Abstract
The invention discloses a tobacco mildew-proof method for ethanol slow-release sterilization. Mixing waste tobacco powder and absolute alcohol according to the ratio of 2-4: 1, the mixture is packaged by a breathable bag to be used as a mildew preventive and is respectively placed in the center and the periphery of a tobacco pile, and the weight ratio of the mildew preventive to tobacco leaves is 1-2: 100. slowly releasing ethanol steam at fixed points in the sealed tobacco pile, so that the tobacco leaves are in the atmosphere containing the ethanol steam for a long time to inhibit or kill putrefying bacteria. The invention improves the safety of alcohol use and the alcohol sterilization efficiency, shortens the tobacco processing time and has simple and convenient operation process.
Description
Technical field
The invention belongs to technical field of cigarette processing, be specifically related to the tobacco leaf mold-proof method of a kind of ethanol slowly-releasing sterilization.
Background technology
Tobacco leaf before for production of cigarettes, needs through the storage of 1 ~ 3 year, alcoholization process, and object is to improve quality of tobacco by alcoholization.Because tobacco leaf hygroscopicity is strong, and containing the various nutriments required for growth of microorganism, very easily grow various microorganism in alcoholization phase or lay up period and make tobacco leaf moldy metamorphism, thus had a strong impact on presentation quality and the organoleptic quality of tobacco leaf, reduce the use value of tobacco leaf, especially all the more so in humidity, summer that temperature is high.Tobacco mildew, as the global problem of tobacco, causes massive losses to enterprise and country, is day by day subject to people's attention.
Tobacco mildew main cause is mould growth and breeding on tobacco leaf.The condition of mould breeding has three: nutrition, temperature, humidity.Owing to containing the abundant organic substance such as sugar, protein in tobacco leaf, be the basis of fungus growth breeding, through a series of processes such as just roasting, classification, purchase and packagings, surface and inside have posted a large amount of microorganism attached, under the condition of, high humidity high in temperature, the easiest moisture absorption of tobacco leaf is mouldy.And in hot and humid air, the speed that tobacco leaf absorbs moisture is accelerated further, more the growth and breeding of mould creates favourable condition.Present stage, controlling and preventing the technical measures taked in tobacco mildew from mainly containing two kinds of approach both at home and abroad.One is thoroughly killed by tobacco leaf pathogenic microorganism, and as adopted 60Co-Y ray tobacco leaf irradiation, tobacco leaf is fumigated (as hydrogen phosphide, oxirane and ozone etc.) and reached the object of mildew and insect proof with chemical biocide etc.; Another kind is the water content by controlling tobacco leaf, the temperature of storage environment, humidity and oxygen concentration, and add chemistry and the biological growth pressing down raw agent and suppress causal organism, reach the object delaying tobacco mildew process, as tobacco leaf controlled atmosphere storage (being filled with nitrogen and carbon dioxide), sealed oxygen-reducing (seal or add deoxidier etc. simultaneously).Although these measures serve certain effect to minimizing tobacco mildew, be difficult to reach desirable prevention effect.Control the temperature in storage environment, humidity is very high to the requirement of storehouse, a large amount of conditioning equipment is installed, and a large amount of electric energy will be consumed, there is the defects such as weak effect, investment is large, operating cost is high; Sprinkling is even and comprehensively, thus limited efficiency, is also difficult to the harmful effect avoiding chemical agent to cause environment and food in addition to use chemical agent to be difficult to; Sealed oxygen-reducing requires higher to construction material, so involve great expense, storage cost is high.
Ethanol is commonly called as alcohol, and molecular formula is C
2h
5oH (C
2h
6o), be a kind of inflammable, volatile colourless transparent liquid under normal temperature, normal pressure, its solution has special, pleasant fragrance, and slightly excitant.Having many uses of ethanol, available ethanol manufactures acetic acid, beverage, essence, dyestuff, fuel etc.Ethanol is a kind of conventional disinfection sanitizer in daily life, and it, by infiltrating in bacterial body, absorbs the moisture of bacterioprotein, make the protein coagulating of composition bacterium, cause sex change and the precipitation of protein, thus reach the object of kill bacteria.Because ethanol is liquid, volatile, burning, is therefore only limitted to use in the daily lifes such as medical treatment as disinfection sanitizer, and utilizes ethanol to there is not yet reported success at home and abroad to prevent the method for tobacco mildew.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, utilize the bactericidal property of ethanol, for tobacco leaf storage provides the tobacco leaf mold-proof method of a kind of pollution-free, noresidue, safety, environmental protection.
Object of the present invention is achieved by the following technical programs.
Except as otherwise noted, percentage of the present invention is percetage by weight.
The tobacco leaf mold-proof method of a kind of ethanol slowly-releasing sterilization, it is characterized in that: waste tobacco powder is mixed with the weight ratio of absolute alcohol by 2 ~ 4:1, mixture venting bags installs as mould inhibitor, and be placed in Yan Duo center and surrounding, and the weight proportion of mould inhibitor and tobacco leaf is 1 ~ 2:100.
The preferred weight ratio of waste tobacco powder and absolute alcohol is 3:1.
Mould inhibitor adopts uniform mode to place.
When placing mould inhibitor, the amount ratio of Yan Duo center and surrounding is 1:2.
When placing mould inhibitor, the amount ratio that cigarette is stamped towards sunny side and in the shade is 1:7.
The composite membrane that preferred employing is closed or closed chamber Storage tobacco.
Relative to prior art, the present invention has the following advantages:
1, alcohol has fungicidal spectrum extensively, efficiently, pollution-free, the features such as use cost is low.To realizing the clean storage of tobacco leaf, push forward safety in production comprehensively significant.
2, alcohol is volatilizable gas, and in sealed cigarette is stamped, permeability is strong, and diffusivity is good, and even concentration does not have dead angle.
3, the present invention uses waste tobacco powder to adsorb fixing alcohol, make the sterilization of alcohol slow releasing, long for the tobacco leaf storage cycle, environmental change is complicated, existing method can not realize the deficiency of permanently effective control tobacco mildew, improve security and the alcohol germicidal efficiency of alcohol use, shorten the tobacco leaf processing time, operating process is simple and convenient.
