Embodiment 1

[0024] A method for shortening the curing time of tobacco leaves in an airtight curing room. The upper leaves (4-6 leaves in the upper part) of K326 are used as the test materials, the sundries are removed, cigarettes are classified into cigarettes, and cigarettes are loaded, and the tobacco leaves with the same maturity are placed in the same Baking in the oven. The airtight heat pump barn is provided by Yunnan Zhonghai Luther Clean Technology Co., Ltd. The airtight heat pump barn has no moisture and heat exhaust ports, and the excess water is removed by the equipment in the form of condensed water. The size of the smoke chamber is 8.0m×2.7m× 3.5m, 2 roads and 3 floors. In the early stage of yellowing for 0-12 hours, fill with 1.2% oxygen, in the middle and late stages of yellowing (i.e. start baking for 13-85 hours, preferably start baking for 45-72 hours), fill in 1.5% carbon dioxide, and in the later stage of color fixing to dry tendons 0.5% carbon dioxide is charged duri...

Embodiment 2

[0036] The upper leaves of Yunyan 87 (4-6 leaves in the upper part) were used as the test materials, the sundries were removed, the tobacco was classified into cigarettes, and the tobacco leaves with the same maturity were placed in the same roasting room for curing. The airtight heat pump barn is provided by Yunnan Zhonghai Lude Clean Technology Co., Ltd. The specifications of the barn are 8.0m×2.7m×3.5m, with 2 channels and 3 floors. In the early stage of yellowing for 0-12 hours, fill with 1.0% oxygen, in the middle and late stages of yellowing (that is, start baking for 13-85 hours, preferably start baking for 45-72 hours), fill in 1.2% carbon dioxide, and in the later stage of color fixing to dry tendons 0.5% carbon dioxide is charged during the period (ie, 86-176 hours after the start of baking, preferably 96-116 hours after the start of baking). Compared with the traditional dense curing room tobacco curing and the existing closed heat pump curing technology.

Embodiment 3

[0049]The middle leaves of K326 (the 10th to 12th tobacco leaves in the middle) were used as the test material, the sundries were removed, the tobacco was classified into cigarettes, and the tobacco leaves with the same maturity were placed in the same roasting room for curing. The airtight heat pump barn is provided by Yunnan Zhonghai Lude Clean Technology Co., Ltd. The specifications of the barn are 8.0m×2.7m×3.5m, with 2 channels and 3 floors. In the early stage of yellowing for 0-12 hours, fill in 0.8% carbon dioxide, in the middle and late stage of yellowing (i.e. start baking for 13-85 hours, preferably start baking for 45-72 hours), fill in 1.0% carbon dioxide, and in the later stage of color fixing to dry gluten 0.3% carbon dioxide is charged during the period (ie, 86-176 hours after the start of baking, preferably 96-116 hours after the start of baking). Compared with the traditional dense curing room tobacco curing and the existing closed heat pump curing technology....

Abstract

The invention discloses a method for shortening the tobacco leaf baking time of a closed barking room, belonging to the technical field of modulation of flue-cured tobacco. The method comprises the following steps: manually introducing oxygen in the front yellowing stage, so as to maintain the oxygen concentration in the closed barking room at 0.5%-2.0%; manually introducing carbon dioxide from the middle-later yellowing stage to a color fixation stage, so as to maintain the carbon dioxide concentration in the closed barking room at 0.5%-2.0%; and continuing to introduce carbon dioxide from alater color fixation stage to a tendon drying stage, so as to maintain the carbon dioxide concentration in the closed barking room at 0.1%-0.8%. The method has the beneficial effects that the respiratory action of tobacco leaves in the baking process can be adjusted, the baking time can be shortened, the quality of the tobacco leave can be improved, the utilization rate of the baking room can be increased, the energy consumption cost can be lowered, and the increase of farmer's income can be promoted.

Description

technical field [0001] The invention relates to the technical field of flue-cured tobacco preparation, in particular to a method for shortening the curing time of tobacco leaves in an airtight curing room. Background technique [0002] Curing and modulation is an important link in the production process of flue-cured tobacco. The quality of curing results is directly related to the quality of tobacco leaves and the income of tobacco farmers. With the development of science and technology, a clean baking technology came into being - closed heat pump baking room. After field trials and promotion and application verification, the technology has the advantages of saving labor and reducing costs, energy saving and emission reduction, and improving quality and flavor. [0003] In terms of structure, the main feature of this technology is that there is no moisture and heat exhaust port in the oven, and the excess moisture is removed in the form of condensed water through the equip...
