in some cases, it can be collected and sold for other purposes, e.g., animal feed or energy production. The solid becomes dry and can go to incineration at a lower cost or be sold to recycling companies.

The defrosted ice cream can be fed into the screw compactor manually or with a conveyor belt into the vertical hopper. The liquid is pressed out through a hole matrix, and the compacted material is slowly pushed out of the departure tray and collected in a container.
