Supercritical extraction device is a kind of equipment that uses supercritical fluid to separate and extract substances. Supercritical fluid is a state between gas and liquid, which has the advantages of high diffusion, low surface tension and adjustable density, so it is widely used in the material separation process in the fields of chemical industry, food, medicine and so on.

The supercritical extraction device is mainly composed of a pressure control system, a supercritical fluid supply system, a material inlet and outlet system, a separation system and a recovery system. First, the feed material is fed into the supercritical extractor together with the supercritical fluid by the pressure control system. Under the condition of high pressure and high temperature, the supercritical fluid dissolves and diffuses with the substance, so as to realize the separation and extraction of the substance.

The supercritical extraction apparatus has several advantages. First of all, the supercritical fluid has a high solubility, which can extract substances more comprehensively and improve the extraction efficiency. Secondly, the temperature and density of the supercritical fluid can be controlled by adjusting the pressure to achieve selective separation and extraction of substances. Again, the supercritical extraction process without the use of organic solvents, will not cause pollution to the environment, in line with the requirements of sustainable development. In addition, supercritical extraction technology can also achieve continuous separation and extraction of different substances and improve production efficiency.

Supercritical extraction devices are widely used in many fields. In the chemical industry, it can be used to separate and extract organic compounds, natural products, etc. In the food industry, it can be used to extract natural pigments and spices from plants. In the pharmaceutical industry, it can be used to extract the active ingredients in drugs and improve the purity and activity of drugs. In addition, supercritical extraction technology can also be applied to the field of environmental protection for the treatment of organic pollutants in wastewater.

In short, the supercritical extraction device is a kind of equipment that uses supercritical fluid to separate and extract substances. It has high extraction efficiency, selectivity and environmental friendliness, and is widely used in chemical industry, food, medicine and other fields. It is of great significance to improve production efficiency and reduce environmental pollution.
