Problems solved by technology

The currently promoted and used intensive curing barn supporting baking process is a technical reference basic specification applicable to all varieties and commonly used. The degree of distinctiveness is decreasing year by year, and the quality of tobacco leaves is poor in shrinkage, not soft, less oily, light in color, and insufficient in aroma. Higher, resulting in reduced industrial availability

Embodiment 1

[0021] The lower leaves are roasted, and the tobacco leaves of Yunyan 87 variety are harvested when the fresh tobacco leaves are normally mature, and the freshly picked tobacco leaves are woven into poles and loaded on the kang. 36°C, keep the wet bulb at 35°C, and bake at a steady temperature for 6-8 hours, until the whole kang tobacco leaves heat up and sweat, and the leaf tip turns yellow obviously; raise the dry bulb temperature to 39°C at a heating rate of 1°C / 2h, and wet The temperature of the bulbs is raised to 36°C, and the lower leaves are baked at a steady temperature for 12-20 hours until the lower leaves of the high-temperature layer tobacco leaves turn yellow by 70%, are basically slightly green, and become soft and collapsed; Increase the temperature to 42°C, control the wet bulb temperature at 36°C, and bake at a steady temperature for 12-16 hours until more than 80% of the tobacco leaves in the high-temperature layer have yellow flakes and tendons, the leaves lo...

Embodiment 2

[0023] The middle and upper leaves are roasted, and the tobacco leaves of Yunyan 87 variety are harvested when the fresh tobacco leaves are normally mature, and the freshly picked tobacco leaves are weaved into poles and loaded on the kang. to 35°C, keep the wet bulb at 34°C, and bake at a steady temperature for 8-12 hours until the whole kang tobacco leaves heat up and sweat, and the tip of the leaf turns yellow obviously; raise the temperature of the dry bulb to 38°C at a heating rate of 1°C / 2h, The wet bulb temperature is increased to 37°C, and the temperature is stable for 20-30 hours, until the lower leaves of the high-temperature layer tobacco leaves turn 70-80% yellow, basically slightly green, soft and collapsed, and the middle and upper leaves are basically all yellow, with yellow veins and blue veins. Soft and collapsed; increase the dry bulb temperature to 41-42°C at a heating rate of 1°C / 2h, control the wet bulb temperature at 37°C, and bake at a stable temperature ...

Abstract

The invention relates to the technical field of tobacco conditioning processing, in particular to an intensive flue-curing process for softening and flavoring Yunyan 87 tobacco by flue-curing. By theaid of the process, the proportions of green-containing and impurity-containing tobacco and smooth tobacco can be reduced, so that style, characteristics and potential quality of the 87 variety can beeffectively presented. The process comprises the following steps: tobacco pretreatment; early stage of yellowing: dry-bulb temperature is 35-36 DEG C, wet-bulb temperature is 34-35 DEG C and constant-temperature flue-curing is performed for 6-12 h; middle stage of yellowing: dry-bulb temperature is 38-39 DEG C, wet-bulb temperature is 36-37 DEG C and constant-temperature flue-curing is performedfor 12-30 h; later stage of yellowing: dry-bulb temperature is 41-42 DEG C, wet-bulb temperature is 36-37 DEG C and constant-temperature flue-curing is performed for 12-24 h; early stage of fixation:dry-bulb temperature is 43-44 DEG C, wet-bulb temperature is 36-37 DEG C and constant-temperature flue-curing is performed for 8-16 h; middle stage of fixation: dry-bulb temperature is 47-48 DEG C, wet-bulb temperature is 37-38 DEG C and constant-temperature flue-curing is performed for 20-30 h; later stage of fixation: dry-bulb temperature is 52-54 DEG C, wet-bulb temperature is 38-39 DEG C and constant-temperature flue-curing is performed for 12-24 h; early stage of stem drying: dry-bulb temperature is 59-60 DEG C, wet-bulb temperature is 39-40 DEG C and constant-temperature flue-curing is performed for 4-6 h; later stage of stem drying: dry-bulb temperature is 67-68 DEG C, wet-bulb temperature is 40-42 DEG C and constant-temperature flue-curing is performed for 24-36 h.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf modulation and processing, in particular to an intensive roasting process for Yunyan 87 tobacco leaves to be softened and fragrant. Background technique [0002] Tobacco leaf curing is a key link in the production of flue-cured tobacco. It has strong technical operability and plays a decisive role in the formation of the final quality of tobacco leaves. The Yunyan 87 variety is currently the main variety of tobacco leaf planted in various production areas across the country. Because of its prominent style, it plays an important role in cigarette formulations. The currently promoted and used intensive curing barn supporting baking process is a technical reference basic specification applicable to all varieties and commonly used. The degree of distinctiveness is decreasing year by year, and the quality of tobacco leaves is poor in shrinkage, not soft, less oily, light in color, and insufficien...
