摘　　要：[目的]研究打叶环节烟叶水分变化。[方法]通过调研3家卷烟工业企业2016年河南8个配打批次烟叶,了解了打叶过程中水分的变化情况,并通过河南X2F、B3F 2个等级烟叶在线试验,研究了打叶环节各级打叶单元水分变化趋势,分析了各级打叶单元水分变化对打叶质量的影响。[结果]随着打叶进程的推进,烟叶水分逐渐散失,1、2级打叶单元级间水分散失率相对较小,而3、4级打叶单元级间水分散失率则较大;低等级烟叶比高等级烟叶水分损失量大,烟末水分散失量较烟片水分散失量大;水分损失大的烟叶,在3、4级打叶单元大中片率下降较为明显。[结论]研究可为打叶环节烟叶的水分控制提供参考。[ Objective] In order to control the moisture content in threshing of flue-cured tobacco,the moisture content changing was studied.[Method ] Eight batches of blending threshing flue-cured tobacco of Henan in 2016 have been researched, and through the test of X2F, B3F tobacco of Henan on line, moisture changing trend of all levels threshing units were studied, the impacts of the changing moisture content of the all levels threshing units on threshing quality were analyzed. [Result] The results showed that as the threshing o n , the moisture content of the tobacco leaf had a loss gradually, the first and the second level of threshing unit had smaller loss in the moisture content than the loss in the moisture content of the third and the fourth level of threshing unit ; the loss in the moisture content of the lower leaf grads were bigger than that of the higher leaf grads,the loss in the moisture content of fines were bigger than that of lamina.the large and medium pieces rate of the lost moisture easily tobacco had distinct decline in the third and the fourth level of threshing unit. [ Conclusion ] The study can provide reference for the moisture control of leaf tobacco.
