摘　　要：提出了一种利用纳滤膜来连续浓缩大豆低聚糖的新工艺.介绍了20 t/h大豆低聚糖纳滤连续浓缩工艺流程及控制要求,设计了基于PLC的过程控制系统.控制系统结构采用Siemens的TP170B触摸屏作为人机界面,S7 200 PLC、DR 20调节器和MM 430变频器作为控制核心.通过在山东谷神应用结果表明,该工艺流程经济适用、运行稳定可靠、自动化程度高,能够满足连续生产的要求,提高了膜分离装置的运行效率.A novel nanofiltration concentration process for recovery of oligosaccharides from streamed soybean waste water is explored. Technical flow and control requirements for 20 t/h nanofiltration continuous process is introduced. One process control system based on PLC was designed. The control system is integrated by Siemens TP170B as human machine interface （HMI）, S7200, DR20 and MM430 as control center. It is proved by application in Shandong Gushen that the design can meet the technical requirements with availability, reliability and efficiency.
