摘要 采取均匀设计试验,运用二次多项式逐步回归方法,建立卷烟主流烟气中氨释放量与制丝工艺参数的数学模型,并对模型进行主效应分析、单因素效应分析、双因素交互作用分析、边际效应分析。结果表明:工艺参数对卷烟主流烟气中NH3释放量影响大小依次为热风风门开度、HT工作蒸汽压力、筒壁温度、热风温度、筒体转速、切丝宽度,切丝宽度对NH3释放量影响不显著,NH3释放量与HT工作蒸汽压力和筒壁温度呈负相关,与热风风门开度、热风温度和筒体转速呈正相关,HT蒸汽工作压力和热风温度、HT工作蒸汽压力和筒壁温度,存在较强的交互作用。综合分析,降低热风风门开度、热风温度和筒体转速,提高HT工作蒸汽压力、筒壁温度,对控制卷烟主流烟气中NH3的释放有积极作用。 A mathematical model for spinning processing parameters and NH3 emission is established using uniform design and quadratic polynomial regression. And principal-factor effect, single-factor effect, marginal effect and double-factor effect of the model were analyzed. The result showed according to the contribution rate, NH3 emission in cigarette mainstream smoke was most greatly effected by open degree of the door of the hot air, followed by HT operating steam pressure, the temperature of cylinder wall, hot-air temperature, the revolving speed of casing cylinder and tobacco cut width, among which tobacco width was not significantly effected. The NH3 emission exhibit a negative correlation with HT operating steam pressure and the temperature of cylinder wall, whereas a positive correlation with hot air damper opening, hot-air temperature and the revolving speed of casing cylinder. Strong interactive influence existed between HT operating steam pressure and hot-air temperature, between HT operating steam pressure and the temperature of cylinder wall. Reducing the hot air damper opening, air temperature, or improving HT operating steam pressure, the temperature of cylinder wall will help to control the NH3 emission in mainstream cigarette smoke.
