The bamboo charcoal ball 200 may be a bamboo charcoal ball 200 manufactured by the following method.

That is, the bamboo charcoal ball 200 manufactured through the process of material preparation step (S100), mixing dough step (S200), forming step (S300), and curing step (S400) can be used.

1. Material preparation step (S100)

The material preparation step (S100) is a step of preparing materials for manufacturing bamboo charcoal balls (200).

In the material preparation step (S100), bamboo charcoal powder, illite powder, solidifying agent, and seaweed starch may be prepared, and the materials may be prepared by the following method.

The bamboo charcoal powder can be manufactured by pulverizing bamboo charcoal and powdering it. The bamboo charcoal has about twice as much mineral content as regular charcoal, and in particular, silicic acid, the main component of silica gel used as an adsorbent, is higher than that of regular charcoal. Because it contains a large amount, it is used as a deodorant.

In addition, bamboo charcoal is used as a bathing agent because it softens tap water and has a disinfecting effect due to the generation of trace chlorine ions. High-temperature charcoal has a very high far-infrared ray emissivity, is recognized for its electromagnetic wave shielding effect, and has a negative ion generation effect, so it is used in health products. Of course this is possible.

The bamboo charcoal is produced by processing bamboo ash at a high temperature of 400°C or higher, so it is maintained in a sterile state for a certain period of time after production. It contains only a very small amount of inorganic substances and about 60% of the inorganic substances are alkaline components such as calcium and potassium, so it is strongly alkaline. It appears.

In addition, bamboo charcoal is a porous material with a large surface area and very low organic matter content, so even if decay-causing microorganisms enter the bamboo charcoal, they cannot proliferate, and the growth of microorganisms that prefer acidity may be suppressed due to the alkaline nature of the bamboo charcoal. there is.

For example, the bamboo charcoal powder may be bamboo charcoal powder prepared by the following method.

First, after preparing the bamboo, the bamboo can be cut into bamboo chips of 1 to 3 cm in length. Next, the cut bamboo chips are put into a carbonization furnace and then first heated at a temperature of 600 to 700°C for 8 to 10 hours, and the primary heated bamboo chips are separated from the carbonization furnace and heated at a temperature of 20 to 40°C. Primary cooling may be carried out for 20 to 30 hours at this temperature. Next, the primary cooled bamboo chips are secondarily heated at a temperature of 1,000 to 1,200°C for 10 to 12 hours and then secondary cooled at a temperature of 20 to 40°C for 20 to 30 hours to produce bamboo charcoal. You can. Subsequently, bamboo charcoal powder can be manufactured by grinding the bamboo charcoal to a size ranging from 1 to 300 mesh using a known grinder.

The illite powder can be manufactured by pulverizing illite into powder. The illite is a representative natural clay mineral and is defined as a porous mica mineral. It has a thin plate-like structure and has curvedness and elasticity. It has excellent elasticity and adsorption properties compared to other minerals.

The main components of the illite mineral are 57.5% silicon oxide (SiO ₂ ), which removes waste products and fruit sebum in pores, 23.3% aluminum oxide (Al ₂ O ₃ ), which promotes blood circulation, and collagen binding effect. Iron oxide (Fe ₂ O ₃ ) 6.76%, which provides detoxification, stress suppression and relief, calcium oxide (C ₂ O) 0.1%, and sodium oxide (Na ₂ O) 1.21%, which provides osmotic pressure and moisture control functions. , 0.38% of magnesium oxide (MgO), 6.43% of potassium oxide (K ₂ O), and 4.32% of titanium dioxide (TiO ₂ ), MnO, Li, Cr, Zn, and Sr.

In addition, the main function of illite is to adsorb floating substances in water, and because it is anionic, it causes cohesion and precipitation by electrically neutralizing floating particles of positive ions, thereby purifying water and having the ability to adsorb/decompose certain radioactive substances. It adsorbs, deodorizes and decomposes various heavy metals and toxic gases in water/soil/atmosphere, activates cells, enhances immunity, emits a large amount of dissolved oxygen in the water, activates water molecules, and removes water from illite itself. Generates a large amount of negative ions, radiates 93% of far-infrared rays at 40℃, has a bacteriostatic effect on viruses/bacteria/fungi, etc., adsorbs and decomposes various heavy metals/organic substances/toxic substances on the skin, has good elasticity and does not clump. It is known to have excellent adhesion.

The solidifying agent can bind the materials and simultaneously adjust the strength. The solidifying agent may be a solidifying agent prepared by the following method.

To prepare the solidifying agent, first, fly ash, red clay, gelite, and gypsum can be prepared. At this time, the red clay and gypsum can be used to improve the cohesion of fly ash, control the strength by controlling the solidification speed, and improve functionality such as adsorption of contaminants.

Next, a solidifying agent can be prepared by mixing the fly ash, red clay, gelite, and gypsum at a certain weight ratio.

A solidifying agent is prepared by mixing the fly ash, red clay, gelite, and gypsum in a weight ratio of 8 to 12 parts by weight of fly ash, 3 to 7 parts by weight of red clay, 1 to 5 parts by weight of gelite, and 5 to 15 parts by weight of gypsum. It can be.

The fly ash is a particulate material collected by the dust collector of a pulverized coal combustion boiler among the coal ash generated from thermal power plants that burn coal. It does not have its own hydraulic properties, but it reacts with hydrates to densify the structure to improve long-term strength and durability. It is used as a pozzolanic substance to improve

The red clay absorbs and decomposes impurities and pollutants into the space between particles, is rich in oxygen, and emits far-infrared rays. The far-infrared rays emitted from the red clay have a wavelength of 8 to 14㎛, and the far-infrared rays from the red clay promote metabolism by activating cell molecules.

The red clay radiates far-infrared rays and absorbs them into the human body, activating metabolism and blood circulation to prevent aging of the human body and various adult diseases such as chronic fatigue. When far-infrared rays are radiated from the red clay, bacteria are weakened due to the heat effect and can help promote the creation of cell tissue.

The Ge-lite is called pozzolan and contains about 2.0ppm of germanium and a large amount of far-infrared rays and anions. Representative examples include volcanic ash, white silicate clay, and siliceous earth. In other words, the gel light emits far-infrared rays that are about 180 times more powerful than red clay, promotes plant growth, has a humidity control function, emits negative ions and human body energy, has a harmful electromagnetic wave blocking function, and has a deodorizing and sterilizing effect. It also provides a heavy metal neutralization effect.

The gel light acts as an adsorbent to adsorb and remove harmful components, blocks radioactive substances such as radon and electromagnetic waves, can remove odorous components such as ammonia, and has a humidity control function, so it continuously discharges moisture and dries. By increasing the time, the occurrence of cracks due to rapid drying can be suppressed.

The gypsum is a monoclinic mineral, its chemical composition is CaSO ₄ ·2H ₂ O, and it forms rhomboid or columnar crystals, and the gypsum generates heat through a hydration reaction. In addition, the strength can be strengthened as it expands. For example, anhydrous gypsum may be used as the gypsum.

The seaweed starch acts as a natural adhesive to bind the materials, and can exert antibacterial and antifungal effects. The seaweed starch may be seaweed starch prepared by the following method.

First, to prepare the seaweed starch, a starch solution can be prepared by mixing starch and water.

In the starch solution, the starch can provide adhesiveness for binding the composition constituting the seaweed starch. The starch solution can be mixed by mixing 40 to 60 parts by weight of starch and 80 to 100 parts by weight of water. there is.

In addition, the type of starch is not greatly limited, and for example, any one or more selected from the group consisting of corn starch, waxy corn starch, tapioca starch, potato starch, sweet potato starch, rice starch, and wheat starch can be used. .

In addition, the starch includes unmodified starch or specific modified starch. Unmodified starch is starch obtained from a typical starch manufacturing process, and its physical properties (viscosity, heat stability, freeze-thaw stability) are changed by chemical treatment and heat treatment. Modified starch (e.g. acid treated starch, oxidized starch, pre-acetyladipic acid, pre-acetylphosphate, starch octenylsuccinic acid, pre-phosphoric acid, mono-phosphoric acid starch, pre-phosphorylated starch, acetic acid starch, hydroxypropyl phosphate) It is a concept that contrasts with starch, hydroxypropyl starch, etc.). The specific modified starch includes acid modified starch, oxidized starch, acetic starch (Starch Acetate), or starch Octenyl Succinate.

Next, a seaweed solution can be prepared by mixing seaweed, agar powder, and water, and then the seaweed solution can be heated.

Specifically, the seaweed paste solution is prepared by mixing 1 to 5 parts by weight of seaweed, 20 to 40 parts by weight of agar powder, and 400 to 500 parts by weight of water and then heating at a temperature of 90 to 95 ° C. for 5 to 10 minutes. It can be.

In the seaweed solution, Sargassum horneri and Laminaria japonica may be used as the seaweed, and the seaweed includes Sargassum horneri and Laminaria japonica in a weight ratio of 1:1. It can be used by mixing.

The Sargassum horneri is biologically classified into the brown algae plant group, the brown algae family, the order Sargassum family, and is mainly distributed in the western coast of the North Pacific, where it grows in the lower intertidal zone. On the coasts of Korea, parts of the body can be easily observed floating on the surface during low tide. It is the most common species in marine forests, but young specimens are eaten, and in spring, they fall off the bedrock and float on the coast in the form of floating fish.

The Sargassum horneri is yellow-brown in color, and the stem from the button-shaped root is long and sometimes bifurcated and produces branches at the top. Currently, there are reports on the atopic dermatitis suppression effect, anti-inflammatory effect, and heavy metal adsorption effect, and through screening experiments, antioxidant, adipocyte production suppression effect, cancer cell proliferation suppression effect, and anti-blood coagulation effect have been reported.

The kelp ( Laminaria japonica ) is a seaweed of the kelp family of the brown algae plant Kelp order. In addition to various pigments such as carotenes, xanthophylls, and chlorophyll, kelp contains mannitol, laminarin, etc., which are produced through carbon assimilation, and cell walls. It contains a lot of alginic acid, a component of , and contains amino acids such as iodine, vitamin B2, and glutamic acid.

In addition, the kelp is rich in about 50 kinds of various minerals, such as calcium, potassium, sodium, and magnesium, which are easily deficient in modern people. The fiber of the kelp regulates the absorption of nutrients in the digestive system and intestines, and reduces fat in the intestines. It acts to quickly excrete waste products such as cholesterol, excessive salt, heavy metals, carcinogens, and feces from the body.

In particular, alginic acid and laminarin are known to have anti-cancer, anti-hypertensive, anti-thrombotic, anti-blood coagulation, anti-inflammatory, antioxidant, anti-cholesterol, blood flow improvement, lipid metabolism improvement, liver function improvement, intestinal function, and diet effects, etc. It is attracting attention as a type of health functional food material.

The agar powder is manufactured by powdering agar, and the agar powder can be used as a gelling agent. The agar used as a gelling agent is a product made by drying agar made from seaweed of the Agar agar family. It is composed mostly of polysaccharides, with less than 15% protein, 2% ash, 3.5% ash, and less than 0.5% fat. Polysaccharide consists of 70% agarose, a neutral polysaccharide, and 30% agaropectin, an acidic polysaccharide.

In addition, agar has strong hydrophilicity with water, so it has a great ability to maintain moisture in a certain form. Agar usually absorbs about three times as much water and forms a stable gel at a concentration of 0.4%.

In addition, agar easily gels at around 40℃ when reacted with water even in a small amount, and has the property of not melting below 80~85℃, so it can be used even in the summer when the temperature is high and can be stored in a gel state.

Agar is a representative seaweed that has been widely used as medicine, food, and industrial raw materials for a long time, and is a relatively abundant resource with annual domestic production of about 3,600 tons. However, the amount actually used is about 65% of the total production, and most of the rest is neglected, so the added value is low compared to the amount of resources.

Currently, the main ingredient of agar is carbohydrates, and it is used as a food ingredient because it is non-toxic and not harmful to the human body when ingested. Furthermore, as it decomposes well in nature, there is no harmful effect on the environment, so environmental pollution can be prevented in advance. Unlike gelatin, agar extracted from seaweed has a relatively high solidification point and can exist in a gel state even at room temperature, so it can be used as a gelling agent. Compared to others, it can be easily gelled and used.

Next, seaweed starch can be prepared by mixing cypress tree extract with the starch solution and the seaweed solution.

The seaweed-derived starch can be prepared by mixing 80 to 120 parts by weight of starch solution, 80 to 120 parts by weight of seaweed paste solution, and 10 to 30 parts by weight of cypress extract.

The cypress tree extract can be prepared by extracting the cypress tree using a known extraction method. For example, known extraction methods such as reflux extraction method, hot needle extraction method, pressure extraction method, and ultrasonic pulverization extraction method can be used as the extraction method. there is.

Since the composition of the above extraction method is a known technology, detailed description thereof will be omitted for convenience of explanation and clarity of the technical idea of the present invention.

The cypress tree ( Chamaecyparis obtusa ), also called cypress tree, is an evergreen tree of the gymnosperm cone family Cupressaceae, and is native to Japan, but through development, it is widely cultivated as a plantation tree species in the southern region of Korea, with its unique aroma of cypress trees. Therefore, it is used as a deodorant and antibacterial agent.

Phytoncide produced from the cypress tree is a self-defense substance of the plant. It is a substance exhaled or secreted by the plant to resist pathogens, pests, molds, etc., and contains sterilizing and insecticidal ingredients. The constituent of phytoncide is terpene. It is an organic compound composed of phenol compounds, alkaloids, glycosides, etc., and is known to have antibacterial, sedative, deodorizing, and stress-relieving effects. These phytoncides are natural substances, not chemically synthesized substances, are easily absorbed by the human body, and selectively sterilize harmful bacteria to humans.

In addition, phytoncide is known to have numerous functions such as antibacterial, deodorizing, sedative, and stress relieving effects. In addition, phytoncide cleanses and moisturizes the skin with excellent sterilizing, antibacterial, and cleansing effects, and strengthens the body's immune function.
