Design of Steeping Control System for Corn Wet Milling Process

Abstract:

In order to increase starch yield, it is important to adopt counter-current steeping method and control the steeping temperature under limits which is appropriate for corn wet milling process. Firstly, the configuration of steeping temperature control system and steps of counter-current steeping for corn wet milling process is introduced in this paper. Secondly, the hardware design of steeping control system for corn wet milling process is developed. As a part of starch production DCS control system, a C/S structure which using industrial computer as upper computer and using S7-400 PLC as lower computer is adopted. Finally, the steeping temperature control program based on fuzzy-PID control and algorithm of automatic steeping is presented. The real-time operation shows that the control system given by the paper can meet the requirements of corn steeping production.
