Abstract

PURPOSE:To produce the subject substance free from impurities such as heavy metal and easily absorbable in human body by placing the upper shell of oyster between three-phase electrodes of an electric furnace, filling the space with activated carbon and applying prescribed voltage to the electrodes to effect electric discharge. CONSTITUTION:The main body 1 of an electric furnace having a bottom wall 1a and a cylindrical wall 1b is provided with three-phase electrodes 2 (an electrode is placed on the bottom wall 1a and the other two are placed on the cylindrical wall 1b in a state opposite to each other in radial direction) and the outer circumference of the main body is covered with refractory brick 3. The upper shell 4 left after removing the meat of raw oyster is used as the sole raw material and placed as it is between the electrodes 2. The space in the furnace is filled with activated carbon 5 and the furnace is electrified to effect the electric discharge for 5-9hr. The content of the furnace is cooled by spending 6-10hr, taken out of the furnace and sieved with a vibration sieve (250 mesh). The ionized upper shell 4 is easily pulverized to fine powder to pass through the sieve and the impurities such as heavy metal are left on the sieve. A high-quality objective material can be produced by using the upper shell having low impurity content keeping the original form of the shell as exclusive raw material.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing ionized calcium by ionizing oyster shells.

[Prior Art] It is already known that calsulaum, which is made from oyster shells, is useful for the human body, and if oyster shells are made into powder, the absorption rate in the body is low. In recent years, it has been found that the higher the ionization concentration of calcium necessary for the human body, the better it is digested and absorbed in the human body's digestive tract. Therefore, various methods of ionizing calsulum have been considered.

For example, as shown in Fig. 2, electrodes a are interposed at regular intervals, an oyster shell is placed between the electrodes 2, and carbon powder C is filled in the gap between the electrode a and the oyster shell. However, there is a method for producing ionized calcium in which oyster shells are ionized by applying a predetermined voltage between two electrodes to cause discharge, and the oyster shells are taken out from between the electrodes and turned into powder.

Further, as shown in FIG. 3, a pair of electrodes a are attached to a predetermined position of a tubular body e, which is formed so as to be heated by disposing a heating body d on its outer periphery.
, a, and continuously feed the oyster shell r, which has been powdered in advance, into the tubular body e at a predetermined speed, heat the heating element d by applying electricity, and apply a voltage to the electrodes a, a. There is a method for producing ionized calcium that ionizes powdered oyster shells by ionizing powdered oyster shells.

[Problem to be solved by the invention] However, in the conventional method for producing ionized calcium shown in Figure 2, an electrode or two electrodes are used, and the oyster shells used are not specified and are used at random. Since I am using
Ionization requires a large amount of power, and ionization is insufficient and uneven. Furthermore, impurities such as heavy metals, which are resistant to and contained in oyster shells, are contained in the powdered ionized calcium. The method for producing ionized calcium shown in Figure 3 requires a heating device to heat the oyster shell powder, and since the electrodes are bipolar, a large amount of power is still required for heating and ionization, and ionization is insufficient. There were some problems such as.

In view of the above-mentioned circumstances, the present invention uses an apparatus that simplifies the process, does not contain impurities such as heavy metals, and is easily soluble in water.
The object of the present invention is to provide a method for producing ionized calcium that can obtain high quality ionized calcium that is easily digested and absorbed in the digestive tract of the human body.

[Means for Solving the Problems] The present invention provides an arrangement in which an oyster shell top cover is placed between three phase electrodes of an electric furnace, activated carbon is filled in the gap between each of the electrodes and the oyster shell, and then the electrodes are filled with activated carbon. The method for producing ionized calcium includes ionizing the oyster shell by applying a predetermined voltage and causing discharge.

[Function] Therefore, in the present invention, only the upper lid, which has a low content of impurities such as heavy metals among oyster shells, is used as a raw material, and the oyster shell is preserved in its original shape.
By placing activated carbon between the phase electrodes and filling the space between the electrodes and the oyster shell as a current medium, and applying a predetermined voltage to the electrodes to cause a discharge, a uniform current passes through the oyster shell and the layered Impurities existing between the layers of eggplant oyster shells can be removed from the layers, and the oyster shells can be ionized to a high concentration, making it possible to produce genuine, high-quality ionized calcium.

[Example] Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, in which a bottom wall surface 1a having a predetermined diameter is shown.
An electric furnace main body 1 having a cylindrical wall surface 1b continuous to the bottom wall surface 1a is provided, and three-phase electrodes 2 are provided on the electric furnace main body 1, one pole is provided on the bottom wall surface la, and the other two The poles are arranged at predetermined locations on the cylindrical wall surface 1b so as to face each other in the radial direction, and the outer periphery of the electric furnace main body 1 is covered with refractory bricks 3.

Next, of the two shells after peeling off the flesh of the raw oyster,
Using only the upper shell 4 as a raw material, the upper shell 4 is placed in its original form between the electrodes 2, and the gap between the upper shell 4 and the electrode 2 is filled with activated carbon 5 as a current medium. A voltage is applied to cause discharge, and electricity is supplied to the top shell 4 through the activated carbon 5 for about 5 to 9 hours.

By applying electricity as described above, the upper lid shell 4 is heated to approximately 800 m
When heated to ~1200°C, impurities present between the layers of the upper shell 4 are removed from the layers, and the shell 4 is ionized to a high concentration.

After cooling the shell 4 for about 6 to 10 hours, it is taken out from the electric furnace main body I and passed through a vibrating sieve (not shown) (equipped with a 250-mesh mesh, drive motor rotation speed 168, stroke 145 mm). The upper lid shell 4, which has been heated and ionized as described above, easily becomes a fine powder.

The pulverized upper shell 4 passes through the mesh, or impurities such as heavy metals remaining on the raw material upper shell 4 remain on the vibrating sieve because they are not pulverized enough to pass through the mesh. In this way, it is possible to obtain pure oyster shell powder free of impurities.

According to the above, the raw material is limited to only the upper cap shell 4 with relatively few impurities among oyster shells, and the oyster upper cap shell 4 is
By placing the phase in the electric furnace main body 1 and applying electricity, the shell 4 can be ionized to a high concentration and impurities can be removed from between the layers of the shell 4. Furthermore, when the ionized upper lid shell 4 is pulverized by passing it through a vibrating sieve. By eliminating impurities, it is possible to obtain pure, high-quality ionized calcium.

In addition, the raw materials are grown in clean seawater and are free of arsenic,
From the shells of live oysters that have not been contaminated with heavy metals or other contaminants, just after being shucked, or from the shells that have been sealed and stored under strict control immediately after being shucked, only the top cap is selected, and its size, shape, etc. It is preferable to use oyster shells that have the following characteristics.

Furthermore, the present invention is not limited only to the above-mentioned embodiments, and the values of the mesh, vibration, stroke, etc. of the sieve can be appropriately selected, and the time of energization in the furnace, the heating temperature of the upper lid shell,
It goes without saying that the cooling time of the upper lid shell after electrical heating can be appropriately selected depending on the actual situation, and that various other changes can be made without departing from the gist of the invention.

[Effects of the Invention] As explained above, the method for producing ions and other calcium of the present invention can produce various excellent effects as described below.

(D) Three-phase electrodes were appropriately arranged in the electric furnace body, and the gap between the oyster shell and the electrodes was filled with activated carbon.
With a simple structure, it is possible to constantly apply a uniform current to the oyster shell, and a high concentration of ions and calcium can be obtained.

(ID) Since the raw material is limited to the upper lid, which has relatively few impurities in the oyster shell, it is possible to obtain high-quality ions and calcium compared to the case where the entire oyster shell is used as the raw material.

■ When raw oyster shells are powdered, impurities are also powdered, making it difficult to remove them. However, by heating and ionizing raw oyster shells, it is easy to remove impurities, as explained in the example. In this case, in combination with the above-mentioned item (II), it is possible to obtain even better quality ions and calcium.
