密集烘烤定色和干筋期风机转速对上部烟叶外观质量和内在品质的影响
Effects of fan speed during leaf drying and stem drying stage of bulk curing on the appearance quality and internal quality of upper leaves in flue-cured tobacco
摘要
Abstract
To improve the quality of upper flue-cured tobacco leaves and optimize curing technology, effects of fan speed controlled by inverter during the leaf drying and stem drying stage of bulk curing on appearance quality, chemical components and their harmony, content of aroma components, and the smoking quality of upper flue-cured tobacco were studied. The results showed that the fan speed of bulk curing had an important influence on the formation of appearance quality and internal quality of upper leaves. Properly reducing fan speed could greatly improve the quality of upper flue-cured tobacco leaves, and in the study, T3 (dry bulb temperature 42～47 ℃ , fan speed was 1 440 r · min -1; 47 ~ 60 ℃ , 960 r · min-1 ,60 ~68 ℃ , 720 r · min-1) treatment obviously improved the appearance quali-ty, chemical components harmony and the smoking quality, and significantly increased the content of most of the aroma components. Upper leaves from T3 had the characteristics of preferable note, ade-quate aroma amount, clean aroma quality, little irritation, moderate density and strength, less offen-sive taste and good taste. To a certain degree, T3 treatment improved the availability of upper leaves.关键词
