Patent number: 7335095Abstract: 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.Type: GrantFiled: September 30, 2006Date of Patent: February 26, 2008Assignee: Mayekawa Mfg.
