Description of the Related Art A dry laver manufacturing apparatus for producing a sheet of dry laver is made by laminating raw laver on a cage held in a holder, and dehydrating the raw laver thus formed with a dehydrating sponge. Then, the holder is fed into the drying chamber, the raw nori is dried while being transported in the drying chamber, and then the dried nori is dried and peeled off from the pond. A conventional drying chamber has a heating section on one side thereof. The outside air is sucked into the heating section, heated by a heating means, and hot air generated by heating is dried in the drying chamber. The raw seaweed was sent to the inside and spread on the cage that was transported in the drying room. [0004] A plurality of cages are held in the holder, but in recent years, the number of cages held by the holder has increased in response to a demand for mass production. When the number of cages increases in this way, the lateral dimensions of the holder also increase and become longer, and accordingly, the lateral dimensions of the drying chamber also increase. On the other hand, in the conventional drying chamber, a heating section is provided only on one side (one side) as described above, and hot air is supplied only from this side (one side) to dry the raw seaweed. I was trying to make it. However, in the conventional apparatus in which the hot air is sent only from one side of the drying chamber, the hot air is uniformly blown on the raw seaweed spread on a large number of pens held in the long holder as described above. This is difficult, and there is a problem that drying unevenness is likely to occur in the lateral direction of the holder. Accordingly, the present invention provides an apparatus for producing dried laver which can prevent the occurrence of uneven drying by uniformly blowing hot air onto the raw laver spread on a large number of cages held in a long holder. The purpose is to: [0007] The apparatus for producing dry laver of the present invention comprises a paper laminating unit for laminating raw laver on a cage held by a holder, and a dewatering unit for dehydrating the raw laver laden. In a dry laver manufacturing apparatus comprising a pre-treatment section including a pre-treatment section and a drying chamber disposed at the rear of the pre-treatment section and drying the raw nori spread on the cage while transporting the holder, heating is performed on both sides of the drying chamber. Unit, and a fan draws outside air into the heating unit, heats the heating unit with heating means disposed inside the heating unit, and generates hot air generated by heating from both sides of the drying chamber. To the lower part of the drying chamber to raise the inside of the drying chamber.
In addition to providing a partition wall that divides the room into left and right,
A current plate is provided at the lower part of the drying chamber, and the hot air is blown through the current plate.
To raise the inside of the drying chamber . [0008] In the above configuration, since the heating section is provided on both sides of the drying chamber, the warm air generated by the heating section is
It is sent into the drying chamber from both sides of the drying chamber. Therefore, the fresh seaweed can be dried while uniformly suppressing the drying unevenness by blowing the hot air uniformly on the seaweed spread on the cage having a large number of holders. In this case, a partition wall is provided at the center of the drying chamber, and a rectifying plate is provided at the bottom of the drying chamber, so that warm air can be blown up more evenly and raw seaweed can be dried evenly. .
