In this state, the stopper member (not shown) between the auxiliary rotation shaft 59 and the roller 4 is removed, the roller 4 is removed from the auxiliary rotation shaft 59, and the roller is replaced with a desired roller. Note that the roller 4 may have any structure as long as it can be attached to and detached from the auxiliary rotation shaft 59 and can be securely fixed when attached.

In the open processing apparatus 1 for fish and shellfish according to the present invention having the above-described configuration, for example, when the shrimp A is opened from the center to two pieces, the driving means 6 is driven. The rotary blade 2 is rotated in the direction of the arrow in the figure, and the driving means 7 is driven to rotate the roller 4 at a lower speed than the rotary blade 2. At this time, the roller 37 and the chain 38 are simultaneously rotated in the direction of the arrow by the driving means 7.

After such a state, the belly side of the shrimp A is set to the roller 37 side, and the roller 37 and the chain 28
Insert shrimp A between The inserted shrimp A is conveyed to the rotary blade 2 side by the roller 37 and the chain 38. The shrimp A conveyed to the rotary blade 2 side (see FIGS. 5 and 6) is rotated by the rotary blade 2 at a higher speed than the roller 4 below. The back side is pushed into the concave groove 3a of FIG. In this state, the shrimp A
Is conveyed forward, and the center is vertically opened by the upper rotary blade 2. At this time, since the set interval is provided between the concave groove 3a and the blade 2a of the rotary blade 2, the shrimp A can be opened reliably and neatly without being cut into two pieces. Of course, when the fish is opened and processed in the same manner, the back opening or the belly opening processing can be easily performed without cutting the fish into two pieces. In the case of a shrimp or the like, by processing only the shell vertically from the abdomen (or from the back) using the apparatus of the present invention, the shell can be easily peeled when eating, and the food can be eaten without damaging the body. can do. Therefore, the food company can increase the commercial value by processing the shrimp and the like in this way.

The driving means for rotating the rotary blade 2, the roller 4, the roller 37 and the chain 28 may be driven by one series of driving means.

[0029]

As described above, in the apparatus for opening seafood according to the present invention, anyone can easily and accurately open two pieces of seafood in a short time, thereby improving the efficiency of opening processing and the product. Value can be improved.

Also, since the attitude holding groove is a V-shaped groove having a concave groove at the bottom, or a V-shaped or U-shaped groove, the difference between the rotational speed of the rotary blade and the rotation speed of the roller having the attitude holding groove is different. Together with this, the area on the opposite side of the seafood to be opened can be released into each groove, and the seafood can be held in a constant cutting posture, allowing accurate opening processing. it can. Therefore, there is no failure in the opening process and no waste of the seafood to be opened.
