针对传统的单吸风米糠和碎米分离装置存在分离效率低、风速要求较大等问题，设计了一种对称式结构双吸风的新型米糠和碎米分离装置。采用Fluent-EDEM软件耦合的方法，在不同的吸风速度下对米糠和碎米混合物进行仿真分析，通过台架试验来检验新型分离装置的分离效果，并利用PIVlab观测分离装置中米糠颗粒的运动特征与仿真结果进行对比。结果表明：在吸风风速为4.5 m/s时，米糠和碎米的分离效果最为理想，装置内部形成明显的“X”型高速分离流场，中心区域最大上升气流速度为5.6 m/s,米糠最大上升速度为3.3 m/s。试验得出平均分离率为98.99%,损失率为0,利用PIV技术测得米糠的最大上升速度为3 m/s。...
