Design of Automatic Control System for Grain Drying
With the continuous development of the grain processing industry,the automatic control requirements in the grain drying process are becoming higher and higher.In order to improve grain drying efficiency and reduce loss and en-ergy consumption,this paper presents a new PLC-based grain dryer automatic control system.The system uses PLC to realize the precise control of grain drying temperature,humidity and other parameters,and has a variety of safety guaran-tees such as overheating protection,sound and light alarm,etc.The design scheme of grain dryer automatic control system based on PLC can efficiently and automatically control grain drying,improve drying efficiency and reduce grain loss and energy consumption.
