摘　　要：揉搓型油茶果分类脱壳分选机采用揉搓和挤压原理,通过利用分类滚动筛筛选大小不同的油茶果进入油茶果脱壳装置,在运输带与柔性揉搓板相互配合运动的揉搓作用下而脱壳。结果表明：在含水率低于55%,曲轴转速在240~260 r/min,履带速度在0.4~0.6 m/s,振动电动机频率50 Hz,分选带水平面倾角50°~55°工艺条件下,该机处理量≥900 kg/h,脱净率≥97%,清选率≥97%,碎籽率≤5%,损耗率≤1%。此设备在实际生产中具有普适性,适合大规模推广应用。Camellia oleifera fruit sheller in this paper was designed by the principle of rubbing and extruding. This machine adopted the rolling classification sieve to screen C. oleifera fruit with different sizes into the husking device,and C. oleifera fruit was shelled in the mutually co-operative action of transport belt and flexible rubbing washboard. The result showed that,in the condition that the moisture content of C. oleifera fruit was below 55%,the speed of crankshaft was240 ~ 260 r / min,track speed was 0. 4 ~ 0. 6 m / s,the vibration of the motor frequency was 50 Hz and the horizontal angle of sorting belt was 50 to ~ 55 degrees,the processing capacity was more than or equal to 900 kg / h,the threshing ratio was more than or equal to 97%,the seed broken ratio was less than or equal to 5% and the loss ratio was less than or equal to 1%. The machine is of great value in actual production,and should be widely spread and applied.
