STUDY ON THE SIMULATION AND TEST OF MIXED FLOW GRAIN DRYER

Mathematical modeling and computer simulation of grain drying are the major emphasis of grain drying research in China Agricultural University. In this paper research on simulation of mixed flow grain dryers had been accomplished. Mathematical model of MFGD had been established. The developed software had been used in analysis, design and optimization of mixed flow grain dryers. Effect of air temperature, air flow rate, size and location of air duct on the drying rate and energy consumption was discussed and analyzed. Experimental research was carried out to validate the simulation results. Emphasis was put on the Influence of air duct size distribution and number of rows on the performance of mixed flow grain dryer.
