EXAMPLES The method of the present invention will be described below with reference to examples. [Example 1] 50 kg of humus soil and 50 kg of crushed peat were mixed, and to this was added 1 kg of 96% concentrated sulfuric acid, 1 kg of ethyl alcohol and 10 liters of water containing no harmful impurities such as chlorine, and the mixture was kept at 80 ° C for 2 hours. The mixture was stirred, sealed in a tank, and allowed to stand for 5 days (first aging period) for fermentation and aging. After the first aging period, open the valve of the tank and inject 5 kiloliters of water, stir and aerate 1
It was aged for 0 days (second aging period). During this second aging period, a gel-like substance containing ferric iron floats on the liquid surface, so this is filtered together with other solid matter to obtain a filtrate, and this filtrate is further stored in a tank for 10 days (final aging period). It was left to stand for precipitation and aging. After the completion of the final ripening period, the supernatant in the tank was filtered and purified with a 1-micron filter, and 1% of ethyl alcohol was added as an activator to this to obtain a clear high-concentration mineral liquid.

The properties and components of this highly concentrated mineral liquid were as follows.

As described above, since the high-concentration mineral liquid produced by the method of the present invention has a strong sterilizing action, it is extremely safe to dilute it and use it as soft drink water or water for food production. Also, since it contains various minerals and useful organic substances that are useful for the growth of plants and animals, applying this to soil such as fields and flowerpots promotes the reproduction of useful organisms in the soil, so that the outstanding soil properties are There is a remarkable improvement effect. This soil improvement effect is due to the synergistic effect of so-called soil organic matter and minerals such as amino acids, vitamins, humic acid, etc. contained in this high-concentration mineral liquid. As a metal enzyme containing metal, it has an effect of enhancing physiological functions such as soil microorganisms.

For the same reason, when this high-concentration mineral liquid is used in a fish pond, an aquarium, a cage, etc., the growth of harmful bacteria is restricted, and the proliferation of plankton and microscopic organisms that eat excess food and fish excrement. As a result, the quality of water in the fish farm is maintained at a good level, which not only prevents pollution of seawater but also supplies minerals and useful organic substances to the cultured fish itself. Is enhanced.

Furthermore, the high-concentration mineral liquid produced by the method of the present invention has a deodorizing action equal to or higher than that of a known mineral extraction liquid, and it can be sprinkled and used on food waste discharged from home. Recommended.

It should be noted that the method of the present invention is not limited to the above-mentioned embodiments, but includes many modifications.
Hereinafter, some modified examples will be described. For example, the coal used as a raw material is not limited to peat, as long as it has a low degree of coalification and contains a large amount of minerals and organic matter, lignite, lignite, etc. can also be used, and the mixing ratio with humus is It can be freely changed within the range of 10% or more and 90% or less, depending on the component.

The humus soil is not particularly limited in its components and the like, and artificial culture soil or the like may be used, but generally, humus soil naturally produced in a coniferous forest area which is humid in a cold region is preferable.
Thus, depending on the composition of the raw coal and the humus, if the mixing ratio of any one of them is 10% or less, the amount of extracted minerals and / or organic matter may be unbalanced or insufficient. To become. The mixing ratio of this raw coal and humus is 50
It is desirable to address to.

When the amount of concentrated sulfuric acid added becomes 0.5% or less,
Although the extraction rate of the active ingredient is remarkably reduced, if the addition amount is 5% or more, the pH of the product becomes too low and
Since the humus of the equipment becomes significant, the addition amount should be 0.5% or more 5
% Or less. The amount of sulfuric acid added is 3 when the PH of the product is 3
It is desirable to adjust the value so that it is from 3.8 to 3.8. Depending on the acidity of humus and coking coal, this amount is usually 1
It is around%.

When the amount of ethyl alcohol added is 1% or less, the extraction rate of the active ingredient is remarkably lowered.
Even if it is more than 3%, the extraction rate does not improve, so the addition of more than 3% is useless. The desirable amount of alcohol is usually 2
It is around%. The same applies to the amount of water added.
If it is less than 15% or more than 15%, sufficient aging cannot be performed during the first aging period and the extraction rate decreases. It is generally recommended that the amount of water added be around 10%.

When mixing these raw materials, the temperature is not lower than 60 ° C and not higher than 90 ° C, preferably 8 ° C.
It is recommended to stir at 0 ° C for about 2 hours. When the temperature is 60 ° C or lower, sufficient extraction cannot be performed, and when the temperature is 90 ° C or higher, the active ingredient is lost.

The first aging period is for allowing the extraction reaction and the aging of the extracted components. If this period is less than 4 days, sufficient ripening cannot be achieved, but if it is 10 or more, it is useless. Usually, it is recommended that this first ripening period be 5 to 6 days. If the amount of water injected after the end of the first aging period is 30 times or less the weight of the aging product, the active ingredient cannot be completely extracted. If the amount of water is 100 times or more, the extract liquid becomes too thin, which causes a problem. Usually, the recommended water injection amount is around 50 times.

In the second aging period, the gel-like component is floated and separated by aeration, and the active ingredient is further extracted and aged, and a period of at least 7 days or more, preferably about 10 days is required. However, this period is 15 days or more and is useless.

The final ripening period is mainly for the precipitation of the solid components, and this period is at least 5 days, preferably 10 days. Aging for more than 15 days is useless.
Filtration after the final ripening period is required to be performed by a microfilter. Further, the heat sterilization is carried out by adopting an appropriate method depending on the purpose of use of the mineral liquid, but in the case of beverage use, it is desirable to heat at 80 ° C. for 30 minutes.

The purpose of adding ethyl alcohol to the product is to enhance the activity of mineral water, and the minimum amount is 0.1.
%, Preferably 1%. If the addition amount is 0.1% or less, there is no effect to be observed, and even if it is added in an amount of 3% or more, the cost is increased and the effect of enhancing the activity is not observed.
