An Automatic Moisture G)ntrol for Continuous Grain Dryers

lation of the drying process and of proposed control systems was used to determine the optimum control system. A ñnal prototype control system was developed using a modi- ñed dielectric moisture meter as the moisture sensor and a control unit with proportional, reset, and rate modes. This system was tested on a full-scale continuous-flow dryer.
