Embodiment 1

[0021] First of all, operate the tobacco clip loading process on the operating table to ensure that the quality of tobacco leaves in the same clip and the same curing room is consistent. During the loading process, ensure that the tobacco leaves are evacuated and evenly distributed on the tobacco clip, and the leaf bases are aligned. The effective width of cigarettes is 8cm, the weight of each cigarette is 12.5kg, and the amount of cigarettes in each room is 4500kg. After hanging in the barn, perform the following special flue-cured tobacco steps in sequence:

[0022] (1) Moisturizing and yellowing period: install the cigarette in the barn with a density of 60Kg / m 3 , forcibly close the moisture exhaust window, and then ignite the temperature at a heating rate of 1 ℃ / h to 35-36 ℃ (dry bulb temperature), stabilize the temperature for 20 hours, until the tobacco leaves in the low temperature layer become 50% yellow; this step is set first after ignition The fan (No. 7 standard ...

Embodiment 2

[0033] First of all, operate the tobacco clip loading process on the operating table to ensure that the quality of tobacco leaves in the same clip and the same curing room is consistent. During the loading process, ensure that the tobacco leaves are evacuated and evenly distributed on the tobacco clip, and the leaf bases are aligned. The effective width of cigarettes is 8cm, the weight of each cigarette is 13.5kg, and the amount of cigarettes in each room is 4700kg. After hanging in the barn, perform the following special flue-cured tobacco steps in sequence:

[0034] (1) Moisturizing and yellowing period: put the cigarette clips in the barn with a density of 55Kg / m 3 , forcibly close the moisture exhaust window, and then ignite the temperature at a heating rate of 1 ℃ / h to 35-36 ℃ (dry bulb temperature), stabilize the temperature for 22 hours, until the tobacco leaves in the low temperature layer become 50% yellow; this step is set first after ignition The fan (No. 7 standar...

Embodiment 3

[0044]First of all, operate the tobacco clip loading process on the operating table to ensure that the quality of tobacco leaves in the same clip and the same curing room is consistent. During the loading process, ensure that the tobacco leaves are evacuated and evenly distributed on the tobacco clip, and the leaf bases are aligned. The effective width of cigarettes is 8cm, the weight of each cigarette is 15kg, and the amount of cigarettes in each room is 5000kg. After hanging in the barn, perform the following special flue-cured tobacco steps in sequence:

[0045] (1) Moisturizing and yellowing period: put the cigarette clips in the barn with a density of 55Kg / m 3 , forcibly close the moisture exhaust window, and then ignite the temperature at a heating rate of 1 ℃ / h to 35-36 ℃ (dry bulb temperature), stabilize the temperature for 20 hours, until the tobacco leaves in the low temperature layer become 50% yellow; this step is set first after ignition The fan (No. 7 standard f...

Abstract

The invention belongs to the technical field of tobacco curing, and particularly relates to a special tobacco curing method used for a tobacco clamp packing mode in a bulk curing barn. The special tobacco curing method mainly includes a yellowing stage, a quick color fixing stage and a stem drying stage, wherein the yellowing stage comprises a moisture maintenance yellowing stage, a medium-moisture yellowing stage and a moisture eliminating yellowing stage; the quick color fixing stage comprises two temperature rising stages and a temperature stabilizing and color fixing stage. Process parameters in all stages of the curing process are made clear, indexes are clear, operations are easy and convenient, the difficult problems that tobacco leaves cannot become yellow sufficiently in a current production process and the color fixing process cannot be accurately controlled are solved, the technical difficulty of curing is further reduced and the method is convenient to master, use and widely popularize.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf curing, and in particular relates to a special flue-curing method for densely-cured tobacco in the way of sandwiching tobacco. Background technique [0002] In my country's national economy, the status of tobacco is very important. In many areas, tobacco is an important source of fiscal revenue. In the production process of tobacco leaves, varieties and cultivation techniques are the basis for determining the quality of fresh tobacco, and there are many other controlled factors, especially environmental factors. Curing is the last link in tobacco production, and it is the link most affected by human factors in tobacco production, so it is a key stage in tobacco production. [0003] With the rapid development of modern tobacco agriculture, large-scale tobacco planting has given birth to the emergence of intensive curing rooms. Limited by the number of curing rooms, a method of filling cigaret...
