Embodiment 1

[0020] A comb-type tobacco clip baking process, the tobacco leaves are evenly loaded on the comb-type tobacco clips, the amount of smoke in each comb-type tobacco clip is 12.5Kg, and the number of tobacco clips per room is 360, including the following steps :

[0021] The first step, the preheating stage: put the tobacco leaves evenly on the comb-type tobacco clips and pack them tightly into the barn, quickly raise the temperature in the barn to 36°C after ignition, and adjust the target value of the wet bulb temperature to 36°C , the fan speed is 940r / min, bake at a steady temperature for 12 hours, so that the tip of the blade in the high temperature layer is soft;

[0022] The second step, moisturizing and yellowing period: raise the dry bulb temperature to 38°C at a heating rate of 1°C / h, control the wet bulb temperature to 37°C, and bake at a steady temperature for 24 hours. When the middle tobacco leaves are 50% yellow At this stage, lower the wet bulb temperature by 0.5...

Embodiment 2

[0031] A baking process for comb-type tobacco clips. Tobacco leaves are evenly loaded on the comb-type tobacco clips. The amount of tobacco loaded in each comb-type tobacco clip is 13Kg, and the number of tobacco clips in one room is 350. It includes the following steps:

[0032] The first step, the preheating stage: put the tobacco leaves evenly on the comb-type tobacco clips and pack them tightly into the barn, quickly raise the temperature in the barn to 36°C after ignition, and adjust the target value of the wet bulb temperature to 36°C , the fan speed is 950min, and the temperature is stable and baked for 10h, so that the tip of the blade in the high temperature layer is soft;

[0033] The second step, moisturizing and yellowing period: raise the dry bulb temperature to 39°C at a heating rate of 1°C / h, control the wet bulb temperature to 37°C, and bake at a steady temperature for 26 hours. When yellowing, reduce the wet bulb temperature by 0.5°C and perform a small amount...

Embodiment 3

[0042] A baking process for comb-type tobacco clips. Tobacco leaves are evenly loaded on the comb-type tobacco clips. The amount of tobacco loaded in each comb-type tobacco clip is 14Kg, and the number of tobacco clips in one room is 340. It includes the following steps:

[0043] The first step, the preheating stage: put the tobacco leaves evenly on the comb-type tobacco clips and pack them tightly into the barn, quickly raise the temperature in the barn to 36°C after ignition, and adjust the target value of the wet bulb temperature to 36°C , the fan speed is 960r / min, bake at a steady temperature for 12 hours, so that the tip of the blade in the high temperature layer is soft;

[0044] The second step, moisturizing and yellowing period: at a heating rate of 1°C / h, raise the dry bulb temperature to 38°C, control the wet bulb temperature to 37°C, and bake at a steady temperature for 28 hours. When the middle tobacco leaves are 60% yellow At this stage, the wet bulb temperature ...

Abstract

The invention discloses a baking process of comb-type tobacco clamps. Tobaccos are evenly arranged on the comb-type tobacco clamps, and the comb-type tobacco clamps are closely arranged inside a baking room. According to change degrees of the tobaccos, baking periods are divided into a preheating period, a moisture-preserving yellow-turning period, a temperature raising period between the moisture-preserving yellow-turning period and a moisture-discharging yellow-turning period, the moisture-discharging yellow-turning period, a temperature raising period between the moisture-discharging yellow-turning period and a moisture-discharging color-fixing period, the moisture-discharging color-fixing period, a temperature raising period between the moisture-discharging color-fixing period and a moisture-preserving color-fixing period, the moisture-preserving color-fixing period and a rib drying period. According to the baking process, various process parameters in the baking process are determined, two key periods, including the yellow-turning period and the color-fixing period, in the baking process are detailed, the high operability is achieved, the quality of the tobaccos can be obviously improved, the braking difficulty can be reduced, and therefore tobacco growers can easily master and accept the baking process.

Description

technical field [0001] The invention discloses a curing process of flue-cured tobacco, which belongs to the technical field of tobacco leaf curing. Background technique [0002] In the process of flue-cured tobacco production, the quality of flue-cured tobacco is mainly affected by the quality of field fresh tobacco and the level of curing. When the quality of field fresh tobacco is determined, the importance of baking factors becomes more important. Tobacco planting in my country is developing in the direction of scale, and the planting area is relatively concentrated and large, so there are corresponding curing barns. However, the number of barns in the barn group is relatively limited. How to use the limited barns to roast more tobacco leaves can only increase the amount of tobacco in a single barn, so dense barns appear. The tobacco loading methods in dense barns mainly include comb-type tobacco clips, loose leaf insertion, loose leaf accumulation, cage tobacco clips, ...
