摘 要：
采用SPSS统计分析软件,回归分析了滚筒烘丝机"干头干尾"过程工艺参数对烟丝含水率的影响。结果表明:(1)"干头"烟丝含水率回归方程:Y=8.265+0.716X1+0.730X2+0.686X3+0.710X4-0.699X5;"干尾"烟丝含水率回归方程:Y=9.347+0.924X1+0.823X2-0.929X3,"干头"烟丝含水率与样品烟丝含水率、蒸汽流量、I区、II区筒壁温度、热风温度相关系数分别为:0.945,0.944,0.862,0.895,-0.928;"干尾"烟丝含水率与I区、II区筒壁温度、热风温度的相关系数分别为:0.859,0.757,-0.897。(2)"干头"烟丝含水率主要受蒸汽流量影响,"干尾"烟丝含水率主要受热风温度影响。(3)采用上述结果对HAUNI 6 000 kg/h烘丝机进行优化改进试验,"干头干尾"烟丝量降低了38.7%。可见,通过建立滚筒烘丝机"干头干尾"过程相关工艺参数对烟丝含水率影响的数学模型,可以为有效控制烘丝过程中"干头干尾"烟丝量、提高生产过程控制精度及烘丝工艺参数优化提供理论支撑。

摘 要：
The related process parameters which affect the moisture content of cut tobacco during the over-drying process had been regression analyzed by SPSS statistical analysis software. The results showed that:( 1) The regression equation during drying start was Y = 8. 265 + 0. 716X1+ 0. 730X2+0. 686X3+ 0. 710X4- 0. 699X5; The regression equation during drying end was Y = 9. 347 +0. 924X1+ 0. 823X2- 0. 929X3. The correlation coefficients between the moisture content of over dried cut tobacco during drying start and moisture content of feeding cut tobacco,the steam flow rate,cylinder wall temperature of I section and II section,the hot air temperature were 0. 945,0. 944,0. 862,0. 895 and- 0. 906. The correlation coefficients between the moisture content of over dried cut tobacco during drying end and the steam flow rate,cylinder wall temperature of I section and II section were0. 859,0. 757 and- 0. 897.( 2) The moisture content of over dried cut tobacco during drying start was mainly affected by hot air temperature. The moisture content of over dried cut tobacco during drying finish was mainly affected by the steam flow.( 3) Optimizing and improving HAUNI 6 000 kg / h drying test,the amount of over-drying cut tobacco was reduced by 38. 7%. The mathematical model that the related process parameters affect the moisture content of over dried tobacco can effectively control the amount of over-drying cut tobacco,improve the production process control precision and optimize drying process.
