Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine extraction technology, and in particular to a novel traditional Chinese medicine extraction and concentration device. Background Technology

[0002] Traditional Chinese medicine extraction involves extracting the pharmacologically active components from medicinal herbs, removing impurities and ineffective components, and providing raw materials for subsequent drug research and development, formulation production, etc. Concentration can reduce the volume of the extract and increase the concentration of the effective components, which facilitates subsequent formulation processing, such as making tablets, capsules, oral liquids, etc.

[0024] Reference Figure 1-4This utility model discloses a novel traditional Chinese medicine extraction and concentration device, comprising: an ultrasonic extraction tank 1, a concentration component 25, and a liquid collection component 26. A second liquid level pipe 24 is fixedly connected to the side surface of the ultrasonic extraction tank 1.

The operator can determine the solvent volume through the second liquid level pipe 24, turn on the ultrasonic generator of the ultrasonic extraction tank 1, and perform ultrasonic extraction on the traditional Chinese medicine inside the ultrasonic extraction tank 1. The ultrasonic waves generate cavitation in the solvent, forming many tiny bubbles. When the bubbles burst instantaneously, they generate powerful shock waves and microjets, causing the cell walls of the traditional Chinese medicine to rupture, thereby making it easier for the effective components to dissolve. In the solvent, an ultrasonic extraction tank 1 has a discharge pipe 2 at its bottom. A first valve 3 is installed inside the discharge pipe 2.

The material inside the ultrasonic extraction tank 1 passes through the discharge pipe 2, the first connecting pipe 4, the second connecting pipe 5, the fourth connecting pipe 10, the circulation pump 11, and the fifth connecting pipe 12. The material enters the concentration tank 7. The upper surface of the sight glass 6 is fixedly connected to the concentration tank 7.

The side surface of the concentration tank 7 is fixedly connected to the third connecting pipe 8. The end of the third connecting pipe 8 away from the concentration tank 7 is fixedly connected to the steam generator 9. An appropriate amount of water is added to the steam generator 9, and the steam generator 9 is turned on. The generated steam enters the concentration tank 7 through the third connecting pipe 8. The temperature generated by the steam generator 9 is set by an external controller, between 45 and 90 degrees Celsius. Low-temperature extraction can avoid the loss of active ingredients in traditional Chinese medicine. The second connecting pipe 5... The side surface of the concentrator 7 is fixedly connected to the fourth connecting pipe 10. The end of the fourth connecting pipe 10 away from the second connecting pipe 5 is fixedly connected to the circulation pump 11. The side surface of the concentrator 7 is fixedly connected to the fifth connecting pipe 12. The end of the fifth connecting pipe 12 away from the concentrator 7 is fixedly connected to the circulation pump 11. The side surface of the concentrator 7 is fixedly connected to the first liquid level pipe 13. The liquid level in the concentrator 7 can be observed through the first liquid level pipe 13. The valve on the first connecting pipe 4 and the second valve 27 are closed. The circulation pump 11 is started. The concentrated Chinese medicine liquid in the concentrator 7 enters the concentrator 7 again through the sight glass 6, the fourth connecting pipe 10, the circulation pump 11 and the fifth connecting pipe 12 for circulation flow, which can prevent local overheating.

[0025] The liquid collection assembly 26 includes a sixth connecting pipe 14, a seventh connecting pipe 16, a gas-liquid separator 17, an eighth connecting pipe 18, a condenser 19, and a condensate collection tank 20. A pressure reducing valve 15 is installed inside the sixth connecting pipe 14. The end of the sixth connecting pipe 14 furthest from the pressure reducing valve 15 is fixedly connected to the concentration tank 7. The right surface of the pressure reducing valve 15 is fixedly connected to the seventh connecting pipe 16. The right surface of the seventh connecting pipe 16 is fixedly connected to the gas-liquid separator 17. The side surface of the gas-liquid separator 17 is fixedly connected to the eighth connecting pipe 18. The end of the eighth connecting pipe 18 furthest from the gas-liquid separator 17 is fixedly connected to the condenser 19. The end of the condenser 19 furthest from the eighth connecting pipe 18 is fixedly connected to the condensate collection tank 20. The steam discharged from the concentration tank 7 passes through the gas-liquid separator 17, the eighth connecting pipe 18, and the condenser 19 before entering the condensate collection tank 20 for collection. A vacuum gauge 21 is installed above the condensate collection tank 20. Through the vacuum gauge 21, the operator can determine whether the equipment is maintained at a suitable vacuum level to ensure that the condenser 19 can effectively cool the steam into liquid. The lower surface of the steam generator 9 is fixedly connected to the main frame 22, which supports the equipment. An electrical box 23 is installed above the main frame 22.

[0026] Working Principle: During use, the pre-treated Chinese medicinal materials (including screening, washing, and pulverizing) and an appropriate amount of extraction solvent are added to the ultrasonic extraction tank 1. The top cover of the ultrasonic extraction tank 1 is closed, and the ultrasonic generator of the ultrasonic extraction tank 1 is turned on to perform ultrasonic extraction on the Chinese medicinal materials inside the ultrasonic extraction tank 1. The ultrasonic waves generate cavitation in the solvent, forming many tiny bubbles. When the bubbles burst instantaneously, they generate powerful shock waves and micro-jet streams, causing the cell walls of the Chinese medicinal materials to rupture, thus making it easier for the effective components in the Chinese medicinal materials to dissolve into the solvent. After extraction is completed, the bottom valve of the ultrasonic extraction tank 1 is opened, and the circulation pump 11 is started. The material inside the ultrasonic extraction tank 1 enters the concentration tank 7 through the discharge pipe 2, the first connecting pipe 4, the second connecting pipe 5, the fourth connecting pipe 10, the circulation pump 11, and the fifth connecting pipe 12. An appropriate amount of water is added to the steam generator 9, and the steam generator 9 is turned on. The generated steam enters the concentration tank 7 through the third connecting pipe 8. The temperature generated by 9 is set by an external controller. Low-temperature negative pressure extraction is used in the process. The valves on the first connecting pipe 4 and the second valve 27 are closed, and the circulation pump 11 is started. The concentrated liquid in the concentration tank 7 is circulated back into the concentration tank 7 through the fourth connecting pipe 10, the circulation pump 11 and the fifth connecting pipe 12 to prevent local overheating. The steam generated during the concentration of the Chinese medicine concentrate is discharged from the sixth connecting pipe 14 by opening the pressure reducing valve 15. The discharged steam is collected in the condensate collection tank 20 after passing through the gas-liquid separator 17, the eighth connecting pipe 18 and the condenser 19. This equipment can make the effective components in Chinese medicine more fully dissolved in the solvent. Compared with the traditional process, ultrasonic extraction can improve the extraction rate of Chinese medicine and shorten the extraction time. Moreover, ultrasonic extraction uses low-temperature negative pressure extraction, which can avoid the destruction of the effective components in Chinese medicine during the concentration process. In addition, vacuum low-temperature concentration is used in the process, and the extracted Chinese medicine concentrate can be stored at room temperature.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
