摘要
为了将叶梗分离后的叶片结构指标控制在适宜范围,满足卷烟原料质量稳定性的要求,对打叶机一级、二级打叶器的框栏进行组合设计,其中一级打叶器选用不同尺寸的六边形框栏和菱形框栏的组合,二级打叶器选用3.0英寸六边形框栏和2种尺寸菱形框栏的组合设计。研究不同框栏形状、大小对叶片结构指标及片形的影响。结果表明一打使用3.5英寸的六边形框栏和3.25英寸菱形框栏的组合设计,二打使用2.25英寸的菱形框栏进行打叶,叶片结构指标改善明显,叶梗分离后的大片率可控制在45%以下,中片率可控制在40%以上,叶中含梗率控制在1.2%以内,片烟形状更加趋于规则,能够满足卷烟生产对卷烟原料叶片结构的新要求。研究成果可为烟草企业的打叶复烤工艺优化提供参考。
In order to control the leaf structure index after the stem separation in an appropriate range to meet the requirements of the quality stability of cigarette raw materials,the combination design of the frame basket of the first and second-stage threshers,the combination of hexagonal and rhombic frame baskets of different sizes was selected for the first-stage thresher,the combined design of 3.0-inch hexagonal frame basket and two kinds of rhombic frame baskets was selected for the second-stage thresher,and the influence of different frame shapes and sizes on leaf blade structure index and shape was studied.The results show that the combination design of 3.5-inch hexagon frame basket and 3.25-inch rhombic frame basket was used in the first-stage thresher,and the 2.25-inch rhombic frame basket was used in the second-stage thresher.The index of leaf structure is improved significantly and the percentage of large-sized strips can be controlled below 45%,the medium-sized strips percentage was controlled above 40%,the stem percentage in leaves was controlled within 1.2%,and the shape of tobacco leaves tends to be more regular,which can meet the new requirements of the leaf structure of cigarette raw materials in tobacco industry.The research results can provide a reference for tobacco enterprises to optimize the threshing and redrying process.
