Abstract
An apparatus for removing the meat from an elongated poultry bone, such as a thigh piece, includes an elongated frame and a housing which defines a feed end and a discharge end. An elongated conveyor is supported on the frame and extends from the feed end to the discharge end. A hold-down rail is supported by the housing for parallel movement towards and away from the conveyor to hold the bone in engagement with the conveyor for movement thereby. A scraper is positioned to engage the meat and the bone as it passes along the hold-down assembly. A water knife is positioned downstream of the scraper. The knife is biased into engagement with the thigh piece and discharges a high pressure water stream onto the piece to peel the meat down from the bone. A plate assembly defining a slot is positioned downstream of the hold-down rail. The bone passes through the slot and is progressively wiped by the plate assembly. A cutting assembly is positioned downstream from the plate assembly for cutting the meat from the lower edge of the bone.
