  • Patent number: 6213864
    Abstract: Water is conserved and poultry raised for human consumption is cleaned by a viscera-removing machine that incorporates a unique nozzle member positioned adjacent a crop-removing tool. The close positioning of the nozzle to the crop-removing tool insures that contaminates are washed out of the internal cavity of the bird immediately upon crop removal. This prevents contaminates from being absorbed into tissue surrounding the internal cavity. The nozzle is mounted in longitudinal alignment with the crop-removing tool at the lowermost or leading end of a spiral rod that rotates about its axis of symmetry and reciprocates up and down as previously slaughtered poultry is delivered to a crop-removing and washing station. Each downward motion of the spiral rod causes the tool and nozzle to enter the vent of a bird and to exit at the neck opening.

  • Patent number: 6165062
    Abstract: A poultry processing machine is provided which automatically vents and opens the poultry, eviscerates the poultry, displays the poultry for inspection, and either provides a normal or radical clean out procedure to the poultry. When the poultry is being physically processed, it is maintained in a generally stationary position with respect to the surface supporting the poultry processor to provide for uniform positioning of the poultry on the conveyor. Further, the poultry is positioned in a generally horizontal position during the venting and opening, eviscerating and cleaning procedures, to facilitate removing the unwanted materials from the poultry without increasing the risk of contamination. The eviscerating station uses an eviscerating tool which includes an opening sized to receive the viscera package therethrough during the eviscerating process to prevent damage to the viscera package.

  • Patent number: 5735735
    Abstract: In a method for automatically gutting fish of the catfish species, the belly cavity is opened around the anal orifice either before or after opening the gills by severing the gullet and opening the blood stream, and the contents of the belly cavity are removed by pushing these from one of the openings of the cavity out of the other. In a machine for carrying out this method, the fish are conveyed sideways by a recessed conveyor. The belly cavity is opened in the vicinity of the anus by separating away the cartilaginous plate carrying the ventral fins. The contents of the ventral cavity are removed by a rotary body rotating synchronously with the conveyor and having tools successively arranged in a cantilevered helix around its circumference which comprise a clearing tool with scraping segments, a brush tool, a high-pressure spray device and a cutting tool for slitting open the belly cavity along its length.

  • Patent number: 5026318
    Abstract: In a method and an apparatus for gutting non-decapitated fish, in particular breeding fish such as trout, it is characteristic for the processing that the fish are conveyed with their tails leading in longitudinally aligned conveyor troughs, and the treatment of the fish comprises the processing steps of slitting the belly cavity from the anus up to the region of the belly cavity; spreading the belly flaps and tearing open of the bloodstream; collecting and sucking off the entrails; and tearing off the gullet in the area of the mouth cavity. This processing can selectively be combined with the removal of the gills. For correctly performing this process, the cutting tool for slitting the belly cavity is provided with lateral knife blades, which sever the intestine in the anal region, while the suction nozzle is designed as a clamping mechanism in order to tear off the gullet.

    Abstract: An apparatus for carrying out a method for gutting fish is provided, which comprises in combination a conveyor including a number of segments at given intervals in a direction substantially perpendicular with respect to its moving direction and operating at a given speed in a certain direction, a rotary cutter for cutting off a head of a fish placed and carried on the conveyor while the venter located within the segment leads and the head is projected from one side edge of the conveyor, a retainer for retaining the fish to be beheaded in place, a plate for forcing the dorsal region of the beheaded fish onto the conveyor by the action of a spring, a guide plate fixed at a position where it comes into engagement with a cut end of the beheaded fish forced onto the conveyor by the plate, and a guts squeezer member formed of an elastomer adapted to be forcedly slid over the venter of the fish from the anus toward the cut end, the fish being now in engagement with the fixed guide plate and forced by the plate.

  • Patent number: 4976010
    Abstract: The present invention is directed to a method and apparatus for the improved and more rapid cleaning of, or the removal of the viscera or the so-called "guts" of dead fish without the need for the cutting open of the fish in order to get into or have access to the body cavity of the fish. The device is typically attached to a common garden hose type of water nozzle and is inserted into the anus of the bait fish. With the application of water pressure the intestines/viscera are forced out of the mouth of the dead fish. No cutting and stitching is required and the fish is substantially not altered in appearance thus not affecting its usefulness as a bait fish.
