Abstract

The invention discloses a floating-type high-extraction-rate supercritical extraction system for the preparation of traditional Chinese medicine, belonging to the field of supercritical extraction. A floating-type high-extraction-rate supercritical extraction system for traditional Chinese medicine preparation The setting of the two-way floating flexible frame with fluid and floating on the liquid surface, when the temperature rises and the pressure is reduced to remove carbon dioxide, the self-elevating expansion ball expands and floats when heated, and at this time, it can drive the screw rod in the supercritical water containing the extract. The fluid moves vertically upwards, thereby producing a certain stirring effect on the supercritical fluid containing the extract. At the same time, under the impact of the overflowing gaseous carbon dioxide, the screw rod can swing laterally, further increasing the stirring amplitude, and then Compared with the process of spontaneously releasing gaseous carbon dioxide in the prior art, the speed of the overflow of gaseous carbon dioxide is accelerated, thereby shortening the time required for drug extraction and significantly improving the overall pharmaceutical efficiency.

Description

technical field

[0001] The invention relates to the field of supercritical extraction, in particular to a floating type high extraction rate supercritical extraction system for the preparation of traditional Chinese medicine. Background technique

[0002] The state in which the pressure and temperature of the substance exceed its critical pressure (Pc) and critical temperature (Tc) at the same time, or the state in which the substance's contrast pressure (P / Pc) and contrast temperature (T / Tc) are greater than 1 at the same time is called the supercritical state of the substance. There are three phases of any substance—gas phase, liquid phase, and solid phase. The point at which the liquid and gas phases are in equilibrium is called the critical point. The temperature and pressure at the critical point are called critical temperature and critical pressure (the critical temperature and critical pressure of water are 374° C. and 21.7 MPa, respectively). Different substances ...
