Abstract—Feed contains adequate moisture,and feed
moisture is very important quality indicator in the food
administrator all over the world. Based on the research on the
dynamic changes and their related factors of the waterage in the
various feed drying stages,this article has put forward the
automati control methods and designed the automatic control
system based on PLC. he development and implementation
process of fan drying control system, using Step 7 programming
software to control system design. it has solved many problems
such as low accuracy,large damages,high cost and so on.By
optimizing the design and debugging to improve the accuracy of
the control system and to improve the efficiency of the drying
unit,reducing the operator’s operational difficulties.
