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
The invention belongs to tobacco storage maintenance technology field, be specifically related to a kind of rich nitrogen hypoxemia sealing storage maintenance process of tobacco leaf.
Background technology
Tobacco leaf is the commodity that a kind of economic worth is higher, it is the important raw material of cigarette industry, but owing to there is defect in various degree after tobacco leaf harvesting baking, as assorted gas weight, flue gas is coarse, cigarette fragrance gas of being mixed is covered, even also have bitter, peppery, the shortcoming such as puckery, so the tobacco leaf after baking should not be directly used in manufacture cigarette, the natural alcoholization that must carry out certain hour in warehouse just can enter Yan Chang and be processed into cigarette, a series of chemical change can be there is in the tobacco leaf of alcoholization phase, assorted gas and excitant are reduced, fragrance increases, color is more even, but tobacco natural alcoholization process needs 2-3, during this period, temperature, humidity, insect pests etc. produce a very large impact tobacco leaf, tobacco leaf can be made to go mouldy, infested, make broken.
Traditional method killing tobacco leaf insect and mould is with phosphine gas (PH
3) stifling, although the method insecticidal effect is obvious, because this insecticides has severe toxicity, inflammable, explosive, in fumigant insect killing process, easily cause poisoning and other the pernicious security incidents of personnel, and have residual in tobacco leaf, bring certain harm also can to surrounding environment and people and animals simultaneously.In addition, the process of the waste gas after fumigating, waste liquid, waste residue is also cumbersome.
At present, seal Ultra Low-oxygen storage (Ultra-lowoxygen, ULO) method to replace hydrogen phosphide method gradually and be widely used in Field of Tobacco.The microorganism that Oxygen control under storage environment can suppress and kill in storage environment by this storage practice below 2% and plant pest.Storage material tobacco leaf can not be polluted in storage, can not environmental pollution be caused, there is the advantage of environmental protection.Such as, but when later stage supplemental oxygen, directly rise to natural environment or higher aerobic environment from less than 2%, quality of tobacco can be caused acutely to become bad, and tobacco leaf darkens after fierce oxidation, can reduce tobacco leaf sucking quality, causes certain economic loss.
Summary of the invention
The present invention is directed to above-mentioned weak point and the rich nitrogen hypoxemia sealing storage maintenance process of a kind of tobacco leaf of providing, in the method, progressively increase oxygen content, can effective disinsection mold-proof and the quality of tobacco leaf in purge process can not be affected.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
A rich nitrogen hypoxemia sealing storage maintenance process for tobacco leaf, comprises the following steps:
(1) tobacco leaf is positioned over seal cavity, utilizes laminated film to seal smoke box and pile up neatly and detect its air-tightness, in smoke box, place wireless Temperature Humidity Sensor and oxygen content sensor simultaneously, gather smoke box humiture and oxygen content information;
(2) condition in sealed cigarette buttress that changes carries out killing pests and suppressing bacteria
After cigarette buttress sealing property reaches requirement, in buttress, be filled with that purity is 98%-99.5%, relative humidity is the nitrogen of 45%-55%, make to reach following requirement in buttress: oxygen concentration is down to 0.1%-2%, relative humidity is 55%-70%, temperature is 15-28 DEG C, maintains this condition 30-45 days;
(3) to after cigarette buttress killing pests and suppressing bacteria, according to tobacco mellowing, curing requirements, the condition in cigarette buttress is adjusted successively, specific as follows:
1. slow down tobacco mellowing speed: oxygen concentration is 2%-5%, relative humidity is 50%-60%, and temperature is 15-28 DEG C, maintains this condition 30-90 days;
2. the alcoholization of tobacco leaf high-quality is newly entered: oxygen concentration is 5%-8%, and relative humidity is 60%-65%, and temperature is 15-28 DEG C, maintains this condition 30-120 days;
3. tobacco mellowing, maintenance store: oxygen concentration is 8%-12%, and relative humidity is 60%-65%, and temperature is 22-25 DEG C, maintains this condition 60-180 days;
4. tobacco leaf normally refines: oxygen concentration is 12%-21%, and relative humidity is 60%-65%, and temperature is 18-28 DEG C, and this condition can reach 24 months by normal storage tobacco leaf.
Further, step (3) is newly entered in tobacco leaf high-quality alcoholization process, and oxygen concentration is 6%.
The rich nitrogen hypoxemia sealing storage maintenance process of a kind of tobacco leaf provided by the invention, has following several beneficial effect:
(1) segmentation increases oxygen content, and controls per stage tobacco leaf to the requirement of oxygen concentration, temperature and humidity, can effective disinsection mold-proof and can not affect the quality of tobacco leaf in alcoholization process.
(2) monitored by wireless senser, can monitor the inner oxygen content of tobacco leaf and humiture in real time, this process does not need to open sealing device, reduces the probability that cigarette buttress is infested and go mouldy.
(3) this process desinsection speed is fast, can not work the mischief to environment and surrounding people and animals.
