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. This causes the cutter and the holding element to cooperate to cut through the skin with a shearing action, thereby improving the ability of the device to remove completely the vent. When grooves are used to roughen the face surface, the grooves form folds within the skin. Such folds further improve the ability of the cutter to slice through the skin of the animal and thereby completely cut out and remove the orbicular muscle.
