Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting device for cut bonito flakes, and more particularly, to an apparatus for cutting cut bonito flakes such as flower bonito into small pieces.

[Conventional technology]

Conventional equipment for continuously processing cut bonito flakes such as flower bonito flakes into small pieces has been developed by installing an arc-shaped metal steel on the underside of the rotary serrated rotary blade along the rotary blade. The bonito flakes are supplied between the blade and the metal steel, and the rotary blade is rotated to crush the bonito flakes between the rotating blade and the metal steel, and the bonito flakes are crushed into small pieces by rubbing and rubbing. A structure is adopted in which the bonito flakes, which have reached a desired size, are taken out downward through the metal mesh.

[Problem that the invention seeks to solve]

In the above-mentioned conventional equipment, the bonito flakes are crushed or rubbed by the metal steel to turn them into powder, and then more powder is added to repeat the above process over and over again until the desired size is reached. generation, poor yield,
Moreover, it took a long time and the processing efficiency was poor.

Furthermore, as described in Japanese Unexamined Patent Application Publication No. 15463/1983, there is also known an apparatus for cutting cut pieces of dried bonito flakes using a roll cutter, but in this apparatus, cut pieces are cut as shown in FIG. 6a. In order to simply cut into fine pieces with a good texture, it is necessary to install a comb blade-like device on the exit side of the roll cutter, which can become clogged with fine pieces and become powder, reducing the yield. had low problems.

The present invention was made in view of these points,
The purpose is to cut cut bonito flakes into wavy pieces using a cutting device, reduce the generation of these pieces, and improve processing efficiency.

The present invention rotates the low-speed rotary disk and the high-speed rotary disk of the upper and lower cutting mechanisms at different circumferential speeds, and cuts bonito flakes such as bonito flakes from above both rotary disks of the upper cutting mechanism. When an object is thrown in, the cutting object that falls onto both rotary disks is moved to the entry area of both rotary disks by the rotation of the rotary disks, and is cut by the difference in circumferential speed between the low-speed rotary disk and the high-speed rotary disk. The object is hooked onto the cutting blade of the low-speed rotary disk and pulled by the cutting blade of the high-speed rotating disk, and the thin pieces cut into pieces by the upper cutting mechanism are pulled into wavy shapes. This thin piece of material is dropped above both rotary discs of the lower cutting mechanism, and similarly, the cut piece of material is cut again by the cutting blades of both rotary discs, and is cut into a predetermined shape. It is processed into small pieces of different sizes.
