Relationship of Cut Tobacco's Temperature to its Breakage Rate and Size Distribution

Cut tobacco size distribution equation was used to analyze the influences of temperature on the breakage rate and size distribution of shattered cut tobacco, the results showed that:within the test temperature range, 1)the breakage rate of cut tobacco decreased with the rise of temperature; cut tobacco of the cigarette of different grades in the order of breakage rate at the same temperature were Grade Ⅲ> Grade Ⅱ> Grade Ⅰ; in the order of its susceptible to temperature were Grade Ⅰ>Grade Ⅱ>Grade Ⅲ; 2)the variations of size distribution of shattered cut tobacco at different temperatures were mainly represented by the variations of the percentage of cut tobacco in a certain length range, which were 1.4-2.0, 0.7-2.0, 1.4-2.8 mm for Grade Ⅰ, Ⅱ and Ⅲ, respectively; 3) the uniformity of cut tobacco structure decreased with the rise of temperature.
