Abstract

A rotary molding system for use in a patty forming machine and configured to mold food products and a fill plate for use within the rotary molding system are provided. A replaceable wear plate is provided which seats between a reciprocating stripper plate and a fill plate. Each plate has holes through which food product passes. A drum having mold cavities receives the food product from the fill plate.

First claim

What is claimed is:

1. A rotary molding system configured to mold food products, the rotary molding system comprising:
a stripper plate having an inlet surface and an outlet surface, the inlet surface being in communication with a feed source, the stripper plate having a plurality of holes therethrough through which food product is configured to pass;
a wear plate having a planar first surface and a planar second surface, the first surface of the wear plate abutting against the outlet surface of the stripper plate, the stripper plate being movable relative to the wear plate, the wear plate having a plurality of holes therethrough through which food product is configured to pass;
a fill plate having an inlet surface and an outlet surface, the inlet surface of the fill plate abutting against the second surface of the wear plate, the fill plate having a plurality of holes therethrough through which food product is configured to pass, each hole in the fill plate being formed by a straight wall extending from the inlet surface of the fill plate and a tapered wall extending from an outlet end of the straight wall to the outlet surface of the fill plate, wherein a central axis of the straight wall and a central axis of the tapered wall are aligned with each other; and
a drum having mold cavities into which food product is configured to be deposited, the drum being proximate to the outlet surface of the fill plate,
wherein the wear plate is releasably attached to the stripper plate and the wear plate is releasably attached to the fill plate.

2. The rotary molding system of claim 1 , wherein an outer surface of the drum is cylindrical and the outlet surface of the fill plate is curved.

3. The rotary molding system of claim 1 , wherein the inlet and outlet surfaces of the stripper plate are planar.

4. The rotary molding system of claim 1 , wherein the stripper plate is attached to the wear plate by a plurality of retainer bars.

5. The rotary molding system of claim 4 , wherein each retainer bar includes a first recess and a second recess in communication with the first recess, the first recess being defined by a pair of planar surfaces, the second recess being defined by a curved surface, the stripper plate seating within the first recess.

6. The rotary molding system of claim 4 , wherein each retainer bar is releasably attached to the wear plate.

7. The rotary molding system of claim 1 , wherein each hole in the fill plate is formed by a wall extending from the inlet surface of the fill plate to the outlet surface of the fill plate which defines a length, and each hole in the fill plate has a uniform diameter along its length.

8. A rotary molding system configured to mold food products, the rotary molding system comprising:
a stripper plate having an inlet surface and an outlet surface, the inlet surface being in communication with a feed source, the stripper plate having a plurality of holes therethrough through which food product is configured to pass;
a wear plate having a planar first surface and a planar second surface, the first surface of the wear plate being proximate to the outlet surface of the stripper plate, the wear plate having a plurality of holes therethrough through which food product is configured to pass, wherein the stripper plate is attached to the wear plate by a plurality of retainer bars, wherein each retainer bar defines a recess into which the stripper plate seats, the stripper plate being capable of being moved in a reciprocating manner relative to the wear plate and relative to the retainer bars;
a fill plate having an inlet surface and an outlet surface, the inlet surface of the fill plate being proximate to the second surface of the wear plate, the fill plate having a plurality of holes therethrough through which food product is configured to pass, the wear plate being releasably attached to the fill plate; and
a drum having mold cavities into which food product is configured to be deposited, the drum being proximate to the outlet surface of the fill plate.

9. The rotary molding system of claim 8 , wherein each retainer bar is releasably attached to the wear plate.

10. A rotary molding system configured to mold food products, the rotary molding system comprising:
a stripper plate having an inlet surface and an outlet surface, the inlet surface being in communication with a feed source, the stripper plate having a plurality of holes therethrough through which food product is configured to pass;
a wear plate having a first surface and a second surface, the first surface of the wear plate being proximate to the outlet surface of the stripper plate, the stripper plate being movable relative to the wear plate, the wear plate having a plurality of holes therethrough through which food product is configured to pass;
a fill plate having an inlet surface and an outlet surface, the inlet surface of the fill plate being proximate to the second surface of the wear plate, the fill plate having a plurality of holes therethrough through which food product is configured to pass, the wear plate being releasably attached to the fill plate;
a cylindrical drum having an inner surface, an outer surface and mold cavities into which food product is configured to be deposited, the outer surface of the drum being proximate to the outlet surface of the fill plate; and
a platen mounted within the drum, the platen comprising a body having a plurality of passageways therethrough which are in communication with the mold cavities.

11. The rotary molding system of claim 10 , wherein the platen comprises a plurality of fins alternating with recesses, the recesses forming a portion of the passageways.

12. The rotary molding system of claim 10 , wherein the outlet surface of the fill plate is curved.

13. A rotary molding system configured to mold food products, the rotary molding system comprising:
a stripper plate having an inlet surface and an outlet surface, the inlet surface being in communication with a feed source, the stripper plate having a plurality of holes therethrough through which food product is configured to pass;
a wear plate having a planar first surface and a planar second surface, the first surface of the wear plate being proximate to the outlet surface of the stripper plate, the stripper plate being movable relative to the wear plate, the wear plate having a plurality of holes therethrough through which food product is configured to pass, wherein the stripper plate has twice as many holes as the wear plate;
a fill plate having an inlet surface and an outlet surface, the inlet surface of the fill plate being proximate to the second surface of the wear plate, the fill plate having a plurality of holes therethrough through which food product is configured to pass, the wear plate being releasably attached to the fill plate; and
a drum having mold cavities into which food product is configured to be deposited, the drum being proximate to the outlet surface of the fill plate.

14. A rotary molding system configured to mold food products, the rotary molding system comprising:
a stripper plate having an inlet surface and an outlet surface, the inlet surface being in communication with a feed source, the stripper plate having a plurality of holes therethrough through which food product is configured to pass;
a wear plate having a planar first surface and a planar second surface, the first surface of the wear plate abutting against the outlet surface of the stripper plate, the stripper plate being movable relative to the wear plate, the wear plate having a plurality of holes therethrough through which food product is configured to pa
