摘  要:
为合理设计花生气力分选和二次脱壳气力输送装置,以辽宁主栽花生品种为研究对象,进行了花生脱壳机脱出物主要成分以及杂质等空气动力特性试验,得到了破损花生荚果、未脱净而需要二次脱壳的花生荚果、花生米、花生壳、石头的漂浮系数分别为0.168~0.246、0.102~0.146、0.080~0.186、3.287~6.037、0.031~0.045m-1。结果表明,花生荚果、破损花生荚果、花生米、花生壳和石头之间的漂浮速度的差异较大,有利于气力分选,可作为花生脱壳机分选装置和气力输送装置设计的重要参考依据。

摘  要:
In order to design pneumatic classifier and pneumatic conveying equipment of peanut sheller,based on main peanut varieties which were planted in Liaoning province as the research object,aerodynamic characteristics of shelled peanut mixtures were tested and floating coefficients of broken peanut pod,no-shelled and smaller peanut pod,peanut kernel,peanut shells and small stone were separately gotten for 0.168-0.246、0.102-0.146、0.080-0.186、3.287-6.037、0.031-0.045 m-1.The results showed that:the floating speeds of broken peanut pod,no-shelled and smaller peanut pod,peanut kernel,peanut shells and small stone were obviously different and more suitable for air separation.The test conclusion has important significant for improvement of pneumatic classifier and pneumatic conveying equipment of peanut sheller.
