摘　　要：对银杏核的结构尺寸、压缩破坏载荷及临界压缩变形量、密度等物性参数的测定表明 :银杏核分级时以级差 1mm、分级数以 4级为宜 ;破壳机的挤压腔间隙至少应保证 2 .4 4～ 3.11mm的变形量 ,以使破壳率和碎仁率能满足生产要求 ;银杏核、仁和壳的密度有一定差异 ,用重力式清选机分离是可行的。The experimental study on physical parameters of gingko is conducted.The structural size,compressive crushing load,critical compression and density of gingko core are measured.The tests showed that the gingko core could be classified into 4 grades by step of 1 mm.The size of extrusion space should be adjusted so that the gihgko core could have 2.44～3.11 mm deformation in order to obtain a satisfying shell-broken rate and kernel-unbroken rate.The gingko core,shell and kernel could be separated by specific gravity separator according to the different density.
