摘　　要：[目的]研究制丝过程二次回潮加料、加料工序补水的控制模式对制叶丝切叶丝含水率控制稳定性的影响,为该控制模式在制丝线的应用提供数据支撑。[方法]通过对比制丝过程中2种切叶丝含水率的控制模式,用过程能力指数Cpk评价切叶丝含水率的稳定性及精准控制水平,分析不同控制模式对下游烘丝工序稳定性、精准控制水平以及卷烟感官品质的影响。[结果]采用两级加料合并为二次回潮加料并通过加料工序出料水分自动闭环控制补水来满足切叶丝含水率工艺需求的控制模式,可有效提高切叶丝含水率Cpk和烘丝工序筒壁温度Cp。采用新控制模式的试验样品与大生产样品香气风格特征无明显差异,试验样品的香气清晰度、烟气润感、细腻度好于大生产样品。[结论]加料工序补水的控制模式可以有效提升制丝过程中切叶丝含水率的精准控制水平,且有助于提升后续工序稳定性控制水平。[Objective]To investigate the influences of the control mode of twice moisture recharging and feeding moisture recharging in the cutting process on the control stability of water content in tobacco leaf,and provide data supports for the application of this control mode in the tobacco leaf-making line.[Method]By comparing two control modes of water content in the tobacco leaf-making process,the stability and precision control level of water content in tobacco leaves were evaluated by using process capability index Cpk,and the effects of different control modes on the stability,precision control level of downstream tobacco leaf-drying process,and the sensory quality of cigarettes were studied.[Result]The water content Cpk of the tobacco leaf-cutting and cylinder wall temperature Cp of silk-drying process could be effectively increased by using the control mode of combining two stages of feeding into a primary moisture recovery feeding and automatic closed loop control of water refill through the secondary moisture recovery process.There was no significant difference in aroma style characteristics between the test samples in new control mode and large production samples.The test samples were better than large production samples in terms of aroma clarity,smoke moistening,and smoothness.[Conclusion]The control mode of water replenishment in the feeding process can effectively improve the precision control level of water content of the tobacco leaf in the filament-making process.And it can help to improve the stability control level of the subsequent processes.
