[0054]

Since the present invention has the above structure, it has the following features.
It produces an effect like that.

First of all, the fish fed into the three-plate grater are cut off of the head of unnecessary portions (collectively those which are likely to cause inconvenience in cutting), take out the internal organs, cut off the tail, and dorsal fin. , pretreated the cut off of the buttocks Bille, then pre after processed fish is that cut open along the upper and lower cutters which are disposed on the same line, (also referred to Halas.) fish abdominal the Tyco type By applying pressure through the endless belt with the pressure roller, the mid-bone and the abdominal bone are excised from the fish body by the inclined cutter and at the same time divided into the left and right bodies (also called fillets), so that they are parallel to each other as in the past. With the two cutters that I arranged
Compared to the method of cutting the fish body into three pieces,
The number of people who are removed together with
Therefore, it is very useful in the processing of three pieces.

Further in accordance with the present invention, a series of three graters
When working, the abdomen can be removed together with the mid bone
Since it can be done, it is not necessary to separately remove the abdominal bone after the three-piece grazing process, and the work efficiency is further improved .

In short, since there is no abdomen, there is an effect that it is possible to immediately immediately proceed smoothly to each processing step such as the next step of smelting or slicing .

Further, by simply returning the operating rod to the original position with one touch, the pressure roller retracts via the lever and the pressure applied to the endless belt is reduced until it approaches zero, so that the abdomen touches the inclined cutter. Without, you can make fillets with abdominal bones.

When the abdomen is required for the abdomen, it can be operated with one touch, so one machine can serve as two machines, which is extremely economical.
