Description

Manufacturing method of pure mineral salt

The present invention relates to a method for preparing pure mineral-containing salt, and more particularly, to remove impurities such as heavy metals contained in sun salt and maximize mineral content, thereby providing a method for producing pure salt that is beneficial to the human body.

Processing salts include recontaminated salts, baked salts, flavored salts, washed salts, by-product salts, refined salts, and the like.

Firstly, re-decontamination is also called white salt and flower salt, and it is recrystallized by boiling 100-200 ° C in a flat pot (bottomed flat pot) by dissolving imported salt and domestic sun salt in water at 9: 1. It is a low salinity salt of 88-90%, and 10-150,000 tons are produced annually at about 30 factories in Korea, but it is not enough to remove heavy metals and impurities in cheap imported salts.

Baked salt is organic salt and arsenic is removed by baking natural salt in 400-450 ℃ for 1-4 hours in one stage in ceramic reactor, and arsenic, oxide and cadmium are removed in 30 minutes-4 hours at 550-600 ℃ in two stages. The last step is to bake 30 minutes-4 hours at 700-800 ℃ to remove oxides such as lead, refractory organics, calcium and magnesium, but if the temperature is not adjusted step by step or the temperature is not maintained, harmful substances are not removed. This method of removing harmful substances by simple heating is not suitable as a salt manufacturing method for salt extraction, which is beneficial to the human body.

Flavored salts include salt salts coated with raw salt (mechanical salt) and sodium glutamate, salt and bamboo salt baked three times at 1,300 ° C or higher. Especially, bamboo salt is packed in bamboo, and the bamboo inlet is sealed with mud. In the kiln, bake at 1000-1300 ℃, repeat the same way, roast eight times, and in the ninth, sprinkle pine powder on wood fire and heat 1300-1700 ℃ to heat nucleus in natural salt. It will be changed to alkaline good for the body. Because of its high price, it is sold in tofu, cosmetics, toothpaste, pharmaceuticals, confectionery, spices, etc., but high-temperature simple processing alone does not help to remove harmful substances such as heavy metals. It is in a state that cannot be activated due to the difficulty of the supplier.

Washing salt is crushed, washed, dehydrated, dried and packaged to reduce insoluble matter 0.02% magnesium chloride and sodium sulfate to within 0.05%. Crystallized grains are large and hard to process seafood such as seaweed, dyes and pigments. It is mainly used for manufacturing, feed, and leather, but it is not suitable for safe use such as spraying potassium herocyanide, which is prohibited to add food to prevent salt hardening during grinding process in some processed salt factories.

By-product salts are also called recovery salts and contain heavy metals and are not allowed to be used in the salt control legislation for food use. Polyvinyl chloride (PVC) is used in incinerators of caustic soda and soda ash. When burning, a lot of chloride gas (HC1) comes out, and sodium chloride is produced by spraying caustic soda (Naoh) to prevent it.

Refined salt is a recrystallization of household salts to increase the purity of sodium chloride. Processed salt is processed by adding spices or chemical seasonings to refined salt. In refined salt, impurities are removed and sold by heating such as bamboo salt, but the conventional method is to obtain pure salt by removing impurities such as heavy metal by simple repeated heating for 1-3 times. It is a situation that does not completely remove the impurities of the, and the situation is just a composition of the refined salt component level.

In other processed salts, iodine added salts have a significant effect on the prevention of thyroidism in order to prevent thyroid disorders. In addition, salts containing fluorine, zinc, etc. may be sold. In addition, flame, wood salt, beard, gold salt, There are methods for producing functional processed salts such as earth salts, gilt salts, poison salts, mugwort flavors, basophils, yeast salts, and high salts.

Accordingly, in the present invention, as a method for preparing pure salt in which a special impurity removal process and a large amount of minerals are added to the conventional general salt processing method as described above, it is possible to obtain pure salt rich in minerals beneficial to the human body. It is completed as.
