  • Patent number: 10757948
    Abstract: When stunning animals e.g. by CO2-stunning aversive reactions may be seen among the animals as a reaction to the high concentration of CO2. To avoid the aversive reactions animals can be pre-stunned before being final-stunned and perhaps killed or slaughtered when stunned. Pre-stunning of animals may be performed with a combination of gas for pre-stunning comprising at least air and/or O2 together with CO2 e.g. in a concentration below 40%, at least air and/or O2 together with N2O, or at least air and/or O2 together with N2O and CO2, where CO2 may bi in a concentration below 40%. For larger animals such as pigs pre-stunning is performed for less than 60 seconds. A stunning system may comprise means for pre-stunning of animals before performing a final-stunning and may include gas storage for re-use of the pre-stunning gas.

  • Patent number: 7798890
    Abstract: In poultry slaughterhouses, birds arrive in batches. Birds are delivered in holders (2), are unloaded and are connected to carriers (14). The birds are then introduced into the slaughterhouse and slaughtered, after which further processing take place. The supply is variable over the course of time. However, the slaughtering is a continuous process. The present invention evens out the supply variability, so that a uniform stream of birds which is well matched to the continuous process in the slaughterhouse is obtained. A conveyor device (8, 9) having a controllable speed is positioned between the point at which the birds are unloaded from the holders and the point at which the birds are connected to a carrier. The speed of this conveyor device is controlled in such a manner that the number of birds which leaves the conveyor device is substantially uniform. It is also possible to control the speed of unloading.

  • Patent number: 5340355
    Abstract: Apparatus is provided for orienting birds, which are applied by a belt conveyor, with their heads in the direction of conveyance. The apparatus comprises two positioning means located alongside each other and rotating around a vertical axis defining therebetween a passage for the birds to be oriented. At the passage, the one positioning means has a circumferential velocity directed in the direction of conveyance of the conveyor and the other positioning means has a circumferential velocity directed opposite to the direction of conveyance. Further, auxiliary means are provided for supplying the birds to the positioning means facing with their head or facing with their tail in the direction of conveyance.

  • Patent number: 5186677
    Abstract: Stunning of animals to be slaughtered at slaughterhouses takes place by exposing the animals for a sufficiently long period of time to an anaesthetic atmosphere, such as an atmosphere of carbon dioxide. A number of animals is first driven into a transport box (2b) which has been placed in a filling area at the slaughterhouse. Then a filled box is transported to a waiting area for boxes (2c), and from this waiting area a box is taken when needed and led through a stunning area (3) filled with the anaesthetic atmosphere, such as an oblong pit with room for 2-15 boxes (2d), which are led in one after another. The boxes (2f) with stunned animals are emptied of animals to be slaughtered, which are chained, whereas the empty boxes (2a) are returned to the filling area for renewed use. The removal of a box (2c) from the waiting area and the supply to the stunning area (3) are controlled by the current slaughtering speed and the number of boxes (2d) in the stunning area.

  • Patent number: 5134971
    Abstract: A conveyor for supporting live fowl to be inoculated, iseminated, debeaked, or to have another operation performed on them. The conveyor includes a base, a pair of spindles mounted to the base, one at each of opposite ends, and a generally horizontally-disposed moving conveyor surface supported by the base. The conveyor surface is defined by an endless web encircling the spindles and is intended to receive thereon fowl which are to have an operation performed on them. The conveyor also includes apparatus for holding each bird in a defined position on the conveyor surface, including a pair of elongated, generally-parallel members spaced upward from the conveyor surface to define a slot therebetween. The elongated members are disposed such that the vertical distance between them can be varied.

  • Patent number: 5129857
    Abstract: When birds are placed upright on the interior surface of an open-ended, non-vertical rotating drum, the birds turn, regardless of their initial orientation, so as to face "uphill" in the drum. The birds leaving the drum are all found to have the same orientation, and thus can be more easily hung on shackles.An apparatus for performing the method comprises a frame, bearings connected to the frame, an open-ended drum supported for rotation about its longitudinal axis by the bearings, means for rotating the drum about its axis, means for depositing a series of birds on the interior surface of the drum, at a first end of the drum as it rotates, and means for receiving birds exiting from a second end of the drum. The drum preferably declines from the first end toward the second at a depression angle of about 15.degree..

  • Patent number: 5009191
    Abstract: Animals such as pigs which are to be slaughtered at slaughterhouses are unloaded from the transport truck and driven into pens and stalled in these for some time, until they are driven out of the pens and over to a stunning apparatus. The pigs of a supplied lot to the slaughterhouse, or part of the supplied lot, are treated as a separate unit during one or more of the above-mentioned stages of treatment, which means that pigs of a unit are to be constantly kept separated from pigs belonging to other units. Each unit may comprise e.g. 15 pigs. The treatment of the animals in units reduces their aggressions, and their well-being is increased, which will result in a lower incidence of rind damages, blood splashings and deviant meat quality of the carcasses. A system for stalling of the pigs includes a number of oblong pens (1), which are placed next to each other. Each of the pens has an entrance gate (6), an exit gate (8) and a driving gate (10) which is movable in the longitudinal direction of the pen.
