Embodiment 1

[0027] 1. Fill high-purity nitrogen into the sealed stack to reduce the oxygen concentration in the sealed stack to below 2% and maintain it, and ensure that the ambient oxygen concentration in the sealed stack is always in low oxygen through daily nitrogen supplementation and other control operations state;

[0028] 2. Fill the space with ozone with a concentration of 20-99ppm. The frequency of the introduction of ozone gradually decreases from the first stage to the third stage, wherein the first stage is treated for 7-10 days, the second stage is treated for 11-20 days, and the third stage is the second stage after. In the first stage, treat 4-5 times a day, in the second stage, 2-3 times a day, and in the third stage, 1-2 times a day. It should be noted that at this stage, nitrogen will be filled to reduce the oxygen concentration in the sealed stack to below 2% and maintain it, the same below.

Embodiment 2

[0030] 1. Fill high-purity nitrogen into the sealed stack to reduce the oxygen concentration in the sealed stack to below 2% and maintain it, and ensure that the ambient oxygen concentration in the sealed stack is always in low oxygen through daily nitrogen supplementation and other control operations state;

[0031] 2. Fill the space with ozone with a concentration of 100-200ppm. The frequency of the introduction of ozone gradually decreases from the first stage to the third stage, wherein the first stage is treated for 7-10 days, the second stage is treated for 11-20 days, and the third stage is the second stage after. In the first stage, treat 4-5 times a day, in the second stage, 2-3 times a day, and in the third stage, 1-2 times a day.

Embodiment 3

[0033] 1. Fill high-purity nitrogen into the sealed stack to reduce the oxygen concentration in the sealed stack to below 2% and maintain it, and ensure that the ambient oxygen concentration in the sealed stack is always in low oxygen through daily nitrogen supplementation and other control operations state;

[0034] 2. Fill the space with ozone at a concentration of 201-300ppm. The frequency of the introduction of ozone gradually decreases from the first stage to the third stage, wherein the first stage is treated for 7-10 days, the second stage is treated for 11-20 days, and the third stage is the second stage after. In the first stage, treat 4-5 times a day, in the second stage, 2-3 times a day, and in the third stage, 1-2 times a day.

Abstract

The invention discloses a mould removal processing method for alcoholizing expired mouldy tobacco leaves; the method comprises the following steps: filling sealed tobacco stacks with nitrogen and keeping a low-oxygen environment, wherein by filling the nitrogen, oxygen concentration in the sealed tobacco stacks finally drops to 2% and below and is kept at the level; and filling the sealed tobaccostacks with ozone to process moulding, wherein ozone concentration is 20-500ppm, and frequency of filling the ozone is gradually reduced from the first stage to the third stage, wherein the first stage is implemented at 7-10 days, the second stage lasts from the 11 day to the 20 day, and the third stage is implemented after the second stage. With the application of the method, suchproblems that wind mould appears on the surfaces of tobacco leaves in a storage and care process of the tobacco leaves and the like can be effectively solved, and flavor and smoking taste of mouldy tobacco leaves can be guaranteed; the tobacco leaves, which become to be yellow from brown, are presented in ideal color; and therefore, a using rate of the mouldy tobacco leaves is increased, and tobacco loss and economic loss, which are caused by the mouldy tobacco leaves, are reduced.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for removing mildew from moldy tobacco leaves after aging. 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 frequently. According ...
