Problems solved by technology

[0003] When using supercritical fluid for extraction, the temperature of the supercritical fluid is too low, and the dissolution rate of the substance in the supercritical fluid is relatively slow. The temperature of the critical fluid rises, and the supercritical fluid changes from a liquid state to a gaseous state, which wastes the supercritical fluid and is not conducive to the extraction of substances

Abstract

The invention relates to the field of extracting, and specifically relates to a supercritical fluid extracting device. The device comprises a fixing frame, a storing mechanism, a barrel body, a driving mechanism, a mixing mechanism, a filtering mechanism, an extracting mechanism and a feeding port, wherein the mixing mechanism is mounted in the barrel body and comprises injecting heads, an air pipe, a rubber rod, a funnel and a compressing plate; the inner sidewall of the barrel body is fixedly connected to the funnel; the top surface of the funnel is connected to the compressing plate throughthe elastic rubber rod; the top surface of the compressing plate is propped against the driving mechanism; the bottom end of the funnel is equipped with the air pipe; the injecting heads which are distributed at equal intervals are arranged on the sidewall of the air pipe; and the filtering mechanism is in thread connection with the bottom end of the barrel body. According to the device, air in the barrel body is compressed and blown into the materials and the supercritical fluid, so that the dissolving rate of the materials in the supercritical fluid is increased, and moreover, the temperature of the supercritical fluid does not increase.

Description

technical field [0001] The invention relates to the field of extraction, in particular to a supercritical fluid extraction device. Background technique [0002] Supercritical fluid extraction is a new type of extraction and separation technology. It uses a supercritical fluid, that is, a fluid in a thermodynamic state with a temperature higher than the critical temperature and a pressure higher than the critical pressure, as the extraction agent. Extract specific components from liquids or solids for separation purposes. [0003] When using supercritical fluid for extraction, the temperature of the supercritical fluid is too low, and the dissolution rate of the substance in the supercritical fluid is relatively slow. As the temperature of the critical fluid rises, the supercritical fluid changes from a liquid state to a gaseous state, which wastes the supercritical fluid and is not conducive to the extraction of substances. The invention provides a supercritical fluid ext...
