Relationship between Processing Parameters of COMAS Drier and Quality of Cut Lamina

In order to increase the expansion ratio of cut lamina dried by COMAS drier, processing parameters influencing the expansion ratio were tested. The result showed that 1) the filling value of the cut lamina was affected by its width, the optimal width was 0.95mm for premium cigarettes and 1.20mm for economic ones; 2) the filling value of the cut lamina was increased with the increase of the moisture content of cased lamina and the temperature of cut lamina while entering the drier; 3) the filling value of the cut lamina was increased with the increase of its flow rate within the capability of drier; and 4) for cut lamina with defined moisture content and temperature before drying, its quality could be improved by higher wall temperature combined with right temperature and flow rate of hot air inside the drier.
