松散回潮回风温度对云南烟叶加工物理质量和感官质量的影响

Effects of Recirculated Air Temperature in Ordering Cylinder on Physical and Sensory Quality of Yunnan Tobacco

为提高云南烟叶加工质量,发挥原料潜质,提高使用价值和有效利用率,通过云南烟叶不同回风温度试验,对不同加工条件下烟叶物理质量和感官质量变化趋势进行了研究。结果表明:①在加工物理质量方面,随回风温度增加,松散回潮出口烟叶温度和松散率逐渐增加,云南烟叶适宜的回风温度在68℃以上;②在感官质量方面,回风温度对烟叶香气特性、烟气特性、口感特性都会产生不同程度影响,松散回潮工序回风温度为64℃以下时,有利于云南烟叶感官质量的提高;③现有松散回潮设备性能不能完全满足保持云南烟叶感官质量和提升烟叶松散率等物理质量的加工需要。

In order to improve the processing quality, the experiments on Yunnan tobacco leaves at different recirculated air temperature in ordering cylinder were carried out, and the physical and sensory quality of tobacco leaves under different processing conditions were investigated, the result showed that： 1） in terms of physical processing quality, the temperature and loosening ratio of output tobacco increased gradually with the increase of recirculated air temperature, and the appropriate temperature was over 68℃ ; 2） in terms of sensory quality, recirculated air temperature affected the aromatic, smoke and mouth feeling characteristics of tobacco leaves at different degrees, the sensory quality of Yunnan tobacco would be improved when recirculated air temperature was under 64℃ ; 3 ） the ordering cylinder now in use is incompetent for keeping the sensory quality of Yunnan tobacco and raising its physical quality, such as loosening ratio, in one process step.
