Design of a reclaiming system for cut tobacco in rejected tobacco stems by combining multi-stage screening with flexible pneumatic separation
摘要
Abstract
To reduce waste of cut tobacco in the process of tobacco stem rejecting during cigarette production,a reclaiming system was designed that combined multi-stage screening with flexible pneumatic separation.The system mainly consisted of three-stage vibration screens and a three-cavity,six-channel flexible pneumatic separator.After three-stage vibration screening,the rejected tobacco stems were divided into four categories:large material,medium material,small material and dust.The large,medium and small materials were then fed into the corresponding flexible pneumatic separation chambers for two rounds of independent pneumatic separation.Finally,fine separation of the cut tobacco and stems was achieved based on the difference in the suspension speeds of the materials.The system was tested using king-sized(Brand A)and semi-slim(Brand B)cigarettes.The results showed that this system had a good separation effect and significantly improved the efficiency of cut tobacco reclaiming.The reclaiming rates of cut tobacco from the rejected stems of Brands A and B were 88.20%and 84.04%,respectively,which was 62.52 and 44.30 percentage points higher than the rate achieved using single onsite pneumatic separation.This system provides technical support for reducing material consumption in cigarette production while optimizing the balance between production quality and consumption.关键词
