Background
With the continuous upgrading of the technical level of cigarette technology and the rapid development of novel cigarette products such as 'middle-end fine-explosion', new requirements with homogenization processing as the core are provided for the product quality in the threshing and redrying link by cigarette industry enterprises. The tobacco leaf structure index is one of important indexes for measuring the homogenization processing level, directly influences the filling capacity and the rolling effect of the cigarette tobacco shreds, and is the basis for stabilizing the quality of the cut tobacco shreds. In recent years, domestic and foreign researches show that the optimal range of the tobacco leaf size is 10-35 mm, because the filling capacity of tobacco shreds is sharply reduced when the tobacco leaf size is less than 10mm, and the filling capacity is not obviously increased when the tobacco leaf size is more than 35mm, and the efficiency of a cigarette making machine is influenced. Therefore, the requirements of cigarette industry enterprises on the structural indexes of the threshed tobacco leaves are changed from the aspect of improving the large and medium leaf rate to the aspect of reducing and increasing the large and medium leaf rate.
