[0024] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner, and thus only show components related to the present invention.

[0025] Please refer to Figure 1-4 , a Chinese medicinal material extraction equipment, including a heating tank 1 and an evaporation tank 2 and a purification tank 4 under negative pressure. The evaporation tank 2 is arranged in the heating tank 1, and the purification tank 4 and the evaporation tank 2 are fixed by a connecting seat 3. Of course, the connecting seat 3 can also be detachable, so that the purification tank 4 can be separated from the evaporation tank 2; the evaporation tank 2 and the purification tank 4 are connected by a siphon tube 9, a steam delivery pipe 8 is provided on the evaporation tank 2, and a condenser 6 is provided on the top of the purification tank 4. The bottom end of the condenser 6 extends into the purification tank 4, and the end of the steam delivery pipe 8 is connected to the condenser 6. The inner wall of the purification tank 4 is provided with a plurality of medium-frequency ultrasonic generators 41, and a filter cartridge 42 for storing Chinese medicinal materials is provided in the purification tank 4. A discharge pipe 11 is provided at the bottom of the heating tank 1.

[0026] In this embodiment, the interlayer between the heating tank 1 and the evaporation tank 2 forms a sealed heating chamber 22, a heat-conducting medium is provided in the heating chamber 22, and a solvent is provided in the evaporation tank 2; the heat-conducting medium can be water or heat-conducting oil, and the solvent can be water or ethanol, etc., preferably ethanol; the discharge pipe 11 passes through the heating chamber 22 and is connected to the evaporation tank 2; in addition, heating rods 10 are provided on both sides of the discharge pipe 11.

[0027] The heat transfer medium is preferably thermal oil to better transfer temperature.

[0028] When in use, the evaporation tank 2 and the purification tank 4 extract the internal air through the pipeline, so that the whole is in a negative pressure state (close to vacuum), approximately -0.08MPa. In the negative pressure / vacuum environment, the solvent is more easily condensed and recovered. The overall sealing also ensures that the organic solvent will not evaporate into the external environment, reducing solvent loss; At the same time, since the pressure is negative and close to a vacuum, the boiling point of the liquid (ethanol in the evaporator 2) decreases significantly as the ambient pressure decreases. At this time, it is only necessary to lower the heating temperature of the heating rod 10 to boil the ethanol solvent. Such low-temperature operation can protect heat-sensitive components, prevent proteins and enzymes in the drug from dispersing, denaturing, or inactivating at high temperatures, reduce damage to heat-sensitive substances, and improve the yield, purity, and biological activity of the extract.

[0029] Specifically, when the heating rod 10 is in operation, the heating tank 1 and the heat-conducting medium (water or heat-conducting oil) inside are heated and heated. Since the heating chamber 22 is sealed, the heat-conducting medium does not volatilize. Therefore, as the temperature rises, the solvent (water or ethanol, etc.) in the evaporation tank 2 is heated and boiled to produce steam through the principle of heat transfer. At this time, the steam is transmitted upward along the steam delivery pipe 8 and enters the condenser 6 (condenser). After the steam contacts the condenser 6, it forms liquid, and the liquid will drip down along the condenser 6 onto the Chinese medicinal materials. As the liquid level in the purification tank 4 gradually rises, the liquid will cover the filter cartridge 42 and the Chinese medicinal materials inside; when the liquid level rises to the uppermost end of the siphon tube 9, the liquid flows into the evaporation tank 2 through the siphon tube, thereby completing the first extraction.

[0030] Similarly, as the solvent in the evaporation tank 2 evaporates, the pure solvent enters the condenser 6 again, condenses to form a liquid, and drips again to fully mix with the Chinese medicinal materials. The organic matter in the Chinese medicinal materials is dissolved into the solvent again. As the solution continues to rise, after exceeding the siphon tube 9, the solution is siphoned into the evaporation tank 2 again, completing the second extraction.

[0031] This process is repeated, and a steady supply of fresh solvent comes into thorough contact with the Chinese medicinal materials, thereby completely and fully extracting the effective ingredients in the Chinese medicinal materials.

[0032] The discharge port 7 at the rear of the purification tank 4 is then opened to completely discharge the residual Chinese medicinal material, and the end cap is closed. As evaporation continues, the solvent containing the precipitated Chinese medicinal components in the evaporation tank 2 evaporates, and the pure solvent continuously evaporates to the condenser 6. After cooling, it forms a pure solvent again and gathers in the purification tank 4. As the solvent decreases, a high concentration of Chinese medicinal precipitate gradually forms, achieving the purpose of concentrating and forming a paste. Finally, the effective components are discharged through the discharge pipe and collected. The entire process is isolated from the outside, preventing the extract from being contaminated by bacteria, air, dust, etc.

[0033] Furthermore, due to the setting of the ultrasonic generator 41, a cavitation effect will be generated, that is: the ultrasonic generator 41 will cause the gas in the tiny space in the solvent to undergo a sharp change between negative pressure and positive pressure while emitting waves, that is, a negative pressure is generated in an instant to shrink the gas, and then a strong positive pressure is generated in another instant, thereby tearing the bubbles apart; the bubbles will produce air explosions and explosive energy during the tearing process, and the explosive energy can cause violent vibrations to the Chinese medicinal materials dissolved in the solvent, thereby absorbing the effective ingredients in the Chinese medicinal materials into the solvent.

[0034] This process will not cause overall high temperature and high pressure, and has high extraction efficiency, and will not cause loss of effective substances in the medicinal materials during extraction.

[0035] Please refer again Figure 4 The interior of the connecting base 3 is hollow and is provided with an L-shaped connecting pipe 31. One end of the L-shaped connecting pipe 31 is connected to the purification tank 4, and the other end extends outward to be connected to one end of the siphon pipe 9. The other end of the siphon pipe 9 extends downward to be connected to the evaporation tank 2. The siphon pipe 9 is in an inverted U-shape, so the solvent will stay in the purification tank 4, increasing the extraction time. When the liquid level height meets the siphoning requirement, it will enter the evaporation tank 2.

[0036] In order to ensure that the solvent is fully in contact with the Chinese medicinal materials and to prevent the Chinese medicinal materials from floating and diffusing in the purification tank 4, the Chinese medicinal materials are placed in the filter cartridge 42; Figure 5-8 The filter cartridge 42 includes a filter cartridge 421 , a top cover 422 is provided on the top of the filter cartridge 421 , and a step grate 424 is provided on the bottom. The step grate 424 protrudes into the filter cartridge 421 .

[0037] The circumference of the filter cartridge 421 and the surface and circumference of the step grate 424 are all provided with filter holes 425 .

[0038] The top cover 422 can be detached from the filter cartridge 421. When in use, Chinese medicinal materials are placed into the filter cartridge 421 and the top cover 422 is closed. At this time, the Chinese medicinal materials will not float around, and it is also convenient to take out the Chinese medicinal residues together.

[0039] Since a step grate 424 is provided in the filter cartridge 421 and a plurality of steps are provided on the step grate 424, after the Chinese medicinal materials are placed in the filter cartridge 421, they can stay on the plurality of steps. This arrangement can facilitate the distribution of the Chinese medicinal materials, avoid concentrated accumulation of the medicinal materials, increase the contact area between the solvent and the Chinese medicinal materials, and facilitate purification.

[0040] As a preferred solution, a groove 423 is provided on the surface of the top cover 422 , and a filter hole 425 is also provided on the bottom surface of the groove 423 . The groove 423 is located directly below the condenser 6 .

[0041] The cross-section of the groove 423 is circular, and the inner diameter is larger than the outer diameter of the condenser tube 6; therefore, the condensed liquid in the condenser tube 6 can directly drip into the groove 423, enter the filter cartridge 421 through the filter hole 425, and then seep out through the filter holes on the filter cartridge 421 and the step grate 424. This can greatly increase the contact time between the solvent and the Chinese medicinal materials, thereby improving the efficiency of drug purification.

[0042] Based on the above embodiment, the evaporation tank 2 is further provided with an observation window 21 , and the purification tank 4 is provided with a feeding port 5 and a discharging port 7 .

[0043] The observation window 21 can observe the process inside the device, the status of solution extraction, the amount of solution extracted, etc. The feeding port 5 can be used to feed Chinese medicinal materials into the interior, and the discharging port 7 is used to remove the Chinese medicinal residues after extraction.

[0044] The diameter of the discharge port 7 is larger than that of the filter cartridge 42 , and can meet the requirements of taking and placing the filter cartridge 42 .

[0045] It can be understood that when Chinese medicinal materials are added at the feeding port 5, it is easy for the Chinese medicinal materials to spill outside the filter cylinder 42; to ensure that the medicinal materials completely enter the filter cylinder 42, the Chinese medicinal materials can be directly placed into the filter cylinder 42 from the outside, and finally placed together into the purification tank 4 at the discharge port 7.

[0046] Based on the above embodiment, during the extraction process, the discharge pipe 11 is closed by a valve, and the feeding port 5 and the discharge port 7 are covered by end covers to ensure that they are in a sealed state during use.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
