  • Publication number: 20150133040
    Abstract: The invention relates to a method for operating a poultry defeathering apparatus, where a drive mechanism is used for rotating a plurality of picking heads of a picking bank and to such a picking bank. Each picking head is mounted at an outer side of a cover member on an axle projecting through an opening in the cover member and supported by a bearing. The drive mechanism is arranged on an inner side of the cover member opposite the picking heads. To protect the drive mechanism from deterioration, a gas or air is caused to flow along an inlet path on the inner side of the cover member and onwards to the drive mechanism. The gas or air has a lower relative humidity than the air surrounding the picking heads, when the apparatus is in operation, thus ventilating any moisture entering the picking bank away.

  • Patent number: 8986079
    Abstract: The invention relates to a poultry defeathering apparatus and to a picking row for use in such an apparatus. The picking row comprises an elongate support part with a front side surface, a back side surface, a two interconnecting side surfaces interconnecting the front and back side surfaces. Said side surfaces extends in parallel to a length axis of the support part and a plurality of picking heads are arranged on the front side surface. At least one of the interconnecting side surfaces is convex, preferably being curved with a radius of curvature corresponding to half the height of the support part. In the apparatus, two or more picking rows are arranged side-by-side with the picking heads facing in substantially the same direction such that interconnecting side surfaces of neighboring picking rows face each other. In such a pair of interconnecting surfaces, at least one of them is convex.

  • Patent number: 7465224
    Abstract: An apparatus and method utilizing multiple tiers of pinch rollers that are vertically stacked one beneath the other, where each tier is designed to receive a wing portion and convey the wing portion from one start end of the roller pair to the distal opposing exit end along the line of engagement of the roller pair. The apparatus is designed with channeling chutes proximately adjacent each exit end for each roller pair tier. The channeling chute is position to receive the wing portion as it falls off the exit end and further has a vertically oriented channel to direct the falling wing to engage the start end of the roller pair below.

  • Patent number: 4980948
    Abstract: A hide is pulled from the sides of a suspended livestock carcass by gripping the hide with two grippers in the belly area, and pulling the grippers and the hide toward the back of the carcass. The pulling direction is changed by supporting the pulling devices on transversely movable carriages which are moved toward each other during the pulling action. The transverse movement enables the grippers initially to reach farther around the belly to grip the hide, and finally to pull farther toward the spine.
