Mincer with at least one rotary mincing tool

Abstract

A mincing machine comprises a housing having an inlet for the material to be minced and a discharge for the minced material includes a mincing passage between the inlet and the discharge with a rotatable shaft therein having at least one rotatable mincing tool affixed thereto for rotation therewith in the mincing passage and including a centrifugal disc affixed to the shaft for rotation therewith at the entrance to the mincing passage which has a peripheral portion with a respective groove for collecting hard objects before they move into the mincing passage. The groove advantageously comprises an annular trough-shaped formation of the disc which includes an outer radial rim portion at the front end of the passage and a wall facing toward the mincing tools having a plurality of apertures therein through which the material passes for mincing. The annular groove of the disc receives any hard materials by the centrifugal action of the rotation of the disc and prevents their movement into the mincing passage where they might damage the mincing tool.
