Problems solved by technology

[0007] The purpose of the present invention is to overcome the defects of the prior art and provide a method for removing mildew from mildewed tobacco leaves during the alcoholization period. This method effectively solves the problems of mildew on the surface of tobacco leaves during the storage and maintenance of tobacco leaves without affecting the normal aging of tobacco leaves. And realize the maintenance of the flavor and taste of mildewed tobacco leaves; make the tobacco leaves present an ideal color, increase the utilization rate of moldy tobacco leaves, and reduce the loss of tobacco leaves and economic losses caused by mildewed tobacco leaves

Embodiment 1

[0031] 1. The first stage: inject ozone with a concentration of 20-99ppm into the sealed stack every day, and treat it for 10-30 days;

[0032] 2. The second stage: Introduce ozone with a concentration of 10-50ppm until the alcoholization period ends;

[0033] 3. The third stage: from the end of the alcoholization period to the stage of tobacco leaf opening and use, nitrogen and ozone are introduced at the same time, and the nitrogen gas introduced finally reduces the oxygen concentration in the sealed tobacco leaf stack to below 2%. The concentration of ozone is 1-10ppm.

Embodiment 2

[0035] 1. The first stage: inject ozone with a concentration of 100-200ppm into the sealed stack every day, and treat it for 10-30 days;

[0036] 2. The second stage: Introduce ozone with a concentration of 10-50ppm until the alcoholization period ends;

[0037] 3. At the stage from the end of the alcoholization period to the opening of the tobacco leaves for use, nitrogen and ozone are simultaneously introduced, and the nitrogen gas introduced finally reduces the oxygen concentration in the sealed tobacco leaf stack to below 2%, and the concentration of the ozone introduced is 1-10ppm.

Embodiment 3

[0039]1. The first stage: inject ozone with a concentration of 201-300ppm into the sealed stack every day, and treat it for 10-30 days;

[0040] 2. The second stage: Introduce ozone with a concentration of 10-50ppm until the alcoholization period ends;

[0041] 3. At the stage from the end of the alcoholization period to the opening of the tobacco leaves for use, nitrogen and ozone are simultaneously introduced, and the nitrogen gas introduced finally reduces the oxygen concentration in the sealed tobacco leaf stack to below 2%, and the concentration of the ozone introduced is 1-10ppm.

Abstract

The invention discloses a mildew-removing treatment method for moldy tobacco leaves in the alcoholization period. Ozone is passed into the sealed tobacco leaf stack to treat mildew. The ozone treatment is divided into two stages: the first stage is the daily ozone concentration of 20-500ppm, Treat for 10-30 days; in the second stage, an ozone concentration of 5-100ppm is introduced until the end of the alcoholization period of the tobacco leaves; Finally, the oxygen concentration in the sealed tobacco leaf stack is reduced to below 2%, and the concentration of the ozone introduced is 1-10ppm; this method effectively solves the problems such as mildew on the surface of the tobacco leaves during the storage and maintenance of the tobacco leaves in the aging period, without affecting Tobacco leaves are aged normally, and the aroma and taste of mildewed tobacco leaves are maintained; the tobacco leaves present an ideal color, increase the utilization rate of mildewed tobacco leaves, and reduce the loss of tobacco leaves and economic losses caused by mildewed tobacco leaves.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for removing mildew from mildewed tobacco leaves during the aging period. Background technique [0002] At present, in the tobacco industry, mildew of tobacco leaves is one of the main factors affecting the quality of tobacco leaves, and it will also cause huge economic losses. In the Yangtze River Basin and South China, due to the year-round high-temperature and high-humidity climate environment and the relatively backward conditions of some tobacco leaf storage warehouses, tobacco leaves are prone to mildew, which brings great difficulties to the maintenance of tobacco leaves. Traditional anti-mildew measures for tobacco leaves often focus on reducing temperature and humidity or reducing oxygen content, etc., but once the tobacco leaves become moldy, the use value will be greatly reduced or even scrapped. Mildew of stored tobacco leaves still occurs frequen...
