Description

Technical Field

[0001] The utility model relates to the technical field of extraction devices, in particular to a natural plant effective component extraction device based on supercritical fluid extraction. Background Art

[0002] Supercritical fluid extraction is a new type of extraction and separation technology. It uses 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 an extractant to extract specific components from liquids or solids to achieve the purpose of separation. With the rapid development of modern science and technology, the application of natural plant active ingredients in medicine, cosmetics, food and other fields is becoming more and more extensive. Traditional extraction methods such as solvent extraction, steam distillation, and pressing have problems such as low extraction efficiency, complex operation, and environmental pollution. In order to achieve efficient extraction effects, supercritical fluid extraction technology is usually used to replace traditional extraction technology.

[0003] When performing supercritical fluid extraction, it is usually carried out in the corresponding extraction device. Since supercritical fluid extraction requires the addition of supercritical fluid, and most supercritical fluids are liquid gases, the gas will return to gaseous state and be discharged to the outside as the pressure decreases. Most supercritical fluid extraction devices lack the defect of being able to dry and recycle the supercritical fluid that has returned to gaseous state. If this part of the gas is directly discharged to the outdoors, it will pollute the environment. At the same time, it will also cause waste. It needs to be re-prepared the next time it is used, wasting resources. In view of this, we propose a natural plant active ingredient extraction device based on supercritical fluid extraction.
