Abstract

The invention discloses supercritical extraction equipment for pharmacy, and belongs to the field of supercritical extraction equipment. According to the scheme of the supercritical extraction equipment for pharmacy, supercritical carbon dioxide can be sprayed out through a spray head and mixed with liquid medicine, the mixture is guided into a separation tank through a connecting pipe to be separated, carbon dioxide and liquid medicine organic matter are mixed and guided into a water tank through an exhaust pipe after separation, then through impact on a gas bag during guiding, the gas bag shakes in the water tank to stir water in the water tank, the organic matter is dissolved in water, the carbon dioxide is guided into a gas storage bag through a gas guide pipe, then the gas storage bag is gradually enlarged, a secondary magnet ball repels a main magnet ball and after expansion so as to enable the gas bag to stir more violently in the water tank, separation of the organic matter and carbon dioxide is improved, and finally, the gas bag is inserted into the gas inlet pipe, gas is sprayed out through the spray head through extrusion to be mixed with newly added liquid medicine, and the effect of repeated utilization is achieved.

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...
