Description

[Technical Field]

[0001] The present invention generally relates to a technique for producing aromatic electrolyzed water. [Background technology]

[0002] In recent years, there has been a demand for the development of cleaning agents that are both environmentally friendly and safe for humans. Although conventional synthetic detergents have excellent cleaning power, the harmful effects on humans and the environment caused by the chemicals and additives they contain have been pointed out, and there is a growing need for alternative technologies that utilize naturally derived ingredients.

[0003] On the other hand, alkaline electrolyzed water obtained by electrolysis of water is known to have cleaning effects, and various applications are being considered. Patent Document 1 discloses a technology that provides a cleaner that combines the cleaning power for oily stains with a fragrant fragrance by adding fragrance to alkaline electrolyzed water and removing oil by filtration. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6093964 Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present application have been continuously engaged in the production, quality evaluation, and application development of aroma distilled water, which is obtained as a by-product in the manufacturing process of aroma products. As a result, they have confirmed that aroma distilled water is mainly distributed in Japan as a miscellaneous item, and although it may be treated as a cosmetic depending on its use and labeling, there are insufficient practical guidelines and standardization, and specific and practical methods for its use in cleaning have not yet been established.

[0006] Furthermore, the structure of Patent Document 1, which is based on the post-addition of fragrances and removal of oils, leaves room for improvement in terms of additive management and process load, and is not consistent with the trend of directly valuing the by-product, aromatic distilled water. Therefore, a new process design is needed that maximizes the functionality of electrolyzed water while utilizing naturally derived aromatic components.

[0007] The present invention has been made in light of the above, and proposes a method for producing aromatic electrolyzed water using aromatic distilled water obtained by distilling plant raw materials. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention is configured to include a process of supplying aromatic distilled water obtained by distilling plant raw materials as water to be electrolyzed to an electrolytic cell and electrolyzing it, and a process of recovering alkaline aromatic electrolyzed water from the electrolytic cell. [Effects of the Invention]

[0009] According to the present invention, it is possible to provide aromatic electrolyzed water produced using aromatic distilled water obtained by distilling plant raw materials. Objects, means, and effects not described above will become clear from the following description of the embodiments. [Brief explanation of the drawings]

[0011] (I) First embodiment The configurations, processing procedures, and other elements disclosed below are provided to explain embodiments of the present invention and are not intended to limit the present invention. The description based on the drawings is intended to facilitate understanding, and the shape, arrangement, function, and the like of elements may be omitted or simplified as necessary. The present invention is not limited to one or more of the disclosed embodiments, and may be realized by functionally or structurally equivalent means or other means achieving a technically similar purpose, within the scope that can be understood by those skilled in the art from the entire specification. Unless otherwise specified, each element in this specification is interpreted as including "at least one." Furthermore, words described in the singular include the plural, and words described in the plural include the singular. Furthermore, terms used in this specification are not limited to a specific meaning unless the context is clear, and should be interpreted appropriately by those skilled in the art. For example, the expression "including" is interpreted as meaning not limited to the listed items.

[0012] In the prior art, essential oils are added to electrolyzed water after it is produced to stabilize the dispersion, with the aim of imparting fragrance and functionality to the liquid composition. Based on the fact that essential oils are insoluble in water, the prior art uses a solvent or solubilizer in combination to facilitate degreasing, but requires the handling of flammable components, management of solvent odor, management of irritation, and management of re-adhesion of residues.

[0013] In this regard, the manufacturing system according to the present embodiment employs a configuration in which aroma distilled water (hydrosol) is used as the electrolyzed raw water (raw water). This manufacturing system directly electrolyzes aroma distilled water containing trace amounts of water-soluble aroma components and fine oil droplets in the aqueous phase, thereby avoiding the addition of solubilizing agents or organic solvents, and achieving formulation stability that contributes to uniform wetting and spreading during spraying and reduced residual feeling after use. While this manufacturing system is based on the design principle of aroma electrolyzed water without the addition of essential oils, it does not preclude the option of adding essential oils after electrolysis depending on the application requirements. This manufacturing system allows for the addition of small amounts of essential oils and the use of naturally occurring solubilizing agents (e.g., lecithin, saponin, glycolipids) to adjust dispersion stability only when fragrance impartation or functional adjustment is required.

[0014] This manufacturing system achieves a balance between maintaining fragrance notes, formulation stability, usability, and safety, while suppressing the effects of side reactions through the selection of electrolysis conditions and configuration. This manufacturing system can be applied to wiping operations in situations where the use of water is difficult. One example of the operation mode of this manufacturing system is to spray aromatic electrolyzed water onto the target surface in a water outage or outdoor environment, and then remove it with a paper wipe. For this manufacturing system, evaluation procedures to confirm the effectiveness of the operation mode have been established for the evaluation items described below, and the scope of application can be clarified by optimizing the conditions of material, type of dirt, liquid volume, and contact time.

[0015] According to this manufacturing system, by electrolyzing the aroma distilled water itself, which is obtained as a by-product of aroma oil production, it is possible to provide electrolyzed aroma water that combines cleansing and aromatic effects while effectively utilizing essential oil-derived components, and that can be developed into a variety of products using local specialties.

[0016] The following detailed description will be given with reference to the drawings. In this specification, identical or functionally similar components shown in the drawings are designated by common reference numerals. To simplify the drawings, obvious details such as piping, joints, small-diameter valves, sensors, check valves, auxiliary equipment, and auxiliary containers may be omitted unless otherwise specified.

[0017] Fig. 1 is a diagram showing an example of a process configuration related to a manufacturing system 100. Elements surrounded by dotted lines and dotted arrows in Fig. 1 represent optional elements or processes.

[0018] The manufacturing system 100 includes a distillation device 110 and an electrolysis device 120. The manufacturing system 100 supplies raw material 101 to the distillation device 110 to obtain aromatic distilled water 102 and aromatic oil 105. The manufacturing system 100 supplies aromatic distilled water 102 to the electrolysis device 120 to obtain aromatic electrolyzed water 103. The manufacturing system 100 performs an adjustment and blending process 130 and a filling and packaging process 140 as necessary to obtain a product 104.

[0019] The raw material 101 is a plant raw material (plant material) and is at least one of herbs, flowers, leaves, stems, branches, wood, bark, roots, rhizomes, seeds, fruits, peels, fruit pulp, resin, and by-products. Examples of the raw material 101 include by-products such as tea production residues, fruit processing residues, tree pruning branches and leaves, and wood processing by-products. The raw material 101 may be used alone or in combination with multiple materials, and may be subjected to pre-treatment such as washing, cutting, and crushing prior to the distillation process.

[0020] Product 104 is a liquid composition that is filled into a container, sealed, and labeled. Its primary use is household cleaning and deodorization, with optional applications for sterilization, antibacterial, and viral inactivation. Product 104 can be sprayed, wiped, or immersed on metal, resin, glass, ceramic, and textile surfaces. Examples of its applications include kitchens, windows and mirrors, bathrooms, textiles and interiors, toilets and areas around food waste, kitchen utensil sanitation, floor and tabletop wiping (diluted approximately 10 times before use), animal care areas, car interiors and exteriors, and pretreatment of heavy oils and grease in commercial kitchens. It can also be effectively applied to the display surfaces and exteriors of electronic devices (smartphones, tablets, and personal computer LCD displays, keyboards, and main units), televisions, various home appliances and their remote controls, microwave oven interiors, sunglasses lenses, and doorknobs and various handles. For areas where direct spraying is inappropriate, spraying onto a cloth and wiping can be used. Product 104 is primarily used for wiping and can be used in homes (around the kitchen, dishes, floors, walls, glass windows) as well as in facilities such as nursing homes, care facilities, daycare centers, and elementary schools, as well as on the glass and interiors of cars that are affected by exhaust fumes.

[0021] The distillation apparatus 110 receives raw material 101, such as citrus peels, citrus fruit pulp, coniferous tree branches and leaves, and herbs, and performs a distillation process with the primary purpose of extracting aroma oil 105. The distillation apparatus 110 produces aroma distilled water 102 as a result of the distillation process, and in operational practice, the aroma distilled water 102 is sometimes discarded due to lack of uses. In this regard, the production system 100 recovers the aroma distilled water 102 produced by the distillation apparatus 110, or receives aroma distilled water 102 supplied from an external source and uses it as raw water for the electrolysis apparatus 120.

[0022] The electrolysis device 120 electrolyzes aromatic distilled water 102 as raw water. The electrolysis device 120 recovers electrolyzed water discharged from the cathode side as aromatic electrolyzed water 103. The electrolysis device 120 can be operated either continuously or batchwise. The electrolysis device 120 can be configured with or without a diaphragm.

[0023] In the adjusting and blending step 130, the manufacturing system 100 can add inorganic salts such as sodium bicarbonate to the electrolyzed aroma water 103 to adjust the pH. In the adjusting and blending step 130, the manufacturing system 100 can mix plant essential oils to impart fragrance and functionality. In the adjusting and blending step 130, the manufacturing system 100 can add a naturally derived solubilizer as needed to impart dispersion stability. Note that even when plant essential oils are mixed after electrolysis, the manufacturing system 100 can adopt a process configuration that does not include a filtration step for the purpose of removing oil. However, even in this case, the manufacturing system 100 can adopt filtration for the purpose of removing solid foreign matter or for sanitary control, as long as the filtration is not for the purpose of removing oil.

[0024] The manufacturing system 100 can fill the aromatic electrolyzed water 103 or the liquid after the preparation and blending process 130 into a container, seal the container, and label the container in the filling and packaging process 140. The manufacturing system 100 can provide a product 104 as a liquid composition for use in household cleaning or deodorizing.

[0025] The basic process flow of the production system 100 involves recovering aroma distilled water 102, a by-product of the distillation apparatus 110's operation to extract aroma oil 105. This water is often discarded due to lack of uses. Alternatively, the system receives aroma distilled water 102 supplied from an external source. The aroma distilled water 102 is then supplied to the electrolysis apparatus 120 as raw water to produce electrolyzed aroma water 103. The production system 100 may omit the adjustment and blending process 130 and the filling and packaging process 140 depending on operational requirements. The production system 100 obtains a liquid with desired physical properties by appropriately selecting the temperature, flow rate, current value, and additive amount conditions while maintaining the order of the processes. The production system 100 achieves the same results regardless of the type of raw material 101, the type of distillation apparatus 110, the type of electrolysis apparatus 120, and whether or not the adjustment and blending process 130 is present, as long as the functional relationships shown in FIG. 1 are met.

[0026] FIG. 2 is a diagram showing an example of a distillation apparatus 110.

[0027] Distillation apparatus 110 comprises a still 210, a condenser 220, a cooler 230, an oil-water separator 240, a distillate tank 250, and a vacuum pump 260. The distillation apparatus 110 allows for temperature settings to be selected according to the compatibility with the raw material, and a condition of 100°C can be used for atmospheric distillation. For reduced-pressure distillation, conditions such as 70°C or 55°C can be used, and distillation (extraction) can be performed at an even lower temperature (for example, 40°C). The apparatus is configured to achieve a high oil recovery rate by using a sealed structure (including safety mechanisms such as a safety valve and exhaust port) to reduce loss of aroma components.

[0028] The still 210 is compatible with both a method in which the raw material 101 is directly charged and a method in which the raw material 101 is stored in a raw material holder (aroma macago) and processed. The still 210 heats the raw material 101 by indirect heating using steam supplied from a boiler or the like, generating steam containing aromatic components, which is then introduced to the condenser 220 via piping at the top. The still 210 is compatible with both normal pressure operation and reduced pressure operation. During reduced pressure operation, the vacuum pump 260 reduces the pressure in the still 210 and the condenser 220, achieving conditions for extraction while suppressing the generation of a burnt odor and deterioration of aromatic components.

[0029] Condenser 220 cools the steam guided from still 210 and converts it into condensed liquid. Cooler 230 supplies circulating cooling water to condenser 220, and by recirculating the cooling water, the discharge of passing water is suppressed. The condensed liquid is transferred to oil-water separator 240 via cooler 230 or without passing through cooler 230.

[0030] The oil-water separator 240 separates the condensate into an oil phase and an aqueous phase by gravity, recovering the upper oil phase as aroma oil 105 from a recovery port at the bottom of the oil-water separator 240, and transferring the lower aqueous phase as aroma distilled water 102 to a distillate tank 250, for example, using the siphon principle. The oil-water separator 240 has an overflow structure suitable for continuous operation and a structure that allows the separation state to be visually observed. The oil-water separator 240 may also have an outlet for supplying the oil to the electrolysis device 120 in the production system 100. The distillate tank 250 stores the aroma distilled water 102, which is recovered from a recovery port at the bottom of the distillate tank 250.

[0031] The distillation apparatus 110 is compatible with six distillation methods. The distillation apparatus 110 can perform aroma-coated atmospheric distillation (method 1) and reduced-pressure distillation (method 2), boiling-out atmospheric distillation (method 3) and reduced-pressure distillation (method 4), and live steam injection combined with aroma-coated distillation (method 5) and water-filled still (method 6). The distillation apparatus 110 can select an operating method from the six methods described above depending on the properties of the raw material 101.

[0032] Furthermore, the distillation apparatus 110 is not limited to the above-described configuration. For example, the distillation apparatus 110 may be provided with a viewing window and a level gauge to facilitate operation monitoring. The distillation apparatus 110 may be provided with viewing windows in the distillate tank 250 and the oil-water separator 240, allowing the oil-water interface and the liquid level position to be visually confirmed. The distillation apparatus 110 may employ glass as the material for the level gauge, achieving both visibility and heat resistance. The distillation apparatus 110 may be provided with piping, valves, pressure gauges, thermometers, level gauges, safety valves, and exhaust ports as appropriate.

[0033] The distillation apparatus 110 may also be equipped with a sealed structure and overpressure protection means to ensure safety and maintainability. The distillation apparatus 110 may have all of its operating parts concentrated on the front, with inspection ports and drain ports provided at key locations to facilitate daily operation and maintenance. The distillation apparatus 110 may employ an operating procedure for cleaning its piping by injecting live steam to remove residues without rinsing or disassembly. The distillation apparatus 110 may use stainless steel for the main liquid-contacting parts to prevent corrosion and improve cleanability.

[0034] The distillation apparatus 110 may also be installed as a unit configuration including a boiler and a chiller to accommodate installation and utility requirements. The distillation apparatus 110 can also be applied to environments that do not have a heat source or cooling water equipment, and the boiler system and chiller configuration may be selected depending on the installation conditions. The distillation apparatus 110 may ensure ease of delivery, installation, and relocation by reducing the space required for the piping system and equipment arrangement.

[0035] Furthermore, even if the dimensions, materials, or arrangement of the distillation apparatus 110 are changed, the same operational effects can be achieved as long as the functional relationships shown in FIG. 2 are satisfied.

[0036] 3 is a diagram showing an example of an electrolysis device 120 (commercial configuration). Note that a home configuration will be described in the second embodiment.

[0037] The electrolysis device 120 includes a control device 310, a raw water tank 320, an electrolysis unit 330, a chemical injection tank 340, and a product water tank 350. The electrolysis device 120 receives aromatic distilled water 102 as raw water, and electrolysis is performed in the electrolysis unit 330 using a solution of carbonate electrolytes (e.g., sodium bicarbonate, sodium carbonate, potassium carbonate) held in the chemical injection tank 340 to adjust the conductivity. The electrolyzed water generated on the cathode side is collected in the product water tank 350 as aromatic electrolyzed water 103. The electrolysis device 120 also discharges the liquid generated on the anode side to the outside through a drain pipe. The electrolysis device 120 is configured to hold a carbonate solution in the chemical injection tank 340 and inject it into the raw water line via a dedicated carbonate chemical injection line, which is not shared with other systems. A saltwater tank (optional) for holding salt (NaCl solution, saline solution) may be added as a separate system only when comparative evaluation or correction is required.

[0038] The control device 310 is responsible for starting and stopping operation, selecting the operation mode, setting the electrolytic current, and monitoring the flow rate, conductivity, pH, temperature, and liquid level of each tank. The control device 310 displays the target amount of electrolyte to be added based on the target conductivity value, and issues an alarm and performs a safety shutdown in the event of an abnormality. The control device 310 records the operation history along with time information to ensure quality traceability.

[0039] The raw water tank 320 holds a predetermined amount of aroma distilled water 102 and supplies the raw water to the electrolysis unit 330 via a liquid feed pump. The raw water tank 320 is equipped with a volume scale, a liquid level detector, a removable cover, and a drain port to facilitate replenishment and cleaning. If necessary, a coarse strainer or filter may be inserted in the raw water line of the raw water tank 320 to reduce suspended solids and prevent adhesion to the electrolysis unit 330.

[0040] The electrolysis unit 330 includes electrodes and an electrolytic cell. The electrolysis unit 330 typically has a two-chamber configuration with a diaphragm, which liquid-tightly separates the cathode chamber from the anode chamber. The electrolysis unit 330 directs electrolyzed water from the cathode chamber to the product water tank 350 as aroma electrolyzed water 103, and directs electrolyzed water from the anode chamber to a drain pipe. The electrolysis unit 330 is equipped with a thermometer, a pressure gauge, a conductivity meter, and a gas vent path to stabilize operation and discharge gases. The electrodes of the electrolysis unit 330 are made of corrosion-resistant metal or conductive carbon material and can withstand continuous operation.

[0041] The chemical injection tank 340 holds a carbonate electrolyte solution and injects it into the raw water line in minute amounts via a dedicated carbonate injection line and metering pump. The chemical injection tank 340 is equipped with a volume scale, a refill port, a stirring means, and a circulation means (optional) to suppress precipitation and sedimentation and ensure uniform concentration. Chemical injection is performed via a dedicated injection port and check valve, and a static mixing section downstream enables dilution and mixing over a short distance. The chemical injection concentration is adjusted according to the raw water's conductivity, pH, temperature, etc., aiming for a predetermined range (e.g., 0.01% by mass to 10% by mass). The chemical injection tank 340 system is not shared with the saltwater tank system, and its piping, valves, and instrumentation are separate. If necessary, a drain port, liquid level detection, a filter (pretreatment side), and flushing procedures are provided to prevent cross-contamination and residual precipitates during switching.

[0042] The brine tank holds brine (NaCl solution) and injects it into the raw water line in minute amounts via a metering pump. The brine tank is equipped with a volume scale and a refill port for concentration control, and is configured to safely handle brine of a specified concentration. The brine tank allows for on-off valve control based on instructions from the control device 310 so that injection can be stopped once the target range of conductivity is reached. Note that the brine tank does not contain carbonate solution. Brine injection is carried out on a dedicated line, not shared with the chemical injection tank 340 system, and the injection concentration and flow rate are controlled, and the retention section after injection is designed to be short, in order to prevent the conductivity from exceeding the upper limit and to prevent crystal precipitation and adhesion within the piping.

[0043] The produced water tank 350 receives the aroma electrolyzed water 103 introduced from the cathode side of the electrolysis unit 330 and sends it to the downstream adjustment and blending process 130 or filling and packaging process 140. The produced water tank 350 is connected to the electrolysis unit 330 via a flow path with a check valve to prevent backflow. The produced water tank 350 is equipped with a liquid level detector, a discharge valve, and a sampling port to facilitate quality checks and discharge operations.

[0044] The electrolysis device 120 is appropriately equipped with piping, valves, pressure gauges, thermometers, flow meters, level gauges, safety valves, and gas vent paths. The electrolysis device 120 uses stainless steel or chemical-resistant resin for the main liquid-contacting parts to prevent corrosion under alkaline and saltwater conditions. The electrolysis device 120 is configured to be able to perform cleaning operations using citric acid, rinsing operations, and an automatic drainage sequence for maintenance work.

[0045] In an example operation, the control device 310 supplies raw water from the raw water tank 320 to the electrolysis unit 330 at a constant flow rate, adjusts the conductivity to a target range based on the amount of carbonate electrolyte added from the chemical feed tank 340, and performs electrolysis at a set current. When the saltwater tank system is set to operate, the control device 310 issues a command to inject saltwater if the conductivity drops and stops the injection if the conductivity exceeds the upper limit. The control device 310 periodically opens the gas vent path to promote gas-liquid separation and stabilizes the supply of water to the product water tank 350. An operator measures the pH and conductivity of the electrolyzed aroma water 103 in the product water tank 350 to confirm that they are within the desired range.

[0046] The electrolysis device 120 is not limited to the above-described configuration. The electrolysis device 120 primarily uses a carbonate-based electrolyte as a conductivity adjuster, allowing for the addition of a small amount of sodium chloride solution when comparative evaluation or correction is required. The electrolysis device 120 may also employ a flow-through configuration without a diaphragm, and electrolyzed water preferentially extracted from a flow path near the cathode may be recovered as aroma electrolyzed water 103. Even if the dimensions, materials, or layout of the electrolysis device 120 are changed, the electrolysis device 120 will still achieve the same effects as the previous model, as long as it satisfies the following functional relationships: aroma distilled water 102 is used as raw water, conductivity is adjusted with brine from a brine tank, the cathode-side electrolyzed water is recovered in the product water tank 350, and the anode-side solution is discharged through a drain pipe. The electrolysis device 120 separates the carbonate-based electrolyte chemical injection system from the brine system, and flushes the piping with raw water when switching between operations to prevent cross-contamination and precipitation.

[0047] Figure 4 is a diagram showing an example of the procedure for a distillation process using distillation apparatus 110. The procedure shown in Figure 4 is carried out in the following order: raw material preparation in S401, apparatus preparation in S402, distillation operation in S403, cooling and condensation in S404, oil-water separation in S405, and recovery and temporary storage in S406. Steps S401 to S406 shown in Figure 4 are basic procedures common to both batch and continuous operations.

[0048] <S401: Raw material preparation> An operator receives plant materials such as citrus peels, fruit pulp, coniferous tree branches and leaves, and herbs as raw material 101 and removes any foreign matter. The operator washes, cuts, and crushes the materials as needed to ensure a sufficient contact area in the still 210. A similar pretreatment may also be applied when an operator uses by-product materials such as food processing residues as raw material 101.

[0049] <S402: Equipment preparation> An operator selects an operating mode according to the characteristics of raw material 101. Based on the selection, the operator either charges raw material 101 directly into still 210 or places it in a raw material holder and loads it. The operator starts cooler 230, circulates cooling water to condenser 220, and stabilizes the cooling capacity by setting the flow rate and inlet water temperature. If reduced pressure operation is to be adopted, the operator starts vacuum pump 260 and adjusts the pressure in still 210 and condenser 220 to the specified value. The operator checks the operating status of piping, valves, pressure gauges, thermometers, level gauges, and safety valves, and checks for leaks to complete preparation of the equipment.

[0050] More specifically, the distillation apparatus 110 is compatible with six distillation methods depending on the characteristics of the raw material 101. The distillation apparatus 110 is capable of performing atmospheric distillation (method 1) and reduced pressure distillation (method 2) in the method using aromatic malt. The distillation apparatus 110 is capable of performing atmospheric distillation (method 3) and reduced pressure distillation (method 4) in the boiling distillation. The distillation apparatus 110 is capable of performing live steam injection using aromatic malt (method 5) and water filling of the still pot (method 6) in the live steam injection. The distillation apparatus 110 allows operation to compare extraction conditions between each method.

[0051] In the aromatic macago method (first method and second method), the distillation apparatus 110 is suitable for accepting herbs as the raw material 101. Specific examples of the raw material 101 that can be used with the distillation apparatus 110 include lemongrass, basil, mint, rosemary, thyme, shiso, and lavender. The distillation apparatus 110 can achieve low-temperature extraction (for example, approximately 40°C) that is compatible with the raw material by selecting reduced-pressure conditions in order to preserve the delicate aromatic components contained in the herbs.

[0052] In the decoction distillation methods (the third and fourth methods), the distillation apparatus 110 is suitable for receiving citrus fruits, flowers, and roots and stems as the raw material 101. The distillation apparatus 110 can efficiently volatilize and recover aroma components by heating the citrus peels and petals in contact with an aqueous medium. When it is necessary to suppress the thermal history of the raw material 101, the distillation apparatus 110 can set reduced pressure conditions and select low-temperature extraction.

[0053] In the live steam injection method (method 5 and method 6), distillation apparatus 110 preferably accepts woody materials as raw material 101. Specific examples of the raw material 101 that can be used in distillation apparatus 110 include wood chips, branches and leaves, sawdust, etc. Examples of coniferous materials include cypress leaves and cedar leaves. Operators may also use cypress leaves, cedar leaves, or a mixture thereof as raw material 101. By directly introducing live steam into the woody material, which has poor breathability, distillation apparatus 110 promotes the transfer of aroma components and improves extraction efficiency.

[0054] When selecting an operating method, the operator evaluates the moisture content, hardness, oil vesicle distribution, and particle size of the raw material 101 and selects a candidate method from Methods 1 to 6. The operator conducts small-scale tests of multiple methods and determines the operating conditions based on indicators of aroma retention and recovery amount. After selecting the method, the operator sets the degree of vacuum, heating temperature, cooling water conditions, and supply flow rate in accordance with existing process control items.

[0055] <S403: Distillation operation> An operator starts operation of the distillation apparatus 110. The distillation apparatus 110 heats the jacket with steam supplied from the boiler, raising the temperature of the raw material 101 in the still 210 and generating steam containing aromatic components. The control panel of the distillation apparatus 110 maintains the pressure inside the kettle at near atmospheric pressure during normal pressure operation, and operates the vacuum pump 260 to reduce the pressure inside the kettle during reduced pressure operation, thereby maintaining low-temperature extraction according to the compatibility with the raw material. The distillation apparatus 110 directs the generated steam through the upper piping to the condenser 220. An operator monitors the temperature, pressure, and steam flow rate during operation, and adjusts the steam supply amount and vacuum level if any deviations from the set values ​​are detected.

[0056] <S404: Cooling and condensation> Condenser 220 cools the steam introduced from still 210 through heat exchange and converts it into a condensate containing aroma components. Cooler 230 controls the temperature and flow rate of the cooling water circulating to condenser 220 to maintain condensation efficiency within a specified range. An operator monitors the setting value of cooler 230 and the inlet and outlet temperatures of condenser 220, and fine-tunes the cooling water conditions as necessary.

[0057] <S405: Oil / water separation> The oil-water separator 240 continuously receives condensate and separates the liquid into two phases: an oil phase and an aqueous phase. The oil-water separator 240 recovers the upper oil phase as aroma oil 105, and the lower aqueous phase as aroma distilled water 102. The oil-water separator 240 has an overflow structure to maintain a constant residence time and ensure separation efficiency even when the supply flow rate fluctuates. The oil-water separator 240 may be equipped with a viewing window or a level gauge to allow the position of the oil-water interface to be confirmed, and an operator may adjust the recovery valve and discharge valve based on the interface position to prevent the incorporation of the oil phase. The production system 100 controls the temperature of the condensate as needed, ensuring differences in viscosity and density to improve separation efficiency. If fine emulsions remain, the production system 100 uses a coarse strainer in a subsequent process to reduce suspended solids and stabilize the quality of the aroma distilled water 102.

[0058] <S406: Collection and temporary storage> An operator receives the aroma distilled water 102 in the distillate tank 250 recovered from the oil-water separator 240 into a temporary storage container. The operator closes the lid of the temporary storage container and keeps it sealed. The operator shields the temporary storage container from light and heat to prevent changes in quality until it is time to supply it to the electrolysis device 120. If necessary, the operator passes the aroma distilled water 102 through a coarse strainer to reduce the suspended solids. Prior to temporary storage, the operator measures the pH and conductivity to confirm that they are within the conductivity range suitable for the electrolysis conditions. The operator transfers the aroma oil 105 in the distillate tank 250 recovered from the oil-water separator 240 to a collection container, where it may be stored as a raw material for another product. The operator records the lot number, raw material type, distillation conditions, recovered amount, and measured values ​​in a logbook.

[0059] 4 is performed as a continuous operation, the control panel of the distillation apparatus 110 monitors the liquid levels in the distillate tank 250, the oil-water separator 240, and the temporary storage container, and coordinates the operation of the liquid feed pump and the vacuum pump 260. In continuous operation, an operator sets the heating temperature, degree of vacuum, cooling water temperature, water flow rate through the condenser 220, and supply flow rate to the oil-water separator 240 according to the aroma retention and recovery target. In continuous operation, the control panel of the distillation apparatus 110 maintains the set values ​​while maintaining the process order S401 to S406, thereby achieving both the oil recovery rate of the aroma oil 105 and the aroma retention of the aroma distilled water 102.

[0060] Figure 5 is a diagram showing an example of the procedure for the electrolysis process using the electrolysis device 120. The procedure shown in Figure 5 is carried out in the following order: preparation of raw water and chemical feeding in S501, water quality adjustment and pretreatment in S502, generation in the electrolysis unit in S503, recovery, storage, and sidestream treatment in S504, finishing in S505, and automatic cleaning and maintenance in S506. Each step shown in Figure 5 is functionally linked to the electrolysis device 120, which includes the control device 310, raw water tank 320, electrolysis unit 330, chemical feeding tank 340, and produced water tank 350 shown in Figure 3.

[0061] The production system 100 determines operating conditions based on the premise that aromatic distilled water 102, unlike ordinary water, variably contains at least one of volatile components, trace amounts of oil droplets (oil microdroplets), resin-like components, and dissolved gases. The production system 100 recognizes that these components affect the electrode surface condition and gas generation behavior of the electrolysis unit 330, potentially acting as a detrimental factor to electrolysis stability even when the conductivity is the same. The production system 100 ensures reproducibility of electrolysis through operator-led condition selection in steps S501 to S503. Compared to configurations employing uniform operation without considering detrimental factors, the production system 100 offers the technical significance of stabilizing the quality of aromatic electrolyzed water 103 by adjusting the current, time, flow rate, chemical injection amount, and temperature.

[0062] <S501: Preparation of raw water and chemical injection> An operator prepares raw water in the raw water tank 320. The operator selects aroma distilled water 102 or a mixture of aroma distilled water 102 and purified water as the raw water. The operator checks the origin information based on the six methods of the distillation apparatus 110, the measured conductivity, the measured pH, the measured turbidity, and the presence or absence of residual oil droplets, and determines the initial settings of the electrolysis unit 330 (electrolysis current, electrolysis time, liquid feed flow rate, raw water temperature, injection amount from the chemical injection tank 340, injection amount from the brine tank (optional), and whether or not a diaphragm is used). The aroma distilled water 102 used as raw water may be a mixture of citrus aroma distilled water and coniferous aroma distilled water in a predetermined ratio (e.g., a volume ratio of 5:95 to 95:5). Electrolyzing this mixed raw water can achieve both cleansing properties and odor reduction.

[0063] For example, for low-conductivity, high-volatile matter types obtained by vacuum distillation of aromatic herbs and rhizomes, the operator may set the chemical dosage to a low level, the electrolysis current to a low level, and the flow rate to a low level. For medium-conductivity, fine-oil droplet types obtained by boiling and distilling citrus fruits or flowers, the operator may adjust the chemical dosage to a low level and determine the pre-processing strategy described below. For relatively high-conductivity, resinous-component-containing types obtained by live steam injection of woody materials, the operator may minimize the chemical dosage and set the electrolysis current to a medium level. If the conductivity does not meet the target range, the operator may add sodium bicarbonate or sodium chloride within the specified range.

[0064] For example, if the conductivity does not meet the target range, the operator may add a carbonate-based electrolyte to the raw water within a predetermined range to correct the conductivity. By adding the carbonate-based electrolyte before electrolysis, the operator can quickly raise the conductivity of the raw water to the desired value and reduce the initial voltage rise, current limitation, and excessive load on the electrodes. If the control device 310 detects a fluctuation in conductivity during electrolysis, it drives the metering pump to gradually inject the carbonate-based electrolyte, suppressing excessive gas generation and potential fluctuations and maintaining the stability of the electrolysis. Furthermore, by adding a small amount of carbonate-based electrolyte after electrolysis, the operator can impart pH buffering properties, assisting in neutralization to preserve the aroma and suppressing pH drift during storage.

[0065] <S502: Water quality adjustment / pretreatment> The control device 310 activates the pretreatment unit in the raw water piping. The control device 310 suppresses the inflow of suspended solids through a strainer or filter to prevent foreign matter from entering the electrolysis unit 330. Operators use a coarse strainer on the inlet side of the liquid obtained by the boiling and distillation of citrus fruits or flowers to remove suspended solids. Operators optionally install a coalescer, a cartridge filter of several microns, or an oil-affinity adsorption medium (such as activated carbon or oleophilic fiber) in series to reduce fine emulsions or small oil droplets. The production system 100 exemplifies pretreatment targets of a volumetric particle size D50 of 10 μm or less, a turbidity of 10 FTU or less, and an oil content index of 5 mg / L or less. Operators may add an adsorption-based pretreatment system to liquids originating from live steam injection containing resinous components. The control device 310 adjusts the raw water temperature by heating or cooling, generally maintaining it in the range of 20°C to 40°C. The operator sets the temperature on the low side for low conductivity, high volatile content types, and on the medium side for types containing resin-like components.If air bubbles are found, the operator operates the gas vent valve to remove any stagnant air in the piping.

[0066] <S503: Generation in electrolysis unit> The control device 310 applies current to the electrolysis unit 330 to initiate the electrolysis reaction. The electrolysis unit 330 can be configured with either a cathode chamber and an anode chamber separated by a diaphragm, or without a diaphragm. For example, an operator may prioritize aroma retention for a low-conductivity, high-volatile content type and select a diaphragm configuration as the recommended setting. At the beginning of operation, the operator remeasures the inlet conductivity of the electrolysis unit 330 and fine-tunes the chemical dosage or electrolysis current according to deviations from the target range. The control device 310 monitors the electrolysis current, electrolysis voltage, and flow rate, and corrects the output if any deviations from the set values ​​occur to maintain stable operation.

[0067] <S504: Recovery, storage, and sidestream treatment> The control device 310 introduces the electrolyzed water obtained from the cathode chamber into the produced water tank 350, where it is stored in a sealed state. The control device 310 safely discharges the by-flow discharged from the anode chamber through a drain pipe and connects it to a neutralization or dilution process as necessary. The control device 310 releases gas generated during electrolysis through a gas vent path and prevents liquid from splashing using a check valve. An operator measures the liquid level, pH, and conductivity of the produced water tank 350 and records the results in a logbook.

[0068] <S505: Finishing> The operator adjusts the electrolyzed water in the produced water tank 350 according to the intended use. The operator dilutes, blends, and filters as necessary to adjust properties such as viscosity, aroma, and pH to the desired range. The operator may limit the purpose of filtration to removing solid foreign matter or for sanitation control, and may not employ a filtration process aimed at removing oil. The operator transfers the water to a container in a sanitary environment during filling, sealing it, and identifying it. The operator may also add trace amounts of inorganic salts or plant essential oils. The operator may perform a blending process that preserves the aroma notes of the citrus aroma distilled water 102 while imparting the deodorizing benefits of the coniferous aroma distilled water 102. For example, the operator may blend citrus-derived electrolyzed water with coniferous-derived electrolyzed water to develop an aroma note and improve the deodorizing index. The operator measures and records the blend ratio, pH, and conductivity to prepare for reproduction.

[0069] <S506: Automatic cleaning and maintenance> After stopping electrolysis, the control device 310 flushes the pipes with raw water to prevent remixing and deposition of residual liquid. The control device 310 has an acid cleaning sequence as a maintenance mode, which circulates a cleaning solution such as citric acid to dissolve and remove scale. After cleaning is complete, the control device 310 performs a thorough rinse and confirms that the conductivity has returned to the standard value. Operators inspect the filters, valves, and sensors, and replace consumable parts as necessary. Safety features may be omitted or added depending on the application and installation environment.

[0070] The production system 100 electrolyzes aroma distilled water 102 obtained by steam distillation of plant materials to produce aroma electrolyzed water 103. The production system 100 supplies aroma distilled water 102 as raw water to the electrolysis device 120, and adds a carbonate electrolyte within a predetermined range if necessary to adjust the conductivity. The production system 100 may be configured to add a trace amount of sodium chloride for comparative purposes, or may be limited to conditions where the available chlorine is below the lower limit of measurement. The electrolysis device 120 is operated continuously or batchwise and may be configured with or without a diaphragm, and the electrolyzed water obtained at the cathode side is recovered as aroma electrolyzed water 103. The production system 100 provides equivalent operational effects even if the dimensions, materials, and layout of the device are changed as long as the described functional relationships are met.

[0071] The electrolysis device 120 can add a carbonate electrolyte within a predetermined range when conductivity adjustment is required. When injecting a carbonate electrolyte, the electrolysis device 120 uses a chemical injection tank 340 and a dedicated injection port, rather than sharing the chemical injection line with the brine tank. By selecting the carbonate species and setting the amount to be added, the electrolysis device 120 can adjust the balance between the target pH range, the tendency for electrode surface contamination, the storage stability of the product solution, and the prevention of contamination with available chlorine.

[0072] The manufacturing system 100 can set the use of the product 104 to surface cleaning and surface deodorization, as well as surface sterilization, surface antibacterial treatment, and surface virus inactivation. The manufacturing system 100 targets at least one of metal, resin, glass, ceramic, and fiber surfaces, and applies by spraying, wiping, or immersion. The manufacturing system 100 manages application conditions such as liquid volume, contact time, pH, conductivity, and temperature, and ensures traceability of reproduced manufacturing by correlating manufacturing records with application records. The manufacturing system 100 works in conjunction with labeling in the filling and packaging process 140 to select the use label item from cleaning, deodorization, sterilization, antibacterial treatment, and virus inactivation.

[0073] The electrolysis device 120 uses manual settings as the basis for operational settings, but as a variant, has an automatic recommendation function that uses setting profiles. The electrolysis device 120 receives distillation method records, conductivity, pH, turbidity, and simple absorbance as inputs, and recommends setting profiles corresponding to either low conductivity / high volatile content type, medium conductivity / fine oil droplet type, or high conductivity / resinous component type. The electrolysis device 120 is designed for operation in which an operator can confirm the recommended settings and overwrite them as necessary. The manufacturing system 100 does not limit the number of setting profiles, thresholds, switching conditions, or recommended pretreatments.

[0074] The evaluator will carry out evaluation example E1 (removal of oily stains). The evaluator will prepare a contaminated board standardized with cooking oil, spray a predetermined amount of aromatic electrolyzed water on it, leave it to stand for a certain period of time, and then mechanically scrub it. For comparison, the evaluator will use aromatic distilled water and purified water without pretreatment, quantify the residue after scrubbing using a mass method or image analysis, and calculate the removal rate.

The evaluator will prepare Sample A (aroma electrolyzed water obtained by electrolyzing aromatic distilled water), Sample B (electrolyzed water obtained by electrolyzing purified water), and Sample C (a sample in which plant essential oils have been added to electrolyzed water obtained by electrolyzing purified water). The evaluator will inoculate a standardized bacterial solution onto a contaminated carrier and dry it, then spray a fixed amount of each sample onto the carrier for a contact time of 30, 60, or 300 seconds. After recovery, the evaluator will culture the samples, quantify the number of surviving bacteria, calculate the logarithmic reduction (log reduction) relative to the initial number of bacteria, and compare the effectiveness of each sample.

[0081] The evaluator will conduct Evaluation Example E8 (wiping cleaning in a water outage environment). The evaluator will evaluate the oil stain removal and odor reduction properties of the wiping operation after spraying, with the aim of verifying the applicability of surface cleaning in a water outage environment or an outdoor environment.

[0082] The evaluator will conduct Evaluation Example E9 (Dilution Effect). The evaluator will prepare Sample A (a concentrate of aromatic electrolyzed water obtained by electrolyzing aromatic distilled water) and Sample A-10, which is obtained by diluting Sample A approximately 10 times. To verify cleaning applications, the evaluator will conduct tests using the same substrate, contamination conditions, spray volume, and contact time in accordance with the procedures of Evaluation Example E1, and calculate the grease removal rate. To verify deodorizing applications, the evaluator will conduct tests using the same closed space conditions, spray volume, and contact time in accordance with the procedures of Evaluation Example E2, and calculate the odor reduction rate. The evaluator will record the pH, conductivity, liquid temperature, and interfacial tension for each test and record them in a logbook. The evaluator will confirm that Sample A-10 is non-inferior to Sample A within the tolerances in each of the cleaning and deodorizing applications tests, and that there is little decline in the grease removal rate and odor reduction rate. As a reference for microorganism-related applications, the evaluator will follow the procedures of Evaluation Examples E5 to E7, set conditions for Sample A-10 with an increased contact time, and confirm the maintainability of the log reduction value.

[0083] The evaluator will measure the pH, conductivity, temperature, and aroma of each of Samples A, B, and C in advance and record the measured values ​​in a record book.

[0084] The evaluator applies a standardized staining liquid containing cooking oil and food residue evenly to a substrate selected from ceramic dishes, synthetic resin plates, and metal plates, and leaves it to stand at room temperature for a certain period of time to create an oil-stained surface.The evaluator uses stains that adhere after eating curry and oil that adheres after cooking grilled fish as stain types, and controls the amount of adhesion using the mass method.

[0085] The evaluator sprays each sample onto the contaminated surface. The evaluator sprays the amount of each sample at a rate of 0.5 mL to 2.0 mL / 100 cm. 2 The contact time is set within a range of 15 to 120 seconds. After contact, the evaluator uses a paper wiper to wipe a certain number of times, selecting the number of wipes from 1, 3, or 5. The evaluator keeps the wiping direction, load, and speed constant and records the operation conditions in a logbook.

[0086] The evaluator calculates the oil stain removal rate using the mass difference method before and after rubbing or image analysis. The evaluator measures the odor intensity on a scale using a sensory evaluation method, and complements the measurement results by obtaining the relative change amount using a simple gas sensor. The evaluator evaluates the surface wetting spread by measuring the contact angle or measuring the spread diameter over time, and records an index of initial wetting. The evaluator confirms the residual feel of the surface after treatment by tactile evaluation and gloss measurement.

[0087] The evaluator records the material, type of dirt, spray amount, contact time, number of wipes, pH, conductivity, liquid temperature, measurement time, and operator in a logbook. The evaluator performs repeated measurements with three or more independent replicates and organizes the average values ​​and variance.

[0088] The evaluator will record the sample lot number, raw material type, distillation method, electrolysis conditions, storage conditions, whether or not a solubilizer was used, and the amount of solubilizer used (if applicable to sample C) in the logbook. The evaluator will observe the spray nozzle specifications, spray pattern, and whether or not there is clogging, and record any operational issues.

[0089] The assessor will take splash control measures during spraying and wiping to minimize inhalation and skin exposure. The assessor will collect and properly dispose of paper wipes and contaminated plates.

[0090] Based on the results of evaluation examples E1 through E9, the manufacturing system 100 optimizes the electrolysis and formulation conditions, achieving surface disinfection, antibacterial, and virus inactivation effects while maintaining surface cleaning and deodorizing effects. The manufacturing system 100 incorporates the actual log reduction values ​​obtained in the evaluation into the description of the effects, clarifying the superiority of the product over samples B and C. Based on the non-inferiority of the approximately 10x dilution conditions for cleaning and deodorizing purposes confirmed in evaluation example E9, the manufacturing system 100 can adopt an operation format of concentrated supply and dilution at the time of use. The manufacturing system 100 stores the optimized application conditions, formulation ratios, and measurement values ​​as manufacturing records for use in replicating manufacturing and quality assurance.

[0091] As a form of application expansion, the manufacturing system 100 employs a mixture of citrus-derived electrolyzed aroma water and conifer-derived electrolyzed aroma water, aiming for a synergistic effect of adjusting the fragrance tone and reducing odor. The manufacturing system 100 measures and records the mixture ratio, pH, and conductivity, and correlates them with indicators for cleaning, deodorizing, disinfecting, antibacterial, and virus inactivation applications.

[0092] The production system 100 ensures the stability of electrolysis by removing suspended solids using a coarse strainer as a pretreatment and reducing minute oil droplets using a coalescer, a cartridge filter of several microns, or an oil-affinity adsorption medium. The production system 100 uses turbidity, oil content index, and particle size distribution as pretreatment control indicators, and controls, for example, turbidity to 10 FTU or less, oil content index to 5 mg / L or less, and volumetric particle size D50 to 10 μm or less. The production system 100 maintains the raw water temperature in the range of 20°C to 40°C and degassing if air bubbles are detected, thereby maintaining the operational stability of the electrolysis device 120.

[0093] From the perspective of safety and maintenance, the manufacturing system 100 flushes the pipes with raw water after stopping electrolysis and employs an acid cleaning sequence as a maintenance mode to remove scale. After cleaning is complete, the manufacturing system 100 performs a thorough rinse and confirms that the conductivity has returned to the standard value. The manufacturing system 100 records the inspection results of the filters, valves, and sensors and replaces consumable parts as necessary.

[0094] The manufacturing system 100 combines the evaluation results, application results, and manufacturing records to determine the labeling content for surface cleaning, surface deodorization, surface sterilization, surface antibacterial, and surface virus inactivation applications, and links it to the filling and packaging process 140. The manufacturing system 100 matches the labeling content with the application conditions and maintains control standards to ensure reproducibility for each application. Based on the results of evaluation example E9, the manufacturing system 100 defines the labeling for concentrated supply and dilution at the time of use for each application, and includes the recommended dilution rate and contact time in the labeling items.

[0095] The manufacturing system 100 recognizes fluctuations in electrolytic stability due to variations in raw materials as an inhibiting factor and ensures reproducibility through coordinated management of conductivity, temperature, current, flow rate, and chemical injection amount. The manufacturing system 100 presents operating conditions that achieve both aroma retention and microbial effects in the presence of inhibiting factors, and the results of evaluation examples E1 to E9 support its effectiveness.

[0096] As a quality assurance framework, the manufacturing system 100 centrally manages the raw material type, distillation method, electrolysis conditions, application conditions, measurement values, and evaluation results as lot information. The manufacturing system 100 uses the lot information to promptly implement corrective and preventive measures and ensure the consistency of the product 104.

[0097] In operational change management, the manufacturing system 100 records changes to equipment specifications, formulation conditions, and application conditions, and compares evaluation results before and after the change to verify homogeneity. If the homogeneity verification is not satisfied, the manufacturing system 100 reverts or reoptimizes the conditions.

[0098] By implementing the described processes, conditions, and evaluation procedures, the production system 100 produces aromatic electrolyzed water 103 with resource recycling properties while simultaneously achieving application suitability for surface cleaning, surface deodorization, surface sterilization, surface antibacterial properties, and surface viral inactivation. By achieving these application suitability, the production system 100 provides a versatile liquid composition for home and commercial environments.

[0099] Furthermore, in a test in which the aroma electrolyzed water 103 obtained by this embodiment was stored at room temperature, no significant deterioration was observed in the appearance (turbidity, precipitation, coloration) or sensory evaluation of the aroma up to approximately 15 months after the start of storage, and no signs suggesting microbiological deterioration (off-flavor, container swelling, gas generation) were observed within the scope of the test. Note that this description is a report of actual measurement results under specific conditions, and does not guarantee quality maintenance regardless of differences in storage conditions, raw material types, containers, etc.

[0100] In this embodiment, the production system 100 uses aroma distilled water 102, a by-product, as a raw material, thereby reducing waste and promoting resource recycling. The production system 100 is compatible with operations based on food processing residues and forestry by-products, contributing to the enhancement of the value of local materials. The production system 100 uses aroma distilled water 102 as raw water. The fine bubbles and electric field generated during the electrolysis process uniformly disperse water-soluble aroma components and fine oil droplets, appropriately reducing surface tension. The uniform dispersion and reduced surface tension of the production system 100 promote wetting and interfacial penetration onto the treated surface, thereby improving the initial efficiency of cleaning, deodorizing, and sanitizing treatments. Technically, the production system 100 differs from methods that add plant essential oils to the purified water electrolyte afterward. By homogenizing aroma components during the electrolysis process, regardless of whether surfactants are added, it enables operation that is more likely to reduce component separation, uneven spraying, and nozzle clogging. The manufacturing system 100 coordinates the control of conductivity, temperature, current, flow rate, and chemical dosage to prevent contamination of the electrode surface and reaction instability, ensuring operational reproducibility. The manufacturing system 100 optimizes the application conditions of liquid volume, contact time, pH, conductivity, and temperature to ensure a balance between effectiveness and reproducibility for multiple applications.

[0101] (II) Second embodiment The second embodiment relates to a home-use configuration of the electrolysis device 120. This second embodiment is used in combination with the process configuration of the manufacturing system 100 and the configuration of the distillation device 110 described in the first embodiment, and is characterized by a tabletop housing, batch operation, and raw water volume adjustment using water level gauges in the left and right water chambers to suit small-scale production. The second embodiment is based on a configuration in which electrolyzed water generated on the cathode side is used as the aroma electrolyzed water 103, and a configuration in which the liquid on the anode side is led to a discharge system. The second embodiment is intended to maintain the aroma electrolyzed water 103 in a range that is substantially free of available chlorine (FAC) (for example, below the lower limit of detection or 0.1 ppm or less).

[0102] FIG. 6 is a diagram illustrating an example of an electrolysis device 120 (home use configuration).

[0103] The electrolysis device 120 includes a power supply unit 610, an operation unit 620, an input unit 630, a raw water container 640, an electrolysis unit 650, and a discharge unit 660. The electrolysis device 120 (e.g., the operation unit 620) includes a control unit for various control functions. The electrolysis device 120 accommodates each component in a cabinet suitable for tabletop installation. The electrolysis device 120 receives aroma distilled water 102 as raw water and discharges electrolyzed water generated on the cathode side as aroma electrolyzed water 103 from the discharge unit 660. The electrolysis device 120 operates primarily in batch mode, with an exemplary operation time of approximately 10 minutes per batch. The electrolysis device 120 adjusts the amount of raw water using water level gauges in the left and right water chambers, allowing an exemplary operation in which a total of approximately 5 liters of raw water is input. The electrolysis device 120 may include a detachable tray directly below the discharge unit 660 to prevent dripping. The electrolysis device 120 may have ventilation slits on the top surface of the housing to passively dissipate gas and heat accumulating inside the housing.

[0104] The power supply unit 610 receives 100 V AC power, generates DC power using a rectifier circuit, and supplies it to the control unit and electrolysis unit 650. The power supply unit 610 is equipped with overcurrent protection, temperature protection, and short-circuit protection, and stabilizes the output when the electrolysis current fluctuates.

[0105] The operation unit 620 is responsible for starting and stopping operation, selecting the operation mode, setting the electrolysis current, setting the electrolysis time, and displaying the operating status. The operation unit 620 is composed of a display window and multiple push-button switches, and may have a waterproof structure. The operation unit 620 may also accept automatic setting of the upper limit of the electrolysis current based on the input or measured value of the conductivity.

[0106] The input part 630 is an opening for injecting raw water into the raw water container 640, and is provided with a screw-type lid and elastic packing, and may also be provided with a simple strainer and a backflow prevention mechanism.

[0107] The raw water container 640 holds a predetermined amount of aroma distilled water 102 and supplies it to the electrolysis unit 650 using a built-in pump or gravity. The raw water container 640 has a cylindrical inner surface to prevent residue buildup and is removable for cleaning. The raw water container 640 may be equipped with a translucent material, volumetric markings, and / or gripping ribs. When the conductivity is low, the operator can use a sodium bicarbonate solution (commonly known as baking soda) containing sodium bicarbonate dissolved within a predetermined range as raw water and inject it evenly into the left and right water chambers to adjust the conductivity and pH to a range suitable for electrolysis. Alternatively, the operator may use a small amount of sodium chloride solution to correct the conductivity. However, the operator must select the blending amount and operating conditions so that effective chlorine in the aroma electrolyzed water 103 is not substantially generated.

[0108] When the conductivity is low, the operator may select raw water containing a carbonate electrolyte, such as water with dissolved sodium bicarbonate, and input it into the electrolysis unit 650. By using raw water containing a carbonate electrolyte, the operator can impart alkalinity and buffering ability while suppressing the generation of available chlorine, thereby suppressing pH fluctuations during domestic operation and preserving the fragrance tone.

[0109] The electrolysis unit 650 includes electrodes and an electrolytic cell. The electrolysis unit 650 typically has a two-chamber configuration with a diaphragm, which separates the cathode chamber and the anode chamber in a liquid-tight manner. The electrolysis unit 650 directs electrolyzed water from the cathode chamber to the outlet 660 as aroma electrolyzed water 103 and discharges electrolyzed water from the anode chamber to the outside through a drain pipe. The electrolysis unit 650 may also employ a flow-through configuration without a diaphragm, or may preferentially extract electrolyzed water from a flow path near the cathode and recover it as aroma electrolyzed water 103. The electrolysis unit 650 may optimize the selection of the diaphragm and the position of the flow path to prevent contamination of the aroma electrolyzed water 103 with available chlorine. The electrodes of the electrolysis unit 650 are made of a corrosion-resistant metal or conductive carbon material and can withstand repeated operation. The electrolysis unit 650 may also be equipped with a temperature detector or a conductivity sensor.

[0110] The discharge unit 660 is a discharge port that communicates with the cathode chamber of the electrolysis unit 650, and may include a check valve, a drip prevention feature, and a feature for guiding water to an external container. The internal flow path within the housing communicates between the raw water container 640, the electrolysis unit 650, and the discharge unit 660, and is made of an alkali-resistant resin material.

[0111] The electrolysis device 120 uses a control unit to control the electrolysis current, electrolysis voltage, and electrolysis time. The control unit uses batch operation as the standard, and at the end of operation, discharges a predetermined amount of aroma electrolyzed water 103 from the discharge unit 660 and performs drainage control to prevent backflow of residual liquid. The control unit may automatically set an upper limit for the electrolysis current based on the input value of conductivity. The control unit may also be equipped with a citric acid cleaning mode and an automatic drainage sequence for maintenance purposes. The electrolysis device 120 performs repeated batch operation according to demand, making it suitable for small-scale production for home use.

[0112] The electrolysis device 120 is equipped with a gas vent path for gas management. The gas vent path safely dissipates gas generated in the electrolysis reaction through ventilation slits on the top surface of the housing, and a check valve prevents liquid from splashing. The electrolysis device 120 is equipped with a leakage breaker function, an overpressure protection valve, and a liquid level detector to prevent damage due to dry operation and overpressurization. Safety functions may be omitted or added depending on the application and installation environment.

[0113] To facilitate cleaning and maintenance, the electrolysis device 120 is configured so that the input unit 630, raw water container 640, and discharge unit 660 can be attached and detached without tools. The electrolysis device 120 uses stainless steel or chemical-resistant resin for the main liquid-contacting parts to prevent corrosion under alkaline conditions. The electrolysis device 120 may also use quick connectors for the connections. Even if the external dimensions, container capacity, electrode material, and flow path material are changed, the electrolysis device 120 will achieve the same effects as the previous model, as long as the functional relationship of using aroma distilled water 102 as raw water, recovering cathode-side electrolyzed water as aroma electrolyzed water 103, and discharging anode-side liquid is satisfied.

[0114] In an example operation, an operator injects aroma distilled water 102 into the raw water container 640 through the input unit 630 and adds sodium bicarbonate within a predetermined range as needed. The control unit applies a current ranging from 1 ampere to 5 amperes to the electrolysis unit 650, performing electrolysis for approximately 10 minutes. After electrolysis is complete, aroma electrolyzed water 103 is discharged from the discharge unit 660, and the operator transfers it to a container for household cleaning or deodorization. If necessary, the operator may add plant essential oils to the aroma electrolyzed water 103 after electrolysis and, if necessary, use a small amount of a natural solubilizer to adjust dispersion stability. The operator may also add a small amount of sodium bicarbonate after electrolysis to perform final adjustments for pH buffering or deodorization. If continuous generation is required, the electrolysis device 120 may monitor the remaining amount in the raw water container 640 and perform repeated batch operation, automatically stopping operation when the remaining amount falls below a lower limit. The operation unit 620 may display the remaining time and provide a notification of completion. The above configuration can be modified as appropriate depending on the application and installation conditions, and is not limited to the elements described.

[0115] The control unit discharges the aroma electrolyzed water 103 from the discharge unit 660 after electrolysis is complete. The operator can select the timing of carbonate electrolyte addition: before, during, or after electrolysis. When adding during electrolysis, the operator uses a chemical injection port installed in the piping between the raw water container 640 and the electrolysis unit 650 to perform microinjection using a manual metering mechanism (syringe-type or simple peristaltic mechanism). The piping system is equipped with a check valve, a keying shape, and a content display to prevent erroneous injection. The injection point is immediately before the inlet of the electrolysis unit 650, and homogenization is achieved through a short-distance mixing unit. The control unit is equipped with a safety interlock that tracks the actual conductivity value and indicates whether injection is possible, and issues a warning if excessive injection is performed. Selecting pre-electrolysis addition shortens start-up time and achieves initial stabilization. Selecting post-electrolysis addition allows the operator to perform final adjustments for pH buffering and odor reduction according to the application.

[0116] Fig. 7 is a diagram showing an example of the procedure of the electrolysis process using the electrolysis device 120 according to the second embodiment. The procedure shown in Fig. 7 is carried out in the following order: preparation of raw water in S701, preparation of the device in S702, execution of electrolysis in S703, recovery and storage in S704, and finishing in S705.

[0117] <S701: Preparation of raw water> An operator pours aroma distilled water 102 into the raw water container 640 from the feed port 630. If the conductivity is low, the operator may use sodium bicarbonate water in which sodium bicarbonate has been dissolved within a predetermined range as raw water to adjust the conductivity and pH. When using a two-chamber electrolysis unit 650, the operator refers to the water level gauges in the left and right water chambers to adjust the amount of raw water. The operator records the type of raw water, the amount fed, the conductivity, pH, and the time of feeding, ensuring traceability of the operating conditions.

[0118] <S702: Equipment Preparation> The operator turns on the power supply unit 610 and sets the operation mode, electrolysis current, and electrolysis time on the operation unit 620. The operator places the external container directly below the discharge unit 660 and checks that the check valve is operating. The operator checks the open state of the gas vent path and vents gas from the internal flow path as necessary. The operator checks the sealing state of the lid of the raw water container 640 and confirms that there are no leaks.

[0119] <S703: Electrolysis> The control unit applies a current ranging from 1 ampere to 5 amperes to the electrolysis unit 650, and batch operation is performed for approximately 10 minutes. The control unit monitors the electrolysis voltage and current, and when they reach their upper limits, it controls and stabilizes the output. A gas vent path safely dissipates gas generated by the electrolysis reaction, and a check valve prevents liquid from splashing. When the electrolysis unit 650 is configured with a diaphragm, the cathode chamber and anode chamber are liquid-tightly separated, and electrolyzed water on the cathode side is produced as aromatic electrolyzed water 103. When the electrolysis unit 650 is configured without a diaphragm, electrolyzed water preferentially extracted from the flow path near the cathode is treated as aromatic electrolyzed water 103.

[0120] <S704: Recovery and Preservation> After operation is completed, the control unit discharges a predetermined amount of aroma electrolyzed water 103 from the discharge unit 660, and performs drainage control to prevent the backflow of residual liquid. The operator tightly seals the collected aroma electrolyzed water 103 in an external container and stores it away from sunlight and heat. The operator measures the pH and conductivity as needed to confirm that they are within the desired range. The operator sets the storage period according to the intended use and avoids long-term storage.

[0121] <S705: Finishing> The worker dilutes, mixes, or fills the water depending on the application. When using it for household cleaning or deodorizing purposes, the worker transfers it to a container with a volume measurement and displays instructions for use. If necessary, the worker may add plant essential oils to the aroma electrolyzed water 103 after electrolysis, and if necessary, may use a small amount of a naturally derived solubilizer to adjust the dispersion stability. When repeated batch operation is required, the electrolysis device 120 monitors the remaining amount in the raw water container 640 and automatically stops operation when the remaining amount falls below a lower limit.

[0122] The second embodiment is not limited to the above-described procedure. The electrolysis device 120 may also include features such as automatic conductivity measurement, a citric acid cleaning mode, a remaining time display, a completion notification, and a removable tray directly below the discharge port 660. Even if the settings, piping materials, electrode materials, and container capacity of the electrolysis device 120 are changed, the same effects can be achieved as long as the functional relationship of using aroma distilled water 102 as raw water, recovering electrolyzed water generated on the cathode side as aroma electrolyzed water 103, and discharging the liquid on the anode side is satisfied.

[0123] Alternatively, the production system 100 may add sodium chloride to the aroma distilled water in a conductivity correction amount and recover the cathode-side electrolyzed water as a strongly alkaline cleaning solution using diaphragm-type electrolysis. To prevent the incorporation of available chlorine, the production system 100 uses a diaphragm to liquid-tightly separate the anode chamber and cathode chamber, prioritizes the extraction from the cathode side, and continuously discharges the anode-side solution. The production system 100 maintains the cathode-side extraction flow rate higher than the anode-side discharge flow rate by controlling the flow rate ratio, and sets the cathode-side extraction position near the diaphragm. The production system 100 maintains low pressure on the cathode side to suppress diffusion and migration from the anode side. The production system 100 minimizes the effects of hypochlorite generation and migration by controlling the upper limit of current density, shortening the anode-side residence time, and ensuring top gas venting. The production system 100 limits the strongly alkaline operation mode to pretreatment applications for heavy oil and grease stains, and uses the standard operation mode for applications requiring the preservation of fragrance notes.

[0124] In this embodiment, the production system 100 uses the by-product aroma distilled water 102 as a raw material, thereby achieving both a reduction in waste and the promotion of resource circulation. The production system 100 is suitable for operations based on food processing residues and forestry by-products, and contributes to increasing the value of local materials.

[0125] Furthermore, according to this embodiment, small-scale production can be carried out using a tabletop casing and batch operation, and the aroma electrolyzed water 103 can be supplied immediately after production according to demand. The production system 100 reduces the burden of the storage process and suppresses fluctuations in the aroma over time.

[0126] Furthermore, the electrolysis device 120 operates using aroma distilled water 102 as raw water, and the fine bubbles and electric field action during electrolysis homogenize the dispersion of water-soluble aromatic components and fine oil droplets. The electrolysis device 120 accelerates wetting and spreading on the treated surface under small-volume spray conditions, improving the initial response of cleaning and odor reduction.

[0127] (III) Supplementary Note The identifiers of components described in this specification (e.g., prefixes and symbols such as "first" and "second") are for convenience of identification and do not limit the number, order, function, or arrangement of the components. The same identifier may refer to different components in different embodiments, and one component may also perform the function of another component. Therefore, the identifiers of components described in this specification are not intended to limit the technical scope, functional scope, or scope of rights of the components, and each component should be interpreted flexibly according to the context of the embodiment.

[0128] The manufacturing system 100 refers to a collection of a distillation apparatus 110, an electrolysis apparatus 120, and piping and instrumentation elements connecting the two apparatuses. The manufacturing system 100 can be configured as either a single facility or a multiple facility linkage configuration.

[0129] The above-described embodiment has the following features, for example.

[0130] (1) The method for producing aroma electrolyzed water (e.g., aroma electrolyzed water 103) includes a step of supplying aroma distilled water (e.g., aroma distilled water 102) obtained by distilling (e.g., distillation apparatus 110) a plant raw material (e.g., raw material 101) as water to be electrolyzed (e.g., raw water) to an electrolytic cell (e.g., electrolysis device 120, electrolysis unit 330, etc.) for electrolysis (e.g., S503: production in electrolysis unit), and a step of recovering alkaline aroma electrolyzed water from the electrolytic cell (e.g., S504: recovery, storage, and sidestream treatment).

[0131] According to the above configuration, for example, by supplying aroma distilled water obtained by distilling plant materials to an electrolytic cell as the electrolyzed water, alkaline aroma electrolyzed water can be obtained stably while simplifying the process. Furthermore, for example, aroma distilled water contains aromatic components and water-soluble components derived from plant materials, and after electrolysis in an electrolytic cell, the aroma electrolyzed water is provided as water that exhibits alkaline properties while retaining some of the aromatic components. Furthermore, for example, alkalinity contributes to the saponification of grease stains and the neutralization of acidic odors, so aroma electrolyzed water contributes to improved cleaning and deodorizing properties. Furthermore, for example, aromatic components enhance odor acceptance during use, so aroma electrolyzed water improves comfort in home and commercial environments. Furthermore, for example, the use of aroma distilled water reduces the need for additional components to impart fragrance, allowing aroma electrolyzed water to achieve a simpler composition by reducing the number of additives. Furthermore, for example, aroma distilled water may contain soluble components derived from plants compared to pure water, so the production of aroma electrolyzed water may contribute to ensuring electrical conductivity. Furthermore, for example, the use of aroma distilled water as the water to be electrolyzed reduces the amount of dilution water added and the need for a separate process for adding aroma, so the production of aroma electrolyzed water contributes to simplifying equipment operation and shortening production time. Furthermore, for example, the origin of aroma distilled water is plant-based, which leads to the effective use of resources, so the supply of aroma electrolyzed water contributes to operations that are compatible with reducing environmental impact.

[0132] (2) The above plant ingredients include herbs (lemongrass, citronella, palmarosa, rosemary, thyme, sage, etc.), flowers (rose, jasmine, neroli, chamomile, lavender, geranium, etc.), leaves (peppermint, eucalyptus, bay leaf, tea tree, lemon balm, shiso, etc.), stems (lemongrass stems, mint stems, etc.), branches (cedar branches, cypress branches, etc.), wood (cypress, cedar, hiba, sandalwood, etc.), bark (hiba, camphor, cinnamon, cinnamon, etc.). at least one of the following: roots (vetiver, ginger, etc.), rhizomes (turmeric, ginger, garlic, galangal, etc.), seeds (coriander, fennel, cardamom, anise, etc.), fruits (juniper berries, citrus fruits, etc.), peels (orange, lemon, yuzu, lime, etc.), fruit pulp (citrus fruit pulp, etc.), resins (frankincense, myrrh, benzoin, etc.), or by-products (tea manufacturing residues, fruit processing residues, tree prunings, wood processing by-products, etc.).

[0133] According to the above configuration, for example, plant materials can be selected from herbs, flowers, leaves, stems, branches, wood, bark, roots, rhizomes, seeds, fruits, peels, fruit pulp, resins, or by-products, thereby expanding the range of components in aroma distilled water, and the method for producing electrolyzed aroma water can select materials that easily maintain the aroma tone and impart alkalinity after electrolysis.Furthermore, for example, the freedom in material selection makes it possible to select aroma distilled water with suitable conductivity and organic acid composition, so the method for producing electrolyzed aroma water can improve the reproducibility of current flow behavior in the electrolytic cell and stabilize the achievement of the target pH.

[0134] (3) The aromatic distilled water is a method for producing aromatic electrolyzed water, which is a mixture of aromatic distilled water from citrus fruits (Satsuma mandarin, yuzu, kabosu, sudachi, lemon, lime, orange, grapefruit, pomelo, hassaku, iyokan, ponkan, bitter orange, shikuwasa, bergamot, etc.) and aromatic distilled water from coniferous trees (cedar, cypress, sawara, asunaro, hiba, fir, spruce, Japanese larches, spruce, hemlock, tsuga, kanzashi, black pine, larch, Japanese cedar, etc.) in a predetermined ratio (for example, a volume ratio of 5:95 to 95:5).

[0135] According to the above configuration, for example, the mixed configuration can adjust the ratio of aldehydes and terpene alcohols commonly contained in citrus aroma distillates to terpene alcohols and esters commonly contained in coniferous aroma distillates, thereby reducing the relative amounts of components that are easily degraded under alkaline conditions and improving aroma retention after electrolysis. Furthermore, for example, the mixed configuration can complement the fast-onset citrus-derived aroma notes and the long-lasting coniferous-derived aroma notes over time, thereby providing electrolyzed aroma water with a consistent aroma perception from immediately after use to after use. Furthermore, for example, the mixed configuration can level out the concentration deviations of micro-oil droplets and hydrophilic components inherent in each aroma distillate, thereby suppressing foaming and local decomposition of aroma components during electrolysis and improving the reproducibility of electrolysis behavior.

[0136] (4) The plant raw materials are food processing residues (for example, fruit processing residues, tea manufacturing residues, etc.) or forestry by-products (for example, tree prunings, bark, wood processing by-products, etc.).

[0137] According to the above configuration, for example, food processing residues or forestry by-products are used as plant raw materials, so the production of aromatic electrolyzed water can achieve both reduced raw material costs and reduced waste. Furthermore, for example, the use of food processing residues or forestry by-products can mitigate seasonal fluctuations in raw material supply by utilizing a secondary resource that is continuously generated in the region, so the production of aromatic electrolyzed water can maintain high levels of quality control of the electrolyzed water and stable continuous operation. Furthermore, for example, the use of locally-sourced food processing residues or forestry by-products as plant raw materials makes it possible to obtain aromatic distilled water with fragrances that reflect the region's unique vegetation and food culture, so the provision of aromatic electrolyzed water is directly linked to the creation of specialty products that highlight the region's unique characteristics.

[0138] (5) This process includes processes (e.g., setting change operations in S501, S503, and S703) for changing electrolysis settings (e.g., electrolysis current setting, electrolysis time setting, operation mode selection) according to the type of aroma distilled water. Typical types of aroma distilled water, based on plant origin, include citrus fruits, conifers, herbs, flowers, bark and wood, roots and rhizomes, seeds and fruits, resins, and by-products. Based on process, there are aroma macao atmospheric and vacuum distillation, boiling atmospheric and vacuum distillation, and live steam injection. Based on properties, there are low conductivity and high volatile matter, medium conductivity and fine oil droplets, and high conductivity and resinous components. Mixed types include a specified ratio of citrus fruits and conifers.

[0139] According to the above configuration, for example, by adopting a process of changing the electrolysis settings depending on the type of aroma distilled water, the conductivity and buffering properties that differ for each raw material can be corrected during production, allowing the recovery of aroma electrolyzed water to maintain a high level of reproducibility of the target alkalinity.Furthermore, for example, by adjusting the current density and current flow time depending on the type of aroma distilled water, excessive decomposition of aromatic components can be suppressed, allowing the provision of aroma electrolyzed water to achieve both the preservation of fragrance notes and functionality.

[0140] (6) The method includes adding a carbonate-based electrolyte (sodium bicarbonate, sodium carbonate, potassium carbonate) before electrolysis (for example, S501, S701), during electrolysis (for example, S503, S703), or after electrolysis (for example, S505, S705).

[0141] According to the above configuration, for example, adding a carbonate-based electrolyte before electrolysis quickly raises the conductivity of the electrolyzed water to the target range, ensuring stable start-up during current application to the electrolytic cell and improving the reproducibility of reaching the target pH during recovery of the aroma-enhanced electrolyzed water. Furthermore, for example, adding a carbonate-based electrolyte stepwise during electrolysis suppresses conductivity fluctuations and voltage fluctuations, thereby maintaining the stability of the electrolysis reaction and preventing excessive gas generation. Furthermore, for example, adding a trace amount of carbonate-based electrolyte after electrolysis imparts pH buffering ability, thereby reducing pH drift during storage and facilitating the maintenance of the aroma tone. Furthermore, for example, selecting a carbonate-based electrolyte and operating a separate dedicated chemical injection line reduces the contamination of available chlorine while facilitating quality index management, thereby improving the reproducibility of continuous operation.

[0142] (7) A method for producing aroma electrolyzed water (e.g., aroma electrolyzed water 103) includes the steps of distilling a plant material (e.g., raw material 101) (e.g., S403: distillation operation), cooling and condensing the vapor generated in the distillation step (e.g., S404: cooling and condensation), separating the distilled water obtained in the cooling and condensing step into oil and water (e.g., S405: oil and water separation) and recovering aroma oil (e.g., aroma oil 105) and aroma distilled water (e.g., aroma distilled water 102) (e.g., S406: recovery and temporary storage), supplying the aroma distilled water as water to be electrolyzed (e.g., raw water) to an electrolytic cell (e.g., electrolysis device 120, electrolysis unit 330) and electrolyzing it (e.g., S503: production in the electrolysis unit), and recovering alkaline aroma electrolyzed water from the electrolytic cell (e.g., S504: recovery, storage, and sidestream treatment).

[0143] According to the above configuration, for example, the continuous use of the distillation process and the cooling and condensation processes suppresses the contamination of high-boiling-point components and solids in the plant material, thereby adjusting the properties of the aroma distilled water to an aqueous phase suitable for electrolysis. Furthermore, for example, the use of an oil-water separation process removes hydrophobic components from the aqueous phase, reducing electrode contamination and foaming in the electrolytic cell and improving the stability of continuous operation. Furthermore, for example, the use of electrolyzed aroma distilled water as the water to be electrolyzed imparts alkalinity to the aqueous phase while making it easier to retain aromatic components, thereby improving the usability of the aroma electrolyzed water in terms of both functionality and fragrance. Furthermore, for example, the use of parallel recovery of aroma oil and aroma distilled water enables the effective use of by-products, thereby increasing resource utilization efficiency.

[0144] (8) Aroma electrolyzed water (e.g., aroma electrolyzed water 103) is obtained by electrolyzing (electrolysis device 120, electrolysis unit 330) aroma distilled water (e.g., aroma distilled water 102) obtained by distilling (e.g., distillation device 110) plant raw material (e.g., raw material 101) as water to be electrolyzed (e.g., raw water), and is alkaline and contains aromatic components derived from the plant raw material.

[0145] According to the above configuration, for example, aroma electrolyzed water obtained by electrolyzing aroma distilled water obtained by distilling plant materials as the electrolyzed water exhibits alkaline properties, and therefore, the aroma electrolyzed water can exhibit functions that contribute to the removal of dirt derived from oils and fats and the neutralization of acidic odors.Furthermore, for example, since the aroma electrolyzed water contains aromatic components derived from plant materials, the aroma electrolyzed water can enhance odor acceptance during use without relying on the addition of external fragrances.
