Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a cutting device for cut bonito flakes such as flower bonito flakes into small pieces. It is.

(Prior art) Conventionally, when cutting continuous dried bonito flakes into thin pieces, a rotary saw blade and a wire mesh provided in an arc shape along the rotary saw blade were used under the rotary saw blade. The bonito flakes are supplied between the rotating saw blade and the wire mesh, and the rotating saw blade is driven to crush the bonito flakes between the rotating saw blade and the wire mesh, and the bonito flakes are kneaded and rubbed. A device is used in which the pieces are made into small pieces by combining them, and the pieces of the desired size are taken out downward through the holes of a wire mesh.

(Problems to be Solved by the Invention) In the above-mentioned conventional device, the flower bonito powder is turned into powder during the process of being rubbed or rubbed by the wire mesh, and the fine pieces that do not have the desired size are repeatedly In order to repeat the process, more powder was generated, resulting in poor yield and time-consuming process, resulting in poor processing efficiency.

Furthermore, in the field of processing dried squid, as described in Japanese Utility Model Publication No. 51-16393 and Japanese Utility Model Application Publication No. 52-9681, a plurality of rotary disks with saw-like cutting edges formed on the outer periphery have been used. are arranged parallel to each other through a trough having a smaller diameter than the cutting edge of the cutting blade, and the cutting blades of one rotary disk and the cutting blade of the other rotary disk are arranged so as to alternately enter the trough of the other side, A processing device is known that rotates both rotary disks in opposite directions to tear the dried squid fed between the two rotary disks and loosen the dried squid meat fibers without separating them. . However, this processing equipment for squid rotates both rotating discs at the same circumferential speed or with a small difference in circumferential speed, and although it is suitable for processing thick dried squid,
When cutting a thin, soft material with a thickness on the order of microns into small pieces, it is not effective, and the problem arises that it sticks to the rotating cutting blade and cannot be separated.

The present invention has been made in view of the above points, and makes it possible to effectively cut cut bonito flakes such as flower bonito into small pieces, and
The object of the present invention is to provide a cutting device for cut bonito flakes that reduces the generation of powder during cutting and improves processing efficiency.

A plurality of low-speed rotary disks each having a cutting blade formed thereon are arranged in parallel through a valley portion having a diameter slightly smaller than the cutting edge of the cutting blade, and a saw-blade-shaped cutting blade is formed on the outer periphery of the high-speed rotating shaft. A plurality of high-speed rotary disks are arranged in parallel with each other through valleys having a diameter slightly smaller than the cutting edge of the cutting blade, and each of the cutting blades formed on the low-speed rotary disk is inclined in a direction opposite to the direction of rotation. At the same time, the cutting blades formed on each of the high-speed rotary disks are projected at an angle in the same direction as the rotating direction, and the cutting blades of the low-speed rotary disk and the cutting blades of the high-speed rotary disk are alternately connected to the other side. The rotational direction of the low-speed rotary disk and the high-speed rotary disk are arranged such that both cutting blades move from above to below in the part where the low-speed rotary disk and the high-speed rotary disk enter. The rotational direction of the low-speed rotary disk and the high-speed rotary disk are set to approximately 1:25 to 100, and the circumferential speed ratio of the low-speed rotary disk and the high-speed rotary disk is set to approximately 1:25 to 100.

(Function) The cutting device for cut bonito flakes of the present invention has a circumferential speed ratio of approximately 1:25 to 1:25 to 25.
When the cut pieces of dried bonito flakes are inserted from both rotary disks while rotating at 100 degrees, the cut pieces that have fallen onto both rotary disks are moved to the area where the cutting blades intersect with each other due to the rotation of the rotary disks. In this part, approximately 1

〔Effect of the invention〕

According to the present invention, the cutting blades of a plurality of low-speed rotary disks and the cutting blades of a plurality of high-speed rotary disks are arranged so as to alternately penetrate into the valleys of the other side, thereby forming a low-speed rotary disk. Each cutting blade is inclined and protrudes in a direction opposite to the rotational direction, and each cutting blade formed on each of the high-speed rotating disks is inclined and protruded in the same direction of rotation, and the low-speed rotating disk and the high-speed rotating disk are The rotational direction of the low-speed rotary disk and the rotational direction of the high-speed rotary disk are set in a direction in which both cutting blades move from upward to downward in the part where the cutting blades enter, and the circumferential speed ratio of the low-speed rotary disk and the high-speed rotary disk is set. Since the ratio is approximately 1 to 25 to 100, the cut pieces of bonito flakes are carried into the part where they enter by the rotation of both rotary discs. Due to the difference in circumferential speed, cut pieces of bonito flakes can be stopped by the cutting blades of the low-speed rotary disk and cut into pieces of desired size by the cutting blades of the high-speed rotary disk. It is possible to reduce the generation of powder because there is no kneading and rubbing with wire mesh as in the conventional method, and there is no disadvantage that the luster disappears due to rubbing and the value is lowered, and it has a good yield. It enables efficient production of high-quality pieces.
