In order to study the volatile and semivolatile components changes of cut tobacco in the drying process, the cut tobacco were determined by headspace-gas chromatography/mass spectrometry (HS-GC/MS). Principal component analysis (PCA) and similarity analysis were used to analyze the HS-GC/MS results. Based on the similarity, the drying conditions and drying mechanism have been studied. The results showed that the increase in water content would reduce the dying rate, and if the temperature increased, the dying rate increased. The preliminary study on the drying kinetics of the drying process shows that Henderson and Pabis model appeared to be the most suitable for describing the drying process of cut tobacco, and the drying activation energy is 111.9 kJ.

基于 HS-GC/MS 的烟丝干​​燥工艺研究：主成分分析、相似性分析、干燥条件和干燥机理

为研究烟丝在干燥过程中挥发性和半挥发性成分的变化，采用顶空-气相色谱/质谱法（HS-GC/MS）对烟丝进行了测定。使用主成分分析 (PCA) 和相似性分析来分析 HS-GC/MS 结果。基于相似性，对干燥条件和干燥机理进行了研究。结果表明，水含量的增加会降低死率，如果温度升高，死率会增加。干燥过程的干燥动力学初步研究表明，Henderson和Pabis模型似乎最适合描述烟丝的干燥过程，干燥活化能为111.9 kJ。
