Claims
- 1. An extrusion attachment for sausage making machines, comprising,
- an inner hollow elongated restrictor tube having an intake and a discharge end, and having a fixed diameter,
- an inlet coupling secured to the intake end of said restrictor tube and having a bore therein of a greater diameter than the fixed diameter of said restrictor tube and being in communication therewith,
- an outlet port coupling on the discharge end of said restrictor tube and having a bore therein with a diameter greater than the diameter of said restrictor tube,
- a second tube concentrically mounted around said restrictor tube and having an inner diameter spaced from an outer diameter of said restrictor tube to create a first passageway therebetween,
- a hollow elongated casing concentrically mounted around said second tube, and adapted to receive meat emulsion from said restrictor tube and said first passageway,
- said inlet coupling and said second tube being connectable to a source of meat emulsion under pressure,
- said first passageway being of sufficient size that meat emulsion moving therein will maintain a meat emulsion pressure substantially the same as the pressure from said meat emulsion source and less than the meat emulsion pressure in said restrictor tube,
- said second passageway having a narrowed discharge channel surrounding the discharge end of said restrictor tube whereby meat emulsion exiting the second passageway will provide a thin layer of meat emulsion around the surface of meat emulsion exiting said restrictor tube.
- 2. The device of claim 1 wherein said inlet coupling and said second tube are connectable to the same source of meat under pressure.
- 3. The device of claim 1 wherein said inlet coupling and said second tube are connectable to a different source of meat under pressure.
- 4. The device of claim 1 wherein tube stabilizer elements are located around said restrictor tube and engaging the inner diameter of the second tube to support said restrictor tube within said second tube and to maintain the restrictor tube and said second tube in concentric relationship.
- 5. A method of manufacturing a sausage product comprising,
- extruding a strand of meat emulsion through an elongated restrictor tube at a high first pressure,
- coextruding a first layer of meat emulsion through a second tube at a lower second pressure which is lower than said first pressure, with said second tube being concentrically positioned and in a spaced position with respect to said restrictor tube so that said first layer is deposited on said strand of meat emulsion,
- said first layer being deposited on said sausage strand in a common restricted space wherein the first layer and the sausage strand are subjected to a lower pressure than said high first pressure, wherein rapid expansion of said first layer is diminished to reduce smearing of said sausage strand.
- 6. The method of claim 5 wherein meat particles in said first layer are compressed before said first layer is deposited on said strand.
- 7. The method of claim 5 wherein said first pressure is approximately 200 psi and said second pressure is approximately 60 psi.
- 8. The method of claim 5 wherein said first pressure is at least double that of said second pressure.
- 9. The method of claim 5 wherein said first pressure is at least triple that of said second pressure.
- 10. The device of claim 1 wherein said casing is comprised of one of the following materials: cellulose, collagen, or natural casings.
- 11. A method of manufacturing a sausage product comprising,
- extruding a strand of meat emulsion through an elongated restrictor tube at a high first pressure,
- coextruding a first layer of meat emulsion through a second tube at a lower second pressure which is lower than said first pressure, with said second tube being concentrically positioned and in a spaced position with respect to said restrictor tube so that said first layer is deposited on said strand of meat emulsion; and
- depositing said strand within an elongated hollow casing material on said second tube.
