  • Patent number: 5888131
    Abstract: An extrusion attachment for sausage making machines have three connection tubes with the inner tube defining a first passageway, the space between the inner and intermediate tubes comprising a second passageway, and the space between the outer tube and the intermediate tube defining a third passageway. The diameter of the inner tube is small so that meat emulsion passing into the inner tube is subjected to a higher pressure than that of the pressure in the second passageway. The lower pressure meat material in the second passageway is thinly coated on the strand of the high pressure meat material extruded from the inner tube. A thin layer of collagen material is extruded from the third passageway for deposit on the outer surface of the meat layer extruded from the second passageway.

  • Patent number: 5843504
    Abstract: The sausage strand is extruded onto a belt and carried through a brine shower system for about 40 seconds. The brine is sprayed through nozzles onto the sausage while traveling on the belt. The sausage is turned several times during the shower to insure even brine distribution. The conveyor speed is controlled to match the speed of the extruder thereby preventing stretching of the product as it is being extruded. The conveyor provides exact motion control of the sausage rope and the dwell time in the brine shower can be exactly regulated. Since the conveyor system is open it lends itself to easy cleaning and visual inspection. The conveyor consists of a frame which supports the conveyor system, the brine shower system, air knives and the infrared heater. The brine shower system is composed of a drip pan, a brine tank, a centrifugal pump and a plumbing/brine distribution network. The centrifugal pump conveys the brine from the tank through the brine distribution network.

  • Patent number: 5813906
    Abstract: A wall panel on a sausage encasing machine has a plurality of apertures with corresponding indicia marks indicating the direction of the apertures. The apertures match sizes of outside diameters of sausage stuffing tubes usable with the machine. This permits the operator to know that a given aperture has a corresponding given diameter. When the casing has been chosen for a sausage run on a particular machine, the operator selects a stuffing horn of a diameter that he or she believes to be appropriate for the casing being used. If a stuffing tube having a diameter of 0.576 of an inch is required, the operator takes the tube that he or she has selected and inserts it through the aperture on the machine that has a 0.576 inch indicia mark adjacent thereto. If the stuffing tube in the operator's hands is loose in the aperture selected, or if it will not even go into the aperture selected, the operator will know immediately that the wrong stuffing tube has been selected.
