摘要：
The moisture content of brown rice wet particles was characterized based on discrete element simulation. Firstly, the angle of repose under different moisture content was determined by physical experiment, and the regression equation of moisture content and angle of repose was established, R2 = 0.9718. Then, the mathematical model between the angle of repose and the key discrete element parameters was established by discrete element simulation experiments, R2 = 0.9938. Finally, a mathematical model between moisture content and key discrete element parameters was established, and the maximum relative error of simulated angle of repose and physical angle of repose was verified to be 3.09%. The results show that the constructed wet grain discrete element parameter model of brown rice can be used for simulation research, which has guiding significance for the design of brown rice processing device.
