不添加料液的混合型膨胀烟丝生产工艺及质量分析

  目的  研究白肋烟不添加料液、不进行烘焙处理的生产模式对混合型膨胀烟丝综合质量的影响。  方法  设计了不加料、不烘焙白肋烟烟片处理线的混合型膨胀烟丝生产工艺流程，同时，研究了切片、松散回潮工序白肋烟和烤烟烟片分组加工技术，并对膨胀工序热风温度进行了优化设置。  结果  经对比，白肋烟不添加料液、不烘焙处理的混合型膨胀烟丝较传统工艺路径处理的混合型膨胀烟丝的质量指标有以下变化:（1）膨胀烟丝的结构变化不显著、填充值显著升高。（2）总糖含量显著降低，总烟碱、总氮、总挥发碱、总氯含量显著升高，总钾含量变化不显著。（3）烟气烟碱、焦油、一氧化碳量显著降低；HCN、NNK、Ba]P、苯酚、巴豆醛等释放量以及卷烟危害评价指数均不同程度降低。  结论  与传统工艺路径处理的混合型膨胀烟丝相比，白肋烟不添加料液、不进行烘焙处理的混合型膨胀烟丝不会对卷烟感官品质造成不利影响，降焦减害效果则更加明显，且能大大简化工艺流程、提高生产效率、降低生产成本。 

Processing and quality analysis of blended type expanded tobacco dispensed with sauce applying

Objective]To study effects of production mode of burley tobacco dispensed with sauce applying and baking treatment on comprehensive quality of blended expanded cut tobacco.Method]Designed the production process of blended type expanded cut tobacco without adding or baking burley tobacco sheet processing line.At the same time,the grouping processing technology of burley and flue-cured tobacco sheet in the sectioning and loose resurgence process was studied.The hot air temperature has been optimized.Results]Comparing with the traditional process route,the blended type expanded cut tobacco with no added liquid and no baking treatment has the following changes:(1)the structure of the expanded cut tobacco was not significantly changed,The fill value increases significantly.(2)total sugar content decreased significantly,the contents of total nicotine,nitrogen,volatile nicotine and chlorine increased significantly,while total potassium content remained unchanged.(3)the contents of nicotine,tar and CO in cigarette smoke decreased significantly,the content of hydrocyanic acid,NNK,Ba]P,phenol,crotonaldehyde and the hazard index of cigarette smoke decreased at different levels.Conclusion]Compared with the blended type expanded cut tobacco processed by the traditional process path,the expanded cut tobacco dispensed with sauce applying and baking treatment will not adversely affect the sensory quality of cigarettes,and the effect of reducing coke and harm will be more Obviously,and can greatly simplify the process flow,improve production efficiency,and reduce production costs.
