## Abstract

A meat grinding reclamation system is disclosed herein. The system uses a plate having a plurality of holes through which meat is processed, and a smaller number of waste material indentations that feed waste material away from the meat into separate uniform curved openings. The center of the plate is provided with a shaft opening, which allows use of a center drive shaft across the plate.

## Claims

### Claim 1

A meat grinding assembly, comprising:
a. a housing;
b. a feed screw provided at least partially within the housing;
c. a knife assembly drivably coupled to the feed screw;
d. a plate coupled to the housing; wherein the plate defines;
(i) a plurality of holes;
(ii) an indentation provided in the plate surface, wherein the indentation defines an end wall coupled to the plate surface and a bottom face coupled to the end wall;
(iii) a curved opening in communication with the indentation, wherein the curved opening defines a receiving wall coupled to the bottom face of the indentation;
(iv) wherein the plate surface and the end wall define a first angle;
(v) wherein the end wall and the bottom face define a second angle; and
(vi) wherein the bottom face and the receiving wall define a third angle.

### Claim 2 (depends on 1)

The meat grinding assembly of claim 1, wherein the plate defines a center and a perimeter and wherein the indentation does not extend to within 25% of the radial distance to the perimeter as measured from the center.

### Claim 3 (depends on 1)

The meat grinding assembly of claim 1, wherein the plate defines a center and a perimeter and wherein the indentation does not extend to within 40% of the radial distance to the perimeter as measured from the center.

### Claim 4 (depends on 1)

The meat grinding assembly of claim 1, wherein the plate defines a center and a perimeter and wherein the indentation does not extend to within 50% of the radial distance to the perimeter as measured from the center.

### Claim 5 (depends on 1)

The meat grinding assembly of claim 1, wherein the plate defines a center and a perimeter and wherein the indentation does not extend to within 60% of the radial distance to the perimeter as measured from the center.

### Claim 6 (depends on 1)

The meat grinding assembly of claim 1, wherein the plate defines a center and a perimeter and wherein the indentation does not extend to within 66% of the radial distance to the perimeter as measured from the center.

### Claim 7 (depends on 1)

The meat grinding assembly of claim 1, further comprising:
a. a supplemental indentation provided in the plate surface, wherein the supplemental indentation defines a supplemental end wall coupled to the plate surface and a supplemental bottom face coupled to the supplemental end wall;
b. a supplemental curved opening in communication with the supplemental indentation, wherein the supplemental curved opening defines a supplemental receiving wall coupled to the supplemental bottom face of the supplemental indentation;
c. wherein the plate surface and the supplemental end wall define a fourth angle;
d. wherein the supplemental end wall and the supplemental bottom face define a fifth angle; and
e. wherein the supplemental bottom face and the supplemental receiving wall define a sixth angle.
