Manually segmenting animal carcasses into primary cuts involves an enormous amount of manual labor and attendant expense. However, known automated systems for segmenting carcasses cannot match the accuracy of expert butchers. The apparatus for segmenting animal carcasses disclosed herein provides an imaging station having a vision system that determines parameters of the interior and/or exterior of the carcass. Using these parameters, a computer determines a cutting path or a plurality of cutting paths for segmenting the carcass. A mounting vehicle, which securely holds the carcass, transports the carcass from the imaging station to a cutting station. In the cutting station, electrically controlled cutting implements, such as high-pressure water jets or lasers, segment the carcass along the determined cutting path or paths.

In a method for the processing of fish, poultry or other meat products being conveyed in a plurality along a processing line, components which are to be excluded from consumption are separated and edible products obtained as a result for consumption are checked with an automatic inspection device for residues left behind. Separation takes place in such a way that, in the case of a number of edible products, minimized residues of at least one kind are deliberately permitted and induced for further processing of the edible products, in particular to optimize the edible product recovery. The automatic inspection device is adjusted to detect the minimized tolerance residues, and inspected edible products with and without the tolerance residues are separated from each other. In an apparatus for carrying out the method, a separating device with at least one separating tool is designed in such a way that, in the case of a number of edible products, minimized tolerance residues of at least one kind are left behind for further processing of the edible products, and the inspection device is connected to a separator device which distinguishes edible products with and without residues according to the inspection results and discharges them separately from each other.

A grading system (10) for grading marine animals such as fish (12) by size includes a receptacle (14) for holding a volume of water (16) and the fish (12). The receptacle (14) includes a landing (18) through which fish can enter and exit the receptacle (14). A grader (20) is supported to rotate through the water (16) about a horizontal axle (22). The grader (20) includes a first panel (24a) which is provided with a plurality of openings (26a) in the form of gaps between parallel radially extending rods (28). The panel (24a) has an outer peripheral edge (30) constituted by two radial edges (32a) and a lateral outer edge (34a) extending between the radial edges (32a). The outer peripheral edge (30) contacts or is sufficiently close to an inside surface (36) of the receptacle (14) to prevent the passage of fish (12) between the edge (30) and an inside surface (36) of the receptacle (14). As grader (20) is rotated in a clockwise direction (D) about the axle (22) to a first grading position where the lateral edge (34a) is adjacent the landing (18), the panel (24a) sweeps through the receptacle. The fish which are sufficiently small are able to pass through the openings (26a) leaving the larger fish in front of the panel (24a). When the grader (20) reaches the first position, the only fish (12) in advance of the panel (24a) are those which are too big to pass through the openings (26a). These are now directed through the landing (18) out of the receptacle (14).
