The present invention removes suspended solids (SS; Suspended solid) in water by sand filtration (sand filter), micro filtration, ultra filtration, etc. Demineralized water from which salts were removed by filtration and reverse osmosis (RO filter) was partially subdivided by partial cleavage of hydrogen bonds in the water molecules (Micro 集); The present invention relates to a method for producing a tea beverage by subjecting the extract extracted from tea components to water treated with clustered water, subjecting it to electrolytic reduction, diluting with small group water, and then adjusting the pH, filtration and sterilization. .

Considering the following points in the manufacture of tea beverages:

Dried tea leaves contain about 30 wt% of catechins (Epicatechin, Gallocatechin, Epigallocatechin, Epicatechin gallate, Epigallocatechin gallate, etc.) and flavonol-type polyphenols. There is a problem that the precipitate is generated by the following reaction to degrade the quality of the product.

Polyphenolic compounds contained in tea are oxidized to quinone compounds by catalysis of polyphenoloxidase in aqueous solutions with high dissolved oxygen (DO) concentrations. A substance (protein, amino acid, etc.) and the following polycondensation reaction generate | occur | produce the precipitate which is insoluble in water.

Polyphenol Compound + O ₂ --Polyphenoloxidase → Quinone Compound + H ₂ O ₂ … … ①

Quinone Compound + Organics ----- → Cotton precipitate insoluble in water ... … … … … ②

The reaction of ① and ② described above is caused by the same mechanism as the mechanism of formation of corrosive substances due to the inflow of fluids of plants and plants in the natural ecosystem. Since the reaction deteriorates the quality of the product, the tea beverage should be manufactured considering the following points to prevent the reaction of ① and ②.

1) If the dissolved oxygen concentration in water is high, the reaction of ① is promoted, so the dissolved oxygen concentration in the water should be less than 1mg / l.

2) Because polyphenoloxidase is weak to heat, it is necessary to thoroughly inactivate the oxidase by heat treatment such as tea treatment or roasting.

3) Injecting enzymes with hemicellulase activity, enzymes such as lysolecithin, β-mannanase, and α-amylase to reduce oxidase activity It is possible to produce a clarified tea drink (있으나 料), but there is a problem in reducing the flavor (香味) when injecting excessive.

4) Reducing the oxidation reduction potential (ORP) value through the addition of reducing materials such as L-ascorbic acid or sodium ascorbate or by electrolytic reduction. Is preferably maintained.

5) When using raw water with high hardness, the extraction difference is inferior in extraction efficiency and the color is not clear, but the flavor is inferior, and it is insoluble by reacting with minerals such as calcium (Ca), magnesium (Mg) and iron (Fe) in water. A precipitate of can be produced.

Polyphenols (eg tannin) + minerals (eg iron) → polyphenolmineral salts (eg tannin)... ③

Calcium (Ca), iron (Fe), magnesium (Mg) in water; Raw water with high minerals (Minerals), such as polyphenolic mineral salts are insoluble in water can be produced because the precipitate can be used water of hardness less than 50mg / ℓ.

6) Polyphenol compounds such as tannins can react with compounds such as caffeine to form insoluble precipitates in water at low temperatures (when cooling).

Tannin + Caffeine --------------------------- → Sediment… … … … … … … … … ④

7) Water with too low pH thins the color of the extraction tea. Alkaline water with high pH decreases the aroma of tea.

8) Extraction temperature and extraction time of difference should be proper.

When the extraction temperature of tea liquor is below 50 ℃, the extraction efficiency decreases, and when it exceeds 90 ℃, the tannin component is excessively extracted and the bitter or tea taste is reduced. It is preferable to extract the extraction temperature at 50 to 90 ° C. for 2 to 15 minutes because the tannin component is excessively extracted and the bitter or tea taste is reduced even if it is long.

9) It should be used water in which odorous substance is not dissolved.

10) Microclusterted water with a small cluster of water molecules is good.

Small group water with small group of water molecules improves the extraction efficiency of tea liquor by improving penetration and dissolving power as surface tension decreases, and improves tea taste with excellent refreshing feeling.

Thus, in the present invention, a small group number in which the nuclear magnetic resonance ¹⁷ O-NMR value is in the range of 48 to 60 Hz is used.

In the measurement of the water molecule population, 1/10 of the ¹⁷ O-NMR value means the number of water molecules, and the number of water groups having ¹⁷ O-NMR value of 60 Hz is 6, and as in tap water, ^{17 The} number of groups of water molecules having an O-NMR value of 130 to 150 Hz is that of 13 to 15 water molecules forming aggregates by mutual hydrogen bonding.

In addition, the hydrogen bonds of the water molecules are partially broken, so that the small group number having a nuclear magnetic resonance ¹⁷ O-NMR value of 48 to 60 Hz is obtained. It has the following features.

① Small group water can improve the permeability as the surface tension decreases and the extraction power of tea components is improved, so that tea drinks with good color and aroma can be produced even with a small vehicle.

② improves the refreshment and improves the taste of water.

③ promote the body's absorption, excretion, and smooth blood flow to promote metabolism (新陳代謝).

④ Excellent antioxidant activity because of low Oxidation Reduction Potential (ORP).

The method of producing small groups with partial cut-off of hydrogen bonds of water molecules and having low ¹⁷ O-NMR value of nuclear magnetic resonance, treatment by constant voltage conductive tube applying low frequency low voltage low current, electromagnet or Magnetization by permanent magnet, electrostatic induction treatment, electrostatic treatment by DC high voltage, electrolysis treatment, high voltage high frequency discharge flame treatment, minus ion treatment, far infrared treatment, ultrasonic treatment, Mineralization treatment, high-speed impact treatment, high pressure treatment.

Among the above-mentioned small grouping treatments of water molecules, physical treatment such as treatment by constant voltage conductive tube, magnetization treatment by magnet, electrostatic induction treatment, electrostatic treatment by DC high voltage, far infrared treatment, ultrasonic treatment, high-speed impact treatment, and high pressure treatment The method has a high instantaneous treatment efficiency but has a characteristic of returning to the original water state of bound water as time passes, and the chemical treatment method by dissolving mineral components has low treatment efficiency but In addition, since there is a characteristic of long-term preservation by small groups of water, the small grouping treatment method of water molecules can be preserved for a long time while improving the treatment efficiency by treating two or more treatment methods in combination rather than treating with any single method.

In the manufacture of most green tea beverages, other than Korean Patent Registration No. 10-0195624, Japanese Patent Publication No. 2003-169603, and Japanese Patent Publication No. 2003-259806, the use of mineral water or general water with large aggregates of water molecules (Taste of water) has a problem of falling, and in the case of Korean Patent Registration No. 10-0195624, the green tea extract is left to cool for about 50 ° C. or less for a long time to induce the reaction of the aforementioned ① and ② to obtain a planar precipitate. Once produced, the method of preparing the green tea beverage after removing the precipitate may have a problem of degrading the quality of the product because the reaction of ① and ② described above may occur during distribution.

And hemicellulase activity as in Japanese Patent Application Laid-Open No. 8-228684, Patent Publication 2001-45973, Patent Publication 2001-204386, Patent Publication 2002-119209 and Patent Publication 2004-187613. Addition of enzymes such as α-amylase, lysolecithin, β-mannanase, or hydroxycarboxylic acid impairs the aroma and taste of green tea There is a problem.

In addition, Japanese Patent Publication Nos. 2002-272372 and 2002-34525 provide tea beverage preparation methods using demineralized water from deep sea water, but tea beverage preparation with dilute tap water and mineral water in demineralized water from deep sea water without measures to remove boron. There is a problem that can not take full advantage of the deep sea water characteristics, and the fermented green tea and its manufacturing method using the deep sea water of Japanese Patent Publication No. 2003-88343 also has no hygienic problem, so there is no hygienic problem of water molecules Since measures against small grouping and redox potential are not considered at all, there is a problem in that it is not possible to manufacture a healthy tea drink while improving the refreshing feeling.

In order to solve the above problems, the present invention extracts tea components by using demineralized water from which salinity is removed from deep ocean water and subpopulated water treated with 5 to 6 small groups of water molecules, followed by cooling and dehydration. It is an object of the present invention to provide a method for producing a tea beverage in which electrolytic reduction treatment is performed to have a good taste (cool feeling) and no precipitate is produced.

In order to achieve the above object, the present invention is to take the deep sea water of 200m or less depth and warm it to 20 ~ 30 ℃, and then filtered to produce demineralized water, small group of water molecules, extraction of tea components It is characterized by consisting of the step of preparing a tea drink.

Tea is largely divided into unfermented tea, semifermented tea and fermented tea according to the manufacturing method.

Unfermented tea is green, which leaves the leaves by heating with steam or heat to stop the activity of enzymes and prevents oxidation, and green tea is typical. Bucho tea (釜 炒 茶; cauldron) was roasted by the heat of the cauldron.

Semi-fermented tea is tea leaves exposed to the sun and dried in the shade to oxidize a part of the ingredients. When the aroma (풍 香) is poured into the cauldron, roasted oolong tea is typical.

Fermented tea is a leaf tea withered and rubbed well so that the leaves are sufficiently oxidized.

The manufacturing method of the tank which inactivates tea tree oxidase by steaming is as follows.

1. Steaming and Cooling Process

The steaming loses the activity of Oxidase in the green leaves, removes the green leaves, maintains green color, generates the inherent flavor of green tea, and improves the tea leaf's flexibility. In order to facilitate dry operation, saturated water vapor close to 100 ° C is brought into contact with the tea leaves for 20 to 40 seconds, and then cooled to 35 ° C ± 2 by a cooling fan.

This is because when the temperature of the tea leaves rises from 37 ℃ the color turns black.

The heating time should be shorter as the leaves are younger, and when the deep green tea is made to improve the color of the green tea and reduce the astringent taste, it is long, and the quenching improves the luster of the tea leaves.

The steamed tea leaves are dried and heated to 45-60wt% while stirring and kneading for 35-45 minutes in a hot air at 95-100 ℃ in an oil tank, and the characteristic color and flavor of green tea are developed. It is a process to make the moisture of each part uniform and to make efficient drying. The quality of the tea is mostly determined in this process, so the work should be well done.

In this process, the drying process is to pressurize the tea leaves and leach the moisture inside to the surface of the tea leaves so that the entire leaf surface is covered with a thin film of moisture, and then apply a constant hot air to increase the moisture on the tea leaf surface. Maintain the temperature of tea leaves at 35 ℃ ± 1 to remove moisture without changing chlorophyll.

Keep in mind that the process speeds up per minute while applying high pressure to the tea leaves at room temperature for 10 to 20 minutes at room temperature in order to equalize the moisture content of each part of the tea leaves and to destroy cell tissues appropriately so that the tea components can easily be formed and improve their shape. It is a process to repeat pressing and rubbing (note) by rotating about 100-140 times.

Depending on the tea leaf, the pressure and rotation speed should be different. If the caution is excessive, the tea crumbs will be more bitter and the bitter taste will be strong. If the caution is insufficient, the shape will become large and the color and color of the leaching liquor will be red. It tastes good.

The heavy oil process removes moisture from the tea leaves in mind and makes tea suitable for the next refinery process.The tea leaves are stirred and pressed under hot air at 55-65 ℃ for 20-30 minutes in a heavy oil machine. In the process of balancing the diffusion of moisture on the surface of tea leaves and internal moisture, the moisture content is dried up to 26 to 30 wt%, and the rate drying occurs until the middle stage of the process. Therefore, the temperature of the tea or the exhaust temperature rises, so when the tea leaves are removed, the temperature rises to around 36 ° C.

The oil refining process is a final finishing process of forming and drying by applying heat from the bottom while applying heavy pressure to the tea leaves. The oil refining process is dried up to 25% by weight in 40 minutes.

6. Drying Process

In the drying process, if the moisture content is high during maintenance, it is difficult to maintain the quality, so the drying process is performed with hot air of 70 ° C. or less so that the moisture content is 5wt% or less.

It is dried to sieve dry tea (water) with a water content of 5wt% or less, or it is put into a cutting machine to produce a car (煎 茶).

In the cauldron, the manufacturing method of Bucho tea roasted with heat without water is as follows.

1. Squeeze process

In the quenching process, the oxidase of tea leaves is heated to a temperature of around 380 ℃ in the cauldron, and is deactivated by quenching and deactivating. If the heat treatment temperature is too high, the tea leaves burn. Temperature rise is important because temperature rises and becomes red.

2. Mindful Process

The process of equalizing the water content of the tea leaves and destroying the tea tree tissues to make them look good and shape. The degree of rubbing depends on the leaves, but the young leaves are light and the hard leaves are heavy.

3. Primary drying process

It is a process to make flavors, and it is made by direct heating to have the unique flavor of tea.

4. Second drying process

It is a process of making bent tea leaves, and it forms a shape by drying through rotation to make a unique shape of tea.

5. Final drying process

In the drying process, if the moisture content is high during maintenance, it is difficult to maintain the quality, so it is dried so that the moisture content is 5 wt% or less.

As described above, green tea is inactivated by steaming the tea leaves with steam, and then dried chariot (전) and roasted with heat in a cauldron without water to inactivate enzymes (덖초), in the present invention any one tea It is not limited to.

In addition, the following considerations should be taken into consideration for the production of high quality tea beverages using deep sea water.

1. The boron compound should be treated with the drinking water standard below 0.3mg / l.

Deep sea water contains 4 to 5 mg / l of boron and is present in the form of boric acid (H ₃ BO ₃ ), and has a small particle size of about 0.23 0.2, so nanofiltration and reverse osmosis are used to treat drinking water. Since it is difficult to process below the standard value of 0.3mg / l, the pH is adjusted to 9 ~ 11, and the boric acid is converted to polyboric acid in the gel state to reverse osmosis filtration. To deal with.

When boric acid in water is subjected to alkali treatment, it is converted to polyboric acid in gel state by the following reaction.

B (OH) ₃ + OH ^_ → [B (OH) ₄ ] ^- → [B ₃ O ₃ (OH) ₄ ] ^- → [B ₄ O ₅ (OH) ₄ ] ^2- → [B ₅ O ₆ (OH ) ₄ ] ^- … ⑤

2. Hardness should be less than 50mg / ℓ of water.

If the hardness of water is used, the extraction difference is less effective in extraction and the color is not clear, but the flavor is inferior and the insoluble precipitate reacts with minerals such as calcium (Ca), magnesium (Mg) and iron (Fe) in water. Water of hardness greater than 100 mg / l should not be used as this may be produced.

3. Adjust the Oxidation Reduction Potential (ORP) value within the range of +100 to -200 mA.

Water with redox potential of less than + 200㎷ is called reducing water, and reducing water has the ability to eliminate free radicals in the body, which is good for health, and when the redox potential is below -200㎷, it tastes like tea. In order to reduce, in the present invention, the redox potential value is adjusted in the range of +100 to -200 mA.

The redox potential of deep sea water is slightly lower (+165 to +175 kPa) compared to +500 to +700 kPa for general beverages such as tap water, but higher than the appropriate value of +100 to -200 kPa.

4. Nuclear Magnetic Resonance (NMR) ¹⁷ O-NMR values are treated in the range of 48 to 60 Hz.

5. The pH of the extraction difference is 4.5-5.5 weakly acidic water.

Hereinafter, the contents of the present invention will be described in detail with reference to the drawings.

In FIG. 1, the deep ocean water is taken from the seabed below 200 m.
I. Taking deep sea water of 200m or less in depth and warming it to 20 ~ 30 ℃, then filtering to produce demineralized water

The intake method is to take down the pipe below 200m from the ship's bottom, or to install the pipe up to 200m below the sea level, or to collect it with a pump, or to install the pipe up to the sea level below 200m below the sea level. Water is taken in accordance with the siphon principle.

The deep sea water collected in the sump is warmed to 20 to 30 ° C because of its low viscosity (0 to 10 ° C) and high filtration efficiency.

The warming method may be supplied with heat from a boiler, or may use sea surface water in the summer.

The warmed deep sea water is filtered through sand filtration, micro filtration, ultra filtration alone or a combination of the two, followed by nano filtration and reverse osmosis filtration. Pretreatment is performed to remove suspended solids (SS) in the osmosis filter (SS) so that fouling does not occur as much as possible.

At this time, the filtration pressure is determined in consideration of the pressure loss of the filter and the pressure loss of the pipe according to the operating conditions.The filtration speed of sand filtration is 6-10 m / hour, and the effective diameter of the filter sand is 0.3-0.45 mm, the uniformity coefficient shall be 2.0 or less, and the thickness of the filtrate layer shall be 0.5-1.0 m.

Microfiltration and ultrafiltration are independent of the type of filtration membrane, and the supply pressure is determined in consideration of the filtration rate and the pressure loss according to the specifications of the vendor.

The deep seawater from which suspended solids are removed from the pre-filtration process is sent to the first pH adjustment process to generate scales in the nanofiltration membrane and the reverse osmosis filtration membrane so that the pH can be suppressed as much as possible. At pH 6.5, hydrochloric acid (HCl) is used in inorganic acids.

The pH adjustment method is to adjust the pH to 5.5 to 6.5 while injecting the pH adjuster into the pre-filtered deep sea water while stirring the stirring time (retention time) for 15 to 30 minutes with a propeller agitator of 180 to 360 RPM (rotational speed). To the nanofiltration process.

The membrane modules of the nano filter and reverse osmosis filter used are tubular, hollow fiber, and spiral. It does not matter in any form, such as spiral wound or plate and frame, and the material of the membrane is not particularly limited.

Nano filter is a solution of CaCO ₃ and CaSO ₄ dissolved in deep ocean water. As the solubility is small, the scale is formed in the membrane during the concentration of the salt in the reverse osmosis filtration process, so that the pH is adjusted from 5.5 to 6.5 in the first pH adjustment process in order to minimize the fouling phenomenon. The mineral acid, such as CaCO ₃ , CaSO ₄ , MgCl ₂ , MgSO ₄ , is removed by 90% by weight.

The pressure supplied to the nanofiltration process is 15 to 25 atm, and in the case of spiral wound type, the membrane permeation amount is 0.7 to 1.4 m 3 / m 2 · day.

In the nanofiltration process, concentrated mineral water concentrated with minerals such as CaCO ₃ , CaSO ₄ , MgCl ₂ and MgSO ₄ is sent to the decontamination process along with the concentrated brine discharged from the brine concentrated reverse osmosis process, and the filtered demineralized water is 1 It is sent to the reverse osmosis filtration process.

The operating pressure of the first reverse osmosis filtration process is supplied to the filtration membrane at 50 to 60 atmospheres (atm), and in the case of the spiral filtration membrane, the salt permeate is removed when the membrane permeate is operated at 0.5 to 0.8 m 3 / m 2 · day.

Demineralized desalted water is sent to the secondary pH adjustment process, and brine is sent to the brine concentrated reverse osmosis process.

The brine supplied to the brine concentrated reverse osmosis process is supplied to the filtration membrane with an operating pressure of 80 to 120 atm (atm) .In the case of the spiral filtration membrane, the membrane permeate is operated at 0.7 to 0.8㎥ / ㎡ The desalted water, which is dehydrated, is returned to the first pH adjustment process.

The primary demineralized water supplied to the secondary pH adjustment process supplies one of NaOH, NaHCO ₃ and Na ₂ CO ₃ as an alkali (Alkali) to convert the unremoved boric acid to polyboric acid. The range is adjusted and sent to the second reverse osmosis filtration process.

Operation conditions of the 2nd pH adjustment process As in the 1st pH adjustment process, pH adjustment method is a 1st reverse osmosis process, stirring the stirring time (retention time) with a propeller stirrer of 180-360 RPM (rotational speed) for 15 to 30 minutes. The pH is adjusted to 9-11 while injecting demineralized water and a pH adjuster.

When the pH is adjusted to 9 ~ 11 in the secondary pH adjustment process and supplied to the secondary reverse osmosis filtration process, the operating pressure is supplied to the filtration membrane at 10-20 atm, and in the case of the spiral filtration membrane, the membrane permeate amount is 0.6 to 0.8. Demineralized water filtered by boron concentration below 0.3mg / ℓ, which is operated at ㎥ / ㎡ · day, is sent to the small grouping process of water molecules, and unfiltered brine is drained to the original position below 200m after neutralization treatment. (Eject).

In the second reverse osmosis process, even if the pH is supplied in an alkaline state of 9 to ₁₁ , scale generation is not a problem since the nanofiltration process removes materials such as CaCO ₃ and CaSO ₄ that produce scale.
II. Small grouping of water molecules

When demineralized water demineralized in the second reverse osmosis filtration process flows into the electronic treatment tank 1 of the small grouping process of water molecules, a high-pressure alternating-current constant voltage is transferred from an electrostatic charger 7 to the electrode 2. When a voltage of 3,000 to 5,000 Volt (field strength of 0.3 to 15 KV / m) and a current of 0.4 to 1.6 μA are applied for 4 hours or more, the positive and negative electrostatic fields are alternately repeated around the electrode 2 to form water molecules. When the water molecules themselves are vibrated and rotated repeatedly, the hydrogen bonds of the water molecules are partially broken, and the water molecules are sent to the intermediate treatment water storage tank 8, and the constant voltage conductors are transferred to the intermediate treatment water transfer pump 9. After the magnetization treatment by applying alternating current or direct current low voltage of 0.5 to 5V to the coil wound to the conductive tube and wound on the conductive tube, ¹⁷ O-NM of Nuclear Magnetic Resonance When the measured value of R is produced in microclustered water in the range of 48 to 60 Hz, the remainder is sent to the small-group water treatment tank (11), and the third pH adjustment process and extraction are carried out by the small-group water transfer pump (12). Send to the difference dilution process.

The flow rate sent from the intermediate treatment water storage tank (8) to the intermediate treatment water transfer pump (9) to the constant voltage conductive tube magnetizer (10) and returned to the electronic treatment tank (1) is 1 to 1 of the inflow flow rate (second reverse osmosis process demineralized water). 4 times.

As such, the water in which the population of water molecules is sub-populated is treated with reduced energy having a high alkaline oxidation frequency and high energy redox potential of +100 to -200 mV.

The applied voltage of the constant voltage generator 7 is adjusted in accordance with the values of pHI and ORPI installed in the intermediate treatment water storage tank 8.

The material of the electrolytic treatment tank 1 is made of stainless steel, and a stainless steel electrode filled with charcoal or activated carbon having high conductivity therein (2) ), The lower part of the insulator (3) polyethylene (polyethylene), polyvinyl chloride (PVC), styrofoam (Styrofoam) is selected and installed, the lower part of the insulator (3) is a conductor and corrosion-resistant material A stainless steel sheet 4 is installed between the foundation concrete structures 5, and the stainless steel sheet 4 is grounded 6 to the ground.

The constant voltage conductor magnetizer 10 is in the range of 0.5 to 5 V in a coil wound around a cylindrical conductive tube of insulating material such as synthetic resin (PVC, PE, styrene resin, etc.), ebonite, FRP, and Bakelite. When a low voltage of alternating current or direct current is applied, a magnetic field is formed inside the coil, and when water passes through it, the water is treated as a small group water.

If the capacity of the treated water is large, the electronic treatment tank 1 in which the mesh of the stainless steel electrode 2 filled with charcoal or activated carbon is installed in multiple stages is installed. Process.

In the case of seabed rocks (also referred to as seawater, 海洋 深層 巖 盤 水 or 海底 深層 化石 海水), excavated less than 200m of rock in the island or coastal areas, the seawater penetrates into the rock or soil. Although there are some differences depending on the characteristics of the rock and soil, the Na ⁺ ions are mainly replaced with the Ca in the rock or soil, so the Na ⁺ ions are slightly decreased, and the Ca ^{2 +} ions are increased. In the above-described deep ocean water treatment process, subpopulated water may be produced using subsea rock water instead of deep ocean water.

In case of producing small group water by taking in deep sea bedrock, there is a possibility that the contaminated sea surface water flows into the well. Therefore, the piping of the well should be installed up to 200m below the seabed, so that the inlet well should not be installed. .

The small group water treated in the small grouping process of the above-mentioned water molecules is sent to the extraction difference dilution process, and some of them are sent to the third pH adjustment process.
III. Steps to Extract Tea Ingredients

The small group water flowed into the 3rd pH adjustment process was supplied with 5-20 wt% of ascorbic acid aqueous solution as organic acid, adjusted to pH 4.5-5.5, and then sent to the heating process to supply heat from the boiler. The hot water heated to 50 ~ 90 ℃ is sent to the difference extraction process.

In the tea liquid extraction process, 25-35 kg of hot water is injected per 1m 3 (tons) of hot water, tea components are extracted for 2 to 15 minutes with stirring for 1 to 10 times, followed by a filtering process. It removes the declination while passing sequentially through 10-30 mesh and 100-200 mesh filters.

The decanted tea extract is sent to a cooling process (preferably a plate heat exchanger), cooled to 10 to 20 ° C, and then sent to a centrifuge rotating at 3,000 to 10,000 rpm to dehydrate the solids. The silver is sent to the electrolytic reduction treatment process cathode chamber 22, and the oxidation reduction potential (ORP) is adjusted to a range of +100 to -200 mV and sent to the extraction difference dilution process.

The electrolytic cell 20 of the electrolytic reduction treatment process is isolated between the anode chamber 21 and the cathode chamber 22 by a diaphragm 20, and the anode 23 of the anode chamber 21 is highly corroded. Corrosion resistance titanium plate (TiO ₂ ) and ruthenium (Ruthenium) (RuO ₂ ) coated (DSA) electrode using a coating (Dimally stable anode), the cathode 24 is hydrogen generation Iron, titanium, nickel with high overvoltage. An electrode coated with an active nickel of Raney nickel on a metal plate, and the like, the diaphragm uses a cation exchange membrane that passes only cations without passing anions, and the electrolytic cell 20 is a corrosion resistant material. You just need

In the operation of the electrolytic reduction process, a voltage of 3 to 20 V from the rectifier is applied to the positive electrode 23 and the negative electrode 24 so that the value of ORPI (Oxidation Reduction Potential Indicator) of the negative electrode chamber 22 is in the range of +100 to -200 mA. the present invention because there is a fear that be incorporated in the tea beverages ^- the application (印加), and one using a NaCl aqueous solution with water has generally the electrolyte to be supplied to the anode chamber 21 is detrimental free residual chlorine in the human body (HClO, CLO) In the water flowing into the anode chamber 21, the NaOH aqueous solution of 5-20 wt% is in the range of 10-300 mg / l (NaOH injection concentration is the applied voltage in the rectifier, ORPI value of the cathode chamber 22, anode chamber (21) according to the value of pHI) while supplying to the cathode chamber 22, an extraction difference liquid, which is a dehydration filtrate discharged from the centrifugal dehydration process, is supplied with an extraction reduction liquid having a redox potential value in the range of +100 to -200 kPa. To prepare and send to the step of preparing a tea drink.
Ⅳ. Steps to manufacture tea drinks

In the electrolytic reduction process, the extraction difference, which is the difference reduction water with the redox potential adjusted to the range of +100 to -200 mV, is sent to the extraction difference dilution process to transfer the small group water of the small group storage tank to the extraction difference. Dilute by 3-5 times infusion.

The tea beverage diluted with the extracted tea solution was adjusted to pH range of 5.8-8.5 by adding sodium hydrogen carbonate (NaHCO ₃ ) aqueous solution and sent to the microfiltration process, followed by microfiltration with 0.5-5μ (micron) filter cloth. After processing, they are sent to a tea beverage reservoir for storage.

At this time, if the ultrafiltration treatment is performed as in the filtration of drinking water, it is preferable not to perform too high filtration because it can reduce the quality of the product by filtering a considerable amount of tea components.

Microfiltered tea beverages are subjected to high-temperature sterilization or UV sterilization at 120-135 ℃ for 0.5-10 minutes, then sent to the container filling process and filled into containers (cans or plastic bottles). Ship it.

As described above, in the present invention, the deep ocean water has an infinite amount, and contains various minerals useful for cleanliness and human body, and the value of ¹⁷ O-NMR of nuclear magnetic resonance under high water pressure for many years. Because of the characteristic that the population of water molecules is aged from 7 to 8 at 75 to 80 Hz, the tea is extracted with water treated with salt and boron within the drinking water standard. Long-term preservation is expected to have a widely used effect in the production of tea drinks because no precipitate is produced.
