制丝工艺参数对9种主流烟气成分释放量的影响

Effects of Five Primary Processing Parameters on Deliveries of Nine Components in Mainstream Cigarette Smoke

研究了5个主要制丝工艺参数(松散回潮热风温度A、切丝宽度B、HT工作蒸汽流量C、烘丝热风温度D和排潮风门开度E)对9种主流烟气成分(焦油、烟碱、CO、NH3、HCN、苯酚、巴豆醛、B[a]P和NNK)释放量的影响;采用D-优化、A-优化和Ⅳ-优化方法并结合平衡设计原理进行了五因素三水平实验设计,并对实验结果进行了直观分析、方差分析和多重比较。结果表明:15种工艺参数均对NH3和HCN有影响,大小顺序为:B>D>C>E>A;24种工艺参数对B[a]P有影响,顺序为:A>D>B>E;34种工艺参数对NNK有影响,顺序为:E>A>B>C;44种工艺参数对烟碱有影响,顺序为:B>A>E>D;52种工艺参数对苯酚、焦油和CO有影响,顺序为:B>A;62种工艺参数对巴豆醛有影响,顺序为:E>D。

The effects of five primary processing parameters （A：hot air temperature in ordering cylinder,B：cut width of tobacco,C：steam flow rate in HT,D：hot air temperature in dryer,and E：exhaust vane opening in dryer） on the deliveries of tar,nicotine,CO,NH3,HCN,phenol,crotonaldehyde,B[a]P and NNK in mainstream cigarette smoke were investigated.An experiment of five-factor and three-level was designed by combining D-optimum design,A-optimum design and Ⅳ-optimum design with balance design principle,and the results of the experiment were analyzed by visual analysis,ANOVA and multiple comparison.The results showed that：1） All of the five parameters affected the deliveries of NH3 and HCN in the order of B＞D＞C＞E＞A; 2） Parameters A,B,D and E affected B[a]P delivery in the order of A＞D＞B＞E; 3） Parameters A,B,C and E affected NNK delivery in the order of E＞A＞B＞C; 4） Parameters A,B,D and E affected nicotine delivery in the order of B＞A＞ E＞D; 5） Parameters A and B affected the deliveries of phenol,tar and CO in the order of B＞A; 6） Parameters D and E affected crotonaldehyde delivery in the order of E＞D.
