Embodiment 1

[0014] Embodiment 1 To the loose leaf baking of a certain local tobacco in Guizhou Province, adopt the following baking process:

[0015] After loading the smoke in the barn, ignite and bake for 15-20 hours to enter the yellowing stage.

[0016] (1) Baking operation technology in the yellowing stage

[0017] Operation requirements: the change of tobacco leaves reaches full yellow (full yellowing), and the leaves become soft; in the later stage of yellowing, a small amount of moisture is drained first, and then the temperature is raised to fix the color; the baking guidance time of the yellowing stage: 45-50 hours for the lower tobacco leaves, and 45 to 50 hours for the middle and upper tobacco leaves. Tobacco leaves are 55-65 hours.

[0018] Operation method: In the early stage of yellowing, the dry bulb temperature is 32 ℃ ~ 35 ℃, and bake at a steady temperature for 10 to 25 hours. After the tobacco leaves are slightly lodging, the dry bulb temperature is raised to 38 ℃; in...

Abstract

The present invention discloses a roasting technics with loose-tobacco curing bulk barn, wherein the main roasting stages include a yellowing stage, a fixation stage and a stem-drying stage. The present invention is characterized in that the technics is provide with stepped temperature rise to carry out the tobacco roasting, wherein the temperature is raised with a transition no less than 1 DEG C between different temperature grads, and steady-temperature roasting is provided for each roasting stage, wherein an automatic controlling system on roasting humidity and temperature of the tobacco is provided throughout the roasting process. The roasting technics with loose-tobacco curing bulk barn provided by the present invention solves the problem of the poor roasting penetrability of the tobacco, and the problems including the thin slice of the roasted tobacco, the failed stretching and folding of the tobacco, and the mal-roasted tobacco. The present invention has the advantages of amelioration of the whole set of roasting technics of tobacco, simplification of the roasting stages, thereby greatly decreasing the labor cost involved in the roasting stages. The roasting technics can be doubtless used for roasting the tobacco with the rod-hanging method and the tobacco-nipper method.

Description

technical field [0001] The invention relates to a tobacco leaf curing technology, in particular to a flue-cured tobacco curing process in a loose-leaf intensive curing barn. technical background [0002] The existing flue-cured tobacco curing process mainly refers to the conventional curing process. In recent years, through the test and promotion of intensive curing barns all over the country, the intensive curing technology of flue-cured tobacco has been gradually improved. Since 2002, domestic Heilongjiang, Guizhou, Hubei, Hunan and other places have successively introduced Brazilian loose-leaf barns for testing. The loose-leaf-intensive curing barn is used for baking. Since the baking process is not yet perfect, many places can only use the existing baking technology for baking. After curing, problems such as thin leaves, poor curing rate and bad tobacco often appear, which affect the quality of the tobacco. The popularization and application of loose-leaf intensive bar...
