Description

METHOD FOR MANUFACTURING SOLUBLE MINERAL POWDER [0002]

The present invention relates to a method for producing a water-soluble mineral powder, and more particularly, to a method for producing a water-soluble mineral powder produced by a physical or electrical method without using any chemical or artificial substance will be.

In general, minerals such as potassium, magnesium, and sodium, which are beneficial to the human body, include calcium, magnesium, magnesium and sodium, while calcium relaxes and shrinks the muscles and excites the nerves while potassium, magnesium and sodium relax the muscles and stabilize the nerves , The proper balance of these minerals in the body is needed for the normal functioning of muscles and nerves.

Calcium is the most abundant mineral in the body, and most of the calcium in the body, which accounts for 1.5% ~ 2.2% of body weight, is present in the skeleton. It is the most important role in

In addition, calcium is present in the blood as a phosphorylated apatite, 45% of which is bound to proteins such as albumin, 10% is present as phosphate and citrate, and the remaining 45% is present as free calcium, It has a lot of influence.

Potassium acts in the body to form the skeleton and teeth that maintain the structure of the human body, solidify the blood, maintain the acid and alkali balance of the body fluids, and maintain muscle and nervous system safety in terms of muscle spasms, Relaxation, heartbeat, excitement of the nerves, and activation of the stimulating transporter. It also affects the secretion of hormones produced by the endocrine organs and regulates cell membrane function and mass transfer.

Meanwhile, conventionally, limestone was calcined at a temperature of 1200 to 1500 ° C by a method of producing minerals with limestone, and the limestone was crushed by a crusher to produce powders to produce minerals (mainly calcium).

However, minerals produced by calcination at temperatures above 1,000 ° C are incompetent minerals that do not fulfill their mission.

Further, the calcium oxide obtained by the above-mentioned method does not become water-soluble calcium because it absorbs moisture and carbon dioxide gas in the atmosphere and changes into calcium hydroxide (calcium hydroxide) or calcium carbonate.

Furthermore, when consumed in large amounts, there is a risk of incomplete digestion and gallstones, so that it is hardly used for edible purposes, and is used for industrial use, fertilizer or feed additive.
