AI Technical Summary
In the existing technology, the stems are not thoroughly sorted in the leaf cooling process of the cigarette making line, which leads to a decline in the quality of cigarette products, such as easy puncture of cigarettes, falling off of the combustion cone and "blooming cigarettes", and the recovery rate of usable leaf filaments is low.
A combination of a lifting feeding device, a primary vibrating overhead screen, an air separator, and a secondary horizontal vibrating screen is used to remove stems and recover usable tobacco leaves through multi-stage screening and air separation, thereby improving the purity of the tobacco.
It significantly increases the amount of stems removed, reduces cigarette defects, improves the purity of tobacco and the recovery rate of leaf shreds, and reduces the pressure of subsequent rolling.
