Abstract
A method and a device for boning a leg or a part thereof of a slaughtered animal. Prior to the removal of the meat from the leg or the part thereof, an incision is made through a tendon at the position of the condyle of the tibia in the ankle joint. During scraping of meat from the lower leg, the lower leg is retained by a lug which engages in the canalis tendineus. Prior to or during the boning operation, the kneecap of the leg is pressed through an opening of a stop element, following which the kneecap projecting from the opening is removed.
Claims20
A method for boning a leg or a part thereof of a slaughtered animal, in particular a bird, comprising the steps of:
- suspending the leg or a part thereof by a tibia;
- fixing the leg or the part thereof in a position below the knee joint in a direction transverse to a longitudinal axis extending between the ends of the tibia, relative to a point of suspension of the tibia;
- and making at least one tendon incision near the position of a condyle of the tibia and then removing the meat from the leg or the part thereof, wherein the tendon incision is made through a tendon near the ankle joint.
A device for boning a leg or at least a part thereof of a slaughtered animal, the device comprising suspension means for carrying at least the leg or the part thereof by a tibia;
- fixing means for fixing the leg or the part thereof in a position below the knee joint in a direction transverse to a longitudinal axis extending between the ends of the tibia, relative to the suspension means;
- and means for removing the meat from the leg or the part thereof, wherein the suspension means includes a suspension opening which has smaller dimensions than the condyle of the tibia, and wherein cutting means adapted for making a tendon incision above the suspension opening of the suspension means are provided.
A device for processing a leg or a part thereof of a slaughtered animal, in particular a bird, having suspension means for carrying at least the leg or the part thereof by the ankle joint, and means for processing the leg or the part thereof, wherein the suspension means comprise an interacting lug and stop, which lug is adapted for engaging in the canalis tendineus of the lower leg, and which stop is adapted for supporting the lower leg at the opposite side.
A method for removing the kneecap from a leg of a slaughtered animal, in particular a bird, prior to or during the boning of the leg, the method comprising the steps of:
- passing the kneecap into an opening of a stop element, the opening being sized and shaped to prohibit passage of the bone therethrough;
- and moving a separating device alone the stop element between the kneecap and the bone to separate the kneecap therefrom.
A device for removing the kneecap from the leg of a slaughtered animal, in particular a bird, prior to or during the boning of the leg, the device comprising:
- support means for supporting at least a part of the leg connected to the kneecap;
- a stop element defining an opening into which the kneecap is passed, and a kneecap removing means for removing the leg's kneecap.
A method for removal of the kneecap from a leg of a slaughtered animal, in particular a bird, said leg comprising at least an upper leg and a lower leg, in which the upper leg bone or the lower leg bone is first removed from the leg, wherein the bone remaining behind in the leg is then acted upon in order to take the knee joint into a predetermined position at a predetermined point, following which the kneecap is separated from the leg.
A device for removal of the kneecap from a leg of a slaughtered animal, in particular a bird, said leg comprising at least an upper leg and a lower leg, having means for removing the upper leg bone or the lower leg bone from the leg, comprising means for positioning the bone remaining behind in the leg, and means for separating the kneecap from the leg.
