  • Patent number: 6450873
    Abstract: In a method and device for carrying out at least one processing operation on a slaughtered bird which is hung by its legs, the bird is conveyed on a hook of a conveyor towards and into the processing area of a processing device in order for the at least one processing operation to be carried out on the bird. The bird is positioned in the processing area of the processing device by externally supporting the bird at at least two locations, which are selected from the group of locations which comprises the back, the sternum, the area of the clavicle, the wings and the sides of the bird. Then, the at least one processing operation is carried out in the processing device in the area of the breast of the bird. The bird may also be positioned in the processing area of the processing device by internally supporting the bird on the side of the sternum facing the abdominal cavity of the bird.

  • Patent number: 6007416
    Abstract: In a method and an apparatus for automatic removal of at least an inner fillet from slaughtered poultry or a part thereof before the connection between the inner fillets and the carcass is broken, a separation is made in the opening bounded by the clavicle and the breastbone, whereupon the inner fillets are at least partly scraped off from the carcass. In another method of filleting, the canalis triosseus is cut open in the shoulder joint, whereupon at least the inner fillets are pulled free from the carcass with the aid of the humerus. Previously, the connection between the membrane of the inner fillets and the breastbone in the region of the coracoideum is broken. For placing a front half of a slaughtered bird on a carrier, a bird is hung by its legs on a suspension element, whereupon the front half and the back half are separated from one another except for a rear connection. The front half is thereupon placed on the carrier and the rear connection is broken.

  • Patent number: 5595066
    Abstract: Method and device for preserving the meat of a slaughtered bird or a part thereof, in which the bird or the part thereof is firstly cooled in a short time until the core temperature of the meat is lower than the temperature at which heat-shortening occurs at the prevailing acidity; and next the bird or the part thereof is cooled further, in the course of which the core temperature of the heat remains higher than the temperature at which cold-shortening occurs at the prevailing acidity. During the cooling steps the surface is cooled to such a temperature that the germ counts or decay-causing and pathogenic micro-organisms remain below a predetermined value.

  • Patent number: 5549521
    Abstract: Method and device for separating one or more organs or a part thereof from a cluster of interconnected internal organs from a slaughtered animal, making use of a fixing device which is moved through an evisceration opening into the body of the slaughtered animal, in which method a part of the cluster is fixed with the aid of and relative to the fixing device, the connection between the organs and the body is broken, and the organs are taken out of the body. The fixing is maintained after the organs have been taken out of the body and until a separating operation has been carried out on one or more organs or a part thereof in a spatial orientation determined by the fixing. The fixing is achieved by clamping a part of the cluster. During the fixing, organs can be separated from the cluster of organs with the aid of guide elements, stripping elements, separating rollers, and cutting elements.

  • Patent number: 5326311
    Abstract: A method for controlling the processing of poultry in different production lines operating in parallel, wherein the control of the processing of a specific bird or a part thereof takes place on the basis of data derived from one or more observed contours of the bird or a part thereof. For purposes of the control the data may be supplemented by the weight of the bird or part thereof. In a device for carrying out the method the observation takes place with the aid of one or more radiation sources which transmit radiation rays to one or more radiation detectors, which radiation rays can be interrupted or weakened by the birds or parts thereof passing therethrough.

  • Patent number: 5312291
    Abstract: A method and device for filleting the body of a slaughtered bird, or a part thereof, the method having the following steps: making incisions in the shoulder joints while the connection between the muscles to be filleted and their wing bones remains intact; tearing away a fillet from the ribs by exerting a force which acts upon the wing concerned and is directed essentially away from the ribs; and breaking the connection between fillet and wing bone. The bird, or a part thereof, is fixed on a supporting element which is movable along a predetermined path at a predetermined speed, and which can be tilted from a neutral position, in which the shoulder side of the bird is facing upwards, to a breast position, in which the breast side of the bird is facing upwards, and to a back position in which the back of the bird is facing upwards.

  • Patent number: 5248277
    Abstract: Method and device for processing the skin of a leg of a slaughtered bird. The bird or leg is moved along in a conveyor. The skin of the leg is cut through completely or almost completely in the vicinity of the knee joint between the region of the kneecap and the region of the back of the knee, the tissue lying under the skin remaining essentially intact, by conveying the leg past a cutting device and putting it in contact therewith. The leg is supported by leg positioning elements while it is passing the cutting device. The cutting depth of the cutting means is limited by a stop which is connected to the cutting means. Provision is made for a stripping device for stripping the severed thigh skin away from the suspended leg downwards. Provision is also made for a roll-up device for rolling up the drumstick skin prior to separating the leg into a thigh portion and a drumstick.
