To control the blending uniformity more reasonably in tobacco threshing and redrying, minimize fluctuation of nicotine content in processed strips and ensure quality consistence of cigarette, the nicotine content in tobacco leaf was taken as a parameter in tobacco blending, 3 different blending methods, chemical component adjusting, mixed selection, the combination of the two, were separately tested, and the coefficient of variation (CV) of nicotine content in strips of tested blends was compared. The results showed that the average values of CV of nicotine content were all below 4 %.
