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 paper sheets.

[Prior art and its problems]

In recent years, sheet nori has been produced mechanically.

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

For example, in a seaweed manufacturing apparatus that produces sheets of seaweed in a fully automatic manner, a papermaking apparatus, a dewatering apparatus, a drying apparatus, a peeling apparatus, and a washing apparatus are connected in circulation in the order of processing and processing the seaweed.

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 conveyed in circulation according to the conveyance line, and the seaweed is first made into paper sheets on this seaweed 1, then dehydrated, then dried for a predetermined period of time, and then dried. A sheet of seaweed is peeled off from seaweed N to produce a product. Afterwards, the seaweed cage is washed and used for the next papermaking process.

In addition, since the conveyance speed of the nori cage in the drying device is slower than the conveyance speed in other parts to ensure sufficient drying time, the nori basket is conveyed by separate conveyance devices in both parts, and the nori is transferred between the two parts. is passing high.

In addition, when it is necessary to form a long conveyance path in the drying device and there is a limit to the installation area of the drying device, it is possible to install multiple circuits in the drying chamber vertically and pass through each circuit in order to transport the seaweed into the cage. The process involves transporting and drying.

On the other hand, raw materials for seaweed to be dried include those with soft leaf bodies that retain a lot of water and are vulnerable to sudden drying, such as autumn new shoots and frozen first sprouts, and those with relatively hard leaf bodies that do not retain water. There are some that have less moisture and are more resistant to dryness.

Therefore, it is necessary to properly dry the seaweed by adjusting the transportation process of the seaweed in the drying chamber depending on the properties of the raw seaweed.

Furthermore, since the drying capacity of the drying atmosphere inside the drying chamber also changes depending on the outside air conditions, such as the temperature and humidity of the outside air, or the season, it is necessary to take responsibility for the transport process of the seaweed inside the drying chamber, as described above.

However, in a conventional device, for example, if a device is provided with a plurality of circulation circuits in the upper and lower stages, one of the circulation circuits in the uppermost and lowermost stages receives the seaweed from the transport path of the seaweed book outside the drying room, and then The seaweed cage is moved between the adjacent upper and lower circuits to the other circuit by a specially provided transfer mechanism, and finally the seaweed cage is transferred from the other circuit to the conveyance path outside the drying room. Therefore, once the seaweed bag is received by the circuit, it will not be transported outside the drying room until it passes through all the circuits, and the transportation process will be adjusted according to changes in the properties of the seaweed and the drying capacity to ensure proper drying. I couldn't do that.

Furthermore, the conventional apparatus had a complicated structure because it was necessary to provide a transport structure for the seaweed H between each adjacent circuit.

[Purpose of the invention]

The present invention has been made in view of these points, and when drying seaweed by providing a plurality of stages of circulation circuits above and below in a drying chamber, the number of stages of circuits for circulating seaweed can be changed as necessary. It is an object of the present invention to provide a method and device for drying seaweed that can perform proper drying and has a simple structure.

[Summary of the invention]

The method for drying seaweed, which is the first invention of the present invention, is to dry seaweed by transporting the seaweed, which has been made into paper sheets to a low quality, through a multiple-stage circulation path that circulates entirely or primarily within the drying chamber.

Each moss member holder 9 is conveyed (U) while supporting its support column 9b by a. On the other hand, the seaweed cage holder conveyance mechanism 16 of the machine body 7 is formed by a claw chain 24 provided with claws 25 and 25 for sandwiching the protruding portions 9a of the seaweed X holder 9 at regular intervals on an endless chain. 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.
A connecting rail 26 on which the protrusion 9a of the seaweed cage holder 9 is placed and guided is provided horizontally between the stop position of the seaweed cage holder 9 and the stop position of the seaweed cage holder 9. The end of the connecting rail 26 on the blade chain 20 side is connected to the holder guide 23, and the end on the pawl chain 24 side is connected to a holder guide 27 provided on the outer periphery of the pawl 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 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 movable 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.
It is formed by fixing an engaging piece 33 having a substantially U-shaped cross section that engages with the protruding portion 9a.

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 basin 8 spread on the seaweed basin holder 9 in the papermaking WJA device 10 and has been dehydrated in the dewatering apparatus 11 is transferred together with the seaweed protection holder 9 to the seaweed basin holder conveyance mechanism 16. The transfer mechanism 1 is connected to the seaweed holder conveyor M46 in the pre-drying chamber 4 by the claw chain 24.
7.

Next, in the delivery mechanism 17 part, the seaweed holder 9
is stopped by the pawl 24 in a vertical state 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 A holder 9 has a protrusion 9a that engages with the engagement g33.
The two blade members 19 of the blade ceno 20 are sliding on the connecting rail 26 while facing the connecting rail 26.
．． Move it to the base of the 19-space sky. This side sea convex cage holder 9 is moved through the intermediate state shown in FIG. It is delivered to the blade chino 20 side so as to be placed on the blade 19a. In this way, the seaweed summer holder 9
is carried into the preliminary drying chamber 4.

Next, while the claw end 24 remains stationary, only the blade end 20 is turned downward (in the opposite direction in FIG. 4) by one bit. As a result, the seaweed holder 9 newly delivered to the vane die 20 as described above is carried toward the back of the pre-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 tray 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, support part 0
Compressed air is supplied to the right side of the permanent magnet 31 of No. 30, and the permanent magnet 31, moving body 32J3, and engagement piece 33 are moved to the left, and the nori tray holder 9 is transported into the preliminary drying chamber 4. The protruding portion 9a passes through the opposite path to the claw buen 24.
is moved until it enters the empty claw 25 of. In this way, the nori container holder 9 is carried out to the nori container holder transport mechanism 16.

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

In the pre-drying chamber 4, the seaweed circulates together with the seaweed A holder 9 as the seaweed cage holder transport mechanism 6 advances, passes through the upper drying chamber 2 and the punching metal 5, and enters the pre-drying chamber 4. Preliminary drying is performed by heated air 14 sent from above. Since the heated air 14 sent into the pre-drying chamber 4 is in a breeze state and at a relatively low temperature, the interior of the pre-drying chamber 4 is in an atmosphere with low drying ability, and the seaweed containing a large amount of free water is is pre-dried very well and is ready for the next main drying in the drying chamber 2.

Further, if necessary, the seaweed melon holder conveyance mechanism 6 is rotated in the π1 direction to perform preliminary drying.

After this preliminary drying, the seaweed 21 holder 9 is transported by the seaweed summer holder transport mechanism 16 and stopped at the connecting rail 26 portion of the delivery mechanism 17 connected to the seaweed cage holder transport mechanism 3 of the drying chamber 2. Then, the seaweed cage boulder 9 is transferred to the vane chino 20 of the seaweed A holder transport mechanism 3 in the same manner as in the above case.

After that, if the actual dried pan seaweed has a high water retention capacity, the blade 20 is rotated so as to move the seaweed prize holder 9 downward (around the opposite part 81 in Fig. 4). If there is a small amount of damage, avoid rotating in the opposite direction.

To explain further, seaweed with a lot of water retention is in the front unit 2.
In part a, the drying chamber 2 is passed through the lower side far from the heated air 14.
Since the air is carried inside, the drying capacity 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 a low water retention capacity is carried into the drying chamber 2 through the upper part of the first part 1 to 28 near the heated air 14, so the initial main drying is carried out in an atmosphere with an appropriate relatively high drying capacity. Similar to the above, it dries well without clouding, shrinking, or raw areas.

Then, as the blade cenograph 20 advances, the seaweed conveyed from either the upper or lower height position moves toward the back of the drying chamber 2, where its direction is reversed up to 180 degrees m around the horizontal axis. , then head forward.

In the support delivery mechanism 17 portion, the claw die 2 of the nori member holder conveyance mechanism 16 on the machine main body 7 side is operated in the same manner as described above.
4. In this way, while the seaweed circulates around the drying chamber 2, it is dried extremely well in an atmosphere with a drying capacity 5 times higher than that during pre-drying, and then transported to the next peeling device 12.

In this way, in this embodiment, the nori cage holder transport mechanism 16 on the machine main body 7 side outside the drying chamber 2 is effectively used to transport the nori cage holders in the upper and lower two stages 3 and 6 in the drying chamber 2. The commercial moss melon boulder 9 can be transferred between
The structure is simple because it does not require any special transport means as in the prior art.

This is particularly effective when the drying chamber 2 is provided with three or more upper and lower stages of seaweed cage holder conveyance machines.

In addition, in this embodiment, if the nature of the seaweed does not require pre-drying, the transfer mechanism 17 between the frozen seaweed holder transport mechanisms 6 and 16 inside and outside the pre-drying chamber 4 can be stopped to dehydrate the seaweed. The dried seaweed can be subjected to main drying without pre-drying, and drying can be carried out according to the nine qualities of seaweed. This means that the nori bamboo holder conveyance mechanism in the drying chamber, regardless of whether it is for main drying or pre-drying,
It is very effective when formed in three or more upper and lower stages.

That is, by operating or stopping the delivery mechanisms 17 and 17 of m number, respectively, it is possible to freely adjust the conveyance process of the seaweed in the drying chamber 43 and perform optimal drying. Thereby, it is possible to omit adjusting the conveyance speed of the seaweed basket holder conveyance mechanism and the temperature of the heated air 14.

In addition, in this embodiment, heating inside the drying chamber 2) 414
Since the feeding direction of the middle and innermost units 2a is changed to be opposite to that of the frontmost units 1 to 2a, the drying ability of the atmosphere can be appropriately changed while the seaweed circulates inside the drying chamber 2. It is possible to carry out better drying.

Moreover, the top and bottom of the seaweed that circulates in the drying chamber 2 by the blade cenograph 20 are reversed before and after the reversal at the inner part, and uneven drying of the top and bottom of the seaweed is also eliminated.

In addition, although the nori T-holder 9 is transferred between the nori t-holder 9 and the nori holder transport mechanisms 3 and 6 and 16 at one location, the circulating direction of the nori holder 9 can be freely switched between forward and reverse directions. The paper making device 10 and dewatering device 11 that handle treated water can be installed below the stripping device 12, and the structure of the machine body 7 can be simplified.

Alternatively, 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 sho holder transport mechanism 16 may be transported in the opposite direction.

In addition, in the present invention, as described above, the number of stages of the seaweed cage holder transport mechanism installed in the drying chamber may be three or more stages, and it does not matter whether the drying is pre-drying or main drying. Moreover, 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. The seaweed H boulder conveying mechanisms 3 and 6 in the stalk, drying chamber 2 and pre-drying chamber 4 may be formed so as to be able to rotate only in the -h direction.

Note that as the transfer mechanism, it is possible to use ordinary reciprocating means such as a combination of cylinders, etc., a reciprocating slider, a chino drive, and the like.

〔Effect of the invention〕

In this way, the seaweed drying method and apparatus of the present invention can be used to dry seaweed by providing a plurality of circuits in the drying chamber vertically. It has advantages such as being able to perform drying and also having a simple structure.
