The invention relates to a reliable cutting set system for a meat mincing machine. The mutually matched coding (14, 24) between knife pins (10) and the cutting set element (20) prevents an incorrect installation of the cutting set element (20) after a cleaning process or during the initial assembly, thereby increasing the operational safety. The invention allows a detection of the correct cutting set element (20) of a cutting set system and thus an unambiguous allocation of the cutting set element to a knife pin (10) of a cutting set system.

An embodiment described herein provides for a system for removing or installing a grinder plate. The system includes a grinder plate having a disk shaped body which defines a central cylindrical aperture extending therethrough and a first one or more screw threads are defined in the central aperture. The system also includes a plate handling tool having an elongated body defining a second one or more screw threads on an external surface proximate the first end. The first one or more screw threads of the plate are configured to mate with the second one or more screw threads of the tool.

The invention relates to a blade, more particularly for a meat grinder. The blade (10) has a collar-type sealing ring (18) between the hub (11) and the inner ends of the blade wings (14). The sealing ring (18) has the same height as the hub (11) as the adjacent sealing ring (18) has or the hub (11) has a smaller height. The hub (11) thus does not impede the rubbing of the cutting edges (16, 17) of the blade (10) or the rubbing of the sealing ring (18).

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 meat grinding reclamation system is disclosed herein. The system uses a first meat grinder coaxially coupled to a second meat grinder. The first meat grinder separates meat from undesired material such as gristle, hard fat, connective tissue, sinew, and bone. Most of the meat is ground, while the undesired material is remixed into a small portion of the meat and is moved from the first grinder into the second grinder. The second grinder separates remaining meat and carrier meat from the undesired material, grinding the reclaimed meat and moving it into a bin with the originally separated meat. The waste material is moved to a waste bin. Pressurized air may be used to prevent the waste material from becoming clogged in the system.

The invention relates to a meat grinder, having a housing (12), a conveying device, and at least one cutting-unit part (22). A meat grinder according to the invention comprises a housing (12), at least one conveying device for conveying material to be ground from an inlet opening to an outlet opening, and at least one cutting-unit part (22) arranged in the housing (12). At least one transponder (42) is arranged in or on the at least one cutting-unit part (22) and at least one communication device (36) for communicating with the transponder (42) is arranged in or on the housing (12) in such a way that data exchange between the communication device (36) and the transponder (42) is enabled.
