Abstract

The invention discloses a supercritical extraction equipment for pharmacy, which belongs to the field of supercritical extraction equipment. It is a supercritical extraction equipment for pharmacy. This scheme can realize that the supercritical carbon dioxide is sprayed out by the nozzle and mixed with the liquid medicine, and the supercritical carbon dioxide is sprayed out through the connecting pipe. Import it into the separation tank to separate it. After the separation, the carbon dioxide and the liquid organic matter are mixed and introduced into the water tank through the exhaust pipe, and then through the impact on the air bag during introduction, the air bag shakes in the water tank to clean the water in the water tank. Agitation makes the organic matter dissolve in water, while carbon dioxide is introduced into the air storage bag through the air duct, and then the air storage bag gradually increases, and after expansion, the repulsion of the main magnetic ball by the secondary magnetic ball makes the air bag agitate more in the water tank Intensive, in order to improve the separation of organic matter and carbon dioxide, and finally insert it into the intake pipe, and squeeze the gas through the nozzle to mix with the newly added liquid medicine, so as to achieve the effect of repeated use.

Description

technical field [0001] The invention relates to the field of supercritical extraction equipment, in particular to a pharmaceutical supercritical extraction equipment. Background technique [0002] Supercritical is a supercritical fluid, which is a state of matter that is neither gaseous nor liquid between gas and liquid. This substance can only exist when its temperature and pressure exceed the critical point. The density of supercritical fluid is relatively high. Large, similar to liquid, and its viscosity is closer to gas, so supercritical fluid is an ideal extraction agent. The principle of supercritical CO2 fluid extraction (SFE) separation process is to use the dissolving ability of supercritical fluid and its The relationship between density is carried out by using the influence of pressure and temperature on the dissolving ability of supercritical fluid. The components of high and low molecular weight and molecular weight are extracted in sequence. Of course, the ext...
