Description

[Detailed description of the invention] The purpose of this invention is to apply appropriate moisture to the dried seaweed when drying the seaweed, prevent it from tearing when peeling the seaweed, and give the dried seaweed a glossy or glossy appearance. The invention relates to a seaweed drying device.

In order to achieve the above object, conventional seaweed drying equipment commonly uses a method in which a small boiler is connected to a burner and water vapor is mixed with the drying air and blown into the drying air.

However, with this method, it is very difficult to control the humidity of the drying air, and the drying conditions vary depending on the origin of the raw algae, the time of collection, etc., which subtly affects the quality of the dried seaweed.

Another cause is that moisture is not distributed at an appropriate rate inside the dryer, and furthermore, there are legal and economic constraints on the operation of the boiler.

Another method is known in which undried seaweed that has been subjected to papermaking and dewatering is put into a dryer in the reverse direction of the above method and taken out.

That is, in this method, undried seaweed is fed downward from the entrance of the dryer, transported in the longitudinal direction, and then circulated upward and taken out as dried seaweed from the same entrance.

According to this, the moisture generated from the undried seaweed can be applied to the dried seaweed located above, so the above-mentioned problems can be solved to a considerable extent.

However, the back half of the dryer is very important for drying the seaweed, and it is not preferable to apply too much moisture to it.

Nevertheless, this method has the disadvantage that there is a risk of excess moisture in the rear half of the dryer, and delicate control is required to balance this with the drying conditions of the first half.

The present invention aims to provide an extremely simple seaweed drying device in order to solve the above-mentioned problems and drawbacks all at once.

An embodiment of the present invention will be described below with reference to the drawings.

1 in the figure is the main body of the dryer, inside of which there is papermaking and
An endless chain 4 is installed in parallel with a large number of support arms 3 attached at regular intervals for intermittently transporting the dried seaweed cage 2.

Reference numeral 5 denotes a holder for the seaweed cage 2, which in this embodiment consists of a pair of rod-shaped members.

Reference numeral 6 denotes a parallel endless chain for intermittently transporting the seaweed cage 2 to perform papermaking, dewatering, peeling, etc. of the seaweed, and locking pieces 7 that engage with both ends of the holder 5 are attached at predetermined intervals. It is being

Also, a part of the endless chain 6 is connected to the entrance 1a of the dryer main body 1.
The nori cage 2 is brought close to the endless chain 4 through the endless chain 4, and at this location, the seaweed cage 2 together with its holder 5 can be transferred from each endless chain 6 to the endless chain 4, or vice versa. There is.

Then, the undried seaweed that has undergone papermaking and dewatering, that is, the undried seaweed a, is located at the top inside the dryer main body 1, and is passed around in the longitudinal direction by the endless chain 4, and the dried seaweed, that is, the dried seaweed is located below and is carried out of the aircraft from the same population 1a.

8 is a drying air inlet, through which dry hot air is blown.

Above this, an appropriate number of water bodies 9 according to the present invention are installed at predetermined intervals in the longitudinal direction.

The amount of water 9 is the steam generator 10-1.10 assembled in an appropriate number.
-2.10-3.10-4... It is appropriate to close them and arrange them in the longitudinal direction.

Both ends of the water volume 9 are connected to a pair of communication pipes 11, and a water supply pipe 12, a drain pipe 13, and an overflow pipe 14 are connected to these communication pipes 11, respectively.

The water volume 9 has a V-shaped or U-shaped cross section that is open at the top, and when drying air passes through the mutual gap between the mountings 9, the water in the water volume 9 is evaporated.

Further, the amount of water in the water amount 9 is controlled so that it decreases from the entrance 1a side of the dryer main body 1 toward the inner part.

In the case of this embodiment, water is supplied so that the amount of water decreases toward the rear from the steam generator 9-1 near the inlet 1a of the dryer main body 1.

Note that the communication pipe 11 may be provided outside the dryer main body 1.

Moreover, it is also possible to make all the communication pipes 11 common.

In addition, 15 and 16 in the figure are the cocks of the water supply pipe 12 and the drain pipe 13, respectively.

In the present invention, undried seaweed a is stored inside the dryer main body 1.
is located above, and the dried seaweed is located below, going around in the longitudinal direction.

Then, the amount of water is adjusted so that the amount of water decreases from the frontmost steam generator 10-1 near the inlet 1a side of the dryer main body 1 toward the rear, and the water inlet 8 provided on the lower side of the dryer main body 1 is adjusted. Blow in drier drying air.

Then, drying air is supplied to each steam generator 10-1.10.
-2.10-3.10-4 contacts the water volume 9, heats it and evaporates the water inside, and then passes through the mutual gap of the water volume 9 and rises.

The water volume 9 contains water such that the water volume decreases from the inlet 1a side of the dryer main body 1 towards the back, that is, the water volume of the steam generators 10-1 and 10-2 located in the front half. Steam generator 10-3.10- located in the rear inner half compared to
4 is small, or in some cases zero, so when the drying air comes into contact with the water amount 9, the drying air contains a lot of moisture in the first half of the dryer body 1, and the second half becomes drying air. The drying air has very low humidity.

The drying air containing moisture in an appropriate proportion can dry the undried seaweed a and provide an appropriate amount of moisture to the dried seaweed.

That is, in the inner rear half of the dryer main body 1, a very small amount of moisture, almost zero, is applied to the dried seaweed to make it shine, and in the front half of the dryer main body 1, the next process of drying the dried seaweed is applied. Sufficient moisture can be applied to the seaweed to prevent it from tearing when peeling the seaweed.

Moreover, since the undried seaweed a moves above the dried seaweed, the moisture generated therefrom does not affect the dried seaweed.

Therefore, according to the present invention, the dried seaweed has a luster or luster, does not break when peeling the seaweed, and can be obtained at a high quality and at a high price.

Moreover, by controlling the amount of water in the water installed in the longitudinal direction of the dryer body, the amount of evaporation of the water vapor generated from it is adjusted.
Since the humidity of the drying air is adjusted, the configuration and control are extremely simple, and the humidity of the drying air can be adjusted accurately.

Note that a boiler for adjusting the humidity of the drying air is not required.
