The present invention relates to a method for producing a beverage, and more particularly, to a method for producing a beverage by taking the rock water from the underground bedrock and sequentially treating the sand filtration process, activated carbon filtration process, electrolysis process, sterilization process. .

For tap water, the value of nuclear magnetic resonance ¹⁷ O-NMR half-width ranges from 130 to 150㎐, while the rock water discharged from the mining area of Gonamsan magnetized magnetite mine in Pocheon-myeon, Pocheon-si, Korea, meets the drinking water standard. Nuclear Magnetic Resonance ¹⁷ O-NMR half-width is around 90㎐ and water taste is much better than tap water or general mineral water.

The water molecules form clusters by mutual hydrogen bonding, and the measurement of the number of these water molecules is carried out using the nuclear magnetic resonance ¹⁷ O-NMR half-width. Indirect measurement by value reveals that 1/10 of the value of the ¹⁷ O-NMR half-width is indicated by the number of populations of water molecules. Like tap water, about 13 to 15 molecules of water have a population of water with a value of 130-150 kPa of ¹⁷ O-NMR half width.

In general, drinking water is in the situation of using tap water or wells, and in case of tap water, there is a problem in which harmful substances such as free chlorine and THM (Trihalomethanes) are contained, and in the case of wells, bacteria and There is a problem that various harmful substances can be contaminated.

In addition, most of these waters are chlorine disinfection, and the oxidation-reduction potential (ORP) value of +500 kPa or more is an oxidizing beverage having a problem that is not good for health.

The hydrogen has a redox potential (ORP) of -420 kW and the oxygen reduction potential (ORP) of oxygen is +815 kW, the water having a median of +200 kW or less is called reduced water. Is called oxidized water.

The present invention has an object of the present invention to provide a method for producing a reducing beverage that is hygienic and safe and healthy by taking mineral water in order to solve the above problems.

In order to achieve the above object, the present invention provides a process for collecting mineral water from mines or magnetites that generate magnetized magnetite and anions, sand filtration process, activated carbon filtration process, precision filtration process, sterilization process, and container filling. It is characterized by a process, an inspection and a packaging process.

The present invention is a method for producing a beverage in which mineral water is taken from an underground rock, sand filtration, activated carbon filtration, precision filtration, sterilization, container filling, and inspection and packaging are sequentially performed. When described in detail by the drawings as follows.

1. The process of taking mineral water from underground rock

In the intake zone in the present invention, intake of mineral water from the underground rock in an area where the value of the Nuclear magnetic resonance (NMR) ¹⁷ O-NMR half-width of the magnetite ore is 90 kPa or less. In the excavation of the ball, the alluvial layer is installed with an outer casing with a diameter of 250 to 300 mmφ, and then excavated to a solid rock line to secure an inner casing with a diameter of 200 to 300 mmφ. Excavate at least 100mmφ larger than outer casing bore to secure grouting thickness.

Grouting is a reverse-circulating pressure cement grouting from the bottom of the lens top to the space between the casing and the lens to prevent the inflow of contaminated water from the top after the end of the upper section. In this case, grouting is performed until the injection back to the surface, and the grouting injection agent uses a cement mixture containing 2-4 vol% of bentonite.

After the grouting is completely solidified, excavate to the lower aquifer with a diameter of 150 ~ 250mmφ, and then verify the grouting construction, casing installation, aquifer, etc. Install a pump and install a meter and protection device that can automatically measure the amount of water intake.

In addition, water wells are equipped with monitoring wells and continuous automatic measuring devices (water level, electrical intensity, temperature, pH, etc.).

The water collected from the intake well is transferred to the raw water storage tank, and the raw water storage tank is two or more tanks, and a sealed lid is installed and a sterilizer and an air filter are installed.

2. Sand filtration process

The water stored in the raw water reservoir is sent to a sand-filled filtration tower to remove suspended solids (SS) from the water.

The sand packed in the filtration tower has an effective size of 0.45 to 0.7 mm, a uniformity coefficient of 1.7 or less, a maximum diameter of not more than 2.0 mm, and a minimum diameter of 0.3 mm or less. In this case, the maximum diameter and the minimum diameter are 1% or less.

The filtration tower performs either rapid filtration or slow filtration and selects one of the two depending on the amount of solids in the water.In the case of rapid filtration, the filtration speed is designed to be 120 ~ 200m / day and the thickness of the filtrate is 60 ~ 70㎝. In the case of rapid filtration, the filtration rate is 4-5 m / day and the thickness of the filtrate is 70-90 cm.

If the concentration of organic matter in raw water is more than 3mg / l of COD _Mn , sand filtration is followed by activated carbon filtration.

And the concentration of the organic substance greater than the value of the COD _Mn 3㎎ / ℓ in the raw water is followed by removal of the solid matter in the water in that sand filtration process are sent to the microfiltration step.

3. Activated Carbon Filtration Process

If organic matter is present in the raw water, the water from which the solid matter is removed from sand filtration is sent to the activated carbon packed column of activated carbon filtration to remove the organic matter from the water and then sent to the microfiltration process.

The activated carbon packed column is designed to have a linear speed of 4 to 10 m / hour and a residence time of at least 1 hour.

4. Precision filtration process

In the microfiltration process, one type of ultrafiltration or micro-filtration is selected and the FI (Fouling index) value of water is treated in the range of 2 to 4 and sent to the electrolysis process.

However, when the oxidation-reduction potential (ORP) value of raw water is less than + 200㎷, microfiltration water is sent to the sterilization process.

The FI value is a numerical value representing the fine turbidity concentration in the target water and is expressed by the following equation.

FI = (1-T ₀ / T ₁₅ ) x 100/15... … … … … … … … … … ①

Where T ₀ is the time required for filtration of the first 500 mL of sample water when the sample water was filtered under pressure of 0.2 MPa using a 0.45 μm microfiltration membrane, and T ₁₅ was filtered for 15 minutes in the same state as T _0. After that, it is time required for filtration of 500 ml of sample water.

Is sent to the alkaline reduced water storage tank (8), and then sent to the sterilization process by the alkaline reduced water transfer pump (9).

The anode chamber water supplied to the anode chamber 2 is a pH indicating switch (pHIS), and the anode chamber water is adjusted by adjusting the solenoid valve (ⓢ) at the inflow side so that the pH is in the range of 1.5 to 3.0. At this time, the redox potential value displayed on the oxidation reduction potential indicator (ORPI) generates electrolytic oxidation water in the range of +850 to +1,100 ㎷.
