Abstract

A grinding machine for grinding foodstuffs, such as meat or the like, includes an orifice plate at the outlet of a grinding head. The orifice plate has collection passages that discharge a mixture of soft material and hard material through the orifice plate. A separator assembly is positioned downstream of the orifice plate for separating the soft material from the hard material. The separator assembly includes a separator chamber that receives the mixture of soft material and hard material, in combination with a rotatable separator screw positioned within the separator chamber. Rotation of the separator screw functions to separate the soft material from the hard material. Soft material is discharged through perforations in the separator chamber and hard material is discharged through a discharge of the separator chamber.

Claims (10)

1. A meat grinding method comprising:

depositing meat into a grinder, the meat containing both meat and bone;

grinding the meat in the grinder thereby separating the meat into material that does not contain bone and material containing both meat and bone;

removing the material that does not contain bone from the grinder to an exterior of the grinder;

moving the material containing both meat and bone into a separator connected to the grinder without moving the material that still does not contain bone into the separator;

separating the material containing both meat and bone in the separator into additional material that does not contain bone and remaining material that still contains bone;

removing the additional material that does not contain bone from the separator to an exterior of the separator; and

removing the remaining material that still contains bone from the separator.

2. The meat grinding method of claim 1 , wherein the meat is passed through a plurality of openings and collection passages in a plate within the grinder when grinding the meat in the grinder, wherein the material that does not contain bone passes through the openings in the plate and the material containing both meat and bone passes through the collection passages.
