Abstract:
A deboning device for separating bone and meat of poultry parts, said device comprising a plurality of deboning units (1) mounted along an endless chain (9), which endless chain (9) is provided to be moved in longitudinal direction along a processing path, whereby each deboning unit (1) extends in cross direction of the endless chain (9) and comprises at a first end a meat stripper disc assembly (4) with a meat stripper disc (15), which meat stripper disc (15) contains an aperture (16) for receiving the bone of the poultry part therethrough in longitudinal direction of the bone and stripping the meat from the bone, which deboning unit (1) comprises at a second end opposite said first end, a bone pusher assembly (24) for displacing the bone towards and through the aperture (16) of the meat stripper disc (15), which deboning unit (1) comprises at a side facing the meat stripper disc (15) a carrier (2) for carrying the poultry part to be deboned, which deboning device further comprises means (27) for guiding the bone pusher assembly (24) towards the meat stripper disc (15) into engagement with the poultry part, characterized in that the deboning device comprises at least one deboning position (35), which deboning position (35) comprises the means (27) for guiding the bone pusher assembly (24) towards the meat stripper disc (15), which meat stripper disc (15) is made of a flexible material, in which bone pusher assembly (24) a pusher rod (10) is slideably mounted, which pusher rod (10) has a front end (13) with a diameter that is larger than the diameter of the aperture (16) of the meat stripper disc (15), which pusher rod (10) is provided to co-operate with the means (27) for moving the pusher rod (10) to a position where the front end (13) of the pusher rod (10) is in contact with the meat stripper disc (15) and the meat stripper disc (15) is elastically deformed in such a way that part of it extends beyond the meat stripper disc assembly (4) and the bone is displaced substantially completely through the aperture (16) of the meat stripper disc (15), whereby the deboning device comprises at a position in the vicinity of and upstream the deboning position (35), a first obstruction (36) which is positioned in a direction substantially perpendicular to the processing path for stopping the bone after it has been displaced substantially completely through the meat stripper disc (15) and forcing the bone to move out of the aperture (16) of the meat stripper disc (15).
