离心式连续逆流提取机的研究

中草药的提取、分离是决定中药生产水电汽能耗和收得率的关键，是实现中药生产现代化的关键。论文所提出的离心式连续逆流提取机分为渗漉和浸渍逆流提取段、离心分离段，其中，提取段可根据需要设置加热夹套对料液进行加热，加速有效成份的渗出过程，缩短提取时间；同时该设备也可以附加上超声装置，利用超声波的空化效应进一步的强化浸出效果。本设计方案结合了渗漉式和浸渍式的混合方式，具有浓度梯度良好、提取效率高、适应多种药材形状等特点，可实现连续高效提取中药材有效成份，高效节能多级连续逆流提取符合中药生产中GMP规范要求，是中药提取技术发展的方向。

Research on centrifugal continuum adverse current distill device for Chinese Medicine

Distilling and separating the effective ingredients from Chinese herb for Chinese Medicine are the key factors to realize the Chinese Medicine modernization, There are a lot of traditional methods to get the effective ingredients from raw herbs, such as decoction, infusing, seeping, refluence, distillation etc, However, multilevel continuum adverse current distillation is more effective and energy saving, which accord with the request of GMP.
