Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seaweed drying method and apparatus for drying seaweed made into sheets on a seaweed cage.

[Prior art and its problems]

In recent years, plate nori has been mass-produced mechanically.

There are two types of machines for making this plate nori: fully automatic and semi-automatic.

For example, in a seaweed manufacturing device that manufactures sheet nori in a fully automatic manner, in the order of the seaweed processing steps, the sheet-making device,
A dewatering device, drying device, stripping device, and cleaning device are connected in circulation.

The production of plate nori using this nori production apparatus is carried out as follows. That is, in this device, a large number of seaweed cages are circulated and conveyed by the transport mechanism, and the seaweed is first made into sheets on the seaweed cages, then dehydrated, then dried for a predetermined period of time, and then dried. The dried sheets of seaweed are peeled off from the seaweed cage and made into products. Afterwards, the seaweed cage is washed and used for the next papermaking process.

In addition, the conveyance speed of the seaweed cage in the drying equipment is
In order to ensure sufficient drying time, the transport speed is slower than that in other parts, so the seaweed cages are transported by separate transport devices in both parts, and the seaweed cages are delivered between them.

In order to maintain high quality of the plate nori produced by the nori production apparatus constructed in this way, it is necessary to dry it well after dehydration. That is, it is necessary to dry the sheet nori in an appropriate drying atmosphere so that it does not become cloudy, shrink, or have any green spots.

Generally, seaweed that has undergone a dehydration process has a large amount of free water between its leaves. When seaweed containing a large amount of free water is subjected to main drying in an atmosphere with high drying capacity, the free water is rapidly evaporated, causing the seaweed to shrink and become cloudy.

However, since the conventional seaweed drying method does not dry the seaweed after dehydration in an optimal drying atmosphere, there is a risk that the seaweed may shrink, become cloudy, or have green parts. Also, this shrinking, cloudy,
In order to prevent the occurrence of green spots, etc., it is sufficient to lower the drying capacity of the heated air sent into the drying chamber, but this has the disadvantage that it takes a long time to complete the main drying.

Furthermore, in the conventional seaweed drying method, heated air is sent into a long drying chamber from front to back, and the dehydrated seaweed is transported into the drying chamber together with the seaweed cage from the front opening of the drying chamber at either the top or bottom of the drying chamber. transport it more,
Next, the conveyance direction is reversed vertically inside the drying chamber and the conveyance direction is reversed and the conveyance is circulated, drying is carried out during this period.Finally, the conveyance direction is reversed vertically from the front opening to the inside, and the conveyance is directed toward the peeling device from the opposite height position. It is being carried out.

However, in the conventional seaweed drying method, while the heated air is sent in a fixed direction into the drying chamber, the direction in which the seaweed circulates within the drying chamber is also constant, and the drying atmosphere changes depending on the properties of the seaweed. It was not possible to dry the sheet nori by changing the drying conditions, and there was a possibility that the commercial value of the plate nori would be lost.

This is because some types of seaweed have soft leaves, such as autumn new shoots and frozen first buds, which have soft leaves that hold a lot of water and are vulnerable to sudden drying, while others have relatively hard leaves that hold less water and are susceptible to drying out. There are strong ones. Despite the various properties of raw seaweed, conventionally all seaweed is dried while being transported on a fixed circuit, which results in uneven drying, resulting in cloudiness, shrinkage, and raw parts. There was a risk that this would occur.

[Purpose of the invention]

The present invention has been made in view of these points, and it is possible to dry seaweed with a large amount of free water in a low air volume and/or low temperature atmosphere with low drying ability, and furthermore, it is possible to dry seaweed that has a large amount of free water. By changing the circulation circuit in the drying room according to the properties of the seaweed, it is possible to dry any type of seaweed well without causing cloudiness, shrinkage, or raw parts, and it is possible to produce sheet seaweed with a high commercial value. An object of the present invention is to provide a method and device for drying seaweed.

[Summary of the invention]

The seaweed drying method, which is the first invention of the present invention, pre-dries seaweed prepared on a seaweed cage in a period when it contains a large amount of free water in an atmosphere with low airflow and/or low temperature and low drying ability, and then The main drying is performed in an atmosphere having a higher drying capacity than that during the preliminary drying.

The seaweed drying device, which is the second invention of the present invention, has a pre-drying chamber for pre-drying seaweed prepared on a seaweed cage in an atmosphere with low air volume and/or low temperature and low drying ability during a period when the seaweed is made into paper sheets on a seaweed cage and contains a large amount of free water. The present invention is characterized in that a drying chamber is provided in which the pre-dried seaweed is main-dried in an atmosphere having a higher drying capacity than that during the pre-drying.

It is formed by a pawl chain 24 provided with 5 and 25. The transfer mechanism 17 transfers the nori cage holder 9 between each blade chain 20 of the nori cage holder transport mechanisms 3 and 6 and the claw chain 24 of the nori cage holder transport mechanism 16. As shown in FIG. 4, this delivery mechanism 17 places the protrusion 9a of the nori cage holder 9 between the stop position of the blade member 19 of the blade chain 20 and the stop position of the claw 25 of the claw chain 24.

As shown in FIGS. 7 and 8, a transfer mechanism 29 is provided on the outside of the connecting rail 26 to move the seaweed cage holder 9 between the blade chain 20 and the claw chain 24. This transfer mechanism 29 has a support member 30 made of a long pipe fixed in parallel with the connecting rail 26, and a permanent magnet 31 is provided in the support member 30 so as to be able to slide back and forth by air pressure or the like. A moving body 32 is provided on the outside of the permanent magnet 31 so that it can be attracted by the magnetic force of the permanent magnet 31 and can freely slide back and forth following the reciprocating motion of the permanent magnet 31.
An engaging piece 33 having a substantially U-shaped cross section that engages with the protruding portion 9a of the seaweed cage holder 9 is fixedly attached thereto.

Next, the operation of this embodiment will be explained based on the method of the present invention.

First, heated air 14 is supplied into the drying chamber 2. Next, the seaweed that has been made into paper sheets on the seaweed cage 8 spread on the seaweed cage holder 9 in the papermaking device 10 and has been dehydrated in the dewatering device 11 is transferred together with the seaweed cage holder 9 to the seaweed cage holder conveyance mechanism 16. It is transported by the claw chain 24 toward the transfer mechanism 17 with the nori cage holder transport mechanism 6 in the pre-drying chamber 4 .

Next, preliminary drying is performed.

First, in the delivery mechanism 17, the nori cage holder 9 is stopped in a vertical state by the claw chain 24 with its protrusion 9a at the same height as the connecting rail 26, as shown in FIG. At this time, the protrusion 9a of the seaweed cage holder 9 is engaged in the recess of the engagement piece 33 of the transfer mechanism 29, as shown by the chain lines in FIGS. 7 and 8. Subsequently, compressed air is supplied to the left side of the permanent magnet 31 of the support member 30, and the movable body 32 and the engagement piece 33 are moved along the support member 30 together with the permanent magnet 31, as shown in FIGS. 7 and 8. , move it to the right. As the engaging piece 33 moves to the right, the seaweed cage holder 9
The protruding portion 9a engaged with the blade chain 20 is slid on the connecting rail 26 and moved to the empty root portion between the two blade members 19, 19 of the blade chain 20 which is open and facing the connecting rail 26. At this time, the seaweed cage holder 9 is guided by the guide 34 at its lower end and is moved through the intermediate state shown by the chain line in the same figure, and finally the support portion 9b is attached to the blade member 19 of the blade chain 20. It is delivered to the vane chain 20 side so as to be placed on the pin 19a. In this way, the seaweed cage holder 9 is transported into the preliminary drying chamber 4.

Next, only the blade chain 20 is rotated downward (counterclockwise in FIG. 4) by one pitch while the pawl chain 24 remains stopped. As a result, the seaweed cage holder 9 newly transferred to the feather chain 20 as described above.
is transported toward the back of the preliminary drying chamber 4. At the same time, the nori that has been pre-dried by circulating around the pre-drying chamber 4 supported by the upper adjacent blade member 19 is returned to the same height as the connecting rail 26 of the delivery mechanism 17 together with the nori holder 9. Stop. At this time, the protrusion 9a of the seaweed cage holder 9 enters the recess of the engagement piece 33 of the transfer mechanism 29 and engages with the engagement piece 33. Next, compressed air is supplied to the right side of the permanent magnet 31 of the support member 30, and the permanent magnet 31 and the moving body 32 are
Then, the engaging piece 33 is moved to the left, and the seaweed cage holder 9 passes through the opposite path to the one used when conveying into the pre-drying chamber 4, so that its protrusion 9a enters the empty claw 25 of the claw chain 24. You will be moved until you enter. In this way, the seaweed cage holder conveyance mechanism 1 of the seaweed cage holder 9
6 is carried out.

Thereafter, the claw chain 24 is advanced by one pitch, and the next new seaweed cage holder 9 is transported into the preliminary drying chamber 4.

Then, in the pre-drying chamber 4, the seaweed circulates together with the nori basket holder 9 as the laver cage holder transport mechanism 6 advances, and passes through the upper drying chamber 2 and the punching metal 5 into the pre-drying chamber 4. It is preheated by heated air 14 sent from above. Heated air 14 sent into this preliminary drying chamber 4
Since there is a light breeze and a relatively low temperature, the inside of the pre-drying chamber 4 is in an atmosphere with low drying capacity, and the seaweed containing a large amount of free water is pre-dried very well, and the seaweed is dried in the next drying chamber 2. Prepare for main drying. Further, if necessary, the seaweed cage holder conveyance mechanism 6 is rotated clockwise to perform preliminary drying.

Next, main drying is performed.

After this pre-drying, the seaweed cage holder 9 is transported by the seaweed cage holder transport mechanism 16 and stopped at the connection rail 26 of the delivery mechanism 17 connected to the seaweed cage holder transport mechanism 3 in the drying chamber 2. It will be done. Then, the seaweed cage holder 9 is transferred to the blade chain 20 of the seaweed cage holder transport mechanism 3 in the same manner as in the above case.

After that, if the seaweed to be dried has a high water retention capacity, the blade chain 20 is rotated so as to move the seaweed cage holder 9 downward (counterclockwise in Figure 4). If so, rotate it in the opposite direction.

To explain further, seaweed that has a high water content is transported into the drying chamber 2 through the lower side far from the heated air 14 in the front unit 2a, so the drying ability of the atmosphere is lower than when it passes through the upper side.
Therefore, since the seaweed is dried in an atmosphere with an appropriate low drying capacity during the initial stage of main drying, the seaweed can be dried well without cloudiness, shrinkage, green parts, etc., as in the conventional method.

In addition, seaweed with low water retention is transported into the drying chamber 2 through the upper part near the heated air 14 in the front unit 2a, so the initial main drying is carried out in an atmosphere with an appropriate relatively high drying capacity. As mentioned above, the drying process is excellent without clouding, shrinkage, or raw areas.

Then, as the blade chain 20 advances, the seaweed transported from either the upper or lower height position is transported to the drying chamber 2.
It heads towards the back of the room, where the conveyance direction is reversed 180 degrees around the horizontal axis, and then it heads towards the front.
Thereafter, in the delivery mechanism 17 section, the seaweed cage holder conveyance mechanism 16 on the machine main body 7 side is operated in the same manner as described above.
is conveyed to the claw chain 24. In this way, while the seaweed circulates within the drying chamber 2, it is dried extremely well in an atmosphere with a higher drying capacity than during pre-drying, and then transported to the next peeling device 12.

In addition, in this embodiment, the feeding direction of the heated air 14 into the drying chamber 2 is set to the intermediate and innermost units 2.
Since the direction in a is changed to be opposite to that of the front unit 2a, the drying ability of the atmosphere can be appropriately changed while the seaweed circulates in the drying chamber 2, resulting in better drying. can be done.

Further, the seaweed circulating in the drying chamber 2 by the blade chain 20 is turned upside down before and after it is turned over at the inner part, and uneven drying of the seaweed in the top and bottom is also eliminated.

In addition, the seaweed cage holder conveyance mechanisms 3, 6, and 16
Although there is only one delivery position for each of the seaweed cage holders 9, the circulation direction of the seaweed cage holders 9 can be freely switched between the forward and reverse directions. The device 11 can be installed below the peeling device 12, and the structure of the machine body 7 can be simplified. Also,
Conversely, the paper making device 10 and the dewatering device 11 may be provided above, the peeling device 12 may be provided below, and the nori cage holder transport mechanism 16 may be transported in the opposite direction.

In the present invention, the feeding direction of the heated air 14 into the drying chamber 2 may be limited to either upward or downward without being changed during the circulation of the seaweed. Moreover, the seaweed cage holder conveyance mechanism 6 in the pre-drying chamber 4 may be formed so as to be able to rotate only in one direction.

FIG. 9 shows another embodiment of the device according to the invention.

In this embodiment, the nori cage holder 9 is moved in a substantially vertical direction between the nori cage holder transport mechanisms 3 and 6 in the drying chamber 2 and the nori cage holder transport mechanism 16 in the main body 7 of the machine. It is designed to be passed on to each other. That is, the stop position of the blade member 19 facing downward of the blade chain 20 of the seaweed cage holder transport mechanism 3 and the stop position of the blade member 19 of the seaweed cage holder transport mechanism 1
The two holder guides 23 and 27 are connected by a connecting rail 26 between the pawl chain 24 of No. 6 and the stopping position of the pawl 25 facing upward, and the nori cage holder 9 is connected between them.
It is formed by providing a transfer mechanism that engages with the protrusion 9a and moves it up and down.

This embodiment is preferably used when the seaweed cage holder 9 cannot be transferred horizontally between the seaweed cage holder transport mechanisms 3 and 16.

10 and 11 show other embodiments of the vane chain. The blade chain 35 of this embodiment has long L-shaped blade members 36 protruding from only the inner links 18 of the endless chain, and the protruding portion of the nori cage holder 9 is inserted between these blade members 36, 36. 9a, and the protruding part 9a is supported by an endless chain and the holder guide 23 provided on the outside thereof to prevent it from falling off.Furthermore, the tip part of the blade member 36 supports the support part 9b of the nori cage holder 9. The seaweed cage holder 9 is transported while being supported.

As the transfer mechanism, ordinary reciprocating means such as a combination of cylinders, a reciprocating slider, a chain drive, a cam drive, etc. can be used.
