Development of a Three-Stage and Six-Step Curing Technology for Flue-Cured Tobacco and Its Application

为解决我国烟叶烘烤过程中普遍存在的烤黄烤不香的问题,特介绍了三段六步式烘烤工艺的原理及关键参数,并对比分析了三段式工艺和三段六步式工艺的烘烤效果.结果表明,三段六步式烘烤工艺烟叶较对照的化学成分含量及比例更加适宜,提高了香气量、改善了香气量,评吸质量也较三段式烟叶得到了大幅提高.随着配套设置和工艺的不断完善,它必将在烟叶烘烤上得到广泛应用,为烟叶发展提供有力的技术保障.

To solve the widely existing problems of curing in tobacco industry, this paper proposes a ＂three-stage and six-step curing method＂ and introduces its working principle and key parameters. Its curing effects are compared with those of the traditional three-stage curing method. The results show that the three-stage and six-step curing method results in more suitable ratios of total sugar/nicotine and nitrogen/nicotine, lower protein and starch content and higher aroma component content, and improves the comprehensive quality grade of tobacco leaves. With steady improvement of the accompanying devices and technology, the three-stage and six-step curing method is expected to be widely applied in tobacco curing, and provide strong supporting techniques to the development of tobacco industry.
