Abstract
Abstract Apparatus for processing garbage according to the present invention includes a conveyor belt to convey the garbage to a grinder that comminutes the raw garbage. A hopper receives the comminuted raw garbage from the grinder and supplies it to feed screws feeding the raw comminuted garbage onto heated metal platens that compress and dry the garbage. A scraper is provided for removing adhered garbage from the platens, and a second hopper is disposed to receive the compressed and dried garbage scraped from the metal platens and to deposit it into a second grinder where it is comminuted for final disposition in containers.
