Abstract: A rotary cutter means for use with meat cutting or extruding devices including an apertured flat faced discharge means and with the rotary cutter means comprising a planar cutter knife having a plurality of cutter blades extending substantially radially from a support hub. These blades each have an overhanging leading edge axially spaced from the flat face of the discharge means and the blades each have a flat bearing surface thereon positioned adjacent the flat face of the discharge means, the cutting edge being at the leading edge of this flat bearing surface. The device also includes radially extending slots in each of the flat bearing surfaces of the cutter blades and extending the length thereof to form a pair of parallel cutting edges thereon positioned in spaced circumferential relation in the cutter knife.

Abstract: A meat cutting or grinding device including a frame in which an extruding means is provided for forcing meat along the axis of the extruder, a cutter means is provided for cutting the meat into pieces as it is being discharged, and the device includes an apertured extrusion plate perpendicular to the axis of the extruding means and made from low friction material, which discharge plate is positioned in a second discharge or carrier plate for reinforcing and supporting the low friction discharge plate in the cutting device, whereby the device will stand high extrusion and compression pressures. Specially shaped cutter blades are present in the cutter and grinding device.
