Description

Technical Field

[0001] This invention relates to the field of daily chemical technology, and more specifically, to a method for producing an artemisia annua shower gel. Background Technology

[0002] With the improvement of people's living standards and the popularization of healthy skincare concepts, daily chemical personal care products are accelerating their upgrade towards natural plant sources and precise functions. Consumers' demand for shower gels has shifted from basic cleansing to composite products that combine gentle care and effective skincare. Among them, personal care products with added active ingredients from traditional Chinese herbs are highly favored by the market due to their high safety and clear efficacy. Artemisia annua, as a traditional Chinese medicine unique to my country, has extracts rich in artemisinin, flavonoids, volatile oils, and polysaccharide active substances. Modern pharmacological studies have confirmed that it has multiple effects such as broad-spectrum antibacterial, anti-inflammatory and antipruritic, soothing of sensitive skin, and anti-oxidation. Its scientific compounding and application in shower gel products can effectively relieve discomfort symptoms such as itchy, dry, and red skin, and has extremely high application value and broad market prospects. Currently, the industrial production of artemisia-based shower gels generally adopts a standard process of "ingredient preparation - heating and stirring - cooling and settling - filling". The core processes are all completed in the reaction mixing tank. However, there is an insurmountable contradiction in the existing production process and supporting equipment: the core plant active ingredients such as artemisia extract, aloe vera extract, and tea polyphenols are all heat-sensitive substances. When exposed to an environment above 40°C for a long time, they will undergo varying degrees of oxidation and decomposition and loss of bioactivity, which directly leads to a decrease in the antibacterial, antipruritic, soothing and skin care effects of the product. Moreover, it is difficult to control the quality stability between batches. However, in order to ensure the full dissolution of surfactants, thickeners and other excipients and the uniformity and stability of the system, the production process must carry out heating and stirring operations, and a certain temperature and holding time are required. How to maximize the preservation of the bioactivity of plant active ingredients while ensuring production efficiency and product system stability, and at the same time control the equipment manufacturing cost and operating energy consumption, has become a key technical problem that urgently needs to be solved in the industrial production of artemisia-based functional shower gels. In the heating process, almost all existing reaction mixing tanks adopt a fixed welded jacket heating structure, that is, the jacket is permanently connected to the outer wall of the reaction tank by welding to form a closed heat exchange cavity. The heat exchange medium such as hot water or steam circulates in the cavity and heats the internal materials through heat conduction through the tank wall. Although this structure has mature technology and low manufacturing cost, it has an inherent defect that cannot be overcome: when the materials in the reaction mixing tank need to be cooled, even if the operator immediately cuts off the supply of heat exchange medium, the jacket will still be tightly wrapped around the outer wall of the reaction mixing tank. The large amount of sensible heat stored in the jacket itself and the residual heat exchange medium inside will continue to be transferred into the tank, resulting in extremely low cooling efficiency. For example, Chinese utility model patent application number 202020696526.9 discloses a combined heating reactor, and Chinese utility model patent application number 202320138157.5 discloses a reactor with uniform heating. Although the above-mentioned prior art has improved the heating uniformity and heat transfer efficiency to a certain extent through internal structure optimization, it has not overcome the core limitation of the fixed welded jacket structure - the jacket and the reactor wall are permanently fixed, and it is impossible to quickly switch between heating and insulation states according to process requirements. This results in a large amount of sensible heat being stored in the jacket itself and the heat exchange medium remaining inside after the heating and insulation process is completed. This residual heat will be continuously and slowly conducted to the material inside the tank through the tank wall, which greatly reduces the cooling rate of the material and significantly prolongs the high temperature exposure time of the material, thereby causing irreversible decomposition and loss of activity of heat-sensitive plant active ingredients such as artemisia annua and aloe vera.

[0014] Beneficial effects This invention provides a method for preparing artemisia annua shower gel, which has the following beneficial effects: The production method of this artemisia annua shower gel utilizes a rotating stirring rod and multiple rotating water wheels within a reaction mixing tank.

The heating jacket contains multiple heat exchange plates that can form a complete heat exchange cylinder, enabling rapid switching between heating and insulation states according to process requirements.

Furthermore, the arrangement of multiple fan blades on the side of the heat exchange plates near the reaction mixing tank, which rotate synchronously with the water wheels, generates directional forced convection during the cooling phase, significantly increasing the cooling rate and shortening the high-temperature residence time of the materials. This maximizes the preservation of the bioactivity of heat-sensitive plant active ingredients such as artemisia annua extract. Simultaneously, the fluid kinetic energy generated during stirring drives heat dissipation, achieving cascaded energy utilization and effectively reducing equipment manufacturing costs and operating energy consumption.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 While existing technologies have improved heating uniformity and heat transfer efficiency to some extent through internal structural optimization, they have not overcome the core limitation of the fixed welded jacket structure—the jacket and the reaction vessel wall are permanently fixed, making it impossible to quickly switch between heating and insulation states according to process requirements. This results in a large amount of sensible heat being stored in the jacket itself and the residual heat exchange medium inside after the heating and insulation process is completed. This residual heat is continuously and slowly conducted to the material inside the vessel through the vessel wall, which significantly reduces the cooling rate of the material and significantly prolongs the high-temperature exposure time of the material. Consequently, it causes irreversible decomposition and loss of activity of heat-sensitive plant active ingredients such as artemisia annua and aloe vera. This embodiment is invented to solve the above problems.

[0019] Please see Figures 1 to 6 This invention provides a technical solution: a method for preparing an artemisia annua shower gel, comprising the following steps: S1: Add plant extracts, plant oils, activated water and surfactants into reaction mixing tank 1, and stir and mix evenly at 40-50℃; S2: Add thickener and excipients to reaction mixing tank 1, heat to 65-70℃ and keep warm while stirring; S3: Cool the material in reaction mixing tank 1 to room temperature and let it stand to obtain the final product; The plant extract is a combination of tea polyphenols, lemon extract, aloe vera extract, and artemisia annua extract; The reaction mixing tank 1 is equipped with a rotatable stirring rod 9, and multiple rotatable water wheels 10 are provided on the inner circumference of the reaction mixing tank 1. The bottom of the outer circumference of the reaction mixing tank 1 is wrapped with a heating jacket 2, and multiple heat exchange plates 4 that can be enclosed to form a complete heat exchange cylinder are provided inside the heating jacket 2. Multiple fan blades 12 that can rotate synchronously with the water wheels 10 are provided on the side of the multiple heat exchange plates 4 near the reaction mixing tank 1. The space between the heating jacket 2 and the heat exchange plates 4 is filled with continuously flowing hot water.

[0020] Please see Figures 2 to 6 A drive motor is provided at the top of the reaction mixing tank 1, and the top of the stirring rod 9 extends to the outside of the reaction mixing tank 1 and is fixedly connected to the output shaft of the drive motor. Multiple sets of stirring blades are provided on the outer circumferential surface of the stirring rod 9. The stirring rod 9 is rotatably connected to the reaction mixing tank 1. When the drive motor is working, it drives the stirring rod 9 to rotate, which in turn drives multiple sets of stirring blades to rotate synchronously, thereby achieving the mixing of materials in the reaction mixing tank 1. The top and bottom of the inner circumferential surface of the heating jacket 2 are fixedly connected to the partition plate 3. The inner walls of the two partition plates 3 are fixedly connected to the outer circumferential surface of the reaction mixing tank 1. Multiple heat exchange plates 4 are arranged between the two partition plates 3. Multiple guide pull-back components are provided at the upper and lower ends of the side of the multiple heat exchange plates 4 away from the reaction mixing tank 1. The end of the guide pull-back component away from the heat exchange plate 4 is fixedly connected to the heating jacket 2. Therefore, through the separation effect of the two partition plates 3, the inner wall of the heating jacket 2, the heat exchange plate 4 and the partition plate 3 together form an independent heating space for accommodating the circulating heat exchange medium. The guide pull-back component includes a first telescopic barrel 7 fixedly connected to the inner circumferential surface of the heating sleeve 2, and a first telescopic rod 8 fixedly connected to the outer circumferential surface of the heat exchange plate 4. The end of the first telescopic rod 8 away from the heat exchange plate 4 is slidably connected inside the first telescopic barrel 7. A first tension spring 6 is sleeved on the first telescopic rod 8 and the first telescopic barrel 7. The two ends of the first tension spring 6 are fixedly connected to the heating sleeve 2 and the heat exchange plate 4, respectively. Although the first tension spring 6 is sleeved on the outer circumferential side of the first telescopic barrel 7 and the first telescopic rod 8, the first tension spring 6 never contacts the first telescopic barrel 7 and the first telescopic rod 8 during normal operation of the device. At the same time, through the sliding guide and axial limiting cooperation of the first telescopic barrel 7 and the first telescopic rod 8, the swaying and shaking of the heat exchange plate 4 during movement can be effectively avoided, greatly improving its stability and reliability during movement. A second elastic band 16 is fixedly connected to each other in the circumferential direction on the outer peripheral surfaces of multiple heat exchange plates 4, and a first elastic band 5 is fixedly connected to the top and bottom of the outer peripheral surfaces of multiple heat exchange plates 4, and the outer ring edge of the first elastic band 5 is fixedly connected to the partition plate 3. The second elastic band 16 is elongated, the first elastic band 5 is annular, and both the first elastic band 5 and the second elastic band 16 are made of rubber. The inner ring edges of the two first elastic bands 5 tightly wrap around the upper and lower ends of all heat exchange plates 4 (and the two are fixedly connected), while the outer ring edge of the first elastic band 5 is firmly fixed to the inner end face of the corresponding partition plate 3. This fully wrapped elastic sealing structure, together with multiple second elastic bands 16 fixedly connected between the circumferentially adjacent heat exchange plates 4, can completely seal the circumferential gap between adjacent heat exchange plates 4 and the axial gap between the upper and lower ends of the heat exchange plates 4 and the partition plate 3, forming a leak-free complete closed cavity. Meanwhile, since both the first elastic band 5 and the second elastic band 16 are made of highly elastic rubber, they have excellent tensile deformation capacity and resilience. When the heat exchange plate 4 moves radially, the elastic band can stretch or contract synchronously with the displacement of the heat exchange plate 4. This will not restrict the normal movement trajectory of the heat exchange plate 4, and can also fundamentally eliminate the risk of heat exchange medium leakage. Meanwhile, an inlet pipe is provided at the top of the outer circumference of the heating jacket 2, and an outlet pipe is provided at the bottom of the outer circumference of the heating jacket 2. Hot water at a preset temperature is continuously introduced into the heating enclosed space formed by multiple heat exchange plates 4, multiple second elastic bands 16, two first elastic bands 5, two partition plates 3, and the heating jacket 2 through the inlet pipe. When the water pressure in the enclosed space reaches the set value, the water pressure acting evenly on the outer circumference of all heat exchange plates 4 will overcome the preload of the first tension spring 6, pushing the heat exchange plates 4 along the first telescopic rod 8 and the first The guide structure formed by the telescopic barrel 7 moves smoothly inward until the inner circumferential surface of the heat exchange plate 4 is completely and tightly attached to the outer circumferential surface of the reaction mixing tank 1. At this time, a tight contact heat conduction interface without air gap is formed between the heat exchange plate 4 and the reaction mixing tank 1, which completely eliminates the adverse effect of air thermal resistance on heat transfer efficiency. The heat carried by the hot water in the heating closed space can be quickly conducted to the tank wall of the reaction mixing tank 1 through the metal substrate of the heat exchange plate 4, and then evenly transferred to the mixed material inside the tank wall, so as to achieve rapid and uniform heating of the material. Meanwhile, when the process requires cooling of the material in the reaction mixing tank 1, a quick switch can be achieved simply by adjusting the opening of the liquid inlet valve to reduce the water pressure in the heated enclosed space. When the water pressure in the enclosed space drops below the reset tension of the first tension spring 6, the first tension spring 6 will pull the heat exchange plate 4 to move smoothly outward, so that the inner circumferential surface of the heat exchange plate 4 is completely separated from the outer circumferential surface of the reaction mixing tank 1. At this time, a static air gap will be formed between the two. Since the thermal conductivity of air is much lower than that of metal and water, it is an excellent heat insulation medium that can effectively block the heat transfer from the hot water in the heated enclosed space to the reaction mixing tank 1, thereby causing the temperature of the material in the tank to drop rapidly. Precise cooling control can be achieved without the need for an additional independent cooling system.

[0021] Example 2 The above embodiments, through the innovative design of water pressure driving the radial clutch of the heat exchange plate 4, successfully achieve rapid switching between heating and insulation states. The material cooling process can be completed without the need for an additional independent cooling unit, significantly simplifying the equipment structure and reducing manufacturing costs and operating energy consumption. It has significant practical value in production scenarios. However, in actual industrial production applications, it was found that this cooling method still has significant limitations: it relies solely on natural convection and radiation heat exchange between the exposed tank wall of the reaction mixing tank 1 and the outside air for heat dissipation. Its heat exchange power is limited, and its heat exchange efficiency is greatly affected by external factors such as ambient temperature, workshop air velocity, and air humidity, especially in summer. In a warm production environment, natural cooling takes a significant amount of time, which not only severely slows down the production cycle of a single batch of products and restricts the capacity improvement of the entire production line, but more importantly, the core plant active ingredients such as artemisia annua extract, aloe vera extract, and tea polyphenols are quite sensitive to high temperatures. When exposed to environments above 40°C for a long time, they will undergo varying degrees of oxidation, decomposition, and loss of activity, resulting in damage to the antibacterial, antipruritic, and soothing skin care effects of the products. Ultimately, this affects the quality stability and batch consistency of the finished product. In order to further improve the cooling rate of materials, significantly shorten the cooling time, and maximize the preservation of the bioactivity of plant active ingredients, while taking into account the simplicity of the equipment structure and the economy of operation, this embodiment is invented.

[0022] Please see Figures 2 to 6 Based on the above embodiments, the technical solution adopted includes that the upper surface of the heating sleeve 2 is provided with a plurality of first air ports 21, the lower surface of the heating sleeve 2 is provided with a plurality of second air ports 22, and a plurality of third air ports 23 are uniformly provided on the side of the plurality of partition plates 3 near the heating sleeve 2. Therefore, when the first tension spring 6 pulls the multiple heat exchange plates 4 completely separated from the outer periphery of the reaction mixing tank 1, the vertically connected air passage structure will automatically open. Outside ambient temperature air can freely enter the internal cavity of the heating jacket 2 through the first air port 21 on the upper surface or the second air port 22 on the lower surface, and then diffuse evenly into the annular gap between the heat exchange plates 4 and the reaction mixing tank 1 through the multiple third air ports 23 evenly distributed on the upper and lower partition plates 3. Originally, this gap contained a static air layer, where heat transfer relied solely on extremely inefficient molecular conduction. The flowing air introduced through the vent will form a continuous natural convection circulation, which will quickly carry away the heat emitted from the tank wall of the reaction mixing tank 1 and discharge it to the external environment. This completely breaks the original static air heat insulation barrier, transforms the heat exchange mode from inefficient static heat conduction to efficient dynamic convection heat exchange, and can significantly improve the overall heat dissipation efficiency of the reaction mixing tank 1 without adding any additional power equipment. This greatly accelerates the cooling rate of the solution in the tank, effectively shortens the high-temperature residence time of the material, and maximizes the protection of the bioactivity of heat-sensitive active ingredients such as artemisia annua extract and aloe vera extract. A first rotating shaft 11 with one end penetrating through the reaction mixing tank 1 is fixedly connected to the middle of the water wheel 10, and the first rotating shaft 11 is rotatably connected to the reaction mixing tank 1. An auxiliary telescopic component is provided at the end of the first rotating shaft 11 away from the water wheel 10, and the fan blade 12 is fixedly connected to the auxiliary telescopic component. Therefore, when the drive motor drives the stirring rod 9 and stirring blades to rotate continuously, it can drive the material in the reaction mixing tank 1 to form a directional circulation flow. The continuous flow of the material will directly impact and drive the water wheel 10 to rotate synchronously around its own axis. During the rotation, the water wheel 10 will continuously disturb the surrounding material and generate multiple sets of auxiliary vortices in the tank, further breaking the laminar flow state of the material, enhancing the diffusion and convection effect between different components, and making the solution more uniform and sufficient. At the same time, the rotation of the water wheel 10 will synchronously drive the first rotating shaft 11 to rotate coaxially, providing stable power for the subsequent linkage operation of the fan blades 12. Multiple heat exchange plates 4 are evenly provided with multiple hidden grooves on one side near the reaction mixing tank 1, and multiple fan blades 12 can temporarily enter into the corresponding hidden grooves. The auxiliary telescopic component is fixedly connected to a first spring 14 at one end near the reaction mixing tank 1, and a limiting circular plate 13 is fixedly connected to the other end of the first spring 14 away from the auxiliary telescopic component. The limiting circular plate 13 can be rotatably embedded in the reaction mixing tank 1, and the limiting circular plate 13 is rotatably connected to the first rotating shaft 11. Therefore, when the water wheel 10 rotates, it can drive the first rotating shaft 11 to rotate synchronously. The auxiliary telescopic component includes a second telescopic cylinder 15 that is slidably and rotatably mounted on a first rotating shaft 11, a driven auxiliary plate 18 that is fixedly connected to the end of the first rotating shaft 11 away from the water wheel 10 and is rotatably and slidably mounted inside the second telescopic cylinder 15, a plurality of driven auxiliary rods 19 that are fixedly connected to the side of the driven auxiliary plate 18 near the limiting circular plate 13, a plurality of driven limiting grooves 20 that can be adapted to the plurality of driven auxiliary rods 19 that are opened on the inner wall of the second telescopic cylinder 15, a first spring 14 that is fixedly connected to the end away from the limiting circular plate 13 on the second telescopic cylinder 15, and a fan blade 12 that is fixedly connected to the second telescopic cylinder 15. Therefore, when the first rotating shaft 11 rotates, it can drive the driven auxiliary plate 18 to rotate synchronously, and the rotation of the driven auxiliary plate 18 can drive multiple driven auxiliary rods 19 to rotate synchronously. When the water pressure in the heated enclosed space presses against the heat exchange plate 4 and tightly adheres to the outer circumference of the reaction mixing tank 1, the inner side of the hidden groove on the heat exchange plate 4 will simultaneously press against the outer end face of the second telescopic cylinder 15, forcing the second telescopic cylinder 15 to overcome the elastic force of the first spring 14 and move towards the reaction mixing tank 1. At this time, although the rotation of the first rotating shaft 11 can be synchronously rotated by the driven auxiliary plate 18 with multiple driven auxiliary rods 19, the driven auxiliary rods 19 are not inserted into the driven limiting groove 20, and the two are in a completely disengaged free-spinning state. Therefore, the rotation of the first rotating shaft 11 will not be transmitted to the second telescopic cylinder 15, and the fan blade 12 remains stationary and will not interfere with the heating process. As the water pressure in the heated enclosed space gradually decreases, the restoring force of the first tension spring 6 pulls the heat exchange plate 4 to move smoothly away from the reaction mixing tank 1. At this time, the first spring 14 releases its pre-stored elastic potential energy, pushing the second telescopic cylinder 15 to move synchronously away from the reaction mixing tank 1. As the second telescopic cylinder 15 continues to extend, the driven auxiliary rod 19 will be inserted into the matching driven limiting groove 20. (Since the driven auxiliary rod 19 always maintains a uniform and continuous rotation with the first rotating shaft 11, while the second telescopic cylinder 15 is in a completely stationary non-transmission state at the initial stage of extension, the circumferential opening position of the driven limiting groove 20 is almost impossible to precisely correspond to the circumferential position of the driven auxiliary rod 19 when they initially make axial contact. At this time, under the stable axial thrust continuously applied by the first spring 14, the end face of the driven auxiliary rod 19 will contact the inner wall of the second telescopic cylinder 15.) A low-pressure sliding friction contact is formed on the surface, and the driven auxiliary rod 19 will smoothly slide in a circular motion on the end face of the second telescopic cylinder 15. As the driven auxiliary rod 19 continues to rotate, at the instant when its circumferential position is exactly aligned with the opening position of the driven limiting groove 20, the axial thrust of the first spring 14 will immediately push the driven auxiliary rod 19 to automatically slide into and tightly engage in the driven limiting groove 20, completing the automatic positioning and reliable engagement of power, realizing the automatic engagement and transmission of power. After the driven auxiliary rod 19 and the driven limiting groove 20 are engaged, the rotation of the first rotating shaft 11 will cause the second telescopic cylinder 15 to rotate synchronously through the cooperation of the driven auxiliary rod 19 and the driven limiting groove 20. The rotation of the second telescopic cylinder 15 will then cause the limiting circular plate 13 to rotate synchronously through the pull of the first spring 14. At the same time, the second telescopic cylinder 15 will cause the fan blade 12 fixed on its outer circumferential surface to rotate. The rotation of the fan blade 12 generates a forced convection field in the annular gap between the heat exchange plate 4 and the reaction mixing tank 1, transforming the originally disordered natural convection into directional forced convection. This significantly improves the heat transfer coefficient between the air and the tank wall of the reaction mixing tank 1. The airflow generated by the fan blade 12 can continuously scour the outer surface of the reaction mixing tank 1, promptly removing the heat dissipated from the tank wall. At the same time, it continuously introduces low-temperature air from the outside into the heat exchange area, forming a highly efficient circulating heat exchange system. Meanwhile, during the mixing and stirring of the solution in the reaction mixing tank 1, the stirring blades not only make the temperature of the solution in the reaction mixing tank 1 more uniform, avoiding local overheating, but also continuously drive the water wheel 10 to rotate through the directional flow of the solution, thereby providing a continuous source of power for the fan blade 12. Therefore, the design of using the fluid kinetic energy generated during the stirring process to drive the cooling fan achieves the cascade utilization of energy, without the need for any additional power equipment. While significantly improving the cooling rate, it can also effectively reduce the operating energy consumption of the equipment. After the material in the reaction mixing tank 1 cools down to room temperature, the finished artemisia shower gel can be discharged from the discharge pipe at the bottom of the reaction mixing tank 1. When the next batch of production is required, the water pressure in the heated enclosed space is increased again. The water pressure acting evenly on the outer circumference of the heat exchange plate 4 will overcome the pre-tightening force of the first tension spring 6 and push the heat exchange plate 4 towards the reaction mixing tank 1 until the inner circumference of the heat exchange plate 4 is tightly attached to the outer circumference of the reaction mixing tank 1 again. During this process, the inner side of the hidden groove on the heat exchange plate 4 will press against the outer end face of the second telescopic cylinder 15 again, forcing the second telescopic cylinder 15 to overcome the elastic force of the first spring 14 and move towards the reaction mixing tank 1. This causes the driven auxiliary rod 19 to separate from the driven limiting groove 20 again, the power transmission is automatically disconnected, the second telescopic cylinder 15 and the fan blade 12 will stop rotating, and the equipment will automatically switch back to the heating working mode to prepare for the next batch of production.

[0023] In summary, the method for producing this artemisia annua shower gel utilizes a scientifically formulated blend of tea polyphenols, lemon extract, aloe vera extract, and artemisia annua extract, combined with the specialized structural design of the reaction mixing tank 1. This achieves highly efficient synergy between heating and cooling processes during the production of daily chemical personal care products. On one hand, water pressure drives the heat exchange plate 4 to radially engage and disengage along the guide structure of the first telescopic barrel 7 and the first telescopic rod 8. Combined with the fully sealed design of the first elastic band 5 and the second elastic band 16, this creates a tight, air-free thermal interface during the heating phase, enabling rapid and uniform heating of the materials. On the other hand, it automatically forms an air insulation layer during the cooling phase, blocking heat transfer from the hot water inside the heating jacket 2, eliminating the need for an additional independent cooling unit. The unit can complete basic cooling. On the other hand, it innovatively uses the fluid kinetic energy generated during the stirring process of the stirring rod 9 to drive the water wheel 10 to rotate. Then, through the automatic positioning clutch transmission mechanism composed of the second telescopic cylinder 15, the driven auxiliary plate 18, the driven auxiliary rod 19, the driven limiting groove 20 and the first spring 14, the fan blade 12 is automatically started during the cooling stage and generates forced convection. With the through air path formed by the first air port 21 and the second air port 22 on the heating jacket 2 and the third air port 23 on the partition plate 3, the natural convection heat exchange is upgraded to forced convection heat exchange, which effectively improves production efficiency and product batch stability, and significantly reduces equipment manufacturing costs and operating energy consumption. It has good industrial promotion and application value.
