Seaweed treatment method including semi-drying shrinkage process and seaweed treatment system therefor {SEAWEED TREATMENT METHOD INCLUDING SEMI-DRYING SHRINKAGE PROCESS AND SEAWEED TREATMENT SYSTEM THEREFOR}

The present invention relates to a seaweed treatment system, and in particular, the seaweed is more easily processed by introducing a semi-drying shrinkage process separate from the drying process so that the seaweed can be contracted over a sufficient time while reducing the time to clean the seaweed. The present invention relates to a method for treating seaweed suitable for having the color and thickness having the best marketability, and a seaweed treatment system for the same.

In general, seaweeds include brown algae such as kelp, seaweed, and tot, red algae such as laver and agaric, and green algae such as green algae. Of the 500 species of seaweed inhabiting Korea, more than 50 species are used for food, and among them, seaweed, seaweed, kelp, green seaweed, tot, majaban, and hearing are favorite seaweeds.

Algae, an alkaline food, contains a lot of protein, sugar, vitamins, and minerals. Seaweed clears the blood, suppresses the production of free radicals, is rich in dietary fiber, is good for preventing constipation, and helps prevent various adult diseases such as high blood pressure and arteriosclerosis and various cancers such as bowel cancer. The iron contained in seaweed prevents anemia.

Seaweed has chlorophyll like vegetables and grows through photosynthesis, so its nutritional content is similar to that of vegetables. Seaweed contains about 10% protein on average, and especially seaweed contains 40%. Seaweed contains taurine and vitamin A, so it has effects such as coercion, strong heart, anti-thrombosis, and anti-cholesterol, and helps protect eyesight and prevent night blindness. In addition, Kim Eun is effective in reducing blood pressure, excreting cholesterol from the body, preventing obesity, and preventing pernicious anemia. Seaweed reduces blood pressure, osteoporosis, thyroid disease, constipation, obesity, food poisoning prevention, anti-cancer effect, and also softens hair. Kelp inhibits the absorption of harmful heavy metals in the body, excretes cholesterol from the body, prevents constipation and obesity, protects the gastric mucosa, prevents osteoporosis, promotes bone growth, inhibits radiation absorption in the body, and has anticancer effects.

These seaweeds are dried by a drying device. In a conventional drying device, moisture is evaporated as seaweeds are transported from the drying unit by a conveyor, and water vapor generated from the drying unit is transferred to a plurality of exhaust fans arranged along the conveying path of the conveyor. To be discharged.

However, as in the prior art, the method to be transported through a conveyor has a problem that it is inconvenient and time-consuming to care for seaweed, and the processing speed may be fast because it is dried by instantaneous hot air drying, but it is naturally dried without sufficient shrinkage. Compared to the method, there was no choice but to obtain a product with lower color and thickness.

<Example>

1 is a configuration diagram illustrating a seaweed treatment system according to an embodiment of the present invention, and FIG. 2 is a reference diagram showing a first trimming unit in which a work on seaweed is started in the seaweed treatment system according to the embodiment of the present invention. .

As shown, the seaweed treatment system according to the embodiment of the present invention includes a first care unit 10 and a second care unit 20, a seawater washing unit 30, an air dewatering unit 40, and a semi-dry contraction unit. (50), the primary processing unit 60, the drying unit (not shown), the packaging unit 80, and seaweed by a configuration consisting of a line-type transfer rail 110 for transporting the seaweed to each of these parts Because it can be cleaned while transporting it in an upright state, the processing speed of workers is very fast, and the seaweed is folded or cut by introducing a semi-dry shrinking process separate from the drying process so that the seaweed can be sufficiently shrunk. Tea processing is easy, so the processing quality is excellent, and the color and thickness of seaweed are suitable, so that it has high marketability.

Hereinafter, a seaweed treatment system according to an embodiment of the present invention will be described in detail with reference to the respective components.

The transfer rail 110 is provided in a line shape to minimize installation space and installation cost, and the first care unit 10 and the second care unit 20, seawater washing unit 30, and air dewatering unit (40), the semi-dry contraction portion 50, the primary processing portion 60 is connected in a circulating manner. In addition, the transfer rail 110 is installed at a height spaced upward from the indoor floor according to the manual height based on when the worker is standing and working. And, as shown in the enlarged portion of FIG. 2, a plurality of hooks 111 are provided that are transferred along the transfer rail 110. As a result, the seaweed can be transported along the transport rail 110 by hanging it on the hook 111.

A point to note about the configuration of the transfer rail 110 is that it is possible to trim the algae in the erected state while the workers are standing. In this way, if the seaweed can be cleaned while being erected by the transfer rail 110, rather than the general method of working by laying it on a conveyor belt, the working speed is dramatically improved because it is not necessary to work while rotating the seaweed without interference from the bottom surface. do. In the case of the general method of laying seaweeds laid down, the installation cost increases (2.5 times or more) as the facility area to lay them down increases, and more installation space is required.

In the first care unit 10 and the second care unit 20, the roots and tails of seaweeds transported along the transfer rail 110 are trimmed and removed. Since the roots and tails of seaweed are not normally edible, they are separated from the body and removed.

The seawater washing unit 30 is washed by spraying seawater on seaweeds whose roots and tails have been trimmed in the care unit. To this end, a plurality of seawater spray nozzles 31 for spraying seawater are installed in the seawater washing unit 30. In the case of seaweed, it is selected from the raw material directly transported from the sea, so many sea creatures (green or copepods, etc.) are attached to the surface, so it is washed by spraying high pressure seawater from the top to the bottom.

The air dewatering unit 40 dehydrates the moisture on the surface of the seaweed by spraying air onto the seaweed washed by the seawater washing unit 30. To this end, the air dewatering unit 40 is provided with a plurality of air injection nozzles 41 capable of injecting air similar to a shower facility.

The semi-dry contraction unit 50 is for performing the semi-drying and contracting process while maintaining a certain condition with a sufficient time for the seaweed dehydrated by the air dewatering unit 40, and is provided as a contraction chamber having a separate room. To this end, the first step of introducing fresh air into the interior, the second step of heating the air inside the semi-dry contraction unit 50, the interior temperature of the semi-dry contraction unit 50 is maintained at 30~40℃ and 2000㎥/ The third step of semi-drying and contracting seaweed while circulating air under the condition of air volume of min and wind pressure of 80mm/Aq, and the fourth step of dehumidifying when the internal humidity exceeds the set humidity are repeated in a circulating manner and gradually seaweed It shrinks by semi-drying to 50% moisture content. At this time, when the third step proceeds, the initial humidity of the semi-dry contraction unit 50 starts at 27 to 33%, and when the humidity exceeds 45%, the fourth step is set to proceed.

The time for semi-drying and contracting the seaweed in the semi-dry contraction part 50 is at least 4 to 8 hours so that it can be contracted for a sufficient time. As a result, the width and enlargement of the seaweed gradually decrease by 50% or more, and the moisture content reaches the level of 50%, resulting in a semi-dry state. As described above, when the seaweed is gradually contracted to a sufficient level without excessive heat in the semi-dry contraction part 50, the original color is maintained without discoloration. For example, kelp is a brown algae that has the property of turning green when heat is applied. The dried dried seaweed is a product that has a black color and has a thick thickness. The kelp that has undergone a process of gradually sufficiently shrinking through the semi-dried contraction unit 50 has a black color and does not lose its best product value.

In the primary processing unit 60, a process of cutting or folding seaweed that has been contracted in a semi-dry state by the semi-dry contraction unit 50 is cut or folded for commercialization. From the first processing unit 60, the seaweed is lifted from the transfer rail 110, processed, and then laid on a first conveyor belt 61 and transferred. If more workers are needed, the seaweeds are lifted from the transfer rail 110, transferred to the first conveyor belt 61, laid down, and transferred while each workers share and perform the primary processing. In this regard, seaweeds are mainly cut or folded products, but if such a process is performed in a completely dried state, the seaweeds are easily crushed and the loss rate is enormous. However, in the case of seaweed from the shrinkage chamber, it is semi-dried with a moisture content of around 50%, so it does not crumble when folded or cut, and the cross section comes out clean, so the best product value is not lost.

In the drying unit (not shown), the first processed seaweed is heated by hot air at a temperature of 70° C. or higher to completely dry it to a moisture content of about 10%. In the case of seaweed dried in the drying unit, it is already dried in a semi-dried state with a sufficient time in the semi-drying and contracting unit 50, so unlike the case of hot air heating from the beginning, the unique color of seaweed can be saved, and the thickness is relatively You can keep it thick.

In the packaging unit 80, the seaweeds dried in the drying unit are moved, subjected to secondary processing if necessary, and then packaged and commercialized. In the case of secondary processing, depending on the product, it may be done with simple care, or it may be a more detailed cutting or folding process. For secondary processing and packaging, a second conveyor belt 81 may be installed in the packaging unit 80, and the dried seaweeds are laid on the second conveyor belt 81 and then transported, while each worker shares the secondary processing and Proceed with packaging.

Subsequently, a description will be given of a seaweed treatment method that proceeds using the seaweed treatment system described above.

However, FIG. 3 is a flowchart illustrating a method for treating seaweed according to an embodiment of the present invention, and FIG. 4 is a flowchart illustrating a detailed process of the semi-drying and shrinking step of FIG. 3.

Seaweed treatment method according to an embodiment of the present invention, as shown in Figure 3, sorting and laying step (S110), root trimming step (S120), tail trimming step (S130), seawater washing step (S140), air dehydration Step (S150), semi-drying and shrinking step (S160), the first processing step (S170), hot air drying step (S180), secondary processing and packaging step (S190).

In the sorting and laying step (S110), non-growing seaweeds among the collected raw materials are thinned out, only seaweeds suitable for commercialization are selected, and those attached to one root are separated. The seaweed selected in this way hangs the upper end of the hook 111 of the transfer rail 110. Then, by the line-type transfer rail 110 installed at a certain height spaced from the indoor floor upwards, the seaweed is erected and spread at an appropriate height for the workers to handle manually.

In the root trimming step (S120), the first trimming unit 10 cleans and removes the root of the seaweed.

In the tail trimming step (S130), the seaweed from which the root portion has been removed in the first trimming unit 10 is removed by trimming the tail portion. This leaves only the portion of the algae that can be consumed as food.

In the seawater washing step (S140), the seaweed trimmed in the previous step is transferred to the seawater washing unit 30 to remove foreign substances by sprayed seawater. The seawater washing unit 30 is equipped with a seawater spray nozzle 31 that injects seawater at high pressure, and removes foreign substances such as sea creatures (green algae or copepods) attached to the surface of seaweed by spraying high pressure seawater from top to bottom. You can do it.

In the air dehydration step (S150), air is sprayed from the air dehydration unit 40 to the air jet nozzle 41 on the seaweed washed in the previous step to dehydrate the water on the surface of the seaweed. To this end, the seaweed is transferred to the air dewatering unit 40 and an air injection nozzle 41 installed therein. To this end, the air dewatering unit 40 is provided with a plurality of air injection nozzles 41 capable of injecting air similar to a shower facility, thereby removing moisture from algae while injecting high-pressure air.

In the semi-drying and shrinking step (S160), the seaweed dehydrated by the air dewatering unit 40 is transferred to the shrinking chamber, and the semi-drying and shrinking process is performed while maintaining a certain condition for a sufficient time. To this end, as shown in FIG. 4, a first step of introducing fresh air into the interior (S161), a second step of heating the air inside the semi-dry contraction unit 50 (S162), and the semi-dry contraction unit 50 The third step (S163~S164) of semi-drying and contracting seaweed while circulating air under conditions of an air volume of 2000㎥/min and a wind pressure of 80mm/Aq while maintaining an internal indoor temperature of 30~40℃, internal humidity set humidity If it exceeds, the fourth step (165 to S166) of condensing and removing the evaporated moisture is repeated in a cyclic manner, and the seaweed is gradually semi-dried to a moisture content of 50% and contracted. At this time, when the third step proceeds, the initial humidity of the semi-dry contraction unit 50 starts at 27 to 33%, and when the humidity exceeds 45%, the fourth step is set to proceed. In this way, the seaweed is semi-dried and contracted for 4 to 8 hours so that it can be contracted with sufficient time. As a result, the width and enlargement of the seaweed gradually decrease by 50% or more, and the moisture content reaches the level of 50%, resulting in a semi-dry state. As described above, when the seaweed is gradually contracted to a sufficient level without excessive heat in the semi-dry contraction part 50, the original color is maintained without discoloration.

In this way, the time for semi-drying and shrinking seaweed is 4 to 8 hours so that it can be semi-dried and contracted for a sufficient time. As a result, the width and enlargement of the seaweed gradually decrease by 50% or more, and the moisture content reaches the level of 50%, resulting in a semi-dry state. As described above, when the seaweed is gradually contracted to a sufficient level without excessive heat in the semi-dry contraction part 50, the original color is maintained without discoloration.

In the first processing step (S170), a process of cutting or folding the seaweed contracted in a semi-dried state in the previous step for commercialization in the first processing unit 60 is performed. In this regard, if the seaweed is cut or folded in a completely dried state, it is easily broken and the loss rate is enormous. However, in the case of seaweed that has been semi-dried with a moisture content of around 50% through the previous step, it does not crumble when folded or cut, and the cross section comes out clean, so that the best product value can be maintained.

In the hot air drying step (S180), the first processed seaweed is heated by hot air at a temperature of 70° C. or higher in a drying unit to completely dry the water content of about 10%. In the case of the dried seaweed, it is already dried in a semi-dried state with sufficient time in the previous step, so unlike the case of hot air heating from the beginning, the unique color of the seaweed can be saved, and the thickness can be maintained relatively thick.

In the second processing and packaging step (S190), the seaweed dried in the previous step is optionally subjected to secondary processing if necessary, and then packaged and commercialized. This completes the entire process of the seaweed treatment method according to the embodiment of the present invention. Here, in the case of secondary processing, depending on the product, it may be finished with simple care, or it may be a more detailed cutting or folding process.

Although the preferred embodiment of the present invention has been described above, the present invention can use various changes, modifications, and equivalents. It is clear that the present invention can be applied in the same manner by appropriately modifying the above embodiments. Therefore, the above description does not limit the scope of the present invention determined by the limits of the following claims.
