Background Art

[0002] Chinese medicine refers to medicines that are used for the treatment, diagnosis and prevention of diseases under the guidance of traditional Chinese medicine theory, and have health care and rehabilitation effects. They mainly include Chinese medicinal materials, Chinese medicine slices and Chinese patent medicines. Chinese medicine mainly comes from natural plants, animals, minerals and their processed products. Most of them are plants, such as Bupleurum, Rehmannia, Coptis, Lily, Ginseng, and Ganoderma. Animal Chinese medicines include deer antlers, tortoise shells, earthworms, scorpions, centipedes, etc. Mineral Chinese medicines include cinnabar, natural copper, Glauber's salt, realgar, gypsum, talc, etc. With the development of the economy and society and the development of the Chinese medicine industry, people pay more and more attention to the role of Chinese medicine in regulating the body. Therefore, the demand for Chinese medicine is also increasing. Chinese medicine extraction and concentration technology is a very important process in the Chinese medicine process. Extraction and concentration, as an important process in the Chinese medicine process, directly affect the quality of the medicine.

[0003] Chinese patent CN116688535A discloses a Chinese medicine effective component extraction and concentration device and its use method, including a tank body, a heater is installed at the bottom of the inner surface of the tank body, a stirring assembly has an elastic strip fixed at the bottom of the inner surface of the tank body and close to the heater, the top of the elastic strip is fixedly connected with an active sheet, the outer surface of the active sheet is fixedly connected with a secondary sheet, the top of the active sheet is fixedly connected with a top cap, the top of the outer surface of the top cap is fixedly connected with a crescent block, the inner center of the barrel is rotatably connected with a driving roller through a bracket, the outer surface of the driving roller is fixedly connected with a rotating tooth, the inner surface of the barrel is fixedly connected with a base tooth, and the bottom of the driving roller is installed with a steam processor. The Chinese medicine effective component extraction and concentration device and its use method achieve the effect of rapid extraction and concentration, can make the raw materials evenly heated, and timely process the steam to reduce the dripping of water droplets, which is helpful for the extraction and concentration of Chinese medicine.

[0004] The above-mentioned device extracts the medicine by heating the internal medicine liquid of the tank body, and collects the steam generated during the extraction through a steam processor. Although the steam water in the flowing steam can be collected by the steam processor, the steam will pre-contact the inner wall of the stirring component and the tank disc screen during the rising process, resulting in condensation water on the stirring component and the tank disc screen, and this condensation water will directly fall back into the medicine liquid inside the tank body and affect the extraction effect. At the same time, the device directly mixes the liquid with the herbal medicine each time it extracts the medicine liquid, which makes the subsequent processing troublesome and inconvenient to clean the tank body.

[0015] An extraction process of a Chinese herbal medicine extract concentration device that prevents liquefied water droplets from dripping, comprising the following steps:

[0016] S1. The crushed Chinese herbal medicine is conveyed to the herbal medicine separation and extraction device installed at the bottom of the heating extraction tank by rotating the feed shaft, and a proper amount of extracting liquid is added into the heating extraction tank until the preset liquid level is reached. At this time, the first liquid level detector inside the heating extraction tank monitors and feeds back the liquid level information in real time;

[0017] S2, start the rotary drive device, so that the rotating feed shaft starts to rotate, and at the same time drives the medicinal material separation extraction device and the rotating guide top to rotate synchronously, and the heating extraction tank starts to heat the internal extract to promote the dissolution and extraction of the effective ingredients;

[0018] S3. As the medicinal material separation and extraction device rotates and rises, the Chinese herbal medicine and the extract are in limited flow contact. During the heating process, the water in the extract evaporates to form steam, which rises and passes through the rotating guide top. The rotating guide top performs preliminary separation on the rising steam, collects part of the steam water, and reduces the droplets carried in the steam.

[0019] S4. The water droplet collecting device intelligently adjusts the working end position of the water droplet collecting device according to the information of the first liquid level detector to avoid direct contact with the extract. During the rotation of the rotating guide top, the water droplets condensed on the surface are thrown around and flow to the inner wall. The working end of the water droplet collecting device performs periodic lifting and lowering motions to scrape off the water droplets on the surface of the rotating feed shaft and the heated extraction tank to prevent them from dripping back into the extract;

[0020] S5, the steam continues to flow to the water-gas heat recovery component for secondary separation and heat recovery;

[0021] S6. After the active ingredients in the extract are fully extracted, the medicinal residue is quickly separated using a medicinal material separation extractor to simplify the cleaning process.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This device innovatively designs a water droplet collection device, which combines the rotating guide top inside the heating extraction tank and the rotating feed shaft to effectively prevent the condensed water droplets formed by the steam contacting the internal components of the tank during the rising process from directly dripping back into the extract. By intelligently adjusting the position of the working end of the water droplet collection device and scraping off the water droplets in combination with periodic lifting and lowering movements, the purity of the extraction process is ensured, and the contamination of the extract by water droplets is avoided, thereby ensuring the quality and purity of the Chinese herbal medicine extract;

[0024] 2. The application of the herbal medicine separation and extraction device realizes the limited mixing of Chinese herbal medicine and the extract, which not only promotes the full dissolution and extraction of the effective ingredients, but also avoids the post-processing difficulties caused by the direct mixing of Chinese herbal medicine and the extract in the traditional method. This design not only improves the extraction efficiency, but also makes the extraction process more orderly and controllable, which is convenient for the subsequent separation of the drug residue and the cleaning of the heating tank;

[0025] 3. This device integrates heating extraction, medicinal material separation, steam treatment, water droplet collection and heat recovery into a compact and efficient extraction system. This integrated design not only simplifies the equipment structure and reduces the floor space, but also improves the overall performance and stability of the equipment. In addition, by intelligently controlling the working status of each functional module, it can be flexibly adjusted according to different extraction needs to meet the extraction requirements of different types of Chinese herbal medicines, thereby enhancing the adaptability and flexibility of the equipment.

[0026] 4. The diversion extractor in the device is provided with an inclined diversion track, a diffusion drainage hole, a filter sleeve and a stirring rack. At the same time, the diversion extractor can rotate and rise and fall. During the rotation and rise and fall process, the extract can more fully penetrate into the Chinese herbal medicine, accelerating the dissolution of the effective components. Under the guidance of the diversion track, the extract passes through the filter sleeve and carries the effective components in the Chinese herbal medicine, and then is distributed to the heating extraction tank area through the diffusion drainage hole. Due to the rotation and rise and fall of the diversion extractor, the extract carrying the effective components of the Chinese herbal medicine can be evenly distributed around and above the heating extraction tank, thereby avoiding the high concentration of the effective components of the Chinese herbal medicine around the diversion extractor, which affects the extraction of the effective components of the Chinese herbal medicine. In addition, due to the rise and fall of the diversion extractor, the Chinese herbal medicine in the diversion extractor is squeezed, which can accelerate the release and circulation of the effective components of the Chinese herbal medicine. That is, by combining the inclined diversion track, diffusion drainage hole, filter sleeve and stirring rack together, and coordinating the rotation and rise and fall of the diversion extractor, the extraction efficiency can be further improved.

DETAILED DESCRIPTION

[0040] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0041] See also Figures 1 to 12 As shown, a Chinese herbal medicine extract concentration device that prevents liquefied water droplets from dripping comprises a heating extraction tank 1, a rotating feed shaft 2, a medicinal material separation extraction tool 3, a rotating guide top 4, a water droplet collection device 5 and a water vapor heat energy recovery component 6; a first liquid level detector is provided inside the heating extraction tank 1, and the first liquid level detector is used to detect the liquid level; the rotating feed shaft 2 is installed at the axial position of the heating extraction tank 1; the medicinal material separation extraction tool 3 is installed at the bottom of the heating extraction tank 1, and the medicinal material separation extraction tool 3 is transmission-connected to the rotating feed shaft 2; the rotating guide top 4 is installed at the top of the heating extraction tank 1, and the rotating guide top 4 is rotationally connected to the heating extraction tank 1, and the rotating guide top 4 is transmission-connected to the rotating feed shaft 2; the water droplet collection device 5 is installed on the heating extraction tank 1, and the working end of the water droplet collection device 5 is arranged inside the heating extraction tank 1; the water vapor heat energy recovery component 6 is installed on the outside of the heating extraction tank 1, and the water vapor heat energy recovery component 6 is connected to the rotating guide top 4.

[0042] The staff first transports the crushed Chinese herbal medicine to the medicinal material separation extractor 3 installed at the bottom of the heated extraction tank 1 through the rotating feed shaft 2. The design of the medicinal material separation extractor 3 ensures that the Chinese herbal medicine and the extract are mixed in a limited position, which is convenient for subsequent processing and cleaning. Subsequently, an appropriate amount of extract is added to the heated extraction tank 1 through a preset inlet until the preset liquid level is reached. The first liquid level detector inside the heated extraction tank 1 monitors and feeds back the liquid level information in real time. Start the rotary drive device 23 to drive the rotating feed shaft 2 to start rotating. The rotation of the rotating feed shaft 2 also drives the medicinal material separation extractor 3 and the rotating guide top 4 to rotate synchronously. As the medicinal material separation extractor 3 rotates, the Chinese herbal medicine inside it achieves rapid and effective limited flow contact with the extract, promoting the dissolution and extraction of the active ingredients. This design avoids the drawbacks of direct mixing of Chinese herbal medicine and extract in traditional methods, improves the extraction efficiency and simplifies the subsequent processing flow. The heated extraction tank 1 heats the internal extract to cause the water in the extract to evaporate and form steam. The steam then rises, passes through the rotating guide top 4 and flows to the water vapor heat energy recovery component 6. The rotating guide top 4 performs preliminary separation on the rising steam and collects part of the steam water. Subsequently, the uncondensed steam enters the water vapor heat energy recovery component 6 for secondary separation and heat energy recovery, thereby maximizing the utilization of resources.

[0043] During the rising process, the steam will contact the rotating guide top 4, the rotating feed shaft 2 and the inner wall of the heated extraction tank 1 to form condensed water droplets. If these water droplets are not handled in time, they will drip back into the extract and affect the extraction effect. The water droplet collecting device 5 intelligently adjusts the position of its working end according to the information provided by the first liquid level detector inside the heated extraction tank 1 to avoid direct contact with the extract. As the rotating guide top 4 rotates, the condensed water droplets are thrown around and flow to the inner wall of the heated extraction tank 1. At this time, the working end of the water droplet collecting device 5 performs periodic lifting and lowering motions to scrape the surface of the rotating feed shaft 2 and the heated extraction tank 1, effectively removing the condensed water droplets and preventing them from dripping back into the extract. After a period of extraction, the heating and rotation are stopped according to the preset conditions, and the effective ingredients in the extract are fully extracted. Due to the design of the medicinal material separation extractor 3, the medicinal residue can be quickly separated after the extraction is completed, simplifying the cleaning process. The rotating drive device 23 is a prior art and will not be described here.

[0044] See also Figures 1 to 4 As shown, a feed channel 21 is provided at the axial position of the rotating feed shaft 2, a guide hopper 22 is installed on the top of the rotating feed shaft 2, a limit shrinkage rail 25 is provided at the bottom of the rotating feed shaft 2, the limit shrinkage rail 25 is limit-connected to the top of the medicinal material separation and extraction device 3, and a limit pressing device 24 is also installed inside the feed channel 21.

[0045] The limiting and shrinking rail 25 is used to cooperate with the installation of the medicinal material separation and extraction device 3.

[0046] A feed channel 21 is provided at the axis position of the rotating feed shaft 2, and a guide hopper 22 is installed on the top. The staff pours the crushed Chinese herbal medicine into the feed channel 21 through the guide hopper 22, and the Chinese herbal medicine then slides down the channel to the bottom. A limited pressing device 24 is also installed inside the feed channel 21, which compacts the Chinese herbal medicine to a certain extent during its sliding process to ensure that it is evenly distributed in the medicinal material separation and extraction device 3, thereby improving the extraction efficiency. At the same time, the limited pressing device 24 can also prevent the Chinese herbal medicine from blocking the feed channel 21, ensuring smooth feeding.

[0047] See also Figures 4 to 6As shown, the limit pressing device 24 includes an adjusting screw 241 installed inside the rotating feed shaft 2, a rotating docking joint 2411 is provided on the top of the adjusting screw 241, a pressing plate 242 is also installed on the adjusting screw 241, the adjusting screw 241 is threadedly connected with the pressing plate 242, the pressing plate 242 is limitedly slidably connected with the feed channel 21, the limit pressing device 24 also includes a docking drive device 243 for driving the adjusting screw 241 to rotate, the docking drive device 243 includes a mounting bracket 2431, a movable bracket 2432 is installed on the mounting bracket 2431, a reset spring 2434 is installed between the movable bracket 2432 and the mounting bracket 2431, a rotating driver 2435 is installed on the movable bracket 2432, a transmission docking joint 2436 is installed on the output end of the rotating driver 2435, and the transmission docking joint 2436 is arranged directly above the rotating docking joint 2411.

[0048] When it is necessary to start feeding, the staff will continue to press the movable bracket 2432 to dock the transmission docking joint 2436 with the rotating docking joint 2411, and then the rotary driver 2435 will start. As the rotary driver 2435 rotates, the transmission docking joint 2436 drives the rotating docking joint 2411 and the adjusting screw 241 to rotate synchronously. The rotation of the adjusting screw 241 causes the pressing plate 242 to move up and down in the feeding channel 21. When it is necessary to place Chinese herbal medicines, the pressing plate 242 rises to the top of the guide hopper 22 through the adjusting screw 241, and the Chinese herbal medicines enter the feeding channel 21 through the guide hopper 22 and slide down into the medicinal material separation and extraction device 3. After the Chinese herbal medicines are placed, the pressing plate 242 is driven down by the adjusting screw 241 to compact the herbs to a certain extent to ensure that they are evenly distributed in the medicinal material separation and extraction device 3. The compaction process also reduces the gaps between the herbs and improves the extraction efficiency. The pressing plate 242 in the limit pressing device 24 can also prevent the herbs from blocking the feed channel 21. When encountering larger herb clumps or foreign objects, the pressing plate 242 helps them pass through the feed channel 21 smoothly by increasing the pressing force, thus avoiding the occurrence of blockage. After completing one compaction, the rotary driver 2435 stops working, and the staff also stops pressing the movable bracket 2432. The return spring 2434 pushes the movable bracket 2432 and the rotary driver 2435 back to the initial position. At this time, the transmission docking joint 2436 is separated from the rotating docking joint 2411. The limit pressing device 24 realizes uniform compaction and smooth feeding of Chinese herbal medicines.

[0049] See also Figure 5 , Figure 7 , Figure 8 and Fig.11As shown, the medicinal material separation extractor 3 includes a lifting guide sleeve 34 installed at the bottom of the heating extraction tank 1, the inner wall of the lifting guide sleeve 34 is provided with an inclined circulation groove 341, and a lifting and pressing seat 35 is installed inside the lifting guide sleeve 34. The inner wall of the lifting and pressing seat 35 is provided with a sliding ball 351, and the sliding ball 351 is slidably connected with the inclined circulation groove 341. A material removal valve 33 is installed at the axial position of the lifting and pressing seat 35, and a diversion extractor 31 is also installed on the lifting and pressing seat 35. The top of the diversion extractor 31 is connected to the limiting contraction rail 25 of the rotating feed shaft 2, and a detachable filter sleeve 32 is installed inside the diversion extractor 31. The staff first transports the crushed Chinese herbal medicine to the diversion extractor 31 through the rotating feed shaft 2. Since the rotating feed shaft 2 is connected to the top of the diversion extractor 31, the Chinese herbal medicine can smoothly enter the filter sleeve 32. When an appropriate amount of extract is added to the heating extraction tank 1 through a preset inlet and reaches a preset liquid level, the heating extraction tank 1 starts to heat the extract. As the rotating feed shaft 2 rotates, the diversion extractor 31, the filter sleeve 32 and the lifting and pressing seat 35 rotate synchronously. This rotational action promotes the uniform distribution of the extract in the filter sleeve 32 and allows the extract to penetrate into the Chinese herbal medicine. When the lifting and pressing seat 35 rotates, the sliding ball 351 moves along the inclined circulation groove 341 of the lifting guide sleeve 34. The inclined circulation groove 341 guides the sliding ball 351 to move, which causes the lifting and pressing seat 35 to move up and down. When the lifting and pressing seat 35 moves up and down, it will drive the diversion extractor 31 and the filter sleeve 32 to move synchronously. The top of the diversion extractor 31 will telescope into the limit contraction rail 25 of the rotating feed shaft 2. The lifting and pressing seat 35 will drive the diversion extractor 31 to move upward and downward. The Chinese herbal medicines in the tool are raised and lowered, squeezing the Chinese herbal medicines and the extract inside at the same time. The squeezing of the Chinese herbal medicines and the extract will accelerate the speed at which the extract flows and contacts the Chinese herbal medicines. At the same time, the squeezing of the Chinese herbal medicines will better release their medicinal properties. The extract from which the effective ingredients of the Chinese herbal medicines are extracted enters the heating extraction tank 1 through the diffusion drainage holes 312 at different heights as the diversion extraction tool 31 is raised and lowered, so that the extract carrying the effective ingredients of the Chinese herbal medicines can be evenly distributed around and above and below the heating extraction tank 1, thereby avoiding the high concentration of the effective ingredients of the Chinese herbal medicines around the diversion extraction tool 31, which affects the extraction of the effective ingredients of the Chinese herbal medicines, and effectively improves the extraction effect.

[0050] The diversion extractor 31 and the filter sleeve 32 cooperate to achieve limited flow contact extraction between Chinese herbal medicine and the extract. Since the Chinese herbal medicine is limited inside the filter sleeve 32, the extraction process is more efficient and easy to control. Under the action of heating and rotation, the active ingredients in the Chinese herbal medicine gradually dissolve in the extract and penetrate to the outside through the filter sleeve 32. This process avoids the problems of impurities and reduced extraction efficiency that may be caused by direct mixing of Chinese herbal medicine and extract in traditional methods. After the extraction is completed, turn off the heating and rotation device, and quickly discharge the residue in the diversion extractor 31 by opening the discharge valve 33. Due to the detachability of the filter sleeve 32, the cleaning process is simpler and faster. At the same time, since the Chinese herbal medicine and the extract are always in a limited state during the extraction process, the impurity content of the Chinese herbal medicine in the extract is low, further simplifying the subsequent processing flow of the extract.

[0051] See also Figure 7 and Figure 8 As shown, a limit slider 314 is provided on the top of the diversion extractor 31, and the limit slider 314 is slidably connected to the limit contraction rail 25 of the rotating feed shaft 2. A plurality of inclined diversion rails 311 are provided on the outer wall of the diversion extractor 31, and a plurality of diffusion drainage holes 312 are provided below the inclined diversion rails 311. A stirring frame 313 is also installed on the outer side of the diversion extractor 31.

[0052] The top of the diversion extractor 31 is provided with a limiting slider 314 for limited installation in cooperation with the limiting shrinkage track 25 of the rotating feed shaft 2, so that the diversion extractor 31 can rotate synchronously with the rotating feed shaft 2, and the diversion extractor 31 can also move up and down in the limiting shrinkage track 25 when rotating. When the diversion extractor 31 rotates and moves up and down, the inclined diversion track 311 rotates with the diversion extractor 31, and the inclined track will guide the extract to flow quickly along the set path to the inside of the diversion extractor 31, ensuring that the extract can be evenly and efficiently covered on the surface of the Chinese herbal medicine, thereby improving the extraction efficiency. The guiding effect of the inclined diversion track 311 also promotes the mixing of the extract and the Chinese herbal medicine, so that the extract can more fully penetrate into the inside of the Chinese herbal medicine, accelerating the dissolution of the effective ingredients. The multiple diffusion drainage holes 312 located below the inclined diversion track 311 are used to receive and diffuse the extract flowing out from the inside of the diversion extractor 31. When the extract is guided by the guide track, it will pass through the filter sleeve 32 and carry the effective ingredients in the Chinese herbal medicine. These liquids are evenly distributed to the bottom area of ​​the heated extraction tank 1 through the diffusion drainage hole 312. This diffusion drainage method helps to reduce the problem of local excessive concentration or uneven extraction, and improve the overall extraction effect. The design of the diffusion drainage hole 312 can also effectively prevent the extract from accumulating at the bottom of the guide extractor 31, avoiding uneven heat distribution or decreased extraction efficiency due to accumulation. The stirring frame 313 installed on the outside of the guide extractor 31 will continuously lift, rotate, stir and heat the extract at the bottom of the extraction tank 1 during the rotation and lifting movement of the guide extractor 31. The lifting, rotating and stirring action not only further promotes the mixing of the extract and the Chinese herbal medicine, but also improves the uniformity and temperature distribution of the extract, which helps to accelerate the dissolution and diffusion of the effective ingredients.

[0053] See also Figures 3 to 5 As shown, the rotating guide top 4 includes a fixed guide cover 41 installed on the top of the heating and extraction tank 1, and the outer side of the fixed guide cover 41 is provided with an air outlet 411 and a liquid discharge port 412. The rotating guide top 4 also includes a rotating double-layer guide top arranged inside the fixed guide cover 41, and the rotating double-layer guide top is connected to the rotating feed shaft 2. The rotating double-layer guide top is composed of a guide top 42 and a condensation top 43. An air flow channel 431 is provided between the guide top 42 and the condensation top 43. A flow hole is provided at the axial position of the guide top 42, and the flow hole is connected to the air flow channel 431. A plurality of annular water-gas contact sheets 432 are provided inside the air flow channel 431.

[0054] When the extract in the heating extraction tank 1 is heated to boiling and steam is generated, the steam will rise and first contact the rotating guide top 42. The guide top 42 is provided with flow holes at the axial position, and these flow holes are connected to the air flow channel 431, so that the steam can smoothly enter the air flow channel 431. In the air flow channel 431, multiple annular water vapor contact sheets 432 make preliminary contact and condense the rising steam, so that part of the steam condenses into water droplets, while the remaining steam continues to flow outward. The water droplets condensed on the annular water vapor contact sheet 432 will flow down along the inner wall of the air flow channel 431, and finally be discharged through the drain port 412, avoiding the water droplets from dripping back into the extract. The design of the drain port 412 ensures that the water droplets can be discharged smoothly and prevents steam leakage. The steam that has been preliminarily treated is discharged through the outlet 411 on the outside of the fixed guide cover 41, and enters the water vapor heat energy recovery component 6 for further processing and heat energy recovery. The effective discharge of steam is achieved, and the heat energy in the steam is fully utilized, thereby improving the energy utilization efficiency.

[0055] See also Figure 4 , Figure 5 and Fig. 9 As shown, the water droplet collecting device 5 includes a condensate collecting tool 51 installed inside the heating and extraction tank 1, and a first collecting ring 511 and a second collecting ring 512 are provided on the condensate collecting tool 51. The first collecting ring 511 and the second collecting ring 512 are connected to each other, and a water collecting trough 513 is provided inside the first collecting ring 511 and the second collecting ring 512. The outer ring of the first collecting ring 511 is in contact with the inner wall of the heating and extraction tank 1, and the inner ring of the second collecting ring 512 is connected to the rotating feed shaft 2. A second liquid level detector 52 is also provided inside the water collecting trough 513. The water droplet collecting device 5 also includes a lifting and adjusting device 54. The lifting end of the lifting and adjusting device 54 passes through the rotating guide top 4 and is connected to the condensate collecting tool 51. A suction pipe 53 is also installed on the lifting and adjusting device 54, and the suction pipe 53 is used to suck the liquid inside the water collecting trough 513.

[0056] During the heating and extraction process, the steam contacts the rotating guide top 4, the rotating feed shaft 2 and the inner wall of the heating and extraction tank 1 during the rising process, forming condensed water droplets. These water droplets are collected by the first collection ring 511 and the second collection ring 512 respectively, and flow into the water collection tank 513. The control system starts the lifting and adjusting device 54. The lifting and adjusting device 54 performs lifting and lowering movement according to the control signal, driving the condensed water collection device 51 to move up and down. During the lifting and lowering process, the position of the condensed water collection device 51 is adjusted. The second liquid level detector 52 monitors the liquid level in the water collection tank 513 in real time. When the liquid level in the water collection tank 513 reaches the preset threshold, the suction pipe 53 starts to work, extracts the liquid in the water collection tank 513 and discharges it to the designated position to prevent the water droplets from flowing back into the extract. The entire collection process is a periodic operation, which is automatically adjusted according to the actual situation and preset conditions in the heating and extraction tank 1. The working state of the lifting and adjusting device 54 and the suction pipe 53 is intelligently controlled by the control system to ensure the efficiency and accuracy of water droplet collection.

[0057] The water droplet collecting device 5 realizes the effective collection and treatment of the condensed water droplets generated during the heating extraction process, thereby ensuring the purity of the extract and the extraction effect.

[0058] See also Figure 5 , Fig. 9 and Fig.12 As shown, the lifting and adjusting device 54 includes a lifting screw slide 541 installed on the outside of the heating and extraction tank 1, and a synchronous connecting ring 542 is installed on the movable end of the lifting screw slide 541. A plurality of connecting rods 543 are installed on the synchronous connecting ring 542. The connecting rod 543 passes through the rotating guide top 4 and is fixedly connected to the condensate collecting device 51. A suction hole 5431 is provided at the axial position of the connecting rod 543, and the suction hole 5431 is connected to the water collecting tank 513.

[0059] When the lifting screw slide 541 is started, the lifting screw slide 541 drives the synchronous connecting ring 542 to move up and down, and drives the condensate collector 51 to move up and down through the synchronous connecting ring 542 and the connecting rod 543. This process not only helps to adjust the position of the collector to adapt to condensate drops at different heights, but also promotes the gathering and discharge of the drops to a certain extent.

[0060] When the liquid level in the water collection tank 513 reaches a preset threshold, the second liquid level detector 52 sends a signal to the control system, triggering the suction pipe 53 to start working. The suction pipe 53 is connected to the water collection tank 513 through the suction hole 5431 at the axis of the connecting rod 543, and uses the negative pressure principle to extract the liquid in the water collection tank 513 and discharge it to a designated location. This process effectively prevents water droplets from flowing back into the extract, ensuring the purity of the extract.

[0061] See also Figure 1 , Figure 4 and Fig.10 As shown, the water vapor heat energy recovery component 6 includes an annular baffle tube 61 installed on the outer wall of the heating and extraction tank 1, the air inlet end of the annular baffle tube 61 is connected to the air outlet 411 of the fixed guide cover 41, and an annular drain pipe 62 is provided below the annular baffle tube 61, and a plurality of bent drain pipes 63 are installed between the annular drain pipe 62 and the annular baffle tube 61.

[0062] When the extract in the heating extraction tank 1 boils and generates steam, the steam first contacts the rotating guide top 42. After preliminary condensation, the uncondensed steam enters the annular baffle tube 61 through the air outlet 411 on the outside of the fixed guide cover 41. When the steam flows in the annular baffle tube 61, heat exchange occurs with the tube wall, and the released heat energy is transferred to the outer wall of the heating extraction tank 1, thereby realizing the recovery and utilization of heat energy. As the steam flows and cools continuously in the annular baffle tube 61, part of the steam will condense into water droplets attached to the tube wall. These water droplets flow down along the tube wall under the action of gravity, and are guided by the bent drain pipe 63 and finally collected in the annular drain pipe 62. The condensed water collected in the annular drain pipe 62 is discharged to the designated location through the pipeline system, realizing the effective collection and discharge of the condensed water. The entire water vapor heat energy recovery process is a continuous cycle process. As the steam in the heating extraction tank 1 is continuously generated and discharged, the steam in the annular baffle tube 61 is also continuously flowing and exchanging heat, ensuring the continuity and efficiency of heat energy recovery. The effective recovery and utilization of steam heat energy not only improves energy utilization efficiency, but also reduces heat energy waste and environmental pollution.
