Abstract

A device and method for molding food articles of raw finely divided beef and similar tissue containing food material that is normally subject to uneven shrinkage during cooking comprising supply means for the material, a mold having a mold opening to form the articles and means for projecting the material under pressure across the mold opening from one edge thereof to fill the mold opening with pressurized material and shape said article.

Claims

1. A device for molding food articles of raw finely divided beef and similar tissue containing food material that is normally subject to uneven shrinkade during cooking, comprising:

supply means for said material;

a mold having a mold opening including a peripheral edge;

a supply passage means for supplying pressurized said material to said mold opening when said mold is in a mold filling position to form said articles, said passage having an exit at one edge of said mold opening of substantial width and a thickness that is a fraction of the thickness of said mold opening at said edge to project a thin ribbon of said food material into the mold opening for filling said opening with said pressurized material;

a closure for said exit having a width substantially equal to the width of said exit at the mold opening; and

means for movably mounting said closure on said mold plate for movement between a forward position defining a portion only of said mold opening and a retracted position defining said exit.

2. The device of claim 1 wherein said supply passage exit has a said thickness approximately one-half of the thickness of the mold opening.

3. The device of claim 1 wherein said supply passage exit has a width slightly less than the maximum transverse width of said mold opening in the region adjacent to said passage exit.

4. The device of claim 1 wherein means are provided for mounting said mold for movement relative to the said device between said mold filling position and a projected position where said mold opening is exposed for removal of the molded article therefrom.

5. The device of claim 1 wherein said supply passage exit has a said thickness approximately one-half of the thickness of the mold opening and said supply passage exit has a width slightly less than the maximum transverse width of said mold opening in the region adjacent to said passage exit.

6. A device for molding food articles of raw finely divided beef and similar tissue containing food material that is normally subject to uneven shrinkage during cooking, comprising:

supply means for said material;

a mold having a mold opening including a peripheral edge; and

a supply passage means for supplying pressurized said material to said mold opening when said mold is in a mold filling position to form said articles, said passage having an exit at one edge of said mold opening of substantial width and a thickness that is a fraction of the thickness of said mold opening at said edge to project a thin ribbon of said food material into the mold opening for filling said opening with said pressurized material, said mold comprising a mold plate having two superimposed parts having cooperating openings and peripheral edges together defining said mold opening and its said edge, one of said parts being of smaller area than the other, and there are provided means for moving said one of said parts relative to the other to a cooperating and coinciding position for determining said mold opening and to a relatively retracted position of the openings and edges of said one part relative to the other to define said supply passage.

7. The device of claim 6 wherein said parts comprise a bottom mold plate part having the mold opening therethrough and a top retractable part slidable thereon.

8. The device of claim 7 wherein said parts, when said bottom part is retracted, define said passage exit by the space between said opening in said top part and the upper surface of said bottom part.

9. The device of claim 6 wherein means are provided for mounting said mold for movement relative to the said device between said mold filling position and a projected position where said mold opening is exposed for removal of the molded article therefrom and wherein said parts, when said bottom part is retracted, define said passage exit by the space between said opening in said top part and the upper surface of said bottom part.

10. A device for molding food articles of raw finely divided beef and similar tissue containing food material that is normally subject to uneven shrinkage during cooking, comprising:

supply means for said material;

a mold having a mold opening including a peripheral edge; and

a supply passage means for supplying pressurized said material to said mold opening when said mold is in a mold filling position to form said articles, said passage having an exit at one edge of said mold opening of substantial width and a thickness that is a fraction of the thickness of said mold opening at said edge to project a thin ribbon of said food material into the mold opening for filling said opening with said pressurized material, said mold comprising a mold plate having two superimposed parts having cooperating openings and peripheral edges together defining said mold opening and its said edge, one of said parts being of smaller area than the other, and there are provided means for moving said one of said parts relative to the other to a cooperating and coinciding position for determining said mold opening and to a relatively retracted position of the openings and edges of said one part relative to the other to define said supply passage, said parts comprising a bottom mold plate part having the mold opening therethrough and a top retractable part slidable thereon.

11. A device for molding food articles of raw finely divided beef and similar tissue containing food material that is normally subject to uneven shrinkage during cooking, comprising:

supply means for said material;

a mold having a mold opening including a peripheral edge; and

a supply passage means for supplying pressurized said material to said mold opening when said mold is in a mold filling position to form said articles, said passage having an exit at one edge of said mold opening of substantial width and a thickness that is a fraction of the thickness of said mold opening at said edge to project a thin ribbon of said food material into the mold opening for filling said opening with said pressurized material, said supply passage exit having a said thickness approximately one-half of the thickness of the mold opening and located intermediate the top and bottom of the mold opening.

12. A device for molding food articles of raw finely divided beef and similar tissue containing food material that is normally subject to uneven shrinkage during cooking, comprising:

supply means for said material;

a mold having a mold opening including a peripheral edge;

a supply passage means for supplying pressurized said material to said mold opening when said mold is in a mold filling position to form said articles, said passage having an exit at one edge of said mold opening of substantial width and a thickness that is a fraction of the thickness of said mold opening at said edge to project a thin ribbon of said food material across and into the mold opening for filling said opening with said pressurized material, said mold opening having a curved periphery adjacent to said supply passage and said supply passage exit having a curvature adjacent to said mold opening that substantially coincides with the curvature of said mold opening; and

a closure for said exit having a curvature adjacent to said mold opening that is greater than the curvature of the corresponding adjacent portion of said mold opening peripheral edge.
