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 method to grind meat in a grinder, comprises: 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 comprises a rotating processing worm and a cutting set. The rotating processing worm is configured to receive the meat from the feeder worm and convey it to the cutting set which grinds the meat. The method further comprises automatically adjusting the revolutions per minute of the rotating processing worm in response to a pressure creation in the process unit.

A rotor locking device in a crusher is arranged for locking a rotational position of a rotor shaft. A shaft engager includes a female toothed mating surface for coaxial engagement with a male mating surface at an end of the rotor shaft to rotationally interlock the same. A fastening portion with engager apertures overlaps with a bearing mount surrounding the rotor shaft so it can be fastened therewith. The engager apertures are circumferentially elongated in order to accommodate alignment with fastening points in the bearing mount, at least when a closest rotational mating position is chosen for alignment. This enables any rotational position of the rotor shaft to be locked for safety before having to access the crusher chamber, especially when the rotor of the crusher has become blocked and requires maintenance.

A shredder device including a feed hopper, a screw conveyor and a shredder module, wherein the screw conveyor includes a screw conveyor shaft driven by a screw conveyor motor unit and having a screw conveyor flight formed thereon, and the shredder module includes a cutting drum having cutting openings formed therein, and a main screw rotatably arranged in the shredder module and having a main screw shaft, which is driven by a main screw motor unit, and a main screw flight which is formed thereon and passes over the cutting openings. The shredder device enables a higher cutting capacity. The main screw shaft is coaxially enclosed by the screw conveyor shaft inside the feed hopper up to the shredder module.

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.

A meat grinder has a motor assembly and a grinding assembly. The motor assembly has a motor. The motor has an output axle having an annular abutting surface. The grinding assembly is securely connected with the motor assembly and has a grinding tube, a threaded rod, a blade, and an extrusion panel. The grinding tube is connected to the casing of the motor assembly and has an annular connecting base. The threaded rod is rotatably mounted in the grinding tube and has a connection segment. The connection segment is mounted through the connecting base, is connected with the output axle of the motor, and is stepped in section to form an annular abutting shoulder. The abutting shoulder is formed around the connecting segment and abuts the annular abutting surface of the output axle.

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.
