摘　　要：采用超滤技术去除茶皂素水提液中的大分子物质 ,用适宜的膜 ,在工作温度 2 5℃时 ,就工作压力对膜通量的影响进行了研究分析 ,根据其过程特征 ,提出了茶皂素水提液体系超滤过程三段传质模型。The operating procedure of removing polymer from tea saponin by ultrafiltration was studied. The effects of operating pressure on the flux were mainly investigated. Under the condition of processing temperature 25℃, the three-step model of transferring substance in tea saponin ultrafiltration was put forward.
