| [目的]探索TB-S松散回潮机合理的烟叶松散率加工参数,为提高其松散回潮效果提供科学依据。[方法]分别对TB-S松散回潮机的加水比例、滚筒转速、松散流量和喷嘴蒸汽压力等因素进行单因素和正交试验,探讨这4个因素对烟叶松散率的影响。[结果]加水比例与烟叶松散率呈一元线性关系;滚筒转速和喷嘴蒸汽压力与烟叶松散率呈一元二次关系;松散流量明显影响烟叶松散率。影响主次顺序:滚筒转速 > 加水比例 > 喷嘴蒸汽压力 > 松散流量;最优工艺条件:松散回潮机加水比例为4.0%,滚筒转速为9.0 r/min,松散流量7 050 kg/h和喷嘴蒸汽压力为150 kPa时,可使烟叶松散率达到99.6%。[结论]合理控制松散回潮机的各关键设备参数,特别是滚筒转速,加水比例、喷嘴蒸汽压力等,可有效提高烟叶松散率。 |

| Abstract: |
| [Objective] In order to provide a scientific basis for improving the effect of loose resurgence,this paper studied the appropriate processing parameters of TB-S cylinder's loose resurgence.[Methods] We analyzed the effects of adding water ratio,roller speed,loose flow and steam pressure on tobacco leaves loose rate,using single factor trails and orthogonal test.[Results] The results showed that the adding water ratio and tobacco leaves' loose had a linear relationship,the roller speed and tobacco leaves' loose had a quadratic relationship,and loose flow significantly affected the loose rate of tobacco' loose.Their effect on tobacco leaves loose was ranged as follows:Roller speed > adding water ratio > nozzle steam pressure > loose speed.The optimum conditions were as follows:Loose water content of 4.0%,roller speed of 9.0 r/min,loose flow rate of 7 050 kg/h and nozzle steam pressure of 150 kPa,under which the leaf loose rate could reach to 99.6%.[Conclusion] Reasonable control of TB-S's key equipment parameters,especially roller speed,adding water ratio and nozzle steam pressure,can achieve the purpose of improving the rate of loose tobacco. |
