摘　　要：针对当前工业企业对烟叶叶片结构需求的变化,设计在打叶风分汇总后增加叶片筛分复打设备,并对设备工艺参数进行优化,从而实现叶片结构降低大片率、提高中片率及优化叶形的目的。以中烟100为材料,采用L9(34)正交试验设计,研究了框栏形状、筛选辊转速和打辊转速3个因素对烟叶叶片结构的影响。结果表明,打叶风分后应用叶片筛分复打工艺能显著改善叶片结构比例,调控烟叶片形结构的最优参数为六边形框栏、80 r/min的筛选辊转速、650 r/min打辊转速。采用最优工艺参数叶片大片所占比例降低了10.70个百分点,中片所占比例提升了8.57个百分点,最佳烟叶片形比例提升了12.64个百分点。同时,烟片片形趋于方圆,提高了片烟原料制丝后的利用率。Aiming at the demand change of tobacco industrial enterprises for tobacco leaf stalk shaped structure,after the increase of blade screen rebeating equipments behind the belt of threshing and pneumatic separation,as well as the optimization of technological parameters of the equipment,the purpose of reducing the large and increasing the medium shape of tobacco leaf structure and improving the leaf shape is realized.Taking Zhongyan 100 as the material and using the orthogonal experiment design of L9(34),the influence of three factors on the tobacco blade structure,such as frame column shape,screening roll speed and roll speed,is studied.The results show that the application of tobacco leaf screening and rebeating process can significantly improve the proportion of tobacco leaf structure after threshing and pneumatic separation.The optimal parameters for regulating tobacco leaf shape structure are hexagonal frame bar,screening roll speed of 80 r/min and roll speed of 650 r/min.By using the optimal technological parameters,the large shape of tobacco leaf decreases by 10.70 percentage points,the medium shape of tobacco leaf increases by 8.57 percentage points,and the best proportion of tobacco leaf shape increases by 12.64 percentage points.At the same time,the leaf shape tends to be circumferential,which improves the utilization rate for the silk of tobacco blade raw material.
