Abstract: In a machine for gutting fish, particularly trout and salmon, wherein the fish is guided through the machine in swimming position, and wherein the machine comprises tools for cutting the fish's belly, removal of the intestines, cutting the abdominal membrane covering the blood rim, and removal of the blood rim, one has aimed to provide a tool for cutting said abdominal membrane such that the blood rim is not torn up, and such that the rear part of the abdominal cavity of the fish is not damaged. This is achieved in that the cutting tool for the abdominal membrane consists of a rotary knife disc (4) having a V-shaped circumference portion (4', 4"). When such a knife disc (4) approaches the rear edge of the abdominal cavity of the fish, the fish will be raised by the V-shaped circumference portion of the knife disc, so that one avoids that the knife discs causes damages in the rear part of the abdominal cavity of the fish.

Abstract: A method and apparatus for processing gizzards uses a gizzard splitter, a gizzard defatter and a gizzard peeler. The splitter includes upper and lower conveyors which define pockets for receiving an individual poultry gizzard. The pockets retain the gizzard as it is pushed over a rotating probe. The rotating probe includes a nipple-shaped head which washes foreign matter from the gizzard. The conveyor pockets also pass the gizzard by a rotating knife which slits the gizzard. The splitter includes a spray system for cleaning the upper and lower conveyor assemblies. The gizzard defatter includes a plurality of stationary picker fingers and a rotating frame having picking fingers mounted thereon. The picking fingers engage the gizzards removing fat and other debris. The peeler includes a plurality of sets of helically cut intermeshing gizzard peeler rolls or rollers and a rotating auger. A plurality of pins are positioned on the auger. The pins contact the gizzards and flip them on the gizzard peeler rollers.
