摘  要:
为了探索可变频热泵密集烤房在烟叶烘烤各阶段的适宜风速参数,以云烟116 为材料,研究了不同烘烤阶段不同风速条件下烟叶主要化学成分的变化.结果表明:调整变频风机参数后,烟叶内部化学成分含量更加合理,化学成分评分达到 90.7,淀粉含量降低至 1.3%,感官质量提高.具体参数:38℃(干球温度)前,风机转速保持750~800 r/min;38~42℃阶段,风机转速保持 800~850 r/min;42~48℃阶段,风机转速保持 1 300~1 350 r/min;48℃后风机转速保持 800 r/min.综上所述,改良风速参数能够提高烟叶品质,降低烟叶淀粉含量.

摘  要:
In order to further explore the suitable wind speed parameters in each stage of variable frequency heat pump bulk curing barn,Yunyan 116 was used as the material to study the change trend of main chemical components of tobacco leaves under different stages and different wind speed conditions.The results showed that the content of chemical components in tobacco leaves was more reasonable after adjusting the parameters of variable frequency fan.The chemical composition was assigned to 90.7,the starch content was reduced to 1.3%,and the sensory quality was improved.The specific parameters were as follows:the fan speed was maintained at 750-800 r/min before 38℃(dry bulb temperature),and the fan speed was maintained at 800-850 r/min between 38-42℃.In the 42-48℃stage,the wind speed is maintained at 1 300-1 350 r/min;after 48℃,the fan speed is maintained at 800 r/min.In summary,the improved wind speed parameters can improve the quality of tobacco leaves and reduce the starch content.
