Research on process parameter optimization and process intelligent control is an important element in the design and development of grain drying equipment. Existing methods mostly use simulation, device experiments or field experiments to obtain data, which have large differences with the actual drying results or the experimental process is time-consuming and vulnerable to interference. In this study, with reference to the process and structure of large continuous grain drying production equipment, a continuous grain drying simulation experimental system was developed and designed, including grain feeding equipment, dryer main body, grain discharge equipment, waste heat recovery, condensing device, hot air equipment and measurement and control system, which can simulate the grain drying operation process. This system can also optimize the drying process parameters, and carry out indoor grain drying quality change law, energy consumption law and production efficiency. The system can be used as the first-line staff post. The system could be used as the pre-service training for the workers on the production line, the experimental teaching of related majors in universities and colleges and the experimental research system of scientific research institutions.
