ましい状態とは言えない。The weight per piece of dry seaweed (21 cm × 19 cm) is specified to be around 3 g in the standard of the Saga Ariake Sea Fisheries Cooperative Association, for example, less than 2.7 g is non-standard, and 3.5 g or more is Heavy standards are not met. In other words, if it does not fall within this range, the product will be defective, and if the weight is insufficient, the product value will be lost. Conventionally, this weight adjustment has been performed by an expert by adjusting the concentration of the seaweed mixed solution based on experience. Currently, dry seaweed is generally produced in large quantities using a large-sized seaweed dryer. This seaweed dryer requires about 2 hours from the loading of raw seaweed to the completion of drying. In other words, even if the dry laver delivered from the laver dryer is found to be defective due to its insufficient weight, there are already thousands of dried laver inside the laver dryer, which have been made with almost the same concentration. All will be defective. For this reason,
The producer side tends to increase the concentration of the seaweed mixed solution and set the weight to a heavier weight within the above range, but this means that the number of produced sheets will decrease, which is a favorable state for the producer side. I can't say.
本発明の目的は、ある濃度で抄かれた海苔の乾燥重量が

ようにすることである。The purpose of the present invention is to enable the dry weight of the seaweed extracted at a certain concentration to be known in a short time, so that the proper concentration of the seaweed mixed solution corresponding to any dry weight of the seaweed can be set early, and the dry seaweed is dried. Is to ensure that the weight of the product is within the specified range and to eliminate the occurrence of defective products. And by eliminating the waste of thickening the concentration of the seaweed mixture more than necessary to escape from the lack of weight as in the past, it is possible to obtain as many dry seaweed as possible within an appropriate weight range. is there.

FIG. 1 shows an internal structure of an embodiment of the present invention, a schematic cross-sectional view, FIG. 2 is a schematic plan view of the drying chamber taken along the line AA in FIG. 1, and FIG. 3 is a B of FIG. -B sectional drawing, FIG. 4 is CC sectional drawing of FIG. Reference numeral 1 is a seaweed quick-drying device, which includes a drying box 2 and a blower 3. The upper part of the drying box 2 is open, and the opening 20 has an insulating lid 21.
Is attached so that its base end can be rotated by a hinge 22. In addition, the width of the heat insulating lid 21 is set to be slightly shorter than the width of the drying box 2, and the exhaust port 23 is formed in the upper part of the drying box 2 even when the heat insulating lid 21 is closed. Below the heat insulating lid 21, a wind guide lid 24 is also attached so that its original side can be rotated by a hinge 25. The wind guide lid 24 is configured to incline slightly downward toward the tip side when closed. The tip end side of the air guide lid 24 is also formed slightly shorter than the heat insulating lid 21, and a gap is provided between the air guide lid 24 and a side wall 273 to be described later so as not to hinder the exhaust. Note that reference numeral 26
Is a mounting piece on which the tip of the wind guide lid 24 is mounted. The lower part of the wind guide lid 24 is a drying chamber 27. Side wall 271, 272 of the drying chamber 27 (272 is shown in FIG. 2, FIG. 3, and FIG. 4) at a middle height, a little near the exhaust port 23 side, a placing shelf for placing a seaweed cage Four 275 and 276, respectively, are provided in two rows above and below. The upper and lower intervals of the loading shelves 275 and 276 are appropriately set to intervals suitable for drying. On the mounting shelves 275 and 276, the holding frame 40 with the seaweed 4 attached to the upper and lower two stages is placed. Here, the holding structure of the seaweed cage 4 will be described with reference to FIGS. 1 and 2. The seaweed cage 4 from which the seaweed is extracted is attached to the holding frame 40. The holding frame 40 is a quadrangular frame body, and has two holding metal fittings 42 on each of two opposite sides. The holding metal fitting 42 is in the shape of an L plate bent upward, and the seaweed cage 4 is attached with a slight tension so that the whole seaweed cage 4 is not loosened by pushing the cage gap into the holding metal fitting 42. Then, the seaweed cage 4 is mounted in the drying chamber 27 by mounting the holding frame 40 on the mounting shelves 275 and 276. The side wall 273 on the exhaust port 23 side of the drying box 2 has a blower 3 to be described later.
The air outlet 30 is provided. The blowout port 30 is set at the height of the middle portion of the placing shelves 275 and 276 so that warm air can pass between the laver cages 4 held on the placing shelves 275 and 276 when the laver is dried. The blowout part 30 has a structure in which pipes are placed horizontally, and both ends are drying chambers.
It is bent to the 27 side and becomes outlets 31 and 32. In addition, between the outlets 31, 32, there are three outlets 33, 3 with a small diameter.
4 and 35 are provided. The side wall 277 facing the side wall 273 serves as a turn-back surface of the warm air blown out from each outlet. A blower 3 is provided adjacent to the dry box 2. The blower 3 has an electric heater and a blower (both not shown)
Is provided, and the temperature and the amount of warm air can be appropriately set. Reference numeral 36 is a suction pipe, 37 is a discharge pipe, and the discharge pipe 37 is connected to the blow-out portion 30. (Operation) The operation of this embodiment will be described with reference to FIGS. 1 to 4. Two kinds of seaweed mixed solution, which has the same amount as the dry seaweed production and slightly different in concentration from each other, is made into two seaweed cages 4 in an area larger than the standard (about 600 to 1200 cm 2 per one). The concentration of the seaweed mixed solution is empirically set so that the dry seaweed has a heavier weight within the standard and the other has a lighter weight within the standard. At this time, make sure to make the paper evenly so that no holes are formed during drying. Two pieces of seaweed 4 made from seaweed are put on a centrifuge and dehydrated to make a sample. Next, the seaweed cage 4 is attached to the holding frame 40. The seaweed cage 4 is attached by pushing the end part into the holding metal fitting 42 of the holding frame 40.
At this time, the nori cage 4 is attached with an appropriate tension so that the nori cage 4 becomes flat without slackening, waviness or excessive tension. This allows the warm air to pass smoothly over the surface of the seaweed to prevent the seaweed from peeling off and poor drying. Then, the holding frame 40 to which one seaweed cage 4 is attached is placed on the placing shelf 276 with the seaweed N side facing up, and the holding frame 40 to which the other seaweed cage 4 is attached faces the seaweed N side downward. And place it on the placing shelf 275. Next, the blower 3 is operated to send warm air of an appropriate temperature and air volume (in this embodiment, the temperature is 50 to 60 ° C., and the air volume is 1.0 to 2.0 m 3 / min), and the wind speeds at the outlets 31 and 32 are: For example, it should be 10 to 15 m / sec. The warm air blown from each outlet passes between the upper and lower laver 4 and removes water from the laver N,
Fold back at side wall 277 as indicated by the arrow in the figure. The returned warm air is discharged from the exhaust port 23 to the outside of the drying box 2 while drying while passing through the backsides of the seaweed 4 arranged above and below the drying chamber 27, and the seaweed N on the seaweed is dried. It In addition, the side leading to the exhaust port 23 of the drying chamber 27 is formed to be slightly narrow by the air guide lid 24, so that the velocity of the warm air in the drying chamber 27 is increased and the warm air easily follows the seaweed cage 4. There is. Further, the heat insulating lid 21 suppresses the dissipation of heat inside the drying box 2 to improve the thermal efficiency. According to the seaweed quick-drying apparatus 1 of this example, the standard seaweed was dried in 10 to 15 minutes, and the dry weight of seaweed in the case of the above-mentioned two kinds of concentration settings was found in a short time. Then, from the data of the concentration and dry weight of the seaweed mixture of the two samples, the concentration of the seaweed mixture of any dry weight within the standard (for example, 2.7 to 3 g, which is slightly lighter within the standard) can be easily calculated. . The present invention is not limited to the illustrated embodiment, and various modifications can be made within the scope of the claims.

大が期待できる。Since the present invention has the above configuration, it has the following effects. (A) Since the same amount of the seaweed mixed solution as in the case of producing dry seaweed is spread on the seaweed cage with an area larger than the standard size, the surface area becomes large and the thickness becomes thin, so that it can be dried more efficiently.
Moreover, since the nori surface is opposed to each other during drying and air is blown during that time, there is no waste of air blowing. (B) By increasing the drying speed of the seaweed, the dry weight of the seaweed having a certain concentration can be known in a short time, and the proper concentration of the seaweed mixed solution corresponding to an arbitrary dry weight of the seaweed can be set early. This ensures that the weight of dry seaweed can be kept within the standard range, and the occurrence of defective products due to non-weight specifications can be eliminated. In addition, there is no waste of thickening the concentration of the seaweed mixture more than necessary to escape from the lack of weight as in the past, and it is possible to obtain a larger number of dry seaweed within an appropriate weight range. Can be expected to increase.
