Abstract
The invention provides a kind of tobacco leaf storage alcoholization control oxygen disinsection mold-proof method, comprise following steps: (1) oxygen concentration is down to and is less than 2%: tobacco leaf is positioned over seal cavity, use nitrogen making machine oxygen concentration in seal cavity to be down to and be less than 2%, maintain this concentration 20-40 days; (2) substep improves oxygen concentration to 15%: use oxygenating equipment to be filled with air and oxygen concentration substep in seal cavity is increased to 15%.Killing tobacco pests of the present invention and mould are thorough rapidly, and the quality of complete no effect on tobacco mellowing.
Description
Technical field
The invention belongs to tobacco storage maintenance technology field, relate to a kind of tobacco leaf storage alcoholization control oxygen disinsection mold-proof method.
Background technology
Strict requirement is had in tobacco manufacture field, the particularly cigarette industry quality to raw tobacco material.Because there is defect in various degree after tobacco leaf harvesting baking, as assorted gas is heavy, flue gas is coarse, cigarette fragrance is mixed, and gas is covered, even also have the shortcomings such as bitter, peppery, puckery, so the tobacco leaf after baking should not be directly used in manufacture cigarette, must natural alcoholization process be carried out.Can be there is a series of chemical change in the tobacco leaf of alcoholization phase, assorted gas and excitant are reduced, and fragrance increases, inhale taste alcohol and, color is more even.The tobacco mellowing time is generally 1-3.
Mildew, the phenomenon such as infested is easily there is in tobacco mellowing process, all the more so in damp and hot south.Traditional method killing tobacco leaf insect and mould is fumigated with phosphine gas, but hydrogen phosphide is hypertoxic and inflammable and explosive, easily damages to producers, and has residual in tobacco leaf.At present, seal Ultra Low-oxygen storage (Ultra-low oxygen, 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.
Simple use sealing Ultra Low-oxygen storage practice, as fallen oxygen desinsection sealing compound etc., make tobacco leaf be in the low-oxygen environment of less than 2% for a long time, excessively reducing tobacco mellowing speed, easily there is darkening phenomenon in tobacco leaf, and aesthetic quality declines.Oxygen concentration is better about 6% tobacco mellowing aesthetic quality.Therefore need to regulate and control oxygen, tobacco mellowing beforehand control oxygen concentration, below 2%, guarantees disinsection mold-proof effect, and the later stage is suitably heightened in tobacco leaf stack about oxygen concentration to 6%, while desinsection, creates a kind of environment favourable to tobacco mellowing.
Chinese Patent Application No.: 200810238964.4 disinsection mold-proof methods disclosing a kind of no effect on tobacco mellowing, be divided into two steps: the first step adopts oxygen-absorbing material or the oxygen concentration percent by volume stored in sealing bag is reduced to 0.01-4% by tobacco leaf with nitrogen, carbon dioxide or inert gas, sealing 10-400 days; Second step is toward supplemental oxygen or air in tobacco leaf sealing bag, and make the oxygen concentration percent by volume in bag rise to 4-40%, the storage time is 10-700 days.The method does not disclose the concrete operation method falling oxygen and supplemental oxygen, and people cannot be operated according to the method for document introduction.In addition, when the supplemental oxygen in later stage, if risen to suddenly natural environment or higher aerobic environment from less than 2%, can cause quality of tobacco and acutely become bad, oxidation color as fierce in tobacco leaf is deepened, and reduces tobacco leaf sucking quality.
Summary of the invention
Technical problem to be solved by this invention is for the above-mentioned deficiency existing for prior art, provides a kind of tobacco leaf storage to refine control oxygen disinsection mold-proof method, and its disinsection mold-proof is effective, the capability and performance that do not affect tobacco leaf in alcoholization process.
In order to solve the problem, the technical solution adopted in the present invention is that this tobacco leaf storage alcoholization control oxygen disinsection mold-proof method comprises the following steps: (1) oxygen concentration is down to and is less than 2%: tobacco leaf is positioned over seal cavity, use nitrogen making machine oxygen concentration in seal cavity to be down to and be less than 2%, maintain this concentration 20-40 days; (2) substep improves oxygen concentration to 15%: use oxygenating equipment to be filled with air and oxygen concentration substep in seal cavity is increased to 15%.
Preferably, described substep improves oxygen concentration to 15% required time is 70-1155 days.
Preferably, described substep improves oxygen concentration and first oxygen concentration is risen to 2-6% from being less than 2%, and maintains this concentration 10-15 days.
Preferably, described substep improves oxygen concentration and oxygen concentration is risen to 6-10% from 2-6%, and maintains this concentration 1-36 month.
Preferably, described substep improves oxygen concentration and oxygen concentration is risen to 10-15% from 6-10%, and maintains this concentration 1-2 month.
The present invention adopts storage condition when dividing step-up oxygen control tobacco mellowing.This tobacco leaf storage alcoholization initial stage adopts the air in nitrogen making machine Rapid replacement seal cavity, reaches the object of falling oxygen, progressively regulates and controls oxygen concentration in seal cavity after keeping low oxygen concentration a period of time killing tobacco pests and mould with oxygenating equipment again.
Chinese patent CN201541699U describes oxygenating oxygen increasing equipment after a kind of sealed oxygen-reducing pest killing of tobacco, sealed cigarette buttress is provided with outlet pipe and air inlet pipeline, outlet pipe is provided with solenoid electric valve of giving vent to anger, air inlet pipeline is provided with air inlet solenoid electric valve, oxygen detection instrument in sealed cigarette buttress is electrically connected with the input of transducer controller, the output of transducer controller and solenoid electric valve of giving vent to anger, air inlet solenoid electric valve and high pressure positive blower electricly connect, high pressure positive blower is connected with purification of air drying machine entrance point, the purification of air drying machine port of export is connected with air inlet pipeline.The present invention utilizes this equipment as oxygenating equipment, oxygen content in regulation and control tobacco mellowing stage seal cavity.
After oxygen falls in step (1), in seal cavity, tobacco-plant pest-insect and mould are killed completely, and step (2) progressively improves oxygen content in seal cavity.Because oxygen concentration is better about 6% tobacco mellowing aesthetic quality, in step (2), 2-6% and 6-10% phase duration is the longest, and the concrete time determines according to tobacco mellowing situation, makes tobacco-alcoholizing quality reach best.
Preferably, described nitrogen making machine comprises system with molecular sieve for preparing nitrogen machine and membrane separation nitrogen making machine, and gas production is at 20m
3/ more than h, nitrogen gas purity of producing is more than 98%.
Use method of the present invention can realize following advantage:
1. killing tobacco pests and mould speed are soon, and without any pollution;
2. solve in prior art to use and fall oxygen desinsection sealing compound and fall oxygen slowly and affect the problem of tobacco-alcoholizing quality.
The inventive method also may be used for the material that preservation Chinese medicine, grain, seed, fruit etc. need to carry out storing in a warehouse.
