Description

  The present invention relates to a method for efficiently dissolving an inorganic salt, an inorganic oxide, or an organic salt, and a method for producing a liquid composite fertilizer or a mineral water for human consumption using this method.

Fertilizers are used to nourish crops, increase yields and prevent decline in geopower. Fertilizers contain three major elements: nitrogen, phosphorus and potassium, which are essential for plant cultivation.
Nitrogen promotes plant protein synthesis, cell division and proliferation, root development, leaf stem growth, and nutrient uptake. Phosphorus promotes root development, increases the nutrient absorption surface of the root, and activates germination. Phosphorus also promotes plant maturity, increases the yield of fruits and improves the quality of the harvest. Potassium synthesizes carbohydrate and nitrogen compounds and promotes anabolism, root development, flowering and fruiting.

In addition to these major components, ordinary liquid fertilizers contain trace inorganic components such as calcium and boron, and organic components such as sugars such as glucose and fructose, proteins, protein degradation products, amino acids, fermentation products, and vitamins. .
Liquid fertilizers are manufactured by dissolving mineral components, but some of the mineral components required for fertilizers are sparingly soluble, and liquid fertilizers that dissolve mineral components at the desired concentration may not be obtained. Many.

On the other hand, humankind has built up modern civilization by its wisdom along with its evolution, but on the contrary, it has brought about an increase in diseases collectively called modern diseases. One of the causes is a change in diet, that is, a lack of minerals. In the past, they consumed seafood and seaweed rich in minerals. And among these ingested foods, vegetables were grown using the excreta containing undigested nutrients as fertilizer. Besides this, rice, wheat and fruits were cultivated using oil lees, legumes and organic fertilizers. Therefore, it is said that he was healthy by eating foods rich in minerals.
However, nowadays, agricultural products are cultivated mainly with chemical fertilizers and pesticides, and therefore foods containing minerals are decreasing. Many doctors and clinical institutions have reported improvement and recovery of illness due to minerals. According to the Ordinance of the Ministry of Health, Labor and Welfare, essential minerals, calcium, magnesium, sodium, potassium, iron, zinc, copper, chromium, selenium, manganese, phosphorus, iodine, etc. are nourished. Certified as a functional ingredient. In order to cope with the increasing mental burden of modern society, supplementation of mineral components is urgent, but there are few foods that satisfy it, and there are few natural products. Powdered minerals are used as health supplements, but the amount of digestion and absorption is low because of minerals, and if consumed in large quantities, fire extinguisher damage may occur.

  Many natural mineral waters are sold, but the concentration of mineral components in natural water is very low and sufficient mineral components cannot be ingested. Therefore, if there is mineral water in which a relatively high concentration of mineral components is dissolved, an appropriate amount of mineral components can be easily ingested and contribute to health promotion, but such mineral water is not known.

Apart from these, when manufacturing chemicals and chemical products industrially, it is necessary to dissolve the raw material, but when using, for example, an inorganic oxide as this raw material, this inorganic oxide is difficult to dissolve in the solvent, It was necessary to react as a solid or to dissolve by stirring for a very long time.
Japanese Patent Laid-Open No. 7-24278 Japanese Patent Laid-Open No. 10-15369

In the aforementioned fertilizer production, mineral water production, and raw material dissolution, the presence of hardly soluble salts and oxides is an obstacle.
It is known from Patent Documents 1 and 2 that the compound is dissolved under a reduced pressure. However, both of these are used for degassing the dissolved powder and degassing the solvent. However, even if dissolution is promoted, the effect is not dramatic.

  The present invention has been proposed in view of the above, and more efficiently promotes dissolution by conventional decompression to dissolve a metal compound such as salts or oxides in water, and uses this method. It aims at providing the manufacturing method of liquid compound fertilizer, and the manufacturing method of the mineral water for human body intake.

  The present invention relates to a method for dissolving a powdery metal compound in water, wherein an acid is added to the water under reduced pressure to dissolve the metal compound in the water as metal ions, And two or more kinds of metal compounds selected from calcium compounds, magnesium compounds, potassium compounds, zinc compounds, iron compounds, copper compounds and chromium compounds are dissolved in water to which acid is added under reduced pressure, and the corresponding metal ions are dissolved. A method characterized by producing a liquid composite fertilizer to be contained, and two or more metal compounds selected from calcium compounds, magnesium compounds, potassium compounds, zinc compounds, iron compounds, copper compounds and sodium compounds, under reduced pressure A method for producing a mineral water for human consumption containing a corresponding metal ion dissolved in water added with an acid A.

The method of the present invention will be described in detail below.
In the method of the present invention, when a salt or oxide, which is a powdery metal compound, is dissolved in water, it is not only performed under reduced pressure as in the prior art but also by adding an acid to the water. Thereby, deaeration in the powdery metal compound and deaeration of water to be dissolved are performed. Although the reason why the addition of the acid promotes the dissolution of the metal compound is not clear, it can be presumed that the degassing and the circulation of water are promoted by the reduced pressure, and the function of hydrogen ions acts synergistically.

The metal compound targeted by the method of the present invention includes a wide range of inorganic salts, inorganic oxides, and organic salts, and is not particularly limited.
Soluble inorganic salts such as sodium chloride can also be dissolved more rapidly than in the prior art by the method of the present invention, and the molecule can be sufficiently dissociated to exist in water as a single sodium ion or hydrated.
One or two or more metal compounds may be dissolved. When two or more metal compounds are dissolved, only a part of the metal compounds may be dissolved by the method of the present invention.
In addition to sodium chloride, the metal compounds include calcium chloride, potassium chloride, magnesium chloride, manganese chloride tetrahydrate, rubidium chloride, palladium chloride, lithium chloride, bismuth chloride, gold chloride, platinum chloride, zinc oxide, and oxidation. Silver, vanadium oxide, titanium dioxide, silicon dioxide, boron trioxide, iodine trioxide, cobalt acetate, nickel acetate, iron citrate, copper gluconate, bismuth trisulfide, antimony trisulfide, tellurium disulfide, sodium tungstate, molybdenum Examples include, but are not limited to, sodium acid.

The acid used in the method of the present invention is not particularly limited, but citric acid, lactic acid, oxalic acid, acetic acid, propionic acid, malic acid, phthalic acid, hydrochloric acid, nitric acid and the like can be preferably used. The acid used and the concentration to be added depend on the metal compound to be dissolved and the concentration to be dissolved. A suitable acid addition concentration is 1/100 to 1/5 (weight ratio) with respect to the total amount of the metal compound, but is not limited thereto.
In the method of the present invention, the effect is improved as the degree of decompression is increased, but the effect is less improved than the degree of decompression under a decompression condition of 500 Pascal or less. In other words, the object can be almost achieved by a reduced pressure of about 500 Pascals. Therefore, the degree of decompression is preferably 500 to 2000 Pascal, more preferably 1000 to 1500 Pascal, but is not limited thereto.

In actual dissolution, water for dissolution, a powdered metal compound as a raw material, and an acid are placed in a vacuum container, and the mixture is stirred under reduced pressure. The stirring may be performed using a stirrer, but by using the characteristics of the method of the present invention in which dissolution is performed under reduced pressure, stirring is performed by boiling and refluxing water as a solvent by heating. It is preferable. In order to promote dissolution, waves may be added.
As a result, the metal compound is dissolved to obtain water (mineral water) containing metal ions (mineral), and this water can be used as liquid compound fertilizer or mineral water to be taken for health promotion.
In addition, the method of the present invention can be used for various applications for dissolving a metal compound. For example, it can be used for smoothly dissolving a metal compound as a raw material when manufacturing industrial chemicals or chemical products.
In the method of the present invention, acid remains in the resulting mineral water. If this acid residue is not preferred, it may be neutralized using an alkali such as sodium carbonate.

The method of the present invention can be particularly suitably used for the production of a liquid composite fertilizer.
The liquid composite fertilizer preferably contains calcium ions, magnesium ions, potassium ions, zinc ions, iron ions, and copper ions as mineral components, and the preferable content per liter is 2500 mg to 8000 mg, 3000 mg in order. 8000 mg, 3000 mg to 20000 mg, 30 mg to 300 mg, 30 mg to 300 mg and 5 mg to 50 mg.
Usually, a nutritional supplement is added to the mineral water obtained by the method of the present invention to obtain a liquid composite fertilizer. Examples of the nutritional supplement include seaweed extract, brewer's yeast, various amino acids, chitosan, molasses, photosynthetic bacteria, neutralizing bacteria, mycorrhizal fungi, ectomicrobial bacteria, nucleic acids, and photo-Aureus bacteria.
When the liquid composite fertilizer containing a lot of minerals (metal ions) obtained by the method of the present invention is used, it is possible to achieve an increase in the yield of agricultural products, an improvement in quality, and an improvement in sugar content, acidity and flavor. If the raw materials are selected appropriately, liquid composite fertilizer can be produced without using harmful chemical substances.
In recent years, farming has increased in house cultivation, and soil disinfection is performed for continuous cultivation. This can kill useful microorganisms in the soil and prevent crops from growing. Even in such a soil, when the liquid composite fertilizer produced by the method of the present invention is used, a sufficient amount of mineral is supplied to the soil, and the soil can be made suitable for growing a crop.
For good growth of crops, beneficial microorganisms, photosynthetic bacteria that receive sunlight, and soils that have achieved a balance of numerous minerals are essential. The liquid composite fertilizer according to the method of the present invention is optimal for obtaining such a rich soil.
Although the increase in fuel cost in recent years has made house cultivation difficult, the liquid compound fertilizer can achieve an increase in the yield and quality of agricultural products, and can compensate for the increase in fuel cost and generate surplus profits.

The liquid composite fertilizer according to the method of the present invention is basically dispersed around the agricultural products planted in the soil and absorbed from the roots, but in addition to this, the seeds of vegetables, fruit trees or cereals are added to the liquid composite fertilizer. You may immerse in a dilution liquid, and may apply | coat or spread on the leaf surface of a seedling. It can also be used for hydroponics.
When the liquid composite fertilizer according to the method of the present invention is used for cultivation of agricultural products, the following effects are produced.

[General agricultural products]
The liquid composite fertilizer of the present invention is an excellent all-weather type fertilizer that contains many mineral components that enhance the growth of beneficial microorganisms including photosynthetic bacteria, and that can suppress adverse effects to the minimum even if bad weather and insufficient sunlight occur. is there. Therefore, it is also useful for growing agricultural products such as paddy rice, peanuts and buckwheat, and flowers such as plum and apricot other than vegetables and fruits.
Furthermore, if food additives that have been confirmed to be safe are used as raw materials, there will be no adverse effects on the human body and the environment.
Nitrogen as a fertilizer is an essential component in the first half of cultivation, but is almost unnecessary in the second half of cultivation. If a large amount of nitrogen remains, the sugar content, acidity and flavor may be adversely affected. The liquid composite fertilizer produced by the method of the present invention contains a large amount of mineral components, and the balance between nitrogen and other components is improved, so that inconvenience due to residual nitrogen is minimized, and the nitrogen content in the liquid composite fertilizer is reduced. And it can also be set as the fertilizer suitable for the latter half cultivation.
[onion]
Moisture and soil components affect the growth of onions, but if nitrogen remains in the soil in the latter half of the cultivation, it tends to rot after harvest. If the nitrogen content is conserved, the yield decreases, and for example, the yield per 10 ares is 4 tons.
When the liquid composite fertilizer of the present invention is used, the yield can be increased without being affected by the nitrogen component, and 6 to 7 tons can be harvested.
[Cabbage, broccoli, Chinese cabbage]
These are easily affected by the weather, and production increases and decreases every year. When the liquid composite fertilizer of the present invention is used and further production conditions such as irrigation are prepared, the growth is promoted, the harvest time is advanced, the head is hard, the quality is high, and the market value is high.

[Peppers and paprika]
When the liquid composite fertilizer of the present invention is used, the flowering increases and the plant grows beyond the height of the plant height, and large fruits are obtained.
[Strawberry]
Strawberries are usually planted in September and harvested from mid-December until May of the following year. When the liquid composite fertilizer of the present invention is given from around October, flowers will bloom from around November and fruit will be produced without planting new seedlings. This is because if the nitrogen content is not given due to the fertilizer, the old strain will still blossom, and more can be harvested than the new strain. Therefore, replanting every year can be done every two years, and labor can be reduced. Furthermore, the most important increase in sugar content for strawberries is large and highly appreciated.

[sweet potato]
It is said that sweet potatoes do not choose land, but there is a suitable place for sugar content, and sugar content becomes high when cultivated on land with a small amount of mineral components with low nitrogen content. The liquid composite fertilizer of the present invention has a low nitrogen content and is suitable for sweet potato cultivation. In addition, it is said that the reclaimed land is not suitable for cultivation of sweet potato, but the liquid compound fertilizer of the present invention is an industrial raw material such as medium-sized sweet potatoes and shochu, alcohol, starch, dried persimmon paste, persimmon paste in the reclaimed land It is also suitable for the production of sweet potatoes.

The mineral water obtained by the method of the present invention can be directly used by humans to supply mineral components to the human body and can be used as water for food production. For example, when used as washing water for foods such as bread, confectionery, noodles, and vegetables, a mineral component contained in mineral water penetrates into the food and can provide a food containing a large amount of mineral components.
Furthermore, when used as dilution water for seasoning liquids, fruit juice drinks, milk, yogurt, etc., mineral water itself becomes a part of food and is effectively ingested and absorbed.
The effects of mineral water include, for example, reduction of blood sugar level / blood viscosity, recovery from fatigue, prevention of cerebral infarction / myocardial infarction / cancer, hypertension / hypotension / anemia / allergy / rheumatic / constipation / insomnia / whipping Improvement of gastrointestinal disorders, diabetes, menopause, autonomic dysfunction, prostate ataxia, arteriosclerosis, tinnitus, dizziness, stiff shoulders, hay fever, low back pain, etc.

As described above, when the metal compound is dissolved by adding an acid under reduced pressure by the dissolution method of the present invention, even a hardly soluble compound is dissolved in water as a metal ion relatively easily. The metal ion water (mineral water) obtained by this can be effectively used as a liquid composite fertilizer or a mineral water for human consumption. Further, this mineral water may be used for incorporating mineral components into the food by using washing water or dilution water for various foods.
It is expected that the liquid composite fertilizer can greatly change the agricultural form of agriculture in the future.
