The present invention discloses functional grains comprising rice coated with gold as aged and ultra-fine as described above.

Nano (120) coated grains made of ultrafine particles of gold according to the above constitution are excellent in antiseptic function and digestion function when put into the human body, and the decoration of the grains before cooking and the long-term preservation and the extension of the preservation period and the taste change after cooking There is little effect of prolonging the shelf life in moisture, surrounding pollutants and long-term distribution.

The present invention generally relates to dry coating by attaching a gold (gold) target 200 having a purity of 50 to 99.999% to a plasma dry coating apparatus on a surface of a body such as grains representatively of rice used as a staple food in the Asian region.

On the other hand, rice has been a staple food of our ancestors, forming the basis of our diet, and forming our food culture. Since the 1980s, we have achieved self-sufficiency of grain, and in 2001 we produced 3830 million seats. However, while supply continues to increase, demand is decreasing every year. Per capita consumption, which peaked at 136.4 kg in 1970, declined to 119.6 kg in the 1990s and 93.6 kg in 2000, and rapidly declined to 88.9 kg in 2001. It was. This decrease in rice consumption is a major cause of staple foods, such as hamburgers, pizza, pork cutlet, and chicken, which are eaten mainly by young people as the dietary lifestyle has become western, and obesity and high blood pressure can be attributed to high calories and effects. It can also be a culprit.

As such, the decrease in consumption led to an increase in inventory due to the increase in supply, and the stock increased from 457 million seats in 1995 to 5.55 million seats in 1998, 749 million seats in 2000, and 9.89 million seats in 2001 and 13.3 million seats in 2002. In 2005, 18 million seats were reached in 2005, when inventories exceeded 20 million seats.

This increase in inventories not only entails huge administrative costs but also burdens supply and demand, leading to a drop in rice prices, which in turn leads to a decrease in farm household income. In addition to the decline in rice prices due to the increase in production, in addition to the UR negotiations and the endless competition of the WTO open economy, quality improvement for farmers' survival and continuous development, production cost reduction, and promotion of rice consumption through the development of various processed foods, etc. The government's support through various strategies is urgently needed.

In particular, in order to survive domestic farmers and related companies in the fully opened rice market in 2006, differentiation from imported rice is required, and development of functional grains is emerging as a differentiation method. The emergence of functional grains, on the other hand, has shifted from an interest in rice as a staple to a quantity of “quality” to an age of “full stomach” eating and a “healthy” eating wellbeing with regard to health. Recently, organic rice, seaweed rice, kelp rice, green tea rice, jade rice, diabetic rice, ionic rice, radish rice, DHA rice, flavor rice, ginseng rice, chitosan rice, etc. The development of various functional rice, such as germanium rice, Ganoderma lucidum culture rice, and Cordyceps sinensis rice, has been continuously made by local governments and farmers 'organizations and sold to the market. Recently, consumers' attention has been focused on functional rice.

Functional rice is a rice that has a specific effect on the ordinary rice or by adding a special substance to give a specific effect, it is an advanced than non-pesticide rice or organic rice and requires a high level of technical skills.

The present invention relates to gold nano 120 coating 140 of the body surface of cereals, such as barley, beans, red beans, crude, sesame seeds, wheat, corn, including rice, as described above.

Au has traditionally made acupuncture in Chinese medicine to cure malignant swelling,

Blood bottle with powdered medicine. It was used to treat bronchial asthma and various diseases. Before antibiotic anti-inflammatory drugs appeared, Au was used to treat pulmonary tuberculosis.

Ring made of gold (Au). necklace. The reason you want to put earrings on your body is because it is a precious metal and has a better effect on the treatment of arthritis than its value.

The effect of gold (Au) in Dongbobom or herbaceous wood is even and tasteful, without poison, Jinsin, Anh and White, sincerity, five jang, It is written that it is conservative, treats the long span of the five intestines and the actual symptoms, and heals the child's game. "Diva Situanake, of Birmingham City Hospital, UK." X-rays of 30 patients with arthritis wearing gold rings and 25 non-rings showed that the ring joint He reported that arthritis was significantly less than the same finger on his hand.

The gold ring next to the finger also showed less damage to the joints, and the treatment of injecting gold (Au) into patients with rheumatoid arthritis began in the 1940s and was already approved by the US Food and Drug Administration.

Gold (Au 金, gold) is a copper group element belonging to group 1B of the periodic table, the element symbol Au, atomic number 79, atomic weight 196.967 melting point 1064 ℃ boiling point 2966 ℃, specific gravity 19.3 (20 ℃) This is a representative precious metal,

Au is primarily a self-help or electrum (alloy of natural gold and natural gold), which is produced in the quartz vein together with pyrite, galena and tungsten minerals. Combined with, it is produced in the quartz vein as a tellurium gold or in other metal ores such as copper, lead, and zinc. It is also produced as fine natural gold. I)

The largest natural gold found so far was found in Victoria, Australia, in 1869 and weighed 2,520 ounces.

On the other hand, what is calculated from the weathered residual deposits derived from acid gold

It is called placer. The number of Clarks is 5 × 10-7, the amount of which is extremely small, and the world's major gold producers are South Africa, Russia, and the United States. Among them, about 40% of the world's total output is produced in the Transval region of South Africa. It is mainly produced from Gubong Mine in Cheongyang-gun, Chungnam.

The hardness of Au is 2.5 to 3, and the malleability and ductility are very large and normal.

The thickness of gold leaf is 0.00001cm, 1g of gold can draw 3,000m of gold thread, and the color of pure gold varies depending on its condition. The lump of yellow color is yellow, but when powder or colloid becomes purple When it melts, it becomes green, and when it forms a vapor deposition film, it turns red. When it becomes thin foil, it becomes green to blue by transmitted light.

It is a good conductor of electricity and heat, the electrical conductivity is 67% of gold, and the specific resistance is 2.2 × 10 -6Ω, cm (18 ℃). The thermal conductivity is 0.708 cal / cm, sec, deg, 70% of the gold.

It does not change in air or water, does not change color, does not change with strong oxidizing agents, and does not dissolve in acids and bases, but it dissolves in aqua regia to form geum chloride. When oxygen is present, it dissolves in an aqueous solution of alkali cyanide salt, forming cyano succinate, and does not react with oxygen and sulfur even at high temperatures, but directly bonds with chlorine and bromine. In the compounds, the oxidation number is usually monovalent or trivalent.

Next, the method of manufacturing gold varies depending on the calculation state and other situations, but generally, the method of collecting gold varies depending on place of gold and gold.

In the case of placer, there are urine method, urine method and gutter method that use a large amount of gold. In the case of the urine law and swelling (含 金 砂 泥) in the water and then shaken from front to back, left and right light soils are removed and heavy gold (Au) is left at the bottom of the bowl.

In the gutter method, dozens of gutters, 40 cm deep, 30 cm deep, and 40 m long, are connected to each other by pouring water into the gutters and adding alloy sand into the water to remove light soil and leave heavy gold in certain areas.

In the case of acid gold, the Hon Hong method and cyanization method are used. In the Hong Hong method, gold is used to make mercury and amalgam well. When mercury is evaporated from amalgam, only gold is left.

That is, the ore is first pulverized in water and then flowed over the surface of the copper plate formed with amalgam with mercury to collect the light malt formed on the copper plate, and then distilled with iron retort to remove mercury.

The extraction rate of gold is 60 to 80%, the rest is reprocessed by cyanation, etc., and the cyanation method uses a property that an aqueous solution of sodium cyanide can dissolve gold in the presence of air.

    2Au + 4NaCN + O + H2O → 2Na Au (CN) 2 + 2Na OH

The liquid in which gold is dissolved is called ear fluid, and zinc is added to this solution.

    2Na Au (CN) 2 + Zn → Na 2Zn (CN) 2 + 2Au

The gold is extracted by, and it is rare to use the halo and cyanide methods alone, respectively.

Drying is a method used in copper and lead dry smelters where silica ore is required as a flux in copper and lead smelting. Instead, gold ore is used as a byproduct.

 Next, look at the purification of gold is as follows.

 The subsidiary pension and the dry method contain silver and other substances, so the acid-dividing method and electrolytic method are used to separate them. Dissolving silver with sulfuric acid and leaving only gold,

The electrolytic method is a method in which a little is cast into a plate to make an anode, and gold is deposited on a pure gold plate of a cathode using gold chloride as an electrolyte.

Electrolysis is performed by keeping the temperature of the liquid at 60 ~ 70 ℃, and when the content of gold is small, only DC is used. However, in many cases, the silver chloride film on the anode surface is removed by alternating DC and AC, and the deposited gold is a graphite crucible. It is melted in the inside, and the purity is 99.99%.

 It was already discovered by other scientists in 1999 that the gold (Au) becomes a gold (Au) catalyst that promotes the reaction very effectively when it is reduced to nanometer (nm, 1m / m) levels. Adsorption of these gold molecules (gold octimers) onto a magnesium metal oxide with surface defects results in an electrical charge in which electrons from the magnesium surface defects transfer to the gold catalyst. It has been found to weaken and break and promote new binding reactions. This principle has been confirmed through simulations of quantum mechanics and vibration frequency measurements of reactant molecules.

Nano-size gold grains are also used as secondary transducers, and are dispersed evenly in a solution to make use of the properties of gold nanoparticles (120), which change color when they are agglomerated. It can also be used to check.

First, a gold grain is prepared by attaching a complementary DNA strand to one end of a specific portion of anthrax DNA, and then a gold grain is attached to the opposite end of the anthrax DNA. When these two kinds of gold grains are put into a solution, they are mixed with each other and present in an evenly dispersed form. When a sample containing anthrax DNA enters, the anthrax DNA connects two kinds of DNA strands attached to the gold grains.

As a result, the gold grains agglomerate and change color to detect the presence of anthrax. In this case, the DNA attached to the gold grain acts as a primary transducer, and when aggregated, the nano-gold grains representing the color change are secondary transducers. Play a role.

  As described above, the manufacturing method of gold nano 120 is currently released in a wide variety of ways, and good methods are being developed and developed one after another. A conventional method of preparing gold or gold nano 120 powder is a gas phase manufacturing method, a liquid phase. It can be divided into the manufacturing method and the mechanical manufacturing method used, and there are also the gas condensation method and the gas phase reduction method, and the mechanical grinding method using the mechanical force.

The uniformity of the particle size of the prepared powder is good and can produce particles of high purity, and the advantages and disadvantages of preventing the agglomeration of the particles have the disadvantage that the experimental equipment is expensive.

In addition, the manufacturing method using the liquid phase is capable of producing a uniform powder than the manufacturing method using the gas phase, and also has the advantage of manufacturing the powder at a low device cost, but the tendency of aggregation of the individual particles is very strong and the shape of the particles is somewhat irregular The disadvantage is that.

Next, there is a mechanical manufacturing method, there is a problem in the incorporation of impurities generated in the manufacturing process and the disadvantages of aggregating phenomenon is severe, while there is an advantage that can easily mix various components.

In the present invention, the gold target 200 having a purity of 50 to 99.999% on the surface of the body is attached to the plasma dry coating apparatus to dry-coated to make the grain 100 having antimicrobial power and decorativeness.

Next, briefly explaining the drawing of the grain 100 coated with the gold nano120 of the present invention 140 to achieve the above object as follows.

 Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be briefly described.

Figure 1 shows a conventional rice and rice in the present invention as a photograph showing a photograph of the rice before milling and the rice after milling.

In order to manufacture the gold nano 120 coated rice, rice is composed of rice husk layer, rice bran layer, embryo and pear flow path before the milling, and the rice bran layer and embryo are removed from the brown rice by removing rice husk layer with brown rice. Removing is called a milling. Milling is a complex process of several stages, and general milling consists of raw material (rice) → fine selection → encapsulation (separation) → brown rice separation → sedimentation → white color → wet tailing → granulation separation → color selection → product washing. Rice is made through the process.

5 is a dry coating block diagram of the gold nano-coated grains of the present invention coating all grains 140 of any one selected from grains such as rice, barley, beans, red beans, crude, corn, wheat 140 Looking at the sputtering, deposition, thin film of the plasma coating method 140 of the dry plating of the grain 100 of the present invention as follows.

Plasma is a gaseous state that is separated into electrons with positive charges and positively charged ions at high temperatures, and has a high degree of charge separation, but is neutral due to the same number of positive and positive charges.

 Since the long-acting Coulomb force acts between charges, it has the characteristic of the whole group moving together under the influence of the distant state rather than the local state of the short distance. In 1928, I. Langmuer, USA, first applied the concept of plasma to ionized gases produced during electrical discharges.

  Plasma is derived from the Greek words πλσμα, -ατos, τ and its original meaning is that it is built and assembled, and as the characteristics of collective behavior suggest, it actually deals with plasma. There is a view that Plasma itself is usually behaving arbitrarily rather than easily controlled from the outside, and that the original name is wrong.So, Plasma is used as the fourth one after solid, liquid and gas (three states of matter). It is called material state.

As the temperature gradually increases, almost all objects change from solid to liquid and gaseous state, and at tens of thousands of degrees Celsius, the gas is separated into electrons and atomic nuclei into plasma.

Each object that forms a plasma is electric, so it is very different from the neutral gas, has a high electrical conductivity, and is limited to the surface like a metal conductor. When applied, it is easily affected by the force as a charge, but as the charge density increases, the group movement differs from the individual movement, and the self-closing required by nuclear fusion means that the charge follows the magnetic field line. It is used to confine the plasma to it by deforming the magnetic field lines appropriately and confining them to a place in space.

 In the past, plasma research has been conducted in geophysics and astrophysics in relation to the plasma around the earth and celestial bodies, but in recent years, the development of electromagnetic fluid dynamics (MHD) using the electrical properties of plasma, the long-distance travel rocket engine Research is underway for research on fusion and nuclear fusion, and it has been a long time since the Department of Plasma was established in the science and engineering field of Korean universities.

 As such, the high temperature and active chemical properties of plasma can be used to provide extreme environments that are difficult to obtain by conventional methods and to give physical and chemical properties different from the body by changing the properties of new materials, metals or polymers. there is,

Diamond, for example, is an important material not only for jewelry but also for industry because of its high hardness, thermal conductivity, refractive index, and large band gap. Artificial synthesis of diamond was developed by GE company in USA in the 1950s. Although a high temperature and high pressure method has been mainly used, it was found in the early 80s that diamonds could be obtained in the form of a thin film at low pressure from methane gas plasma in the USSR, thereby coating semiconductor devices, tool coatings 140, optical parts, and medical device coatings. New fields of application are being actively explored.

In addition, the wear-resistant coating of the tool, the decorative coating, it can be made by the dry method through the reactive ion plating, sputtering, thin film method used as a diffusion barrier at the contact point in the manufacture of semiconductor devices.

In addition, if the surface of the polymer is treated with nitrogen or oxygen plasma (Plasma), it can give hydrophilicity or hydrophobicity to the surface of the polymer, or it can improve the antistatic, dichroic, deep color, etc. In contact with the plasma and applying a bias, a nitride or carbide layer is formed on the surface to improve the hardness, wear resistance, and corrosion resistance of the metal.

Some of the effects that can be obtained by the surface coating 140 and the reforming technique using plasma can be obtained by the conventional wet plating or coating 140 method, but considering the environmental pollution problem, dryness using plasma can be achieved. The method has many advantages, and it is possible to apply plasma to plasma welding, cutting, processing of materials using high temperature of plasma and to spray plasma, and to dissolve high melting point powder into plasma By coating 140 on it will significantly increase the heat resistance, corrosion resistance, wear resistance and the like.

 In addition, it is possible to manufacture ultra-fine particles and quench the synthesized particles by using the high temperature and high activity of the thermal plasma (Plasma) synthesized into the ultra-fine particles to plasma or chemically or physically deposited plasma to produce a functional film using the plasma (Plasma) By using the high temperature, high activity of the thermal plasma has the advantage that can be decomposed and vitrified waste.

As such, the plasma coating 140 operates the vacuum pump 300 to operate the vacuum pump 300 to evacuate 320 to completely discharge the air in the chamber through the vacuum discharge port 260, and to generate argon and other inert gases 420. When the electrical discharge is generated after the injection, the gas introduced into the chamber 160 is ionized. At this time, the ionized gas collides with the injected gold target and the gold 120 atoms protrude into the particle state. (100)) to the coating 140 is to be able to control the thickness in nano units significantly according to the plating time.

The deposition principle is the operation of the vacuum pump 300 to collect a high output laser light to the deposition material (target) located in the chamber (chamber) in the vacuum 160 state, the pulse is the deposition material gold nano 120 The temperature of the grains 100 is raised sharply, so that explosive vaporization, that is, melting occurs, on the surface.

When the holder 400 of grains containing the coating body is placed close to the deposition target 200, the sputtered material is blown onto the substrate to be uniformly deposited, and the remaining film is heated to a temperature higher than the deposition temperature of the low temperature deposition step and the low temperature deposition step. It is also desirable to use a two-step deposition method that includes a high temperature deposition step for depositing and the laser deposition method.

A first step of first depositing nano-sized particles and a thick gold film on the surface of the grains of the present invention after inputting the dried grains 460 washed with water after removal of the 480 from the first deposition conditions; And a gold target 200 having a purity of 50 to 99.999% and a coating body including a second step of depositing a second coating layer on the first deposited gold film under a deposition condition changed to be different from the first deposition condition. Placing the grain into the chamber 160;

Providing a gold target (200) and said target (200) arranged to face away from said target (200) to supply at least one inert or reactive gas (420) in a plasma apparatus into said plasma apparatus;

Supplying a power source (220) to the plasma device;

Depositing a gold film on a surface of the grains at a temperature of 20 to 200 ° C. by a function of a nano size thickness; And increasing the temperature of the chamber 160 to 40 to 200 ° C. after the deposition step, and depositing the coating 140 to a thickness of 0.001 to 1000 μm (micro) on the surface of the primary grains.

Introducing an inert gas 420 into the chamber 160; Attached is a rotating body 440 which rotates the holder 100 holding the grain 100 for effective coating of the grain 100 around the grain 100 and the holder 400 and an axis perpendicular to the surface of the grain. To discharge the air in the chamber completely through the vacuum discharge port 260 inside the chamber 160 for sputtering with the grain holder 400 and the chamber 160, and inert gas 420 is discharged. A gas inlet port 260 for introducing into the burr 160;

A target (200) for emitting gold particles by sputtering set in the chamber (160); The grain 100 is preferably installed perpendicular to the direction emitted from the target 200 by the plasma.

In the plasma sputtering of the present invention, the vacuum chamber 160 is used to generate ions by the gold target 200, and the gold particles generated in the chamber 160 cause the grains of the grain 100 to be formed. A thin film or a thick film is formed on the surface. First, an inert gas 420 such as argon (Ar) is used to generate gold coated particles, and the gold targets 200 and grains 100 as source materials are placed on opposite parallel plates connected to a high voltage power source. First, the chamber 160 discharges air in the chamber through the vacuum discharge port 260 by the operation of the vacuum pump 300 to make a vacuum 320 and then flows a low pressure sputtering gas into the chamber 160. .

 When the electrode is energized, argon gas (Ar +) is ionized and gold (Au) ions are generated between the plates, and the plate covered with the source material is maintained at a negative potential, so that the argon ions are accelerated to the plate covered with the source material. In the impact of argon ions, source atoms and molecules are released from the plate and fly to the surface of the grain 100 to be deposited.

 On the other hand, in the vacuum 320 of 0.001 to 0.01 Torr in the inert (mainly argon) chamber 160, a high voltage of several hundred volts is applied between the electrodes to cause an abnormal discharge, thereby causing the inert ions to collide with the gold target 200 to convert the momentum. The gold target 200 material is scattered by the gas scattered to reach the body surface of the grain 100 of the grain holder of the rotary holder 400 containing the grain is a highly integrated coagulation method using gas ions.

The diameter of the gold target 200 is, for example, 200 mm, the distance between the gold target 200 and the grain 100 and the holder 400 is, for example, 200 mm, and the area where most of the particles are emitted is the area of the target 200. It is preferable to be located near the rear side of the target 200 so as to be an area having a diameter of 100 mm.

In the sputtering apparatus configured as described above, the distance between the gold target 200 as the source material and the grain 100 is longer than the diameter of the general sputtering technique, and the sputtering is performed at a low pressure, so that the particles can be sputtered with an inert gas ( It is possible to directly reach the grain 100, which is a coating, without being dispersed by the particles of 420.

On the other hand, in the circumferential portion of the grain 100, the number of particles discharged from the circumferential region of the target 200 by sputtering is smaller than the particles emitted from the central portion of the target 200 will be aging.

Thus, in the through hole 360 formed in the silicon oxide film 340, the Ti film formed on the inner wall surface is closer to the circumferential portion of the grain 100 than the thickness at the portion closer to the center of the grain 100. The part will have a thicker thickness.

 The grain 100 is oriented in the direction in which the surface of the grain most particles are released from the gold target 200 by sputtering, the line perpendicular to the grain 100 can almost pass through the center of the target 200 In such a way, the fluid grain holder 400, which is the rotating body 440, is attached to the chamber 160 to be completely coated to a blind spot where gold ions do not reach. The rotary holder 400 is preferably rotated in combination for smooth coating, such as one-way, two-way, reverse rotation, asymmetrical rotation.

Inert gas 420 for sputtering is then introduced into chamber 160 and as a result, the mean free path of molecules of sputtering gas is longer than the distance between the center of gold target 200 and grain 100, In the state where the grain 100 can be rotated around an axis perpendicular to the surface of the grain, the gold particles are released from the target 200 by sputtering.

The direction in which most of the particles are released from the target 200 by sputtering is most preferably a direction perpendicular to the surface of the target 200.

In the plasma of the present invention, when high-energy particles collide with the surface of a solid, atoms of the gold nano120 target material 200 are exerted out of the surface by exchanging momentum by the full elastic collision.

Applying a negative voltage to the target in the vacuum 320 and inserting an inert gas 420 including argon (Ar), helium, and nitrogen gas to apply a voltage to the glow discharge occurs

And the sputtering is to be promoted by applying a magnetic field to the target 200 side.

When the ion collides with the kinetic energy larger than the binding energy between atoms of the material, the ion bombardment pushes the atoms between the lattice to different positions.

The phenomenon of surface escape of atoms is called sputtering in physics.

In addition, sputtering in thin film deposition can be regarded as a concept including two processes of release of a target atom and attachment of the atom to a substrate, and a sputtering process. The best feature of is that almost all materials can be used as targets because the movement of the deposited material into the gas phase is not a chemical or thermal process but a physical momentum exchange process. This is an advantage of plasma coating.

This plasma phenomenon is used to form a gold or gold nano 120 particle film on the surface of the grain or ion-beam, electron-beam or radio-frequency laser sputtering It is also preferable to coat the gold nano 120 coating 140 of the grains of the present invention using sputtering.

 The use of the laser has advantages such as higher quality, simplicity and reproducibility, and the biggest advantage is that the vacuum 320 is not necessarily required unlike other methods, and liquid or gaseous deposition materials can be used. There is an advantage that the equipment installation is expensive and high temperature may occur, the grains can be burned easily.
