DETAILED DESCRIPTION

[0052] The present invention will be further described in detail below with reference to the accompanying drawings.

[0053] refer to Figures 1 to 6 The Chinese medicine decoction and concentration all-in-one machine can automatically and intelligently extract the medicinal liquid. The medicinal liquid can be concentrated to a preset concentration or ointment state. It can be used in hospitals, pharmacies and other places.

[0054] The Chinese medicine decoction and concentration machine includes an extraction tank 2, a concentration tank 3, a first heating element 51, a second heating element 52, a negative pressure generator 4 and other components; the extraction tank 2 and the concentration tank 3 are both arranged on the top of the housing 1;

[0055] refer to Figure 2The extraction tank 2 is used to extract the medicinal liquid, and the medicinal liquid is extracted at normal temperature and pressure, which can ensure the stable extraction of the effective ingredients of the traditional Chinese medicine, thereby improving the quality of the traditional Chinese medicine decoction.

[0056] A first heating element 51 is provided below the extraction tank 2. The first heating element 51 may be a mica heating sheet for heating the extraction tank 2. A first heat insulating layer 61 is provided below the first heating element 51. The first heat insulating layer is a nano-aerogel felt for heat insulation.

[0057] A first cover 21 is provided on the top of the extraction tank 2. The first cover 21 can be made of glass or the like, and a sealing ring is provided on the edge thereof.

[0058] During liquid extraction, the Chinese medicine and clean water are placed in the extraction tank 2 and soaked for a period of time, or the soaked Chinese medicine is placed in the extraction tank 2. Then, the Chinese medicine is heated and boiled at normal pressure to obtain liquid medicine, and then the liquid medicine is transferred to the concentration tank 3.

[0059] Therefore, the extraction tank 2 extracts the medicinal liquid at room temperature and pressure, that is, decocting with high heat and keeping warm with low heat, etc. Compared with high pressure and high temperature extraction, it can ensure the stable extraction of the effective ingredients of traditional Chinese medicine, thereby improving the quality of traditional Chinese medicine decoction.

[0060] refer to Figure 3 and Figure 4 The concentration tank 3 is used to concentrate the liquid medicine to increase its concentration, and can also concentrate the liquid medicine into ointment.

[0061] A second heating element 52 is provided below the concentration tank 3;

[0062] An air inlet 33 is provided at one end of the concentration tank 3, and an air outlet 34 is provided at the other end of the concentration tank 3. The air outlet 34 is connected to the negative pressure generator 4, and an air valve 86 is provided at the air inlet 33.

[0063] The negative pressure generator 4 can cause negative pressure and airflow to be formed inside the concentration tank 3. That is, when the negative pressure generator 4 is working, it draws air outward, and a negative pressure is formed inside the concentration tank 3. At the same time, it causes gas to flow into the concentration tank 3 from the air inlet 33, and the gas inside the concentration tank 3 flows out from the air outlet 34 to form an airflow. It can be seen that the negative pressure generator 4 not only causes a negative pressure to be formed in the concentration tank 3, but also causes a flowing airflow to be formed inside the concentration tank 3.

[0064] Working principle of concentration tank 3:

[0065] The second heating element 52 heats the medicinal liquid. Due to the action of the negative pressure generator 4, a negative pressure is formed inside the concentration tank 3, which reduces the boiling temperature of the medicinal liquid. In this way, the medicinal liquid boils in a relatively low temperature and negative pressure environment, making the unstable effective components of traditional Chinese medicine less likely to volatilize, oxidize, and pyrolyze, and thus not polluting the environment. The effective components of traditional Chinese medicine dissolve quickly, but the boiling temperature is reduced, and the saturation of the steam is reduced, which affects the concentration efficiency. At this time, under the action of the negative pressure generator 4, a certain airflow is formed inside the concentration tank 3, which accelerates the flow of steam and enables the steam to be discharged from the concentration tank 3 in a timely manner. At the same time, after the steam is discharged in time, the steam seal in the tank is reduced, which can promote the faster conversion of water into steam. The relatively orderly flow of the airflow is conducive to the orderly flow and discharge of steam, which is conducive to improving the concentration efficiency. Therefore, compared with the existing sealed structure of the concentration tank 3, the open concentration tank 3 formed by the present application is more conducive to increasing the evaporation rate, thereby improving the concentration efficiency, and the negative pressure concentration is also conducive to energy saving.

[0066] The speed of water evaporation is affected by several factors:

[0067] The first factor is the negative pressure value. The higher the negative pressure value, the lower the boiling temperature and the lower the steam saturation. Refer to Table 1, that is, the steam saturation decreases as the boiling temperature decreases.

[0068] The second factor is the liquid surface area. The larger the liquid surface area, the greater the amount of water that turns into steam. That is, the amount of water that turns into steam increases with the increase of the liquid surface area.

[0069] The third factor is airflow. The faster the airflow speed, the faster the water turns into steam. That is, the speed at which water turns into steam increases with the increase of airflow speed.

[0070] Refer to Table 2, which shows the evaporation rate per unit time obtained from the experiment under different negative pressure values ​​with the liquid surface area remaining unchanged. Since the airflow is generated under the action of negative pressure, the greater the negative pressure value, the greater the corresponding airflow speed.

[0071] Table 1 is as follows:

[0072]

[0073] Table 2 is as follows:

[0074]

[0075] As can be seen from the data in Table 2, when the negative pressure value is set between 6kp and 20kp, the boiling temperature of the liquid medicine inside the concentration tank 3 is between 90 degrees and 99 degrees, and the evaporation rate is relatively high. This temperature range not only does not destroy the components of the liquid medicine during concentration, but also has a high concentration efficiency.

[0076] When the negative pressure value is set between 6kp and 10kp, the boiling temperature of the liquid medicine in the concentration tank 3 is between 95 degrees and 99 degrees, and the evaporation rate is high.

[0077] It can be seen that the conventional concentrator is a closed container, in which no airflow can be formed, and the concentration is performed at a negative pressure of about 40°. The present application forms an open container through the negative pressure generator 4 and the air inlet 33, and the concentration is performed at a negative pressure of about 95°. The steam saturation is higher, and an internal airflow is formed, and the concentration efficiency is higher.

[0078] In order to further increase the speed of evaporation and concentration, the liquid surface area of ​​the internal liquid of the concentration tank 3 is 1500cm 2 The above is conducive to forming a larger evaporation area, thereby increasing the evaporation speed or evaporation amount and improving the concentration efficiency.

[0079] Preferably, the liquid surface area of ​​the internal liquid of the concentration tank 3 is between 1800 cm 2 to 2200cm 2 In this way, the liquid area is larger, which is beneficial to improving the evaporation and concentration efficiency.

[0080] Therefore, it can be seen from Table 2 that the open concentration method, that is, realizing the flow of steam in the container during the concentration process and improving the concentration efficiency by expanding the liquid evaporation area, the experimental results are more than doubled compared with the traditional concentration efficiency.

[0081] refer to Figures 9 to 11 , the concentration tank 3 is in the shape of a rectangular parallelepiped or a cube, and the second heating element 52 is provided on the lower surface of the concentration tank 3;

[0082] The rectangular parallelepiped shape means that the length dimension L and the width dimension W are different, and the height dimension H is not limited. When the concentrator tank 3 is rectangular parallelepiped, an air inlet 33 is provided at one end of the concentrator tank 3 in the longitudinal direction, and an air outlet 34 is provided at the other end of the concentrator tank 3 in the longitudinal direction.

[0083] The cube shape means that the length dimension L and the width dimension W are the same, and the height dimension H is not limited; when the concentrator 3 is in a cube shape, the air inlet 33 and the air outlet 34 can be arranged along the length direction or the width direction;

[0084] Therefore, the concentrating tank 3 is in a rectangular parallelepiped or a cube shape, which is conducive to the orderly flow of airflow. Especially when it is in a rectangular parallelepiped shape, the airflow will flow along its length direction, and the flow of airflow will be orderly and stable.

[0085] For further reference, Figures 9 to 11When the concentrator tank 3 is rectangular, the ratio of its length L to width W is between 1.3 and 2.0, for example, approximately 1.5. Specifically, the length of the concentrator tank 3 can be between 500 and 600 mm, the width can be between 300 and 400 mm, and the height H can be between 150 and 200 mm. The concentrator tank 3 is rectangular with a relatively small height, forming a flat body. This allows it to hold more liquid medicine and create a larger liquid medicine surface, thereby increasing evaporation and concentration rates.

[0086] When the concentrating tank 3 is in a cubic shape, the length dimension L is the same as the width dimension W, and the height dimension H is smaller than the width dimension W.

[0087] refer to Figure 3 An air inlet 33 is provided at the middle of the upper surface 3a at one end portion in the longitudinal direction of the concentrating tank 3;

[0088] Two symmetrical air inlets 33 are provided on the upper surface 3a at the other end of the concentration tank 3 in the longitudinal direction, so that the gas flows from the air inlet 33 to the two air inlets 33 in a dispersed manner, driving more steam to flow to the air outlet 34 and be discharged from the air outlet 34.

[0089] The air inlet 33 may be provided with an air valve 86 , which may open or close the air inlet 33 and adjust the air intake volume and air intake speed, thereby adjusting the negative pressure value and air flow speed to a certain extent.

[0090] The negative pressure generator 4 is a fan, which can be appropriately adjusted in power, gear, etc. according to different working conditions to form different negative pressure values. The selection of the fan is conducive to control and adjustment. In addition, the fan consumes less power than the negative pressure machine and is more conducive to energy saving.

[0091] refer to Figure 10 The lower surface 3b of the concentration tank 3 is in a downwardly arched arc shape.

[0092] The arc-shaped lower surface 3b can improve the strength of the force, and when the concentration tank 3 forms a negative pressure, the arc-shaped lower surface 3b is not easy to deform. In addition, the arc-shaped lower surface 3b can increase the heat conduction area and improve the heat conduction efficiency.

[0093] refer to Figure 4 The second heating element 52 is a mica heating sheet. The second heating element 52 is provided on the lower surface 3b of the concentration tank 3. The mica heating sheet has a high heating efficiency, which can reach more than 90%, which is beneficial to energy saving.

[0094] The second heating element 52 is covered with a second heat-insulating layer 62 . The second heat-insulating layer 62 is a nano-aerogel felt. The nano-aerogel felt has an excellent heat-insulating effect and reduces heat transfer to the outside.

[0095] To further explain, a liquid outlet 32 ​​is provided on the lower surface 3 b of the concentration tank 3 , and a fifth solenoid valve 85 may be provided at the liquid outlet 32 ​​.

[0096] refer to Figure 12 and Figure 13 The Chinese medicine concentrated decoction machine also includes a condenser 91 and a preheating tube 92;

[0097] One end of the condenser 91 is connected to the air outlet 34, and the other end of the condenser 91 is connected to the air inlet of the negative pressure generator 4. The condenser 91 is a conventional technology, which is provided with a condensation tube and a condensation medium, and can cool the steam, thereby condensing the steam into water, reducing the water content of the gas, and forming a relatively dry gas;

[0098] One end of the preheating pipe 92 is connected to the air inlet 33, and the other end of the preheating pipe 92 is connected to the air outlet of the negative pressure generator 4;

[0099] The preheating tube 92 is serpentine and can be made of copper or aluminum. The preheating tube 92 is arranged below the second heating element 52. That is, the second heating element 52, the preheating tube 92 and the second insulation layer 62 can be arranged in sequence below the concentration tank 3. The second heating element 52 can heat the preheating tube 92.

[0100] Therefore, after the steam condenses in the condenser, it forms a relatively dry gas, which causes the temperature of the gas to drop, reduces the impact of heat on the negative pressure generator 4, and increases the service life of the negative pressure generator 4. The cooling water can be discharged through the outlet of the negative pressure generator 4, and then the preheating pipe 92 heats the gas. Finally, it flows back to the concentration tank 3, thereby forming a thermal circulating gas flow, ensuring that the temperature in the concentration tank 3 will not drop due to air circulation, thereby ensuring the increase in steam generation and concentration efficiency.

[0101] If the gas flows directly into the concentration tank 3 from the outside, the normal temperature of the gas is about 20 degrees, and the temperature difference is relatively large. The gas will absorb a large amount of heat, affecting the temperature inside the concentration tank 3, thereby affecting the concentration efficiency and being detrimental to energy saving. In addition, the water content of the external air is relatively high, which is not conducive to the evaporation of water in the liquid medicine.

[0102] Therefore, first, condenser 91 cools the steam to protect negative pressure generator 4. Second, the condensed gas becomes dry and has a low moisture content. This circulates into concentrator tank 3, increasing the evaporation rate of the liquid medicine, thereby improving concentration efficiency. Third, the circulating gas is heated to maintain the temperature within concentrator tank 3, ensuring concentration efficiency.

[0103] In summary, the concentration efficiency is affected by many factors such as negative pressure, air flow velocity, liquid surface area, and external air moisture content. This application comprehensively considers the above-mentioned factors and the interactions between them. Through experimental verification, it can effectively improve the concentration efficiency. Compared with traditional concentration efficiency, the efficiency can be more than doubled and energy-saving.

[0104] refer to Figure 3 An observation port 35 is provided on the upper surface 3 a of the concentration tank 3 , and a transparent second cover 36 is provided on the observation port 35 .

[0105] The observation port 35 can be used to observe the internal situation of the concentration tank 3. The second cover 36 can be made of glass or the like. The second cover 36 is detachable and sealed to the observation port 35 so that gas does not flow into the observation port 35 when negative pressure occurs. A sealing ring is provided on the edge of the second cover 36, which contacts the wall of the observation port 35 to form a sealed connection.

[0106] When performing small-dose concentration, the second cover 36 can be opened and the liquid medicine can be placed in the concentration tank 3 for concentration. When performing large-dose or automated concentration, the liquid medicine can be transported to the concentration tank 3 through a pipeline to achieve continuous operation.

[0107] The upper surface 3a of the concentration tank 3 is provided with reinforcing ribs, which can extend along the width direction of the concentration tank 3 or along the length direction of the concentration tank 3, thereby improving the strength of the concentration tank 3 and making the concentration tank 3 less likely to deform under negative pressure.

[0108] The extraction tank 2 and the concentration tank 3 can be connected in series through a pipeline. The delivery port 22 of the extraction tank 2 is connected to the liquid inlet 31 of the concentration tank 3. After the liquid medicine is extracted and transferred to the concentration tank 3, the extraction tank 2 can continue the second extraction of the liquid medicine or the extraction of another liquid medicine. The liquid medicine extraction and concentration can be carried out simultaneously to improve efficiency.

[0109] When the liquid medicine is transferred, the power for the transfer can be provided by the negative pressure generator 4, that is, the negative pressure generator 4 causes the concentration tank 3 to form a negative pressure. At this time, the air inlet 33 is closed, and the liquid medicine is sucked into the concentration tank 3 under the action of the negative pressure. In this way, the negative pressure generator 4 not only provides negative pressure and forms internal airflow during concentration, but also provides power when the liquid medicine is transferred.

[0110] In order to reduce manpower, improve efficiency and ensure quality, the Chinese medicine decoction and concentration machine realizes automated or intelligent production by setting relevant pipes, sensors, solenoid valves and other components.

[0111] refer to Figure 5 , comprising a first pipe 71, a second pipe 72 and a third pipe 73, wherein the first pipe 71, the second pipe 72 and the third pipe 73 form a three-way pipe structure;

[0112] The first pipe 71 is connected to the water source and is provided with a first solenoid valve 81;

[0113] The second pipe 72 is connected to the bottom delivery port 22 of the extraction tank 2. The second pipe 72 is provided with a flow meter 101 and a second solenoid valve 82. The extraction tank 2 is provided with a first temperature sensor 102.

[0114] The third pipe 73 is connected to the liquid inlet 31 of the concentration tank 3, and the third pipe 73 is provided with a third solenoid valve 83;

[0115] An air inlet 33 is provided at one end of the concentration tank 3, and an air outlet 34 is provided at the other end of the concentration tank 3. The air outlet 34 is connected to the negative pressure generator 4, and an air valve 86 is provided at the air inlet 33.

[0116] The concentration tank 3 is provided with a negative pressure sensor 103, a second temperature sensor 104 and a liquid level sensor 105;

[0117] refer to Figure 6 , further comprising a control panel 200, to which the first solenoid valve 81, the second solenoid valve 82, the third solenoid valve 83, the flow meter 101, the first temperature sensor 102, the negative pressure sensor 103, the air valve 86, the second temperature sensor 104, and the liquid level sensor 105 are all electrically connected. The control panel 200 is provided with a processing chip and may be provided with a screen, buttons, and indicator lights.

[0118] The steps for intelligent decoction and concentration of the Chinese medicine decoction and concentration machine are as follows:

[0119] S1. Soaking: Soak the Chinese medicine for the prescribed time, and then move the Chinese medicine and the soaking water into the extraction tank 2. The control panel 200 can set the amount of clean water to be input or execute according to the preset water amount, that is, replenish the water amount so that the water amount meets the decoction requirements. At this time, the first solenoid valve 81 is opened, the second solenoid valve 82 is opened, and the third solenoid valve 83 is closed. The flow meter 101 calculates the amount of clean water flowing into the extraction tank 2. When the water amount reaches the set value, the first solenoid valve 81 is closed, the second solenoid valve 82 is closed, and the third solenoid valve 83 is closed.

[0120] The soaking can be carried out in other containers to improve the use efficiency of the all-in-one machine.

[0121] S2, extraction: through the control panel 200, the first heating element 51 is started, and the Chinese medicine is boiled at normal pressure in the extraction tank 2 to obtain a medicinal liquid; wherein the program can be set to perform high-fire decoction and low-fire heat preservation, etc.;

[0122] During this period, the first temperature sensor 102 detects the temperature of the liquid medicine and feeds it back to the control panel 200. If the temperature of the liquid medicine exceeds a preset range, the control panel 200 adjusts the power of the first heating element 51 and may issue an alarm.

[0123] S3. Liquid transfer: The control panel 200 is used to start the negative pressure generator 4. At this time, the first solenoid valve 81 is closed, the second solenoid valve 82 is opened, the third solenoid valve 83 is opened, and the air valve 86 is closed. The negative pressure generator 4 evacuates air from the concentration tank 3, forming a negative pressure inside the concentration tank 3. The liquid medicine in the extraction tank 2 flows into the concentration tank 3 under the action of the negative pressure. After the liquid medicine transfer is completed, the third solenoid valve 83 is closed.

[0124] S4. Concentration: Control panel 200 activates second heating element 52, and negative pressure generator 4 continuously pumps air into concentrating tank 3. Valve 86 opens, creating negative pressure and airflow inside concentrating tank 3. Heated by second heating element 52, the liquid is concentrated at low pressure, forming a medicinal solution or ointment of a certain concentration. The steam is cooled by condenser 91, heated by preheating tube 92, and then circulated back to concentrating tank 3.

[0125] During this period, the negative pressure sensor 103 detects the internal negative pressure value of the concentration tank 3, and the second temperature sensor 104 detects the temperature value of the liquid medicine. The above negative pressure value and temperature value are fed back to the control panel 200. If the corresponding value exceeds the preset range, the control panel 200 can adjust the power of the second heating element 52 and / or the negative pressure generator 4, and can also issue an alarm;

[0126] When the liquid level of the medicinal liquid drops to a preset position, that is, when the ointment of the preset concentration is formed, the liquid level sensor 105 sends a signal to the control panel 200 , and according to the signal, the control panel 200 turns off the second heating element 52 and the negative pressure generator 4 .

[0127] Therefore, through the settings of the control panel 200, solenoid valve, flow meter 101 and corresponding sensors, an automatic and intelligent Chinese medicine decoction and concentration electric system is formed, which realizes automatic and intelligent Chinese medicine decoction and concentration, and completes the three-decoction and three-concentration process of high-fire decoction, low-fire insulation and delivery of the medicine soup for concentration through relevant procedures, thereby improving work efficiency.

[0128] refer to Figure 6 The device further includes a communication module 300, which is electrically connected to the control panel 200 and is connected to a terminal 400 via a wireless or wired connection. The terminal 400 may be a mobile phone, a computer, a tablet computer, or the like, and the wireless connection may be via Wi-Fi. The communication module 300 may transmit values ​​such as the water volume, temperature, and negative pressure during the Chinese medicine decoction and concentration process to the terminal 400 to achieve remote monitoring. The terminal 400 may also send command signals to the communication module 300 to remotely control the Chinese medicine decoction and concentration machine.

[0129] refer to Figure 6The communication module 300 can also be connected to the cloud server 500 in a wireless or wired manner, and the terminal 400 is connected to the cloud server 500 through the network, thereby realizing remote monitoring and control. The terminal 400 can realize remote monitoring in a variety of ways.

[0130] refer to Figure 7 and Figure 8 The Chinese medicine decoction and concentration machine further includes a fourth pipe 74. The first pipe 71, the second pipe 72, the third pipe 73, and the fourth pipe 74 form a cross-shaped four-way pipe. The fourth pipe 74 is provided with a fourth solenoid valve 84. Thus, the fourth pipe 74 is used for sewage discharge. The sewage from the extraction tank 2 can be discharged through the fourth pipe 74. The fourth solenoid valve 84 is normally closed and opens when sewage discharge is required.

[0131] In summary, this all-in-one Chinese medicine decoction and concentration machine achieves intelligent decoction and concentration of Chinese medicine through a decoction, concentration, and electronic control system, enabling remote monitoring. It can also simultaneously extract and concentrate Chinese medicinal ingredients. Unlike traditional closed concentration methods, this machine employs a novel open concentration method, which enables steam flow and thermal circulation within the container during the concentration process, and improves concentration efficiency by expanding the liquid evaporation area. Experimental results show that this machine more than doubles the efficiency of traditional decoction machines and is energy-efficient, making it a suitable replacement for the decoction machines currently used in domestic hospitals and pharmacies.

[0132] refer to Figure 14 , a decoction room, comprising the above-mentioned Chinese medicine decoction and concentration integrated machine, and also comprising a packaging machine 10;

[0133] The Chinese medicine decoction and concentration machine and the packaging machine 10 are arranged in the same room, for example, in the decoction room;

[0134] The liquid outlet 32 ​​of the concentration tank 3 is connected to the packaging machine 10 through the fifth pipe 75. The liquid outlet 32 ​​is provided with a fifth solenoid valve 85. During the execution of the liquid medicine transfer and concentration steps, the fifth solenoid valve 85 is normally closed. The fifth pipe 75 can be connected to the negative pressure generator 4 to transport the ointment to the packaging machine 10 in a negative pressure manner. The packaging machine 10 performs actions such as bagging and sealing the ointment.

[0135] refer to Figure 15The decoction and concentration steps will generate a large amount of heat, causing the temperature in the decoction room to be high, making the operators uncomfortable. In order to discharge the heat generated by decoction and concentration to the outside of the decoction room, an independent negative pressure cooling system can be set up. The negative pressure cooling system includes a negative pressure generator 4. The air inlet end of the negative pressure generator 4 is respectively connected to the air outlet 34 of multiple concentration tanks 3, so that one negative pressure generator 4 provides negative pressure for multiple concentration tanks 3, providing negative pressure power for liquid transfer and negative pressure concentration. At the same time, the air inlet end of the negative pressure generator 4 can also be respectively connected to the top of multiple extraction tanks 2, and the air outlet end of the negative pressure generator 4 extends to the outside of the decoction room. A solenoid valve is provided between the negative pressure generator 4 and the concentration tank 3, and a solenoid valve is provided between the negative pressure generator 4 and the extraction tank 2. In this way, the negative pressure generator 4 can discharge the heat generated by multiple machines during decoction and concentration to the outside.

[0136] To improve the environmental friendliness of emissions, a condenser 91 is installed at the air inlet or outlet of the negative pressure generator 4. This cools the heat before discharging it outdoors, reducing environmental pollution and impact. Furthermore, the condenser 91 cools the steam, protecting the negative pressure generator 4 and extending its service life. The negative pressure generator 4 and condenser 91 can be installed as a module outside the cooking room, making construction and maintenance more convenient.

[0137] Therefore, the decoction room is equipped with a Chinese medicine decoction and concentration integrated machine and a packaging machine 10 at the same time. Through decoction, concentration, electronic control system and negative pressure cooling system, automatic and intelligent Chinese medicine decoction, concentration and packaging are realized, which improves work efficiency and cools heat for environmental protection.

[0138] In addition, decoction, concentration and negative pressure cooling form a modular architecture. The negative pressure cooling system can connect multiple parallel decoction and concentration machines in series to form a centralized negative pressure supply structure, which simplifies and facilitates the construction of the decoction room.

[0139] Finally, the cooking room can monitor the status of each process step at the same time, and conduct remote monitoring through terminals 400 such as mobile phones and computers, forming a smart production space.

[0140] In summary, the integrated Chinese medicine decoction and concentration machine and decoction room have the following features: 1. It fully replicates the traditional three-step decoction process of traditional Chinese medicine at room temperature and pressure, maintaining and preserving the therapeutic effects of traditional Chinese medicine. 2. By adding a concentration step, the quality of traditional Chinese medicine is improved. 3. Smart decoction reduces the error rate associated with manual operation, saving manpower. 4. The use of new heating and insulation materials increases the electric heating efficiency from less than 50% to approximately 93%. This aligns with the development philosophy of energy conservation and environmental protection. It has enormous potential for expansion and should be considered a new type of productive force.

[0141] The above disclosure is only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
