ABSTRACT:
This invention provides means whereby the liquid component can be separated from the solids in food waste and garbage. The invention provides a spinning perforated drum with an internal filter bag through which liquid and fine solids pass by centrifugal force. The separated liquid is filtered through a finer filter to make the water acceptable for municipal sewer disposal.
