It is the conceptual diagram which showed the mineral extraction apparatus which concerns on embodiment of this invention. It is the conceptual diagram which showed the modification of the mineral extraction apparatus.

  The mineral extraction method and the mineral extraction apparatus according to the present invention extract a mineral from a mineral to generate a mineral extract. The produced mineral extract can be used in various industrial fields such as agriculture, fishery, and food manufacturing. Naturally, the mineral extract can be used for the production of drinking water, food, and the like, and therefore should be generated on the assumption that it is taken into the human body. In view of this, the mineral extraction method and the mineral extraction apparatus according to the present invention can efficiently extract minerals from minerals without using strong acids that can cause health damage to the human body, as described in the following embodiments. It is a thing.

  As shown in FIG. 1, in the mineral extraction method according to the embodiment of the present invention, a slurry generation step, a heat treatment step, a filtration treatment step, and a sterilization treatment step are executed. Moreover, these processes can be performed with the mineral extraction apparatus shown in FIG. Hereinafter, each step will be specifically described.

<Slurry production process>
In the slurry generation step, water, mineral, and sulfate are mixed to generate a mixed slurry 10A. Specifically, water, a mineral, and a sulfate are put into a stirring tank 1 (see FIG. 2) that is a slurry generating unit. And stirring slurry 10A is produced | generated by stirring these. The generation of the mixed slurry 10A is not limited to the stirring tank 1, and a tank having no stirring function may be used.

  Here, purified water (water containing many hydroxyl groups) is used as water.

  Granite, zeolite ore, bakuhan stone, corroded granite, etc. are used as minerals. These minerals include various minerals, and the mineral to be used can be selected according to the mineral to be extracted. In addition, only one type of mineral may be used for mineral extraction, and a plurality of types of minerals may be used in combination.

The mineral to be used is finely crushed and charged into the stirring tank 1. At this time, the surface area Sf per unit mass of the mineral is preferably 0.2 m 2 or more and 5 m 2 or less. Thereby, the processing speed of mineral extraction can be increased.

  As the sulfate, zinc sulfate, aluminum sulfate, ammonium sulfate, potassium sulfate, calcium sulfate, ferrous sulfate, sodium sulfate, magnesium sulfate and the like are used. Any of these sulfates can be used as a food additive, and has low possibility of causing health damage to the human body and is highly safe. In addition, only 1 type sulfate may be used for mineral extraction, and multiple types of sulfate may be used in combination.

  The sulfate is preferably added so that the weight ratio to the mineral is 0.5 or more and 1 or less. Moreover, it is preferable that water is input in the same weight as the mineral.

<Heat treatment process>
In the heat treatment step, the mixed slurry 10A is heat treated to extract minerals in the mineral. Specifically, the mixing slurry 10A in the stirring tank 1 is heated by heating the stirring tank 1 with a heater 2 (see FIG. 2) which is a heat treatment unit. As the heat treatment conditions at this time, the heat treatment temperature, the heat treatment time, the pressure applied to the mixed slurry 10A, and the like are optimized, whereby the mineral can be efficiently extracted from the mineral. Specifically, it is as follows.

  The mixed slurry 10A is preferably heated to a predetermined temperature Th of 80 ° C. or higher and 160 ° C. or lower. Further, when the mixed slurry 10A is heated, after the temperature T of the mixed slurry 10A reaches the predetermined temperature Th, the temperature T of the mixed slurry 10A is maintained at the predetermined temperature Th for a predetermined period tp of 24 hours to 168 hours. It is preferable.

  In the present embodiment, the stirring tank 1 has a lid 12 that can seal the charging port 11. And the pressure in the stirring tank 1 is raised by heating the stirring tank 1 in a sealed state. At this time, the mixed slurry 10A is preferably pressurized to a predetermined pressure Ph of 1 Pa to 15 Pa. In addition, the pressure in the stirring tank 1 may be increased using a pressurizing device such as a pressurizing pump.

  Thus, by optimizing the heat treatment conditions, the sulfate is easily decomposed into sulfate ions (anions) and inorganic ions (cations). Therefore, many sulfate ions separated from the sulfate are combined with minerals (inorganic matter) in the mineral, and as a result, many minerals are extracted from the mineral. That is, the processing speed of mineral extraction can be increased. Therefore, the running cost required for mineral extraction is reduced.

<Filtering process>
In the filtration process, the mixed slurry 10A after the heat treatment process is filtered to generate a mineral extract 10B. Specifically, minerals are mainly removed from the mixed slurry 10A by the filtration device 3 (see FIG. 2) which is a filtration processing unit. The filtration device 3 is, for example, a multistage filter, and removes almost all minerals contained in the mixed slurry 10A from particles having a large diameter to particles having a small diameter. That is, the produced mineral extract 10B is filtered to a level at which it can be used for drinking water, food, and the like after passing through the sterilization treatment step.

  In the present embodiment, the filtration device 3 includes a coarse separator 30 that removes a large diameter of minerals, a first filtration filter 31 that removes a small diameter of minerals, and a second filter. And a filtration filter 32. As the first filtration filter 31 and the second filtration filter 32, for example, a 0.2 μm ceramic filter is used.

  Moreover, in this embodiment, the mineral extract 10B produced | generated through the filtration process is stored in the stirring tank 4 different from the stirring tank 1. FIG.

<Disinfection treatment process>
In the sterilization treatment process, the produced mineral extract 10B is sterilized. Specifically, viruses, fungi (bacteria, mold, etc.) are removed from the mineral extract 10B by the catalyst filter 5 (see FIG. 2) which is a sterilization processing unit. Here, a silver ion exchange zeolite having a high sterilizing power is used for the catalyst filter 5. By bringing the mineral extract 10B into contact with the silver ion-exchanged zeolite, it becomes possible to efficiently remove viruses and fungi from the mineral extract 10B.

  In the present embodiment, as shown in FIG. 2, a circulation path 40 is provided in which the mineral extract 10 </ b> B in the stirring tank 4 is passed through the catalyst filter 5 and returned to the stirring tank 4 again. Then, the mineral extract 10B is repeatedly passed through the catalyst filter 5 by circulating the mineral extract 10B along the circulation path 40. Thereby, almost all viruses and fungi contained in the mineral extract 10B are removed. That is, the mineral extract 10B after the sterilization treatment is repeatedly sterilized to a level where it can be used for drinking water or food.

  In addition to the catalyst filter 5, the ultraviolet irradiation unit 6 (see FIG. 2) may be used for the sterilization process. In addition, only one of the catalyst filter 5 and the ultraviolet irradiation unit 6 may be used for the sterilization treatment.

  As a modification, as shown in FIG. 3, at least a part of the filtration device 3 (here, the first filtration filter 31 and the second filtration filter 32) is provided in the circulation path 40 together with the catalyst filter 5 and the ultraviolet irradiation unit 6. May be. Thereby, it becomes possible to perform a filtration process and a disinfection process in parallel.

  Since the mineral extract 10B produced | generated through the various processes mentioned above was produced | generated using a sulfate, it does not contain a strong acid or it is a very small amount even if it contains a strong acid. Therefore, it is possible to obtain a highly safe mineral extract 10B with low possibility of causing health damage to the human body without post-treatment such as neutralization.

  Tables 1 and 2 below use the granite quarried in the Abukuma Mountains of Fukushima Prefecture as minerals, ammonium sulfate / aluminum and magnesium sulfate as sulfates, and alkaline water (reduced water) as water. The analysis result of the mineral extract 10B produced | generated through the process is shown. Here, Tables 1 and 2 show the results obtained by analyzing the diluted solutions obtained by diluting the mineral extract 10B with water to 25% and 50%, respectively. According to these analysis results, it can be seen that the mineral contains a lot of potassium, calcium, iron, and magnesium that are nutrients for the human body. On the other hand, it does not contain sulfuric acid, which can be harmful to human health.

  The generated mineral extract 10B can be used in various industrial fields such as agriculture and fishery, as well as the production of drinking water and food. Further, the mineral extract 10B may be used for sewage treatment (purification), washing, and the like. In the use of the mineral extract 10B, when the sterilization process for the mineral extract 10B is not necessary, the above-described sterilization process may be omitted.

  Furthermore, according to the mineral extraction method and the mineral extraction apparatus described above, since it is not necessary to use a strong acid, the safety of the operation required for mineral extraction is enhanced. Furthermore, management required for mineral extraction becomes easy.

  When drinking water is manufactured using the mineral extract 10B, the mineral concentration of the mineral extract 10B is adjusted by being hydrated. Further, the concentration-adjusted water whose mineral concentration has been adjusted is sealed in a container such as a plastic bottle through heat treatment and filtration treatment.

  Further, the mineral extract 10B is used for washing vegetables, fruits and the like, so that the vegetables can be used as compared with the case of washing with water that has not been treated (hereinafter referred to as “untreated water”). Pesticides adhering to fruits and fruits can be washed off efficiently.

  Table 3 below analyzes the amount of pesticide (teflubenzuron) remaining in the washed eggplant when the eggplant is washed with the mineral extract 10B and when the eggplant is washed with untreated water. Shows the results obtained. According to this analysis result, it can be seen that by using the mineral extract 10B for washing, the pesticide can be washed off efficiently.

  The above description of the embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Further, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
