The invention discloses pharmaceutical supercritical extraction equipment. The pharmaceutical supercritical extraction equipment comprises a base, wherein first support legs are welded on one side ofthe top end of the base; an extraction tank is fixedly mounted at the top ends of the first support legs; a medicine feeding pipe is connected with one side of the extraction tank; a gas inlet pipe isconnected with the bottom of the extraction tank and extends into the extraction tank; a connecting pipe is connected with the other side of the extraction tank and connected with a separation tank;the bottom end of the separation tank is welded on the other side of the top end of the base through second support legs; a medicine discharging pipe is connected with the bottom of the separation tank; a separation cavity is formed in the separation tank and communicated with the connecting pipe. According to the pharmaceutical supercritical extraction equipment, a spray tray of a disc-shaped structure is arranged, spray nozzles are circumferentially and uniformly distributed on the spray tray, so that the coverage area of sprayed supercritical CO2 fluid is larger, extracting and mixing workis greatly accelerated, and working efficiency is improved.
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 substance that is neither gas 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. , is similar to a liquid, and its viscosity is closer to that of a gas. In the process of pharmaceuticals, supercritical extraction equipment needs to be used for extraction. However, when the existing supercritical extraction equipment extracts, the supercritical carbon dioxide fluid and the liquid medicine The extraction mixing efficiency is low, and the separation efficiency after extraction is also slow, so it cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to provide a kind of supercritical ...
