Relationship between Stem Content in Lamina and Tobacco Breakage

In order to maximize the comprehensive effectiveness in tobacco threshing and redrying, the experiments on different stem contents in lamina during tobacco threshing were conducted.The results showed that the content of lon g particle (over 12.7mm)and strip yield increased with the increase of stem content in lamina, while the fine particle (<3.18mm)content, fines under the screen after threshing and pneumatic separation, lamina content in stem and tobacco breakage reduced.It suggested that the tobacco breakage would be higher and strip yield be lower if the stem content in lamina was too low.
