A high-efficiency supercritical extraction equipment for pharmaceuticals

Abstract

The invention discloses a high-efficiency supercritical extraction equipment for pharmacy, which belongs to the field of supercritical pharmacy. It is a high-efficiency supercritical extraction equipment for pharmacy. After the extraction, the pressure-reducing and temperature-raising treatment is performed by setting a dislocation magnetic ball net. , so that when the gaseous carbon dioxide overflows upwards, the dislocation floating net can be lifted up as a whole, making it gradually approach the dislocation magnetic net. The net presents a dynamic up and down dislocation shape, which effectively increases the gap between the two dislocated floating balls, facilitating the overflow of gaseous carbon dioxide. On the one hand, under its dynamic action, it accelerates the flow speed of gaseous carbon dioxide and accelerates its outward overflow speed , Compared with the existing technology, the extraction efficiency is significantly accelerated. On the other hand, it can effectively intercept the small particles of the extracted effective substances carried by the adsorbed gaseous carbon dioxide when it overflows, thereby effectively improving the extraction rate.

Description

technical field [0001] The invention relates to the field of supercritical pharmacy, in particular to a high-efficiency supercritical extraction equipment for pharmacy. Background technique [0002] The state in which the pressure and temperature of a substance exceed its critical pressure (Pc) and critical temperature (Tc) at the same time, or the state in which the relative pressure (P / Pc) and relative temperature (T / Tc) of a substance are greater than 1 at the same time is called The supercritical state of the substance. There are three phases of any kind of matter—gas, liquid, and solid. 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 the critical temperature and critical pressure (the critical temperature and critical pressure of water are 374°C and 21.7MPa, respectively). Different substances require different pressures and temperatures for their critical poin...

Problems solved by technology

[0005] Supercritical carbon dioxide extraction is to change carbon dioxide into supercritical fluid, use carbon dioxide supercritical fluid as a solvent to dissolve the substances to be extracted, and then change the carbon dioxide in the supercritical fluid into gaseous carbon dioxide by raising the temperature and reducing the pressure, so that the obtained The extract is more pure, so many medicines are extracted in this way, so that the obtained extract does not contain other impurities. In this process, although the temperature rise will accelerate the release of carbon dioxide, the release of carbon dioxide is an autonomous release, so the release speed Relatively slow, resulting in a relatively long time for the entire drug extraction process, resulting in low drug extraction efficiency, and when carbon dioxide vaporizes, when it overflows, it is easy to carry some particles of effective substances, resulting in the loss of extracted effective substances. so that the extraction rate is not high
