Effects of Tobacco Filling Coefficient in Cylinder on Tobacco Casing Uniformity

In order to investigate the influences of filling coefficient of tobacco in cylinder on the uniformity of tobacco casing, experiments were conducted at filling coefficients of 0.25, 0.21, 0.17, 0.13 and 0.10, and the uniformity of casing and the stability of moisture content in cased strips at different filling coefficients were analyzed. The results showed that:1) Filling coefficient affected casing uniformity to a certain extent. Within the range from 0.13 to 0.25, the casing uniformity increased with the decrease of filling coefficient, but decreased when the filling coefficient was less than 0.13. 2) Within the range from 0.13 to 0.25, the effects of filling coefficient on the stability of moisture content in output strips were negligible. However, the stability of moisture content would become worse when the filling coefficient was less than 0.13.
