打叶复烤成品长梗率的影响因素分析

Influencing Factors Analysis of the Long-stem Rate of Threshing and Redrying Products

通过对润叶、打叶、回梗系统参数调整、新型异形筛应用进行研究,结合叶片结构、烟梗结构检测结果,得出一套提升打叶复烤成品长梗率的关键参数模型,有效提高烟叶来料与设备工艺参数的匹配性,有利于提高打叶风分后的叶片和烟梗质量,提升成品长梗率,为复烤设备的调试和操作提供理论依据。

The system parameter adjustment of leaf moisturizing, threshing, back stem system, and the application of new special-shaped sieve were studied and optimized. Combined with the detection results of leaf structure and tobacco stem structure, a set of key parameter model for the improvement of long-stem rate of threshing and redrying products was drawn. The matching degree of incoming tobacco materials and equipment process parameters was effectively improved. It was beneficial to improve the quality of leaves and stems after threshing and air separation and improve the long-stem rate, which could provide theoretical basis for the debugging and operation of redrying equipment.
