天然产物多级膜与高压差提取器联用的设计与开发

天然产物高压差提取分离浓缩器的核心技术在于多级膜与高压差提取器的联用设计。它是通过合理的结构设计、流程与自控设计以及排污和安装设计，将高压差提取、微滤澄清、超滤分离、纳滤或反渗透浓缩、在线清洗、过程自控等多技术单元进行组合，形成完整的技术及成套装备，可较好地实现中药提取物全过程低温（20℃以下）制备，达到洁净区流程化生产的目的。

Design and Development of the Combined Multi-membrane and High-pressure Differential Extract Combined Technique for Natural Products

The core technique of the high-pressure differential extraction, separation and concentration equipment for natural products is the design of multi-level membrane and high-pressure differential extraction in combination. Based on the rational structrul design, process and automation design, as well as sewerage and installation design, this technique makes up various technical steps, including high-pressure differential extraction, microfihration clarification, ultrafihration, nonofihration or reverse osmosis concentraion, on-line cleaning process, and procedure auto control technique, thus forming a complete set of techniques and equipments. This makes it possible to prepare the traditional Chinese medicine extract at low temperature （20 ℃ or less） during the entire process, thus fulfilling the scheduled production in a clean area.
