  • Patent number: 9668491
    Abstract: A poultry stunning apparatus and method, the apparatus including an electrical control module configured to apply a DC current to the poultry at a voltage sufficient to stun the poultry and to apply AC current to the stunned poultry at a voltage and for a period of time sufficient to immobilize and relax the muscles of the stunned poultry, while at the same time avoiding or minimizing damage to the poultry tissue. In the method, DC voltage/current is applied for initial stunning, followed by an AC voltage/current to immobilize poultry and to further relax the muscles of the stunned poultry, such that the poultry does not exhibit involuntary motions, while at the same time avoiding or minimizing damage to the poultry tissue.

  • Patent number: 9572354
    Abstract: An assembly according to the invention includes two pairs of relays, such as SSR semiconductor relays. The relays of each pair operate with the opposite direct current potentials. Direct current with the voltage of 220 V to 400 V as well as control lines are connected to the clamps of the controlled relays. The operation of the relays is controlled by means of a controller, such as a PLC programmable controller. The relays are connected to the first electrode clamp, and the other relays to the second electrode clamp. The assembly operates in such a way that the PLC controller activates the relays from the line, which simultaneously activate the flow of the direct current with the voltage of 220 V to 400 V and mutually opposite polarity. As a result of this, a difference of potentials appears on the electrode clamps.

  • Patent number: 8506366
    Abstract: Described are animal stunning apparatus and methods for inducing rapid unconsciousness and insensibility. The apparatus includes a stunning station in which a live subject animal is located in a confined position and an applicator contacts an application point on the live subject animal's head immediately overlying a frontal portion of the animal's brain and couples microwave radiation to the head. A microwave generator generates microwave energy of a suitable power level and frequency, and a waveguide directs the microwave radiation to the applicator. A switch discontinues the application of microwave radiation effecting heating of the frontal portion of the brain after a period of time sufficient to have raised the temperature of the frontal portion of the brain of the subject animal to thereby induce the unconsciousness and insensibility.

  • Patent number: 5954572
    Abstract: The invention is a current controller for use in, for example, automatic animal stunning equipment.A problem in the past has been that animal stunning equipment has not always stunned animals sufficiently humanely prior to slaughter. For example, when a short circuit has occurred and an animal is not sufficiently stunned, the animal has suffered trauma prior to slaughter. Regulations are now being introduced so as to minimise such trauma.The invention solves this problem by providing an improved Wilson mirror constant current generator which can operate in high voltage circuits, with good dynamic response, thereby ensuring the preferred current is always applied to correctly stun an animal.

  • Patent number: 5954573
    Abstract: A method is disclosed for bleeding a live fowl upon processing the fowl after severing a carotid artery of the fowl. According to the method, electric pulses are applied across the fowl promptly after the carotid artery of the fowl is severed. Preferably, the electric pulses are applied for 3 to 10 seconds upon an elapsed time of 1 to 10 seconds after the carotid artery of the fowl is severed.

  • Patent number: 5906540
    Abstract: An electronic animal stunning system is disclosed, wherein animals can be continuously stunned while being moved through a stunning passageway, and wherein the current for the stunning process utilizes a series of electrodes for sequentially contacting the animal to be stunned and providing the stunning current. In particular, a series of pivotally mounted overhead electrode paddles are provided, wherein each paddle in the series of paddles pivots when contacted by the animal's head and slides across the face of the animal's head thereby setting up an electric current through the animal's head. The present invention is particularly useful for the slaughtering of hogs.

  • Patent number: 5899802
    Abstract: An apparatus and method for automatically electrically stimulating poultry carcasses in poultry processing plants in order to tenderize the poultry meat are disclosed. Carcasses suspended by shackles from a moving processing line are transported between two preferably curved electrical conductive bars, which are positioned to apply the electrical stimulation across the breast of the suspended carcass. The carcasses may otherwise be dragged through a charged saline or water solution, or across a charged metal mesh or grill. The carcasses are subjected to electrical stimulation for by the application of an intermediate level voltage for the period of stimulation.

  • Patent number: 5820451
    Abstract: A method and apparatus for the immobilization of live hard shell aquatic crustaceans "hard shell crabs" prior to or during processing. The apparatus includes a nonconductive container containing an electrolyte solution, the quantity of said electrolyte solution being sufficient to submerge a number of live hard shell crabs to be processed; positive and negative electrodes positioned in spaced relationship within the container and being at least substantially covered by the electrolyte solution, each of said electrodes comprising a pair of parallel metal rods projecting vertically from the bottom of the container; and an electric switch means contained in a connector box, said switch means being electrically connected intermediate the electrodes and an electrical power source for allowing an operator to activate the apparatus, whereby the electrical energy supplied to the electrodes is transferred via the electrolyte solution to the submersed crabs for their immobilization.

  • Patent number: 5486145
    Abstract: A method of stunning an animal for slaughter includes the steps of providing the animal for slaughter; conveying the animal using conveying means; while conveying, causing a first current pulse having a maximum duration of 10 seconds to flow through the head and/or neck region of the animal to stun the animal; and, while conveying, causing a second current pulse to flow through the body of the animal to cause a cardiac arrest. The first and second current pulses may be applied successively or may be overlapping or partly overlapping.

  • Patent number: 5401209
    Abstract: An apparatus for stunning poultry has a conveyor moving along a predetermined path, for suspending the poultry and a compartmentalized basin defining individual compartments for a conducting liquid. The basin is positioned below a portion of the conveyor. A circuit impresses a voltage across the conveyor and each of the individual compartments. The voltages are a function of the position of each of the compartments relative to the conveyor. The voltages are variable so as to produce a current regulated signal flowing between the conveyor and each of the individual compartments when the poultry is in contact with the conducting liquid in any of the individual compartments.

  • 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.
