Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicine preparation, and in particular to a method for preparing a Chinese medicine preparation for strengthening the spleen and activating blood circulation and a preparation device thereof. Background Art

[0002] In the field of Chinese medicine preparation, spleen-strengthening and blood-activating Chinese medicines have attracted much attention due to their unique efficacy and wide application prospects. However, the traditional preparation methods of Chinese medicine preparations have many shortcomings, such as cumbersome preparation processes, separate equipment, complex operations, and low efficiency, which seriously restrict the industrial production and modernization of Chinese medicine preparations.

[0003] Specifically, the traditional preparation process of Chinese medicine preparations usually requires multiple steps such as cleaning, crushing, extraction and concentration of medicinal materials, and these steps often need to be carried out in different equipment, resulting in a cumbersome and inefficient preparation process. At the same time, due to the separation of equipment, medicinal materials need to be frequently transferred during operation, which increases the risk of manual intervention and contamination, and affects the consistency and stability of the preparation process. In addition, traditional equipment also has shortcomings in the crushing and screening of medicinal materials, such as poor crushing effect and incomplete screening, resulting in poor fineness and uniformity of medicinal material powder, affecting the quality and efficacy of Chinese medicine preparations.

[0004] Therefore, in order to solve the above problems, the present invention provides a method for preparing a Chinese medicine preparation for strengthening the spleen and promoting blood circulation and a preparation device thereof. Summary of the invention

[0005] To solve the above problems, the present invention provides a method for preparing a Chinese medicine preparation for strengthening the spleen and activating blood circulation and a preparation device thereof, aiming to realize the automation and continuity of the preparation process, improve the crushing and screening effects of medicinal materials, and thus ensure the quality and efficacy of the Chinese medicine preparation.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: a preparation device of a Chinese medicine preparation for strengthening the spleen and activating blood circulation, comprising a shell, wherein a cleaning chamber, a crushing chamber, an extraction chamber and a concentration chamber are arranged in sequence from top to bottom inside the shell, and all the chambers are connected in sequence, and a crushing assembly for crushing medicinal materials is installed in the crushing chamber, and the crushing assembly comprises a mounting frame and a first power member, and a first slide groove and a second slide groove are provided on the mounting frame, and a reset assembly for resetting the first power member is installed in the first slide groove, and the reset assembly is installed on the side walls on both sides of the first power member, and the output shaft of the first power member is coaxially fixedly connected with a roller, and the outer wall of the roller and the inner wall of the crushing chamber are gap-matched;

[0007] The end of the drum away from the first power member is eccentrically connected to a connecting rod, the end of the connecting rod away from the drum is rotatably matched with a sliding block, the sliding block is slidably matched with the second slide groove, reset components are installed on both sides of the sliding block, the sliding block and the bottom wall of the first power member are installed with vertical rods, and one end of the vertical rod away from the sliding block and the first power member is respectively fixedly connected with a screening component for screening and secondary grinding of medicinal material powder, a heating component is installed inside the drum and the screening component, the heating component signal is connected to a control component, the control component is connected to the first power member signal, and the control component is used to control the opening and closing of the heating component and the first power member.

[0008] The technical principle of the above scheme is as follows: The preparation device of the present invention realizes a complete preparation process from cleaning to extraction and concentration of medicinal materials through the setting of multiple functional areas. Among them, the crushing chamber is the key part, and the medicinal materials are crushed by the crushing assembly to facilitate subsequent extraction and concentration. The crushing assembly is composed of a mounting frame, a first power member, a drum, a connecting rod, a sliding block, a vertical rod, etc. The first power member drives the drum to rotate, and the outer wall of the drum and the inner wall of the crushing chamber are gap-matched to ensure that the medicinal materials are crushed under the rotation of the drum. At the same time, the setting of the connecting rod and the sliding block causes the drum to produce a certain amount of swing or vibration during the rotation process, which is conducive to the uniform crushing of the medicinal materials.

[0009] The screening component is used to screen and re-grind the medicinal material powder to ensure that the powder particle size meets the requirements. The heating component is installed inside the drum and screening component. Through the control of the control component, the medicinal material can be heated during the crushing and screening process, which helps to release the active ingredients in the medicinal material.

[0010] The above scheme has the following beneficial effects:

[0011] 1. Compared with the shortcomings of traditional devices with multiple separate devices and cumbersome operations, the device of the present invention cleverly integrates multiple functions such as cleaning, crushing, extraction and concentration into one, thereby realizing the automation and continuity of the preparation process. This design not only greatly improves the preparation efficiency and reduces manual intervention, but also ensures the consistency and stability of the preparation process, providing a strong guarantee for the industrial production of traditional Chinese medicine preparations.

[0012] 2. Compared with the shortcomings of traditional devices in terms of medicinal material crushing and screening, the device of the present invention realizes efficient screening and secondary grinding of medicinal material powder through the unique design of crushing components and screening components. After the drum crushes the medicinal material, the screening component can automatically screen the powder to remove impurities and larger particles. At the same time, secondary grinding can be performed to reprocess unqualified particles, ensuring the fineness and uniformity of the medicinal material powder, and improving the quality and efficacy of traditional Chinese medicine preparations.

[0013] 3. Compared with the limitations of traditional devices in heating and temperature control, this solution innovatively installs heating components inside the drum and screening components, and realizes intelligent control through the control component. The heating component can moderately heat the medicinal materials during the crushing and screening process, which is conducive to the release and extraction of the effective ingredients in the medicinal materials. At the same time, the control component can accurately adjust the heating temperature and time to ensure the safety and effectiveness of the preparation process. This intelligent design not only improves the preparation efficiency, but also reduces energy consumption and costs, injecting new vitality into the modern production of Chinese medicine preparations.

[0014] Furthermore, the reset assembly includes a spring, one end of which is fixedly connected to the side wall of the slide groove, and the other side of the spring is fixedly connected to the outer side wall of the first power member. An airbag is sleeved on the outer side wall of the spring, and an air outlet is provided at the bottom of the airbag.

[0015] Beneficial effects: During the process of accumulating and releasing the spring, a micro airflow is generated through the inflation and deflation movement of the airbag. This airflow is like a natural cleaning tool, which can effectively blow the medicinal material particles on the screening component and promote the effective transfer of medicinal materials between the sieve plate and the extraction chamber. This not only avoids the accumulation and adhesion of medicinal material particles, but also speeds up the process of crushing and screening, and significantly improves the screening efficiency. Through the airflow flushing generated by the airbag, medicinal material particles that may have been difficult to move due to adhesion or accumulation can also be effectively transferred. This ensures that the medicinal material powder can be evenly distributed in the extraction chamber, providing more convenient conditions for subsequent extraction or pharmaceutical steps. Uniform distribution of medicinal materials helps to improve extraction efficiency and ensure the quality and efficacy of traditional Chinese medicine preparations. In the traditional screening process, manual cleaning and transfer of medicinal material particles may be required. The airbag design in this scheme reduces the need for manual intervention through automated airflow flushing. This not only reduces labor intensity, but also improves the degree of automation of the preparation process.

[0016] Furthermore, the screening assembly includes a first sieve plate and a second sieve plate, the first sieve plate is fixedly connected to the vertical rod of the first power member, the second sieve plate is fixedly connected to the vertical rod of the sliding block, the first sieve plate and the second sieve plate are staggered and clearance-matched, and leakage holes are provided on the first sieve plate and the second sieve plate, and the diameter of the leakage hole on the first sieve plate is larger than the diameter of the leakage hole on the second sieve plate.

[0017] Beneficial effects: The difference in the diameter of the leak holes on the first sieve plate and the second sieve plate allows the medicinal powder to undergo two different levels of screening when passing through the two layers of sieve plates. This graded screening method can more effectively remove impurities and larger particles in the medicinal powder and improve the screening accuracy. At the same time, the staggered arrangement and clearance fit design make the flow of medicinal powder between the sieve plates smoother, reducing the possibility of blockage and accumulation. The staggered arrangement and clearance fit design make the flow of medicinal powder between the sieve plates more efficient. At the same time, the graded screening method of the two-layer sieve plates can reduce the repeated processing of medicinal powder and improve production efficiency. This not only reduces the preparation cost, but also shortens the preparation cycle.

[0018] Furthermore, a driving member is installed at the connection between the cleaning chamber and the crushing chamber, and a baffle is coaxially fixedly connected to the output shaft of the driving member, and the baffle is slidably matched with the side wall of the outer shell. A collecting tube is connected to the bottom of the cleaning chamber, and the collecting tube is connected to a recovery chamber at one end away from the cleaning chamber. The recovery chamber is located on one side of the extraction chamber, and the extraction chamber is connected to a condenser. The end of the condenser away from the extraction chamber passes through the recovery chamber and is connected to the concentration chamber. A water bath chamber is provided outside the extraction chamber, and the water bath chamber is connected to the recovery chamber. Valves are provided at all connecting points, and the valves are opened and closed by control components.

[0019] Beneficial effects: During the extraction process, the cleaning liquid collected in the recovery chamber is used as a condensation medium to effectively absorb and condense the steam generated from the extraction chamber. This design not only improves the condensation efficiency and ensures the stability and quality of the condensate, but also realizes the reuse of the cleaning liquid and reduces resource waste. At the same time, the heat released during the condensation process is absorbed by the cleaning liquid in the recovery chamber, further improving the energy utilization efficiency. After the extraction is completed, the cleaning liquid in the recovery chamber is discharged into the water bath chamber, which plays a preheating role. This design helps to accelerate the temperature rise process of the liquid in subsequent extraction or processing steps, reducing energy consumption and time costs. Through preheating, thermal energy can be used more effectively and the energy efficiency of the overall preparation process can be improved. Valves are provided at all connections and are opened and closed by control components. This design makes the preparation process more flexible and controllable, and the parameters and sequence of each step can be adjusted according to the characteristics and needs of different medicinal materials. At the same time, automated control reduces the need for manual intervention and improves the stability and reliability of the preparation process.

[0020] Furthermore, a condensation plate is fixedly connected to the top of the concentration chamber, collection tanks are connected on both sides of the condensation plate, the concentration chamber is connected to a vacuum pump, and temperature sensors and a number of heating elements are installed on the inner walls of the concentration chamber. The temperature sensors and heating elements are connected to the control component signal, and the control component turns on and off the heating elements and controls the power through the monitoring data of the temperature sensor.

[0021] Beneficial effects: The design of the condensation plate enables the steam in the concentration chamber to be quickly condensed into liquid, thereby improving the concentration efficiency. At the same time, the setting of the collection tank facilitates the collection and transfer of the condensate, avoiding the waste and pollution of the condensate. This design not only ensures the stability and efficiency of the concentration process, but also improves the overall performance of the preparation device. By connecting the vacuum pump, a certain vacuum degree can be formed in the concentration chamber, thereby reducing the boiling point of water, so that the medicinal material extract can be quickly concentrated at a lower temperature. This vacuum concentration method not only improves the concentration speed, but also reduces energy consumption and reduces the preparation cost. The coordinated use of the temperature sensor and the heating element realizes the precise control of the temperature in the concentration chamber. The control component can open and close the heating element and adjust the power according to the monitoring data of the temperature sensor, so as to ensure that the concentration process is carried out within a suitable temperature range. This precise temperature control helps to improve the quality and stability of the concentrate.

[0022] Furthermore, a feed port is provided on the top wall of the cleaning chamber, and a cover body for closing the feed port is installed at the feed port. A stirring assembly is installed in the cleaning chamber, and the stirring assembly includes a second power member, which is fixedly connected to the top wall of the cleaning chamber. The output shaft of the second power member is coaxially fixedly connected to the stirring shaft, and a plurality of stirring rods are fixedly connected to the stirring shaft.

[0023] Beneficial effects: The feed port opened on the top wall of the cleaning chamber makes it convenient and quick to add materials such as medicinal materials. At the same time, the cover installed at the feed port can effectively close the cleaning chamber to prevent the material from splashing out or external impurities from entering during the stirring and cleaning process, ensuring the cleanliness and safety of the cleaning process. The design of the stirring component can achieve full stirring of the materials in the cleaning chamber. This stirring action helps to accelerate the mixing and reaction between the material and the cleaning liquid, thereby improving the cleaning efficiency. At the same time, stirring can also make it easier to clean the dirt and impurities on the surface of the material, ensuring the cleaning quality. The setting of the stirring component in the cleaning chamber makes the cleaning and pretreatment process of the medicinal materials more efficient. The stirring action can accelerate the removal of dirt and impurities on the surface of the medicinal materials, providing cleaner and more uniform materials for subsequent steps such as crushing, screening and extraction. This not only improves the preparation efficiency, but also ensures the quality and efficacy of Chinese medicine preparations.

[0024] Furthermore, the concentration chamber is provided with a material taking port, a cover for closing the material taking port is installed at the material taking port, and a handle is fixedly connected to the cover.

[0025] Beneficial effects: The setting of the material taking port makes it easy to take out the concentrated liquid medicine from the concentration chamber. By opening the cover, the operator can easily access the concentrate and perform the material taking operation. This design not only improves the convenience of taking materials, but also avoids the contamination of the concentration chamber and the concentrate during the material taking process. The cover is designed to close the material taking port, ensuring the sealing of the concentration chamber when the material is not needed. This sealing performance helps to prevent the concentrate from volatilizing, oxidizing or being contaminated by the outside during storage, thereby ensuring the quality and stability of the concentrate. The handle design on the cover makes it easier for the operator to apply force when opening or closing the cover, avoiding safety accidents caused by improper operation. At the same time, the handle can also serve as a heat insulation layer between the operator and the concentration chamber to prevent burns due to contact with the high-temperature concentration chamber during the material taking process.

[0026] Furthermore, a control panel is embedded in the outer wall of the shell, and the interior of the control panel is electrically connected to the control component. The control panel is provided with a display screen and operation buttons. The display screen is used to display the working status, temperature and pressure parameters of each chamber, and the operation buttons are used to manually control the opening and closing of each component and adjust related parameters.

[0027] Beneficial effects: The display screen can display the working status, temperature and pressure parameters of each chamber in real time, so that the operator can intuitively understand the operation of the preparation device. This intuitiveness helps operators to find and solve problems in a timely manner, ensuring the stability and efficiency of the preparation process. At the same time, the setting of the operation buttons allows operators to easily manually control the opening and closing of each component and adjust related parameters, improving the convenience and flexibility of operation. The operation buttons and display screen design on the control panel enable operators to monitor and operate the preparation device at a safe distance. This design helps to reduce the direct contact of operators with dangerous environments such as high temperature and high pressure, reducing safety risks. At the same time, the control panel can also set safety alarms and emergency shutdown functions to further ensure the safety of equipment and operators.

[0028] A method for preparing a Chinese medicine preparation for invigorating the spleen and activating blood circulation, which is applied to the preparation device for the Chinese medicine preparation for invigorating the spleen and activating blood circulation, comprises the following specific steps:

[0029] Step 1: Put the medicinal materials and cleaning liquid into the cleaning chamber, clean the medicinal materials, collect the cleaning liquid into the recovery chamber after cleaning, and place the medicinal materials into the crushing chamber;

[0030] Step 2: After the medicinal materials enter the crushing chamber, they are initially crushed. After the initial crushing, they fall onto the screening component, which crushes the medicinal materials and dries them at the same time;

[0031] Step 3: The medicinal material powder after preliminary crushing is preliminarily screened through the first sieve plate of the screening component, and the medicinal material particles fall onto the second sieve plate. The screening component performs secondary grinding on the medicinal material particles between the first sieve plate and the second sieve plate, and the completely crushed medicinal material powder enters the extraction chamber;

[0032] Step 4: Add a solvent into the extraction chamber and perform extraction by heating in a water bath. After the extraction is completed, introduce the extract into the recovery chamber through a condenser tube;

[0033] Step 5: Start the vacuum pump and the heating element to heat and concentrate the extract in the concentration chamber. The concentrated extract is taken out through the material taking port and poured into the preparation molding equipment for preparation molding treatment.

[0034] Beneficial effects:

[0035] 1. The cleaning chamber cleans the medicinal materials, effectively removing dirt and impurities on the surface of the medicinal materials, providing clean raw materials for subsequent steps. At the same time, the cleaning liquid is collected in the recovery chamber, realizing the reuse of resources and reducing environmental pollution. The medicinal materials are initially crushed and dried in the crushing chamber, providing suitable particle size and humidity conditions for the subsequent extraction steps, improving the extraction efficiency.

[0036] 2. The crushing component crushes the medicinal materials and dries them at the same time, ensuring the uniformity and stability of the medicinal powder. The screening component performs preliminary and secondary screening of the medicinal powder through the first and second sieve plates, ensuring that the particle size of the medicinal powder meets the extraction requirements and improving the extraction effect.

[0037] 3. In the extraction chamber, the extraction is carried out by adding solvent and heating in a water bath, which ensures the stability and efficiency of the extraction process. The condenser introduces the extract into the recovery chamber, avoiding the volatilization and loss of the extract and improving the extraction efficiency.

[0038] 4. By starting the vacuum pump and heating element to heat and concentrate the extract, the water and solvent in the extract are effectively removed, and the concentration and purity of the extract are improved. The concentrated extract is taken out through the material taking port and poured into the preparation molding equipment for preparation molding, which provides a strong guarantee for the preparation of high-quality traditional Chinese medicine preparations.

[0039] 5. The preparation method makes full use of the recovery chamber to recycle the cleaning liquid and the extraction liquid, reducing resource waste and environmental pollution. At the same time, by optimizing the extraction and concentration process, energy consumption and cost are reduced.

[0040] Furthermore, during the extraction process of step 4, a regulator is added, and the regulator is used to adjust the pH value of the extract during the extraction process.

[0041] Beneficial effects: By adjusting the pH value, the extraction environment can be made more suitable for the dissolution of the active ingredients in the medicinal materials. Some active ingredients have higher solubility at a specific pH value, thereby improving the extraction efficiency. Adjusting the pH value can also reduce the dissolution of unnecessary impurities or ineffective ingredients in the medicinal materials, making the extract purer and helping to improve the quality of the final product. Some medicinal ingredients are prone to decomposition or deterioration in an overly acidic or alkaline environment. By adjusting the pH value, these ingredients can be protected from destruction, ensuring the stability and integrity of the active ingredients in the extract. The appropriate pH value helps to maintain the active ingredients in the medicinal materials and ensure that the extract has the expected pharmacological effect.

[0059] The method for preparing a Chinese medicine preparation for invigorating the spleen and activating blood circulation is applied to the preparation device for the Chinese medicine preparation for invigorating the spleen and activating blood circulation, and the specific steps are as follows:

[0060] Step 1: Place the medicinal materials and cleaning liquid into the cleaning chamber, clean the medicinal materials, collect the cleaning liquid into the recovery chamber after cleaning, and place the medicinal materials into the crushing chamber.

[0061] Step 2: After the medicinal materials enter the crushing chamber, they are initially crushed. After the initial crushing, they fall onto the screening component, which crushes the medicinal materials while also drying them.

[0062] Step 3: The medicinal powder after preliminary crushing is preliminarily screened through the first sieve plate of the screening component, and the medicinal particles fall onto the second sieve plate. The screening component performs secondary grinding on the medicinal particles between the first sieve plate and the second sieve plate, and the completely crushed medicinal powder enters the extraction chamber.

[0063] Step 4: Add solvent to the extraction chamber and perform extraction by heating in a water bath. After the extraction is completed, introduce the extract into the recovery chamber through a condenser. During the extraction process, add a regulator to adjust the pH value of the extract during the extraction process.

[0064] Step 5: Start the vacuum pump and the heating element to heat and concentrate the extract in the concentration chamber. The concentrated extract is taken out through the material taking port and poured into the preparation molding equipment for preparation molding treatment.

[0065] The specific implementation process is as follows: Put the medicinal materials into the cleaning chamber 101. In this embodiment, the medicinal materials selected are: Codonopsis pilosula, Atractylodes macrocephala, Poria cocos, Euonymus fortunei, Sanguisorba officinalis, Eupatorium fortunei, Alismatis orientalis, Hedyotis diffusa, Pteris vicifolia, Aucklandia lappa and Radix Glycyrrhizae. At the same time, pour the cleaning liquid (the cleaning liquid in this embodiment is water) into the cleaning chamber 101 to cover the medicinal materials and ensure the cleaning effect. After the medicinal materials are cleaned in the cleaning chamber 101 for a period of time, the dirt and impurities on the surface of the medicinal materials are effectively removed. The valve of the pipe mouth of the collection tube 13 is opened by the operation button on the control panel 24, and the cleaning liquid flows into the recovery chamber 105 through the collection tube 13.

[0066] After cleaning is completed, the step of crushing the medicinal materials is performed next. The cylinder 11 is turned on by the operating button on the control panel 24, and the piston rod of the cylinder 11 is retracted, driving the baffle 12 connected thereto to retract to a preset position in the side wall of the housing 1. Under the action of gravity, the medicinal materials in the cleaning chamber 101 smoothly fall into the crushing chamber 102 below. When the medicinal materials are completely dropped in, the baffle 12 is closed again by the control panel 24 to prevent the medicinal materials from splashing during the crushing process.

[0067] When the control component receives the instruction to close the baffle 12, it will start the first motor 3 at the same time, and the output shaft of the first motor 3 drives the drum 4. When the drum 4 rotates, it will perform grinding motion along the inner wall of the crushing chamber 102. At this time, the medicinal material has fallen into the gap between the outer wall of the drum 4 and the inner wall of the crushing chamber 102. As the drum 4 continues to rotate, friction is generated between its outer wall and the medicinal material, gradually grinding the medicinal material into powder, and the medicinal material that is initially crushed into powder falls directly onto the first sieve plate 9.

[0068] Because the connecting rod 5 is eccentrically connected to the drum 4, when the drum 4 rotates, the sliding block 6 is driven to reciprocate through the connecting rod 5. Since reset components are installed on both sides of the first motor 3 and the sliding block 6, the springs 8 in these reset components will generate a reset force when the drum 4 drives the sliding block 6 to slide in the second chute 202. This reset force enables the first motor 3 to move back and forth in the first chute 201, and its moving direction is opposite to the moving direction of the sliding block 6. Since the first motor 3 and the sliding block 6 move in opposite directions, a relative movement is formed between them. This relative movement will drive the first sieve plate 9 and the second sieve plate 10 to move back and forth while they move. In this way, the medicinal materials on the first sieve plate 9 will be continuously screened as the sieve plate moves back and forth, and the medicinal materials that are initially crushed into powder will fall through the leak holes on the first sieve plate 9 to the second sieve plate 10 below or the extraction chamber 103 of the next layer. The medicinal materials falling between the first sieve plate 9 and the second sieve plate 10 will be crushed for a second time by the friction force generated by the back and forth movement of the first sieve plate 9 and the second sieve plate 10. With the continuous screening and crushing of the medicinal materials between the first sieve plate 9 and the second sieve plate 10, medicinal material powder with relatively uniform particle size can be obtained in the end.

[0069] While the crushing is in progress, the heating component is started by the control component. When the heating component is working, heat is released, and the heat is transferred to the medicinal materials through the roller 4 and the screening component. Since the medicinal materials are constantly subjected to mechanical forces during the crushing process, their internal cell structure is destroyed, and the water and other components in the cells are more easily released. At the same time, the heating effect accelerates the evaporation and diffusion of these components, making the medicinal materials gradually dry and loose. In addition, heating can also promote the dissolution and extraction of effective ingredients in medicinal materials. The effective ingredients of some medicinal materials are more easily released from the cells under heating conditions and combined with the solvent, thereby improving the extraction efficiency.

[0070] During the crushing process, the spring 8 in the reset component accumulates and releases, which drives the airbag set outside the spring 8 to inflate and deflate. When the spring 8 releases energy and pushes the sliding block 6 or related components to move, the airbag expands accordingly, and the inside of the airbag is filled with air through the air outlet as it expands. When the spring 8 accumulates power, the airbag is compressed, and the gas inside it is quickly blown out through the air outlet. This airflow with a certain speed and pressure, like a miniature storm, can effectively blow the medicinal material particles on the screening component (such as the first sieve plate 9 and the second sieve plate 10). Driven by the airflow, these medicinal material particles will more easily fall off the surface of the sieve plate and be blown into the extraction chamber 103 below. In particular, those medicinal material particles that may have been difficult to move due to adhesion or accumulation can also be effectively transferred under the flushing of this airflow. In this way, the effective transfer of medicinal materials between the sieve plate and the extraction chamber 103 is promoted. This not only helps to speed up the crushing and screening process, but also ensures that the medicinal material powder can be evenly distributed in the extraction chamber 103, providing more convenient conditions for subsequent extraction or pharmaceutical preparation steps.

[0071] In the extraction chamber 103, an appropriate amount of solvent (such as water, ethanol, etc.) is added, and the extraction process is started through the control panel 24. During the extraction process, an appropriate amount of acid or alkali can be added to adjust the pH value to improve the extraction efficiency. By heating in a water bath, the effective ingredients in the extract will gradually dissolve and diffuse into the solvent. During the extraction process, when the condenser 14 passes through the recovery chamber 105, the cleaning liquid collected in the recovery chamber 105 is used as a condensation medium. Since the cleaning liquid usually has a certain temperature and chemical composition, it can effectively absorb and condense the steam generated from the extraction process. This process not only reduces the temperature of the steam and converts it into a liquid state, but also further cools the condenser 14 through heat exchange, thereby ensuring the stability and efficiency of the condensation effect. After the extraction is completed, the cleaning liquid in the recovery chamber 105 completes its mission as a condensation medium and is then discharged into the water bath chamber 106. At this time, these cleaning liquids used by the condensation medium still have a certain temperature, so they play a preheating role in the water bath chamber 106. The preheating effect helps to accelerate the temperature rise process of the liquid in the subsequent extraction or processing steps, reducing energy consumption and time costs. In addition, discharging the cleaning liquid in the recovery chamber 105 into the water bath chamber 106 also helps to maximize the utilization of resources. After the extraction is completed, the extraction liquid is introduced into the concentration chamber 104 through the condenser 14 .

[0072] Start the vacuum pump and evacuate the concentration chamber 104 to reduce the boiling point in the extract and improve the concentration efficiency. At the same time, start the heating element through the control panel 24 to heat the concentration chamber 104. The temperature sensor monitors the temperature in the concentration chamber 104 in real time and adjusts the power of the heating element according to the preset parameters. During the concentration process, the water and volatiles in the extract are evaporated, leaving the concentrated extract. The condensation plate 15 on the top of the concentration chamber 104 can effectively collect and condense the steam escaping from the concentration chamber 104, and then the collection tank 16 is responsible for receiving and storing the condensate dripping from the condensation plate 15 to ensure that the condensate does not flow back to the concentration chamber 104, thereby avoiding possible pollution and efficiency loss. After the concentration is completed, turn off the heating element and the vacuum pump. Open the handle on the cover 23, take out the concentrated extract through the material taking port 22, and pour it into the preparation molding equipment for subsequent preparation molding processing.

[0073] Embodiment 2:

[0074] As attached Figure 5 As shown, the difference from Example 1 is that a stirring assembly is installed in the cleaning chamber 101, and the stirring assembly includes a second power member. In this embodiment, the second power member is a second motor 19, and the second power member is fixedly connected to the top wall of the cleaning chamber 101. The output shaft of the second power member is coaxially fixedly connected to the stirring shaft 20, and a plurality of stirring rods 21 are fixedly connected to the stirring shaft 20.

[0075] The specific implementation process is as follows: During the cleaning of the medicinal materials, the second motor 19 is started by pressing the operation button on the control panel 24. As the second motor 19 is started, its output shaft begins to rotate, thereby driving the stirring shaft 20 to rotate together. The stirring rod 21 on the stirring shaft 20 also begins to stir the medicinal materials and cleaning liquid in the cleaning chamber 101. During the stirring process, the medicinal materials are fully stirred and turned over, so that the cleaning liquid can evenly penetrate into all parts of the medicinal materials, thereby effectively removing dirt and impurities on the surface of the medicinal materials. At the same time, the shear force of the stirring rod 21 also helps to peel off the attachments on the surface of the medicinal materials, further improving the cleaning effect.

[0076] After the cleaning is completed, the operator can turn off the second motor 19 and stop the stirring process by pressing the operation button on the control panel 24. At this time, the medicinal materials in the cleaning chamber 101 have been cleaned and are ready for subsequent extraction or processing steps.

[0077] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
