Abstract: A meat grinder having a screw conveyor, a blade journal mounted on the screw conveyor in a rotationally fixed manner, and a cutting set. The cutting set includes a perforated disc which is supported in a stationary manner on the meat grinder housing and a blade which is mounted in a rotationally fixed manner on a supporting portion of a blade journal. The blade journal is inserted in a bearing bore of the screw conveyor. An insertion end of the blade journal protrudes from the supporting portion in a radial direction, and a stop surface is located between the insertion end and a circumferential side of the supporting portion. A fastening ring is pushed over the supporting portion of the blade journal to the stop surface and can be connected to the screw conveyor, thereby achieving a detachable connection of the blade journal with the screw conveyor.

Abstract: 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).

Abstract: 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.

Abstract: 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.
