摘　　要：设计了一种适于液体原料超临界 CO2 萃取的装置 ,很好地解决了液体原料萃取时原料的倒流、萃取釜的清洗及原料的准确计量问题 ,并且大大加强了 CO2 穿透液体原料的能力及在原料中的均匀分布 ,提高了萃取效率 ,缩短了萃取时间 。A device used for liquid material extraction by supercritical carbon dioxide was designed. The device can solve the problems existing in liquid material supercritical CO 2 extraction, which are liquid material backflow, difficulty of extraction container cleaning and accurately weighing of material. Supercritical CO 2 can be forced into and evenly distributed in liquid material, which leads to high extraction efficiency and short extraction time. The extraction system has a more effect on compositions extracting and a better quality retention of biological material activities.
