Description

Technical Field

[0001] This invention relates to the field of pharmaceutical manufacturing technology, and in particular to a mixing mixer and manufacturing process for the production of vitamin D drops. Background Technology

[0002] In the health food and pharmaceutical industry, vitamin D drops are a widely used nutritional supplement. Their production process places extremely stringent requirements on dosage accuracy, content uniformity, and product stability. Vitamin D, as the core active ingredient, is added in minute quantities but has extremely high biological activity; any slight deviation in content can affect the product's potency and safety. Therefore, industrial production commonly employs a pre-dispersion process, where a high concentration of vitamin D raw material is pre-concentrated in a small amount of carrier oil to prepare a homogeneous "vitamin mother liquor," which is then finally diluted in large-scale mixing tanks. This process is the cornerstone of ensuring the precise dosage of every drop in the final product.

[0003] Sanitary mixing tanks are core equipment for the efficient and high-quality preparation of mother liquor, requiring controlled environments such as light protection and nitrogen purging to achieve extremely uniform dispersion of trace components. However, the stirring systems of commonly used mixing tanks in the industry currently have significant shortcomings. On the one hand, they mostly use single fixed-diameter impellers (such as paddle or anchor impellers), resulting in a strong directional flow field during operation. This easily creates dead zones in areas such as the bottom corners of the tank and near the stirring shaft, leading to uneven mixing of vitamin raw materials, prolonged stirring time, and the risk of batch-to-batch content fluctuations. On the other hand, the dead zones and inefficient flow fields weaken heat transfer efficiency, causing the mother liquor to heat up slowly. To compensate for insufficient mixing, increasing the stirring speed or extending the time not only increases energy consumption but may also threaten the production stability of vitamin D products due to excessive mechanical shearing and heat generation.

[0004] In summary, the problems of mixing dead zones and inefficient heat transfer in existing mixing systems have become bottlenecks restricting the efficiency, energy consumption, and quality consistency of vitamin D drug production and D drop production. Developing a new mixing technology that enables efficient and uniform mixing throughout the entire tank area is of great significance. Summary of the Invention

[0005] Given the problems of existing technologies, such as dead zones during stirring leading to uneven mixing and slow heating, which prolongs processing time and increases energy consumption, a mixing mixer based on the production of vitamin D drops is proposed.

[0006] The purpose is to install a baffle plate that can be radially reciprocated on the rotating shaft. The movement of the baffle plate creates a non-directional flow field in the tank, eliminating dead zones in the stirring. At the same time, the baffle plate transfers heat to the liquid, increasing the liquid's heating rate.

[0007] The technical solution of this invention is a mixing mixer for the production of vitamin D drops, including a mixing tank and a rotating shaft driven by a motor. A stirring blade is fixedly installed on the shaft wall. The machine also includes a rotating seat movably sleeved on the shaft wall. T-shaped limiting seats are provided on both the upper and lower sides of the rotating seat, and these limiting seats are fixedly sleeved on the shaft wall. A connecting ring is connected above the rotating seat, and the connecting ring engages with the upper limiting seat. A U-shaped plate is fixedly connected to the side wall of the rotating seat. A slider is slidably connected to the lower part of the U-shaped plate, and a baffle is fixedly connected to the bottom of the slider. A sliding plate is slidably connected to the upper part of the U-shaped plate, and a chain is installed at the bottom of the sliding plate. The chain drives the slider to slide back and forth. A toothed ring is sleeved on the upper end of the rotating shaft. Two pneumatic push rods are connected between the toothed ring and the mixing tank. An air pipe is connected between the air holes of the two pneumatic push rods, and the air pipe extends out of the mixing tank and connects to an external air pump. A gear is meshed on one side of the toothed ring, and the gear drives the chain to rotate. The spoiler and the U-shaped plate are set at an acute angle along their length direction, and the spoiler has a hollow structure. Both sides of the upper end of the spoiler are provided with through holes, and an air guide hood is provided on one of the through holes. The air guide hood is fixedly connected to the spoiler.

[0008] Furthermore, the chain has two sprockets meshing with each other, the sprockets are rotatably connected to the slide plate, a lever is fixedly connected to the outside of the chain, the top of the slider has a groove, and the lower end of the lever slides in cooperation with the groove.

[0009] Furthermore, the sprocket near the toothed ring passes axially upward through the U-shaped plate and is fixedly connected to the gear.

[0010] Furthermore, multiple baffles are fixedly installed inside the spoiler, and the baffles and the cavity of the spoiler cooperate to form an S-shaped channel, with the two ends of the S-shaped channel communicating with two through holes of the spoiler respectively.

[0011] Furthermore, multiple connecting plates are fixedly connected to the bottom of the connecting ring, the connecting plates are slidably connected to the rotating seat, multiple elastic elements are connected between the connecting ring and the rotating seat, multiple positioning holes are opened in a ring at equal intervals on the connecting ring, and multiple positioning posts are fixedly connected to the upper limiting seat, the positioning posts are set in the corresponding positioning holes; The bottom of the toothed ring is equipped with guide wheels at equal intervals in a ring shape, and the guide wheels make rolling contact with the top surface of the connecting ring.

[0012] Furthermore, an oblique hole is provided on the connecting plate adjacent to the slide plate, and a drive rod is fixedly connected to one end of the slide plate near the rotating seat. The drive rod is slidably connected to the oblique hole.

[0013] Furthermore, a guide ring is fixedly connected to the upper part of the inner wall of the mixing tank, and an annular groove is opened on the guide ring. The end of the U-shaped plate away from the rotating seat is slidably disposed in the annular groove.

[0014] Furthermore, the end of the slide plate near the guide ring is provided with anti-slip texture, and an anti-slip ring is provided in the annular groove.

[0015] Another objective of this invention is to provide a production process based on vitamin D drops, the purpose of which is that: while the rotating shaft drives the baffle to rotate, the baffle moves radially back and forth, avoiding the formation of a directional flow field in the tank, eliminating dead zones in the stirring and increasing the liquid heating rate.

[0016] To achieve the above objectives, the present invention provides the following technical solution: a production process for vitamin D drops, comprising the following steps: S1. Preparation of mother liquor: A small amount of refined carrier oil and vitamin D raw material are added to the mixing tank. Under the action of heating, stirring blades and baffles, the raw material is rapidly heated and mixed to form vitamin mother liquor. S2. Mixing of main ingredients: Add the remaining carrier oil and vitamin mother liquor into the mixing tank, fill the tank with high-purity nitrogen, and rotate the stirring system at high speed to mix the materials evenly. S3. Filtration and degassing: The homogenized liquid is filtered through a precision filter to remove any possible small particulate impurities, and then degassed under vacuum to remove any possible air bubbles. S4. Filling and Packaging: The fully automatic liquid filling machine accurately fills a fixed amount of medicine into the prepared dropper bottle, seals the bottle cap, checks the product for any abnormalities using a light inspection device, and finally affixes the label.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the rotating shaft drives the U-shaped plate to rotate, the baffle plate rotates with the shaft and moves back and forth along the U-shaped plate. The movement of the baffle plate disrupts the original directional circumferential flow of the stirring blades, forming a non-directional three-dimensional turbulence. This enhances the axial and radial exchange rate of the liquid in low-speed areas such as the inner wall and bottom corners of the mixing tank. At the same time, the baffle plate itself is a mobile radiator, actively carrying and transferring heat to the central area of ​​the mixing tank, increasing the liquid heating rate, thereby improving the mixing efficiency.

[0018] 2. By controlling the lifting and lowering operation of the gear ring, the connection status between the gear ring and the gear and connecting ring can be controlled. When the gear ring is not in contact with the gear and connecting ring, the linkage load between the rotating shaft and the U-shaped plate and the baffle is eliminated, reducing the operating energy consumption. At the same time, the baffle is statically attached to the inner wall of the mixing tank. During high-speed stirring, no additional power is needed to drive its operation. The baffle can achieve the turbulence effect simply by the liquid flow, further reducing the overall energy consumption of the equipment and improving energy utilization efficiency.

[0019] 3. The high surface velocity and constantly changing direction of the baffle during movement make it difficult for high-viscosity vitamin mother liquor to adhere stably and accumulate on its surface. This dynamic characteristic reduces material residue and makes it easier to be thoroughly rinsed by the cleaning medium after the batch ends, meeting the stringent requirements of the pharmaceutical industry to prevent cross-contamination.

Detailed Implementation

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1, referring to Figures 1-4 This invention provides a mixing mixer for the production of vitamin D drops, comprising a mixing tank 1 and a rotating shaft 2 driven by a motor. A stirring blade 3 is fixedly mounted on the shaft wall of the rotating shaft 2. The machine also includes a rotating seat 4 movably sleeved on the shaft wall of the rotating shaft 2. T-shaped limiting seats 5 are provided on both the upper and lower sides of the rotating seat 4, and the limiting seats 5 are fixedly sleeved on the shaft wall of the rotating shaft 2. A connecting ring 20 is connected above the rotating seat 4, and the connecting ring 20 engages with the limiting seat 5 located on the upper side. A U-shaped plate 6 is fixedly connected to the side wall of the rotating seat 4. A slider 7 is slidably connected to the lower part of the U-shaped plate 6, and a baffle 8 is fixedly connected to the bottom of the slider 7. A baffle 8 is slidably connected to the upper part of the U-shaped plate 6. There is a slide plate 10, and a chain 9 is installed at the bottom of the slide plate 10. The chain 9 is used to drive the slider 7 to slide back and forth. A toothed ring 13 is sleeved on the upper end of the rotating shaft 2. The toothed ring 13 and the mixing tank 1 are connected together by two pneumatic push rods 14. The air holes of the two pneumatic push rods 14 are connected together by an air pipe 15. The air pipe 15 passes through the mixing tank 1 and is connected to an external air pump. A gear 16 is meshed on one side of the toothed ring 13. The gear 16 is used to drive the chain 9 to rotate. The spoiler 8 and the U-shaped plate 6 are set at an acute angle in the length direction. The spoiler 8 has a cavity structure. Through holes are opened on both sides of the upper end of the spoiler 8. A wind guide shroud 17 is installed on one of the through holes. The wind guide shroud 17 is fixedly connected to the spoiler 8.

[0024] Specifically, the motor drives the rotating shaft 2 and stirring blade 3 to rotate simultaneously, as well as the rotating seat 4 and U-shaped plate 6 to rotate synchronously. The gear 16 revolves around the gear ring 13 and rotates on its own axis. The chain 9 drives the slider 7 and the baffle 8 to slide back and forth along the length of the U-shaped plate 6. The inclined baffle 8 pushes the liquid to move radially within the tank, breaking the directional circular flow field generated by the stirring blade 3 and forming three-dimensional turbulence. During this process, the inclined baffle 8 continuously pushes the liquid to move radially, effectively breaking the directional circular flow field generated by the stirring blade 3 and forming three-dimensional turbulence within the tank. This motion significantly enhances the fluidity of the liquid near the inner wall of the mixing tank 1, improving the exchange and mixing efficiency of the liquid throughout the entire tank area. At the same time, the air guide shroud 17 can guide the heated air in the upper part of the mixing tank 1 to the interior of the baffle 8, utilizing its high-temperature surface to fully contact the liquid at different locations, further enhancing the overall heating effect of the liquid and achieving a simultaneous improvement in mixing uniformity and heat transfer efficiency.

[0025] The baffle 8 moves in a spiral path under the action of the rotating shaft 2 and the chain 9. On the one hand, as the baffle 8 slides back and forth, it continuously applies radial thrust to the liquid. This action disrupts the directional circumferential flow field generated by the stirring blades 3, producing strong eddies, shearing, and turbulence. This forces the liquid to move violently in the radial, axial, and circumferential directions, forming complex three-dimensional turbulence, which greatly improves the fluid motion state of the entire tank area and significantly enhances the axial and radial exchange rate of the liquid in low-speed areas such as the inner wall and bottom corners of the mixing tank 1. This ensures that trace amounts of vitamin D can be dispersed more quickly and thoroughly into the entire carrier oil, fundamentally reducing the risk of uneven mixing and providing a key guarantee for the accuracy of dosage and uniformity of content in the final product. At the same time, the baffle 8 as a whole becomes a movable "radiator". Unlike the passive conduction of static heating, the moving baffle 8 actively carries heat and directly transfers it to the liquid in different temperature areas, especially the central area of ​​the mixing tank 1, which usually has poor heat transfer. This "heat delivery" mechanism greatly enhances the heat transfer process, enabling rapid and synchronous heating of the vitamin mother liquor, effectively shortening the production cycle, and reducing the risk of degradation of heat-sensitive vitamins due to prolonged local heating.

[0026] In the initial mixing stage, vitamin powder or concentrate requires high shear force for rapid dispersion and dissolution. At this time, the combined motion of the baffle 8 generates a strong and variable shear force field throughout the entire tank, especially near its acute edges, which can efficiently break up particles and clumps. Once the material is initially dispersed, excessive shear force may be detrimental. By reducing the motor speed, a gentler mixing mode can be switched to protect the stability of the dispersed system while further reducing energy consumption.

[0027] An external air pump can supply or extract air to the pneumatic push rod 14 through the air pipe 15, thereby controlling the height of the gear ring 13. During the initial slow stirring, the gear ring 13 meshes with the gear 16, and the baffle 8 moves radially back and forth while rotating with the shaft 2. During the later rapid stirring, the pneumatic push rod 14 drives the gear ring 13 to rise, the gear ring 13 disengages from the gear 16, and the baffle 8 stops moving radially, thereby reducing rotational resistance, improving stirring efficiency, and reducing energy consumption.

[0028] Understandably, the mixing tank 1 is equipped with a heating jacket. When the heating is turned on, the tank body and the air above it are rapidly heated. Since the air heating rate is much greater than the liquid heating rate, the baffle 8 continuously absorbs the hot air above into its own cavity as it rotates, and transfers the heat to the liquid. Through the continuous ventilation of the two through holes, the baffle 8 is kept at a temperature close to that of the air, effectively heating the liquid.

[0029] Reference Figure 3 , Figure 4The chain 9 has two sprockets meshing inside, and the sprockets are rotatably connected to the slide plate 10. The chain 9 has a lever 11 fixedly connected to the outside. The top of the slider 7 has a groove 12, and the lower end of the lever 11 slides in cooperation with the groove 12.

[0030] Specifically, when the rotating seat 4 drives the U-shaped plate 6 to rotate, the gear 16 on the U-shaped plate 6 will make circular motion around the fixed gear ring 13. During this process, the gear 16 rotates due to the meshing action of the gear ring 13, which in turn drives the sprocket coaxially connected to the gear 16 to rotate. The sprocket then drives the chain 9 to rotate synchronously. As the chain 9 rotates cyclically, the lever 11 fixed on its outer side will move accordingly. The lower end of the lever 11 is embedded in the groove 12 on the top of the slider 7 and slides with it, which can convert the circular motion of the chain 9 into the reciprocating motion of the slider 7 in a straight line, and finally drive the spoiler 8 connected to the slider 7 to move back and forth.

[0031] Reference Figure 4 The sprocket on the side closest to the gear ring 13 passes upward through the U-shaped plate 6 and is connected and fixed to the gear 16.

[0032] Specifically, the sprocket on the side near the gear ring 13 extends upward through a connecting shaft, passes through the corresponding through hole of the U-shaped plate 6, and is coaxially connected and fixed to the gear 16. When the rotating seat 4 drives the U-shaped plate 6 to rotate around the central axis, the U-shaped plate 6 will carry the gear 16 to make a synchronous circular motion. At this time, the gear 16 is engaged with the fixed gear ring 13. During the revolution, it is driven by the teeth of the gear ring 13 to rotate, and then drives the sprocket below to rotate synchronously through the connecting shaft.

[0033] Reference Figure 4 , Figure 5 Multiple baffles 18 are fixedly installed inside the spoiler 8. The baffles 18 and the cavity of the spoiler 8 cooperate to form an S-shaped channel 19. The two ends of the S-shaped channel 19 are respectively connected to two through holes of the spoiler 8.

[0034] Specifically, the S-shaped channel 19 significantly extends the flow path of hot air, increases heat exchange time, and improves heat utilization. Simultaneously, it ensures uniform heat transfer to all areas of the baffle 8, avoiding localized temperature differences and ensuring uniform heating upon contact with the vitamin mother liquor. During its reciprocating movement, the baffle 8 synchronously transfers heat evenly to the surrounding materials, accelerating the overall heating of the mother liquor in conjunction with the turbulence effect, further shortening the heating cycle and reducing the loss of activity of heat-sensitive components due to prolonged heating.

[0035] The S-shaped channel 19 features a chamfered bend at the turn, which facilitates rapid airflow reversal, improves airflow smoothness, and reduces noise.

[0036] It should be noted that the spoiler 8 is made of a metal material (such as copper or aluminum) that has high thermal conductivity and does not react with vitamin raw materials.

[0037] Example 2, refer to Figure 6 , Figure 7 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: multiple connecting plates 21 are fixedly connected to the bottom of the connecting ring 20, the connecting plates 21 are slidably connected to the rotating seat 4, multiple elastic elements 22 are connected between the connecting ring 20 and the rotating seat 4, multiple positioning holes 23 are opened in a ring at equal intervals on the connecting ring 20, and multiple positioning posts 24 are fixedly connected to the upper limiting seat 5, and the positioning posts 24 are set in the corresponding positioning holes 23; guide wheels 25 are installed in a ring at equal intervals at the bottom of the toothed ring 13, and the guide wheels 25 are in rolling contact with the top surface of the connecting ring 20.

[0038] Specifically, when the gear ring 13 and gear 16 are engaged, the gear ring 13 applies downward pressure to the connecting ring 20 through the guide wheel 25 at the bottom, pushing the connecting ring 20 downward along the sliding fit direction between the connecting plate 21 and the rotating seat 4, so that the positioning pin 24 on the upper limit seat 5 is precisely inserted into the corresponding positioning hole 23 of the connecting ring 20. At this time, the elastic element 22 between the connecting ring 20 and the rotating seat 4 is in a compressed state. Through the engagement of the positioning pin 24 and the positioning hole 23, the power of the rotating shaft 2 can be transmitted to the rotating seat 4 and the U-shaped plate 6 in sequence to achieve synchronous rotation and ensure stable meshing transmission between the gear 16 and the gear ring 13.

[0039] When the gear ring 13 rises and disengages from the gear 16, the pressure of the guide wheel 25 on the connecting ring 20 disappears, the elastic element 22 releases its elastic potential energy and pushes the connecting ring 20 upward, causing the positioning pin 24 to disengage from the positioning hole 23, and the connecting ring 20 to disengage from the limiting seat 5. At this time, the rotating shaft 2 only drives the stirring blade 3 to rotate, and the rotating seat 4 and U-shaped plate 6 no longer move synchronously with the rotating shaft 2, effectively avoiding the following rotation of idle transmission components, significantly reducing the running resistance of the rotating shaft 2, and reducing power loss.

[0040] Reference Figure 8 An oblique hole 26 is provided on the connecting plate 21 adjacent to the slide plate 10. A drive rod 27 is fixedly connected to one end of the slide plate 10 near the rotating seat 4. The drive rod 27 is slidably connected to the oblique hole 26.

[0041] Specifically, when the connecting ring 20 rises, the inclined hole 26 cooperates with the driving rod 27 to push the slide plate 10 to slide away from the rotating seat 4, so that the gear 16 cancels its engagement with the gear ring 13.

[0042] When the baffle 8 is close to the inner wall of the mixing tank 1 and the gear 16 and the gear ring 13 are not meshed, the baffle 8 is fixedly attached to the inner wall of the mixing tank 1, forming an acute angle with the interior of the mixing tank 1. Under this configuration, when the liquid flows through the side wall of the baffle 8, it generates strong eddies, shearing, and turbulence effects, further accelerating the flow velocity and thus improving the overall mixing effect. At the same time, a local high-shear zone is formed around the baffle 8, and the shear force in this area can effectively break up tiny fat particles or aggregates. If solid raw materials (such as some vitamin powder) need to be dissolved during the mixing process, this structure can significantly accelerate the dissolution process, further promoting the full integration of vitamin raw materials and carrier oil.

[0043] Through the linkage design of the gear ring 13, gear 16, and connecting ring 20, when the gear ring 13 rises and cancels its meshing with gear 16 and its downward pressure on the connecting ring 20, on the one hand, the transmission friction between gear 16 and gear ring 13 and the linkage load between shaft 2, U-shaped plate 6, and baffle 8 are eliminated, directly reducing the resistance when the stirring blade 3 rotates rapidly and avoiding ineffective energy consumption; on the other hand, the baffle 8 is in a static state against the inner wall of the mixing tank 1, requiring no additional power to drive its operation, and the baffle effect is achieved solely through liquid flow, further reducing the overall energy consumption of the equipment and improving energy utilization efficiency. The remaining structure is the same as that in Embodiment 1.

[0044] Example 3, referring to Figure 2 , Figure 9 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that a guide ring 28 is fixedly connected to the upper part of the inner wall of the mixing tank 1, and an annular groove 29 is opened on the guide ring 28. The end of the U-shaped plate 6 away from the rotating seat 4 is slidably disposed in the annular groove 29.

[0045] Specifically, the annular groove 29 forms a wrap-around limit on the end of the U-shaped plate 6 away from the rotating seat 4. This limiting structure can restrict the offset of the U-shaped plate 6 in the non-rotational direction, ensuring that the trajectory of the U-shaped plate 6 is stable when it rotates around the rotating seat 4. At the same time, it provides a smooth guide for the spoiler 8 to move with the U-shaped plate 6, avoiding jamming or offset during the movement of the spoiler 8.

[0046] The guide ring 28 is composed of two semi-circular materials, and the upper side of the guide ring 28 is connected and fixed to the mixing tank 1 by bolts.

[0047] Reference Figure 8 , Figure 9 The end of the slide plate 10 near the guide ring 28 is provided with anti-slip texture 30, and the annular groove 29 is provided with anti-slip ring 31.

[0048] Specifically, when the connecting ring 20 rises and pushes the slide plate 10 towards the guide ring 28, the anti-slip texture 30 at the end of the slide plate 10 gradually comes into contact with and tightly abuts against the anti-slip ring 31 in the annular groove 29. Through the friction between the anti-slip texture 30 and the anti-slip ring 31, the sliding fit between the U-shaped plate 6 and the guide ring 28 is transformed into a fixed connection. At the same time, the other end of the U-shaped plate 6 is limited by the rotating shaft 2. Under this double constraint, the U-shaped plate 6 can remain stationary and avoid rotating synchronously with the rotating shaft 2. The rest of the structure is the same as that of Embodiment 2.

[0049] Based on embodiments 1-3, the working principle of this invention is as follows: A fixed amount of carrier oil and a fixed amount of vitamin D raw material are added to the mixing tank 1 and the heating is turned on. The motor drives the rotating shaft 2 to rotate the stirring blade 3. At the same time, through the cooperation of the limiting seat 5 and the connecting ring 20, the rotating seat 4 and the U-shaped plate 6 are rotated synchronously. During the initial low-speed stirring, the pneumatic push rod 14 controls the toothed ring 13 to descend and mesh with the gear 16. The gear 16 drives the chain 9 to rotate. The lever 11 pushes the slider 7 to slide back and forth along the U-shaped plate 6 through the slide groove 12. The inclined baffle 8 breaks the circumferential flow field to form a three-dimensional turbulence, which accelerates the mixing efficiency of vitamin D and carrier oil. At the same time, hot air enters the S-shaped channel 19 of the baffle 8 through the air guide shroud 17, and the liquid is quickly heated by the heat-conducting material, which promotes the fusion of vitamin D raw material and carrier oil. During the later high-speed stirring, the pneumatic push rod 14 drives the gear ring 13 to rise, disengage from the gear 16 and release the downward pressure on the connecting ring 20. The elastic element 22 pushes the connecting ring 20 to move upward, so that the U-shaped plate 6 is fixed to the anti-slip ring 31 of the guide ring 28 through the anti-slip texture 30 of the sliding plate 10. The baffle plate 8 is stationary and attached to the tank wall, reducing the operating resistance.

[0050] Example 4, refer to Figures 1-9 The fourth embodiment of the present invention provides: a production process for vitamin D drops, comprising the following steps: S1. Preparation of mother liquor: A small amount of refined carrier oil and vitamin D raw material are added to the mixing tank 1. Under the action of heating and stirring blade 3 and baffle 8, the raw material is rapidly heated and mixed to form vitamin mother liquor. S2. Mixing of main ingredients: Add the remaining carrier oil and vitamin mother liquor into the mixing tank, fill the tank with high-purity nitrogen, and rotate the stirring system at high speed to mix the materials evenly. S3. Filtration and degassing: The homogenized liquid is filtered through a precision filter to remove any possible small particulate impurities, and then degassed under vacuum to remove any possible air bubbles. S4. Filling and Packaging: The fully automatic liquid filling machine accurately fills a fixed amount of medicine into the prepared dropper bottle, seals the bottle cap, checks the product for any abnormalities using a light inspection device, and finally affixes the label.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
