  • Patent number: 4993110
    Abstract: A device for boning pieces of meat, such as shoulders, hams and the like, which device consists substantially of at least one set of first and second matrices (3, 4) with separating means to be carried towards one another for separating the meat from the piece of bone and a replaceable stamp (5, 6) arranged in one of each matrix, of which the elongate, if necessary folding pressure surface coming into contact with the piece of bone displays a relief, wherein in cross section the relief of the pressure surface is raised at least along the edge zones thereof, and the raising increases in those cross sections at the edge portions having a comparatively small radius of curvature, so ensuring that during pressing the piece of bone remains enclosed an even undergoes a pressure force directed lengthwise of the piece of bone.

  • Patent number: 4924771
    Abstract: The device consists substantially of a support for the meat, a holder in which hollow needles are mounted. Each of the needles communicates with an individual dosing chamber which is connected to a common supply conduit for a fluid such as a liquid or a pasty substance or the like which is to be injected into the meat. The device has a dosing chamber in the form of a cylinder which has a movable piston therein for obtaining a constant stroke volume. A driving device is arranged for bringing about relative movement between the piston and the cylinder.

  • Patent number: 4862558
    Abstract: A method and device for boning meat portions, making use of two opposite pressing elements adapted to be moved to and from each other, wherein each pressing element comprising a recess provided with inserts, along the borderline of the recess each pressing element is provided with means to separate the meat material from the bone or bones, said separating means are following substantially the contour of the bones in the meat portion, for instance the front leg or shoulder portion of a pig, said recess in at least one of the pressing elements is provided with means for locking up or pressing the or each bone piece in length-wise direction thereof and at least one of the pressing elements is provided with gripper members for gripping at least one ridge of a bone; as a result the bone is held firmly in place in a well positioned manner during the meat extracting operation.

  • Patent number: 4663804
    Abstract: A de-boning machine comprises a pair of dies which are adapted to close around a meat portion in which a bone is located such that the meat is displaced laterally from the bone in response to closing of the dies while the bone remains in tact. The dies preferably have opposite disposed de-boning faces in which a bone locating recess is formed. To reduce the likelihood of damage to the bone resulting from closing of the dies, the bone receiving recess is filled with a resiliently deformable material such as a food grade rubber. In order to separate the meat which has been laterally displaced from the bone, a cutter is provided laterally outwardly from the bone receiving recess, the cutter being operable upon final closing of the dies.
