摘要
为了确定制丝工艺对主流烟气中巴豆醛释放量的影响,通过均匀设计法,建立了切丝宽度、HT工作蒸气压力、热风温度、热风风门开度、筒壁温度、筒体转速6种制丝工艺参数与卷烟主流烟气巴豆醛释放量的二次多项式逐步回归模型,并对模型进行了因素主效应分析、单因素效应分析、边际效应分析和双因素交互作用分析。结果表明,6种工艺参数对巴豆醛释放量的贡献率由大到小依次为筒壁温度、热风风门开度、切丝宽度、热风温度、筒体转速、HT工作蒸气压力。切丝宽度、HT工作蒸气压力、热风温度、热风风门开度的增加会促进巴豆醛的释放,筒体转速和筒壁温度的升高会抑制巴豆醛的释放;切丝宽度、HT工作蒸气压力、热风温度、筒壁温度和筒体转速对巴豆醛释放量的影响随其他工艺参数水平的升高而增大,热风风门开度的影响不变。切丝宽度与HT工作蒸气压力、切丝宽度与热风温度、筒壁温度与筒体转速之间存在交互作用影响巴豆醛释放量。
A mathematical model was established by regression techniques from the six processing parameters including tobacco cut width,HT operating steam pressure,hot-air temperature,hot air damper opening,the temperature of cylinder wall,and the revolving speed of casing cylinder to the emission of crotonaldehyde in mainstream smoke.The principal-factor effect,single-factor effect,marginal effect and double-factor effect of the model were analyzed.The results showed that the contribu tion order for the crotonaldehyde emission was the temperature of cylinder wall＞hot air damper opening＞tobacco cut width＞hot-air temperature＞the revolving speed of casing cylinder＞HT operating steam pressure.The crotonaldehyde release amount increased with tobacco cut width,HT operating steam pressure,hot-air temperature and hot air damper opening,and decreased with the temperature of cylinder wall.The revolving speed of casing cylinder promoted the crotonaldehyde delivery under low level background,and inhibited it under middle and high level background.The influence of tobacco cut width,HT operating steam pressure,hot-air temperature,temperature of cylinder wall and the revolving speed of casing cylinder on crotonaldehyde emission aggravated with the increasing of other parameters.Hot air damper opening＇s effect didn＇t change.In addition,interactive influence on crotonaldehyde delivery existed between tobacco cut width and HT operating steam pressure,tobacco cut width and the temperature of cylinder wall,the temperature of cylinder wall and the revolving speed of casing cylinder.
