摘要: 为了解决榛子脱苞后筛分效率低的问题，针对榛子脱苞后的物料状态设计了一种双层滚筒筛。运用EDEM仿真软件对其工作状态进行模拟，以滚筒转速、内外筛孔大小、螺旋叶片间距为试验因素，以筛分率和含杂率为评价指标，分析评估各因素对双层滚筒筛性能的影响，以获得双层滚筒筛的最佳工作参数。结果表明：当滚筒筛的内筛孔尺寸为25 mm、外筛孔尺寸为12 mm、转速为36 r/min、螺旋叶片间距为240 mm时，滚筒筛的筛分效率最佳。Abstract: In order to solve the problem of low sieving efficiency after hazelnut deflashing, a double-decker trommel screen was designed for the material state after hazelnut deflashing. The EDEM simulation software was used to simulate the working condition of the screen, and the drum speed, inner and outer screen hole size and spiral blade spacing were used as test factors, and the screening rate and impurity rate were used as evaluation indicators to analyse and assess the influence of each factor on the performance of the double-decker drum screen to obtain the best working parameters of the double-decker drum screen. The results show that the best screening efficiency is achieved when the inner screen hole size is 25 mm, the outer screen hole size is 12 mm, the rotational speed is 36 r/min and the spiral blade spacing is 240 mm.
