切丝宽度与烘丝方式对不同规格卷烟的影响

Effects of cut tobacco width and drying methods on cigarettes with different specifications

为研究切丝宽度、烘丝方式对不同规格卷烟烟支的物理质量、主流烟气常规指标和卷烟机台运行情况的影响规律,选取切丝宽度分别为0.8,0.9,1.0mm,烘丝方式分别为KLD滚筒干燥和HDT气流干燥的烟丝在中支、细支、短支卷烟规格上开展试验。对于同一规格的卷烟,烟支的圆周和重量保持不变。结果表明:①与滚筒烘丝相比,气流烘丝卷制的烟支吸阻升高,硬度增大,端部落丝减小;②与滚筒烘丝相比,气流烘丝卷制时的机台平整盘位置值增大,压实量减小;③随着切丝宽度的减小,烟支含末率升高,主流烟气中的CO量、焦油量、总粒相物、烟碱增加,中、细支卷烟空头率降低;④中、细支卷烟建议采用0.8,0.9mm较细的切丝宽度来解决烟支空头率较高的问题;⑤短支卷烟建议采用HDT气流烘丝的方式来解决端部落丝较大的问题。

In order to study the effects of cut tobacco width and drying methods for different cigarette sizes on cigarette physical characteristics,mainstream cigarette smoke and cigarette making machine operating conditions,tobacco with cutting width of 0.8,0.9,and 1.0 mm and drying methods of KLD and HDT were selected for experiments on middle,slim and short cigarette making machines.For the same size cigarettes,cigarette circumference and weight was instant.Results show that:①Compared to cylinder drying,for the pneumatic drying cigarettes,pressure drop was increased,hardness was increased,and content of loss of tobacco from the ends was decreased.②Compared to cylinder drying,trimmer disc position of cigarette making machine with pneumatic drying tobacco was increased,density amount was decreased.③With the cut tobacco width decreased,dust content of cigarettes was increased,mainstream cigarette smoke amount of CO,Tar,TPM and Nicotine was increased,and loose and rate of slim and middle cigarettes was decreased.④Cut tobacco width of 0.8 and 0.9 mm was recommended for slim and middle cigarettes to solve the problem of high loose and rate.⑤HDT pneumatic drying tobacco was recommended for short cigarettes to solve the problem of high content of loss of tobacco from the ends.
