2004和2007年国产不同价类卷烟配方烟丝结构的比较

摘要

利用平面旋转偏心式检测筛检测了2004和2007年国产不同价类共计25个牌号(规格)卷烟烟支中的配方烟丝结构,并比较了2004和2007年国产不同价类卷烟配方烟丝结构的差异.结果表明:①2007年国产不同价类卷烟的配方烟丝中大于3.35 mm的配方烟丝较2004年基本呈现减少的趋势.②相比2004年不同价类卷烟,2007年二类、三类和四类卷烟不同尺寸段烟丝比例的标准偏差减小.而一类与五类卷烟不同尺寸段烟丝比例的标准偏差增加.③相同价类、不同牌号卷烟配方烟丝中大于7.10mm的烟丝相比其他尺寸段配方烟丝比例的标准偏差偏大.%The size distribution of cut fillers in 25 domestic cigarette brands of different price categories produced in 2004 and 2007 were determined with a horizontally rotary eccentric sieve and compared.The results showed that: 1 ) The proportion of cut tobacco longer than 3.35 mm in cigarettes produced in 2004 was higher than that in cigarettes produced in 2007; 2 ) Comparing with cigarettes produced in 2004, the standard deviation of different size proportion in samples of Categories Ⅱ , Ⅲ and Ⅳ reduced in 2007; while that of Categories I and V increased; 3) Comparing with other size proportions, the standard deviation of cut tobacco 7.10 mm and over in length in the same category was the highest.
