摘要
为研究卷烟制丝重点工序工艺参数对主流烟气焦油、一氧化碳及自由基释放量的影响,选择松散回潮、HT+烘丝两个工序分别进行均匀设计试验。结果表明:两个工序工艺参数对一氧化碳释放量的影响不显著;松散回潮工序的水汽喷嘴压力和热风温度的交互作用、HT+烘丝工序的HT工作蒸汽压力和筒体转速的交互作用对焦油释放量有正作用;HT+烘丝工序的热风温度、筒体转速对固相自由基释放量有正作用,HT工作蒸汽压力和热风温度的交互作用、排潮风门开度和热风风门开度的交互作用对固相自由基释放量有负作用;HT+烘丝工序的HT工作蒸汽压力、热风风门开度和筒体转速的交互作用对气相自由基释放量有正作用,筒体转速、热风温度和排潮风门开度的交互作用对气相自由基释放量有负作用。
In order to explore effects of key processes＇ parameters in the primary processing of cigarette production on releasing amounts of tar,carbon monoxide and free radical in cigarette mainstream smoke,both process of loosening and conditioning and process of HT and tobacco drying are selected to conduct uniform design experimentation.The results showed that both processes＇ parameters in the primary processing of cigarette production had little effects on releasing amount of carbon monoxide;the interaction between moisture vapor nozzle pressure and hot-blast temperature in process of loosening and conditioning and the interaction between HT operating vapor pressure and cylinder rotation speed in process of HT and tobacco drying had positive effect on releasing amount of tar;the hot-blast temperature and the cylinder rotation speed in the process of HT and tobacco drying had positive effect on releasing amount of particulatephase free radicals,but the interaction between HT operating vapor pressure and hot-blast temperature and the interaction between hot-blast air damper opening and moisture exhaust damper opening had negative effect on that;the interaction among HT operating vapor pressure,hot-blast air damper opening and cylinder rotation speed in process of HT and tobacco drying had positive effect on releasing amount of gaseous-phase free radicals,but the interaction among cylinder rotation speed,hot-blast air temperature and moisture exhaust damper opening had negative effect on that.
