Mature-delay tobacco leaf baking process

Abstract

The invention discloses a mature-delay tobacco leaf baking process, which relates to putting tobacco leaves in a baking barn and igniting. The process comprises the following steps: a, keeping dry-bulb temperature at 38 plus or minus 0.5 DEG C changelessly to roast for 4-6h; b, keeping the dry-bulb temperature at 40 plus or minus 0.5 DEG C changelessly to roast for 24-26h, keeping wet-bulb temperature at 39 plus or minus 0.5 DEG C within the first half of baking time, and keeping the wet-bulb temperature at 38 plus or minus 0.5 DEG C within the second half of baking time; c, keeping the dry-bulb temperature at 42 plus or minus 0.5 DEG C to roast for 26-28h; d, keeping the dry-bulb temperature at 44 plus or minus 0.5 DEG C to roast for 16-18h; e, keeping the dry-bulb temperature at 46 plusor minus 0.5 DEG C to roast for 14-16h; f, keeping the dry-bulb temperature at 48 plus or minus 0.5 DEG C to roast for 10-12h; g, keeping the dry-bulb temperature at 50 plus or minus 0.5 DEG C to roast for 8-10h; h, keeping the dry-bulb temperature at 54 plus or minus 0.5 DEG C to roast for 5-7h; i, keeping the dry-bulb temperature at 60 plus or minus 0.5 DEG C to roast for 7-9h; j, enabling the dry-bulb temperature to rise to 65-68 DEG C at the rate of heating up 1 DEG C every hour; keeping the dry-bulb temperature between 65 DEG C and 68 DEG C to roast for 19-21h; and finishing roasting.

Description

technical field

[0001] The invention relates to the primary processing and baking process of fresh tobacco leaves in tobacco agriculture, especially the curing process of dark storm tobacco leaves formed under special circumstances. Background technique

[0002] The existing black storm tobacco leaf curing technology is often more qualitative and less quantitative, and lacks targeted specific operation methods. The temperature and humidity control points in the curing technology are relatively few and broad, and there is a lack of precise control points. During the curing process, the tobacco leaves turn yellow and lose water. Uncoordinated, high color fixing temperature, long drying time of tobacco leaves dehydration, easy to cause browning reaction, poor softness, not bright gloss, insufficient porosity or stiff leaves after roasting. Smoking quality problems of sensory evaluation with insufficient taste. Contents of the invention
