Description

Far-infrared radiation liquid composition manufacturing method {METHOD FOR MANUFACTURING LIQUID COMPOSITION RADIATING FAR-INFRARED}

The present invention relates to a method for producing a liquid composition emitting far infrared rays. Specifically, it relates to a method for producing a liquid composition emitting far-infrared rays using bran such as rice bran or rice husk.

In general, far-infrared rays are electromagnetic waves having a long wavelength among infrared rays (0.76 ∼ 1000 µm), which is generally in the range of 4 ∼ 1000 µm. Such far-infrared rays are radiated in a large amount by sunlight, and even a small amount is radiated by far-infrared radiation materials. Far-infrared rays have a stronger thermal action than visible rays, and radiant energy rapidly heats the black body by heat transfer, and is a useful electromagnetic wave widely used because of its high energy saving effect. Since far-infrared energy has a property of being absorbed by a living body, the absorbed energy is known to facilitate the physiological function of the human body by supplying energy required for activation of body fluids, stimulation of molecules in the living body, or physiological functions.

Radiators emitting far-infrared rays having such characteristics are generally used in the fields of chemical industry such as clothing and bedding, tableware and cookers, various construction materials, drying agents for paints, dispersion aids, porous adsorbents, food processing and preservation fields, as well as agriculture and It is also used in the fields of horticulture and livestock, and is used in various health aids such as heat treatment agents such as saunas, heat massagers, mats and girdles.

Conventional products using a far-infrared ray emitting material have mainly manufactured a radiator obtained from a mineral powder in a liquid state by using a mineral powder radiator as a solid.

Referring to Figures 1 to 4, the method for producing a far-infrared radiation liquid composition according to an example is a first high-pressure heating step (S100, S1100), a first condensate acquisition step (S300, S1300), alkali reduction step (S500, S1500) And obtaining a liquid composition (S700, S1700, S2700). We look at each step in detail.

1st high pressure heating step (S100, S1100)

First, in the first high-pressure heating step (S100, S1100), bran and water are mixed and then heated at a high pressure first to remove moisture and organic matter. For example, referring to FIG. 4, the bran may be any one of rice husk and rice bran, or a mixture of both. For example, the bran may be a powder of rice husk, rice husk, or a mixture of both. For example, water to be mixed with bran may be pure water such as distilled water.

The mixture of bran and water is firstly heated at high pressure to remove moisture and organic substances other than the silicon (Si) component related to far-infrared radiation among the components contained in the bran. It is a process of steaming a mixture of bran and water under high pressure to remove moisture and organic matter. In this process, some moisture and/or organic matter may remain in the remaining residue.

For example, referring to FIG. 2, in the first high-pressure heating step (S1100), it may be heated to a temperature of 80 to 120°C at a pressure of 4 to 6 kgf/cm ² . By heating to a pressure of 4 to 6 kgf/cm ² and a temperature of 80 to 120° C., for example, the holder on the outlet of the container is opened to evaporate moisture and organic matter into a gaseous form. For example, preferably, the pressure may be maintained at about 5 kgf/cm ² and the temperature may be maintained at about 100°C. For example, the high pressure/high temperature heating time may be about 3 hours.

For example, in one example, in the step of firstly heating at high pressure (S1100), a mixing weight ratio of bran and water may range from 1:1.5 to 3. For example, the mixing weight ratio of bran and water may be a degree to which the bran is immersed in water through mixing, for example, the weight ratio of water to bran may be about 2 or so. At this time, the mixture of bran and water may be heated for 2.5 to 3.5 hours at a pressure of 4 to 6 kgf/cm ² and a temperature of 80 to 120°C. For example, the heating time may be approximately 3 hours, and may be adjusted according to pressure and temperature.

For example, in FIG. 2, the first high-pressure heating step (S1100), the step of obtaining the first condensate (S1300), the step of lowering the alkali (S1500), and the step of obtaining a liquid composition (S1700) are all shown, but the specific configuration of each step is It can be implemented as a separate embodiment.

First condensate acquisition step (S300, S1300)

Next, the steps of obtaining the first condensate (S300 and S1300) will be described with reference to FIGS. 1 to 4. In the first condensate obtaining step (S300, S1300), the residue remaining after the first high-pressure heating is secondarily heated to high pressure by a distillation method to obtain a first condensate.

At this time, since it is heated by the dry flow method, the residue after the first high pressure heating is heated at high pressure/high temperature in a state where there is little air. For example, the drying method is used as one of the methods for obtaining extract from grasses and the like, and is used in the process of obtaining a liquid substance including a far-infrared radiation component from bran in the present invention.

The first condensate is obtained by collecting and condensing the gas generated by secondary high pressure heating by the distillation method. At this time, the obtained condensate contains, for example, a high concentration of silicon (Si) component.

For example, referring to FIG. 2, in the step of obtaining the first condensate (S1300), the residue remaining after the first high-pressure heating may be heated to a temperature of 150 to 210°C at a pressure of 4 to 6 kgf/cm ² .

The first condensate is obtained by collecting and condensing the gas generated by heating the residue at a pressure of 4 to 6 kgf/cm ² and a temperature of 150 to 210°C in a container with almost no air by the distillation method. At this time, preferably, the pressure may be maintained at about 5 kgf/cm ² and the temperature may be maintained at about 200°C.

The second high pressure/high temperature heating time can be sustained enough to obtain sufficient first condensate from the residue in the vessel.

Alkali reduction step (S500, S1500)

In the alkali reduction step (S500, S1500), water is added to the first condensate and the alkali is reduced. For example, at this time, the water mixed with the first condensate may be pure water such as distilled water. Since the first condensate is high alkali, the alkali level is lowered to an appropriate range before catalytic reaction in the next step. For example, when the alkali level is lowered by only diluting water, the content of the far-infrared radiation component included in the second condensate obtained in the following may be lowered, and thus the alkali level may be decreased by using, for example, acid.

For example, referring to FIG. 2, in an example, in the step of lowering alkali (S1500), an acid may be added to lower the alkali of the mixture of the first condensate and water. The type of acid to be added may be variously used, such as hydrochloric acid (HCl) and acetic acid, but it may be preferable to use an organic acid such as acetic acid in terms of utilization of the liquid composition prepared in the present invention.

For example, in one example, the mixing ratio of the first condensate and water in the step of lowering the alkali (S1500) may be in the range of 1: 1.5 to 3 weight ratio. For example, the acid may be added after mixing so that the weight ratio of the first condensate and water is about 3: 7 or so.

For example, an organic acid may be used as an acid added to lower the alkali level. At this time, the pH of the first condensate mixture may be lowered to a range of 10 to 11.5 using an acid. For example, the pH of the first condensate mixture may be lowered in the range of 10.5 to 11.5, for example, within the range of 11.

Liquid composition acquisition step (S700, S1700, S2700)

Referring to Figures 1 to 4, in the liquid composition obtaining step (S700, S1700, S2700), a mixture having lowered alkali is heated and reacted at low pressure using a catalyst to obtain a liquid composition as a second condensate.

For example, referring to FIG. 2, in one example, a platinum or alumina catalyst may be used as a catalyst in the liquid composition obtaining step (S1700).

In addition, in the liquid composition obtaining step (S1700), a second condensate may be obtained by heating at a temperature of 120 to 180° C. at a pressure of 0.3 to 0.7 kgf/cm ² and performing a catalytic reaction.

Referring to FIG. 3, in one example, the liquid composition obtained in the liquid composition obtaining step (S2700) may include a silicon compound and a silicon oxide ion having far-infrared radiation.

At this time, for example, referring to FIG. 3, the silicate ion may include SiO ₃ ^- . In addition, the silicon compound may include any one or more of SiO-H, SiO ₄ and SiC-R, and R may be an alkyl group.

In addition, in one example, the obtained liquid composition may have a weight ratio of SiO ₂ to H ₂ O components in the range of 0.2 to 5: 99.8 to 95 on MSDS component analysis. It may be a weight ratio of about 0.8 to 2: 99.2 to 98, for example, about 1: 99.

Next, referring to FIG. 4, in an example, the method for preparing a liquid composition emitting far infrared rays may further include a washing or washing/sterilizing process (S50) before the first high-pressure heating step (S100). That is, the bran mixed with water in the step of firstly heating at high pressure (S100) undergoes washing or washing and sterilization (S50).

At this time, washing may be performed with an aqueous sodium chloride solution, and sterilization may be performed by UV treatment.

In addition, the bran mixed with water may be a powder of either rice husk or rice bran, or a mixture of both.

Test of far-infrared radiation liquid composition

For example, since it contains a silicon compound containing at least one of SiO-H, SiO ₄ and SiC-R, a silicon compound containing a silicon oxide ion containing SiO ₃ ^- , it exhibits a far-infrared radiation effect. R is an alkyl group.

The far-infrared radiation effect and components of the liquid formulation containing silicate ions and silicon compounds were investigated through tests. The results of measuring the far-infrared radiation energy of various products made using liquid formulations are as follows.
