Description

Technical Field

[0001] This invention relates to the field of cosmetic preparation technology, specifically to an ultra-high pressure homogenization and synergistic microencapsulation device for encapsulating whitening raw materials. Background Technology

[0002] In the field of skin-whitening cosmetic formulations, microencapsulation technology is a key method for protecting highly active and easily degradable skin-whitening ingredients such as Vitamin C and niacinamide. The first step of this technology is to thoroughly premix the core material (skin-whitening raw material) and the wall material (coating material) to form a homogeneous emulsion or suspension. The quality of premixing directly determines the effectiveness of subsequent ultra-high pressure homogenization and ultimately affects the encapsulation efficiency, particle size distribution, and stability of the microcapsules. If premixing is insufficient, agglomerated or stratified materials entering the ultra-high pressure homogenizer will not only reduce homogenization efficiency but may also cause blockage of the homogenization valve, or even prevent the formation of qualified nanoscale emulsion templates.

[0003] Currently, industrial production generally uses a split production line to complete this process, which typically includes premixing equipment, conveying equipment, and ultra-high pressure homogenizing equipment. First, the whitening raw materials are premixed using a premixing equipment, such as a high-speed shear disperser (FLUKO FA25 high-shear dispersion emulsifier). The high-speed rotation of the rotor-stator structure performs preliminary shearing and mixing of the materials. Then, the premixed slurry is stored in a transfer tank and conveyed to an ultra-high pressure homogenizer (such as GEA Niro Soavi NS3006H) through a conveying pipeline. The huge shear force and cavitation effect generated by the high-pressure pump and the interactive cavity further nano-scale the premixed liquid.

[0004] Existing production methods require the transfer and pumping of skin whitening raw materials between different devices, which is not only time-consuming and energy-intensive, but also increases the contact time between the active ingredients in the skin whitening raw materials and oxygen and light, thus increasing the risk of oxidation and failure of the skin whitening raw materials. Therefore, it is necessary to propose a skin whitening raw material encapsulation device that can simultaneously premix, transport, and homogenize skin whitening raw materials under ultra-high pressure, thereby improving the quality of skin whitening raw materials. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides an ultra-high pressure homogenization and synergistic microencapsulation device for whitening raw materials. Through the design of a premixing chamber, the device can premix the whitening raw materials, maintaining their fluidity and uniformity, and improving the processing effect of subsequent homogenization. While premixing the whitening raw materials, the device also automates their transport, eliminating the need for additional premixing and transport equipment. This integrated design improves the efficiency and quality of whitening product production.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A skin whitening raw material encapsulation device for ultra-high pressure homogenization and synergistic microencapsulation includes an ultra-high pressure homogenizer, a base, and a premixing chamber. The ultra-high pressure homogenizer is fixedly connected to the top of the base. A hollow support shaft is connected to the top of the ultra-high pressure homogenizer, the top of which penetrates the bottom of the premixing chamber and slides vertically therewith. Several discharge holes are opened on the upper part of the support shaft. A feed inlet is opened on the side wall of the premixing chamber, and a feeding cover is hinged to the feed inlet. A piston plate is fixedly connected to the top of the support shaft, and the piston plate slides vertically with the inner side wall of the premixing chamber. The base is provided with a first drive assembly for driving the premixing chamber to rotate and a second drive assembly for driving the premixing chamber to vibrate vertically.

[0007] The technical principles of the above solution are as follows:

[0008] Open the feeding cover and convey the whitening raw material through the feed inlet box to the bottom of the premix box; the first drive component and the second drive component make the premix box slide vertically back and forth while rotating, driving the whitening raw material to rotate and maintain the flowability of the whitening raw material; at the same time, the whitening raw material is oscillated to maintain the uniformity of the whitening raw material; during the process of the premix box sliding vertically back and forth along the support tube, the piston plate will generate relative movement with the premix box, thereby conveying the whitening raw material at the bottom of the premix box through the discharge port and the support tube to the ultra-high pressure homogenizer, thereby homogenizing the whitening raw material.

[0009] The above approach has the following beneficial effects:

[0010] 1. In existing technologies, the use of separate equipment for premixing and homogenizing whitening raw materials involves multiple steps, requiring the transfer and pumping of these materials between different devices. This is not only time-consuming and energy-intensive but also increases the contact time between the active ingredients and oxygen and light, raising the risk of oxidation and deterioration. This invention utilizes a premixing tank to premix the whitening raw materials, maintaining their flowability and uniformity, and improving the effectiveness of subsequent homogenization. Simultaneously, the whitening raw materials are automatically transported. This integrated design effectively reduces the risk of oxidation and deterioration, shortens preparation time, and improves the efficiency and quality of whitening product production.

[0011] 2. In the existing technology, the production cost of whitening products is extremely high due to the need for multiple equipment such as premixing equipment, transportation equipment and ultra-high pressure homogenizing equipment. The present invention, through the design of the premixing box, can realize the premixing, transportation and homogenization of whitening raw materials in an integrated manner, without the need to add additional premixing equipment and conveying equipment, effectively reducing the production cost of whitening products.

[0012] 3. This invention utilizes a premixing chamber design. The rotation of the premixing chamber ensures the fluidity of the whitening raw materials, preventing them from solidifying and affecting the subsequent homogenization process. Simultaneously, the vibration of the premixing chamber causes the whitening raw materials to vibrate, effectively improving their uniformity and fluidity, further enhancing the homogenization effect. Through the relative movement of the piston plate and the premixing chamber, the whitening raw materials are immediately transported to the ultra-high pressure homogenizer after premixing, ensuring timely delivery and preventing solidification or stratification due to prolonged transport time, which would otherwise affect the homogenization process.

[0013] Furthermore, a back plate is fixedly connected to the top of the base. The first drive assembly includes a controller and a first drive member fixedly connected to the side wall of the back plate. A main gear is coaxially fixedly connected to the output shaft of the first drive member, and a secondary gear is rotatably sleeved on the support shaft. The main gear meshes with the secondary gear. Several support tubes are fixedly connected to the top of the secondary gear. All support tubes penetrate the bottom of the premix box and slide vertically with it. The controller is used to drive the first drive member to run, thereby driving the main gear to rotate.

[0014] Beneficial effects: Through the design of the support tube, the premix box can rotate with the support tube, thereby driving the whitening raw materials to rotate, ensuring the fluidity of the whitening raw materials, and realizing the premixing of the whitening raw materials.

[0015] Furthermore, the second drive assembly includes a second drive member fixedly connected to the side wall of the back plate, a limit plate fixedly connected to the output shaft of the second drive member, a top rod fixedly connected to the top of the premix box, and the top rod located below the limit plate; a spring is sleeved on the support shaft, one end of the spring is fixedly connected to the top of the auxiliary gear, and the other end of the spring is fixedly connected to the bottom of the premix box.

[0016] Beneficial effects: Through the design of springs, top rods and limiting plates, the premixing box can vibrate vertically under the action of springs and limiting plates, thereby vibrating the whitening raw materials and achieving premixing of the whitening raw materials.

[0017] Furthermore, a reaction chamber is fixedly connected to the top of the base, and the side wall of the reaction chamber is connected to the side wall of the ultra-high pressure homogenizer; a stirring shaft is fixedly connected to the bottom of the main gear, the stirring shaft passes through the top wall of the reaction chamber and rotates with it, and several stirring rods are fixedly connected to the stirring shaft; a material outlet is opened at the bottom of the reaction chamber, and a material outlet cover is hinged at the material outlet; an addition port for adding crosslinking agent is opened on the side wall of the reaction chamber, and a sealing cover is hinged at the addition port.

[0018] Beneficial effects: This solution utilizes the rotation of the main gear to drive the stirring shaft, which can effectively stir the homogenized whitening raw materials and crosslinking agents, allowing the whitening raw materials to undergo a more uniform microencapsulation reaction, improving the production quality of whitening products. At the same time, it eliminates the need to design additional stirring equipment, reducing production costs.

[0019] Furthermore, a gas storage tank for storing inert gas is fixedly connected to one side of the base; the upper side wall of the premixing box is connected to the top of the gas storage tank, and a first one-way valve for supplying gas to the upper part of the premixing box is connected at the connection point; a condenser pipe is connected to the upper side wall of the premixing box, and a second one-way valve for supplying exhaust gas to the upper part of the premixing box is connected at the connection point; the end of the condenser pipe away from the premixing box is connected to the reaction chamber.

[0020] Beneficial effects: This solution utilizes the relative movement between the piston plate and the premixing chamber to automatically draw inert gas from the storage tank at the top of the premixing chamber. This gas is then transported to the reaction chamber through a condenser pipe to cool the homogenized whitening raw materials, ensuring the effectiveness of the active ingredients in the whitening raw materials and improving the quality of whitening products.

[0021] Furthermore, the upper part of each support pipe has several exhaust holes, all of which are located inside the premixing tank; the lower part of each support pipe has an air inlet, which is connected to the air storage tank, and the connection point between the two is connected to a third one-way valve for supplying air to the lower part of the premixing tank.

[0022] Beneficial effects: This solution utilizes the relative movement between the piston plate and the premixing tank to automatically draw inert gas from the storage tank at the bottom of the premixing tank. The gas is then transported to the bottom of the premixing tank through the exhaust port on the support pipe. The inert gas generates an impact airflow, which impacts the whitening raw materials, improving their flowability and uniformity, thereby enhancing the quality of the whitening product.

[0023] Furthermore, the condenser tube is spiral-shaped.

[0024] Beneficial effects: The spiral condenser tube can increase its own volume and surface area, improve its own capacity and condensation range, thereby improving the condensation time and condensation effect of inert gases, and improving the cooling effect of inert gases on whitening raw materials.

[0025] Furthermore, several elastic rods are fixedly connected to the bottom of the piston plate.

[0026] Beneficial effects: During the relative movement between the premixing tank and the piston plate, the elastic rod will also move relative to the whitening raw materials, thereby stirring and mixing the whitening raw materials and improving their fluidity and uniformity.

[0027] Furthermore, a ball bearing is rotatably connected to the top of the push rod.

[0028] Beneficial effects: The ball bearings can reduce the friction between the push rod and the limiting plate, improve the smoothness of the push rod moving along the bottom of the limiting plate, improve the premixing effect of the premixing box on the whitening raw materials, and at the same time reduce the wear and tear on the push rod and the limiting plate, thus increasing the service life of the device.

[0029] Furthermore, sealing sleeves are fixedly connected to the sliding fit points of the premix box, support shaft, and support tube.

[0030] Beneficial effects: The sealing sleeve can improve the airtightness of the premix box and prevent the whitening raw materials from leaking.

[0031] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0037] The following detailed description illustrates the specific implementation method:

[0038] Implementation, for example Figure 1 and Figure 2 As shown, the ultra-high pressure homogenization and microencapsulation equipment for skin whitening raw materials includes an ultra-high pressure homogenizer 1, a base 2, and a premixing chamber 3. The ultra-high pressure homogenizer 1 is bolted to the top of the base 2.

[0039] The top of the ultra-high pressure homogenizer 1 is connected to a hollow support shaft 4. The top of the support shaft 4 passes through the bottom of the premix box 3 and slides vertically with it. Several discharge holes 5 are opened on the upper part of the support shaft 4.

[0040] The premix box 3 has a feed inlet on its side wall, and a feed cover 6 is hinged to the feed inlet; a piston plate 7 is welded to the top of the support shaft 4, and several elastic rods 28 are fixedly bonded to the bottom of the piston plate 7; the piston plate 7 slides vertically with the inner side wall of the premix box 3.

[0041] The base 2 is provided with a first drive assembly for driving the premix box 3 to rotate and a second drive assembly for driving the premix box 3 to vibrate vertically.

[0042] like Figure 2 As shown, a back plate 8 is welded to the top of the base 2. The first drive assembly includes a controller and a first drive component 9 (a servo motor with a rated speed of 3000 rpm) bolted to the side wall of the back plate 8. A main gear 10 is coaxially bolted to the output shaft of the first drive component 9, and a secondary gear 11 is rotatably sleeved on the support shaft 4. The main gear 10 meshes with the secondary gear 11. Several support tubes 12 are bolted to the top of the secondary gear 11. The support tubes 12 all penetrate the bottom of the premix box 3 and slide vertically with it. The controller is used to drive the first drive component 9 to run, thereby driving the main gear 10 to rotate. Sealing sleeves 30 are fixedly bonded to the sliding contact points between the premix box 3 and the support shaft 4 and the support tubes 12.

[0043] like Figure 2 As shown, the second drive assembly includes a second drive component 13 (a servo motor with a rated speed of 1500 rpm) bolted to the side wall of the back plate 8. A limit plate 14 (adjustable range of 360°) is bolted to the output shaft of the second drive component 13. A top rod 15 is welded to the top of the premix box 3. A ball bearing 29 is rotatably connected to the top of the top rod 15. The top rod 15 is located below the limit plate 14. A spring 16 is sleeved on the support shaft 4. One end of the spring 16 is fixedly connected to the top of the auxiliary gear 11 with a screw, and the other end of the spring 16 is fixedly connected to the bottom of the premix box 3 with a screw.

[0044] Specifically, in the initial state, the limiting plate 14 is in a horizontal position. Before preparing the whitening product, the operator can adjust the rotation angle of the limiting plate 14 according to the actual needs (the required dispersion of the whitening raw materials). The larger the rotation angle of the limiting plate 14 (compared to the horizontal plane), the greater the vertical reciprocating sliding stroke of the premix box 3 (the maximum stroke is 25cm), and the greater the vibration amplitude of the whitening raw materials. This design effectively improves the versatility of the device, making it suitable for processing different types of whitening raw materials.

[0045] like Figure 2As shown, the operator starts the second drive unit 13 through the controller. The output shaft of the second drive unit 13 drives the limit plate 14 to rotate counterclockwise by 30°. Under the action of the spring 16, the ball bearing 29 always fits against the bottom of the limit plate 14. At this time, the operator opens the feeding cover 6 and adds whitening raw materials (including wall material and core material; in this embodiment, sodium alginate is used as the wall material and vitamin C as the core material) to the lower part of the premixing box 3. After adding, the operator closes the feeding cover 6 and starts the first drive unit 9 through the controller. The first drive unit 9 drives the main gear 10 to rotate, the main gear 10 drives the secondary gear 11 to rotate, and the secondary gear 11 drives the support tube 12 and the premixing box 3 to rotate around the support shaft 4 (at a speed of 150 rpm). The premixing box 3 drives the top rod 15 and the ball bearing 29 to rotate synchronously. During this process, the ball bearing... The ball bearing 29 rotates along the bottom of the limiting plate 14. Due to the limiting effect of the limiting plate 14, the limiting plate 14 will squeeze the ball bearing 29 and the push rod 15. When the ball bearing 29 rotates to the left side of the limiting plate 14, the push rod 15 and the premix box 3 will slide downwards, at which time the spring 16 is compressed. When the ball bearing 29 rotates to the right side of the limiting plate 14, the limiting effect of the limiting plate 14 disappears, the spring 16 returns to its original position, and pushes the premix box 3 and the push rod 15 to slide upwards. This process repeats, so that the premix box 3 can maintain vertical vibration during rotation (vibration frequency is about 8Hz, vibration amplitude is 10cm), thereby driving the whitening raw materials in the premix box 3 to rotate and vibrate continuously, improving the uniformity and fluidity of the whitening raw materials (the dispersion of sodium alginate and vitamin C is increased by about 30%), which is convenient for subsequent homogenization processing.

[0046] During this process, when the premix box 3 drives the whitening raw material to rotate, the elastic rod 28 on the piston plate 7 will generate relative movement with the whitening raw material, thereby stirring the whitening raw material (stirring speed is about 150 rpm) and improving the fluidity and uniformity of the whitening raw material; the whitening raw material will be conveyed to the ultra-high pressure homogenizer 1 through the discharge hole 5 and the support shaft 4 (conveyor speed is about 0.5L / min).

[0047] Whenever the premix box 3 slides upward, the space between the piston plate 7 and the lower part of the premix box 3 will be compressed. At this time, the whitening raw material will be transported more efficiently to the ultra-high pressure homogenizer 1 through the discharge hole 5 and the support shaft 4 (the conveying rate is increased to about 1.5L / min), thereby completing the conveying and homogenization of the whitening raw material.

[0048] like Figure 3 and Figure 4As shown, the top of the base 2 is bolted to a reaction chamber 17, and the side wall of the reaction chamber 17 is connected to the side wall of the ultra-high pressure homogenizer 1; the bottom of the main gear 10 is bolted to a stirring shaft 18, which passes through the top wall of the reaction chamber 17 and rotates with it; several stirring rods 19 are welded on the stirring shaft 18; a material outlet is opened at the bottom of the reaction chamber 17, and a material outlet cover 20 is hinged at the material outlet; an addition port for adding crosslinking agent is opened on the side wall of the reaction chamber 17, and a sealing cover 21 is hinged at the addition port.

[0049] like Figure 2 As shown, a gas storage tank 22 for storing inert gas (argon in this embodiment) is bolted to one side of the base 2; the upper side wall of the premixing box 3 is connected to the top of the gas storage tank 22, and a first one-way valve 23 for supplying gas to the upper part of the premixing box 3 is connected at the connection point; a condenser pipe 24 is connected to the upper side wall of the premixing box 3, and a second one-way valve 25 for supplying exhaust gas to the upper part of the premixing box 3 is connected at the connection point; the end of the condenser pipe 24 away from the premixing box 3 is connected to the reaction chamber 17.

[0050] like Figure 2 As shown, the condenser tube 24 is spiral-shaped; the spiral condenser tube 24 can increase its own volume and surface area (length is increased by about 50%, heat exchange area is increased by about 40%), increase its own capacity and condensation range, thereby increasing the condensation time and condensation effect of inert gas, and improving the cooling effect of inert gas on whitening raw materials.

[0051] Specifically, the homogenized whitening raw material is transported to the reaction chamber 17 by the ultra-high pressure homogenizer 1. When the main gear 10 rotates, it drives the stirring shaft 18 and stirring rod 19 to rotate, thereby stirring the whitening raw material (stirring speed is about 150 rpm), improving the uniformity and reaction efficiency of the whitening raw material. During this process, the operator can open the sealing cover 21 and add the crosslinking agent through the addition port. Under the stirring action of the stirring shaft 18 and stirring rod 19, the whitening raw material will be fully mixed with the crosslinking agent, further improving the reaction efficiency and forming a microencapsulated semi-finished product.

[0052] like Figure 3 and Figure 4 As shown, the upper part of the support pipe 12 has several exhaust holes 26, which are all located inside the premixing box 3; the lower part of the support pipe 12 has air inlets, which are connected to the air storage tank 22. The connection between the two is connected to a third one-way valve 27 for supplying air to the lower part of the premixing box 3.

[0053] Specifically, during the vertical reciprocating sliding process of the premixing tank 3, whenever the premixing tank 3 slides upward, the space between the piston plate 7 and the upper part of the premixing tank 3 expands. At this time, the upper part of the premixing tank 3 will draw inert gas from the gas storage tank 22 through the first one-way valve 23 at a suction volume of about 0.5L / time. Whenever the premixing tank 3 slides downward, the space between the piston plate 7 and the upper part of the premixing tank 3 will compress. At this time, the upper part of the premixing tank 3 will deliver inert gas to the condenser tube 24 through the second one-way valve 25 at a flow rate of about 0.5L / time for condensation, and purge and cool the whitening raw materials in the reaction chamber 17 (the gas can be cooled to 5-10℃), ensuring the effectiveness of the active ingredients in the whitening raw materials (the loss of VC active ingredients is reduced by about 15%).

[0054] During this process, whenever the premix box 3 slides downward, the space between the piston plate 7 and the lower part of the premix box 3 expands. At this time, the lower part of the premix box 3 will draw inert gas from the gas storage tank 22 at a flow rate of about 0.5L / time. The inert gas will sequentially fill the lower part of the premix box 3 through the third one-way valve 27, the air inlet and the exhaust port 26 at a flow rate of about 0.5L / time, thereby ensuring that the premix box 3 can slide stably. At the same time, when the inert gas is discharged through the exhaust port 26, it will form an inert airflow and impact the whitening raw material, further improving the fluidity of the whitening raw material.

[0055] Before processing the whitening raw materials, the operator can also start the first drive unit 9 for 3-5 minutes and open the material receiving cover 20 at the same time, so that the premix box 3 moves vertically back and forth during rotation, thereby generating relative motion with the piston plate 7, continuously drawing inert gas from the gas storage tank 22, and using the inert gas to purge the entire device, so that the oxygen in the device is discharged through the material receiving cover 20, removing the oxygen in the device, thereby reducing the risk of oxidation of the whitening raw materials during subsequent processing.

[0056] This invention utilizes the design of the premixing chamber 3. The rotation of the premixing chamber 3 ensures the fluidity of the whitening raw materials, preventing solidification and ensuring the effectiveness of subsequent homogenization. Simultaneously, the vibration of the premixing chamber 3 causes the whitening raw materials to vibrate, effectively improving their uniformity and fluidity, further enhancing the homogenization effect. Through the relative movement of the piston plate 7 and the premixing chamber 3, the whitening raw materials are premixed and immediately transported to the ultra-high pressure homogenizer 1, ensuring timely delivery and preventing solidification or stratification due to prolonged transport time, which would otherwise affect the homogenization process.

[0057] In existing technologies, the production cost of skin whitening products is extremely high due to the need for multiple devices such as premixing equipment, transportation equipment, and ultra-high pressure homogenizing equipment. Furthermore, the transfer and pumping between different devices is not only time-consuming and energy-intensive, but also increases the contact time between the active ingredients in the skin whitening raw materials and oxygen and light, increasing the risk of oxidation and deterioration (approximately 150 minutes per process). This invention, through the design of the premixing tank 3, can achieve integrated premixing, transportation, and homogenization of skin whitening raw materials without the need for additional premixing and transportation equipment, effectively reducing the production cost of skin whitening products. Premixing the skin whitening raw materials using the premixing tank 3 maintains their fluidity and uniformity, improving the processing effect of subsequent homogenization. While premixing the skin whitening raw materials, the device can also automatically transport them. Through integrated design, the pretreatment, transportation, homogenization, and microencapsulation of skin whitening raw materials are successfully achieved, effectively reducing the risk of oxidation and deterioration and shortening the preparation time (approximately 75 minutes per process), thus improving the efficiency and quality of skin whitening product production.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
