A kind of roasting method of honghuadajinyuan variety multifertility tobacco leaves

Abstract

The invention discloses a bulk curing method, capable of increasing tobacco curing quality, of Honghua Dajinyuan multi-fertilizer tobacco and belongs to the technical field of tobacco curing. The method is characterized in that the tobacco is sufficiently heated and preliminarily softened in the initial stage of yellowing, dry ball temperature is lowered to 35-36 DEG C in the medium stage of the yellowing so as to perform low-temperature yellowing, tobacco yellowing degree is lowered appropriately and fire is transferred in advance in the late stage of the yellowing, stable moisture discharge and stable color fixing are performed in the initial stage of color fixing, tobacco yellowing and sufficient water loss and withering of the tobacco are guaranteed, the risks of greened, black and mixed-color tobacco are lowered, and other operation is performed according to a conventional curing process; by the steps above, a large amount of greened, black and mixed-color tobacco caused by insufficient water loss during yellowing or excessive water loss during yellowing of the Honghua Dajinyuan multi-fertilizer tobacco during the curing process is avoided. The method is high in operability, scientific, practical and capable of evidently increasing tobacco curing quality.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf curing, and in particular relates to an intensive curing method for the multifertile tobacco leaves of the Honghua Dajinyuan variety. Background technique [0002] Due to the influence of the special ecological and climate factors in each tobacco area, the cultivation and production technology is not in place, and some fresh tobacco leaves with poor quality and difficult to be cured will be formed. The unique baking method achieves the effect of fixing and highlighting the quality. [0003] Fertility tobacco leaves are produced when the soil is relatively fertile or the supply of fertilizer and water is relatively high, the nutrients are uncoordinated, the leaves have strong water retention, the contents are still sufficient, the dry matter is less and mainly nitrogen-containing compounds, and the carbohydrate content is relatively low, so it is not tolerant in the field. Mature, it is not r...

Problems solved by technology

[0002] Due to the influence of the special ecological and climate factors in each tobacco area, the cultivation and production technology is not in place, and some fresh tobacco leaves with poor quality and difficult to be cured will be formed. The unique baking method achieves the effect of fixing and highlighting the quality

[0003] Fertile tobacco leaves are produced when the soil is relatively fertile or the supply of fertilizer and water is relatively high, the nutrients are uncoordinated, the leaves have strong water retention, the contents are still substantial, the dry matter is less and mainly nitrogen-containing compounds, and the carbohydrate content is relatively low, so it is not tolerant in the field. Mature, it is not resistant to baking during the baking process, it is easy to turn yellow and not enough to bake green, and it is easy to hang ash and bake black due to excessive consumption of dry matter due to prolonged yellowing, and it is also easy to concentrate evaporation of water during the color fixing period, resulting in exhaustion. Difficult to wet, resulting in steamed flakes and bad flakes

[0004] The leaf pigment content of Honghua Dajinyuan variety is higher than that of other varieties. During the curing process, it shows slower yellowing and faster water loss, which is easy to cause the occurrence of green-cured tobacco leaves; although it can be improved by prolonging the yellowing time or increasing the yellowing temperature Solve the problem of insufficient yellowing of tobacco leaves, but prolonging the yellowing time will easily lead to excessive consumption of tobacco leaf substances, and increasing the yellowing temperature will easily lead to excessive consumption of tobacco leaf substances, and tobacco leaves are easily browned to produce black dregs
