摘要
以K 326中部烟叶为试验材料,研究了密集烤房叠层加密装烟条件下不同风机频率对烤后烟叶外观质量、物理特性、常规化学成分及协调性和评吸质量的影响,结果表明,与对照相比,在烘烤过程中适当降低循环风机频率,烤后烟叶的外观质量、物理特性有所改善;淀粉、蛋白质和烟碱含量降低,糖含量和石油醚提取物增多,常规化学成分的协调性更好.总体上,密集烘烤过程中变频风机在变黄期以30 Hz-35 Hz-40 Hz和35 Hz-35 Hz-40Hz,定色期以45 Hz-30 Hz-30 Hz和50 Hz-35 Hz-25 Hz,干筋期以30 Hz和25 Hz,烤后烟叶香气量足,香气质较好,烟气浓度合适,刺激性小,杂气较少,余味较舒适.
The effects of different fan frequency on the appearance quality, physical property, chemi- cal components and smoking quality on the basis of laminated loading bulk curing were studied, with the middle leaves of K326 as the materials. The results showed that reducing fan frequency appropri- ately during the bulk curing could improve appearance quality and the physical property compared with the control. Besides, the contents of starch, protein and nicotine reduced and the contents of sugar and petroleum ether extract increased with better harmony of conventional chemical composition. In all, the frequency of inverter was suitable at 30 Hz-35 Hz-40 Hz and 35 Hz-35 Hz-40 Hz in the yellow periods, 45 Hz-30 Hz-30 Hz and 50 Hz-35 Hz-25 Hz in the leaf drying stage and staining 30 Hz and 25 Hz in the stem-drying stage, in the situations, the sensory evaluation of cured tobacco indicated that aroma quality was much better with sufficient content, good aroma quality, suitable smoke concentration, small bitting taste, less offensive odor, and comfortable aftertaste.
