Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a seaweed manufacturing device.

(B) Conventional technology Conventionally, a seaweed manufacturing device (see Figure 6) has been used to transport 1 liter of seaweed (A) with raw seaweed made by a papermaking device into a drying room.
It is fed into the drying chamber in an upright position from one end of the drying chamber (0), and then reciprocated along the conveyance path (c) built vertically within the drying chamber (0).
It was designed to dry raw seaweed during the cycle to produce dried seaweed products.

(c) Problems that the invention seeks to solveHowever,
When drying seaweed, there is first a constant rate drying period during which the free water attached to the surface of the seaweed leaves evaporates, and during this constant rate drying period, the heat of evaporation is large, so drying is performed using relatively high-temperature hot air. The temperature of raw seaweed does not rise much even when dried, and there is no risk of quality deterioration even if it is rapidly dried. Next, there is a transition to a decreasing rate drying period, and during this decreasing rate drying period, the water inside the nori leaf oozes out to the leaf surface and evaporates, so as the water content in the nori leaf decreases, the water content decreases. The evaporation rate decreases, and if rapid drying is carried out using high-temperature hot air during this period, only the surface of the seaweed will become over-dried and the temperature of the raw seaweed will rise, resulting in quality deterioration, especially after the drying process. This means that the water that remains inside the body oozes out, causing the dried seaweed product to lose its luster. Therefore, during this drying period, slow drying must be carried out at a relatively low temperature. However, in the conventional drying chamber (Fig. ! ! The inlet of N (e) and the outlet of N (e) to which the dried product dried seaweed is attached are located above and below, and the hot air for drying is distributed in the vertical direction, so the flow of one dry hot air is During constant rate drying and reduction
Since seaweed tubes with different drying conditions are mixed together, it would take a long time to manufacture if drying was done with low-temperature hot air for lapse rate drying to maintain the quality of the seaweed, so it is necessary to try to shorten the manufacturing time. However, the disadvantage was that the quality deteriorated.

In addition, since the drying air flows parallel to the nori cylinder, in a drying room with a conventional structure, the drying room is turned upside down only once, so the part of the fresh nori located upwind is dried faster. However, there are disadvantages in that defects such as peeling from the lining, shrinkage, cracking, and clouding occur.

(d) Means for solving the problem In the first method, the drying section is divided into two, and a transfer section is installed between each drying chamber to transfer the cylinder frame without turning the machine frame upside down. It is an object of the present invention to provide a seaweed manufacturing apparatus which is configured to interpose a cylindrical frame from a constant rate drying chamber to a decreasing rate drying chamber and transfer the frame while vertically inverting the frame.

(E) Function/Effect In this invention (see Fig. 1), the fresh seaweed that has become more delicate first enters one of the drying chambers (a), where it is dried with relatively high temperature drying air. Constant rate drying is carried out, and during the same drying, the seaweed cylinder is turned over -F for the first time at the folded part (b) at the end of the same room, and uniform constant rate drying is performed over the entire surface of the raw seaweed. The tray is transferred to the other drying chamber (C) and enters the same chamber, but a second vertical inversion is performed at this transfer section (d), and then a third inversion is performed at the end of the same chamber (e). The raw seaweed is turned upside down three times in total, and the dried seaweed is evenly dried.

In particular, by dividing the drying section (B) into two, drying air at the optimum temperature for careful and lapse rate drying, which is controlled by the respective heat sources (f) and (g>), can be delivered to each drying room (a) and (c).
Since the dry seaweed can be fed to the dry seaweed, it is possible to reduce the production time while maintaining the quality of the seaweed, and by turning the seaweed upside down three times in total, the above defects can be prevented and high quality dried seaweed can be manufactured. It is.

(F) Embodiment A detailed description of an embodiment of this invention based on the drawings is given below (△
) indicates the dried seaweed manufacturing equipment, machine frame (1) endless chain (
2) is suspended and the machine frame is stretched with seaweed cylinders in 2).
) is conveyed in a circulation manner, fresh seaweed is adhered to the upper surface of the seaweed space using the papermaking frame (5) of the papermaking device (4) disposed on the conveyance path of the freezing frame (3), and then The raw seaweed is dehydrated by pressing the sponge (7) of the dehydrator (6), and the machine frame (3) holding the paper-made and dehydrated poems of beef is transferred to the drying section by an endless chain (2). (B) is transported to the approximate center of the
The drying section (1
3) is inherited by the drying chain (8) of the constant rate drying chamber (a) which is one of the drying chambers disposed on the other side.

The drying section (B) is one of the drying chambers on the right side approximately in the center where the delivery section (d) is located. (a>) and the other drying chamber on the left (C), and the drying chain (8) is pivoted at the left and right ends of the constant rate drying chamber (a). It is suspended between sprockets,
The cylindrical frame (3) is held in an upright state by support blades installed on the chain (8), and transported in six directions in the lower part of the same chamber (a). 〉Performs the first vertical inversion and is transported toward the same room (a> left end, during which time,
Same room (a> constant rate dry heat source flowing from bottom to top inside) (9
The drying air from ) evaporates the free water on the outside of the fresh seaweed leaves and on the seaweed tube, and during this time drying is carried out at a constant rate with an almost constant rate of moisture blackening. During constant rate drying, the consumption of heat of evaporation is large, so even if relatively high-temperature drying air is used, the upper limit of the temperature of raw seaweed is small. There is also no negative impact on the quality of the seaweed product.

The cylinder frame (3) that has been subjected to constant rate drying is carried into the decreasing rate drying chamber (C) on the left side of the drying section <8) via the delivery section (d).

In the lapse rate drying chamber (C), a lapse rate drying chain (10) is suspended from sprockets pivotally supported at the left and right ends of the chamber (C), and the cylindrical frame (3) is erected by the support blades of the chain (10). The configuration is such that the transfer section (d)
), the right end of the delivery chain (11) is placed close to the left end of the constant rate drying chain (8), and
The left end of the reduction rate drying chain (10) is arranged close to the outside of the right end support blade rotation locus of the same chain (11).
A locking body (12) protruding from the outer periphery of the cylinder frame (3) is configured to feed the cylinder frame (3) between the support blades of the reduction rate drying chain (10). In particular, during this transfer operation, the cylinder frame (3)
Since the portion located on the upper side during constant rate drying is fed into the protrusion of the support blade of the decreasing rate drying chain (10), the second vertical inversion of the cylinder frame (3) is performed here.

The cylinder frame (3) that has entered the lapse rate drying chamber (C) is transported to the left along the upper part of the same chamber (C), and is turned upside down for the third time while being turned back at the left end of the same chamber (C). The endless chain (2) passes from the right end of the same room (C) through the delivery section (d), and a peeling device (13) peels the dried seaweed from the cage to produce dried seaweed as a product.

In this waning rate drying chamber (C), the moisture inside the leaves of raw seaweed oozes out through the cell membrane of the leaves, so the evaporation rate decreases as the moisture content of the leaves decreases. If high-temperature drying air is used at this point, the temperature of the raw seaweed will rise due to the low consumption of evaporative heat, impairing its quality, and it will also overdry only the surface layer of the raw seaweed, inhibiting moisture leaching. This will cause the inside to dry out, which will cause it to dry at a later date.
The surface of the seaweed product loses its luster due to internal moisture seeping out, and furthermore, overdrying causes cracks and peeling from the seaweed cylinder. Therefore, relatively low temperature drying air is fed into the lapse rate drying chamber (C) from the lapse rate drying heat source (14). In addition, (15) in the figure is a conveyor for carrying out the product seaweed,
(16) and (17) are dry air guide plates, (18) respectively.
(19) and (20) are the guide for the cylinder frame (3) and (2), respectively.
1) and (22) are sprockets provided at the bent portions of the endless chain (2), and (23) is a sprocket for adjusting the length of the chain (2).

As described above, in the present invention, the fresh seaweed made into paper is evaporated from the surface of the leaf by relatively high temperature drying air in the constant rate drying chamber (a), and then in the lapse rate drying chamber (C). In this method, lapse rate drying is performed using relatively low-temperature drying air.
Each drying room (a) (C) has an independent drying heat source (
9) (14), the temperature of the drying air can be freely adjusted independently, and the cylinder frame (3) is turned upside down a total of three times during the drying process. This makes it possible to maintain quality while reducing the time required for drying.

d) is divided into a constant rate drying chamber (a) and a decreasing rate drying chamber (C), and the cylinder frame (3) passes under the right side of the drying section (B). ). Note (2
4) shows a thermal insulation box made of dried dry seaweed. In particular, the one in FIG. 4 also serves as a drip-proof box because the cylindrical frame immediately after papermaking passes over the dried cylindrical frame (3).
