Problems solved by technology

[0004] However, due to the fixed direction and position of the supercritical fluid ejection in the existing extraction equipment, the supercritical extraction agent and the extraction liquid cannot be fully contacted and fused, resulting in low extraction efficiency and serious waste of supercritical fluid, which is not conducive to Save extraction cost, for this reason, propose a kind of supercritical extraction equipment for pharmaceutical

Abstract

The invention discloses pharmaceutical supercritical extraction equipment which comprises a supporting frame, a supporting plate is fixedly mounted at the top of the supporting frame, a supporting column is fixedly mounted at the top of the supporting plate, a motor is fixedly mounted at the top of the supporting column, a belt is arranged at the output end of the motor, and a transmission shaft is connected-one end of the belt. A transmission gear is fixedly mounted at the top of the transmission shaft, a connecting shaft is mounted in the transmission gear in a penetrating manner, a driven gear is meshed with the edge of the transmission gear, a positioning shaft is mounted in the driven gear in a penetrating manner, a clamping rod is mounted at the top of the driven gear in a penetrating manner, and a bayonet is formed in the surface of the clamping rod; and a liquid cylinder is fixedly mounted at the top of the clamping rod. The liquid cylinder drives the liquid spraying pipe-rotate and spray liquid in the horizontal direction, so that the liquid is fully mixed with an extracting agent sprayed by the spraying head, the contact area between the extracting agent and the liquid agent is greatly increased, the extraction efficiency is improved, and the extraction cost is saved.

Description

technical field [0001] The invention relates to the field of pharmacy, in particular to a supercritical extraction device for pharmacy. 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. A supercritical fluid has a higher density, similar to a liquid, and its viscosity is closer to that of a gas. So supercritical fluid is a very ideal extraction agent. [0003] The solvent strength of the supercritical fluid depends on the temperature and pressure of the extraction. Utilizing this characteristic, only by changing the pressure and temperature of the extractant fluid, different components in the sample can be extracted successively according to the solubility in the fluid. [0004] However, due to the fixed direction and position of the supercritical fluid ejection in the existing ...
