Description

The present invention relates to a plate-like nori production method and apparatus, and more particularly, to a plate-like nori transfer method and transfer device in a drilling step of a plate-like nori production method.

In the present invention, in particular, after washing raw laver, the laver is made into a plate shape to form a plate-like laver and heated by a drying means in the range of 30 ° C. to 90 ° C., with a moisture content of 1%. A rotary roller for drilling, which is formed by laminating a disk-shaped drilling tool equipped with a saw blade while transferring the dried plate-like laver to a range of 13% from Originally, in the process of perforating by two or more stages of multi-time operation, a transfer belt is provided above and below the plate-like nori and a transfer belt above and below the plate-like nori The present invention relates to an apparatus for producing a plate-like seaweed.

The plate-like seaweed is generally distributed in a dried product or in a roasted state, but it is brittle because of its low moisture content, and cracks and chips are likely to occur during the manufacturing process. On the other hand, “hardness” is one of the main factors that determine the quality of laver. However, the softer the lamellar laver, the stronger the palatability, so the texture is improved by making many holes in the laver. It is being considered.

The present inventors have paid attention to this hole and have been researching it.

In order to efficiently drill a large number of holes in a production line in a short time, a method such as continuously performing a drilling rotary roller on which a disk-shaped drilling tool equipped with a saw blade or the like is laminated can be used. Since the thickness of the laver is not constant and the surface is uneven, if unevenness or misalignment of the plate-like seaweed occurs during the transfer of laver, it will not be drilled at a predetermined position, By re-perforation, the strength of the plate-like laver is insufficient and the number of holes is insufficient, and the improvement of the texture of the plate-like laver is impaired, and the value as a product is remarkably lowered.

Usually, in the process of continuously punching plate-like nori using a rotary drilling roller in which disc-like drilling tools equipped with a saw blade or the like are laminated, the nori is transferred by a metal roller, In general, a resin roller or the like is brought into contact with one side of the plate-like seaweed and transferred.

When transporting a plate-shaped laver with a transfer belt or rollers made of various materials in contact with one side of the plate-shaped laver, unevenness of the plate-like laver speed or misalignment occurs, so a disc-shaped drilling tool equipped with a saw blade is stacked. It is difficult to adjust the drilling position in the drilling process using the drilling rotary roller.

In such a situation, the perforation accuracy to the plate-like seaweed is remarkably lowered, and the effect of improving the texture of the plate-like seaweed due to partial strength deficiency or insufficient number of holes cannot be fully exhibited.

Further, when the stacking of the disk-shaped drilling tools equipped with saw blades or the like is increased in order to increase the hole density, the gap between the tool and the tool is reduced, so that the drilling is close to the drilling position or re-drilling to the same drilling position. Will occur more, and the lack of partial strength and hole number of the plate-like seaweed will become remarkable.

On the other hand, when continuously drilling using two or more stages of rotating rollers for increasing the hole density, a transport belt, a roller made of various materials, etc. are brought into contact with one side of the plate-like laver and transferred. However, since it is more difficult to adjust the drilling position in the plate-like seaweed, re-drilling to the hole position occurs in the vicinity of the same hole or the same hole, resulting in partial strength deficiencies and holes in the plate-like nori. The shortage of the number becomes remarkable, and the texture improvement effect of the plate-like seaweed cannot be fully expressed.

In such a method, unevenness of the plate-like laver or misalignment occurs at the time of transfer, and the plate-like laver is not drilled at a predetermined position. Insufficient strength or insufficient number of holes occurs, and the texture of plate-like seaweed cannot be improved. In addition, in order to reduce the number of holes and improve the texture of the plate-like seaweed, it is effective to increase the area of each hole. Re-drilling to the same or the same drilling position cannot be avoided.

The present invention has been made as a result of intensive studies to solve the above problems.

The present invention, in the step of drilling plate-like nori, is transferred by a transfer belt provided above and below the nori, reducing the unevenness and misalignment of the plate-like nori, the proximity of the punching position to the plate-like nori The present invention provides a method for producing plate-like laver that prevents re-piercing and a plate-like laver production device that uses a transfer belt provided above and below the laver.

In the present invention, after the raw laver is washed, the laver is made into a plate shape to form a plate-like laver, which is heated in a range of 30 ° C. to 90 ° C. by a drying means, and has a moisture content of 1% to 13 %, A rotary roller for drilling, which is a stack of disk-shaped drilling tools equipped with saw blades, is placed perpendicular to the plate-like laver flow direction while transporting the dried plate-like seaweed to a range of 1%. In the step of perforating in two or more stages, a transfer belt is provided above and below the plate-like nori, and a transfer belt is provided above and below the nori It is related with the manufacturing apparatus of plate-like nori.

Further, when a plurality of rotary rollers for drilling, each having a disk-shaped drilling tool equipped with a saw blade or the like, are arranged at right angles to the direction, the transfer speed of the transfer belt of the rotary roller for drilling is set to the opposite direction. The present invention relates to a plate-like laver production method and a plate-like laver production device characterized in that the speed is reduced in a range of 10% to 45% below the transfer speed of the transfer belt.

According to the present invention, in the laver drilling process, uneven feeding and misalignment of the plate-like laver at the time of transfer can be reduced, and the proximity of the drilling position to the plate-like laver and re-drilling can be prevented. And the texture of a laver can be improved by making many holes in a plate-like laver effectively.
