Description

  The present invention relates to a method for producing functional drinking water containing stabilized nanobubble nuclei and a functional drinking water containing stabilized nanobubble nuclei produced by the production method.

  In recent years, attention has been focused on nano-sized bubbles in water, that is, water containing nanobubbles of a desired gas, and application to various fields such as medical treatment, agriculture, aquaculture and aquaculture has been achieved.

  For example, Non-Patent Document 1 describes the basics and engineering applications of microbubbles and nanobubbles. Non-Patent Documents 2 to 4 describe the application to the medical field utilizing the bactericidal ability of ozone nanobubbles, the cell activation ability of oxygen nanobubbles, and the tissue preservation ability. Non-Patent Document 5 describes the application of ozone microbubbles to agriculture, and Non-Patent Document 6 describes the application of micro or nanobubbles to the aquaculture and aquaculture fields. In addition, Non-Patent Document 1 describes, as a nanobubble analysis method, a measurement method using a dynamic light scattering photometer and a measurement method using an electron spin resonance method (ESR) for measuring free radicals caused by nanobubbles. Yes.

  Furthermore, although the generation mechanism of microbubbles, the mechanism of stabilization as nanobubbles, and the conceptual method thereof are described in Non-Patent Document 1, a specific example of a method for producing oxygen nanobubble water is disclosed in Patent Document 1. Are listed.

  That is, in the method for producing oxygen nanobubbles described in Patent Document 1, oxygen is supplied to water mixed with electrolyte ions of minerals as microbubbles having a diameter of 10 to 50 μm, and shock waves or water accompanying water discharge are generated. By applying physical stimuli such as compression, expansion, and vortex generated during the flow of gas, the microbubbles are reduced. At this time, hydrogen ions, hydroxide ions, and electrolyte ions are concentrated at the gas-liquid interface and reduced. By acting as a shell surrounding the bubble, the reduced microbubbles, that is, oxygen nanobubble nuclei are stabilized and exist in water.

  In the present invention, microbubbles in which hydrogen ions, hydroxide ions, and electrolyte ions surround and stabilize the microbubbles are referred to as nanobubble nuclei. Further, as described above, the operation of applying a physical stimulus to reduce microbubbles is referred to as “collapse” in the present invention.

  Water containing nanobubble nuclei, particularly oxygen nanobubble water containing nanobubble nuclei of oxygen has the ability to activate homeostasis as described above, and has the effect of enhancing homeostasis in living organisms, and generally possessed by living organisms The ability to improve immunity and resistance to the surrounding environment.

  Therefore, when nanobubble water containing stabilized nanobubble nuclei is used as drinking water, the potency of tissue preservation, repair, and regeneration is strengthened, or adhesion factor that causes arteriosclerosis is applied to the defective endothelium. The effect of suppressing invasion and the like is expected to prevent lifestyle-related diseases and promote health, that is, it can be used as functional water or functional drinking water.

  By the way, the oxygen nanobubble water shown in Patent Document 1 described above uses water mixed with electrolyte ions of minerals as raw water, and as this raw water, for example, seaside well water containing salt is used. be able to. However, the water in which oxygen is supplied to such raw water as microbubbles and is crushed by physical stimulation to stabilize oxygen nanobubble nuclei has a salt concentration, and impurities such as germs, Mn, and Mg Since it is mixed, it cannot be used as drinking water as it is.

  For this reason, conventionally, when drinking water is produced, the seaside well water prepared at a predetermined salinity concentration is used as the raw water, and after supplying oxygen microbubbles and crushing, the pore size is 10 mm (1 nm). A treatment for removing salt by passing through a reverse osmosis membrane of a certain degree is performed. The removal of salt by the reverse osmosis membrane is performed, for example, in two stages.

  As described above, when producing drinking water containing nanobubbles such as oxygen nanobubbles using raw water containing salt like seaside well water, as described above, the step of removing salt by a reverse osmosis membrane Since it is essential, both initials and running are expensive.

  In addition, since the pores are permeated through a reverse osmosis membrane having a size of about 10 mm, nanobubble nuclei generated in the crushing process may be removed together with salt.

On the other hand, in order to eliminate the salt removal process by the reverse osmosis membrane and reduce costs, potable water that does not substantially contain salt, such as well water in the mountains, is used as a raw material, and oxygen is supplied as microbubbles for collapse. Even if it makes it, since it does not contain salt content substantially, it is difficult to produce | generate the nanobubble nucleus stabilized equivalent to the raw material water containing salt content. However, although drinking water such as well water in the mountains is substantially free of salt, it is stable in quantity but produces stable nanobubble nuclei.
The present invention has been devised for the purpose of solving the above-described problems. That is, the present invention proposes a method capable of producing functional drinking water containing stabilized nanobubble nuclei at a low cost. .

  In order to solve the above-mentioned problems, the present invention supplies gas to salt water-containing raw water as microbubbles having a size of 50 μm or less, and is crushed by physical stimulation, and then generated by permeating a reverse osmosis membrane. The first raw material drinking water and the second raw drinking water generated by supplying gas as microbubbles having a size of 50 μm or less to the drinking water substantially free of salt and being crushed by physical stimulation. The present invention proposes a method for producing functional potable water containing stabilized nanobubble nuclei characterized in that after mixing, crushing is again generated by physical stimulation.

  In the present invention, it is proposed that the above-described production method is prepared by diluting the salinity concentration of the raw material water containing salt with the first raw material drinking water generated by permeating the reverse osmosis membrane.

  Moreover, in this invention, in said manufacturing method, it proposes setting the mixing ratio of the 1st raw material drinking water and the 2nd raw material drinking water to the range of 2: 8-8: 2.

  Moreover, in this invention, in said manufacturing method, it proposes setting the mixing ratio of the 1st raw material drinking water and the 2nd raw material drinking water to 3: 7-6: 4.

  In the present invention, it is proposed that the salt concentration of the first raw material drinking water is set to 0.9% or in the vicinity thereof in the above manufacturing method.

  In the present invention, it is proposed that the gas is oxygen in the above manufacturing method.

  Moreover, in this invention, the functional drinking water containing the stabilized nano bubble nucleus manufactured using the above manufacturing method is proposed.

  As a result of diligent research and experiments, the inventor supplied gas as raw material water containing salt as microbubbles with a size of 50 μm or less, collapsed by physical stimulation, and then passed through a reverse osmosis membrane. The first raw material drinking water and the second raw drinking water generated by supplying gas as microbubbles having a size of 50 μm or less to the drinking water substantially free of salt and being crushed by physical stimulation. After mixing, crushing was again performed by physical stimulation, and stabilized nanobubble nuclei equivalent to those obtained by supplying microbubbles to the raw material water containing salt and being crushed could be generated.

  The raw material water containing salt can be prepared by diluting with the first raw material drinking water produced by permeating the reverse osmosis membrane.

  Since the first raw material drinking water is crushed by supplying gas as microbubbles to the raw material water containing salt, stabilized nanobubble nuclei are efficiently generated, and thus permeate the reverse osmosis membrane. In some cases, nanobubble nuclei may be removed, but there is a possibility that nanobubble nuclei with a smaller diameter may remain. By performing crushing in such a state, salt content is substantially reduced. Even if it is not included, nanobubble nuclei are efficiently generated.

  On the other hand, since the drinking water for producing the second raw material drinking water does not substantially contain salt, it is difficult to produce nanobubble nuclei as compared with the case of containing salt, and the produced stable water There are few nanobubble nuclei.

  From these facts, the first raw potable water has high cost and high performance, whereas the second raw potable water has low cost and low performance.

  Therefore, the mixing ratio of the first raw drinking water and the second raw drinking water can be set in consideration of the cost performance of the produced functional drinking water.

  For example, by setting the mixing ratio of the first raw material drinking water and the second raw material drinking water in the range of 2: 8 to 8: 2, necessary performance can be exhibited, and particularly, from 3: 7 to The range of 4: 6 provides a good balance between cost and performance.

  Next, in the above-described invention, the salinity concentration of the raw material water containing the salinity needs to be set in consideration of the generation efficiency of nanobubble nuclei by crushing and the necessary pressure for permeation through the reverse osmosis membrane. If it is too high, the generation efficiency of nanobubble nuclei will be low, and if it is too high, the pressure required to permeate the reverse osmosis membrane will be too high.

  From this viewpoint, the salinity concentration of the raw water containing the first salinity is preferably set to 0.9%, which is equivalent to physiological saline, or the vicinity thereof.

  On the other hand, ozone, carbon dioxide, nitrogen, air or the like can be used as the gas generated as the nanobubble nucleus, but oxygen is the best drinking water.

FIG. 1 is a schematic system diagram showing the flow of the manufacturing method of the present invention. FIG. 2 shows an example of ESR measurement results of functional drinking water produced by the production method of the present invention.

  Embodiments of the manufacturing method of the present invention will be described below with reference to the accompanying drawings.

  In FIG. 1, reference numeral 1 indicates a raw material water (or a tank thereof) containing salt, and this raw water 1 is supplied to a crushing container 2. The crushing container 2 is supplied with gas, in this case oxygen, from the gas cylinder 3 as microbubbles having a size of 50 μm or less, and in this state, physical crushing is applied to perform crushing.

  That is, oxygen supplied to the crushing container 2 as microbubbles having a size of 50 μm or less is reduced by physical stimulation. At this time, hydrogen ions, hydroxide ions and electrolyte ions in water are concentrated at the gas-liquid interface. Thus, it acts as a shell surrounding the reduced microbubbles and is stabilized and present in water as reduced microbubbles, that is, oxygen nanobubble nuclei.

  Next, the water containing the stabilized oxygen nanobubble nuclei permeates through the reverse osmosis membrane 4 to remove salt and impurities such as bacteria, Mn, and Mg, and is generated as the first raw material drinking water. The removal of salt and the like by the reverse osmosis membrane 4 may be performed in only one stage, or may be performed in a plurality of stages, for example, two stages.

  Here, the raw water is, for example, seaside well water having a salinity of 2.0%, and such salinity is a desired salinity, for example, 0.9% equivalent to physiological saline or the vicinity thereof as described later. In order to achieve this concentration, the first raw drinking water that has passed through the reverse osmosis membrane 4 can be supplied to the raw water 1 and diluted to obtain a desired salt concentration.

  Reference numeral 5 denotes potable water (or a tank thereof) that does not substantially contain salt. The potable water 5 is supplied to the crushing container 6. The crushing container 6 is supplied with gas, in this case, oxygen, as microbubbles having a size of 50 μm or less from the gas cylinder 7, and in this state, physical crushing is applied to perform crushing. Raw material drinking water is produced.

  Since the drinking water for producing the second raw material drinking water is substantially free of salt, it is difficult to produce nanobubbles compared to the case of containing salt, and the produced stabilized water is stabilized. There are few nanobubble nuclei.

  Therefore, the first raw material drinking water and the second raw material drinking water are supplied to the crushing container 8 at a predetermined ratio and mixed. The crushing container 8 is supplied with gas, in this case oxygen, from the gas cylinder 9 as microbubbles having a size of 50 μm or less. In this state, physical crushing is applied to perform crushing. Functional drinking water according to the invention is produced. Reference numeral 10 denotes functional drinking water or a tank thereof.

  At this time, when the first raw material drinking water is permeated through the reverse osmosis membrane 4 to remove salt or the like, the oxygen nanobubbles are removed to some extent. Since the gas is supplied as microbubbles and crushed, stabilized nanobubbles are efficiently generated, and even smaller diameter nanobubbles may remain even after going through the reverse osmosis membrane. By performing crushing in such a state, nanobubbles are efficiently generated even when substantially no salt is contained.

  On the other hand, since the potable water as the raw material for generating the second raw potable water does not substantially contain salt, it is difficult to generate nanobubbles as compared with the case of containing salt, but the container for crushing 8 is mixed with the first raw material drinking water and again undergoes a crushing process, so that the mixture of these raw material drinking waters is crushed by supplying oxygen microbubbles to the raw material water containing salt It is possible to generate stabilized nanobubbles equivalent to those collapsed by supplying oxygen microbubbles.

  FIG. 2 shows an example of the ESR measurement result of the functional drinking water produced by the production method of the present invention, and nanobubbles are contained in the functional drinking water 10 due to the peak corresponding to the free radical in the measurement result. I understand that.

  As described above, the first raw potable water has high cost and high performance, whereas the second raw potable water has low cost and low performance. The mixing ratio of the raw material drinking water can be set in consideration of the cost performance of the produced functional drinking water 10.

  For example, by setting the mixing ratio of the first raw material drinking water and the second raw material drinking water in the range of 2: 8 to 8: 2, necessary performance can be exhibited, and particularly, from 3: 7 to The range of 4: 6 provides a good balance between cost and performance.

  In the above production method, the salt concentration of the raw material water 1 containing salt must be set in consideration of the generation efficiency of nanobubble nuclei by crushing and the necessary pressure for permeation through the reverse osmosis membrane 4. If it is too high, the generation efficiency of nanobubbles is low, and if it is too high, the pressure required for permeation through the reverse osmosis membrane becomes too high.

  From this viewpoint, the salinity concentration of the raw water 1 containing the first salinity is preferably set to 0.9%, which is equivalent to physiological saline, or the vicinity thereof.

  Since the present invention is as described above, for example, by drinking the produced functional drinking water every day without missing, it is replaced with a part of the body fluid and incorporated into a part of the body tissue constituent fluid, Because it works to maintain the homeostasis, it is expected to be effective in delaying and suppressing lifestyle-related diseases and metabolic symptoms.
