ABSTRACT:
The evisceration process removes the entire alimentary tract, including the crop, in one operation and without damaging the tract. After the removal spoon enters the opening at the vent end of the carcass and moves along the breast bone, it swings over against the back wall of the body cavity to clamp the esophagus against the backbone at a point just below the weak region of attachment of the esophagus to the stomach. Simultaneously, a crop loosening hook enters a slit in the neck of the carcass, moves up along the esophagus into the body cavity, and intertwines with the esophagus by rotating through 360.degree.. During the time that the esophagus is clamped against the backbone by the removal spoon, the loosening hook is pulled back down along the esophagus, stripping the crop from its connective tissues and loosening the crop for withdrawal. When the removal spoon is then withdrawn up and out of the cavity, the esophagus pulls the loosened crop up and out of the carcass with the rest of the viscera.
