核桃破壳后各级物料悬浮速度的试验研究

Experimental Study on Suspension Velocity of Different Materials After Walnut Shell Breaking

核桃破壳后各级物料悬浮速度是其空气动力学特性之一,是气力分离、挑拣装置设计的重要参考数据。核桃经破壳、混合物料分级、手工分离混合物料等工序,利用陕西省农业机械研究所自制的物料悬浮速度测试台针对分别测出嵌合体、1/2混合物、1/4混合物、1/8混合物、1/16混合物及碎末的壳、仁悬浮速度,可以为各级混合物料分离的气流参数提供试验和理论依据。

The suspension speed of all levels of materials after walnut shell breaking is one of its aerodynamic characteristics,which is an important reference data for the design of pneumatic separation and sorting device.The suspension velocity of chimera,1/2,1/4,1/8,1/16 and crushed walnut shells and kernels were measured by using the material suspension velocity test-bed made by Shaanxi Institution of Agricultural Mechanism,which can provide experimental and theoretical basis for air flow parameters of mixture separation at all levels.
