Abstract
The invention provides a method for killing injurious insects and preventing mildew in the storage and mellowing processes of tobaccos by controlling oxygen. The method comprises the following steps of: (1) reducing the concentration of oxygen until the concentration is less than 2 percent, namely putting the tobaccos into hermetic space, reducing the concentration of the oxygen in the hermetic space until the concentration is less than 2 percent by using a nitrogen making machine, and maintaining the concentration for 20 to 40 days; and (2) improving the concentration of the oxygen step by step until the concentration is 15 percent, namely introducing air by using oxygen compensating equipment, and improving the concentration of the oxygen in the hermetic space to be 15 percent step by step. By the method, the injurious insects and mold of the tobaccos can be killed quickly and completely, and the mellowing quality of the tobaccos is not influenced completely.
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
At tobacco manufacture field, particularly cigarette industry the quality of raw tobacco material there is strict requirement.Because there is in various degree defective, heavy such as assorted gas, flue gas is coarse, cigarette fragrance is mixed, and gas is covered after the tobacco leaf harvesting baking, even also have the shortcomings such as bitter, peppery, puckery, so the tobacco leaf after the baking should not be directly used in the manufacturing cigarette, must carry out the natural alcoholization processing.A series of chemical change can occur in the tobacco leaf of alcoholization phase, and assorted gas and excitant are reduced, and fragrance increases, and it is pure and mild to inhale flavor, and color is more even.The tobacco mellowing time is generally 1-3.
Mildew, the phenomenon such as infested appear in the tobacco mellowing process easily, damp and hot southern all the more so.Traditional method of killing tobacco leaf insect and mould is stifling with phosphine gas, but hydrogen phosphide severe toxicity and inflammable and explosive damages to producers easily, and has residual in tobacco leaf.At present, sealing Ultra Low-oxygen storage (Ultra-low oxygen, ULO) method replaces gradually the hydrogen phosphide method and is widely used in Field of Tobacco.This storage practice with the Oxygen control under the storage environment at microorganism and the plant pest that can suppress and kill below 2% in the storage environment.Can not pollute storage material tobacco leaf in the storage, can not cause environmental pollution, have the advantage of environmental protection.
Simple use sealing Ultra Low-oxygen storage practice, as fall oxygen desinsection sealing compound etc., make tobacco leaf be in for a long time low-oxygen environment 2% below, excessively reduce tobacco mellowing speed, tobacco leaf is prone to the phenomenon that darkens, aesthetic quality's decline.Oxygen concentration is better 6% left and right sides tobacco mellowing aesthetic quality.Therefore need to regulate and control oxygen, tobacco mellowing is controlled oxygen concentration in earlier stage below 2%, guarantees the disinsection mold-proof effect, and the later stage is suitably heightened about the interior oxygen concentration to 6% of tobacco leaf stack, in desinsection, creates a kind of environment favourable to tobacco mellowing.
Chinese patent application number: 200810238964.4 have disclosed a kind of disinsection mold-proof method of no effect on tobacco mellowing, be divided into for two steps: the first step adopts oxygen-absorbing material or with nitrogen, carbon dioxide or inert gas the oxygen concentration percent by volume that tobacco leaf stores in the sealing bag is reduced to 0.01-4%, seals 10-400 days; Second step supplemental oxygen or air in the tobacco leaf sealing bag make the oxygen concentration percent by volume in the bag rise to 4-40%, and the storage time is 10-700 days.The method does not disclose the concrete operation method that falls oxygen and supplemental oxygen, and people can't be operated according to the method for document introduction.In addition, when the supplemental oxygen in later stage, if from rise to suddenly natural environment or higher aerobic environment below 2%, can cause that quality of tobacco is violent to become bad, such as the fierce oxidation color burn of tobacco leaf, reduce the tobacco leaf sucking quality.
Summary of the invention
Technical problem to be solved by this invention is for the existing above-mentioned deficiency of prior art, and a kind of tobacco leaf storage alcoholization control oxygen disinsection mold-proof method is provided, the capability and performance that its disinsection mold-proof is effective, do not affect tobacco leaf in the alcoholization process.
In order to address the above problem, the technical solution adopted in the present invention is that this tobacco leaf storage alcoholization control oxygen disinsection mold-proof method may further comprise the steps: (1) oxygen concentration is down to less than 2%: tobacco leaf is positioned over seal cavity, use nitrogen making machine that oxygen concentration in the seal cavity is down to less than 2%, kept this concentration 20-40 days; (2) substep improves oxygen concentration to 15%: use oxygenating equipment to be filled with air oxygen concentration in the seal cavity is increased to 15% step by step.
Preferably, described substep raising oxygen concentration to 15% required time is 70-1155 days.
Preferably, described substep improve oxygen concentration first with oxygen concentration from rising to 2-6% less than 2%, and kept this concentration 10-15 days.
Preferably, described substep improves oxygen concentration oxygen concentration is risen to 6-10% from 2-6%, and keeps this concentration 1-36 month.
Preferably, described substep improves oxygen concentration oxygen concentration is risen to 10-15% from 6-10%, and keeps this concentration 1-2 month.
Storage condition when the present invention adopts substep to rise oxygen control tobacco mellowing.This tobacco leaf storage alcoholization initial stage is adopted the air in the nitrogen making machine Rapid replacement seal cavity, reaches the purpose of falling oxygen, keeps progressively oxygen concentration in the seal cavity being regulated and control with oxygenating equipment behind low oxygen concentration a period of time killing tobacco pests and the mould again.
Chinese patent CN201541699U has introduced oxygenating oxygen increasing equipment behind a kind of sealed oxygen-reducing pest killing of tobacco, be provided with outlet pipe and air inlet pipeline at the sealed cigarette buttress, be provided with the solenoid electric valve of giving vent to anger on the outlet pipe, be provided with the air inlet solenoid electric valve on the air inlet pipeline, oxygen detection instrument in the sealed cigarette buttress is electrically connected with the input of transducer controller, the output of transducer controller and the 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 air cleaning drying machine entrance point, and the air cleaning drying machine port of export is connected with air inlet pipeline.The present invention utilizes this equipment as oxygenating equipment, oxygen content in the regulation and control tobacco mellowing stage seal cavity.
After oxygen fell in step (1), tobacco-plant pest-insect and mould were killed fully in the seal cavity, and step (2) progressively improves oxygen content in the seal cavity.Better 6% left and right sides tobacco mellowing aesthetic quality because of oxygen concentration, the middle 2-6% of step (2) and 6-10% duration in stage are the longest, and the concrete time decides according to the tobacco mellowing situation, make 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
