Description

  The present invention relates to a dry seaweed manufacturing apparatus for manufacturing sheet-like dry seaweed from raw seaweed.

The dry seaweed production device for producing sheet-shaped dry seaweed includes a paper making unit that rolls up raw seaweed into a sheet shape on a cage held by a holder, and a dehydrating unit that dehydrates the raw seaweed that has been made up on the rice cake. The drying device is configured to dry the raw seaweed spread on the tub while the holder after the dehydrating section is fed and the holder is conveyed by an endless rotating chain as a conveying path. In recent years, the drying chamber has been increased in size for mass production, and in the increased drying chamber, an endless rotation chain for circulating and conveying the holder is provided in two upper and lower stages (for example, Patent Document 1).
JP 2003-144104 A

  In the case where the endless rotation chains are arranged in two stages in the drying chamber as shown in Patent Document 1, the upper space of the drying chamber (the upper half space where the upper endless rotation chain is disposed) and It is extremely difficult to manage the humidity in the lower space (the lower half space where the lower endless rotation chain is disposed) independently of each other.

  Specifically, for example, the holder that has passed through the dewatering unit is carried into the upper stepless rotation chain, and the upper space is circulated by the upper endless rotation chain, and then the upper endless rotation chain is moved to the lower endless rotation chain. When the holder is transferred to the moving chain by transfer means and the lower space is circulated by the lower endless rotating chain, the holder is then taken out of the drying chamber. It is generally preferable to lower the humidity of the lower space where the drying has progressed considerably and the water content has decreased, rather than the humidity of the space. However, in the conventional drying apparatus in which the upper endless rotation chain and the lower endless rotation chain are arranged in the same drying chamber (that is, in the same space), the humidity adjustment of the upper space and the lower space is performed independently of each other. For this reason, there is a problem that, for example, so-called cloudy dry nori is easily produced.

  Contrary to the above, after the holder passed through the dehydrating part is carried into the lower endless chain and circulated through the lower space, it is transferred to the upper endless rotation chain by the transfer means, and the upper space is circulated. There is also a method of carrying it out of the drying chamber later, but in such a method, raw nori with high moisture content circulates in the lower space, so the humidity in the lower space is high, and this humidity Since the air in the lower space (warm air) is blown up to the upper space, the humid air (warm air) is blown to the nori in the upper space where the drying has progressed considerably. There were problems such as being easy to be done.

  Therefore, the present invention eliminates interference between the upper space in which the upper stepless rotation chain is disposed and the lower space in which the lower endless rotation chain is disposed, and humidity adjustment of the upper space and the lower space is made independent of each other. It is an object of the present invention to provide a dry seaweed manufacturing apparatus equipped with a laver drying apparatus that can be performed independently.

  In the present invention, a paper-making part that rolls up raw nori on a sheet held by a holder, a dehydration part that dehydrates the raw nori drawn on the board, and a holder that has been dehydrated are fed And a drying device for drying raw nori spread on the corrugation while transporting the holder through the transport path, wherein the drying device includes an upper drying chamber and a lower step for discharging exhaust gas upward, respectively. Each of the drying chambers is provided with a transfer means for transferring the holder from the transfer path of the upper drying chamber to the transfer path of the lower drying chamber. In addition, a space is provided between the upper drying chamber and the lower drying chamber, and an exhaust passage that communicates with the interval and extends upward and discharges the exhaust gas blown up from the lower drying chamber to the outside is provided. And this exhaust passage It is partitioned to the upper space of the upper drying chamber by a partition wall.

  In the present invention, the upper drying chamber and the lower drying chamber are divided with an interval therebetween, so that humid air (warm air) in the upper drying chamber and the lower drying chamber does not interfere with each other, and the upper drying chamber does not interfere with each other. Thus, the humidity control of the drying chamber and the lower drying chamber can be performed independently and independently of each other, and therefore, drying of the fresh seaweed can proceed under an optimum humidity environment, and a high quality dry seaweed can be produced.
