４５号公報記載のものがある。[Conventional Technique 1 The conventional method for surface treatment of frozen fish bodies is performed artificially; first, the frozen fish body is cut in the direction of the lateral line with a band saw and divided into two parts), and then the body is cut into two parts with a band saw in the direction of the dorsal fin. Cut each piece in the direction of the pelvic fin, and finally the frozen fish body is cut into 4 pieces.
The frozen fish body is divided into 4 parts (four-division process), and then the blood, etc. of the divided frozen fish is cut with a T-shaped cutter to remove the blood, etc.), and the surface of the frozen fish is cut with a T-shaped cutter in order to increase the commercial value of the frozen fish. The surface is treated by cutting and cutting (skin removal process). As one of the means to automate some of these artificial processes, for example, Japanese Patent Application Laid-Open No. 62-2659
There is one described in Publication No. 45.

形成すれば良い。Next, the frozen fish S is guided by the ■-shaped guide 7 and cut by the drum cutter 91.91 of the second rotary blade device 9.9 located above the side surface, and the dorsal fin of the frozen fish S is cut.
The pelvic fins are removed. When cutting dorsal fins and pelvic fins, the drum cutters 91 and 91 are urged toward the frozen fish S side by a spring (not shown), so the old drum cutter,
9■ moves along the curve of the frozen fish body S, and the dorsal fin and pelvic fin are cut while following the frozen fish body S. The frozen fish S from which the dorsal fin and pelvic fin have been removed is cut into the drum cutter 101 of the third rotary blade device 1O110 located below the side surface of the frozen fish S.
．． Cut by 101, the blood and upper ribs of the frozen fish body S
Nerve punctures etc. are removed. The frozen fish body S, from which the opposing bones, upper ribs, nerve spines, etc. have been removed, is cut on the side by the first non-rotating blade 11.11.
The cutters 11b and llb remove the chips generated in the cutting process and adhere to the surface of the frozen fish S, thereby performing surface treatment on the frozen fish S. Here, surface treatment refers to smoothing the cut surface, and it may be possible to remove only the chips generated in the cutting process, or it may be possible to further cut the surface of the frozen fish body S to remove the chips generated in the cutting process. In addition to removing chips, the surface of the frozen fish body S may be finished; in short, at least:
It is sufficient to remove chips generated in the cutting process to form a smooth cut surface.
