DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for drying laver and a laver used for drying laver.

[0002]

2. Description of the Related Art Generally, laver is produced automatically by a fully automatic laver production apparatus.

[0003] That is, raw seaweeds of minced seaweed minced to a predetermined size are formed on a seaweed cage formed by knitting a large number of solid or hollow elongated straws made of synthetic resin. It is manufactured by dehydrating, then laminating the laver together with a laver in a drying room to which drying air is supplied, and drying the laver, and peeling the dried laver from the laver outside the drying room.

[0004]

From the end of October to the end of March of the following year, the harvesting period of the seaweed original algae differs in the adhesiveness to the seaweed cage depending on the growth state of the original seaweed collected during the period. For this reason, the use of laver cages that show the same adhesion of laver throughout the entire season is considered in terms of work efficiency and yield because dried laver is difficult to peel or breaks during the peeling process. There was room.

[0005] Therefore, conventionally, the laver of the laver is made of a resin material such as polypropylene.
According to the change in the adhesion of the laver, the adhesion of the higo was also changed appropriately.

[0006] However, when a seaweed cage made of knitted resin material is used, it takes a long time to dry the seaweed.

[0007] For this reason, various proposals have conventionally been made to improve the drying efficiency by increasing the speed at which laver is made or increasing the capacity to store the laver in the drying room in order to improve the production efficiency of laver. It has been done.

However, in order to increase the capacity of the drying room for laver, it is necessary to make the drying room large.
If the entire apparatus becomes large and the installation space is limited, it cannot be adopted.

The present invention has been made in view of these points, and can reduce the drying time of laver without any change in a fully automatic laver manufacturing apparatus, and can cope with a change in the adhesion of laver. Therefore, the dried seaweed can be dried so that it can be easily peeled off from the seaweed cage without being damaged, the temperature of the drying air can be reduced, and the drying efficiency can be improved and energy saving can be achieved. An object of the present invention is to provide a method for drying laver that can produce high quality laver and a laver cage used for drying laver.

[0010]

Means for Solving the Problems In order to achieve the above object, a method of drying laver of the present invention is to dry laver by passing laver made on laver in a drying chamber together with laver. In the drying method, a core material having good heat conductivity having a metal part having excellent heat conductivity as the laver is thinly coated by an adhesive force adjuster to a thickness that does not impair the heat conductivity of the core material. It is characterized in that a seaweed cage is used, which is made by knitting at least a part of the strawberries.

In the laver cage used for drying the laver of the present invention, a core material having good thermal conductivity and a metal part having excellent thermal conductivity is impaired by the adhesive force adjuster to impair the thermal conductivity of the core material. It is characterized in that it is formed by knitting at least a part of a string that is thinly coated to a thickness that is not so thick.

Further, the adhesive force adjuster is characterized in that a substance capable of emitting far infrared rays is mixed therein.

[0013]

According to the present invention, a metal part having excellent heat conductivity is provided.
A core material with good thermal conductivity is made into a seaweed plait knitted using at least a part of the ligament, which is thinly coated to a thickness that does not impair the thermal conductivity of the core material by the adhesive force adjuster. Because the dried seaweed is made to circulate in the drying chamber, the seaweed cage with good thermal conductivity is heated by the drying wind and the temperature rises. The amount of heat held by the laver will also be included,
The drying time can be greatly reduced as compared with the related art, and the temperature of the drying air can be reduced, so that high-quality laver is produced. Further, in order for the adhesive force adjuster to appropriately change the adhesive force of the lace according to the change in the adhesive force of the nori, the dried nori is dried so that it can be easily peeled off from the nori cage without breaking.

Further, by mixing a material capable of emitting far-infrared rays such as ceramics into the adhesive force adjuster, drying using far-infrared rays can be performed.

Next, a description will be given of a case where a method of drying laver performed using the laver cage 1 of each of the above embodiments is performed by a fully automatic laver manufacturing apparatus shown in FIG.

This fully automatic laver manufacturing apparatus is divided into a mechanical section 9 and a drying section 10. One mechanical section 9 is provided with an endless laver holder transporting means 12 for rotating the laver holder 11 in which the laver 1 shown in FIG. 1 is extended in a counterclockwise direction in FIG. The apparatus 13 is formed by sequentially disposing a device 13, a dehydrating device 14, a peeling device 15, and a cleaning device 16. The other drying unit 10 includes a drying room 17
An endless sea ladle holder conveying means 18 for rotating the laver holder 11 in a counterclockwise direction in FIG. 6 is provided therein. Both sea ladle holder transfer means 12,
A sea ladle holder transfer mechanism 19 for transferring the laver holder 11 is provided between the upper and lower portions 18.

In this fully automatic laver production apparatus, first,
The seaweed original algae is formed on each of the laver cages 1 spread on the laver holder 11 by the papermaking device 13. Next, the dehydration device 14 dehydrates the moisture from the original seaweed of seaweed using a dehydration means such as a sponge before drying. Subsequently, the dehydrated seaweed original algae are transferred together with the seaweed holder holder 11 by the seaweed holder holder transfer mechanism 19 from one seaweed holder holder transfer device 12 to the other seaweed holder holder transfer means 18, and then the drying chamber The circuit 17 is cycled for a predetermined time.

In the present embodiment, the seaweed made in the seaweed cage 1 in which the cladding 2 in which the core material 4 having good thermal conductivity is covered with the adhesive force adjuster 5 is knitted is circulated in the drying chamber 17 for drying. As a result, the drying efficiency is very high as follows.

In other words, the seaweed cage 1 in which the core 2 having good thermal conductivity is covered with the adhesive force adjuster 5 and knitted with the lace 2 is easily heated by a dry wind because of its good thermal conductivity, and the temperature is raised. I do. The laver paper-made in the laver cage 1 receives the heat of the drying wind from the front side, and is dried from the rear side by the heat of the laver 1 at a temperature suitable for drying. Therefore, the seaweed conventionally dried only by the heat energy held by the drying wind is further dried by the heat energy held by the seaweed cage 1 in the present embodiment.

The dried seaweed can be satisfactorily dried by the amount of heat supplied by the seaweed cage 1. According to the test of the inventor, the temperature of the conventional drying air can be reduced by about 10 to 20% (about 4 to 8 degrees). By reducing the temperature of the drying air, energy can be saved. By drying at a low temperature, the gloss of the dried seaweed is improved, the destruction of the nutrient components of the seaweed is suppressed, and the aroma of seaweed remains. Good nori is produced. Also, if a material capable of emitting far-infrared rays is mixed in the adhesive force adjusting body 5, the nori will also be dried by the far-infrared rays, so that the drying temperature can be further reduced and the quality can be further improved. Nori can be produced.

The dried seaweed is transferred from the drying chamber 17 to the mechanical unit 9 by the seaweed holder transfer mechanism 19, and then peeled off from the seaweed cage 1 by the peeling device 15. Furthermore, since the surface of the above-mentioned chicks is coated with an adhesive force adjuster 5 to the extent that thermal conductivity is not impaired in order to improve the removability of the nori, the nori In order to appropriately change the adhesive force of the laver 1 according to the adhesive force and the adhesive force, the dried laver can be dried so that it can be easily peeled off from the laver 1 without breaking. Accordingly, the efficiency of the peeling operation by the peeling device 15 is good, the breakage of the laver can be reduced, and the yield is good.

The seaweed cage 1 from which the seaweed has been peeled off is washed with a washing device 1
It is washed in 6 and again subjected to the next papermaking.

It should be noted that the present invention is not limited to the above-described embodiment, and can be modified as needed.
