Description

A drying method of marine algae

More particularly, the present invention relates to a method of drying seaweeds, more particularly, seaweeds such as kelp, sea bass, and seaweeds are dried in a dryer without removing them, dried with hot air, .

Seaweeds include brown algae such as kelp, seaweed, and tortoise, red algae such as Kim, mugwort, and green algae such as green algae. Among 50 kinds of seaweeds in Korea, about 50 kinds of seaweeds are used for food. Among them, seaweeds such as seaweed, seaweed, kelp, parasites, mackerel, and hearing are enjoyed by Koreans.

Alkaline foods, seaweeds, proteins, carbohydrates, vitamins, minerals and contains a lot. Seaweeds clear blood, inhibit active oxygen production, and are rich in dietary fiber to prevent constipation, hypertension, atherosclerosis and various adult diseases, such as cancer and helps prevent the occurrence of various cancers. Iron contained in seaweed prevents anemia.

Seaweeds have chlorophyll like vegetables and grow by photosynthesis, so nutritional components are similar to vegetables. Seaweeds contain an average of 10% protein, especially about 40%. It contains taurine and vitamin A, so it has effects such as pressure, strength, anti-thrombosis, and anti-cholesterol. It also helps prevent vision and prevent night blindness. In addition, Kim is effective in reducing blood pressure, excretion of cholesterol, preventing obesity, preventing anemia. Seaweed has blood pressure reduction, osteoporosis, thyroid disease, constipation, obesity, prevention of food poisoning, anti-cancer effect and also softens the hair. Kelp may be effective to inhibit absorption of harmful heavy metals, excretion of cholesterol, prevention of constipation and obesity, protection of gastric mucosa, prevention of osteoporosis, promotion of bone growth and development, inhibition of absorption of radiation, and anticancer effect.

Seaweeds account for more than 57% of domestic seaweeds, producing more than 400,000 tons per year, and are the major producing areas of Goheung, Wando, and Captain. Until now, only seaweed, which is an edible part, is sampled at the time of harvesting seaweed, and non-seaweeds such as roots, stem, and sporophyll are marine dumping. The amount of marine excavation in the seaweed is about 160,000 tons / year, which is increasing every year.

In recent years, marine dumping of the brown seawater has been recognized as a major marine pollution source, and problems have been raised. In addition to direct marine pollution, marine dumping can cause friction between industries such as deterioration of seabed environment and damage of fishery. Especially, It generates a lot of CO ₂ on Additionally, because the risk is very high, which can be linked to air pollution by.

In recent years, studies on the utilization of the seaweed non-fermentation sites have been attempted both domestically and abroad. However, since the seaweed non-fermentation including alginic acid, etc., Or exist only as a patent. In addition, there is no actual commercialization technology because of the problem of collection, problems of drying process, absence of purification / low chloride / undifferentiation technology process, and existing commercial animal feed or aquaculture application research.

These seaweeds can be supplied as raw materials for feeds. In particular, seaweeds and kelp are the key to reducing the processing time in processing and feeding the feeds and feedstocks to the bottom.

At present, various methods such as low-speed freezing are applied for efficient drying of these algae, but there are problems in mass production and factors of increase in unit price. In order to produce low-cost feeds using algae, It is urgent to develop a method capable of drying and processing.

In this connection, various seaweed drying apparatuses having various structures such as those disclosed in Korean Utility Model Registration No. 0277921 (registered on May 28, 2002) have been developed and used. Generally, in a drying apparatus, a conveyor is installed in a drying chamber so that water contained in the drying chamber is evaporated as the steam is conveyed by the conveyor in the drying chamber, and water vapor generated in the drying chamber is conveyed by a plurality of exhaust fans And is discharged from the drying chamber.

In addition, the conventional seaweed drying method is a method using dehydration through low-speed freezing. However, since the dehydration of moisture is good, there is a limit in mass drying, and a loss of raw materials such as debris is generated by passing through a crush- There is a problem that the yield is low.

Therefore, the inventors of the present invention have conducted research to develop a method of drying and processing seaweeds at a lower unit price and a larger amount while stably drying seaweeds, and seaweeds such as kelp, sea mustard, The present inventors have completed the present invention by discovering that the seaweed can be mass-dried in a more stable and efficient manner by removing hot air, then removing the salt and drying again.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for drying algae more efficiently and efficiently.

In order to solve the above-mentioned technical problems, the present invention provides a method for drying seaweeds, comprising the steps of:

(S1) placing whole algae into the drying rails of the dryer;

(S2) hot air is injected into the dryer through the hot air supply unit, and the seaweed trapped in the drying rail in step (S1) is heated at 85 to 95 DEG C for 1 to 3 hours;

(S3) washing the steamed seaweed to remove salt and draining water through the drain port in the step S2; And

(S4) drying the seaweed from which the salt has been removed in the step (S3) at 110 to 130 DEG C for 13 to 16 hours.

In the present invention, seaweeds may be brown algae such as kelp, sea bass, and red sea bream, red algae such as seaweed, mugwort, and green algae such as red sea bream.

The method of drying seaweeds according to the present invention can be described with reference to FIGS. 1, 2 and 3.

&Lt; Example 1 >

The seaweed was dried using the seaweed drier shown in Fig.

The seaweed moved through the conveyor belt 16 is tightly seated in the seaweed digging portion 14 of the drying rail 15 provided on the upper surface of the dryer 20 as a whole.

Then, hot air is injected into the dryer through the hot air supply unit 12, so that the seaweed trapped on the drying rail 15 is moved for 2 hours at 90 ° C. At this time, the boiling process proceeds only by the own water of the seaweed, and 20-30% of the water falls to the bottom as the destruction of the cell membrane of the seaweed proceeds. The moisture that has fallen on the floor through this process is drained through the drain port 10 located on the lower surface of the dryer 20 and the generated harmful gas is exhausted through the exhaust section 11 located on the other surface of the dryer 20.

Then, the seaweed was steamed through the fresh water pipe 17 provided at the upper part of the dryer 20 to spray the fresh water from the top to the bottom using a sprinkler, which is a water injection port, to remove the salt remaining in the seaweed. At this time, the removed salt and the used fresh water were drained through the drain port (10).

Then, the seaweeds from which the salt was removed were dried at 120 ° C for 16 hours to obtain dried seaweeds.

According to the seaweed drying method of the present invention, drying time can be as long as about one week in the case of the conventional natural drying. Also, even when the seaweed was completely dried, the drying efficiency could be obtained at a level comparable to the case where the seaweed was cut and dried.

According to the present invention, it is possible to reduce manpower without cutting, freezing, washing, and other steps, and it is possible to eliminate risk factors such as blade damage due to foreign substances such as stones during cutting. In addition, it can be mass-dried according to the expansion of the drying facility, and can be dried at night after setting the raw material in the daytime, thereby saving manpower.
