摘要
提出了双滚筒气力循环式花生脱壳机总体结构方案、二次循环脱壳与气力输送工作原理,进行了双滚筒脱壳装置、清选装置和传动系统等关键工作部件的结构设计。双滚筒脱壳装置由直径、转速不同的一次脱壳滚筒和二次脱壳滚筒以及各自的凹板筛构成;清选装置主要由振动筛和风机组成。花生脱壳试验结果表明:适宜含水率下花育23品种花生,在一次脱壳滚筒和二次脱壳滚筒转速分别为296、392 r/min时,花生脱壳综合性能指标最优,即花生脱净率为99.12%,花生仁破碎率为1.82%,花生仁损失率为0.40%。
The overall structure,work process and technical characteristics of the developed double-roller pneumatic circulating peanut sheller were summarized and the key work parts of the shelling device of double-roller,the cleaning device and the transmission system were designed.The double-roller shelling device was composed of primary shelling roller with different diameters and speeds,secondary shelling roller and each concave screen.The cleaning device was mainly composed of vibrating screen and air blower.Tests results of peanut shelling showed that the comprehensive performance indexes were： 1.82% for damaged peanut,99.12% for the net rate of removal and 0.40% for the loss rate of peanut when the experiment was carried on the variety of peanut Huayu 23 with moisture content,and 296 r/min for the speed of first peanut sheller and 392 r/min for the second peanut sheller.
