Baking method for lower tobacco leaves of Chinese tobacco 101

Abstract

The invention discloses a baking method for lower tobacco leaves of Chinese tobacco 101. The method comprises the following steps that S1, the tobacco leaves are treated before baking; S2, the tobaccoleaves treated in S1 are placed in a baking room, the dry-bulb temperature of the baking room is raised to 45-50 DEG C at 0.5 DEG C / h, and the tobacco leaves are kept for 10-15 hours under the condition that the wet-bulb temperature is 36-37 DEG C, so that the leaves at the low temperature layer achieve the effects that the leaves and ribs turn yellow, the tips are hooked, the edges are rolled, and there is no green ribs in a whole furnace; S3, the dry-bulb temperature is raised to 50 DEG C at 1 DEG C / h, the wet-bulb temperature is controlled to be 37-38 DEG C, the temperature is kept for 8-10 hours, so that the leaves at the high temperature layer are large coils, and half drying is conducted; S4, the dry-bulb temperature is raised to 54 DEG C at 1 DEG C / h, the wet-bulb temperature is controlled to be 38-39 DEG C, the temperature is kept for 15-20 hours, and therefore the leaves in the whole baking room are completely dried; S5, the dry-bulb temperature is raised to 60 DEG C at 1 DEGC / h, the wet-bulb temperature is controlled to be 39-40 DEG C, and the temperature is kept for 5 hours, so that the tobacco ribs begin to shrink and turn brown, and 2 / 3 or above of the tobacco ribs are dried; S6, the dry-bulb temperature is raised to 68 DEG C at 1 DEG C / h, and the wet-bulb temperature is controlled to be 40-41 DEG C. By means of the method, the appearance and intrinsic quality ofthe lower baked tobacco leaves of the Chinese tobacco 101 can be effectively improved.

Description

technical field [0001] The present invention relates to the technical field of flue-cured tobacco, in particular to a method for curing the lower tobacco leaves of the middle tobacco 101 . Background technique [0002] Baking is a key link in forming the quality of tobacco leaves. Tobacco leaf curing fully reveals and exerts the excellent traits formed and accumulated in the field growth process of tobacco leaves. It is a crucial technical link in the production of high-quality tobacco leaves, and it is also one of the technical bottlenecks for improving the quality and efficiency of flue-cured tobacco production. With the development of flue-cured tobacco production, the current purpose of tobacco leaf curing is not only to "dry and yellow" the tobacco leaves, but also to adopt effective technical measures during the curing process to promote the post-ripening of the tobacco leaves and make the tobacco leaves "fresh and roasted". Cooked and roasted aroma", improve the appe...

AI Technical Summary

Problems solved by technology

Tobacco leaves of different varieties and different parts can be flexibly adjusted on the basis of the basic mode to implement contingency roasting, but this requires higher requirements for roasting personnel. The roasting technology applicable to this variety is likely to cause the phenomenon of roasted green and roasted smoke

At present, there are many researches on the curing technology of different varieties in China. The curing technology of flue-cured tobacco varieties such as Honghua Dajinyuan, Cuibi No. 1, NC102, NC297, KRK26, Yunyan 99, Yunyan 116, and Zhongyan 100 have been reported. , in recent years, Shandong flue-cured tobacco planting area has promoted the planting of China Tobacco 101 variety when adjusting the variety layout. Since this variety was planted on a large scale in Shandong tobacco area for the first time, some roasters are not sure about its roasting characteristics, especially the lower part. Tobacco leaves are difficult to bake, resulting in bad smoke
