Method for processing plant materials, composting device and method for composting plant materials in heaps

摘要

A plant- or bio-waste composter is novel in having a conveyor (5) transferring the material to a compactor (18), with a comminutor (20) comprising a cutter insert (21) and a perforated disc (24). Pref. a pre-comminutor (39, 43) for large or long plant sections is provided at the entrance (17) of the compactor (18). The cutter insert and perforated disc are interchangeable, allowing different types to be inserted, to cope with materials of differing constitution. The edges of the perforations in the plate act against a pre-cutter. A second cutter behind the plate, works with the rear edges of the perforations. The perforations may be round, elliptical or slotted, with variable diameter or size.
