  • Patent number: 9675092
    Abstract: A poultry processing line is provided having a series of poultry carriers and a processing unit or processing units, wherein the poultry carriers are movable to and from the processing unit or processing units and the poultry carriers and the processing unit or processing units are synchronized to enable processing of the poultry by the processing unit or processing units. A switch is provided such that the poultry carriers and/or the processing unit or processing units are selectable between an operational position in which the poultry is processed by the processing unit or units and an inoperational or idle position in which the poultry is prevented from being processed by the processing unit or units.
    Type: Grant

  • Patent number: 8986082
    Abstract: A processing apparatus for poultry is provided. In an exemplary embodiment, the apparatus includes one or more transfer units placed intermediate of, conveying poultry from, a first line to a subsequent second line, wherein both the first line and the second line are selected from the group including a slaughtering line, an evisceration line, a chilling line, a sorting line and a cutup line. Each transfer unit is embodied with a circulating support that includes material that is magnetically conductive and transfer devices are provided with at least one magnet so as to induce eddy currents in the circulating support that counteracts relative motion between the transfer devices and the circulating support.

  • Patent number: 8062105
    Abstract: A scalding apparatus for poultry includes an overhead conveyor for moving poultry, suspended by their legs, through an immersion tank filled with scald water. A filtering device and pumping unit can be used to withdraw the scald water, clean the scald water, and reintroduce the scald water to the tank. Upwardly directed nozzles, located in the bottom of the tank, provided a stream of scald water directed up and over the poultry. A reversing guide may be provided for redirecting the scald water downwards to the poultry. The immersion tank may be divided into chambers.

  • Patent number: 7905768
    Abstract: A device for picking or plucking poultry feathers is provided that includes a sleeve-coupling and, connected or connectable thereto, a plucking plate with receptacles for plucking fingers, which sleeve-coupling is mountable on a drive-shaft for the plucking plate. The sleeve-coupling is provided with a circumferentially extending slot for receipt of a radially extending pin that is provided on the drive-shaft, and the circumferentially extending slot has an opening between the slot-extremities to allow the pin to enter and to exit the slot so as to securely mount the sleeve coupling on the drive shaft with the pin being located at one of the slot extremities.

  • Patent number: 6783451
    Abstract: The invention relates to a method and apparatus for removing faecal matter from slaughtered poultry suspended by the legs, wherein the poultry, after having been cut for bleeding, is scalded to soften the feathers of the poultry, and after having been scalded is plucked and eviscerated to provide fresh defeathered slaughtered poultry, wherein also the removal of faecal matter takes place by prior to evisceration removing not yet unloaded faecal matter from the poultry by applying a pressure load to the abdominal cavity of the poultry, and simultaneously or subsequently spraying away the faecal matter squeezed out of the poultry with water and/or air.
