Description

Technical Field

[0001] The utility model relates to the technical field of supercritical extraction production, in particular to supercritical extraction pressurizing equipment. Background Art

[0002] Supercritical extraction is a process that subjects a solvent to high pressure and high temperature conditions in order to effectively extract target components from plant extracts, natural products or chemicals. In the supercritical state, the fluid has both the diffusivity and low viscosity of a gas and the solubility of a liquid, which makes it exhibit some unique properties when extracting target compounds. The extraction solvent needs to be processed before extraction. The extraction solvent (usually liquid carbon dioxide) is compressed by a pump or compressor to reach the high pressure required for the supercritical state, and the temperature is raised by a heating system so that the whole reaches the high temperature and high pressure state required for the supercritical state.

[0003] However, the air pump will vibrate and wear during operation. If the design is unreasonable or it is used for a long time, the sealing performance may be reduced. Improper operations such as replenishing compressed air and replacing the pump tube may also damage the integrity of the air pump itself and its interfaces, affecting the air tightness. In addition, the extraction solution flows unevenly in the reaction equipment, which may cause some areas to receive less heat or be heated for a longer time, resulting in uneven temperature and causing the reaction temperature to be too high or too low. This will cause the reaction to be abnormal or even cause the reaction to fail, thus affecting the accuracy and reliability of the experiment. Utility Model Content
