Embodiment 1

[0013] A certain place in Guizhou Province adopts loose leaf baking, adopts the method of the present invention:

[0014] ⑴Baking operation technology in yellowing stage

[0015] After loading the smoke, close the barn door, air inlet and moisture exhaust window, ignite and turn on the fan. The wet bulb temperature is controlled at 33°C, and the temperature in the barn is raised to 34°C at a rate of 1°C every 1 to 2 hours to stabilize the temperature. Baking until the tobacco leaves become soft, start to turn yellow, and the leaf tips are slightly lodging; increase the temperature to 38°C at a rate of 1°C every 1 to 2 hours to stabilize the temperature, control the wet bulb temperature at 35°C to 36°C, and bake until the tobacco leaves Turn yellow to 80% yellow to 90% yellow, and leaf tip lodging; control the wet bulb temperature to 34°C, raise the temperature to 40°C at a rate of 1°C every 2h, and bake at a steady temperature for 10h; control the wet bulb temperature to 33°C,...

Embodiment 2

[0021] A certain place in Fujian Province adopts tobacco clamping tobacco baking, adopts the method of the present invention:

[0022] (1) Baking operation technology in the yellowing stage

[0023] After loading the smoke, close the barn door, air inlet and moisture exhaust window, ignite the fire and turn on the fan. The wet bulb temperature is controlled at 35°C, and the temperature in the barn is raised to 36°C-38°C at a rate of 1°C every 1-2 hours. Stabilize the temperature and bake until the tobacco leaves become soft and start to turn yellow; control the wet bulb temperature at 35°C to 36°C, raise the temperature to 39°C to 40°C to stabilize the temperature, and bake until the tobacco leaves turn yellow to 80% to 90% yellow ; Control the wet bulb temperature at 34°C to 35°C, raise the temperature to 42°C at a rate of 1°C every 3 hours, and bake at a steady temperature for 20 hours.

[0024] (2) Baking operation technology in the color-fixing stage

[0025] After turni...

Abstract

The invention relates to a "two long and one short, low-humidity and slow-curing" flue-cured tobacco curing process, which belongs to the technical field of tobacco leaf curing. The main baking stages of the flue-cured tobacco curing process include the yellowing stage, the color-fixing stage and the gluten-drying stage. From the late stage to the middle stage of color fixation, the baking humidity is reduced and the temperature rise rate is slowed down. The entire baking process is controlled by an automatic temperature and humidity control system for flue-cured tobacco. The "two long and one short, low humidity and slow roasting" flue-cured tobacco curing process of the present invention improves the whole set of flue-cured tobacco curing process under the condition of increased density in dense curing rooms, simplifies the curing process and solves the problem of light color of tobacco leaves, insufficient oil content, The problem of insufficient aroma; it is suitable for different tobacco packing methods of loose leaves, and it is also suitable for the drying of flue-cured tobacco with the hanging rod and the tobacco clip packing method after the density of tobacco packing is increased.

Description

technical field [0001] The invention relates to a "two long and one short, low-humidity and slow-curing" flue-cured tobacco curing process, which belongs to the technical field of tobacco leaf curing. Background technique [0002] At present, the flue-cured tobacco curing process used mainly includes two types, one is based on the three-stage conventional drying process of hanging tobacco, and the other is the low-humidity loose leaf curing process. From 2004 to 2006, the intensive curing technology of flue-cured tobacco was gradually perfected through the test and promotion of intensive curing barns all over the country. From 2004 to 2007, Guizhou Tobacco Research Institute researched and developed a local patented technology (Patent No. 200710077916.7) "Dense Baking Room Loose Leaf Roasting Process". In recent years, with the problems of light color, insufficient oil content and insufficient aroma in the curing of flue-cured tobacco, the existing curing technology, includ...
