Abstract: In order to improve the processing quality of cut stem, the effects of five processing parameters, including stem screening, stem flattening, cut width, expansion intensity (ratio of gas to material) and drying means, on the quality of flake-shaped cut stem and roller cutting stem were investigated. A stem processing procedure, which included stem screening, roller cutting, and related loosening and spreading operating steps but included no stem flattening step, was proposed and verified via practical application. The results showed that: 1) Stem screening promoted the physical quality of flake-shaped cut stem, increased the proportion of long cut stem, and reduced the proportions of integral, medium, short and broken cut stems. 2) Compared with cut flattened stem, the form coefficient of flake-shaped cut not flattened stem presented an upward trend, and the cut stem showed batter softness and shatter resistance. 3) With the increase of expansion intensity, the form coefficient of flake-shaped cut stem raised. When cut width was 0.15 mm and the ratio of gas to material was 0.33, flake-shaped cut stem had relatively better processing endurance and the best shatter resistance. 4) Compared with cylinder drying, pneumatic drying would give flake-shaped cut stem better form coefficient and roller cutting stem had higher filling value and elasticity. 5) Compared with conventional cut stem, roller cutting stem featured smaller size, good filament-like appearance, higher size uniformity and width, and good compatibility and smoking quality. This study provides a support for improving the uniformity of cigarette blends.
