摘　　要：[目的]了解不同类别烟梗的吸湿性能。[方法]实验室模拟烟梗预处理工艺过程,对不同地区、部位、年份、尺寸的烟梗进行吸湿性能分析,并根据分析结果将吸湿性能相近的烟梗组合进行生产验证。[结果]不同地区烟梗吸湿性能存在差异,根据洗梗前后含水率增量分布情况,可将24个不同地区划分为3个组,形成不同的烟梗配方。中上部烟梗的吸湿性能相对接近,下部烟梗吸湿性能强于中上部。烟梗贮存年限越长,含水率增量越大。不同直径烟梗吸湿性能差异显著,粗梗的含水率增量明显低于细梗。生产验证结果表明,原配方烟梗的含水率标准偏差达到0.68%,出丝率为87.03%,新配方含水率标准偏差0.27%,出丝率为88.49%,烟梗的水分均匀性得到提高,过程工艺损耗减少。[结论]该研究可为烟梗的分组加工和配方设计提供一定的参考依据。[ Objective ] In order to understand the moisture absorption properties of different categories tobacco stems. [ Method ] The pretreat- ment process of tobacco stems was simulated by laboratory, moisture absorption performances of different areas, location, year, size of tobacco stems were analyzed, and according to the analysis results, the combination of tobacco stems with similar moisture absorption performance was verified by production. [ Result] The results showed that there are differences in moisture absorption performance of tobacco stems in different areas. According to the increment distribution of moisture content before and after the stem washing,24 different areas can be divided into 3 groups to form different tobacco stem formulas. Water absorption of the middle and upper tobacco stems was relatively close, and the moisture absorption of the lower stems was stronger than that of the middle and upper parts. The longer the storage life of tobacco stem, the greater the moisture content increment. The moisture absorption of tobacco stems with different diameters was significantly different, and the moisture content increment of rough stems was lower than that of fine stems. The production verification results showed that the standard deviation of water content of original formula tobacco stem reached 0.68% ,the cut yield was 87.03% and the standard deviation of moisture content of new formula tobacco stem was 0.27 %, the cut yield was 88.49%, the moisture uniformity of tobacco stems was improved, the loss in the process was reduced. [ Conclusion ] The study can provide a certain reference basis for processing and formula design of tobacco stems.
