Problems solved by technology

[0004] The extraction rate of existing supercritical extraction devices generally depends on the extraction effect of the extraction tank and the separation effect of the separator. Due to the characteristics of supercritical fluid, it is easy to achieve a high separation rate from the operation of changing temperature and pressure, even Multi-stage separation and rectification are used to improve the separation effect, but most of the extraction kettles still use simple hangi

Abstract

The invention discloses a suspension point contact type supercritical extraction device. The invention belongs to the technical field of supercritical extraction. A hanging basket static extraction mode in a traditional extraction kettle can be abandoned; the deformation characteristic of an empty throwing material receiving film is utilized; contained materials are shaken and thrown in the air; apowdery material is promoted to keep a dispersed suspended state; then, supercritical fluid sequentially passes through a limited space to be in full contact with the materials; the extraction rate of effective substances is obviously improved; through the characteristics of the empty throwing material receiving film and the assisting action of an assisting hanging piece, on one hand, the material dispersion effect is improved, meanwhile, the posture can be changed by overturning, the material is in contact with the supercritical fluid, the materials are fully extracted, and extraction dead corners are not prone to occurring; on the other hand, the situation that the extraction effect is affected due to the static adhesion phenomenon of the powdery materials can be avoided; the one-way extraction rate of the materials can be greatly increased, and the extraction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of supercritical extraction, and more specifically relates to a suspended point contact type supercritical extraction device. 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 a very ideal extraction agent. In the process of pharmaceuticals, supercritical extraction equipment is generally used to extract the effective substances of Chinese herbal medicine. The principle of supercritical carbon dioxide fluid extraction and separation process is to use the relationship between the dissolving ability of supercritical fluid and its density, that is, to use the influence of press...
