Device for cutting meat

A device for cutting edible products in the form of lumps, especially frozen pieces of meat having dimensions up to 250 mm.times.250 mm.times.250 mm, said device comprising:

• cutters for rotating in a cutter housing, said cutters being mounted nonrotatably but readily interchangeably on a shaft stub of a three-phase motor, said shaft stub being horizontal or inclined relative to a horizontal plane;
• each cutter of said cutters having an axial conveyor component;
• said cutters or rotating at rotational speeds between 500 rpm and 3,000 rpm;
• said cutters having a configuration and an axial spacing such that said frozen pieces of meat are cut to granulated meat having a grain size of 2 to 8 y mm;
• wherein a plurality of said cutters comprise double cutters having two blades, each blade of said blades including a chamfer provided at a leading edge, said chamfer having a grinding angle between approximately 25.degree. and approximately 30.degree.;
• said cutter housing having a delivery opening in a lowest area, for continuous delivery of said granulated meat by gravitational force only;
• said cutter housing being adjacent a continuously operating feeding device comprising a feed screw for feeding the frozen pieces of meat against a plane of rotation of a first cutter of said cutters,
• said feed screw for rotating at a rotational speed between 20 rpm and 200 rpm in a direction opposite to that of said cutters,
• said cutter housing having an inside wall circumferentially encompassing said cutters, and said inside wall being smooth,
• wherein a radial distance between ends of said rotating cutters and said inside wall comprises a gap distance of less than approximately 4 mm,
• wherein a lower edge of a housing of said feed screw is flush with a lower edge of said cutter housing;
• and
• wherein a first diameter of a feed screw housing corresponds to approximately half a second diameter of said cutter housing.
