Problems solved by technology

However, when oxygen is supplemented in the later stage, directly rising from below 2% to a natural environment or a higher oxygen-containing environment will cause the quality of the tobacco leaves to deteriorate drastically. For example, the color of the tobacco leaves will become darker after intense oxidation, which will reduce the smoking quality of the tobacco leaves. cause some economic loss

[0021] Example 1 Take 100 boxes of tobacco leaves with some insects as an example

[0022] A nitrogen-enriched and low-oxygen sealed storage and maintenance method for tobacco leaves, comprising the following steps:

[0023] (1) Place the tobacco leaves in a sealed space, use a composite film to seal the stack of cigarette boxes and detect its air tightness, and place a wireless temperature and humidity sensor and an oxygen content sensor in the smoke box to collect the temperature, humidity and oxygen content of the smoke box information;

[0024] (2) Change the conditions in the sealed stack to kill insects and inhibit bacteria

[0025] After the sealing performance of the stack meets the requirements, fill the stack with nitrogen with a purity of 98%-99.5% and a relative humidity of 45%-55%, so that the stack can meet the following requirements: the oxygen concentration is reduced to 0.1%, and the relative humidity is 55% %, the temperature is 15°C, and this condition is ...

Abstract

The invention discloses a nitrogen-rich and low-oxygen sealed storage maintenance method of tobacco leaves. The method includes the following steps of firstly, putting tobacco leaves in a sealed space, sealing a tobacco box stack with a compound thin film, and installing a wireless sensor; secondly, decreasing the O2 concentration to be 0.1-2%, and keeping the relative humidity being 55-70% and the temperature being 15-28 DEG C for 30-45 days; thirdly, sequentially adjusting the conditions in the tobacco stack, wherein the O2 concentration is 2-5%, the relative humidity is 50-60%, and the temperature is 15-28 DEG C; the O2 concentration is 5-8%, the relative humidity is 60-65%, and the temperature is 15-28 DEG C; the O2 concentration is 8-12%, the relative humidity is 60-65%, and the temperature is 22-25 DEG C; the O2 concentration is 12-21%, the relative humidity is 60-65%, and the temperature is 18-28 DEG C. By means of the method, the oxygen content is increased in a segmented mode, insecticidal and mould-proof effects can be effectively achieved, and the quality of tobacco leaves in the alcoholization process can not be influenced.

Description

technical field [0001] The invention belongs to the technical field of tobacco storage and maintenance, and in particular relates to a nitrogen-enriched and low-oxygen sealed storage and maintenance method for tobacco leaves. Background technique [0002] Tobacco leaf is a commodity with high economic value and an important raw material for the cigarette industry. However, due to the defects of varying degrees after harvesting and roasting tobacco leaves, such as heavy miscellaneous gas, rough smoke, smoke flavor covered by miscellaneous gas, and even Bitter, spicy, astringent and other disadvantages, so the tobacco leaves after roasting should not be directly used to make cigarettes. They must be naturally aged in the warehouse for a certain period of time before they can be processed into cigarettes in the tobacco factory. A series of chemical reactions will occur in the tobacco leaves during the aging period. Changes can reduce the miscellaneous gas and irritation, increa...
