摘　　要：为提高滚筒烘丝机叶丝干燥加工质量,采用稳健设计法研究热风温度、热风风速、筒壁温度和负压等因素对烟丝加工后叶丝含水率和温度的影响。结果表明:热风温度、热风风速、筒壁温度和负压等因素对干燥后叶丝含水率和温度均值和波动均有一定影响;稳健设计对影响工艺参数进行了优化,各因素的最佳组合为热风温度105℃、热风风速0.17m/s、筒壁温度135℃、负压-30Pa。在此条件下,干燥后叶丝稳定性达最优。In order to improve the drying quality of drum dryer,the effects of hot air temperature,hot air velocity,cylinder wall temperature and negative pressure on the moisture content and temperature of cut tobacco after processing were studied by using the robust design method.Results:Hot air temperature,hot air velocity,cylinder wall temperature and negative pressure have some effects on moisture content,temperature average value and fluctuation after drying,and robust design optimizes the process parameters.The optimum combination of these factors is hot air temperature 105℃,hot air velocity 0.17 m/s,cylinder wall temperature 135℃and negative pressure-30 Pa.Under these conditions,the stability of the dried cut tobacco is the best.
