すれば品質が低下づるという欠点があった。(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.

を生ずるという欠点があった。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.

海苔製造装置を提供往んとするものである。(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.

る。(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.

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.

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.

２回目の筒枠（３）の上下反転が行われる。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.

品の乾海苔とするものである。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.

さ調整のためのスプロケットを示す。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,

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 (
