摘要
为了进一步寻求打叶复烤过程中配方均匀性的调控方法,在调控烟碱的基础上,引入了烟叶颜色定性值和光谱定性值2个新的调控因子,采用基于配方高架库的单一或组合因子调控方法,分析了不同调控模式下打叶复烤的均质化效果。结果表明:①各调控模式均可将配方模块的成品片烟烟碱变异系数控制在3%以下;②不同调控模式对于成品片烟化学成分整体均匀性调控能力排序为:光谱调控>烟碱+颜色调控>颜色调控>烟碱调控>光谱+颜色调控,对于成品片烟近红外光谱均匀性调控能力排序为:光谱调控≈烟碱+颜色调控>颜色调控>烟碱调控>光谱+颜色调控;③光谱离散度和光谱相似度与化学成分整体均匀性K值有较显著的相关性,相关系数分别为0.85和0.96。
To promote consistency of blended tobacco during tobacco threshing and redrying,two new control factors,namely the color qualitative value and spectral qualitative value,of tobacco leaves were introduced to regulate nicotine contents.The consistency of tobacco threshing and redrying under the different regulation modes was compared based on a typical high-bay warehouse setup.The results showed that:1)The coefficient of variation(CV)of nicotine in the finished blend strips was all below 3%under the tested modes.2)The regulation modes in the order of regulation ability for chemical component consistency of finished strips were spectrum regulation>nicotine+color regulation>color regulation>nicotine regulation>spectrum+color regulation.The control ability for the near-infrared spectral consistency of the finished strips were in the order of:spectrum regulation≈nicotine+color regulation>color regulation>nicotine regulation>spectrum+color regulation.3)Spectral dispersion and similarity significantly correlated to the chemical component consistency,K value,with the correlation coefficients of 0.85 and 0.96 respectively.
