Seaweed treatment method including semi-dry 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, in particular, it is possible to shorten the time to clean the seaweed, but it is easier to process the seaweed by introducing a semi-dry shrinkage process separate from the drying process so that the seaweed can shrink over a sufficient time. And it relates to a suitable seaweed treatment method and a seaweed treatment system for it to have a color and thickness with the best productability.

In general, seaweeds include brown algae such as kelp, seaweed, and seaweed, red algae such as seaweed and seaweed, and green algae such as green onion. Of the 500 species of seaweed inhabited in Korea, about 50 species are used for food, among which seaweed, seaweed, kelp, green, green, majaban, and auditory is a favorite seaweed.

Seaweed, an alkaline food, contains many proteins, sugars, vitamins, and minerals. Seaweed clears the blood, suppresses the production of free radicals, and is rich in dietary fiber, which is good for preventing constipation, and helps to prevent various cancers such as high blood pressure, arteriosclerosis, and various adult diseases and bowel cancer. Iron in seaweed prevents anemia.

Seaweed has chlorophyll like vegetables and grows by photosynthesis, so its nutritional properties are similar to vegetables. Seaweed contains about 10% of protein on average, especially seaweed contains about 40%. The seaweed contains taurine and vitamin A, so it has the effects of coercion, heartburn, antithrombosis, and anti-cholesterol, and also helps protect eyesight and prevent night blindness. In addition, Kim is effective in reducing blood pressure, excreted cholesterol, preventing obesity, and preventing malignant anemia. Seaweed has blood pressure reduction, osteoporosis, thyroid disease, constipation, obesity, food poisoning prevention, anti-cancer effect, and also softens hair. Kelp has the effect of suppressing the absorption of harmful heavy metals into the body, shedding extracorporeal cholesterol, preventing constipation and obesity, protecting the gastric mucosa, preventing osteoporosis, promoting the growth and development of bone, suppressing the absorption of radiation into the body, and anticancer effects.

These seaweeds are dried through a drying device. In a conventional drying device, water is evaporated while the seaweeds are transferred from the drying unit by a conveyor, and water vapor generated in the drying unit is applied 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 of conveying through the conveyor has a problem that it is inconvenient and takes a lot of time to clean the seaweed, and because it is dried by instantaneous hot air drying, the processing speed may be fast, but it may not be sufficiently contracted and naturally dried. Compared to the method, it was inevitable to obtain a product with a lower color and thickness.

<Example>

1 is a configuration diagram for explaining a seaweed treatment system according to an embodiment of the present invention, Figure 2 is a reference diagram showing a first trimming unit for the operation of the seaweed in the seaweed treatment system according to an embodiment of the present invention .

As shown, the seaweed treatment system according to an embodiment of the present invention includes a first trimming section 10 and a second trimming section 20, a seawater washing section 30, an air dehydration section 40, and a semi-dry shrinkage section. (50), a primary processing unit 60, a drying unit (not shown), a packaging unit 80, and a seaweed by a configuration consisting of a line-type transfer rail 110 for transporting seaweed to each of these parts Because it can be trimmed while transporting in a standing state, the processing speed of workers progresses very quickly, and a seaweed is folded or cut by introducing a semi-dry shrinkage process separate from the drying process so that the seaweed can be sufficiently shrunk 1 It is easy to process tea, so it has excellent processing quality and suitable color and thickness of seaweed, so it has high commerciality.

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

The transport rail 110 is provided in a line form so as to minimize installation space and installation cost, and the first trimming part 10 and the second trimming part 20, the seawater washing part 30, and the air dewatering part (40), the semi-dry shrinkage portion 50, the primary processing portion 60 is connected in a cyclic manner. In addition, the transfer rail 110 is installed at a height spaced upward from the indoor floor in accordance with the height of the manual work based on when the worker stands and works. And as shown in the enlarged portion of Figure 2 is provided with a plurality of hooks 111 to be transported along the transport rail (110). In this way, the seaweed can be transported along the transport rail 110 in the form of a hook on the hook 111.

Note that the configuration of the transport rail 110 is that it is possible to trim the seaweed in a standing state while workers are standing. As such, if the seaweed can be trimmed in a state erected by the conveying rail 110 rather than the normal way of laying the seaweed on a conveyor belt, the work speed is dramatically improved because there is no need to work while turning the seaweed without interference from the bottom surface. do. In the general way of laying and processing seaweeds, the installation area for laying them increases, and installation costs are high (2.5 times or more) and more installation space is required.

In the first trimming part 10 and the second trimming part 20, the root and tail parts of the seaweeds transferred along the transport rail 110 are trimmed and removed. In the case of the roots and tails of seaweeds, they are usually not edible, so they are removed from the body.

The seawater washing part 30 is washed by spraying seawater on the seaweeds whose roots and tails are trimmed from the trimmed parts. To this end, a plurality of seawater injection nozzles 31 for spraying seawater are installed in the seawater washing unit 30. In the case of seaweed, it is selected from the raw materials that have been transferred directly from the sea, and it is washed by spraying high-pressure seawater from the top to the bottom because there are many sea creatures (such as blues and copepods) on the surface.

The air dewatering unit 40 sprays air to the seaweeds washed in the seawater washing unit 30 to dehydrate the water on the surface of the seaweeds. To this end, the air dehydration unit 40 is provided with a plurality of air injection nozzles 41 that allow air to be injected similarly to a shower facility.

The semi-dry shrinkage unit 50 is for performing a semi-drying and shrinking process while maintaining a predetermined condition for a sufficient time for the seaweed dehydrated in the air dehydration unit 40 and is provided as a shrinking chamber having a separate room. To this end, the first step of introducing fresh air therein, the second step of heating the air inside the semi-dry shrinkage section 50, the indoor temperature of the semi-dry shrinkage section 50 is maintained at 30~40℃ and 2000㎥/ The 3rd step of semi-drying and shrinking the seaweed while circulating air under the condition of the air volume of min and the wind pressure of 80mm/Aq. And shrinks by semi-drying up to 50% water content. At this time, when the third stage proceeds, the initial humidity of the semi-dry shrinkage portion 50 starts at 27 to 33% and is set to proceed to the fourth stage when the humidity exceeds 45%.

The time for the seaweed to be semi-dried and contracted in the semi-dry shrinking part 50 is at least 4 to 8 hours so that it can contract for a sufficient time. As a result, the width and hypertrophy of seaweed gradually decreases by 50% or more, and the water content reaches 50%, resulting in a semi-dry state. As described above, when the seaweed is gradually contracted to a sufficient level in a state in which the seaweed is not excessively heated in the semi-dry shrinkage part 50, it does not discolor and maintains its original color. For example, kelp is an original brown algae that has a property of turning green when heat is applied. The dried and dried gandamashi is black and has a thick thickness, but the kelp that has undergone a process of gradually shrinking through the semi-dry shrinkage portion 50 is black and does not lose its best product value.

In the first processing unit 60, a process of cutting or folding seaweeds contracted in a semi-dry state in the semi-dry shrinkage unit 50 for commercialization is performed. From the primary processing unit 60, seaweed is taken out from the transport rail 110, processed, and transported while lying on a first conveyor belt 61. If more workers are needed, the seaweeds are lifted from the transport rail 110 and then transferred to the first conveyor belt 61 and then transported, whereby each worker distributes the seaweed to perform primary processing. In this regard, seaweed mainly cuts or folds many products. If this process is performed in a fully dried state, the seaweed is easily broken and the loss rate is huge. However, in the case of seaweed from the shrinkage chamber, it is a semi-dry state with a water content of about 50%, so it does not break when folded or cut, and the cross section comes out clean, so it does not lose the best product value.

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

In the packaging section 80, the dried seaweed is transferred from the drying section to perform secondary processing, if necessary, and then packaged to commercialize it. In the case of secondary processing, depending on the product, it may be done simply with care, or it may be a more detailed cutting or folding process. For the second processing and packaging, a second conveyor belt 81 may be installed in the packaging unit 80, and each worker may share the second processing and transfer while laying and transporting dried seaweed on the second conveyor belt 81. Proceed with packaging work.

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

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

Seaweed treatment method according to an embodiment of the present invention, as shown in Figure 3 screening and erecting step (S110), rooting step (S120), tailing step (S130), seawater washing step (S140), air dehydration It includes a step (S150), a semi-dry shrinking step (S160), a first processing step (S170), a hot air drying step (S180), a second processing and packaging step (S190).

In the screening and erecting step (S110), non-growing seaweed is removed from the collected raw materials, and only seaweed suitable for commercialization is selected, and those attached to one root are separated. The selected seaweed hangs the upper end on the hook 111 of the transport rail 110. Then, the seaweed is erected at an appropriate height that workers can stand and manually handle by the line-type transfer rail 110 installed at a predetermined height spaced upward from the indoor floor.

In the rooting step (S120), the root portion of the seaweed is trimmed and removed in the first trimming portion 10.

In the tail trimming step (S130), the tail portion is trimmed and removed with respect to the seaweed having the root portion removed from the first trimming portion 10. This leaves only the portion of the seaweed 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 seawater. The seawater washing unit 30 is provided with a seawater spraying nozzle 31 for spraying seawater at high pressure to remove foreign substances such as sea creatures (blue or copepods) attached to the surface of seaweed by spraying high-pressure seawater from top to bottom. I can do it.

In the air dewatering step (S150), air is jetted from the air dewatering unit 40 to the air jet nozzle 41 in 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 the air injection nozzle 41 installed therein. To this end, the air dehydration 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 seaweed while spraying high pressure air.

In the semi-dry shrinkage step (S160), the seaweed dehydrated in the air dehydration unit 40 is transported to the shrinkage chamber, and a semi-drying and shrinking process is performed while maintaining a predetermined condition for a sufficient time. For this, as shown in FIG. 4, the first step (S161) for introducing fresh air therein, the second step (S162) for heating the air inside the semi-dry shrinkage part (S162), and the semi-dry shrinkage part (50). The third step of semi-drying and shrinking the seaweed while circulating air under conditions of maintaining an indoor room temperature of 30~40℃ and circulating air under a condition of air volume of 2000㎥/min and wind pressure of 80mm/Aq (S163~S164), humidity set with internal humidity When it exceeds, the fourth step (165 to S166) of condensing and removing the evaporated water is repeated in a cyclic manner, and the seaweed is gradually shrunk by half drying to a water content of 50%. At this time, when the third stage proceeds, the initial humidity of the semi-dry shrinkage portion 50 starts at 27 to 33% and is set to proceed to the fourth stage when the humidity exceeds 45%. As such, the time for seaweed to shrink by semi-drying is 4 to 8 hours, so that it can be shrunk over a sufficient time. As a result, the width and hypertrophy of seaweed gradually decreases by 50% or more, and the water content reaches 50%, resulting in a semi-dry state. As described above, when the seaweed is gradually contracted to a sufficient level in a state in which the seaweed is not excessively heated in the semi-dry shrinkage part 50, it does not discolor and maintains its original color.

As such, the time for the seaweed to be semi-dried and shrunk is 4 to 8 hours, so that it can be shrunk semi-dry for a sufficient time. As a result, the width and hypertrophy of seaweed gradually decreases by 50% or more, and the water content reaches 50%, resulting in a semi-dry state. As described above, when the seaweed is gradually contracted to a sufficient level in a state in which the seaweed is not excessively heated in the semi-dry shrinkage part 50, it does not discolor and maintains its original color.

In the first processing step (S170), the seaweeds contracted in a semi-dry state in the previous step are cut or folded for commercialization in the first processing unit 60. In this connection, when the seaweed is completely dried and cut or folded, it is easily broken and the loss rate is huge. However, in the case of seaweed, which has been semi-dried at around 50% water content through all steps, it is possible to maintain the best product value because the cross-section is clean and not broken when folded or cut.

In the hot air drying step (S180), the primary processed seaweed is heated by hot air at a temperature of 70° C. or higher in the drying unit to completely dry the water content to about 10%. In this case, the dried seaweed has been 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 preserved and a relatively thick state can be maintained.

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. Thus, the entire process of the seaweed treatment method according to the embodiment of the present invention is completed. 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 embodiments of the present invention have been described above, the present invention can use various changes, modifications, and equivalents. It is clear that the present invention can be equally applied by appropriately modifying the above embodiments. Accordingly, the above description is not intended to limit the scope of the present invention as defined by the following claims.
