Producing liquid waste material fraction from type-sorted domestic waste and that from food preparation and with high content of biologically degradable components involves liquid waste fraction pressed out through apertures in press curve

摘要

The equipment for producing a liquid waste material fraction from a type-sorted domestic waste material and that from food preparation and with a high content of biologically degradable components involves the liquid waste material fraction pressed out through apertures in a press curve (36) with the aid of a press worm (33), whilst a semi-dry press residue is thrust outwards through a nozzle outlet (38). The type-sorted material, after removal of packaging, is fed to a volumetric feed device (21), which feeds it under pressure into the worm press. The press is so formed that a large part of the waste material is pressed out as a liquid fraction through the narrow, longitudinal gap-type apertures in the press curve (36).
