Description

TECHNICAL FIELD The present invention relates to a technique for extracting minerals from minerals to produce mineral water.

Sodium, magnesium, phosphorus, sulfur, chlorine, potassium, calcium, chromium, manganese, iron, cobalt, copper, zinc, selenium, molybdenum, iodine, and the like. These minerals are necessary for the formation of tissues (such as bones) in the body and the adjustment of human body functions.

Foods such as seafood and seaweeds contain many minerals necessary for the human body, and are taken into the body by ingesting these foods. On the other hand, many minerals cannot be stored in the body. Therefore, minerals need to be ingested through daily meals or the like.

However, even if minerals are ingested through daily meals, etc., calcium and iron are likely to be deficient. A lack of calcium can be the cause of conditions such as osteoporosis. Insufficient iron can also cause abnormalities such as anemia.

Mineral drinking water is attracting attention as a means of efficiently ingesting minerals that tend to be deficient.

Conventionally, there has been a technique of eluting minerals from minerals using a strong acid such as sulfuric acid or hydrochloric acid (for example, Patent Document 1). When a mineral extract obtained by such a technique is to be used in mineral drinking water, it has been necessary to subject the extract to removal of strong acid (neutralization treatment).

Japanese Patent Application Laid-Open No. 2010-5532 Japanese Patent Application No. 2016-133815

As is well known, strong acids are substances that can pose health hazards to the human body. However, it has been difficult to completely remove the strong acid from the mineral extract.

Therefore, the present inventor has proposed a technique for efficiently extracting minerals from minerals without using strong acid (see Patent Document 2). In the process of further developing such technology, the inventor of the present invention discovered that during the process of producing mineral water by subjecting the mineral extract to water treatment, a small amount of fungi floating in the air ( Yeast, etc.), algae, or a small amount of fungi adhering to a container such as a PET bottle containing mineral water may be mixed with mineral water, and the mixed small amount of fungi or algae may grow in mineral water. rice field.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to prevent the proliferation of fungi, algae, and the like in mineral water produced by subjecting a mineral extract to water treatment.

A mineral water manufacturing apparatus according to the present invention includes a hydrating unit and a degassing unit. The water treatment unit applies water treatment to the mineral extract to generate a diluent (mineral water). The deaeration unit deaerates at least one of the diluent and the water used for the hydration treatment.

It is preferable that the manufacturing apparatus further includes a mineral extracting section that generates a mineral extract, and the mineral extracting section includes a slurry generating section, a heat treatment section, and a filtration processing section. The slurry generator generates mixed slurry in which water, minerals, and sulfate are mixed. The heat treatment section applies heat treatment to the mixed slurry in the slurry generation section to extract minerals from the minerals. After the processing in the heat treatment section, the filtration processing section filters the mixed slurry to generate a mineral extract.

In the manufacturing apparatus described above, it is preferable that the mineral extraction section further includes a sterilization processing section that performs sterilization processing on the mineral extract.

A method for producing mineral water related to the present invention has a hydrating process and a degassing process. In the first manufacturing method, in the hydration treatment step, the mineral extract is subjected to a hydration treatment to generate a diluent (mineral water). After that, in the degassing process, the diluent is degassed. According to this manufacturing method, the concentration of oxygen, nitrogen, and the like in the diluent can be reduced by removing dissolved gases (gases such as oxygen and nitrogen) from the diluent by degassing. Therefore, even if the diluent contains a small amount of fungi or algae, it is not possible to obtain the oxygen, nitrogen, etc. necessary for growth, and as a result, the growth of fungi and algae in mineral water is suppressed. can do.

In the second production method, in the degassing treatment step, degassed water is generated by subjecting the water used for the hydration treatment to degassing treatment. Thereafter, degassed water is added to the mineral extract in the hydrating step. According to this production method, dissolved gases (gases such as oxygen and nitrogen) are removed from the water for hydration treatment by degassing, so that the concentration of oxygen, nitrogen, and the like contained in the water can be reduced. Therefore, by applying hydration treatment to the mineral extract using the water (degassed water), the concentration of oxygen, nitrogen, etc. in the diluent (mineral water) can be reduced. Therefore, even if the diluent contains a small amount of fungi or algae, it is not possible to obtain the oxygen, nitrogen, etc. necessary for growth, and as a result, the growth of fungi and algae in mineral water is suppressed. can do.

Preferably, the production method further includes a mineral extraction step for producing a mineral extract, and the mineral extraction step includes a slurry production step, a heat treatment step, and a filtration treatment step. In the slurry production step, water, minerals, and sulfate are mixed to produce a mixed slurry. In the heat treatment step, the mixed slurry is heat treated to extract minerals from the minerals. After the heat treatment step, in the filtration treatment step, the mixed slurry is subjected to filtration treatment to produce a mineral extract.

According to the production method described above, since the mineral extract is produced using sulfate, the produced mineral extract contains no strong acid, or contains a very small amount of strong acid. Therefore, it is possible to obtain a highly safe mineral extract without post-treatment such as neutralization.

In the above production method, it is preferable to use, as the sulfate, at least one selected from the group consisting of zinc sulfate, aluminum sulfate, ammonium sulfate, potassium sulfate, calcium sulfate, ferrous sulfate, sodium sulfate, and magnesium sulfate. . All of these sulfates can be used as food additives, and are highly safe with a low possibility of harming human health.

In the production method described above, the mineral extraction step preferably further includes a sterilization treatment step of subjecting the mineral extract to sterilization treatment. In the sterilization treatment step, it is preferable to bring the mineral extract into contact with silver ion-exchanged zeolite. This allows the mineral extract to be used in drinking water, food, and the like.

[1] First Embodiment FIG. 1 is a flow chart showing a method for producing mineral water according to the first embodiment. FIG. 2 is a conceptual diagram showing the mineral water manufacturing apparatus according to the first embodiment. As shown in FIG. 1, in the production method of the present embodiment, a mineral extraction process, a hydration process, and a degassing process are performed. These steps can be executed respectively by the mineral extraction unit 101, hydration treatment unit 102, and degassing treatment unit 103 provided in the manufacturing apparatus (see FIG. 2). Each step will be specifically described below.

[1-1] Mineral extraction step In the mineral extraction step, minerals are extracted from minerals to produce a mineral extract. The produced mineral extract can be used in various industrial fields such as agriculture, fisheries and food manufacturing. Naturally, mineral extracts can be used for the production of drinking water, food, and the like, so they should be produced on the assumption that they will be taken into the human body. In view of this, the mineral extraction process described below makes it possible to efficiently extract minerals from minerals without using strong acids that can harm human health.

FIG. 3 is a flow chart showing the mineral extraction process. 4 is a conceptual diagram showing the mineral extractor 101. As shown in FIG. As shown in FIG. 3, the mineral extraction process includes a slurry generation process, a heat treatment process, a filtration process, and a sterilization process. These steps can be executed in the mineral extraction section 101 . In the present embodiment, the mineral extraction unit 101 includes a stirring tank 1 that is a slurry generation unit, a heater 2 that is a heat treatment unit, a filtering device 3 that is a filtration processing unit, a catalyst filter 5 that is a sterilization processing unit, (see FIG. 4).

<Slurry generation process>
In the slurry generating step, water, minerals, and sulfate are mixed to generate a mixed slurry 10A. Specifically, water, minerals, and sulfate are put into a stirring tank 1 (see FIG. 4), which is a slurry generator. By stirring these, mixed slurry 10A is generated. In addition, the mixed slurry 10A is not limited to the stirring tank 1, and a tank without a stirring function may be used.

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

As minerals, granite, zeolite ore, barley stone, eroded granite, etc. are used. These minerals contain various minerals, and you can select the minerals to use according to the minerals you want to extract. For mineral extraction, only one type of mineral may be used, or multiple types of minerals may be used in combination.

The minerals to be used are crushed finely and put into the stirring tank 1. - 特許庁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 sulfates, zinc sulfate, aluminum sulfate, ammonium sulfate, potassium sulfate, calcium sulfate, ferrous sulfate, sodium sulfate, magnesium sulfate and the like are used. All of these sulfates can be used as food additives, and are highly safe with a low possibility of harming human health. For mineral extraction, only one type of sulfate may be used, or a combination of multiple types of sulfates may be used.

It is preferable to add the sulfate so that the weight ratio of the sulfate to the mineral is 0.5 or more and 1 or less. Also, the water is preferably added in the same weight as the minerals.

<Heat treatment process>
In the heat treatment step, the mixed slurry 10A is heat treated to extract minerals from the minerals. Specifically, the mixed slurry 10A in the stirring tank 1 is heated by heating the stirring tank 1 with a heater 2 (see FIG. 4) which is a heat treatment section. By optimizing the heat treatment temperature, the heat treatment time, the pressure applied to the mixed slurry 10A, and the like as heat treatment conditions at this time, it is possible to efficiently extract the minerals from the minerals. 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. Furthermore, during the heating of the mixed slurry 10A, 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 or more and 168 hours or less. is preferred.

In this embodiment, the stirring tank 1 has a lid 12 capable of sealing the inlet 11 . Then, the pressure in the stirring tank 1 is increased 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 or more and 15 Pa or less. The pressure in the stirring tank 1 may be increased using a pressurizing device such as a pressurizing pump.

By optimizing the heat treatment conditions in this manner, the sulfate is easily decomposed into sulfate ions (anions) and inorganic ions (cations). Therefore, many sulfate ions separated from the sulfate bond with minerals (inorganic substances) 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.

<Filtration 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 a filtering device 3 (see FIG. 4), which is a filtering processing unit. The filtering device 3 is, for example, a multi-stage filter, and removes almost all minerals contained in the mixed slurry 10A, from large-diameter particles to small-diameter fine particles. At this time, the mineral extract 10B that is produced is filtered to a level at which it can be used for drinking water, food, and the like through the sterilization process.

In this embodiment, the filtration device 3 includes a coarse separator 30 for removing large-diameter minerals, and a first filter 31 and a second filter 31 for stepwise removal of small-diameter minerals. Filtration filter 32 is included. A ceramic filter of 0.2 μm, for example, is used for the first filter 31 and the second filter 32 .

Further, in this embodiment, the mineral extract 10B produced through the filtration process is stored in a stirring tank 4 separate from the stirring tank 1. As shown in FIG.

<Sterilization process>
In the sterilization treatment step, the generated mineral extract 10B is subjected to sterilization treatment. Specifically, the catalyst filter 5 (see FIG. 4), which is a sterilization processing unit, removes viruses, microbes (bacteria, mold, etc.) from the mineral extract 10B. Here, for the catalyst filter 5, silver ion-exchanged zeolite having high sterilizing power is used. By bringing the mineral extract 10B into contact with the silver ion-exchanged zeolite, it becomes possible to efficiently remove viruses, bacteria, and the like from the mineral extract 10B.

In this embodiment, as shown in FIG. 4, a circulation path 40 is provided for passing the mineral extract 10B in the stirring tank 4 through the catalyst filter 5 and returning it to the stirring tank 4 again. By circulating the mineral extract 10B along the circulation path 40, the mineral extract 10B is repeatedly passed through the catalyst filter 5. As a result, almost all viruses, bacteria, etc. contained in the mineral extract 10B are removed. That is, the mineral extract 10B after the sterilization process is repeatedly sterilized to a level at which it can be used for drinking water, food, and the like.

In addition to the catalyst filter 5, the ultraviolet irradiation unit 6 (see FIG. 4) may be used for the sterilization treatment. Further, only one of the catalyst filter 5 and the ultraviolet irradiation section 6 may be used for the sterilization treatment.

FIG. 5 is a conceptual diagram showing a modification of the mineral extractor 101. As shown in FIG. As shown in FIG. 5, at least part of the filtration device 3 (here, the first filtration filter 31 and the second filtration filter 32) may be provided in the circulation path 40 together with the catalyst filter 5 and the ultraviolet irradiation section 6. good. This makes it possible to perform the filtration process and the sterilization process in parallel.

The mineral extract 10B produced through the various steps described above contains no strong acid, or contains a very small amount of strong acid, since it is produced using sulfate. Therefore, it is possible to obtain the highly safe mineral extract 10B that is less likely to cause health damage to the human body without post-treatment such as neutralization.

Tables 1 and 2 below use granite quarried in the Abukuma Mountains in Fukushima Prefecture as minerals, ammonium sulfate, aluminum sulfate, and magnesium sulfate as sulfates, and alkaline water (reduced water) as water, respectively. The analysis result of the mineral extract 10B produced|generated through the process is shown. Here, Tables 1 and 2 are results obtained by analyzing 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 as minerals, potassium, calcium, iron, and magnesium, which are nutrients for the human body, are contained in large amounts. On the other hand, it does not contain sulfuric acid, which can pose a health hazard to the human body.

The mineral extract 10B thus produced can be used not only in the production of drinking water and food, but also in various industrial fields such as agriculture and fisheries. Also, the mineral extract 10B may be used for sewage treatment (purification), cleaning, and the like. When the mineral extract 10B is not required to be sterilized due to the use of the mineral extract 10B, the aforementioned sterilization process may be omitted.

Furthermore, according to the mineral extraction process described above, since it is not necessary to use a strong acid, the safety of the operation required for mineral extraction is enhanced. Furthermore, the management required for mineral extraction is facilitated.

In addition, the mineral extract 10B is used for washing vegetables, fruits, etc., so that compared to washing with water that has not been treated in any way (hereinafter referred to as "untreated water"), the amount of water that can be applied to the vegetables is reduced. It is possible to efficiently wash off pesticides adhering to fruits, etc.

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

[1-2] Hydration Treatment Step In the hydration treatment step, the mineral extract 10B is subjected to a hydration treatment to generate a diluent 10C (mineral water). Specifically, by adding water to the mineral extract 10B, the diluted liquid 10C is generated and the mineral concentration in the diluted liquid 10C is adjusted. Tap water or underground water is used as the water used for hydration (water for hydration), for example.

In this embodiment, the hydrating process is performed in the hydrating unit 102 (see FIG. 2). Specifically, the water treatment section 102 is configured by a stirring tank 71 having two nozzles 71a and 71b. Then, into the stirring tank 71, the mineral extract 10B is injected from the nozzle 71a, and water for hydration treatment is injected from the nozzle 71b. At this time, by injecting a desired amount of water corresponding to the injection amount of the mineral extract 10B, the concentration of minerals in the diluent 10C (mineral water) is adjusted. Incidentally, the generation of the diluent 10C is not limited to the stirring tank 71, and a tank without a stirring function may be used.

[1-3] Degassing Process In the degassing process, the diluent 10C (mineral water) produced in the hydration process is degassed. Specifically, gases (dissolved gases) such as oxygen and nitrogen dissolved in the diluent 10C are removed.

In this embodiment, the degassing process is performed in the degassing unit 103 (see FIG. 2). Specifically, the degassing unit 103 includes a storage tank 81 that stores the diluent 10C (mineral water), and a vacuum pump 82 that reduces the pressure in the storage tank 81 to a vacuum range. After the diluent 10C is generated in the hydrating process, the diluent 10C is transferred to the storage tank 81. As shown in FIG. After that, the air pressure in the storage tank 81 is lowered to a vacuum area by the vacuum pump 82 . As a result, the dissolved gas (gas such as oxygen or nitrogen) contained in the diluent 10C becomes bubbles and is separated from the diluent 10C and discharged from the storage tank 81 through the vacuum pump 82 .

When the degassed diluent 10C (mineral water) is used as drinking water, the diluent 10C is heated and filtered, and then sealed in a container such as a PET bottle.

According to the manufacturing method and manufacturing apparatus of the present embodiment, the dissolved gas (gas such as oxygen and nitrogen) is removed from the diluent 10C (mineral water) by the degassing process, so that oxygen, nitrogen, etc. in the diluent 10C is removed. Concentration can be reduced. According to the measurement of the amount of dissolved oxygen conducted by the inventor, the amount of dissolved oxygen is about 6.5 mg/l in mineral extract 10B, 6 to 16 mg/l in water for hydration treatment, and diluted before deaeration treatment. The liquid 10C (diluted liquid in the stirring tank 71) was 6 to 16 mg/l, and the diluted liquid 10C after degassing was 0.01 mg/l or less. According to this measurement result, it can be seen that the oxygen concentration in the diluent 10C is remarkably lowered by the degassing process. Therefore, even if the diluent 10C contains a small amount of fungi or algae, they cannot obtain the oxygen, nitrogen, etc. necessary for their growth, and as a result, the fungi and algae do not grow in the mineral water. can be suppressed.

[2] Second Embodiment FIG. 6 is a flow chart showing a method for producing mineral water according to a second embodiment. FIG. 7 is a conceptual diagram showing a mineral water manufacturing apparatus according to the second embodiment. As shown in FIG. 6, in the production method of the present embodiment, a mineral extraction step, a deaeration treatment step, and a hydration treatment step are performed. These steps can be executed respectively by the mineral extraction unit 101, the degassing unit 104, and the hydration unit 105 provided in the manufacturing apparatus (see FIG. 7). Note that the mineral extraction process and the mineral extraction unit 101 are the same as those in the first embodiment, so description thereof will be omitted. The degassing treatment step and the hydrating treatment step will be specifically described below.

[2-1] Degassing Treatment Step In the degassing treatment step of the present embodiment, water used for hydration treatment (water for hydration treatment) is subjected to degassing treatment to generate degassed water. Specifically, gases (dissolved gases) such as oxygen and nitrogen dissolved in water for hydration treatment are removed. Tap water or groundwater, for example, is used as the water for the hydration treatment.

In this embodiment, the degassing process is performed in the degassing unit 104 (see FIG. 7). Specifically, the degassing unit 104 includes a storage tank 83 that stores water for hydration, and a vacuum pump 84 that reduces the pressure in the storage tank 83 to a vacuum region. Water for hydration is stored in the storage tank 83 before executing the hydration process. After that, the air pressure in the storage tank 83 is lowered to a vacuum area by the vacuum pump 84 . As a result, dissolved gases (gases such as oxygen and nitrogen) contained in the water for hydration are separated from the water for hydration as bubbles and discharged from the storage tank 83 through the vacuum pump 84 .

[2-2] Hydration Treatment Step In the hydration treatment step, the degassed water produced in the degassing treatment step is added to the mineral extract 10B. Specifically, by adding water to the mineral extract 10B, the diluent 10C (mineral water) is generated and the concentration of minerals in the diluent 10C is adjusted.

In this embodiment, the hydration process is performed in the hydration treatment section 105 (see FIG. 7). Specifically, the water treatment section 105 is configured by a stirring tank 72 having two nozzles 72a and 72b. Then, into the stirring tank 72, the mineral extract 10B is injected from the nozzle 72a, and the degassed water is injected from the nozzle 72b. At this time, a desired amount of degassed water corresponding to the amount of mineral extract 10B injected is injected to adjust the concentration of minerals in the diluent 10C (mineral water). Incidentally, the generation of the diluent 10C is not limited to the stirring tank 72, and a tank without a stirring function may be used.

When the diluent 10C (mineral water) after the hydration treatment is used as drinking water, the diluent 10C is sealed in a container such as a PET bottle after being subjected to heat treatment and filtration.

According to the production method and production apparatus of the present embodiment, the concentration of oxygen, nitrogen, etc. contained in the water is reduced by removing dissolved gases (gases such as oxygen and nitrogen) from the water for hydration treatment by deaeration treatment. can be lowered. Therefore, by applying hydration treatment to the mineral extract 10B using the water (degassed water), the concentration of oxygen, nitrogen, etc. in the diluent 10C (mineral water) can be reduced. According to the measurement of the dissolved oxygen content conducted by the present inventor, the dissolved oxygen content is about 6.5 mg/l in the mineral extract 10B, 6 to 16 mg/l in the water for hydration treatment (before deaeration treatment), It was about 0.16 mg/l for degassed water and about 2.5 mg/l for diluent 10C (the diluent in stirring tank 72). According to this measurement result, it can be seen that the oxygen concentration in the degassed water is remarkably lowered by the degassing treatment. Moreover, it can be seen that the oxygen concentration in the diluent 10C is lowered by subjecting the mineral extract 10B to the hydration treatment using degassed water. Therefore, even if the diluent 10C contains a small amount of fungi or algae, they cannot obtain the oxygen, nitrogen, etc. necessary for their growth, and as a result, the fungi and algae do not grow in the mineral water. can be suppressed.

In the degassing process, before the hydrating process is performed, not only the water for the hydrating process but also the mineral extract 10B may be degassed. . As a result, the concentrations of oxygen, nitrogen, etc. in the diluent 10C (mineral water) generated in the hydration process can be further reduced.

The above description of the embodiments and modifications should be considered illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims of the utility model registration rather than the above-described embodiments and modifications. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and range of equivalents to the claims of the utility model registration.
