摘要
为优化双滚筒气力循环式花生脱壳机脱壳装置的有关参数,降低花生籽仁在脱壳过程中的损伤,提高脱壳质量和生产率,以籽仁破损率、脱净率和生产率为主要评价指标,以滚筒转速、喂入量和脱壳间隙为试验因素,采用L16(45)正交试验和综合评分法对双滚筒气力循环式花生脱壳机进行了性能试验。结果表明:对于‘花育23’花生品种,当一级脱壳滚筒和二级脱壳滚筒转速分别为300和375 r.min-1,喂入量为25 kg.min-1,脱壳间隙为20 mm时,脱壳机综合性能最优,其破损率为1.84%,脱净率为95.87%,生产率为885.25 kg.h-1。研究成果对进一步研究花生的脱壳原理、优化脱壳系统结构、提高花生脱壳工艺和产品质量具有重要的意义。
In order to optimize parameters of the shelling device of double-roller pneumatic circulating peanut sheller, reduce the me- chanical damage of peanut seeds, improve shelling quality and productivity in the course of shelling, an experiment of L16 （45） orthogonal with comprehensive scoring method was carried out with the rotating speed of roller, feeding quantity and shelling clearance as influence factors and the broken rate of kernel, shelling net rate and productivity as major evaluation index. The results showed that the comprehensive performance of double-roller pneumatic circulating peanut sheller reached optimal, with the broken rate of kernel being 1. 84% ,shelling net rate being 95.87% and the productivity being 885.25 kg.h-1 ,when the experiment was carried on the variety of peanut＇ Huayu 23＇ , and 300 r.min-1 for the speed of first shelling roller and 375 r- min-1 for the second shelling roller,25 kg. min-1 for the feed quantity, and 20 mm for the shelling clearance. This research has important meanings for future research on the mechanism of peanut sheller and the structure optimization of shelling system, and it also is useful for improving the shelling technology and the quality of peanut products.
