    Abstract: A poultry processing machine including a distribution housing, a rotating dome and a truncated conical surface outwardly of the dome for the distribution of quarter legs to several processing units. Gates control the admission of the pieces to the processing units. The processing unit includes a converging inlet within which horizontal extending bars are positioned to allow the smaller end of the piece to drop downwardly into the unit. A rotatable circular blade and traction wheels draw the piece downwardly along with the operation of vacuum from a rotatable cutter. A passageway concentrically arranged within the cutter receives the bone of the quarter leg and vacuum drawn through the rotatable cutter draws the piece downwardly. A spreading surface lays the now deboned and longitudinally sliced piece into a flat slab. A skinning device having vacuum associated with a porous wheel pulls the skin away from the flesh.

  • Patent number: 6328645
    Abstract: A poultry processing machine is provided which automatically vents and opens the poultry, eviscerates the poultry, displays the poultry for inspection, and either provides a normal or radical clean out procedure to the poultry. When the poultry is being physically processed, it is maintained in a generally stationary position with respect to the surface supporting the poultry processor to provide for uniform positioning of the poultry on the conveyor. Further, the poultry is positioned in a generally horizontal position during the venting and opening, eviscerating and cleaning procedures, to facilitate removing the unwanted materials from the poultry without increasing the risk of contamination. The eviscerating station uses an eviscerating tool which includes an opening sized to receive the viscera package therethrough during the eviscerating process to prevent damage to the viscera package.

  • Patent number: 5741176
    Abstract: A device is disclosed that completely cuts out and removes the vent, including its orbicular muscle, of a slaughtered animal, such as poultry, pigs or other such animals. A centering pin nests within a holding element that has a roughened face surface for capturing the skin of the animal around the vent. The holding element is coaxial with a generally cylindrical, rotary cutter. The pin inserts into the vent and the holding element is then extended to contact the skin of the animal near the vent. The pin, which terminates in a cone-shaped knob, is then moved slightly away from the animal and toward the holding element, thereby capturing the orbicular muscle of the vent between the shoulder of the pin and a recess within the holding element. The holding element has a roughened face surface, preferably beveled, which contacts the skin and may form it into folds for easier cutting. The holding element is nested within and coaxial to the cutter; only a very small gap separates the holding element from the cutter.
