ABSTRACT:
A self-feeding and self-emptying food grinder is provided of a walled-hopper type with food receiving and bottom rectangular discharge openings. To this standard structure which may be mounted on a driving shaft, an improvement is provided that includes a foraminated outwardly directed convex grate enclosing and over the discharge opening and a driven cutter and move assembly transporting food from the hopper is provided with the assembly including a split drum smaller than and rotatably mounted off center in the discharge opening substantially along the parting line between the opening and grate, the drum being disposed to contact the grate on rotation at only one portion thereof. The drum is provided with diametrically opposite radially directed slots and a blade structure in the form of an open-centered frame is slidably mounted in the slots to alternately fully extend into the hopper and fully retract into the drum at the contact position of the drum and grate by the blade sliding along the grate on rotation. This forms a constantly decreasing space between the drum and grate on drum rotation whereby food is fed into and squeezed through the grate to empty the hopper. The entire structure is easily disassembled for cleaning and guide means is provided on the drum to fixedly locate the sliding cutter assembly.
