摘　　要：为研究不同地区烟梗的吸湿性能,对吸湿性能相近的样品进行分组,实验室模拟制梗丝线加工过程,采用单因素试验法研究洗梗水温和洗梗时间对不同地区烟梗含水率增量的影响,并对试验结果进行聚类分析,根据聚类分析结果对烟梗实施分组并进行实际生产验证。结果表明:①洗梗水温、地区及两者交互作用对烟梗贮后含水率增量的影响均为极显著。洗梗时间、地区及两者交互作用对烟梗贮后含水率增量的影响均为极显著。不同地区烟梗同一参数加工时,含水率增量差异较大,说明混合加工不利于控制含水率稳定性。②根据聚类分析结果并结合生产实际情况,可将6地区烟梗分为三组,其中湖南梗单独为一组,云南和河南梗为一组,福建、重庆和贵州梗为一组;③生产线验证结果表明,原配方梗混合加工贮后含水率标准偏差达到1.15%,分组加工后组内标准偏差均低于0.35%,组内烟梗的水分均匀性得到提高。In order to study the moisture absorption of tobacco stems from different areas and group tobacco stems according to their moisture absorption, the cut tobacco stem processing was simulated in laboratory. The effects of dipping temperature and time on the increase of moisture content in stems from different areas were investigated with single factor test, and the cluster analysis of experimental data were conducted. Tobacco stems were grouped and processed on an actual production line for validation. The results showed that： 1） Stem dipping temperature, producing areas and their interaction extremely significantly affected the increase of moisture content in stems, as did dipping time, producing areas and their interactions. At the same processing parameters, the increase of moisture content in stems from different areas differed greatly, which indicated that mixing stems from different areas for processing was not beneficial to the consistance of moisture content in stems. 2） According to the results of cluster analysis, it was recommended to divide tobacco stems from 6 areas into 3 groups, namely Group 1 （Hunan stems）, Group 2 （Yunnan and Henan stems） and Group 3 （Fujian, Chongqing and Guizhou stems）. 3） The standard deviation of moisture content in stems by original grouping means was 1.15% after storing, while it was less than 0.35% when the stem was grouped and processed according to the recommended method.
