It is.

(Points of interest)
Calcium oxide produced by heat-treating shells such as scallops, oysters, pearl oysters, sea bream shells is not limited to nutritional supplements and food additives, it is used for supplementing agricultural soil neutralizers or calcium, or It is used in various fields such as building materials, steel, chemicals, desiccants, heating agents, waste treatment, flue gas demineralization, flue gas desulfurization, wastewater treatment, etc. It is a high substance.

前記表１および２の検査結果により、貝殻の主成分である炭酸カルシウムを、脱炭作用を惹起する９００℃以上まで加熱、焼成して得た酸化カルシウムは非常に活性が高く、充分に乾燥した保管庫に保存した場合でも、時間の経過に伴って空気中の二酸化炭素と結合して次第に炭酸カルシウムへと変化する再炭酸化反応を起こし、長期保存した後には、医薬品や食品、その他各種製品に利用可能な品質基準を確保出来なくなってしまうという欠点を有していることが判明した。 However, as shown in Table 1, the ignition loss of the shell calcium powder at the beginning of production (produced in April 2003) was 2.9%, which is the voluntary standard of the third edition existing additive (Japanese food additive) Under the inspection based on the association), those that were in conformity with the inspection standard (10% or less), as shown in Table 2, are about 4 years after production (March 2007). In spite of being stored in an environment maintained at a low temperature, the loss on ignition was 32.0%, and the quality as a food additive could not be satisfied, greatly reducing the quality.

According to the test results in Tables 1 and 2, calcium oxide obtained by heating and baking calcium carbonate, which is the main component of the shell, to 900 ° C. or higher that induces decarburization is very active and sufficiently dried. Even when stored in a vault, it undergoes a re-carbonation reaction that combines with the carbon dioxide in the air over time and gradually changes to calcium carbonate. It has been found that there is a drawback that it is impossible to secure quality standards that can be used in the future.

(Conventional technology)
In order to overcome such circumstances, for example, as in the invention described in Patent Document 1 (1) described later, a calcium hydroxide powder or a calcium carbonate powder having a particle size of 300 μm or less is granulated into granules having a particle size of 1 mm or more. Then, the granulated body is calcined at a temperature of 400 to 950 ° C. for 30 minutes to 2 hours under normal pressure, and is contacted with carbon dioxide at the subsequent stage of the calcining, or after calcining, further in a carbon dioxide atmosphere, 400 to 700 Calcium oxide comprising a highly active calcium oxide porous particle having a specific surface area of 5 m 2 / g or more and a particle size of 1 mm or more and a calcium carbonate coating layer formed on the surface thereof by treating at a temperature of 10 ° C. until the carbonation rate is at least 10%. It is a porous granular composite, and the surface of the highly active calcium oxide porous body is coated with a calcium carbonate layer. In other words, a calcium oxide porous granular composite is obtained which can obtain a composite exhibiting good stability against moisture and other reactive gases over a long period of time without impairing the activity of the highly active calcium oxide porous body. And a method for producing the same, and a portion of the purple root of the purple family, as seen in the “skin cosmetic” invention disclosed in Patent Document 1 (2), is purified water or ethanol. , By using a general method of cooling with an organic solvent such as 1,3-butylene glycol and extracting for 3 to 6 days, the pH containing shikonin and shikonin derivatives is red to reddish purple in an acidic to neutral range. Is added to the cosmetic at a ratio of 0.01 to 0.5%, preferably 0.05 to 0.2%, so that the skin cosmetic is allowed to stand at room temperature. Sutra Effect of enhancing the stability is disclosed.

However, as shown in the former Patent Document 1 (1), the surface of the calcium oxide porous body is coated with a calcium carbonate layer, and the carbonation rate is at least 10%, preferably It is said that a coating corresponding to 20 to 40% is necessary, and if the rate of carbonation is less than this, the stabilizing effect becomes insufficient, and if the carbonation proceeds further, the activity of calcium oxide decreases. It must be made into a granular material having a particle diameter of 1 mm or more containing 10 to 40% calcium carbonate, and the total amount of production cannot be made high-purity calcium oxide. ing.
In addition, a purple water extract obtained by using purified water such as that represented by the latter patent document 1 (2) or an organic solvent such as ethanol or 1,3-butylene glycol is blended at a predetermined ratio. However, due to skin cosmetics with improved stability over time, an extract component derived from purple root, which is a kind of traditional Chinese medicine, has been found to improve the long-term preservation of cosmetics. Various techniques such as whether or not to have a function of suppressing the recarboxylation reaction of calcium oxide and what kind of mixing method is possible have not been immediately conceived.

(Awareness of problems)
As described above, various calcium oxide composites that have been proposed so far, and various production methods for producing them, for example, are granular materials having a particle size of 1 mm or more, and an active carbonation reaction is performed on some percent of the surface. To form a calcium carbonate coating layer to prevent recalcification of the calcium oxide in the center of the granular material. It becomes a complex of calcium oxide and calcium carbonate, making it impossible to use when pure calcium oxide is required, and high quality such as chemicals, foods, and pharmaceuticals is required. In such a case, there is a fatal defect that there is a risk of being evaluated as calcium oxide having low purity. Whether or not the technology for improving the stability over time by blending purple root extract obtained using an organic solvent such as nor and 1,3-butylene glycol is useful for suppressing the recarbonization reaction of calcium oxide, or The technical issues such as the purpose of the known purple root extract to be mixed with calcium oxide have not been verified at all, and the problem of suppressing the re-carbonization reaction of calcium oxide. However, since it does not belong to the technical category that can be predicted from these existing technologies, the technology that can reliably prevent the deterioration of quality caused by the re-carbonation reaction due to long-term storage of calcium oxide has not yet been elucidated. The fact is that there is no.

(Object of invention)
Therefore, the present invention can effectively suppress the re-carbonization reaction even when calcium oxide powder calcined and cationized at a high temperature is stored for a long period of time, and is highly effective even in a normal warehouse environment. Judging whether it is possible to develop a new calcium production technology that can maintain the quality for a long period of time, we have begun to develop and research it quickly and have repeated trial and error over many years and many trials and experiments. As a result, this time, it finally succeeded in realizing a shell calcium powder body having a novel structure and a novel production method thereof. It will be described in detail.

(Structure of the invention)
As can be clearly understood from the embodiments representing the present invention shown in the drawings, the shell calcium powder of the present invention basically comprises the following constitution.
That is, it is a calcined and cationized calcium oxide powder of 5 to 10 μm, and at least the surface of each fine powder particle that can come into contact with air is coated with an antibacterial Kampo-derived component, impregnation layer or chemical reaction layer. It is a shell calcium powder having a configuration in which any one or a composite layer thereof is formed.

    When the shell calcium powder body consisting of this basic structure is expressed in different expressions, shells mainly composed of calcium carbonate that has been washed and dried in advance are heated within a temperature range of 900 ° C. to 1000 ° C., A shell calcium powder having a constitution in which a predetermined ratio of antibacterial Chinese medicine-derived components mixed in a solvent such as alcohol and extracted into calcium oxide baked into fine powder is mixed.

    More specifically, shells mainly composed of calcium carbonate that has been washed and dried in advance are heated and baked in a temperature range of 900 ° C. to 1000 ° C. to obtain fine powdered calcium oxide. The antibacterial Chinese herb-derived components that are extracted by mixing in a solvent such as the above are mixed together, and at least the surface of each fine powder particle that can be contacted with air is coated with the antibacterial Kampo-derived component. Then, a shell calcium powder having a structure in which any one of the impregnation layer and the chemical reaction layer or a composite layer thereof is formed.

(Related invention)
In relation to the above-mentioned shell calcium powder, the present invention also includes a production method thereof.
That is, impurities adhering to the surface of shells mainly composed of calcium carbonate are removed by clean water cleaning (1), heated to 100 ° C. to 120 ° C., dried (2), and then in a temperature range of 900 ° C. to 1000 ° C. The shell fired product heated and baked (4) in the inside is naturally cooled to room temperature (5), then pulverized to a particle size of 5 to 10 μm (6) to remove remaining impurities (7), The remaining predetermined amount of the cationized calcium oxide powder is mixed (10) with a predetermined proportion of antibacterial Kampo-derived components extracted (8,9) mixed in a solvent such as alcohol. This is a method for producing the shell calcium powder body which forms the basis of the present invention.

    More specifically, the manufacturing method of this shell calcium powder is to remove impurities adhering to the surface of shells mainly composed of calcium carbonate (1), and then to 100 ° C. to 120 ° C. After heating and drying (2), selecting only shells and shell pieces of 15 mm or more from among them (3), heating and baking within a temperature range of 900 ° C. to 1000 ° C. (4) After natural cooling (5), the remaining impurities are removed (7) by pulverizing to a particle size of 5 to 10 μm (6), and a remaining amount of the cationized calcium oxide powder is added to a solvent such as alcohol. Mixing a certain proportion of antibacterial Kampo-derived components mixed into the extracted (8,9) form (10), and at least the surface of each fine powder particle that can be contacted with air from the antibacterial Kampo-derived component Co Ingu layer, any one of the impregnation layers or chemical reaction layer also obtained by forming these composite layers, it is possible that the method for producing a shell calcium powder body forming the base of the present invention.

    As described above, according to the shell calcium powder body of the present invention, the calcium carbonate coating layer can be obtained by forming a calcium oxide porous granular composite having a particle size of 1 mm or more having a calcium carbonate coating layer. However, in order to secure a calcium carbonate coating layer with a stabilizing effect, a sufficient carbonation rate must be ensured, and the purity of calcium oxide is greatly increased. It has the disadvantage that it is difficult to produce a fine powder with a particle size of less than 1 mm, such as being difficult to use in pharmaceuticals and foods. The technology of improving the stability over time by adding purple root extract extracted from purple root, which is a kind of potato, can suppress the re-carbonation reaction of calcium oxide obtained by baking calcium carbonate. Whether or not, the effectiveness of blending purple root extract into calcium oxide has not been established at all, and the firing technology to solve these has not been developed yet, but as described above, firing, A layer consisting of antibacterial Kampo ingredients is formed on at least a surface of the cationized calcium oxide powder that can be contacted with air. By using a highly safe ingredient called Kampo, it can be used in a wide range of fields such as pharmaceuticals and foods. It can be provided to the market as a high-purity calcium oxide powder that can be used, and the Chinese herbal medicine component that covers the surface even after long-term storage at room temperature suppresses the re-carbonation reaction of the calcium oxide powder, and the quality The excellent feature of reliably preventing the deterioration of the material is exhibited.

    In addition, shells mainly composed of calcium carbonate, which has been thoroughly washed in advance and cleaned to remove impurities adhering to the shell surface and dried, are heated and fired within a temperature range of 900 ° C to 1000 ° C. It is possible to make each work process of washing, drying, and baking, and the energy consumption required for it most efficient, and also mix a certain proportion of antibacterial Kampo-derived components mixed in alcohol and other solvents. Combined and pulverized into a fine powder, components derived from antibacterial Kampo can be efficiently extracted in a short time and can be kneaded simultaneously with the pulverization of the calcined calcium oxide pieces. Moreover, it is possible to provide a high-quality and low-cost shell calcium powder by preventing re-carbonation during the production process.

    Furthermore, the calcined calcium oxide piece is mixed with a predetermined ratio of the antibacterial Chinese medicine-derived component and pulverized into fine powder, and the surface of each fine powder particle is coated with the antibacterial Chinese medicine-derived component. In addition, any one of the impregnation layer and the chemical reaction layer or a composite layer thereof is formed, and recalcification with the aging of the calcium oxide powder body is surely prevented in any layer form. It will be possible.

    Further, according to the method for producing a shell calcium powder of the present invention, impurities attached to the surface of shells are carefully removed by clean water washing and heated to 100 ° C. to 120 ° C. and dried. Sanitary manufacturing conditions can be set at the initial stage of the process, and impurities can be prevented from bursting and water vapor generation during the subsequent firing process, ensuring safer and more efficient heating. In addition, after naturally cooling the calcium oxide pieces that have been cationized by firing, the particles are pulverized to a particle size of 5 to 10 μm, impurities are removed, and the Chinese herb extract components are mixed together. Impurities can be removed efficiently, the recarbonization reaction during production can be effectively suppressed, and the production process and man-hours can be greatly reduced to realize more efficient production. That.

    Furthermore, only shells and shell pieces of 15 mm or more are selected and fired from shells heated and dried after clean water washing, and shells or powders of 15 mm or less are mixed to clog gaps. Compared to the case of baking in a state of being clogged or clogged, the shell and shell pieces are kept as independent as possible and the whole surface can be burned evenly, and the emission of carbon dioxide is more efficient. The excellent effect is that the powder is obtained by pulverizing the calcium oxide, which is calcined while maintaining it in an accelerated manner, resulting in high purity calcium oxide. Play.

In implementing the present invention having the configuration as described above, the best or desirable mode will be described.
Shells are shells mainly composed of calcium carbonate, and can be shells of shellfish that are consumed in large quantities such as scallops, oysters, oyster shells, sea bream shells, clams, etc. It is also possible to substitute various things such as shellfish, eggshells of birds, bones of fish, shells of crustaceans such as crabs and shrimps, sea stars, and bones of livestock.

    Herbal medicine is a herbal medicine that uses natural products that exist in nature such as plants, animals, minerals, etc., and is a medicine that is generally prescribed by doctors during a Kampo medical examination. Medium, must have antibacterial properties, such as purple root, echinacea, wrinkle, dokudami, weeping, agar, tensento, shiso leaves, ginkgo leaves, bamboo leaves, wild chrysanthemum flowers, golden silver flowers, safflower, licorice, gold leaf , Mulberry, glaze, carrot, other herbal medicine, rosehip, chamomile, lemongrass, cinnamon, lavender, rosemary, other herbs, etc. An extracted component extracted with methanol, ethanol, methyl alcohol, isopropyl alcohol, distilled water or the like is used.

    Clean water cleaning is a process of removing impurities adhering to the surface of natural shells and other shells to a sanitary state, and it may be cleaned manually using a brush or the like one by one. There is no problem, but it is desirable to use various cleaning machines such as trommel in consideration of work efficiency. In any case, the cleaning effect is fully exhibited as much as possible considering the baking condition and quality after baking. I have to do so.

    Drying after washing is performed using various equipment and facilities such as drying chamber, steam chamber, hot air blowing, electric furnace, gas furnace, etc., and there is no chemical change in calcium carbonate, the main component of shells. In addition, it should be 100 ° C. or higher and 120 ° C. or lower under atmospheric pressure at which moisture can be evaporated, and should preferably be 100 ° C. or higher and 115 ° C. or lower. Although it is possible to set the following, it is sufficient if the heat treatment by an economical apparatus or facility is possible as long as 100% drying is possible, and it is used for foods and pharmaceuticals. When producing calcium powder, it is necessary to avoid drying with a desiccant or other chemicals, and it is necessary to perform a hygienic and safe drying process. Spray compressed air or the like at the beginning of the drying process. Shell After skipping the water adhering to the heating, it is possible to more quickly and efficiently drying the proceed to drying.

    The firing step is a step of heating to 900 ° C. or higher at which carbon dioxide is released from calcium carbonate, which is the main component of the shells, and chemically changing to calcium oxide, and the heating upper limit temperature is physically the melting point of calcium carbonate. Although it can be heated up to 2572 ° C., in consideration of productivity and economy, it should be kept at about 1000 ° C., and the firing process may be carried out in a gas furnace or an electric furnace, In order to obtain high-purity calcium oxide, only shells and shell pieces of 15 mm or more that have been sufficiently washed and dried are selected and fired, and individual independence is ensured as much as possible to ensure gaps. Thus, the entire individual surface should be able to be uniformly heated and fired, and the shells become agglomerated with each other during the firing process, and carbon dioxide release at the center of the mass. There phenomena that would alienated, it is important to avoid as much as possible.

The pulverization process is a process in which the fired shell baked product is naturally cooled to room temperature and then pulverized to a particle size of 5 to 10 μm, and can be set to remove impurities at the same time. It is also possible to proceed with the removal of impurities, and at the same time, a process of mixing a predetermined ratio of antibacterial Kampo-derived components that are extracted and mixed in a solvent such as pulverization treatment and impurity removal It is also possible to do this.
Impurities can be removed using a centrifuge, vibrating sieve, wind sorter, or other machine, and it is possible to use the impurity removal function that comes with the pulverizer. In this case, the pulverization process and the impurity removal work are performed simultaneously.

In the process of mixing the pulverized calcium oxide fine powder particles with a predetermined proportion of the antibacterial Chinese herb components that are extracted by mixing them in a solvent such as alcohol, a surface that can contact at least air of each of the calcium oxide fine powder particles In addition, a coating layer, an impregnation layer, a chemical reaction layer or a composite layer composed of the antibacterial Kampo-derived component is processed to form a high-speed mixer, a high-speed stirring mixer, a high-speed mixer. A mixing granulator, a low speed mixer, or other devices capable of mixing fine powders can be used, and it is preferable to prevent re-carbonation by mixing with Kampo extract components immediately after the pulverization.
In the following, the structure of the present invention will be described in detail together with an embodiment representative of the present invention shown in the drawings.

The example shown in the flowchart of the manufacturing method of the shell calcium powder in FIG. 1 is that the shells mainly composed of calcium carbonate which has been washed (1) and dried (2) in advance are within a temperature range of 900 ° C. to 1000 ° C. After heating and baking (4) and cooling the cationized calcium oxide pieces to room temperature (5), impurities are removed (7) after pulverizing treatment (6), and in a solvent such as alcohol. Mixing a predetermined proportion of antibacterial Kampo-derived components mixed and extracted (8, 9) (10), and coating these antibacterial Kampo-derived components on at least the surface of each fine powder particle that can contact air 1 shows a typical embodiment in the method for producing a shell calcium powder body of the present invention in which any one of a layer, an impregnation layer and a chemical reaction layer or a composite layer thereof is formed. .
In the following, the structure will be described in accordance with the method for producing a shell calcium powder of the present invention.

    Shellfish such as scallops, oysters, sea breams, pearl oysters, etc., whose main component is calcium carbonate, are supplied to Trommel and continuously rotated and washed with water to clean up trash, lime algae, barnacles, and sand. After sufficiently removing impurities such as (1), the shells are heated to 100 ° C. to 115 ° C. and dried (2) using a hot air dryer.

    After being 100% dry, only shells and shell pieces of 15 mm or more are selected from these shells and shell pieces (3) and stored in a gas furnace (Osawa Gas Furnace Co., Ltd., etc.) for 900 hours over 12 hours. Heat to a temperature range of ℃ to 1000 ℃, and further baked (4) while keeping within the same temperature range for 1 hour to obtain a shell baked product, or an electric furnace (manufactured by Thermal Co., Ltd., etc.) ) And heated to a temperature range of 900 ° C. to 1000 ° C. over 10 hours, and further fired (4) while maintaining within the same temperature range for 1 hour to obtain a fired shell.

    The fired shell (calcium oxide pieces) thus fired is in a state where the shape of the shell has collapsed due to high temperature, and after furnace cooling (natural cooling) (5) to room temperature over about 24 hours, (6 manufactured by Micron Co., Ltd.) and processed into a fine powder of 5 to 10 μm (6), and impurities are removed using a centrifuge or sieve (7) to increase the purity of the calcium oxide powder. After raising to the standard, supply to high-speed mixers (such as Sugiyama Seisakusho)

    The high-speed mixer uses a predetermined amount of calcium oxide powder that has been cationized and is a dried product of Murasaki family Murasaki, which is a root of purple root (scientific name: soft shikon, ingredient Shikonin) as an antibacterial Chinese medicine. More than 1% by weight of an appropriate amount of water and leaves mixed in ethyl alcohol (solvent) (mixed at a ratio of 150 cc of ethyl alcohol to 3.3 g of purple root) and soaked for 24 hours (8) (2% by weight or more and 3% by weight or less) When the ratio is added (9) and evenly stirred and mixed (10), the temperature of the calcium oxide powder increases to 80 to 90 ° C. due to friction during the high speed mixing process. The alcohol component is evaporated, and only the remaining purple root extract component adheres to the surface that can contact at least air of each of these calcium oxide fine powder particles, and forms a coating layer. Either an impregnation layer is formed by permeation, or a chemical reaction layer is formed by chemical change, or a composite layer thereof is formed.

    The shell calcium powder produced in this way is packaged and shipped in appropriate amounts for chemicals, pharmaceuticals, food additives, nutritional supplements, various industrial chemicals, various agricultural chemicals, etc. (11 ).

(Operation of Example 1)
As shown in FIG. 1, the shell calcium powder body of the present invention having the configuration as described above, and the method for producing the shell shell, have a shell of 15 mm or more from a shell group that has been subjected to clean water cleaning (1) and drying treatment (2). Only shell pieces are selected and heated and fired (4), and shell pieces of less than 15 mm and shell powder bodies are concentrated and lump-shaped, and the heating effect is not fully distributed. This prevents the calcium carbonate from remaining in the central part of the mass after firing, thereby reducing the productivity and quality of the high-purity calcium oxide powder.

    In addition, firing (4) temperature is limited from the lowest temperature of 900 ° C, which releases carbon dioxide from shells, to 1000 ° C, which can suppress fuel consumption and power consumption to the most economical one without damaging the furnace. Calcium oxide powder can be produced economically, pulverized to 5-10 μm (6), impurities removed (7), and then purple root extract component is added (9). The amount of alcohol contained in the purple root extract component is evaporated and extinguished by using frictional heat generated in the stirring and mixing step (10) while minimizing the amount and unnecessary chemical or physical due to the alcohol component. Suppresses the reaction.

(Effect of Example 1)
The shell calcium powder produced by the production method of Example 1 having the above-described configuration had an ignition loss of 3.3% at the beginning of production (produced in April 2003) as shown in Table 3. However, as shown in Table 4, the loss on ignition was maintained at 3.6% after being produced for about 5 years (inspected in February 2008) after production. Compared to the fact that the conformity standards can be met at a high level, and the conventional type shown in Tables 1 and 2 becomes unusable as a food additive after about 4 years, about 5 years It has been proved that it can be used as a food additive with a quality almost the same as that immediately after production even after a lapse.

In addition, as shown in Table 5, 5% by weight of the shell calcium powder fired by the electric furnace of Example 1 is added to agricultural water (raw water) in which 8.4 × 105 general bacteria are present in 1 ml. As a result of stirring for 5 minutes, it was found that the number of general bacteria in 1 ml was greatly reduced to 3.4 × 10, and it was proved that general bacteria in agricultural water could be greatly reduced.

また、同表６中に示すように、農薬液スミチオン（商品名）（希釈倍率５００倍）に２分間浸漬したチンゲン菜（４５ｇ）を４時間自然乾燥後、水道水１ｌ中に、２分間攪拌した上、３分間放置した場合残留農薬が０．１４ｍｇ／ｌだったのに比較して、同一条件のチンゲン菜（４５ｇ）を、実施例１の貝殻カルシウム粉末体（表中漢方カルシウム−Ｚ１０）の１０００倍液（水溶液）１ｌ中に２分間攪拌した上、３分間放置した場合の残留農薬が０．０３５ｍｇ／ｌとなった。 Furthermore, as shown in Table 6, the chingen (45 g) soaked in the pesticide liquid Darzbang (trade name) (dilution factor 500 times) for 2 minutes was naturally dried for 4 hours and then stirred in 1 l of tap water for 2 minutes. Above, when left for 3 minutes, the pesticide residue (45 g) under the same conditions was compared with the amount of pesticide vegetables (45 g) of the same condition compared to 0.060 mg / l of residual agricultural chemical. After stirring for 2 minutes in 1 l of a 1000-fold solution (aqueous solution), the residual pesticide when left for 3 minutes was 0.013 mg / l.

Moreover, as shown in the same Table 6, the Chingen vegetables (45 g) immersed in the agricultural chemical liquid Sumithion (trade name) (dilution factor 500 times) for 2 minutes was naturally dried for 4 hours and then stirred in 1 l of tap water for 2 minutes. In addition, when left for 3 minutes, the pesticide residue (45 g) under the same conditions was compared with the remaining pesticide residue of 0.14 mg / l, and the shell calcium powder of Example 1 (Kampo calcium-Z10 in the table). The resulting pesticide was 0.035 mg / l after stirring for 2 minutes in 1 liter of an aqueous solution of 1000 times (aqueous solution).

    Thus, from the test results of Table 6, it was found that the pesticides that had penetrated into the vegetables could be greatly purified by the purified water obtained by diluting the shell calcium powder according to Example 1, and natural foods that can be used as foods. The shell calcium powder, which is made by baking the shell material and adding the safe and sanitary antibacterial Kampo ingredients to these fine powders, is also excellent in food hygiene quality, and contains Kampo extract ingredients. It can be said that it has been proved that the performance deterioration due to the above is exerted as a cleaning agent for vegetables in which residual agricultural chemicals are a concern.

(Conclusion)
As described above, the shell calcium powder body of the present invention and the method for producing the same make it possible to achieve the intended purpose even by the novel structure, and are easy to produce. In addition, it can be manufactured at low cost by mixing antibacterial Kampo extract ingredients that can also be used as food and pharmaceuticals, and its long-term shelf life is greatly enhanced, and it is generally used without using a special storage It can be stored in a long-term warehouse and can be provided much more economically than conventional products, so it is highly pure and can be stored for a long period of time, making it excellent in safety and hygiene. In addition to the chemical and pharmaceutical industries that want to provide calcium oxide, the food industry, the industrial industry, the agrochemical industry, and high quality and safe pharmaceuticals and dietary supplements from these various industries , Food additives, various industrial products, agricultural products, companies that want to provide all kinds of products such as detergents and disinfectants, local governments, schools, households, etc. It is expected to be.
