基于模糊综合评判的不同风机转速对烤烟上部叶可用性影响的研究

Effect of different fan speeds on usability of upper flue-cured tobacco leaves based on fuzzy comprehensive evaluation method

【目的】研究密集烘烤不同风机转速对烤烟上部叶的影响,为优化密集烘烤工艺及提高烤烟上部叶可用性提供理论依据。【方法】以G80上部叶(15～17叶)为材料,采用模糊综合评判,探讨密集烘烤不同风机转速对其化学成分可用性与外观质量的影响。【结果】相对于常规密集烘烤(风机转速保持不变),密集烘烤过程中适当降低风机转速,在一定程度上能够提高上部烟叶化学成分可用性,明显改善烤后外观质量,提高烤烟品质,其中以变黄期和定色前期风机转速1440r/min、定色后期960r/min、干筋期720r/min的效果最佳。【结论】密集烘烤过程中适当降低风机转速能明显改善上部烟叶化学成分可用性与外观质量。

[Objective]The present experiment was conducted to optimize intensive curing technology for improving usability of upper flue-cured tobacco leaves.[Method]The effects of different fan speeds on chemical composition and sensory quality of tobacco leaves（15th-17th） （cultivar G80） were studied using fuzzy comprehensive evaluation method.[Result]Compared to conventional intensive curing（control） ,the chemical composition,sensory quality and other quality parameters in upper leaves of flue-cured tobacco were improved after lowering the fan speed.The fan speed at 1440 rpm during yellowing stage and early leaf-drying stage,960 rpm during late leaf-drying stage and 720 rpm during stem-drying stage gave the best results.[Conclusion]Lowering the fan speed appropriately during bulk curing improved the chemical composition and sensory quality of upper flue-cured tobacco leaves.
