Influence of steam volume on expansion of cut tobacco dried in HXD and smoking quality of cigarette
Zhengzhou Tobacco Research Institute of CNTC, Zhengzhou, Henan, China
The influence of steam volume introduced in HXD system on the expansion effect of cut tobacco with different initial moisture contents and the smoking quality of cigarettes made of the same were studied. The results showed that the filling value of cut tobacco dried with relatively lower initial moisture content increased and the weight per cigarette decreased with the increase of steam volume introduced, while the expansion of cut tobacco with higher initial moisture content was not obviously influenced by the change of steam volume. For treating cut tobacco of premium or middle grade cigarette with low initial moisture content, it is appropriate to introduce no or a little steam into the HXD, however, for cut tobacco of economic grade cigarette with higher initial moisture content, adding more steam may be good for improving smoking quality.
