The invention relates to a mincing machine with cutting elements and a screw conveyor (10) which is rotatably mounted in a housing and is connected to a blade pin (20). The blade pin (20) is advantageously connectable and can be easily disconnected again.

A grinding machine includes first feed screw, first head, first center pin, first knife assembly, bushing and first orifice plate. Second feed screw is coupled to first center pin and rotates within second head. Second feed screw is positioned against the bushing such that the bushing acts as a thrust bearing. Second center pin is coupled to second feed screw and is configured to rotate a second knife assembly. Second orifice plate is arranged on second center pin. Second mounting ring can be linearly adjusted relative to second head to axially position second orifice plate between a stop shoulder of second head and a lip of second mounting ring. Second feed screw may include a plurality of flights arranged in a split flight configuration including one or more ingress end flights and one or more egress end flights.

A method to grind meat in a grinder, includes: providing the meat to the grinder via a hopper where the hopper includes a feeder worm for feeding the meat to a process unit. The process unit has a rotating processing worm and a cutting set. The rotating processing worm can receive the meat from the feeder worm and convey it to the cutting set, which grinds the meat. The method involves automatically adjusting the revolutions per minute of the rotating processing worm in response to a pressure creation in the process unit.

The invention relates to a cross-shaped support (10) for a meat-mincing machine. The cross-shaped support (10) has a hub (11) with a central bore (15), an outer ring (13), and multiple webs (12) which extend between the hub (11) and the outer ring (13). A groove (14) is provided on the exterior of the outer ring (13) in order to support the cross-shaped support (10) in the meat-mincing machine in a rotationally fixed manner. The cross-shaped support (10) additionally functions as a tool, for example the cross-shaped support has projections (16) which allow a simplification of the assembly or disassembly of the knife pin from the meat-mincing machine (FIG. 1).

A mincing drum for a cutting and separating device, at the first end section of which there is an inlet opening and at the second end section of which there is an outlet opening, a plurality of cutting openings being arranged in a pressure housing section of the mincing drum and passing continuously through the pressure housing section from an inner wall to an outer wall, each cutting opening having, on the inner wall, a cutting opening edge facing the outlet opening and a drawing-in opening edge facing the inlet opening. The cutting performance of the cutting and separating device and the quality of the desired food component is significantly improved as a feed channel which is recessed relative to the inner wall is situated between the cutting opening edge and the drawing-in opening edge.

The present invention relates to a method to grind mass in a grinder (1) wherein the mass is provided to the grinder (1) via a hopper (5) and transported by a feeder worm (2) to a rotating processing worm (3) which conveys the mass towards a cutting set (4) which grinds the mass and wherein the feeder worm (2) initially rotates in a first direction. During production the feeder worm (2) is periodically reversed and/or the speed of rotation of the feeder worm (2) is reduced in case the volume between the feeder worm (2) and the processing worm (3) tends to get blocked with the mass.

A separation assembly for a food product separating machine configured to separate meat product from bone product includes a separation chamber defined by a circumferential side wall, a longitudinal axis, and a radius. The separation chamber includes a plurality of apertures disposed in the circumferential side wall and at least one V-shaped groove disposed along an inner surface of the circumferential side wall. The V-shaped groove is defined by a vertex and an angle bisector of the vertex and is formed in an inner surface of the chamber.
