Method for rapidly determining actual blending ratio of cut stems in cut tobaccos

The invention discloses a method for rapidly determining an actual blending ratio of cut stems in cut tobaccos. The method comprises the following steps of (1) testing the content of nicotine and chlorine in the cut leaves and the cut stems; (2) calculating the content of nicotine and chlorine in a mixed material according to a blending ratio; (3) quasi-testing the content of nicotine and chlorinein the cut tobaccos; (4) calculating out an actual proportion of the cut stems in the cut tobaccos; and (5) judging the reliability of XN and XCl, and taking an average value of XN and XCl as an actual proportion X of the cut stems in a cigarette. The method is free of modeling, simple and quick; and a result is accurate and reliable. 本发明公开了种跑条丝中的梗丝实掺比例的快速测定方法，包括以下步骤：①测试叶丝中和梗丝中的烟碱和氯含量；②按掺配比例计算掺配混合物料中的烟碱和氯含量；③准测试跑条丝中的烟碱和氯含量；④计算出跑条丝中梗丝实际占比；⑤对X、X进行可信度判定，取X、X的平均值即为烟支中梗丝实际占比X。本发明的方法无需建模、简单快速，结果准确可靠。
