摘要：采用正交试验极差分析的方法研究了滚筒干燥工艺参数（筒壁温度、切丝后含水率和HT（隧道式烟丝增温增湿装置）蒸汽压力）对烟丝填充值、烟丝结构和感官品质的影响，并对3个滚筒干燥工艺参数进行了优化.结果表明：对干燥后烟丝填充值影响的主次顺序为HT蒸汽压力>切丝后含水率>筒壁温度;对干燥后烟丝结构影响的主次顺序为HT蒸汽压力>筒壁温度>切丝后含水率;对干燥后烟丝感官品质影响的主次顺序为切丝后含水率>筒壁温度>HT蒸汽压力;HT蒸汽压力对烟丝填充值和整丝率的影响最大，对感官品质的影响最小;增大烟丝填充值的最优组合为切丝后含水率21.0%， HT蒸汽压力0.40 MPa，筒壁溫度140 ℃，在该最优组合下，烟丝填充值增大了0.21 cm3/g.

Abstract：The range analysis of orthogonal experiment method was used to study the effects of cylinder drying process parameters （drying temperature in cylinder，water content after cutting and HT （tunnel type tobacco temperature and humidification device） vapor pressure） on cut tobacco filling value，structure and sensory quality.And the three cylinder drying process parameters were optimized.The results showed that the importance ranking of key process parameters on filling value was established，which was HT vapor pressure > water content after cutting > drying temperature in cylinder.The individual degree of influence on structure of cut tobacco was ranked，which was HT vapor pressure > drying temperature in cylinder > water content after cutting.The influence degree that each factor works on sensory quality was sorted，which was water content after cutting > drying temperature in cylinder > HT vapor pressure.The effect of HT vapor pressure on filling value and structure of cut tobacco was the most significant，but on sensory quality was the least significant.In order to increase filling value and reduce the influence on sensory quality，the HT vapor pressure could be set on 0.40 MPa，the water content after cutting 21.0%，and the drying temperature in cylinder on 140 ℃.Under this optimal combination，the filling value of cut tobacco was increased by 0.21 cm3/g.

滚筒干燥是卷烟生产加工过程中的重要工艺流程，其工艺参数是影响烟丝物理指标和感官品质的重要因素[1]，对提升卷烟品质有重要作用.为了提升滚筒干燥过程中卷烟的各项物理指标和感官品质，行业内开展了很多相关研究[2-13].段鹍等[11]采用方差分析和多重比较的方法对烘丝机筒壁温度与烟丝填充值、烟丝弹性、整丝率、石油醚提取物等的相关性进行了分析，结果表明，烟丝填充值随烘丝机筒壁温度的升高呈增大的趋势，而烟丝弹性、整丝率、石油醚提取物、香味物质总量则随烘丝机筒壁温度的升高而减小.王岩等[12]分析了滚筒分段变温干燥方式下叶丝含水率、物……
