SOLUTION: Natural rocks containing minerals such as granite porphyry, rock of Mt. Iwo and tourmaline is pulverized and classified to obtain a mineral- contg. natural rack powder of a specified grain size. Then the mineral-contg. natural rock powder by about 55wt.%, at least one kind selected from wood powder, chaff, rice bran, soy bean bran and carbon (bamboo of charcoal) powder, by about 2wt.%, a silica powder by about 15wt.% and the balance water are mixed and stirred to obtain a compsn. The obtd. compsn. is supplied in a die and formed under pressure into a specified shape. The formed body is dried in air and calcined at about 800 deg.C to obtain a mineral-eluting porous calcined body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a calcined product having a number of voids, which is a powder for facilitating the elution of a mineral active ingredient of a mineral-containing natural stone and efficiently performing it without damaging the ingredient.

[0002]

2. Description of the Related Art Generally, in order to utilize minerals containing mineral-containing natural stones, a method of eluting the minerals by immersing the powder as it is or molding it into a predetermined shape by pressing etc. in a solvent is adopted. In the method, elution requires a long time and the elution amount is small.

Therefore, in order to increase the elution amount of minerals in the solvent, a method has been adopted in which mineral-containing natural stones are finely divided or put in a large amount in the solvent. However, minerals which are active ingredients are efficiently used. I can't.

Therefore, in order to increase the amount of mineral elution, it is necessary to increase the amount of the mineral-containing natural stone to be immersed or shorten the exchange cycle of the mineral-containing natural stone. It becomes complicated.

[0005]

In order to solve the above-mentioned drawbacks, a molded body having a shape capable of efficiently eluting minerals by increasing the contact area between the mineral-containing natural stone and the solvent is indispensable. The present invention is provided to solve such a problem.

[0006]

This porous fired body is prepared by pulverizing mineral-containing natural stone, classifying it, and producing powder having a predetermined particle size. As the mineral-containing natural stone, any one containing a large amount of minerals such as barley stone, medio stone, tourmaline can be widely used.

Mineral-containing natural stone powder, wood powder, rice husk,
1 selected from rice bran, okara powder and carbon (bamboo charcoal, charcoal) powder
One or two or more kinds of powders, a composition consisting of silicon dioxide and water is thoroughly mixed, the composition is put into a mold or a resin mold, and the mixture is pressurized, dried in the air after molding into a predetermined shape,
A mineral-eluting porous fired body can be obtained by firing.

When a large amount of water is used to elute minerals, it can be obtained by producing a unit containing a plurality of mineral-eluting porous fired bodies and passing the water through.

[0009]

[Function] A composition comprising one or more powders selected from wood powder, rice husk, rice bran, okara powder, carbon (bamboo charcoal, charcoal) powder, silicon dioxide powder, and water is added to mineral-containing natural stone powder. By molding into a predetermined shape and baking at 800 ° C or higher, the wood powder, rice husk, rice bran, okara powder, and carbon (bamboo charcoal, charcoal) powder in the molded body are lost, effectively creating a myriad of small voids. It is formed. Therefore, the contact area between the molded body of mineral-containing natural stone powder that has become porous and the solvent is increased, and the capillary action of the voids promotes the penetration of the solvent, which shortens the elution time of the mineral in the solvent. In addition, since the water retention rate is extremely large at 40 to 50% by weight, the amount of minerals eluted is also increased.

BEST MODE FOR CARRYING OUT THE INVENTION A specific example of a method for producing a fired body of the present invention will be described below, and a comparative example will be shown below in order to further clarify the effect of the fired body of the present invention.

Examples 55% by weight of barley stone powder having a particle size of 1 to 5 μm, a particle size of 30 to 100 μm and 10% by weight of wood powder, a particle size of 15 to 50 μm
220 g of a composition containing 2% by weight of wood powder, 15% by weight of silicon dioxide powder having a particle size of 1 to 50 μm, and the balance being water is stirred and mixed, and the composition is put into a mold and pressed to form a disk shape of 80φ × 20 mm. Molded. After being dried in the air, it was fired at 800 ° C., and after being cooled in the furnace, a mineral-eluting porous fired body could be obtained.
One piece (150 g) of this mineral-eluting porous fired body was put into 2 liters of distilled water, and 100 ml of immersion water after stirring for 2 hours with a stirrer
Table 1 shows the results of water quality inspection. Mineral elution By immersing the porous fired body in distilled water, elution of minerals such as sodium, magnesium and calcium was confirmed.

<Comparative Example> Table 1 shows the results of the water quality test in which a fired body was prepared by the same method as in Example 1 except that wood powder was not added and similarly immersed, in comparison with the example.

[Table 1]

Furthermore, one mineral-eluting porous fired body was placed in 2 liters of tap water (Tama-shi, Tokyo) and continuously stirred with a stirrer, and immersion water 100 after 10 minutes, 1 hour and 3 hours had passed.
ml was taken. Further, tap water was similarly continuously stirred, water was collected at the start, 10 minutes, 1 hour and 3 hours, and residual chlorine of each was measured by the ortho-tolidine method. Table 2 shows the results. In the immersion water containing the mineral-eluting porous fired body, residual chlorine decreased 10 minutes after the start of immersion, and about 50% decrease 1 hour later.

[Table 2]

[0013]

As described above, according to the present invention, by immersing a calcined body of a mineral-containing natural stone powder that has become porous in tap water, the mineral is eluted from the calcined body and the mineral is dissolved in tap water. It has the effect of removing the residual chlorine, so that delicious water can be obtained.
