  • Patent number: 10010085
    Abstract: In a hollow cylindrical housing which stores a coolant, a feeding device having a rotating shaft and spiral screw vanes fixedly installed on the periphery of the rotating shaft is provided. At least one first diffusion nozzle is provided in each pitch of the screw vanes on the inner wall of the housing. A pair of second diffusion nozzles are provided for every pitch of the screw vanes on the outer periphery of the rotating shaft respectively at different positions in the axial direction of the rotating shaft and at mutually opposite positions in the circumferential direction of the rotating shaft. The first diffusion nozzles are supplied with wash water through a high-temperature water piping provided on the upper outside of the housing, while the second diffusion nozzles are supplied with wash water through a channel formed in the interior of the rotating shaft.

  • Patent number: 7335095
    Abstract: A wing separation apparatus and method for separating wings from a breast part of poultry having its breast bone removed can handle a wide variety of poultry sizes. The breast part is supported at its left and right arm pits on a pair of shafts with the left and right arm pits positioned substantially perpendicular to the shafts. Left and right guides positioned adjacent to the shafts position the tendons at the arm pits for cutting. The guides maintain the posture of the wings and gradually applies pressure against the breast meat to position the tendons for cutting. Left and right rotary blades disposed adjacent to the guides cut the tendon near the guides, thereby separating the wings from the breast meat.
