Abstract: The gizzard with crop and other viscera attached thereto are retrieved from a cavity of a bird on an overhead conveyor system, and with viscera hanging from the gizzard, the gizzard is moved over a cutter whose elements define an open ended cutting path which severs the viscera from the gizzard. The gizzard is placed on a double chain conveyor with its opening facing rearwardly, and the conveyor carries the gizzard to a cutter which cuts through from the rounded end toward the opening of the gizzard and urges any hard objects in the gizzard toward the opening of the gizzard. The gizzard is placed on a pair of counter rotating helical toothed peeler rolls with a gap formed in the teeth of at least one of the rolls along at least some of the length of the roll, and a flow of air is induced between the rolls to urge the gizzard in contact with the rolls.
