ABSTRACT:
The machine employs a plurality of individual, pointed mandrels that are attached to a closed loop conveyor having an upper processing run and a lower return run. As the mandrels move along the upper run, they are periodically reoriented into a number of successive positions so that skin removal operations can be performed on carcasses that have been impaled on the mandrels by workers stationed at the loading end of the machine. At a first station the wings are severed from each successive carcass in an upright position with special movement of the cutters being effected to prevent overly deep cutting into the breast meat. As the carcass approaches a second station with the back up and the posterior end leading, a slit is made in the back skin down the full length of the backbone by a slitting nozzle that injects air under the back skin while it is inserted between the back skin and the meat therebeneath. As the carcass passes through a third station with the breast up and the anterior end leading, a slit is made in the breast skin down the full length of the breast skin by another slitting nozzle which injects air under the breast skin as it slips between the skin and the breast meat. Subsequently, the carcass passes through a peeling station where rods engage and pull the two loosened halves of skin down toward the legs on the upright carcass, whereupon the skin halves may be manually pulled down over the legs and off the carcass to also strip the leg skin from the carcass. Thereafter, the completely skinned carcasses are automatically ejected from the machine before the mandrels start their lower return run.
