Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing mineral water, the purpose of which is to provide a safe and delicious mineral water containing a high quality natural mineral in a well-balanced manner by a simple and easy method. To provide a method for manufacturing water.

[0002]

BACKGROUND OF THE INVENTION The problem of environmental pollution has come to be pointed out on a global scale, and in particular, the problem of tap water pollution in Japan, which is closely related to daily life, has become a serious problem.
As a result of the rapid development of industrial technology, pollutants such as chemical substances emitted from factories, synthetic detergent liquids drained from homes, pesticides emitted from golf courses, and sewage from industrial wastes flow to rivers one after another. The quality of the raw water itself has deteriorated due to the outflow. In addition, rivers are becoming drought due to the tendency of light rain due to the effects of global warming, but on the other hand, the amount of factory wastewater and domestic wastewater does not change even if the flow rate of the river decreases, so pollutants in the river In addition, the concentration of algae has become extremely high, and due to eutrophication of nitrogen, phosphorus, etc. due to dirt, abnormal occurrence of blue-green algae is also occurring. When the raw water from the tap water deteriorates in this way, a large amount of chlorine is added to the water purification plant to purify the water in order to aggregate and precipitate pollutants. High concentration of residual chlorine was detected in tap water at
"Kalky odor" has been generated, or chlorine compounds such as trihalomethanes, which are of concern for carcinogenicity, have occurred, and the "malty odor" has been added to tap water due to the influence of abnormally generated water-bloom. In general, the recognition that tap water is "bad and dangerous" is increasing.

Normally, the human body ingests about 2.6 liters of water per day and excretes the same amount of water, thereby performing metabolism and exchanging nutrients and waste products. Therefore, water is indispensable for humans to sustain life, and as tap water pollution becomes more serious,
Attention has been focused on the creation of "safer and tastier water".

Generally, the criteria for "delicious water" are that the pH is weakly alkaline, that various minerals are contained in appropriate amounts, that carbon dioxide is dissolved, and that there is no chlorine odor (challenge odor) or musty odor. Things are listed. In particular, minerals are considered to be nutrients that tend to be deficient in the Japanese population as a result of westernized dietary habits and drastic changes in the natural environment. Is one. Regarding minerals, the effects on adult diseases and cancer have also been reported, and water containing an appropriate amount of minerals necessary for the human body is becoming an essential condition of "safe and delicious water".

[0005]

2. Description of the Related Art Interest in "water" has increased due to tap water pollution, and various proposals have been made for "safe and delicious water". A typical example is the existence of "mineral water" sold at retail stores. It directly collects the source water of natural groundwater, which is said to be "famous water",
After being sterilized, it is filled in plastic bottles, etc., and the rain and snow pouring from the sky penetrates deep into the ground, and in the process of penetrating the underground rock layer for a long time, high quality natural minerals It is known as safe and delicious water that has dissolved in water, and has been explosively consumed as drinking water as an alternative to tap water in conjunction with the recent health boom. On the other hand, water purifiers, water purifiers, and other appliances that produce "safe and delicious" water by treating "bad and dangerous" tap water at home are being created one after another.
The water purifier is a filter that uses coconut husk activated carbon or the like to remove the "bleaching odor" and "moldy odor" or harmful substances contained in tap water, and also has a sterilizing effect. In addition to such a function of purifying tap water, the device was said to have a mechanism to obtain "alkali ionized water" by electrolyzing tap water to concentrate minerals (alkali ions) such as calcium.

[0006]

However, since the mineral content contained in the above-mentioned "mineral water" is a ground mineral derived from the earth, there is a problem that the living body is out of balance. That is, the mineral content contained in the above-mentioned "mineral water" is Ca, K, N required by the living body.
Since most of the ground minerals are oxides of Si and Al, not the minerals mainly composed of a, Mg, etc., if such "mineral water" is used regularly, the mineral balance of the human body is destroyed. There was a problem that there was a risk of it being done. On the other hand, in the water purifier for the purpose of removing harmful substances and the like, there is a problem that it is impossible to obtain a mineral water rich in minerals that is useful for the living body. Furthermore, in a water purifier that aims to provide alkaline ionized water by electrolyzing tap water, the mineral balance of the resulting water is poor, and it is impossible to obtain drinking water with a mineral balance effective for the living body. There was a problem that was. Moreover, there is a problem in that it cannot be easily installed at home because a certain amount of installation place is required to use this water conditioner. Further, there is a problem in that the above-mentioned water conditioner is complicated because it requires frequent replacement of the cartridge. In view of such circumstances, there has been a demand for the creation of an excellent technique that can easily and easily produce safe and delicious water, which is indispensable for life support and contains high-quality minerals in a well-balanced manner for living organisms, at home. .

[0007]

In the present invention, the pH value is adjusted to an acidic range of 7 or less while blowing carbon dioxide gas into the pretreated water, and the pretreated water in the acidic region has a pH value of 650 ° C or higher and 900 ° C or lower. After mixing and soaking the carbonized carbonized bark at a temperature to elute the minerals in the carbonized bark,
Stop blowing carbon dioxide gas into the pretreated water, again, mixing and immersing the same bark charcoal in this pretreated water, to elute the mineral content in the bark charcoal to prepare mineral-containing concentrated water, By providing a method for producing a mineral water, which comprises diluting this mineral-containing concentrated water at an arbitrary ratio, the above-mentioned conventional problems are completely solved.

[0008]

[Function] Charcoal contains minerals absorbed by the trees from the ground for many years, and remains as ash in the form of soluble carbonates and oxides. In particular, charcoal bark carbonized at high temperatures contains a large amount of natural high-quality minerals. In addition, it is abundantly contained in a well-balanced form for living organisms in a form that is extremely easily dissolved in water. Therefore, by producing mineral water using the minerals eluted from the carbonized bark, it is possible to easily and easily obtain delicious water rich in natural high-quality minerals.

[0009]

The structure of the method for producing mineral water according to the present invention will be described in detail below. In the present invention, charcoal (carbonized bark) is used as a mineral elution material for mineral water. In particular, charcoal is used because the ash content of charcoal contains calcium and potassium as main components, as well as iron, manganese, and other components necessary for physiological activity of living organisms. A large amount of alkaline components (about 60%), and even minute amounts of necessary metallic components such as boron are contained in a minute amount in a well-balanced manner, and these are concentrated three times as much as wood, and these minerals are This is because it is easily soluble and easily absorbed in the form of carbonate or oxide, and contains no harmful component at all. Moreover, it is a material that meets the requirements such as "there is a large amount of alkali content such as calcium and carbon dioxide is dissolved", which is the standard for "delicious water", and can elute ideal natural minerals contained in drinking water. It is because

In general, charcoal has different properties depending on the type of raw material tree, production area, carbonization temperature, and carbonization method, and regarding the mineral content, the type of tree and the portion of the tree,
In the present invention, a bark charcoal carbonized at a temperature of 650 ° C. or higher and 900 ° C. or lower is used, although it varies depending on the soil environment of the producing area. In the present invention, as the charcoal, the bark (bark) carbide located at the outermost part of the trunk of the raw material tree is used as the mineral elution material. The reason is that the bark charcoal has several times more than ordinary charcoal. This is because it is based on the experimental knowledge of the present inventors that they are rich in minerals. Moreover, in this invention, 650
Carbonized bark carbonized at temperatures of ~ 900 ° C is used.

The use of the bark charcoal carbonized at a high temperature of 650 ° C. to 900 ° C. as described above means that the proportion of the elements composing the charcoal changes as the carbonization temperature increases, and the methyl group formed on the surface is changed. , The functional groups such as carboxyl groups and hydroxyl groups are decomposed and released as volatiles to form a hydrophilic surface, and the crystallization of charcoal also proceeds, so the minerals contained in charcoal are pushed out of the tissue. This is because the leachability of minerals to water becomes extremely high as the carbonization temperature rises. Also, since the pH value increases as the carbonization temperature increases, it becomes an optimum material for obtaining mineral water that contributes to health as alkaline water. On the other hand, when the carbonization temperature is low, the charcoal crystals are small, and the functional groups on the surface exhibit chemical bonds, and minerals are difficult to elute, so that it is not preferable to use it as a material for producing mineral water. Particularly, the carbonization temperature is set to 650 ° C. to 900 ° C., because if it is lower than 650 ° C., it is not preferable because the metal component bonded to the surface free radicals of the charcoal is hardly released. On the other hand, if the carbonization temperature exceeds 900 ° C., the metal component bonded to the surface free radicals is solidified and becomes difficult to elute, which is not preferable.

In the present invention, the grain size of the bark charcoal used is not particularly limited, but is 10
Those having a particle size of about mesh or less are preferably used. The reason for this is that if the particle size exceeds 10 mesh, the mineral content contained in the charcoal is less likely to be eluted, which is not preferable. More preferably, a particle having a particle size of about 10 to 320 mesh is used from the viewpoint of mineral elution. Used desirably.

In general, the mineral content contained in charcoal varies depending on the type of tree, the site of the tree, the soil environment of the production area, etc., but the raw material tree and the carbonization method are not particularly limited in the present invention. The carbonized bark obtained by any of the above methods is preferably used. That is, as raw material trees, broad-leaved trees such as Ubamegashi, oak, oak, chestnut (including sumac, goby, nullde, etc.), Kunugi, conifers such as larch, cedar, cypress, pine, or eucalyptus, mangrove, sasanqua, olive, acacia Ordinary trees such as foreign trees can be preferably used, but beech family (Fagacea
e) Oak wood belonging to the genus (Quercus), that is, white oak, red oak, Ubamegashi, Higashihigashi, Kunugi, Quercus oak, Kashiha, Mizunara, etc., is more preferably used due to its high mineral content. In addition, broad-leaved trees of southern timber are more preferably used than those of coniferous trees of northern ocean because of their higher mineral content. On the other hand, there is also no particular limitation on the coal making method, and it is an industrial method such as a kiln method, an open-hearth furnace method, a block kettle method, a carbonization method, a screw furnace method, a fluidized-bed furnace method, or a drilling method, a siding method, A carbonized material by a known carbonization method such as a simple method such as a movable iron plate kettle method or a drum can method can be suitably used without limitation.

In the present invention, the mineral water is manufactured by using the charcoal as described above. First, the first method of the present invention will be described. In the first method, the pH value is adjusted to an acidic range of 7 or less while blowing carbon dioxide gas into the pretreated water. Here, as the pretreated water, water that does not contain any harmful substances such as tap water, purified water, distilled water, and groundwater, and that meets the criteria for drinking water is used. In this way, the carbonized carbonized bark having a particle size of 10 mesh or less and carbonized at a temperature of 650 ° C. or higher and 900 ° C. or lower is mixed and soaked in the pretreated water of which the pH has been adjusted to acidify the mineral content in the carbonized bark. Elute first on the zone side. In this way, the mineral content from carbonized bark is first eluted in the acidic region because the pH at which the mineral content in carbonized bark is eluted.
When the value is higher than 7.0, alkaline earth metals (Ca, K, Mg, Na, etc.) in the bark charcoal are preferentially eluted to raise the pH value of the pretreated water, and as a result, other metals are Ingredient (F
(e, Ze, Cu, Mo, etc.) are not sufficiently eluted, which is not preferable. By setting the pH value of the pretreated water to 7 or less, particularly around pH 5, minerals such as Fe, Ze, Cu and Mo contained in the bark charcoal are sufficiently eluted.

As means for adjusting the pH value of the pretreated water to 7 or less, it is preferable to blow carbon dioxide gas, which is harmless to the living body, in consideration of the fact that the water is drinking water. That is, carbon dioxide gas is blown into the pretreated water to circulate it to adjust its pH value to 7 or less, preferably around 5, and carbonized bark is mixed and immersed in this state. pH
The weight of the bark charcoal to be mixed and soaked in the pretreated water having a value of 7 or less is not particularly limited. As described above, it is more desirable to mix and soak at a temperature of about 20 ° C. Here, the reason why the mixing and soaking weight of the carbonized bark is at least 1 part by weight or more with respect to 100 parts by weight of the pretreated water is that if it is less than 1 part by weight, a well-balanced mineral cannot be sufficiently extracted. This is because it is not preferable. In addition, the bark charcoal used here may be dry charcoal that has been sufficiently dried,
It is preferable because minerals are easily eluted.

On the acidic side, after the minerals from the carbonized bark are eluted into the pretreated water, the blowing of carbon dioxide gas is stopped, and then the carbonized bark similar to the above is mixed and immersed in the pretreated water again. , The minerals in the bark charcoal are eluted on the alkaline side. In this way, the mineral content contained in the carbonized bark is first eluted in the acidic region side and then again in the alkaline region side, so that the mineral component having the ideal mineral balance for the living body is eluted in the pretreated water. It becomes possible.

As described above, the pretreated water from which the mineral content is eluted is filtered to be a mineral-containing concentrated water having a pH value of 7.3 to 7.5. The mineral-containing concentrated water thus obtained is then diluted appropriately at an arbitrary ratio to obtain mineral water. The dilution ratio is not particularly limited, but since the content of minerals affects the taste of drinking water, it is about 300 to 1000.
It is desirable to be diluted at a ratio of about twice.

Next, the second method according to the present invention will be described. In the second method, the particle size is 10 mesh or less, and 650 ° C. or higher and 9 or more in the device for purifying the water to be treated.
Mineral water is produced by filling or mixing carbonized carbonized bark at a temperature of 00 ° C. or less, contacting the treated water with the carbonized bark for at least 30 seconds, and then treating the treated water with purified water. . Here, any existing water purifier or the like is preferably used as a device for performing water purification treatment, and the present invention is not limited thereto.
Arbitrary parts in such a water purifier, particularly, a part that is likely to come into contact with the water to be treated, is filled with the charcoal bark of the above-mentioned property, or the bark charcoal is mixed in the water purifier, and the water to be treated and the bark charcoal are treated. To be contacted before water treatment. The filling amount of the bark charcoal is not particularly limited, and an arbitrary weight of bark charcoal may be used depending on the size of the water purifier to be used. In this way, by bringing the carbonized bark into contact with the water to be treated before the water purification treatment, the mineral content in the carbonized bark is eluted into the water to be treated.

More specifically, for example, the inside of the water purification tank (1) as shown in FIG. 1 is filled with the water to be treated, and the diameter of the water to be treated is at least 3 mm or less, more preferably around 1.5 mm. After the treated water and the carbonized bark are contacted in the tank (1) while stirring for at least 30 seconds, the treated water is treated by the purification filter (2) arranged in the lower part of the tank (1). Clean water treatment,
A mineral water rich in minerals eluted from carbonized bark is produced.

Next, the third method will be described. In the third method, a bark carbonized material having a particle size of 10 mesh or less and carbonized at a temperature of 650 ° C. or more and 900 ° C. or less is filled into a water-permeable bag body, and the bag body is immersed in pretreated water to make a mineral. Leach the minutes to get mineral water. Here, the bag having water permeability is not particularly limited, and a paper used for a normal “tea bag” or the like,
Any material can be suitably used as long as it can leach the eluate from the carbonized bark. The dried bark charcoal is optionally crushed and filled in such a bag,
The mineral water of bark charcoal is leached into pretreated water that satisfies the criteria for drinking water such as purified water and tap water and has been sterilized to obtain mineral water. In this way, when the "tea bag" method in which the bark charcoal is filled in the bag body, mineral water can be easily obtained at home.

The mineral water obtained by the above-mentioned first to third methods can be a safe and delicious mineral water containing an ideal balance of natural minerals by cooling the mineral water as it is or by cooling it in a refrigerator or the like.
