Effects of HXD pneumatic drying on cigarette comprehensive quality

The effect of HXD pneumatic drying, CO₂ expansion and different HXD expanded cut tobacco blending ratios on cigarette comprehensive quality was studied. The results showed that expanded cut tobacco with HXD pneumatic drying could increase whole cut rate and reduce small stands rate of the blends, cut tobacco structure and elasticity were better; In the test brands, sensory quality of cigarette with HXD expanded cut tobacco was better when blending ratios were the same; the optimum blending ratio of HXD expanded cut tobacco was 15%.
