摘　　要：为了提高稻谷在干燥过程时搅拌的均匀性,基于离散元法,运用EDEM仿真模拟软件,对稻谷颗粒在不同转速、填充率等关键参数条件下进行分析,进而得到滚筒搅拌均匀性的最佳工作参数。通过单因素仿真试验求得离散系数,来比较不同参数下滚筒的搅拌效果,结果表明:滚筒最佳工作参数为转速55 r/min、填充率10%,此时稻谷含水率均匀性达到99%,作业效果满足要求。In order to improve the uniformity of rice stirring during the drying process,based on the discrete element method and EDEM simulation software,the rice particles were analyzed under different key parameters such as rotational speed and filling rate,and the optimal working parameters for drum stirring uniformity were obtained.Through single factor simulation test results,the discrete coefficient was obtained to compare the mixing effect of the drum under different parameters.The results showed that the optimal working parameter for the drum was when the speed was 55 r/min and the filling rate was 10%.After the experiment,the uniformity of water content reached 99%,and the operating effect met the requirements.
