摘要： A method and device for separating the legs from a carcass of slaughtered poultry in which the carcass is positioned on the rear side, legs pointing upwards, relative to the cutters, a groin incision is made between each leg and the carcass at the side of the leg facing the carcass, and each leg is dislocated at the hip joint by pressing out each leg relative to the carcass. After dislocating the hip, a caudal hip incision is made in the remaining tissue connection between each leg and the carcass, after the two parts of each dislocated hip joint are moved a certain distance apart by applying a force acting on the hip joint ball of each hip joint, pushing the hip joint ball away from the hip joint socket prior to making the hip incision, and the legs are pulled off the carcass, essentially in the lengthwise direction of the back bone and away from the tail part.

摘要： In a separating device, the heart, lungs and liver are separated from the viscera of a slaughtered bird by conveying these organs, including the gall-bladder, connected to the bird, essentially parallel to the path of the bird with a helical roller. First the heart and lungs are separated from the liver by cutting through the tissue connecting the heart and lungs, and the liver. Next, the liver is separated from the remainder of the viscera by increasing the distance between the liver and the gall-bladder, and cutting through the tissue connecting the liver and the gall-bladder.

摘要： An elongated washer for cleaning the inside of slaughtered, eviscerated poultry, comprising a spraying element to which cleaning liquid can be fed, and radially projecting parts, running mainly in the lengthwise direction, being disposed near the spraying element, which parts are provided with sharp projections. Preferably, the sharp projections run in the lengthwise direction. The projecting parts are advantageously plate-shaped and the radial dimensions thereof, viewed in the lengthwise direction, decrease from a central part towards both ends. In a method for cleaning birds using the washer the spraying element and the projecting parts are inserted through an opening near the anus of the bird and are moved in the direction of and through the neck part.
