Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine concentration technology, and in particular to a device for extracting and separating components from traditional Chinese medicinal materials. Background Technology

[0002] Traditional Chinese medicine ointments generally refer to herbal pastes, which have the effects of nourishing, removing dampness, dispelling cold, promoting blood circulation and removing blood stasis, reducing swelling and relieving pain. Traditional Chinese medicine ointments need to go through steps such as cleaning, removing impurities, soaking, decocting, purifying and concentrating. Among them, the concentration equipment evaporates the Chinese medicine liquid by heating with steam to achieve the purpose of concentration. Evaporation and concentration is a key process for extracting effective ingredients and reducing the volume of the liquid. Currently, the commonly used evaporation and concentration equipment still has several problems that directly affect the concentration efficiency, product quality and equipment stability in actual operation.

[0003] In traditional evaporators, as the solvent evaporates during the concentration process, the liquid level inside the tank continuously decreases, reducing the contact area between the heated walls and the liquid. When the liquid level drops to a certain height, some heated areas become vacant or semi-vacant, significantly reducing heat transfer efficiency, resulting in a large waste of heat energy and increased production costs. Because the concentrated Chinese medicine liquid has a complex composition, containing various viscous components such as sugars, proteins, and tannins, the liquid gradually becomes viscous during the evaporation process. The viscous liquid is in prolonged contact with the container wall, which can cause the "Chinese medicine" to adhere to the heated surface, forming a "wall-hanging" phenomenon. This wall-hanging layer not only reduces heat transfer efficiency and exacerbates the risk of local overheating, but may also cause degradation or charring of the active ingredients, affecting the uniformity of drug quality.

[0004] In static or low-circulation-efficiency evaporators, the degree of heating and evaporation rate of the drug solution at different liquid levels vary, resulting in a significant concentration gradient between the upper and lower layers of the tank. This concentration difference leads to uneven distribution of the effective components in the final concentrate, affecting batch-to-batch quality consistency and increasing the difficulty of subsequent process control.

[0005] During the concentration of traditional Chinese medicine, bubbles can carry some of the concentrate to the inner wall of the tank and leave residues there. As the operation time increases, these residues gradually accumulate, forming a layer of dirt that is difficult to clean and becomes a potential breeding ground for microorganisms. This poses a threat to the hygiene and safety of the medicine and also increases the difficulty of cleaning and maintenance costs.

[0006] In summary, existing Chinese medicine evaporation and concentration equipment still has significant shortcomings in terms of heat energy utilization, anti-wall adhesion, concentration uniformity, and control of bubble residue. Therefore, a Chinese medicine component extraction and separation device is proposed. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, the present invention proposes a device for extracting and separating components of traditional Chinese medicine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a device for extracting and separating components of traditional Chinese medicine, comprising an evaporation mechanism, wherein the evaporation mechanism includes an inner evaporation tank and an outer evaporation tank sleeved on the outside of the inner evaporation tank, a heating chamber for heating the inside of the inner evaporation tank is formed between the inner evaporation tank and the outer evaporation tank, a tank cover is installed on the top of the inner evaporation tank, a discharge pipe is fixedly installed through the tank cover, a separation and collection mechanism for collecting vaporized solvent is connected to the discharge pipe, a gathering and dispersing mechanism is rotatably installed inside the inner evaporation tank to scrape the inner wall of the inner evaporation tank and gather the concentrated liquid of traditional Chinese medicine toward the center, and a lifting mechanism is rotatably installed at the center of the inner evaporation tank to lift the concentrated liquid of traditional Chinese medicine gathered at the center and bottom of the inner evaporation tank upward and throw it toward the inner wall of the inner evaporation tank; The lifting mechanism includes a cylinder coaxial with the inner evaporation tank, and the gathering and dispersing mechanism includes two vortex-shaped scrapers fixed on the outside of the cylinder and distributed in a centrally symmetrical manner. The two vortex-shaped scrapers are used to gradually gather and guide the concentrated Chinese medicine liquid near the inner wall of the inner evaporation tank into the cylinder and to scrape and clean the inner wall of the inner evaporation tank.

[0009] Preferably, the cylinder is provided with a shaft and spiral blades inside to convey the concentrated Chinese medicine liquid from the bottom of the evaporation tank upwards. The spiral blades are fixedly sleeved on the shaft. A motor for driving the cylinder and shaft to rotate is fixedly installed on the top of the tank cover. The top end of the shaft extends out of the cylinder and is connected to the output shaft of the motor. The gathering and dispersing mechanism also includes two rectangular tubes that output the concentrated Chinese medicine liquid inside the cylinder and coat it on the inner wall of the evaporation tank. The two rectangular tubes are embedded in the top of two vortex-shaped scrapers. Both rectangular tubes penetrate the cylinder and are fixedly connected to the cylinder.

[0010] Preferably, the separation and collection mechanism includes a separator and a collection tank. A condenser is provided at the top of the collection tank. A conduit four connects the separator and the condenser. A conduit one connects the separator and the discharge pipe. A conduit two connects to the conduit one. A conduit three connects to the bottom of the separator.

[0011] Preferably, a cover plate is fixedly installed on the inner wall of the evaporation tank, the cylinder penetrates the cover plate and is rotatably connected to the cover plate, the evaporation tank and the cover plate are connected through the same feed pipe, the discharge pipe penetrates the cover plate and is fixedly connected to the cover plate, the tops of the two vortex scrapers are attached to the bottom of the cover plate and are slidably connected to the bottom of the cover plate, and the bottom of the evaporation tank is fixedly connected to the discharge valve.

[0012] Preferably, the tops of both rectangular tubes are flush with the top of the vortex-shaped scraper, and the sides of the two rectangular tubes that are far apart from each other are slidably connected to the inner wall of the evaporation tank. The end of the rectangular tube away from the cylinder is provided with an outlet, which is located outside the vortex-shaped scraper. The bottom of the cylinder is provided with multiple feed ports arranged in a circumferential array. During the clockwise rotation of the two vortex-shaped scrapers, the concentrated Chinese medicine liquid that was originally close to the inner wall of the evaporation tank can be continuously gathered towards the cylinder. The concentrated Chinese medicine liquid gathered near the cylinder will enter the cylinder through the multiple feed ports, and the rotating spiral blades can continuously lift the concentrated Chinese medicine liquid inside the cylinder upwards, realizing a specific closed loop path of "bottom gathering → center lifting → upper centrifugal throwing out → wall gravity return".

[0013] Preferably, an annular baffle is rotatably sleeved on the shaft, the annular baffle is fixedly connected to the inner wall of the cylinder, and the top of the spiral blade is in contact with the bottom of the annular baffle.

[0014] Preferably, the bottom inner walls of both rectangular tubes are inclined, and the end of the rectangular tube closer to the cylinder is higher than the other end.

[0015] Preferably, the cylinder is provided with a transmission mechanism, which includes an outer gear ring fixedly installed inside the cylinder and an inner gear ring fixedly sleeved on a shaft. The outer gear ring and the inner gear ring are coaxially arranged and are connected by meshing of multiple gears arranged in a circumferential array. The top of the multiple gears is rotatably mounted on the same wheel frame. The shaft passes through the wheel frame and is rotatably connected to the wheel frame. The top of the wheel frame is fixedly connected to the can lid by multiple fixing rods arranged in a circumferential array.

[0016] Preferably, a reflux pipe is fixedly installed through the cover plate, the top end of the reflux pipe extends to the outside of the inner evaporation tank, and the bottom of the reflux pipe is flush with the bottom of the cover plate. The reflux pipe is connected to the conduit in three phases, and the outer evaporation tank is provided with an outlet pipe and an inlet pipe that communicate with the heating chamber.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention, through two rotating vortex-shaped scrapers, not only significantly reduces the adhesion of highly viscous drug components to the inner wall of the evaporation tank, effectively preventing wall adhesion and scaling, but also maintains the long-term stable high heat transfer efficiency of the equipment, reduces the risk of drug component damage caused by local overheating, ensures the uniformity of the color and composition of the concentrate, improves product yield and quality stability, and reduces the frequency and intensity of equipment cleaning.

[0018] This invention uses two vortex-shaped scrapers to gather the concentrated Chinese medicine liquid in the inner evaporation tank towards the center, and a lifting mechanism to transport the concentrated Chinese medicine liquid at the bottom of the inner evaporation tank upwards. Finally, two rectangular tubes throw the upward-transported concentrated Chinese medicine liquid against the inner wall of the inner evaporation tank, allowing the concentrated Chinese medicine liquid to be fully mixed during the concentration process in the inner evaporation tank. This effectively breaks down temperature and concentration gradients, ensuring that the concentration of effective components in the concentrated Chinese medicine liquid is highly uniformly distributed in the inner evaporation tank. This greatly improves the quality uniformity of the final concentrated product, reduces batch differences, and provides stable and reliable raw materials for subsequent formulation processes.

[0019] This invention effectively prevents air bubbles from adhering to and remaining on the inner wall of the can lid by using a cover plate in conjunction with two vortex-shaped scrapers. This significantly reduces hard-to-clean hygiene dead corners and lowers the risk of microbial contamination. At the same time, the extended cleaning cycle and reduced cleaning difficulty also improve the overall utilization rate of the equipment and ensure the continuity and safety of the production process.

Detailed Implementation

[0022] The technical solution of the present invention will now be clearly and completely described 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-9 As shown, the present invention provides a technical solution: a Chinese herbal medicine component extraction and separation device, including an evaporation mechanism 1, the evaporation mechanism 1 including an inner evaporation tank 11 and an outer evaporation tank 12 sleeved on the outside of the inner evaporation tank 11, a heating chamber 13 is formed between the inner evaporation tank 11 and the outer evaporation tank 12 to heat the inside of the inner evaporation tank 11, a tank cover 14 is installed on the top of the inner evaporation tank 11, a discharge pipe 15 is fixedly installed through the tank cover 14, a separation and collection mechanism 2 for collecting vaporized solvent is connected to the discharge pipe 15, a gathering and dispersing mechanism 3 is rotatably installed inside the inner evaporation tank 11 to scrape the inner wall of the inner evaporation tank 11 and gather the concentrated Chinese herbal medicine liquid towards the center, and a lifting mechanism 4 is rotatably installed at the center of the inner evaporation tank 11 to lift the concentrated Chinese herbal medicine liquid gathered at the center and bottom of the inner evaporation tank 11 upward and throw it towards the inner wall of the inner evaporation tank 11; The lifting mechanism 4 includes a cylinder 41 coaxial with the evaporation tank 11. The gathering and dispersing mechanism 3 includes two vortex-shaped scrapers 31 fixed on the outside of the cylinder 41 and distributed in a centrally symmetrical manner. The two vortex-shaped scrapers 31 are used to gradually gather and guide the concentrated Chinese medicine liquid close to the inner wall of the evaporation tank 11 into the cylinder 41 and to scrape and clean the inner wall of the evaporation tank 11.

[0024] The cylinder 41 is equipped with a shaft 42 and a spiral blade 43 for conveying the concentrated Chinese medicine liquid at the bottom of the evaporation tank 11 upwards. The spiral blade 43 is fixedly sleeved on the shaft 42. The top of the tank cover 14 is fixedly installed with a motor 110 that drives the cylinder 41 and the shaft 42 to rotate. The top end of the shaft 42 extends to the outside of the cylinder 41 and is connected to the output shaft of the motor 110. The gathering and dispersing mechanism 3 also includes two rectangular tubes 32 that output the concentrated Chinese medicine liquid inside the cylinder 41 and coat it on the inner wall of the evaporation tank 11. The two rectangular tubes 32 are embedded and fixedly fixed into the top of two vortex scrapers 31. Both rectangular tubes 32 penetrate the cylinder 41 and are fixedly connected to the cylinder 41.

[0025] Furthermore, the integrated structural design of the vortex-shaped scraper 31, the rectangular tube 32, and the cylinder 41, such as... Figures 2-6 As shown, when the cylinder 41 rotates clockwise, the ends of the two vortex-shaped scrapers 31 away from the center can perform "wall cleaning" on the inner wall of the evaporation tank 11. Furthermore, due to the special shape and structure of the vortex-shaped scrapers 31, the vortex-shaped scrapers 31 can gather the concentrated Chinese medicine liquid close to the inner wall of the evaporation tank 11 towards the cylinder 41 at the center during clockwise rotation, achieving the purpose of "liquid flow gathering". After the concentrated Chinese medicine liquid gathered in the cylinder 41 enters the cylinder 41, it can be transported upward by the rotating spiral blades 43, and finally thrown outward through the two rectangular tubes 32 and fall back onto the inner wall of the evaporation tank 11. The thrown-out concentrated Chinese medicine liquid slides down the inner wall of the evaporation tank 11 under its own gravity and is coated on the inner wall of the evaporation tank 11, achieving the purpose of "centrifugal coating" of the concentrated Chinese medicine liquid. like Figure 5 As shown, the vortex-shaped scraper 31 can generate centrifugal force by rotating counterclockwise, which can remove the medicine attached to itself.

[0026] The separation and collection mechanism 2 includes a separator 21 and a collection tank 27. A condenser 25 is provided on the top of the collection tank 27. A conduit 26 connects the separator 21 and the condenser 25. A conduit 22 connects the separator 21 and the discharge pipe 15. A conduit 23 connects to the conduit 22. A conduit 24 connects to the bottom of the separator 21.

[0027] A reflux pipe 16 is fixedly installed through the cover plate 18. The top end of the reflux pipe 16 extends to the outside of the inner evaporation tank 11, and the bottom of the reflux pipe 16 is flush with the bottom of the cover plate 18. The reflux pipe 16 is connected to the conduit 24. The outer evaporation tank 12 is provided with an outlet pipe 121 and an inlet pipe 122 that are connected to the heating chamber 13.

[0028] In practice, the concentrated Chinese medicine liquid is injected into the inner evaporation tank 11 through the feed pipe 17, and then circulating steam is injected into the outer evaporation tank 12 through the air inlet pipe 122. The steam can heat the concentrated Chinese medicine liquid in the inner evaporation tank 11. After that, the steam is discharged through the air outlet pipe 121. After the concentrated Chinese medicine liquid is heated, the solvent in it evaporates and vaporizes and is discharged through the discharge pipe 15 and enters the separator 21 through the conduit 22. The separator 21 can separate the droplets / bubbles in the vaporized solvent to prevent the loss of "Chinese medicine" {"material run-out"}. Then the vaporized solvent enters the condenser 25 through the conduit 26. The condenser 25 can cool the vaporized solvent discharged from the separator 21 and liquefy it back into liquid. The liquefied solvent in the condenser 25 will fall into the collection tank 27 and be collected. The condenser 25 is a shell-and-tube condenser or a coil condenser. The cooling medium is usually cold water or ice water.

[0029] Furthermore, the separator 21 may be a baffle / plate separator or a wire mesh demister / foam catcher, and the condenser 25 may be a shell-and-tube condenser or a coil condenser. The cooling medium is usually cold water or ice water. The separator 21 and the condenser are common existing equipment and will not be described in detail here.

[0030] Furthermore, the droplets / bubbles intercepted in the separator 21 will flow into the conduit 24 under the action of gravity, and then re-enter the evaporation tank 11 through the return pipe 16.

[0031] Furthermore, during the evaporation of the concentrated Chinese medicine liquid inside the evaporation tank 11, the cover plate 18 can limit the height of the bubbles. For the bubbles attached to the bottom of the cover plate 18, the bubbles can be scraped off during the rotation of the two vortex scrapers 31. During the evaporation process, some bubbles will enter the separator 21 through the discharge pipe 15 and the first conduit 22, be intercepted by the separator 21, and flow back into the evaporation tank 11 through the third conduit 24. Through the cooperation of the cover plate 18 and the two vortex scrapers 31, the adhesion and residue of bubbles on the inner wall of the top of the tank cover 14 are effectively prevented, greatly reducing the hard-to-clean hygiene dead corners and reducing the risk of microbial contamination.

[0032] Furthermore, after concentration is complete, clean water can be injected into the inner evaporation tank 11 through conduit 23 for cleaning, such as... Figures 2-5 As shown, when cleaning the inside of the evaporation tank 11, the two vortex-shaped scrapers 31 are controlled to rotate. During this process, the vortex-shaped scrapers 31 can clean themselves, the inner wall of the evaporation tank 11, and the bottom of the cover plate 18.

[0033] like Figures 2-7As shown, a transmission mechanism 5 is provided inside the cylinder 41. The transmission mechanism 5 includes an external gear ring 53 fixedly installed inside the cylinder 41 and an internal gear ring 54 fixedly sleeved on the shaft 42. The external gear ring 53 and the internal gear ring 54 are coaxially arranged and are connected by meshing of multiple gears 52 arranged in a circumferential array. The top of the multiple gears 52 is rotatably mounted on the same wheel frame 51. The shaft 42 passes through the wheel frame 51 and is rotatably connected to the wheel frame 51. The top of the wheel frame 51 is fixedly connected to the can cover 14 by multiple fixing rods 55 arranged in a circumferential array.

[0034] In actual operation, the rotation of motor 110 will drive the shaft 42 to rotate, the rotation of shaft 42 will drive the spiral blade 43 to rotate, the rotation of shaft 42 will also drive the internal gear ring 54 to rotate, the rotation of internal gear ring 54 will drive the external gear ring 53 to rotate through multiple gears 52, the external gear ring 53 will then drive the cylinder 41 to rotate, and the rotation of cylinder 41 will drive the two vortex scrapers 31 to rotate synchronously.

[0035] Furthermore, through the cooperation of the internal gear ring 54, the external gear ring 53 and multiple gears 52, a speed difference can be created between the external gear ring 53 and the internal gear ring 54, and the speed of the external gear ring 53 is lower than that of the internal gear ring 54. That is, the speed of the shaft 42 and the spiral blade 43 is higher than that of the cylinder 41 and the two vortex scrapers 31. By adopting the built-in differential transmission mechanism 5, the speed of the spiral blade 43, which is a lifting component, is higher than that of the vortex scraper 31, which is a wall scraping component.

[0036] Furthermore, the concentrated Chinese medicine liquid has a complex composition, containing various viscous components such as sugars, proteins, and tannins. During the evaporation process, the liquid gradually becomes viscous. Prolonged contact between the viscous liquid and the inner wall of the evaporation tank 11 can easily cause the concentrated Chinese medicine liquid to adhere to the heating surface, forming a wall-hanging phenomenon. The two rotating vortex-shaped scrapers 31 not only scrape off the highly viscous liquid components adhering to the inner wall of the evaporation tank 11, effectively preventing the highly viscous liquid components from adhering to the inner wall and forming scale, but also maintain the long-term stable high heat transfer efficiency of the entire equipment, reducing the risk of damage to the medicinal components caused by overheating due to prolonged contact between the concentrated Chinese medicine liquid and the inner wall of the evaporation tank 11. They also ensure the uniformity of the color and composition of the concentrated liquid, improve the product yield and quality stability, and reduce the frequency and intensity of equipment cleaning.

[0037] like Figures 2-8As shown, a cover plate 18 is fixedly installed on the inner wall of the evaporation tank 11. The cylinder 41 passes through the cover plate 18 and is rotatably connected to the cover plate 18. The same feed pipe 17 is fixedly connected through the evaporation tank 11 and the cover plate 18. The discharge pipe 15 passes through the cover plate 18 and is fixedly connected to the cover plate 18. The tops of the two vortex scrapers 31 are attached to the bottom of the cover plate 18 and are slidably connected to the bottom of the cover plate 18. The bottom of the evaporation tank 11 is fixedly connected through the discharge valve 19.

[0038] The tops of the two rectangular tubes 32 are flush with the top of the vortex scraper 31. The sides of the two rectangular tubes 32 that are far apart from each other are slidably connected to the inner wall of the evaporation tank 11. The end of the rectangular tube 32 that is far away from the cylinder 41 is provided with an outlet 321. The outlet 321 is located outside the vortex scraper 31. The bottom of the cylinder 41 is provided with multiple feed ports 411 arranged in a circumferential array.

[0039] The top end of the shaft 42 extends outside the cylinder 41 and is connected to the end of the output shaft of the motor 110 that extends into the can cover 14 via a coupling.

[0040] An annular baffle 44 is rotatably sleeved on the shaft 42. The annular baffle 44 is fixedly connected to the inner wall of the cylinder 41, and the top of the spiral blade 43 is in contact with the bottom of the annular baffle 44.

[0041] In actual operation, when the cylinder 41 rotates clockwise, the ends of the two vortex-shaped scrapers 31 away from the center will rotate against the inner wall of the evaporation tank 11. During this process, the two vortex-shaped scrapers 31 can scrape off the concentrated Chinese medicine liquid attached to the inner wall of the evaporation tank 11, and the scraped-off concentrated Chinese medicine liquid will fall under the action of gravity. During the clockwise rotation of the two vortex scrapers 31, the concentrated Chinese medicine liquid that was originally close to the inner wall of the evaporation tank 11 can be continuously gathered towards the cylinder 41. The concentrated Chinese medicine liquid gathered near the cylinder 41 will enter the cylinder 41 through multiple feed ports 411. Under the action of gravity, the concentrated Chinese medicine liquid is gathered at the bottom in the evaporation tank 11. Meanwhile, the rotating spiral blades 43 can continuously lift the concentrated Chinese medicine liquid inside the cylinder 41 upwards, achieving the effect of "central lifting" of the concentrated Chinese medicine liquid inside the cylinder 41. The concentrated Chinese medicine liquid rising upward inside the cylinder 41 is blocked by the annular baffle 44 and will flow into the two rectangular tubes 32. Since the two rectangular tubes 32 rotate synchronously with the cylinder 41, the concentrated Chinese medicine liquid entering the rectangular tubes 32 is thrown outward under the centrifugal force generated by the rotation of the rectangular tubes 32, realizing the effect of "centrifugal ejection from the top" of the concentrated Chinese medicine liquid in the evaporation tank 11. The concentrated Chinese medicine liquid is thrown onto the inner wall of the evaporation tank 11, and then falls down along the inner wall of the evaporation tank 11 under the action of gravity, realizing the effect of "gravity reflux of the wall" of the concentrated Chinese medicine liquid in the evaporation tank 11.

[0042] Furthermore, the "traditional Chinese medicine concentrate" at different liquid levels inside the evaporation tank 11 exhibits varying degrees of heating and evaporation rates, resulting in a significant concentration gradient between the upper and lower layers within the evaporation tank 11. This concentration difference leads to uneven distribution of the effective components in the final concentrate. Through the cooperation of the lifting mechanism 4 and the two rectangular tubes 32, the traditional Chinese medicine concentrate that was originally located at the bottom of the evaporation tank 11 can be conveyed upwards and then thrown towards the inner wall of the evaporation tank 11, allowing the traditional Chinese medicine concentrate to flow down the inner wall of the evaporation tank 11 again. This ensures that the traditional Chinese medicine concentrate can maintain sufficient and effective contact with the inner wall of the evaporation tank 11 even as the liquid level decreases, avoiding the waste of heat energy in the evaporation tank 11 due to the decrease in liquid level, and resulting in significant economic benefits.

[0043] Furthermore, such as Figures 2-9 As shown, two vortex-shaped scrapers 31 gather the concentrated Chinese medicine liquid in the evaporation tank 11 towards the center, and the lifting mechanism 4 conveys the concentrated Chinese medicine liquid at the bottom of the evaporation tank 11 upwards. Finally, two rectangular tubes 32 throw the concentrated Chinese medicine liquid conveyed upwards by the lifting mechanism 4 onto the inner wall of the evaporation tank 11, so that the concentrated Chinese medicine liquid can be fully mixed during the concentration process in the evaporation tank 11, effectively breaking the temperature gradient and concentration gradient, ensuring that the concentration of effective components of the concentrated Chinese medicine liquid is highly uniformly distributed in the evaporation tank 11, realizing a specific closed loop path of "bottom gathering → center lifting → upper centrifugal throwing → wall gravity return", achieving efficient mixing and anti-wall adhesion effects.

[0044] like Figures 5-6 As shown, both rectangular tubes 32 are inclined, and the end of the rectangular tube 32 closer to the cylinder 41 is higher than the other end.

[0045] Furthermore, the end of the rectangular tube 32 closest to the cylinder 41 is higher than the other end, which can ensure that the concentrated Chinese medicine liquid inside the rectangular tube 32 can also slide along the inclined bottom inner wall of the rectangular tube 32 under its own gravity to the outlet 321 and be discharged through the outlet 321.

[0046] In this embodiment: the concentrated Chinese medicine liquid is injected into the inner evaporation tank 11 through the feed pipe 17, and then circulating steam is injected into the outer evaporation tank 12. The steam can heat the concentrated Chinese medicine liquid in the inner evaporation tank 11. After the concentrated Chinese medicine liquid is heated, the solvent in it evaporates and vaporizes, and is discharged through the discharge pipe 15 and enters the separator 21 through the conduit 22. The separator 21 can separate the droplets / bubbles in the vaporized solvent. Then the vaporized solvent enters the condenser 25 through the conduit 26 for cooling and re-liquefaction into liquid. The liquefied solvent in the condenser 25 will fall into the collection tank 27 and be collected.

[0047] The rotation of motor 110 will drive shaft 42 to rotate, shaft 42 will drive spiral blade 43 to rotate, shaft 42 will also drive internal gear ring 54 to rotate, internal gear ring 54 will drive external gear ring 53 to rotate through multiple gears 52, external gear ring 53 will then drive cylinder 41 to rotate, and cylinder 41 will drive two vortex scrapers 31 to rotate synchronously.

[0048] When the cylinder 41 rotates clockwise, the ends of the two vortex-shaped scrapers 31 away from the center will rotate against the inner wall of the evaporation tank 11. During this process, the two vortex-shaped scrapers 31 can scrape off the concentrated Chinese medicine liquid attached to the inner wall of the evaporation tank 11, and the scraped-off concentrated Chinese medicine liquid will fall under the action of gravity.

[0049] During the clockwise rotation of the two vortex scrapers 31, the concentrated Chinese medicine liquid that was originally close to the inner wall of the evaporation tank 11 can be continuously gathered towards the cylinder 41. The concentrated Chinese medicine liquid gathered near the cylinder 41 will enter the inside of the cylinder 41 through multiple feed ports 411, while the rotating spiral blades 43 can continuously lift the concentrated Chinese medicine liquid inside the cylinder 41 upwards.

[0050] The upward-moving concentrated Chinese medicine liquid inside the cylinder 41 is blocked by the annular baffle 44, changing its flow direction and flowing into the two rectangular tubes 32 respectively. As the two rectangular tubes 32 rotate, the concentrated Chinese medicine liquid entering the rectangular tubes 32 is thrown outward under the centrifugal force generated by the rotation of the rectangular tubes 32, and is evenly splashed and coated on the upper inner wall of the evaporation tank 11. After being thrown onto the inner wall of the evaporation tank 11, the concentrated Chinese medicine liquid will fall down along the inner wall of the evaporation tank 11 under the action of gravity.

[0051] The medicinal liquid coated on the inner wall of the evaporation tank 11 flows downward along the inner wall under the action of gravity. During this process, it comes into full contact with the heated wall surface and is evaporated and concentrated. At the same time, the medicinal liquid at the bottom is continuously lifted, thrown out, and refluxed, forming a powerful forced circulation, which completely breaks the temperature and concentration stratification and realizes the homogenization of the medicinal liquid in the tank.

[0052] In the above process, under the action of two vortex-shaped scrapers 31, cylinder 41, spiral blades 43, and two rectangular tubes 32, the flow direction of the concentrated Chinese medicine liquid in the evaporation tank 11 is as follows: Figure 9 As shown, a specific closed-loop path of "bottom gathering → center lifting → upper centrifugal ejection → wall gravity reflux" is achieved, realizing efficient mixing and anti-wall adhesion effects. Finally, the concentrated "Chinese medicine concentrate" can be discharged through discharge valve 19.

[0053] This application utilizes the spiral guidance of two vortex-shaped scrapers 31 to achieve a sequential control where "materials that first contact the inner wall of the evaporation tank 11 enter the circulation first." Materials that first contact the inner wall of the evaporation tank 11 and have a longer heating time are preferentially pushed to the inlet 411 at the bottom of the central cylinder 41, and then preferentially enter the closed-loop path of "central lifting → upper centrifugal ejection → gravity reflux from the wall," thus actively detaching from the heating zone to avoid localized overheating. Materials that contact the tank wall later and have a shorter heating time then enter the circulation, receiving sufficient heating. This differentiated and sequential aggregation based on the spatial position of the materials ensures that the cumulative contact time between each part of the material and the heating wall within a unit of time tends to be consistent, achieving equalization of the material's heating time and ultimately guaranteeing the uniformity of the concentration of the effective components in the concentrate and the stability of batch-to-batch quality.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
