  • Patent number: 6579164
    Abstract: The invention concerns a method for removing skin from the bodies of animals, preferably of fowls, and a device for implementing said method. Known devices comprise skin-removing rollers, designed to enable height adjustment via a control cam. Said devices, however, have the disadvantage of not enabling the rollers to be accurately positioned on the bodies of animals of different shapes, in particular on bodies with curves. The invention aims at supplying a device and a method ensuring optimal positioning enabling the skin to be removed without damage. This is achieved by the fact that the inventive device comprises skin-removing rollers with two degrees of freedom, thereby enabling said rollers to be optimally positioned, independently of the size of the animal body.

  • Patent number: 5482501
    Abstract: An apparatus for removing the skin from an animal carcass. The apparatus comprises a cable, a two stage ball, and a skinner plate. The specially shaped two stage ball has a larger lobe and a relatively smaller lobe and a neck connecting the two lobes. To begin the skinning process, cuts are made in the deer's skin, or hide, and a portion of skin behind the deer's neck is pulled back. The skinner plate is placed on the raw side of the hide. The relatively smaller lobe of the two staged ball is pushed through an aperture in the skinner plate from the hair side of the hide. The cable is then tightened around the neck of the two stage ball, thereby cinching the hide to the two stage ball. A pulling force can then be applied on the cable and the skin peeled from the animal carcass.

  • Patent number: 5397263
    Abstract: A method is disclosed for the humane slaughter and efficient processing of ratites, for example, ostrich and emu, which are generally large, heavy, and hostile animals. The method envisions transporting ratites from station to station in succession within a facility via a rail system in order to process them on a mass scale. Initially, each ratite is rendered unconscious by an electrical discharge. The ratites are then hung in an inverted position on the rail system. The ratites are killed by lacerating the arteries in the neck and also the windpipe. The head of each ratite is removed and useful parts are extracted. Next, the ratites are de-feathered and skinned. The viscera of each ratite is removed. The gizzard, heart, and liver are extracted for further processing. Finally, the edible meat products are removed from each ratite and are processed for human use.

  • Patent number: 5350334
    Abstract: A meat skinning machine has a frame, an elongated skinning blade with a cutting edge, a rotatable gripping roll positioned adjacent the blade, and a motor operatively connected to the gripping roll. The skinning machine is also provided with a pivotal deflector plate for deflecting a meat product upwardly as the product is fed past the blade. The angle of the deflector plate is adjustable to accommodate different meat products and different operators. In one embodiment, the distance between the deflector plate and the skinning blade is also adjustable. The upward deflection of the meat product allows the product to be flipped forwardly to a position in front of the skinning blade for additional feeding past the skinning blade, without the operator reaching across the skinning blade to pick up or grasp the meat product.

  • Patent number: 5336124
    Abstract: A method and apparatus for skinning while protecting the hide and carcass of game animals while the game animal may be held in a horizontal position at ground level. The apparatus includes a head harness for connection of the head of the game animal to a stationary object. Also included is a skin remover which is attachable to the skin of the animal just below a neck incision and is also attachable to a vehicle bumper. A wrap-around game bag locatable beneath the game during the skinning process ensures that dirt and debris are kept away from the game during the skinning process. The method of skinning includes attaching the head of the game to a stationary object, attaching the skin remover to a vehicle and then applying force with the vehicle to the skin of the animal while the animal remains attached to the stationary object. Just before the skinning occurs and when tension is maximized, the bag is located in its open orientation beneath the game animal.

  • Patent number: 5269722
    Abstract: A method for mechanically detaching the meat from the bodies of slaughtered poultry in the form of fillets is performed with a starting product in the shape of a so called "front-half", i.e. a body portion obtained by a cross-section made obliquely through the poultry body. From this body portion the pelvis has been severed together with the legs, and by a further step the wings have been severed. The treatment in individual processing steps, the performance of which is limited to very narrowly restricted working areas by means of tools which can thus be adapted without compromise to the anatomically conditioned circumstances. Moreover, the sequence of the processing steps is selected such that the increasing destabilization of the poultry body is controlled with each processing step so that the respective subsequent working steps are influenced in a minimum manner possible. The result is a high yield in fillet meat of excellent quality.

  • Patent number: 5267890
    Abstract: The present invention relates to a device for lifting the skin and loading a poultry part into a skinning machine and, in particular, for loading a poultry breast fillet into a poultry breast fillet skinning machine. In the preferred embodiment, a pair of endless loop link chains travel around a path defined by respective pairs of vertically rotating sprocket wheels. The forward sprocket wheels are located at a slightly lower elevation than the rear sprocket wheels. Each of the links in the two link chains contains an outwardly projecting gripping finger. As the links pass over the sprocket wheels the gripping fingers tend to separate at their outer ends. As the links travel along the straight segments between the sprocket wheels, the gripping fingers tend to assume a more closely spaced relationship which pinches folds of skin on the poultry part.
