摘要

[目的]将热泵及其配套技术应用到实际烟叶烘烤中，比较热泵烤房与普通烤房烤后烟叶化学成分及其感官质量。[方法] 以云烟87品种烟叶为材料，对热泵烤房和普通烤房条件下的烤后烟叶进行了常规化学成分、外观质量以及评吸结果分析。[结果]试验表明，在热泵烤房烘烤的烟叶化学成分协调性优于普通烤房烘烤的烟叶，其总糖、还原糖、总氮、钾含量高于普通烤房烘烤的烟叶，而烟碱含量低于在普通烤房烘烤的烟叶；热泵烤房烘烤的烟叶成熟度、身份、结构优于普通烤房的煙叶，而色度、油分略低于普通烤房；热泵烤房烘烤的烟叶香气质、香气量、浓度、余味、劲头优于普通烤房，但是杂气、刺激性比普通烤房大。[结论] 研究可为提高烤后烟叶的品质、推广应用热泵烤房提供参考。

Abstract[Objective] Using heat pump and supporting technology in actual tobacco curing process， the chemical components and sensory quality of flue-cured tobacco in heat pump curing barn and common curing barn were compared. [Method] With Yunyan No.87 as material， the chemical components， appearance quality and smoking evaluation results were analyzed. [Result] The results showed that in the heat pump， coordination of chemical components of tobacco leaf is better than the common barn roasted tobacco leaf， total sugar， reducing sugar， total nitrogen， potassium content is higher than common barn roasted tobacco leaf. The nicotine content is lower than that in the common barn roasted tobacco leaf. In heat pump barn roasted tobacco leaf maturity， identity， structure is better than common barn tobacco leaves， and chroma， oil is slightly lower than the common barn. Heat pump barn baking tobacco leaf aroma， aroma quantity， concentration， aftertaste， momentum is better than the common barn， but mixed gas， irritation than common barn big. [Conclusion] The study can provide reference for tobacco quality improvement after curing， and heat pump curing barn extension.

我国烟叶初烤中长期且广泛使用燃煤烘烤。近些年随着现代烟草农业的发展，烤房的改进以及煤炭替代能源开发在烟叶生产中越来越受重视[1]。使用燃煤烘烤导致烤烟房内的温度升温不均匀且温度变化较大，导致烤出的烟叶质量不好。同时，煤炭是不可再生能源，无休止的开采和消耗最终将导致其快速枯竭。此外，燃烧煤、薪柴等燃料释放出来的二氧化碳是温室气体增加的主要来源[2]，煤炭燃烧所产生的二氧化硫等有害物质严重污染了大气环境，影响人们的身体健康。……
