Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laver drying method and a laver drying apparatus for drying laver in a fully automatic laver manufacturing apparatus.

[0002]

2. Description of the Related Art In recent years, plate laver has been mechanically mass-produced by a fully automatic laver manufacturing apparatus.

As shown in FIG. 5, in a fully automatic laver manufacturing apparatus for automatically producing plate laver, as shown in FIG. 5, a laver machine 1, a dehydrator 2, a laver dryer 3, and a laver The peeling machine 4 and the laver washer washing machine 5 are connected in circulation. The production of plate laver by this fully automatic laver production apparatus is performed as follows. That is, in the present apparatus, a large number of laver cages are circulated and transported by the transport mechanism,
First, laver is made on the laver, dehydrated, dried for a predetermined time, and then the dried laver is peeled off from the laver to obtain a product. After that, the laver is washed and used for the next papermaking.

[0004] In a fully automatic laver manufacturing apparatus, a machine base body A and a laver drying apparatus B are divided.

On the other hand, in the machine base body A, a laver making machine 1, a dehydrator 2, a laver peeler 4 and a laver washing machine 5 pass between a laver holder transport mechanism 6 for a machine chain in the form of a nail chain.
It is formed so that the laver is transported intermittently in the vertical plane.

In the other laver drying apparatus B, one of the upward and downward drying winds W is fed into the drying chamber 7, and the laver is transported by a blade chain-shaped laver holder transport mechanism 8 for the drying chamber. With the laver holder 9 on which the dried and dried laver is mounted, it is transported from the front to the rear of the drying chamber 7 in a state of standing vertically, and the transport direction is reversed by 180 degrees around the horizontal axis. Further, the seaweed is dried while being intermittently circulated in the drying chamber 7 so as to be conveyed toward the front of the drying chamber 7.

[0007]

However, since the laver holder 9 is transported vertically in the drying chamber 7 by the laver holder transport mechanism 8 for the drying chamber, it is supported by the laver holder 9. For example, the downstream side of the dried seaweed itself is harder to dry than the upstream side with respect to the upward drying wind W, and the drying chamber is further transported toward the back of the drying chamber 7 and forward. Since the drying air W easily stays in the central portion (the portion indicated by the dashed line C in FIG. 5) of the transport path of the laver holder 9 supported by the laver holder transport mechanism 8, the central portion is dried from the upper and lower ends. However, there is an inconvenience that drying unevenness occurs even with one sheet of laver. In particular, today, in order to produce a large amount of plate nori, nori cage holder 9
As shown in FIG. 6, the laver 9a can be mounted in two or more stages in the vertical direction to improve the production efficiency.
There is a disadvantage that the drying unevenness of the laver occurs not only on the single laver itself but also due to a difference in the paper making position on the laver holder.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object of the present invention is to provide a seaweed drying apparatus which can reliably dry seaweed without causing unevenness in drying to obtain high-quality seaweed and has a simple structure. It is an object of the present invention to provide a laver drying method and a laver drying apparatus that can be obtained.

[0009]

According to a first aspect of the present invention, there is provided a laver drying method according to the present invention, wherein a laver is mounted on a laver cage holder by a laver cage transport mechanism for a drying room. In the nori drying method of drying the nori by feeding the drying air into the drying chamber while circulating and transporting the dried nori in the vertical plane, the direction of the blowing of the drying air into the drying chamber is upward and downward, or downward and upward. The laver is dried by alternately switching the drying chamber from the front to the back in order.

In order to achieve the above object, a laver drying apparatus according to the present invention according to claim 2 is provided in a drying chamber in which a laver cage transport mechanism for a drying chamber capable of circulating and transporting a laver cage holder in a vertical plane is installed. In a laver drying device that supplies drying air to dry laver, an upward blowing mechanism that directs the direction of the drying air into the drying chamber upward and a downward blowing mechanism that directs the drying air downward from the front to the back of the drying chamber. It is characterized in that they are formed in order.

In the present invention, the laver drying apparatus is operated by the laver drying method, so that the laver supported by the laver cage holder being circulated and transported by the laver holder transport mechanism for the drying chamber in the drying chamber. It is possible to dry the laver by sequentially switching the upward drying air and the downward drying air in the front-rear direction of the drying chamber. As a result, the seaweed circulated and conveyed in the drying chamber is dried by sequentially reversing the direction of the drying air, and is uniformly dried without drying unevenness, thereby producing high-quality seaweed.
