Simulation and Validation of Microwave-Assisted Fluidized Bed Drying of Soybeans

摘要: A general mathematical model of heat and mass transfer was developed to simulate the microwave-assisted fluidized bed drying bulk grain. The solved using well-known Runge-Kutta-Gill method. is capable predicting moisture content soybean as well air parameters (i.e., temperature content) during drying. values mean relative deviation (MRD) were less than 8 10% for prediction grain outlet parameters, respectively, which reflects an acceptable accuracy. In comparison with conventional soybean, led 83.39–98.07% savings in time 82.07–95.22% specific energy consumption when reducing from 18.32 12% (db).
