ABSTRACT:
Previously eviscerated birds are moved on an overhead conveyor in series to the lung extractor and neck breaker, with each bird moving into a poultry processing module (31). The lung extractor tube (48) moves downwardly to engage the lungs and the visceral cavity of the bird. Suction applied to the extractor tube through the suction tube (41) and air transfer block (65) causes the lungs to be extracted from the bird. When no bird is present in one of the stations of the overhead conveyor, the extractor tube is prevented from moving downwardly by the hooks (59), thereby avoiding the pulling of a vacuum through the system. When a bird is present on the shackle, the bird engages and pushed the hooks out of the way so that the extractor tube can properly function. A neck breaker (35) is also part of each poultry processing module, and the cleaver (85) is moved by cam roller (89) and cam track (90) up into engagement with the neck of the bird to break the spinal column.
