摘　　要：目前烟草行业主要从叶丝的净化和误剔率方面研究两级风选的控制技术,但鲜有研究其关键参数对风选后叶丝质量影响的报道。该项目在保证风选稳定性的基础上,从风选风量和除尘风量变化对烟丝感官质量和物理质量的影响程度入手,研究两级风选的控制技术及方法。同时,对比分析风选前不同烟丝来料特性对风选效果的影响。研究结果表明,系统中风选风量的大小、除尘风量的占比对风选后烟丝感官质量影响重大,气流烘后烟丝因温度较高且含有大量蒸汽使其柔韧性及抗造碎性均较薄板烘后烟丝强,故风选后烟丝缠绕率较高。该研究结果可充分发挥两级风选设备对产品质量的贡献度,以及为该设备在工艺控制方面提供理论依据和技术支持。At present,the tobacco industry mainly studies the control technology of two-stage winnowing from the aspects of purification and false picking rate of leaf silk,but there are few reports on the impact of its key parameters on the quality of leaf silk after winnowing.On the basis of ensuring the stability of winnowing,this project studies the control technology and method of two-stage winnowing based on the impact of changes in winnowing air volume and dust removal air volume on the sensory quality and physical quality of cut tobacco.At the same time,the influence of different tobacco feed characteristics on the winnowing effect before winnowing was compared and analyzed.The research results show that the size of the winnowing air volume and the proportion of the dust removal air volume in the system have a significant impact on the sensory quality of the cut tobacco after winnowing.The cut tobacco after air-dried has higher temperature and contains a large amount of steam,which makes its flexibility and resistance to crushing are higher than that after thin-dried tobacco.Therefore,the winding rate of the cut tobacco after winnowing is higher.The research results can give full play to the contribution of two-stage winnowing equipment to product quality and provide theoretical basis and technical support for the equipment in terms of process control.
