Abstract:

To determine the leaf-making techniques for fine cigarettes, the structures of rhombic and hexagonal framed sheets were compared from three aspects of leaf quality, leaf shredding quality and cigarette quality. The results show that: (1) hexagonal framed sheets have the advantages of relatively uniform size, good water content and filament stability, and uniform distribution of cigarette density, but the disadvantages are weak fragmentation resistance, whole filament rate and tobacco quality; the utilization ratio of cut tobacco is low, but those characteristics of rhombic frame sheets are the opposite.; (2) compared with rhombic frame cigarettes, hexagon frame cigarettes have better stability of single cigarette weight, cigarette resistance, total particles and tar, better combustion fly ash and holding ability, shorter combustion time and less number of suction ports, no obvious change of filar filling value and other physical smoke indicators after cigarette processing. Therefore, from the intrinsic quality of cigarettes, it is more appropriate to select the cigarettes processed by hexagon frame column for the fine cigarettes.
