Abstract: To provide a deboning apparatus which can treat a " "-shaped boned dark meat composed of upper leg dark meat portion and lower leg dark meat portion, so as to decompose the dark meat into meat and bone.

Abstract: In a chicken deskinning device a pair of rollers is provided whereby one may be pivoted with respect to the other for defining a gap therebetween. The rollers terminate in a pair of blocks, each of which has an open end to allow the passage of chicken skin past the rear of the roller bearing blocks. A second set of rollers may be employed beneath the first set.

Abstract: A process and apparatus for descaling tuna fish and the like wherein the fish is at least partially cooked and then cooled to a backbone temperature of about 70.degree. to 100.degree. F. The fish is placed on a conveyor and passed through horizontally and vertically disposed brushes. Jets of water are sprayed on the fish at the point of contact of the fish and the brushes to thereby wash away the scales and skin as removed by the brushes.

Abstract: A poultry breast fillet skinner includes a table, a lower conveyor supported on the table, an upper conveyor with means to allow the upper conveyor to be pressed down toward the lower conveyor so as to firmly grip the poultry breast fillet, and a wing disposed between the upper and lower conveyors which affects the separation of the skin from the poultry breast fillet. In the preferred embodiment the separation process is assisted by a pair of openings provided on the pointed ends of the projections of the wing. Pressurized air is expelled into natural pockets formed between the skin and the meat portion of the poultry breast fillet which assist in beginning the process of separating the skin from the meat portion of the poultry breast fillet.

Abstract: A skinning machines having a gripping roll, a skinning blade, a power unit for rotating the gripping roll, and a safety circuit responsive to manual contact of the machine operator with danger zone of the skinning machine. A clutch is provided to the skinning machine is operatively connected to the gripping roll and the power source for the gripping roll. A brake is connected to the safety circuit and the gripping roll. The clutch is normally operative, and the brake is normally inoperative, whereby the brake will stop the rotation of the gripping roll when the safety circuit is activated to overcome the operative condition of the clutch. The brake includes a coiled spring that tightens on a hub connected to the gripping roll when the safety circuit is actuated. The safety circuit includes a solenoid device that releases the spring to tighten on the hub when the safety circuit is actuated.

Abstract: A method and apparatus for filleting meat from bone containing meat material wherein at least one of the knuckles of the piece of bone which passes through the meat material, is removed before the meat is stripped from the bone. Alternatively, the meat piece is cut approximately in half, resulting in two meat pieces, each including a straight or central bone section surrounded by meat with only one knuckle. Thereafter, the knuckle of the meat piece is placed into a slot of a holder and clamped by means of a piston. The apparatus includes a knife assembly on a frame movably mounted relative to the clamp, with the frame carrying first and second pairs of coacting knife members configured and positioned for defining a meat stripping opening. The meat piece is clamped with the straight or central section of bone aligned for placement within the meat stripping opening with the knife members of the knife assembly initially in proximity to the knuckle.

Abstract: The meat skinning machine of this invention comprises the conventional components of a frame with a rotatably powered gripping roll having a cylindrical peripheral surface mounted thereon. A plurality of gripping teeth are formed on the peripheral surface of the gripping roll. An elongated blade holding means is mounted on the frame and extends parallel to the gripping roll and is positioned closely adjacent thereto. An elongated blade is secured to the blade holding means, with the blade having a forward edge portion protruding from the blade holding means and terminating in an elongated sharp cutting edge. The cutting edge of the blade is closely adjacent the teeth on the gripping roll. An elongated plate is on the blade holding means either as an integral part or an attachment thereto. The plate has a forward edge and an upper surface.

Abstract: Apparatus for controlled injection of treatment solution into slaughtered animals.

Abstract: The skinner falls within the art field of machines utilized by the fish processing industry, and serves to remove the skins of non-scaly varieties such as cuttlefish, octopus and squid; operation is entirely automatic, from the entry of the fish onto an angled and tilted infeed surface right through to their collection with the skins removed.

Abstract: A poultry skinner comprises a stationary frame having a pair of chain guides attached thereto, and a pair of parallel endless chains mounted for movement upon the chain guides. The chains, driven by a motor through a Geneva drive transmission, which produces intermittent motion, carry a series of birds over a first peeling roll for removing skin from the breasts, and, after the bird is inverted, over a second peeling roll which removes the skin from the back. The bird is then automatically engaged by a fixture which supports it for further processing.Also disclosed is an improved stripper roll arrangement for cleaning peeling rolls, and a skin nicking device for cutting tendons critical to the skinning operation.
