In general, deep-sea water is below 200m depth that sunlight does not reach. These deep-sea water have been germ-free, low temperature (about 2 ℃ ~ 9 ℃) and high pressure for thousands of years. Minerals and various essential trace elements are abundantly dissolved. These minerals and various trace elements are known to contain a component that inhibits diseases such as diabetes, hypertension and cancer by maintaining the balance of minerals essential for the human body.

In case of deep sea water, it is possible to take water using the water intake and intake pipe only in the area where the deep sea water of 200m or less exists within 5㎞ from the coastline. If the water depth of 200m or less is separated from the beach by 5km or more, And require special intake pipes to withstand high water pressures occurring at high depths.

On the other hand, sea salt is obtained by refining salt contained in seawater. About 97% of water can be removed from seawater and about 3% of salt can be obtained.

The method of obtaining salt from seawater has been widely used. It is a method of extracting crystals of salt by evaporating and concentrating only sunshine and wind power by attracting seawater to salt trough.

This method has a disadvantage in that the productivity may be deteriorated because it is affected by the weather. In order to overcome these disadvantages, it is also possible to heat concentrated salt water obtained from the salt water or electrolyze the sea water to extract the crystals of the salt.

In addition, it is difficult to secure a tidal wave by the development of a coastal area, and in order to produce salt in a tidal wave, a lot of labor is consumed.

As a result of the above problems, the production amount of natural salt is decreasing year by year, and the reduction and the reduction of the natural salt have been developed in an apparatus and a method for producing salt which is artificially similar to natural salt in order to supplement natural salt.

As a representative example, a method disclosed in "Japanese Patent Publication No. 63-27290" discloses a method of manufacturing salt by an electrical method using seawater from a factory and using an ion exchange resin film.

However, the salt produced by the above-mentioned method has a very low content of ingredients beneficial to humans as compared with natural salt, and the content of components such as calcium, magnesium and minerals necessary for the human body is remarkably low, There is a big problem that is poor.

On the other hand, in places where water is scarce, salty water is removed from seawater and a large amount of fresh water such as drinking water, industrial water, and agricultural water is produced and used. Such seawater desalination is aimed at obtaining fresh water such as drinking water.

Therefore, the above-described decontamination methods can obtain salt from seawater, but in this process, a large amount of water is evaporated, and in the seawater desalination process, fresh water such as drinking water is obtained, so that salt can not be obtained.

In addition, such a seawater desalination apparatus has a problem in that it has a limitation in the place due to its wide installation area and there is a limit to continuously increase the processing capacity.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made in order to solve the above-mentioned problems, and it is an object of the present invention to provide a method of producing natural salt by introducing seawater or deep seawater from a sea, And to provide a device for producing salt and drinking water.

In order to achieve the above object, the present invention provides an apparatus for producing fresh water and salt by drying seawater, comprising: a rotating shaft installed vertically in a main body and rotated by receiving power from a motor; The hot water supply port is formed on one side and the hot air discharge port is formed on the other side, and a plurality of upper and lower stages are coupled to the rotary shaft in a plurality of stages, A drying plate comprising an impurity removing unit for removing impurities contained in the salt crystals by heating the salt crystals to a high temperature, the drying unit comprising a moisture removing unit for forming salt crystals by evaporating moisture, The method comprises stirring the seawater by rotating the rotating shaft while rotating together with the rotating shaft to induce smooth drying of the seawater supplied on the drying plate, moving the salt crystals formed by evaporating the water contained in the seawater and seawater, And a plurality of vanes are coupled to the plurality of vanes so as to be inclined at predetermined intervals so as to gradually move the salt crystals formed on the veneer to the center or outer edge of the veneer; A steam collecting pipe installed at an upper portion of each of the drying plates and collecting water vapor generated when the seawater is dried on the drying plate; A condenser for condensing and desalting the water vapor collected through the water vapor collecting pipe (50); And a discharge groove formed in a center portion or an outer edge portion of the drying plate so as to allow the seawater and the salt crystals on the respective drying plates to be dropped to the drying plate at the bottom or to be discharged to the outside, And the wings coupled to the end of the scraper are made of a rubber material so as to smoothly move along the inclined surface.
