Abstract
In order to prevent cut strips from tangling in EVA dryer, the technical process of EVA drying and the factors causing cut strips tangling were analyzed. The following measures were then adopted: 1) Optimizing EVA operating parameters and changing the flow pattern of processing gas. 2) Adding a loosening device for loosening cut strips. 3) Changing the spreading mode of spreading vehicle from strip to stepping to prevent cut strips from being squeezed. 4) Replacing the knife blades to cut tobacco to fixed-length and decrease long strands. The results showed that: 1) The volume and temperature of processing gas were the significant factors causing cut strips tangling, the lowest tangling rate reached when the gas volume and temperature were set at 16 500 kg/h and 170 ℃, respectively. 2) After improvement, the tangling rate and breakage of cut strips decreased by 11.18 and 0.51 percentage points, the long strand percentage and filling value increased by 3.4 percentage points and 0.34 cm3/g, respectively. The utilization rate and the processing quality of cut strips were promoted.关键词
