Description

  The present invention relates to a method for producing hydrogen-containing water suitable for beverages.

  Reduced water whose oxidation-reduction potential has a negative value can remove active oxygen in the body, which is the cause of aging and disease, allergic diseases such as pollinosis, atopy and asthma, digestive system diseases such as gastrointestinal tract, and It has been reported that health problems such as hypertension can also be improved.

  Since hydrogen has a strong reducing power, the reducibility can be enhanced by adding hydrogen to well water or tap water.

  The hydrogen-containing water for drinking can be produced by, for example, aeration of hydrogen gas in raw material water. However, since hydrogen gas is almost dissolved in water at atmospheric pressure, conventionally, hydrogen gas is contained in a raw material water in a pressure vessel in a sealed state while being pressurized.

  For example, in Patent Document 1 below, hydrogen gas is filled in a pressure vessel from which air has been removed, and the pressure vessel contains minerals while maintaining the pressure of the hydrogen gas at 2 to 10 atm. The raw water is sprinkled in a shower form and brought into contact with hydrogen gas, so that the hydrogen gas in the pressure vessel is dissolved in the raw water, then it is filled in a highly airtight container and sealed, and heated in that state. It is disclosed that hydrogen-containing water is produced by sterilization treatment.

  That is, Patent Document 1 describes a technique in which hydrogen gas is dissolved in raw water under pressure, sealed in a highly airtight container, and heat-sterilized in that state to obtain potable hydrogen-reduced water. It also describes that when mineral (metal) is contained in the raw water, the oxidation-reduction potential can be shifted, the raw water is desalted, and the mineral is added to the raw water.

  In Patent Document 2 below, the liquid chamber and the gas chamber are partitioned by a gas permeable membrane made of a hydrophobic hollow fiber membrane, water is introduced into the liquid chamber and discharged, and hydrogen gas is introduced into the gas chamber. A technique for discharging and obtaining hydrogen-dissolved water is described.

  Furthermore, Patent Document 3 below describes a technique for obtaining a favorite beverage by dissolving hydrogen gas (and an inert gas) in deoxygenated water through a permeable membrane having a hollow fiber structure and adding a concentrated raw material. .

  Patent Document 4 below describes a technique for obtaining reduced water by dissolving hydrogen gas in alkaline reduced water prepared by an electrolysis method.

  Patent Document 5 below describes a technique for obtaining drinking water containing a large amount of hydrogen by dissolving hydrogen obtained by electrolyzing water in water through a porous membrane. Is an invention with a completely different purpose.

JP 2005-296794 A (Patent No. 3606466) JP 2000-51606 A JP 2001-86963 A JP 2004-230370 A JP 2002-172317 A

However, the prior art described in the above literature has room for improvement in the following points.
First, since the technology of Patent Document 1 and Patent Document 4 (Examples 3 and 4) is a batch type, the productivity is poor, and a large-scale manufacturing apparatus is required to produce a large amount of hydrogen-containing water. There was a problem. In addition, hydrogen cannot be efficiently dissolved in the raw water, resulting in a problem that not only the consumption of hydrogen increases but also the hydrogen concentration tends to vary from lot to lot. This is because when hydrogen-containing water is produced in a batch mode, when the hydrogen-containing water is extracted from the pressurized tank and filled in a highly airtight container and sealed, dissolved hydrogen can easily escape, This is because oxygen (or air) was easily mixed.

  As described above, in the batch type, it is assumed that there are various factors as the factors in which dissolved hydrogen is easily removed during extraction and filling, and oxygen (or air) in the filling atmosphere is likely to be mixed. However, it is assumed that one of the major factors is that the fluid pressure is greatly reduced by Bernoulli's theorem during extraction and filling. That is, when extracting the dissolved hydrogen water from a pressure vessel such as a pressurized tank, the dissolved hydrogen water is usually extracted through a pipe-shaped extraction pipe having a diameter much smaller than the tank diameter of the pressurized tank. Therefore, according to Bernoulli's theorem, which will be described later, the pressure applied to the dissolved hydrogen water as a fluid is greatly reduced as compared with that in the pressurized tank.

  In addition, in the batch system, dissolved hydrogen can easily escape during extraction and filling, and another major factor that can easily cause oxygen (or air) in the filling atmosphere to enter is the pressure in pressurized tanks, etc. When extracting the dissolved hydrogen water from the container, the upper part of the pressurized tank is usually released into the atmosphere or the factory atmosphere, or a replacement gas for extruding the dissolved hydrogen water into the space above the pressurized tank ( Usually, it is necessary to introduce air).

  If this is not done, negative pressure will be generated during the extraction and filling of the dissolved hydrogen water at the upper part of the sealed pressurized tank except for the extraction part, and the extraction and filling of the dissolved hydrogen water will be smooth. Becomes difficult. If this is not done, oxygen (or air) in the filling atmosphere from the gap between the filler filling port and the opening of the highly airtight container to the inside of the pipe-shaped extraction pipe Backflow tends to occur. Therefore, in the end, either the upper part of the pressurized tank is released into the atmosphere or the factory atmosphere, or a replacement gas (usually air) for pushing out the dissolved hydrogen water into the space above the pressurized tank. Become. As a result, in the batch type, hydrogen in the dissolved hydrogen easily escapes from the upper part of the pressurized tank during extraction / filling, and oxygen (or air) in the atmosphere or factory atmosphere tends to be mixed. .

  As a result, in the batch method, even if hydrogen gas is dissolved in raw water under pressure, even if a high dissolved hydrogen concentration can be achieved, the removal of hydrogen and oxygen during subsequent extraction and filling Further improvement in that the concentration of hydrogen in the dissolved hydrogen water that is sealed inside the highly airtight container will greatly decrease compared to the dissolved hydrogen concentration that can be achieved in the pressurized tank. There was room for.

  Secondly, in the techniques of Patent Document 2, Patent Document 3 and Patent Document 4 (Examples 1 and 2), hydrogen gas is dissolved in the raw water in a continuous manner, but the dissolved hydrogen concentration in the dissolved hydrogen water is continuously increased. In the process, the flow cell sensor is not used for online measurement. Instead, the dissolved hydrogen concentration (DH) or redox potential (ORP) of the degassed sample water flowing out from the continuous process is offline. It is measured by. However, in such offline measurement, operating conditions (changes in factory atmosphere due to season, time, weather, etc.), raw water (changes in quality of tap water and natural water due to season, time, weather, etc.), raw gas (gas There is room for further improvement in that the hydrogen concentration tends to vary from lot to lot of dissolved hydrogen water obtained in this continuous process due to variations in conditions such as variations in the lots of supply sources).

  Thirdly, in the techniques of Patent Document 1 and Patent Document 4, it is assumed that a high dissolved hydrogen concentration can be realized. However, in actuality, the dissolved hydrogen concentration is not directly measured, but merely a redox potential (ORP). It is only measuring. As will be described later, the oxidation-reduction potential (ORP) is an index that varies greatly even under the same dissolved hydrogen concentration depending on various conditions such as pH, and the dissolved hydrogen concentration in the dissolved hydrogen water. It is not appropriate as an index to evaluate Therefore, in the techniques of Patent Document 1 and Patent Document 4, there is room for further improvement in terms of the demonstrability of a high dissolved hydrogen concentration.

  The present invention has been made in view of the above circumstances, and provides a method for producing hydrogen-containing water for drinking that is suitable for mass production, has little variation in hydrogen concentration, and has a high hydrogen concentration, which is difficult to achieve with a batch method. It is in.

  According to the present invention, there is provided a method for producing hydrogen-containing water for beverages, wherein the raw water is divided into a raw water circulation part and a hydrogen gas circulation part by a gas permeable membrane made of a hydrophobic material. A step of supplying the raw material water circulation part, a step of supplying pressurized hydrogen gas to the hydrogen gas circulation part of the hydrogen gas dissolving module to dissolve hydrogen in the raw water, and the raw water of the hydrogen gas dissolving module Filling and sealing the container with hydrogen-containing water in which hydrogen gas discharged from the circulation part is dissolved, sterilizing the hydrogen-containing water filled and sealed in the container, and the concentration of dissolved hydrogen in the hydrogen-containing water In the hydrogen gas circulation section of the hydrogen gas dissolution module so that the dissolved hydrogen concentration in the hydrogen-containing water falls within a predetermined range based on the on-line measurement process and the on-line measurement result. And a step of controlling the dissolution pressure of hydrogen gas, a method is provided.

  In addition, in this method, hydrogen-containing water is produced in a continuous process, not a batch process, and is filled and sealed. There is no such a tendency that oxygen (or air) in the atmosphere or factory atmosphere is easily mixed. As a result, in this method, in addition to being able to achieve a high dissolved hydrogen concentration in a state where hydrogen gas is dissolved in the raw water by the hydrogen gas dissolution module, hydrogen escape and oxygen (air) during subsequent extraction and filling Therefore, the hydrogen concentration in the dissolved hydrogen water sealed inside the highly airtight container can be maintained as high as the dissolved hydrogen concentration realized in the hydrogen gas dissolution module.

  In this method, the hydrogen content in the dissolved hydrogen water is measured as the dissolved hydrogen concentration (DH). Therefore, as will be described later, the concentration of dissolved hydrogen in dissolved hydrogen water is not greatly changed depending on various conditions such as pH, as often occurs when measured as an oxidation-reduction potential (ORP). The hydrogen content in the dissolved hydrogen water can be evaluated by an appropriate index as an index to be evaluated.

  Furthermore, in this method, hydrogen gas is dissolved in the raw water in a continuous manner, and the hydrogen content in the dissolved hydrogen water is further determined online by using a flow cell sensor etc. Hydrogen gas in the hydrogen gas circulation section of the hydrogen gas dissolution module is measured as a concentration (DH), and the dissolved hydrogen concentration in the hydrogen-containing water is within a predetermined range based on the on-line measurement result. So-called negative feedback control is performed to control the dissolution pressure.

  Therefore, operating conditions (changes in factory atmosphere due to season, time, weather, etc.), raw water (changes in quality of tap water and natural water due to season, time, weather, etc.), raw material gas (for each gas supply lot) Even if there are variations in conditions such as (variation), these variations are alleviated by the negative feedback control described above, and variation in the hydrogen concentration for each lot of dissolved hydrogen water obtained in this continuous process is suppressed.

Thus, according to this method, hydrogen can be efficiently contained in the raw water in a short time, so that stable quality hydrogen-containing water for drinking can be produced with high productivity.

  Further, according to the present invention, there is provided a hydrogen-containing water production apparatus for beverages, a hydrogen gas dissolution module partitioned into a raw water circulation part and a hydrogen gas circulation part by a gas permeable membrane made of a hydrophobic material, and a raw material A raw material water supply unit that supplies water to a raw material water circulation part of a hydrogen gas dissolution module partitioned into a raw material water circulation part and a hydrogen gas circulation part by a gas permeable membrane made of a hydrophobic material, and the hydrogen gas dissolution module A hydrogen gas supply part that supplies pressurized hydrogen gas to the hydrogen gas circulation part, and a filling / sealing that fills the container with hydrogen-containing water in which hydrogen gas discharged from the raw water circulation part of the hydrogen gas dissolution module is dissolved. A sealed part, a sterilizing part for sterilizing the hydrogen-containing water sealed in the container, a hydrogen concentration measuring part for measuring the dissolved hydrogen concentration in the hydrogen-containing water online, and an online measurement result And a pressure control unit for controlling the dissolution pressure of the hydrogen gas in the hydrogen gas circulation unit of the hydrogen gas dissolution module so that the dissolved hydrogen concentration in the hydrogen-containing water is within a predetermined range. Is done.

  According to this apparatus, for the same reason as in the description of the method described above, hydrogen can be efficiently contained in the raw water in a short time. Therefore, stable hydrogen-containing water for drinking can be produced with high productivity. Can be manufactured.

  According to the present invention, stable hydrogen-containing water for drinking can be produced with high productivity.

<Embodiment 1>
One Embodiment of the manufacturing apparatus of the hydrogen containing water for drinks which can be used for the manufacturing method of the hydrogen containing water for drinks of this invention is described using FIG. This manufacturing apparatus 20 is mainly composed of an activated carbon tank 1, a membrane filtration device 2, a deaeration device 3, a hydrogen gas dissolution module 4, a UV / UHT sterilization device 5, and a filling device 6. .

  In the activated carbon tank 1, the raw water supplied into the tank is dechlorinated. A pipe L <b> 1 extending from an external source water source is connected upstream of the activated carbon tank 1. A pipe L <b> 2 extends from the downstream of the activated carbon tank 1 and is connected to the membrane filtration device 2.

  In the membrane filtration device 2, the raw water dechlorinated in the activated carbon tank 1 (hereinafter referred to as “dechlorinated water”) is filtered. As the filtration membrane used in the membrane filtration device 2, a nanofilter (NF membrane) is preferably used, but an RO membrane can also be used. A pipe L3 extends from the downstream side of the membrane filtration device 2 and is connected to the deaeration device 3. Further, the pipe L3 is connected to a pipe L4 that branches off in the middle and is connected to the electrolyzer 7.

  In the deaeration device 3, oxygen gas, nitrogen gas, carbon dioxide gas, etc. dissolved in the raw water filtered by the membrane filtration device 2 (hereinafter referred to as “filtered water”) are removed. Examples of the deaerator 3 include a vacuum deaerator and a membrane deaerator using a gas permeable membrane. A pipe L5 extends from the downstream side of the deaerator 3 and is connected to a raw material water circulation part 4a of the hydrogen gas dissolution module 4 described later.

  In the electrolyzer 7, the filtered water is electrolyzed to generate hydrogen gas and oxygen gas. The inside of the electrolyzer 7 has a cathode chamber 7a, an anode chamber 7b, and an ion exchange membrane 7c, and electrolysis water (filtered raw material water) is supplied from the pipe L4 to the cathode chamber 7a and the anode chamber 7b. Is done. A pipe L6 extends from the cathode chamber 7a (hydrogen gas generation side) of the electrolyzer 7 and is connected to a hydrogen gas circulation part 4b of the hydrogen gas dissolution module 4 described later. A pipe L7 extends from the anode chamber 7b (oxygen gas generation side) of the electrolyzer 7 and is connected to an oxygen storage holder or the like.

  The hydrogen gas dissolution module 4 is partitioned into a raw material water circulation part 4a and a hydrogen gas circulation part 4b by a gas permeable membrane 4c made of a hydrophobic material. And the piping L5 mentioned above is connected to the raw material water distribution | circulation part 4a, and the piping L6 mentioned above is connected to the hydrogen gas distribution | circulation part 4b, respectively. A pipe L8 extends from the downstream of the raw material water circulation part 4a and is connected to the UV / UHT sterilizer 5. Further, a pipe L9 extends from the downstream side of the hydrogen gas circulation part 4b to discharge the hydrogen gas in the hydrogen gas circulation part 4b out of the system.

  The material of the gas permeable membrane 4c used in the hydrogen gas dissolution module 4 is not particularly limited as long as it has hydrophobicity, and is a silicon resin, an olefin resin such as polyethylene, polypropylene, or poly-4-methylpentene-1, Examples thereof include fluorine-based resins such as polyfluoroethylene. As a form of the gas permeable membrane 4c used for the hydrogen gas dissolution module 4, a hollow fiber membrane etc. are mentioned as an example.

  The manufacturing apparatus 20 further includes a flow cell sensor 101. This flow cell sensor 101 measures the content of hydrogen in dissolved hydrogen water obtained by dissolving hydrogen gas in raw water in a continuous manner, not as a redox potential (ORP) but as a dissolved hydrogen concentration (DH).

  The manufacturing apparatus 20 further includes a hydrogen gas pressure control unit 103. Based on the on-line measurement result by the flow cell sensor 101, the pressure control unit 103 adjusts the hydrogen gas in the hydrogen gas circulation unit of the hydrogen gas dissolution module so that the dissolved hydrogen concentration in the hydrogen-containing water is within a predetermined range. So-called negative feedback control is performed to control the melting pressure.

  FIG. 2 shows an example of a hydrogen gas dissolution module using a hollow fiber membrane as the gas permeable membrane 4c. In this hydrogen gas dissolution module, a hollow fiber membrane 42 made of a gas permeable membrane is disposed inside a container 41. The hollow fiber membrane 42 is formed with a raw water inlet 43 for introducing raw water into the hollow fiber membrane and a gas-dissolved water outlet 44 for discharging the water inside the hollow fiber to the outside. A pipe L5 is connected to the raw water inlet 43, and a pipe L8 extends from the gas-dissolved water outlet 44.

  Further, the container 41 is formed with a hydrogen gas inlet 45 for introducing hydrogen gas into the container 41 and a hydrogen gas outlet 46 for discharging the hydrogen gas out of the system. Is connected to a pipe L6, and a pipe L9 extends from the hydrogen gas outlet 46. The pipe L9 is provided with a valve 47 so that the pressure inside the container 41 becomes a predetermined pressure. This valve 47 may be anything as long as it can maintain gas such as an on-off valve, a pressure reducing valve, and a resistance in a pressurized state. By controlling the opening and closing of the valve 47, the pressure in the container 41 can be controlled to a predetermined value.

  That is, in FIG. 2, the inside of the hollow fiber membrane is the “raw water circulation part” of the present invention, and the space 48 inside the container 41 and outside the hollow fiber membrane is the “hydrogen gas circulation part” of the present invention. . In addition, although FIG. 2 has the structure which distribute | circulates raw material water inside a hollow fiber membrane, it distribute | circulates raw material water on the outer side of a hollow fiber membrane, and distribute | circulates hydrogen gas inside a hollow fiber membrane. Any configuration may be used.

  In the UV / UHT sterilizer 5, raw water (hereinafter referred to as “gas-dissolved water”) in which hydrogen gas is dissolved by the hydrogen gas-dissolving module 4 is irradiated with UV to kill germs and microorganisms, and UHT ( Ultra High Temperature (Ultra-high temperature) sterilization by sterilization method is also performed. A pipe L10 extends from the downstream of the UV / UHT sterilizer 5 and is connected to the filling device 6.

  In the filling device 6, the gas-dissolved water sterilized by the UV / UHT sterilization device 5 is filled in a sealed container, sealed, and sterilized.

Next, the case where the said manufacturing apparatus is used is demonstrated as an example about the manufacturing method of the hydrogen containing water for drinks of this invention.

  The raw material water that can be used in the method for producing hydrogen-containing water for beverages of the present invention is not particularly limited as long as it is water obtained from a water source suitable for beverages, and examples thereof include tap water and groundwater.

First, raw water is supplied from the pipe L1 to the activated carbon tank 1, activated carbon installed in the tank is brought into contact with the raw water, and chlorine or the like in the raw water is adsorbed on the activated carbon for dechlorination treatment. Next, the raw water (dechlorinated water) dechlorinated in the activated carbon tank 1 is supplied from the pipe L2 to the membrane filtration device 2 and filtered to remove suspended matters and the like.

  When a nanofilter is used as the filtration membrane, it is preferable to adjust the electric conductivity of dechlorinated water so as to be 5 to 2,000 μs / cm, and more preferably 100 to 1000 μs / cm. . When the electrical conductivity is less than 5 μs / cm, mineral components such as metal ions are hardly contained, so that it is unsuitable for beverages. Moreover, when it processes so that it may exceed 2,000 microseconds / cm, the organic substance removal by filtration processing may be inadequate, and a problem arises in a hygiene aspect.

  In addition, when an RO membrane is used as a filtration membrane, even metal ions in dechlorinated water are removed by the RO membrane due to the filtration treatment by the RO membrane. After performing, it is preferable to add metal ions suitable for beverages such as sodium ions and potassium ions, so that the electrical conductivity of the filtered water is adjusted to 5 to 2,000 μs / cm. More preferably, it is particularly preferable to prepare so as to be 100 to 1000 μs / cm. Alternatively, instead of adding metal ions, gas juice, vegetable extract, cacao extract, coffee extract, tea extract, gas dissolved water discharged from the raw material water circulation unit 4a of the hydrogen gas dissolving module 4 described later, One or more selected from herbal extracts, honey, sweeteners, and lactic acid bacteria may be added, thereby making it possible to produce hydrogen-containing water that is suitable for beverages and has high palatability.

  Next, dechlorinated water (filtered water) filtered by the membrane filtration device 2 is supplied to the deaeration device 3 from the pipe L3 and supplied to the electrolyzer 7 from the pipe L4.

  The filtered water (degasified water) supplied to the degassing device 3 from the pipe L3 is degassed here to remove oxygen gas, nitrogen gas, carbon dioxide gas, etc. dissolved in the filtered water. And it supplies to the raw material water distribution | circulation part 4a of the hydrogen gas melt | dissolution module 4 from the piping L5. The degassing treatment of the filtered water is preferably performed until the concentration of the gas dissolved in the filtered water reaches 10 ppm or less (particularly preferably DO <2 ppm). By performing the deaeration treatment, the hydrogen gas dissolution module 4 can easily dissolve a large amount of hydrogen gas in a short time, and can efficiently produce hydrogen-containing water for beverages having a high hydrogen gas concentration.

The filtered water supplied from the pipe L4 to the electrolyzer 7 is electrolyzed here into hydrogen gas and oxygen gas. Then, the hydrogen gas generated on the cathode chamber 7 a side of the electrolyzer 7 is supplied to the hydrogen gas circulation part 4 b of the hydrogen gas dissolution module 4, and the raw water flowing through the raw water circulation part 4 a of the hydrogen gas dissolution module 4 Dissolve in. The oxygen gas generated on the anode chamber 7b side of the electrolyzer 7 is extracted from the pipe L7 and supplied to an oxygen gas holder or the like.

  In the hydrogen gas dissolution module 4, degassed water is supplied from the pipe L5 to the raw water circulation part 4a, and hydrogen gas is supplied from the pipe L6 to the hydrogen gas circulation part 4b to pressurize the inside of the hydrogen gas circulation part 4b. By pressurizing the hydrogen gas circulation part 4b with hydrogen gas, due to the partial pressure difference, the hydrogen gas in the hydrogen gas circulation part 4b permeates the gas permeation membrane 4c and flows into the deaerated water flowing through the raw water circulation part 4a. Dissolve. Thus, in this invention, since degassed water melt | dissolves hydrogen gas when passing the raw material water distribution | circulation part 4a, hydrogen gas can be dissolved in deaerated water in a short time and in large quantities.

The pressure in the hydrogen gas circulation part 4b is not particularly limited as long as it is equal to or higher than atmospheric pressure, and is preferably 1 to 5 kgf / cm ³ . If it is less than 1 kgf / cm ³ , hydrogen gas may not be sufficiently dissolved in the deaerated water. On the other hand, if it exceeds 5 kgf / cm ³ , the pressure resistance and airtightness of various facilities of the hydrogen gas melting module must be increased, which is economically disadvantageous.

  At this time, in supplying the degassed water from the pipe L5 to the raw material water circulation part 4a, the hydrogen gas dissolving module 4 cools the degassed water (the raw water after degassing) in advance and then supplies the hydrogen gas dissolving module 4 It is preferable to supply to the raw material water circulation part 4a. For example, the temperature of the deaerated water after cooling is preferably 30 ° C. or lower, more preferably 20 ° C. or lower, and most preferably 10 ° C. or lower. However, in order to suppress freezing, the temperature is normally maintained at 0 ° C. or higher. As described above, by supplying the raw water circulation part 4a of the hydrogen gas dissolution module 4 after cooling the deaerated water in advance, the hydrogen gas is easily dissolved in the cooled deaerated water. This is because it can be increased.

  Next, in the hydrogen gas dissolution module 4, the raw water (gas dissolved water) in which hydrogen gas is dissolved is subjected to UV irradiation and UHT treatment in the UV / UHT sterilizer 5 to kill germs and microorganisms. Filter with an ultrafiltration membrane. And as needed, after adding 1 or more types chosen from fruit juice, vegetable extract, cacao extract, coffee extract, tea extract, herbal extract, honey, sweetener, and lactic acid bacteria, it is in filling apparatus 6 For example, bags filled with aluminum laminate film, metal cans, particularly preferably aluminum bags with spouts with suction cups, filled into various containers such as aluminum cans, sealed, and then sterilized to drink Hydrogen-containing water can be produced.

  In this embodiment, the flow cell sensor 101 provided immediately before the filling device 6 uses the hydrogen gas dissolution module 4 to determine the hydrogen content in the raw water (gas dissolved water) in which hydrogen gas is dissolved. , It is measured not as redox potential (ORP) but as dissolved hydrogen concentration (DH). Although it does not specifically limit as a dissolved hydrogen meter (hydrogen concentration measuring device), For example, a dissolved hydrogen meter (hydrogen concentration measuring device) Bionics Co., Ltd. BIH-50D etc. can be used suitably.

  FIG. 4 is a graph for explaining the relationship between the oxidation-reduction potential (ORP), the dissolved hydrogen concentration (DH), and the hydrogen ion concentration (pH). As shown in this graph, even if the dissolved hydrogen concentration (DH) is constant, if the hydrogen ion concentration (pH) changes, the redox potential (ORP) also changes. That is, the redox potential (ORP) shifts to the reduction side when the pH is large (alkaline), and the redox potential shifts to the oxidation side when the pH is small (acidic). Here, when the drinking water-containing water in this embodiment is ingested by mammals including humans, what is important as the active oxygen scavenging ability in vivo is not the pH but the redox potential (ORP) and / Or dissolved hydrogen concentration (DH).

  The manufacturing apparatus 20 further includes a hydrogen gas pressure control unit 103. Based on the on-line measurement result by the flow cell sensor 101, the pressure control unit 103 adjusts the hydrogen gas in the hydrogen gas circulation unit of the hydrogen gas dissolution module so that the dissolved hydrogen concentration in the hydrogen-containing water is within a predetermined range. So-called negative feedback control is performed to control the melting pressure.

  On the other hand, as described above, if the dissolved hydrogen concentration (DH) is directly measured in a continuous process with a dissolved hydrogen meter (hydrogen concentration measuring device) Bionics Co., Ltd. BIH-50D, etc., it is manufactured in a continuous process. The content of hydrogen contained in the hydrogen-containing water can be evaluated with much higher accuracy than when measured offline with a general ORP (redox potential) meter. Therefore, according to this embodiment, it is possible to evaluate the hydrogen content, which is said to have an effect of preventing oxidative damage of DNA, with much higher accuracy than before.

  Here, it is preferable to perform piping design so that the pressure applied to the hydrogen-containing water during the period from the subsequent stage of the hydrogen-dissolving membrane module 4 to the filling of the container is always maintained at a certain pressure (positive pressure). That is, it is preferable not to provide many bent parts and open parts in the middle of the pipe or to change the pipe diameter greatly in the middle. In this way, if many bent parts or open parts are provided in the middle of the pipe, or if the pipe diameter is greatly changed in the middle of the pipe, the pressure applied to the fluid will change at those parts, and the pressure will always be above a certain level (positive pressure) This is because the hydrogen-containing water is foamed during the flow through the pipe or at the time of filling / sealing, and the hydrogen gas in the hydrogen-containing water tends to escape.

  Here, the time during which the pressure applied to the hydrogen-containing water is released from the latter stage of the hydrogen-dissolving membrane module 4 to the filling of the container is preferably within 5 minutes in total, more preferably within 1 minute, most preferably It is preferable to control the flow rate so that it is within a total of 30 seconds. That is, if an open tank in which the hydrogen-containing water stays between the subsequent stage of the hydrogen-dissolving membrane module 4 and the filling of the container is provided, the residence time of the hydrogen-containing water in the open tank is preferably a total of 5 It is preferable to design the piping so that it is within minutes, more preferably within a total of 1 minute, and most preferably within a total of 30 seconds. In this way, since the time for releasing the pressure applied to the hydrogen-containing water can be shortened, the hydrogen gas in the hydrogen-containing water can be prevented from being released into the factory atmosphere or the atmosphere, and the hydrogen-containing and filled container is sealed. The dissolved hydrogen concentration in water can be kept high. In the first place, a closed tank may be used instead of an open tank so as not to generate time for the pressure applied to the hydrogen-containing water to be released between the subsequent stage of the hydrogen-dissolving membrane module 4 and the filling of the container. Good.

  Further, in order to send the hydrogen-containing water while maintaining the desired dissolved hydrogen concentration, the Reynolds number Re <4000 generated in the hydrogen-containing water during the period from the subsequent stage of the hydrogen-dissolving membrane module 4 to the filling of the container. Thus, it is desirable to adjust the pipe diameter and flow velocity. The Reynolds number is more preferably Re <2000, and most preferably Re <1500. This is because a large Reynolds number means that each fluid element moves separately and the flow field approaches turbulence. Therefore, the Reynolds number is also used as an index for distinguishing between turbulent flow and laminar flow. The Reynolds number when laminar flow transitions to turbulent flow is called the critical Reynolds number. For example, the critical Reynolds number Re2 in the flow in a circular pipe This is because it is set to 4,000 to 4,000. That is, when the Reynolds number Re <2,000, the fluid is laminar, and when the Reynolds number Re is 2,000 to 4,000, the fluid is in a transient state from laminar flow to turbulent flow. When the number Re> 4000, the fluid is in a turbulent state. That is, if the hydrogen-containing water is fed so that the Reynolds number Re satisfies such a condition from the latter stage of the hydrogen-dissolving membrane module 4 until the container is filled, the laminar flow or the turbulent flow is suppressed. Since water can be sent as a transitional state from laminar flow to turbulent flow, escape of hydrogen gas from hydrogen-containing water can be suppressed.

  The sterilization conditions after filling and sealing are preferably 65 to 95 ° C. and 10 to 30 minutes. Under these conditions, hydrogen gas emission due to sterilization after filling and sealing can be reduced, and drinking hydrogen-containing water having a higher hydrogen concentration can be obtained.

  According to the method for producing hydrogen-containing water for beverages of the present invention, hydrogen gas can be dissolved in raw water in a short time, and since it can be produced continuously, the productivity is excellent. In addition, juice, coffee drink, cocoa drink, by adding one or more selected from fruit juice, vegetable extract, cacao extract, coffee extract, tea extract, herbal extract, honey, sweetener and lactic acid bacteria, It can be made into beverages such as tea drinks and lactic acid drinks.

  In this embodiment, the hydrogen gas supplied to the hydrogen gas dissolution module 4 is a hydrogen gas generated by electrolyzing the raw water, but a hydrogen gas cylinder or the like is arranged instead of the electrolyzer 7, You may make it supply hydrogen gas to the hydrogen gas melt | dissolution module 4 from a hydrogen gas cylinder.

  In this case, the pressure of the hydrogen gas supplied from the electrolyzer 7 or the hydrogen gas cylinder to the hydrogen gas dissolution module 4 is determined based on the online measurement result by the flow cell sensor 101 so that the dissolved hydrogen concentration in the hydrogen-containing water is predetermined. It is designed to control the dissolution pressure of hydrogen gas in the hydrogen gas circulation part 4b of the hydrogen gas dissolution module 4 so as to be within the range. Such control is not particularly difficult. For example, it may be controlled by a computer in which a control program is incorporated, or may be controlled by combining a sequence of a relay mechanism in the control system. In any case, a researcher / engineer in this field can construct a control mechanism for performing such negative feedback control using a known technique as appropriate.

The hydrogen-containing water may be diluted and mixed with another aqueous solution such as degassed water.

<Embodiment 2>
Other embodiment of the manufacturing apparatus of the hydrogen containing water for drinks is described using FIG. This manufacturing apparatus has the same basic configuration as the manufacturing apparatus of the above embodiment, but the deaerated water is subjected to electrolytic treatment between the deaerator 3 and the hydrogen gas dissolution module 4 to perform electrolytic acid water and electrolysis. An electrolysis apparatus 8 that generates alkaline water is different in that it is arranged. Examples of the electrolysis apparatus 8 include a diaphragm type electrolysis apparatus having an ion permeable diaphragm between a cathode and an anode.

  The cathode chamber 8 a (electrolytic alkaline water production side) of the electrolysis apparatus 8 is connected to the raw material water circulation part 4 a of the hydrogen gas dissolution module 4. A draft pipe L11 is connected to the anode chamber 8b (electrolytic acid water production side) of the electrolysis apparatus 8.

Next, other embodiment of the manufacturing method of the hydrogen containing water for drinks of this invention using this manufacturing apparatus is described. In addition, the description of the same part as the said embodiment is abbreviate | omitted.

  In this embodiment, the raw water (degassed water) deaerated by the deaerator 3 is supplied separately to the cathode chamber 8a and the anode chamber 8b of the electrolyzer 8, and is subjected to electrolysis here for the anode chamber 8b side. Electrolytic acid water and electrolytic alkaline water are generated from the cathode chamber 8a side. In this case, the amount of electrolytic alkaline water produced can be increased more than the electrolytic acid water by increasing the amount of water supplied to the cathode chamber 8a than the amount of water supplied to the anode chamber 8b. Further, the pH of the obtained electrolytic alkaline water can be appropriately adjusted by changing the electrolysis conditions in the electrolysis apparatus 8. However, since the pH as drinking water needs to be in the range of about 6.5 to 8.5, when the pH of the obtained electrolytic alkaline water is too high, it is mixed with raw material water, electrolytic acid water, or the like. And it is preferable to adjust pH to 6.5-8.5. Further, if the electric conductivity of the raw material water supplied to the electrolyzer 8 is too low, the applied voltage and applied current during the electrolysis process increase, so that sodium ions, potassium ions, etc. are added to increase the electric conductivity between 5 and 5. It is preferable to adjust to 2,000 μs / cm, and more preferable to adjust to 100 to 1000 μs / cm.

  And the electrolytic alkaline water produced | generated with the electrolysis apparatus 8 is supplied to the raw material water distribution | circulation part 4a of the hydrogen gas melt | dissolution module 4, and hydrogen gas is supplied to the hydrogen gas distribution | circulation part 4b from the piping L6, and the inside of the hydrogen gas communication part 4b is supplied. Pressurize to dissolve hydrogen gas. In addition, the electrolytic acid water produced | generated with the electrolyzer 8 may be drained as it is, may be used as washing water etc., may be supplied to the electrolyzer 7, and may be utilized as a hydrogen generation source.

  Then, the raw water (gas dissolved water) in which hydrogen gas is dissolved in the hydrogen gas dissolution module 4 is subjected to UV irradiation and UHT treatment in the UV / UHT sterilizer 5 to kill germs and microorganisms. Filter with an outer filtration membrane. And as needed, after adding 1 or more types chosen from fruit juice, vegetable extract, cacao extract, coffee extract, tea extract, herbal extract, honey, sweetener, and lactic acid bacteria, it is in filling apparatus 6 Then, after filling various containers such as aluminum bags with spouts and aluminum cans and sealing them, hydrogen-containing water for beverages can be produced by sterilization treatment.

  According to this embodiment, the raw water is electrolyzed by the electrolyzer 8, and hydrogen gas is contained in the electrolytic alkaline water produced here. Therefore, oxidation of the hydrogen-containing water can be performed without using chemicals. The reduction potential can be further reduced, and beverage-containing hydrogen-containing water with higher reducibility can be produced.

  In any of the embodiments, when filling and sealing various containers such as an aluminum bag with a spout and an aluminum can with the filling device 6, the gap generated during the filling is reduced as much as possible. It is preferable that the contained water is filled in a form in which oxygen (air) is hardly involved. Also, in the case of sealing after filling, it is preferable to seal after removing oxygen (air) as much as possible by dropping liquid nitrogen into the opening of the container.

  And when filling the aluminum bag with a spout, it is preferable that the thickness of the aluminum film in the composite film which comprises the aluminum bag with a spout is 6 micrometers or more in order to reduce oxygen permeability. More preferably, it is 9 μm or more, and particularly preferably 15 μm or more. From the viewpoint of manufacturing cost, the thickness of the aluminum film is usually 50 μm or less.

<Description of effects>
Hereinafter, the effect in the manufacturing method of the hydrogen containing water for drinks of said Embodiment 1 and Embodiment 2 is demonstrated. According to the method for producing hydrogen-containing water for beverages, the raw water is supplied to the raw water circulation part of the hydrogen gas dissolution module 4 and the pressurized hydrogen gas is supplied to the hydrogen gas circulation part of the hydrogen gas dissolution module 4. Therefore, the hydrogen gas supplied to the hydrogen gas circulation part is dissolved in the raw material water passing through the gas permeable membrane and flowing through the raw material water circulation part 4a due to the partial pressure difference, and the raw material water circulation part 4a of the hydrogen gas dissolution module 4 A large amount of hydrogen gas is dissolved in the raw material water discharged from.

  Moreover, in this method, since hydrogen-containing water is produced, filled, and sealed in a continuous manner rather than a batch method, when the dissolved hydrogen water is extracted from the hydrogen gas dissolution module 4, the hydrogen gas is dissolved in the raw material water. Since the dissolved hydrogen water is extracted through a pipe-shaped extraction pipe having a diameter comparable to the diameter of the hydrogen gas dissolution module 4 to be used, the pressure applied to the dissolved hydrogen water as a fluid is determined by Bernoulli's theorem described later. There is no significant reduction compared to the inside.

  Here, FIG. 5 is a conceptual diagram for explaining Bernoulli's theorem (or Venturi effect). As shown in this figure, the venturi mechanism is a mechanism that generates a lower pressure than the low speed portion by increasing the flow velocity by restricting the flow of fluid. In such a mechanism, if the flow cross-sectional area is narrowed when the flow rate is constant, the flow velocity increases. When the fluid is incompressible, the pressure decreases as the flow rate increases from Bernoulli's theorem. This is a mechanism used for carburetors, atomizers, air brushes, etc. of engines that take in gasoline when handling liquids.

  In other words, if Bernoulli's theorem (or the Venturi effect) is applied to this embodiment, a pipe-shaped pipe having a diameter comparable to the diameter of the hydrogen gas dissolution module 4 used when dissolving hydrogen gas in the raw material water is considered. Since dissolved hydrogen water is extracted through the outlet pipe, the flow rate does not increase rapidly during the process, and the pressure does not decrease extremely. Therefore, the pressure applied to the dissolved hydrogen water as a fluid is not greatly reduced compared to the inside.

  Therefore, when a filler with a general structure is used to fill and seal dissolved hydrogen water from a pipe-shaped extraction pipe into a highly airtight container, the filler filling port and the opening of the highly airtight container are used. Even in the gaps inevitably existing between the two, the bubbling of hydrogen gas in the dissolved hydrogen water is suppressed. Therefore, even in the gap part inevitably present between the filler filling port and the opening of the highly airtight container, hydrogen in the dissolved hydrogen water is difficult to escape into the filling atmosphere, and oxygen (air) in the filling atmosphere It is difficult to get caught in dissolved hydrogen water.

  In addition, in this method, hydrogen-containing water is produced in a continuous process, not a batch process, and is filled and sealed. There is no such a tendency that oxygen (or air) in the atmosphere or factory atmosphere is easily mixed. As a result, in this method, in addition to being able to achieve a high dissolved hydrogen concentration in a state where hydrogen gas is dissolved in the raw water by the hydrogen gas dissolution module, hydrogen escape and oxygen (air) during subsequent extraction and filling Therefore, the hydrogen concentration in the dissolved hydrogen water sealed inside the highly airtight container can be maintained as high as the dissolved hydrogen concentration realized in the hydrogen gas dissolution module 4.

  In this method, the hydrogen content in the dissolved hydrogen water is measured as the dissolved hydrogen concentration (DH). Therefore, as will be described later, the concentration of dissolved hydrogen in dissolved hydrogen water is not greatly changed depending on various conditions such as pH, as often occurs when measured as an oxidation-reduction potential (ORP). The hydrogen content in the dissolved hydrogen water can be evaluated by an appropriate index as an index to be evaluated.

  Furthermore, in this method, after dissolving hydrogen gas in raw water in a continuous manner, the content of hydrogen in the dissolved hydrogen water is further dissolved online as an appropriate index using the flow cell sensor 101 or the like in the continuous process. Measured as the hydrogen concentration (DH), and based on the on-line measurement result, in the hydrogen gas circulation part 4b of the hydrogen gas dissolution module 4 so that the dissolved hydrogen concentration in the hydrogen-containing water falls within a predetermined range. So-called negative feedback control is performed to control the dissolution pressure of hydrogen gas. At this time, the negative feedback control method is not particularly limited. For example, the negative feedback control method may be performed by opening and closing the valve 47, or the electrolytic strength when water is electrolyzed to generate hydrogen. Control may be performed, or hydrogen-containing water may be diluted and mixed with another aqueous solution such as degassed water.

  Therefore, operating conditions (changes in factory atmosphere due to season, time, weather, etc.), raw water (changes in quality of tap water and natural water due to season, time, weather, etc.), raw material gas (for each gas supply lot) Even if there are variations in conditions such as (variation), these variations are alleviated by the negative feedback control described above, and variation in the hydrogen concentration for each lot of dissolved hydrogen water obtained in this continuous process is suppressed.

  Thus, according to this method, hydrogen can be efficiently contained in the raw water in a short time, so that stable quality hydrogen-containing water for drinking can be produced with high productivity.

  Further, in the method for producing hydrogen-containing water for beverages of this embodiment, before supplying raw water to the hydrogen gas dissolution module, water is passed through the nanofilter and the electrical conductivity is adjusted to 5 to 2,000 μS / Cm. It is preferable to do. By passing raw material water through the nanofilter, mineral components other than sodium ions and potassium ions can be captured by the nanofilter, so that it is suitable for drinking and can be produced with hydrogen-containing water for drinking with higher reducing power.

  In addition, in the method for producing hydrogen-containing water for beverages of this embodiment, before supplying raw water to the hydrogen gas dissolution module 4, water is passed through the RO membrane, and then metal ions are added to increase the electrical conductivity. It is preferable to adjust to 5 to 2,000 μs / cm. The RO membrane filtration process can effectively remove impurities in the raw material water, but even metal ions are removed by the RO membrane, so after adding the raw material water to the RO membrane, add metal ions. By adjusting the electrical conductivity to 5 to 2,000 μs / cm, it is possible to produce hydrogen-containing water for drinking that is suitable for drinking and has a higher reducing power.

  The method for producing hydrogen-containing water for beverages of the present embodiment uses a raw material water that has been passed through a nanofilter or RO membrane, and the hydrogen gas discharged from the raw material water circulation part 4a of the hydrogen gas dissolution module 4 is It is preferable to add at least one selected from fruit juice, vegetable extract, cacao extract, coffee extract, tea extract, herbal extract, honey, sweetener and lactic acid bacteria to the dissolved raw material water. According to this aspect, a beverage having a high reducing power can be produced.

  It is preferable that the manufacturing method of the hydrogen-containing water for drinks of this embodiment deaerates, before supplying raw material water to a hydrogen gas melt | dissolution module. By degassing the raw water, it becomes easy to dissolve hydrogen gas in the raw water, and the hydrogen-containing water for drinking having a high hydrogen concentration can be produced efficiently and in a short time.

  Before supplying raw material water to the hydrogen gas dissolution module 4, the manufacturing method of the hydrogen-containing water for drinks of this embodiment produces electrolytic acid water and electrolytic alkaline water by electrolytic treatment, and obtained electrolytic alkaline It is preferable to supply water to the raw material water circulation part 4a of the hydrogen gas dissolution module. There is a correlation between the pH and the oxidation-reduction potential, and the oxidation-reduction potential decreases as the pH is increased. Therefore, according to this aspect, since the pH of the hydrogen-containing water can be increased without using a drug or the like, it is possible to efficiently produce beverage-containing hydrogen-containing water with higher reducibility.

  In the method for producing hydrogen-containing water for beverages of the present embodiment, the electrolytic treatment is preferably performed after the raw water is deaerated. According to this aspect, the hydrogen-containing water for drinks with high reducibility can be manufactured efficiently.

  In the method for producing hydrogen-containing water for beverages of this embodiment, hydrogen gas obtained by electrolyzing a part of raw water is supplied under pressure to the hydrogen gas circulation part of the hydrogen gas dissolution module and the hydrogen gas dissolution module Hydrogen gas is dissolved in the raw water supplied to the raw water circulation section, or water is electrolyzed, and the obtained hydrogen gas is pressurized and supplied to the hydrogen gas circulation section of the hydrogen gas dissolution module. Thus, it is preferable to dissolve the hydrogen gas in the raw water supplied to the raw water circulation section of the hydrogen gas dissolution module. According to this aspect, it is possible to save troubles such as preparation / replacement of a hydrogen gas cylinder or the like and management of the remaining amount of hydrogen gas.

  In the method for producing hydrogen-containing water for beverages of this embodiment, the hydrogen-containing water for beverages is preferably a favorite beverage. This is because if it is a favorite beverage, it is easy to encourage consumers to drink, and the selling unit price increases and the economic value also increases.

  As mentioned above, although embodiment of this invention was described with reference to drawings, these are the illustrations of this invention, Various structures other than the above are also employable.

  EXAMPLES Hereinafter, although an Example demonstrates this invention further, this invention is not limited to these.

<Example 1>
Using the production apparatus shown in FIG. 1, the hydrogen-containing water for drinking was produced using the hydrogen gas dissolution module shown in FIG.

Tap water was supplied to the activated carbon tank 1 at a flow rate of 101 / min for dechlorination. Next, the dechlorinated tap water was supplied to a filtration device 2 equipped with an NF filter or an MF filter at a flow rate of 101 / min for filtration. At this time, the electrical conductivity of the filtrate discharged from the filtration device 2 was 110 μs / cm. Next, the filtered water (filtered tap water) was deaerated by the deaerator 3 to be deaerated water, and the concentration of gas dissolved in the deaerated water was set to 1 ppm or less. Thereafter, the deaerated water is cooled in advance, and the deaerated water is supplied into the hollow fiber from the raw material water inlet 43 of the hydrogen gas dissolving module shown in FIG. 2, and the hydrogen gas is supplied from the hydrogen gas inlet 45 to the container 41. The pressure in the container was increased to 1.0 kgf / cm ³ with hydrogen gas. At this time, the hydrogen concentration of tap water discharged from the hydrogen gas dissolution module 4 measured by the flow cell sensor 101 was 2.0 to 2.5 ppm. That is, if the hydrogen concentration is less than 2.0 ppm, the valve 47 is loosened to increase the supply pressure of hydrogen gas to the hydrogen gas dissolution module 4, and if the hydrogen concentration exceeds 2.5 ppm, the valve 47 is throttled. Thus, the supply pressure of hydrogen gas to the hydrogen gas dissolution module 4 was decreased. And after performing UV sterilization, filling the aluminum bag with a spout and sealing, it heat-sterilized at 85 degreeC for 30 minutes, and manufactured the hydrogen containing water for drinks.

  The hydrogen concentration of drinking hydrogen-containing water filled in the spout-added aluminum bag immediately after production is approximately 1.0 to 1.6 ppm (pH = 6.8 to 7.5, ORP = −600 to −650 mV). Yes, there was no variation in hydrogen concentration for each product, and water with high hydrogen concentration could be produced with high productivity.

  In this way, when manufacturing high-concentration water and filling / sealing, the variation in hydrogen concentration from lot to lot, batch production using a normal pressurized tank, and continuous using this membrane module As a result of comparative measurement with the case where production was performed with negative feedback control in the formula, n = 10 in the batch formula, the average of the hydrogen dissolved concentration was 1.06 ppm, and the standard deviation was 0.58. In the case of n = 10, the hydrogen dissolved concentration averaged 1.46 ppm, and the standard deviation was 0.13.

  Furthermore, the hydrogen concentration in the manufacturing process (in the membrane module or in the pressurized tank) and the reduction of the hydrogen concentration after filling and sealing are usually As a result of comparative measurement between the batch-type production using the pressurized tank and the case of production using the current hydrogen gas dissolution module 4 with negative feedback control, n = 10 in the batch-type On average, the reduction was about 0.6 ppm, but in the continuous type, the reduction of hydrogen concentration was clearly suppressed, with an average of about 0.2 ppm when n = 10.

  In the above, this invention was demonstrated based on the Example. It is to be understood by those skilled in the art that this embodiment is merely an example, and that various modifications are possible and that such modifications are within the scope of the present invention.
