Description

Technical Field

[0001] This invention relates to the field of spray mask technology, and in particular to an apparatus for preparing a zinc-containing small molecule cluster polysaccharide solution. Background Technology

[0002] Application number CN201911137042.9 discloses a spray mask based on small molecule cluster water and its preparation method. This invention utilizes 14.05-86.62% small molecule cluster water as a solvent, which is the main material of the spray mask. The small molecule cluster water is composed of 5-8 water molecules and possesses strong penetrating power, strong dissolving power, strong diffusivity, strong volatility, strong transport capacity, and strong emulsifying power; it is also weakly alkaline. The small molecule cluster water has a high oxygen content (dissolved oxygen greater than 6 mg / L), which can bring more oxygen and nutrients to the body's tissue cells; at the same time, it removes metabolic waste and toxins from cells, offering numerous benefits. Because small water molecule clusters possess energy and exhibit strong diffusion properties, in the context of facial mask spraying, the spray distance from the nozzle of the spray device (such as a small spray bottle) to the skin surface (such as the face) is approximately 3-6 cm. The small water molecule clusters, along with their accompanying active ingredients, penetrate and are carried into the skin, thus demonstrating their advantages in facial mask application. However, because the misted water is exposed to the air during the spraying process, its high volatility accelerates the natural evaporation of water vapor, resulting in the loss of some small water molecule clusters. This affects the effectiveness and efficiency of small water molecule cluster sprayed facial masks. This phenomenon is particularly noticeable in dry or hot weather, representing a deficiency in existing technology.

[0003] Application number CN202111122678.3 discloses a Tremella fuciformis polysaccharide topical facial mask and its preparation method. In this invention, besides using Tremella fuciformis polysaccharide, deionized water constitutes the largest proportion and is the main material used. CN113069396A discloses a moisturizing facial mask and its preparation method, which also uses 70-85% deionized water. According to research, deionized water undergoes special treatment, removing only impurities and harmful substances while retaining the purest state of water molecules (and eliminating beneficial substances), without increasing the energy of the water. This comparison indicates that such technologies also have shortcomings; their formulations are not entirely reasonable, thus weakening the contribution of the excellent properties of Tremella fuciformis polysaccharide to the facial mask product.

[0004] On the other hand, zinc is a beneficial trace element for the human body. Zinc promotes skin wound repair, regulates immune cells, and enhances skin immunity. It has long been used as a therapeutic adjuvant in skin care and is easily delivered by small-molecule cluster water to maximize its effects. So-called healthy water refers to water that meets the latest national group standard "Standards for Healthy Drinking Water Quality" (TCAPS-2021) issued in 2021. The most significant feature of the "Standards for Healthy Drinking Water Quality" is its affirmation of beneficial trace elements such as zinc and their recommended content ranges, such as zinc: the limit is 0.05-1.0 mg / L, and the target value is 0.2-1.0 mg / L. However, there are no publicly available reports on using healthy water to prepare spray-on masks. Therefore, it is necessary to apply a zinc-rich small-molecule cluster water to skin care.

[0005] Tremella fuciformis, a traditional food and medicinal ingredient, has become widely available and enjoyed by everyone thanks to successful artificial cultivation techniques. Tremella fuciformis polysaccharides are its active ingredient, rich in natural plant-based colloids, making them viscous and smooth. When used in skincare cosmetics, tremella fuciformis polysaccharides can help repair the epidermis, increase its moisture content, and possess excellent moisturizing and water-locking abilities. It can absorb a large amount of water, maintaining high moisturizing properties under both low and high humidity conditions. It increases the moisture content of the stratum corneum, giving the skin a soft feel; it prevents moisture evaporation from the skin surface, thus preventing skin aging, promoting the growth of elastic cells, and has anti-aging and antioxidant effects. Therefore, it is often used in high-end cosmetics.

[0006] Because Tremella polysaccharide has a high moisturizing and water-retaining capacity, it needs to work closely with water in skincare applications, especially with small molecule cluster water. Functionally, they support each other. Small molecule cluster water needs the protection of Tremella polysaccharide to prevent useless natural evaporation during use; while beneficial elements such as Tremella polysaccharide are easily carried into the skin and absorbed by the small molecule cluster water. This can make up for the shortcomings of existing mask liquid technology. Therefore, there is a need to provide a mask liquid that reduces evaporation, provides timely and long-lasting hydration, and is multi-purpose to meet market demand. Summary of the Invention

[0007] In view of this, the purpose of the present invention is to provide an apparatus and method for preparing zinc-containing small molecular cluster polysaccharide solution and its application, which has the advantages of continuous production, high production efficiency, good economy, large processing capacity and good stability.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below through specific embodiments and related drawings. Attached Figure Description

Detailed Implementation

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] like Figures 1-2 As shown, an apparatus for preparing a zinc-containing small molecule cluster polysaccharide solution includes a water purifier 1, a stirring pot 2, a reaction tank 3, a coarse filter tank 4, and a fine filter tank 5 connected in sequence. The water inlet of the water purifier is connected to a raw water inlet pipe. The stirring pot 2 is equipped with a stirring paddle 22, and the stirring paddle 22 has a jacket filled with far-infrared material. The reaction tank 3 includes a U-shaped tank 36 and a tank cover plate 33. A terahertz wave generator 31 is installed on the tank cover plate 33. At least two terahertz generators are provided. The U-shaped tank 36 is equipped with a spiral blade 35, and the U-shaped tank 36 has a jacket filled with far-infrared material. A motor is installed on the outer side of one end of the U-shaped tank 36. The main shaft of the motor is coaxially connected to one end of the spiral blade. The far-infrared material in the jacket can be tourmaline, or it can be tourmaline as the main component with the addition of other far-infrared materials.

[0022] The impeller blades are filled with far-infrared material so that they can radiate stronger far-infrared rays while being stirred in a hot environment. While stirring and impacting, far-infrared rays are radiated. With the help of an electric heating field (45~55°C), healthy water and tremella resonate. After 2 to 3 hours of operation, a slurry of 65~85 Hz small molecular cluster water and tremella polysaccharide dissolution solution can be formed.

[0023] The terahertz generator 31 generates terahertz waves that radiate to the water and generate heat, thus activating the water. The interlayer filled with far-infrared material in the U-shaped trough 36 not only provides some heat insulation and heat preservation, but more importantly, the terahertz waves radiated by the terahertz generator 31, along with the accompanying 50-60°C thermal field, cause the far-infrared material 34 in the interlayer of the trough 36 to radiate stronger and more far-infrared rays, forming a comprehensive effect of mutual support among the three energy fields.

[0024] Cleaned tremella fragments and healthy water are introduced into a mixing pot, heated, and slurried. Simultaneously, the water and tremella are subjected to far-infrared radiation from the jacket of the mixing paddle, resonating at the same frequency. After the slurry enters the reaction tank, it is pushed forward by the spiral blades and receives multiple radiations from terahertz waves, thermal fields, and far-infrared waves from the tank wall. These radiations work together to heat and resonate the slurry, promoting the separation of polysaccharides and the deep dissolution of smaller water and polysaccharide molecule clusters. Afterward, coarse filtration and fine filtration are performed. The fine filtrate is a zinc-containing small molecule cluster polysaccharide solution, which is the main material of the facial mask spray product.

[0025] This preparation device, through the application of multiple energy fields including the interaction of far-infrared fields and terahertz waves, has the advantages of continuous operation, high generation efficiency, good economy, large processing capacity, and good stability.

[0026] In this embodiment, the water purifier 1 is based on a conventional water purifier, with sintered particles containing zinc and other minerals added to the filter element. After filtration and slow release, it meets the requirements of the "Standards for Healthy Drinking Water Quality," and the zinc content in the filtered healthy water is required to be 0.05~10.0 mg / L. Alternatively, other water purifiers capable of producing healthy water with zinc, such as those with KDF filter elements, can also be used.

[0027] In this embodiment, the coarse filter tank 4 is provided with a coarse filter 41, the fine filter tank 5 is provided with a fine filter 51, and both the coarse filter tank 4 and the fine filter tank 5 are provided with a slag discharge port at the bottom. The coarse filter tank 4 and the fine filter tank 5 are respectively provided with a coarse filter slag trough 42 and a fine filter slag trough 52 below their respective slag discharge ports.

[0028] In this embodiment, an intermediate circulating water tank 7 is also included. A circulation pipe is connected between the coarse filter residue tank 42 and the fine filter residue tank 52 and the intermediate circulating water tank 7. A circulation pump 6 is connected to the circulation pipe. A return pipe is connected between the intermediate circulating water tank 7 and the mixing pot 2.

[0029] In this embodiment, the coarse filter 41 is connected to an intermediate pipe leading to the fine filter tank 5, and an intermediate pump 43 is connected to the intermediate pipe. The fine filter 51 is connected to a fine filtrate outlet pipe.

[0030] The coarse filter 41 in the coarse filter tank is composed of multiple porous filter screens wrapped with non-woven fabric. The liquid inlet end of the middle tube extends into the middle of the filter screen. After filtration, the relatively clean liquid enters the fine filter tank for further filtration. A small amount of coarse filtrate and filter residue retained on the non-woven fabric surface flows into the coarse filter residue tank 42 and is then pumped by the circulation pump 6 to the middle circulating water tank for recycling.

[0031] After being filtered by the fine filter 51 in the fine filter tank 5, the liquid is extracted by the fine filtrate outlet pipe and stored in a centralized manner. It can then be used as the main material for the facial mask spray liquid. The remaining small amount of fine filtrate is collected into the fine filtrate tank 52 and then pumped by the circulation pump 6 to the intermediate circulating water tank for recycling. The fine filter 51 itself is existing technology and can be purchased directly on the market. Its structure and principle will not be described in detail here.

[0032] In this embodiment, a mixing pot 2 is provided with a mixing pot cover 21 on top of the mixing pot 2. The mixing pot cover 21 is provided with a water inlet 211, a circulating water inlet 212 and a feeding port 213. The water inlet 211 is connected to the water purifier 1, and the circulating water inlet 212 is connected to the return pipe. An electric heater 23 is provided at the bottom of the mixing pot 2. A stirring motor 24 for driving the stirring paddle 22 is installed on the mixing pot cover 21. The main shaft of the stirring motor 24 is coaxially connected to the upper end of the stirring paddle 22 through a coupling. A first discharge pipe 25 with a gate is provided at the bottom of the mixing pot 2.

[0033] In this embodiment, one end of the reaction tank 3 is provided with an inlet that connects to the first discharge pipe 25, and the other end of the reaction tank 3 is provided with a second discharge pipe 37 with a gate, which is connected to the coarse filter tank 4; the tank cover plate 33 is provided with an exhaust pipe 32; the exhaust pipe 32 is activated to help discharge the excess hot air generated by the cooling fan of the terahertz wave generator, so as to ensure that the terahertz wave generator can work stably for a long time.

[0034] Under the combined intervention and interaction of multiple energy fields, including stirring and impact, rotational propulsion (mechanical force), thermal field, far-infrared field (wave), and terahertz wave, a large amount of additional energy is input, causing the hydrogen bonds between water molecules to break, producing stable small molecule cluster water as a solvent to form the main material of a zinc-rich small molecule cluster polysaccharide spraying liquid. Simultaneously, the combined intervention of multiple energy fields promotes the production of more short-chain polysaccharides from *Tremella fuciformis*, making it easier to achieve deep dissolution. The method for producing small molecule cluster water and small molecule cluster polysaccharide liquid in this invention is simple, allows for continuous production, has low energy consumption, and is economical. The small molecule cluster water produced by this invention has good stability, has been sterilized by far-infrared radiation, and can maintain the characteristics of small molecule water and *Tremella fuciformis* polysaccharides for a long time. It is suitable for applications requiring long-term maintenance of the inherent characteristics of small molecule cluster water, working conditions, and usage scenarios, such as cosmetics and facial mask liquids.

[0035] A method for preparing a zinc-containing small-molecule cluster polysaccharide solution, using the apparatus for preparing a zinc-containing small-molecule cluster polysaccharide solution as described above, includes the following steps: (1) Pass the raw water into the water purifier 1, introduce the healthy water containing zinc element produced by filtration and purification into the mixing pot 2, pour the clean tremella fragments into the mixing pot 2, turn on the electric heater at the bottom of the mixing pot 2 and start the stirring paddle 22 to slurry, control the temperature at 45~55°C, and the working time is 2~3 hours; under the stirring impact of the stirring paddle, the far-infrared material in the jacket of the stirring paddle is radiated with strong far-infrared rays to sterilize the water and resonate with the water and the tremella. The resonance causes the cell wall of the tremella to rupture and the long chain of polysaccharide to break, which promotes the separation of polysaccharides; at the same time, the small molecule cluster water as a solvent has super permeability, solubility, emulsification and transport properties, which promotes the dissolution of tremella polysaccharides and enters the small molecule cluster water, forming a mixed slurry of small molecule cluster water and polysaccharide liquid, producing 65~85 Hz small molecule cluster water, which at the same time promotes the dissolution of tremella fragments into tremella polysaccharides into slurry; (2) Open the first discharge pipe 25 of the mixing tank 2, and open the second discharge pipe 37 of the reaction tank 3 after an appropriate delay; the slurry enters the reaction tank 3, and while being pushed forward by the spiral blades, the slurry is irradiated by the terahertz wave of the terahertz generator and heated by the accompanying thermal field (50~60℃). In addition, the far-infrared material in the U-shaped groove 36 jacket radiates more intense far-infrared rays under the help of the thermal field inside the reaction tank, which resonate with the water and tremella at the same frequency, promoting the production of stable small molecule cluster water at 40~70 Hz. Deep dissolution of Tremella polysaccharides; resonance causes Tremella cell wall rupture, further shearing the long chain structure of polysaccharides and promoting polysaccharide separation; the small molecular clusters of water, as a solvent, have super permeability and solubility, which further promote the deep dissolution of Tremella polysaccharides, forming a uniformly mixed, smaller, more stable, sterile, zinc-rich small molecular cluster polysaccharide solution; the process also deeply sterilizes the water; the speed at which the slurry is pushed by the spiral blades at 35° is controlled to ensure that the residence time in the reaction tank is maintained at 15-25 minutes; (3) The slurry is then filtered twice, through coarse filter 4 and fine filter 5, to obtain fine filtrate, which is zinc-containing small molecular cluster polysaccharide solution.

[0036] In this embodiment, in step (3), the concentrated slurry from the coarse filter tank 4 and the fine filter tank 5 is returned to the intermediate circulating water tank 7 by the circulating pump 6, and can be added to the mixing pot 2 for further processing and utilization as appropriate; in step (1), depending on the specific conditions of the processing site, the circulating water from the intermediate circulating water tank is added (or not added) from the circulating water inlet 212 of the mixing pot cover 21 into the mixing pot 2.

[0037] An application of a zinc-containing small molecule cluster polysaccharide solution involves preparing the zinc-containing small molecule cluster polysaccharide solution using the method described above, adding jasmine oil (0.5-1.5%) to the solution to formulate a facial mask spray, which can then be packaged in barrels or bottles for user use.
