叶中含梗率控制对打叶加工及卷烟生产的影响

Effects of Stem Content Control on Threshing and Cigarette Production

为指导烤烟打叶加工工作科学开展,构建适宜的叶中含梗率控制指标,通过调整打叶加工中叶中含梗率,研究叶中含梗率控制对打叶加工及卷烟生产的影响。结果表明,适度降低叶中含梗率(由1.5%降低到1.2%),能够维持烟叶的叶片结构处于适宜水平,满足后端卷烟生产的需要,能够有效保障原烟的经济效益;降低叶中含梗率后,能有效减缓烟支卷制环节的梗签剔除压力,降低卷制烟支中的梗签含量,提高烟支中的烟丝纯净度。同时,常规烟支在叶中含梗率控制在1.5%以内时,烟支中的刺破基本可控,而细支卷烟在叶中含梗率控制在1.2%以内,并结合卷包剔梗,烟支中的刺破亦基本可控。建议打叶复烤环节细支卷烟原料、高档卷烟原料的叶中含梗率控制在1.2%以下,其他卷烟原料控制在1.5%以下。

In order to guide the scientific development of the threshing process and construct the suitable controlling index of the stem content in the leaves,in this paper,the control index of the stem content in the middle leaves of the threshing process was adjusted,the effects of stem content control on beating and cigarette production were studied.The results showed that a moderate reduction of stem content(from 1.5%to 1.2%)could maintain the structure of tobacco leaves at an appropriate level and meet the needs of back-end cigarette production,after reduced the percentage of stem in the leaf,it can effectively slowed down the pressure of removing the stem tags,reduced the content of the stem tags and improve the purity of the cut tobacco.At the same time,when the percentage of stem in the leaves of conventional cigarettes was controlled within 1.5%,the puncturing rate in the cigarettes was basically controlled,while the percentage of stem in the leaves of small cigarettes was controlled within 1.2%,the puncture in the cigarette was also basically controllable.Therefore,it was suggested that the percentage of stem in the leaves of thin-branch and high-grade cigarette materials should be controlled below 1.2%,and that of other cigarette materials should be controlled below 1.5%.
