Possessed by of the invention the utility model has the advantages that
Power consumption is decreased obviously after the transformation of bulk curing barn frequency converter, saves electric energy up to 30% or so, and wind speed is soft, and tobacco leaf dehydration becomes Yellow, dry incremental, aroma substance forms a large amount of precipitating accumulation, and chemical component is coordinated, and tobacco leaf industrial application, which is worth, to be improved.It is close Collection baking circulating fan frequency converter difference control strategy whether in terms of energy-saving effect or baking quality of tobacco have it is larger Promotion.Influence result of the different phase difference wind speed to cured tobacco leaf aroma substance and judging parameter during dense drying Show, later yellowing stage and fixation latter stage make phenylalanine class total amount in tobacco leaf, the content highest of western cypress alkane substance.Yellowing stage Wind speed is that 20-30HZ is conducive to carotenoids total amount, and the formation of brown reaction product substance and neophytadiene turns yellow The judging parameter that latter stage and fixation latter stage wind speed are 35-50HZ is best.
Fragrance is the main contents of quality of tobacco, the perfume quantity of tobacco leaf, aroma quality be by various cause perfumery constituent contents, than That example and interaction codetermine has research to think both at home and abroad, the most of flavescence in baking of aroma substances in flue-cured tobacco, fixation stage It is formed, may be decomposed to dry muscle later period aroma substance, therefore turned yellow and drying muscle stage temperature condition and wind speed size are to the perfume (or spice) of tobacco leaf It is jealous that there is decisive influence.
Later yellowing stage extends the degradation that baking time is conducive to pigment, and research is thought: with the extension chlorophyll of baking process It is small that degradation speed shows as early period slow decomposition amount;Mid-term is accelerated, and decomposition amount is more;Later period slows down until stopping chlorophyll degradation The phytol of generation, some dehydration is changed into neophytadiene, AMIN result of study table in tobacco leaf maturation and modulated process It is bright, have 15% in modulation Chlorophyll Degradation product phytol, 30% increases as neophytadiene.During tobacco leaf modulation, alcoholization, Carotenoid substance not only continues to increase neutral flavor substance total amount, but also its catabolite continues to convert, such as oxygen Change, restore and be dehydrated etc., generate the compound more useful to fragrance matter.
