Research progress on control strategies for grain drying process
The cultivation,planting,and harvesting of grain production have been basically mechanized,but the post-harvest drying and processing of grain is weak.Grain drying is a complex heat and mass transfer process,in order to fully ensure the quality of grain drying,grain drying operation parameters need to be regulated,i.e.,the drying process was optimally controlled to obtain high drying quality and drying efficiency.On the basis of exist-ing literature at home and abroad,this paper first gave a brief description of grain drying equipment,especially the classification of hot air convection grain dryers,and summarized and analyzed the current research status of grain drying process control strategy from two aspects,namely,traditional control strategy and intelligent control strategy,and the related urgent problems and future development directions were outlooked to provide reference for the optimization of grain drying process control.
