Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely one preferred embodiment of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It is to be understood that equivalents and modifications are possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart showing a method of preparing an aqueous calcium ion solution according to an embodiment of the present invention.

Remove the foreign matter and impurities through the washing of shellfish in step S10 and then dried. Shell (Shell, 貝殼) refers to the inorganic secretion formation to protect the molluscs in mollusks, where shells may be used such as oyster shells, shell shells.

Subsequently, the dried shellfish in step S20 is heated and calcined to remove organic matter and residual toxicity contained in the dried shellfish, thereby preparing calcium oxide.

In this case, calcium oxide may be prepared by heating and calcining dried shellfish at 1300 ° C. to 2000 ° C. for 1 to 3 hours.

In this case, calcium oxide may be prepared by heating and firing the dried shellfish at an initial temperature of 1300 ° C. and gradually raising the temperature to a final temperature of 2000 ° C.

Here, calcium carbonate (CaCO ₃ ), which is a constituent of the shellfish, is calcined and converted into a solid calcium oxide (CaO).

Subsequently, the calcium oxide powder prepared in step S30 is wet ball milled to prepare a calcium oxide powder.

In this case, the particle diameter of the pulverized calcium oxide powder may be 10 μm or less. If the particle diameter of the calcium oxide powder is more than 10㎛ there is a problem that does not mix well when preparing a calcium oxide solution by mixing with water, but calcium oxide powder having a particle diameter of less than 10㎛ is well mixed in water.

Subsequently, the calcium oxide powder and water are mixed and stirred in step S40 to prepare a calcium oxide solution. The calcium oxide solution prepared here is strongly alkaline.

In this case, the mixing ratio of water and calcium oxide powder may be 0.1 to 2 parts by weight based on 100 parts by weight of water and calcium oxide powder. Here, if the ratio of calcium oxide powder exceeds 2 parts by weight, it may not be mixed sufficiently with water. If the ratio of calcium oxide powder is less than 0.1 parts by weight, the prepared aqueous calcium ion solution may not supply enough calcium in the body, but it may be sufficiently filled with water when 0.1 to 2 parts by weight. It mixes well and exhibits the effect of supplying sufficient calcium in the body as an aqueous solution of calcium ionization.

At this time, the calcium oxide powder and water may be mixed and stirred for 3 to 5 hours to prepare a calcium oxide solution. The calcium oxide powder is evenly mixed with water by stirring for 3 to 5 hours.

Subsequently, saturated steam is supplied to a container including the calcium oxide solution prepared in S50 to induce an ionic reaction by generating static electricity in the container, thereby preparing an aqueous calcium ion solution.

First of all, saturated steam generated in a boiler generates some condensation due to the temperature drop in the vessel, which results in the formation of droplets. The generated droplets collide or rub against each other, thereby generating static electricity. In addition, the supplied air is expelled by the supplied saturated steam, and saturated steam also penetrates into the calcium oxide solution. The static electricity accumulated in the droplets reaches the container either directly or through calcium oxide solution.

The portion where the static electricity flows in the calcium oxide solution is locally heated to rise in temperature and ion structure, but the current is not continuously flowing and the amount of power is small, so the temperature rise is small. In addition, since the average temperature in the container does not rise above the temperature of the saturated steam supplied, harmful components hardly occur.

In addition, since saturated steam is filled in the container, even if sparks are generated by the flow of static electricity, it is prevented from being flammed by flammable gas or the like.

Thus, by using the heat, pressure and static electricity of saturated steam, a stable water-soluble ionization calciumation action occurs.

Meanwhile, since the vessel and the stirring means are made of a chargeable material, ionization may be promoted according to the following mechanism. When the vessel and the stirring means are charged and provided in an insulated state with respect to the base, the calcium oxide solution, the vessel and the stirring means have positive or negative charges (electrostatic) due to friction with the calcium oxide solution. Accumulates. On the other hand, the saturated steam heated and pressurized is supplied in the container, and since this saturated vapor penetrates into the inside of the calcium oxide solution, the electrical resistance inside the calcium oxide solution decreases, so that electricity easily flows.

Here, the charging property means that the electrical resistance is large and that the added calcium oxide solution can be positively or negatively charged. The charging may be performed either positively or negatively.

For example, when a certain amount of negative charge is accumulated in the calcium oxide solution when positive charge is accumulated in the vessel and the stirring means, the charge flows through the inside of the calcium oxide solution and into the vessel and the stirring means. Since the calcium oxide solution is agitated, the amount of charge collection varies with each part, and the path and time through which the charge flows also differ. In addition, since saturated steam is filled in the container, the electrical resistance is not too high or the static electricity is not collected too much. Therefore, the static electricity is discharged little by little, and instantaneously generates heat in the discharge path during discharge, while the calcium oxide solution is converted into a stable aqueous solution of calcium ionization. However, since discharge is not carried out continuously, it does not become a high temperature, the entire temperature in the container does not increase significantly at the set temperature by heating steam, and water suppresses the generation of harmful components.

In this case, the pressure of the saturated steam supplied to the container including the calcium oxide aqueous solution may be 1.4 to 5 MPa.

And step S50 is the step of injecting calcium oxide solution into the container, the static electricity generated by the water droplets generated while supplying saturated steam at a temperature of less than 300 ℃ and a pressure of 1.4 to 5 MPa to the container, the pressure inside the container Inducing the ionic reaction by stirring the inside of the vessel while maintaining the constant, discharging the saturated steam in the vessel to the first decompression tank to achieve a pressure equilibrium between the inside of the vessel and the inside of the first decompression tank, closing the first decompression tank Thereafter, the method may include discharging the saturated steam in the vessel to a second decompression tank having a volume larger than that of the first decompression tank, and obtaining an aqueous calcium ion solution in the first decompression tank and the second decompression tank. .

Subsequently, in step S60, the hydrogen ion concentration is maintained at pH 12 to pH 13 by adding soft water or pure water to the aqueous calcium ion solution.

Herein, soft water treated water refers to water whose hardness is adjusted to less than 0 to 60 mg / L, and pure water treated water refers to water from which impurities including hardness components are removed.

On the other hand, the aqueous solution of calcium ion prepared according to the embodiment of the present invention can be used as additives of fish feed, additives of livestock feed, calcium ionized drinks and calcium fortification of plants, but is not limited thereto.

Table 1 shows the hydrogen ion concentration according to the content ratio of the calcium oxide powder of the aqueous solution of calcium ion prepared according to the embodiment of the present invention.

As the calcium oxide powder dissolved in 10 ml of water increases from 0.01 g to 0.05 g, the pH value gradually increases from 12.340 to 12.412. The calcium oxide powder becomes more alkaline as it is dissolved in water.

Table 2 shows the results of the bactericidal, pH change and dissolution rate of the aqueous calcium ion solution prepared according to the embodiment of the present invention.

Calcium ionized aqueous solution prepared according to an embodiment of the present invention is easily absorbed into the cell body without the aid of absorption promoters such as vitamin D ₃ to maximize the efficacy of the calcium ion when absorbed in the cell body. That is, it is possible to directly ingest and absorb, and to add a predetermined amount to fish and livestock feed as the main ingredient or auxiliary material, so that the water-soluble ionized calcium contained in the feed suppresses the deterioration of the feed and the generation of bacteria, thereby increasing the shelf life. . This minimizes the loss of nutrients and adds water-soluble ionized calcium to make calcium ionization easier to eat, and increases the body's absorption of calcium to make up for the lack of calcium in the feed, thereby increasing the metabolism of fish and plants and animals.
