A kind of method of mechanical damping leaves moisting of Storage tobacco being carried out in dried, dead season
Technical field
The present invention relates to a kind of method of mechanical damping leaves moisting of Storage tobacco being carried out in dried, dead season.
Background technology
Tobacco leaf after gathering then will could use through storing the alcoholization cycle more than 1 year.Because the defective of new cigarette various degrees on quality, show as that fragrance fails to appear, excitant is large, blue foreign smell is heavier, the assorted gas of region is outstanding, flue gas is coarse etc., must tabacco fragrance be manifested by natural alcoholization or fermentation, eliminate blue foreign smell, abirritate, improve pleasant impression and tobacco leaf flammability, to satisfy the cigarette industry requirement.
The purpose of tobacco natural alcoholization is in order to overcome the bad quality of new cigarette, to improve and improve inherent quality and the presentation quality of tobacco leaf, making it to be suitable for the needs of cigarette product quality.Natural alcoholization also claims " ageing ", is a kind of gentleness and fermentation process is slowly deposited in the tobacco leaf after redrying in the warehouse usually, the alcoholization slowly with the variation of temperature in four seasons, through the time of 12~30 months, make its quality be improved significantly.
Tobacco natural alcoholization not only aroma quality obviously is better than the artificial fermentation, and the stability that keeps cigarette quality is played an important role.The cigarette product trade mark, particularly famous-brand and high-quality cigarette quality style must stable for extended periods of time once typing.If raw tobacco material is not enough stocked, can not satisfy the needs of cigarette composition on quantity, kind, area, Quality Grade, certainly will to change at any time tobacco leaf formulation, cigarette product will be subject to very big impact.Implement tobacco natural alcoholization, the tobacco leaf stockage is more abundant, even run into the time of tobacco leaf supply shortage, what arranged one or two years stocks tobacco leaf for the basis, by adjusting gradually tobacco leaf formulation, can keep the stable of cigarette quality.
The alcoholization quality of tobacco leaf mainly comprises tobacco leaf presentation quality, physical characteristic, chemical composition and aesthetic quality's four major parts, and they are from different aspect reflection quality of tobacco features.Presentation quality is the important evidence of tobacco leaf grading, and chemical composition and aesthetic quality are mainly reflected the inherent quality of tobacco leaf, and the tobacco leaf physical characteristics can reflect quality of tobacco, the anti-processability of tobacco leaf and economic characters.
The factor that affects the tobacco mellowing quality is a lot, and principal element has:
1. the equilibrium moisture content of tobacco leaf (%): it had both reflected the processability of tobacco leaf, had also directly affected process and the alcoholization quality of tobacco natural alcoholization, the tobacco leaf moisture content is too low can affect the natural alcoholization process, but the too high meeting of moisture content deepens tobacco leaf color, impact alcoholization quality, the tobacco leaf moisture content remains on the natural alcoholization that 12%~13% scope is conducive to tobacco leaf most, when envionmental humidity remains on 55%~65%, the tobacco leaf moisture content will also be stabilized between 12%~13%;
2. the air themperature in storage environment: temperature is higher, and it is strong that the biochemistry in tobacco leaf changes Shaoxing opera, and alcoholization speed is faster; And the storage temperature is lower, and it is slower that the biochemistry in tobacco leaf changes, and alcoholization speed is slower, and the optimum temperature of tobacco mellowing is 20 ℃-30 ℃, and actual warehouse temperature should be controlled between 15 ℃-30 ℃ at least.
3. oxygen: the essence of tobacco natural alcoholization process is the inherent chemical composition degraded of tobacco leaf, transforms and the process of synthesizing, and could fully complete when these process majorities need to have oxygen to exist.The early stage of natural alcoholization and mid-term need to be strengthened the alcoholization that mechanical damping is conducive to tobacco leaf.
Current, tobacco business Storage tobacco great majority are wide geographic areas of storage maintenance and alcoholization, particularly North of Huai River under natural conditions, enter autumn end, winter and season in the early spring, dry cold.Take the Beijing area as example: the environmental simulation of environment institute of Beijing Normal University has been carried out monitoring confirmation (winter in Beijing different landscape underlying surface humiture degree variation characteristic----Acta Ecologica Sinica in year February in December, 2007 to 2008 to temperature, the humidity diurnal variation of 5 observation stations of Beijing with Liu Jiaomei, Yang Zhifeng that National Key Laboratory is controlled in pollution, the 29th the 6th phase of volume of June in 2009), in December~January, the mean temperature of Beijing is for reaching-6~8 ℃, and medial humidity is 25~45%; In February, the mean temperature of Beijing is-4~10 ℃, and medial humidity is 10~25%.
In above-mentioned area, after entering autumn and winter, the atmospheric environment humiture lower than the ambient temperature and humidity of ambient temperature and humidity, inside, warehouse in the storehouse again lower than the humiture of tobacco leaf stack inside in the storehouse, the gradient difference of the inside and outside humiture of the inner tobacco leaf stack in this warehouse will cause the hot transport phenomenon (moist heat transfer) that the gas in tobacco leaf stack is occured to the low temperature position by high temperature position.Be accompanied by the transmission of above-mentioned heat, moisture content in leaves just by high temperature position to the low-temp. portion bit transition, finally can make moisture content in leaves constantly shift and volatilize to be diffused in environment to the stacking skin and go, the moisture in tobacco leaf stack is through tending to descend 2~5 percentage points a winter.The ground winter temperatures such as domestic Harbin, Zhangjiakou, the Inner Mongol, Xinjiang are lower, and the moisture content of Storage tobacco may only maintain 8~10%, well below the scope that is conducive to most tobacco natural alcoholization 12%~13%.Like this, the northern area of China stock's tobacco leaf is difficult to complete good natural alcoholization basically, can not provide the raw tobacco material of producing the high-grade cigarette goods, and economic loss is huge.
Moreover 8~10% low-water-content can cause that again the chip rate of tobacco leaf improves, and increases the quality of tobacco loss in the tobacco leaf handling process, and the anti-processability of tobacco leaf and economic characters also can variation.
And on the other hand, the southern area spring of China, summer, air humidity was generally larger, and Storage tobacco very easily absorbs airborne moisture and goes mouldy, particularly when temperature is more than 20 ℃, and the larger a little possibility that just may occur going mouldy of tobacco leaf humidity.
In order to address the above problem, in the urgent need to the pattern of simply implementing conventional tobacco conservation measure take a whole tobacco leaf warehouse as unit before changing, a kind ofly carry out airtight take each tobacco leaf stack as the unit and then complete with mechanical damping, manually moisten the new tobacco leaf warehousing maintenance measure of tobacco leaf in the urgent need to adopting.
In order to solve the series of technical in the tobacco leaf storage maintenance, the inventor has applied for utility model patent-" sealed tent for stacked tobacco leaves " (patent No. ZL2009 2 0086679.5) in 2009, although this patent provides a kind of tobacco leaf stack sealing method, do not further describe the method to the damping of tobacco leaf machinery; The inventor has applied for patent of invention in 2009---" can regulate and control the multifunctional tobacco leaf stack sealing storage method of storage environment " (patent No. ZL2009 1 0062727.1), although this patent provides for the storage maintenance technology system that stores tobacco leaf, but the tent inner surface dewfall that is prone to when relying on this patented technology still can not solve under tobacco leaf stack artificial mechanism humidification from cryogenic conditions to sealing and the problem of freezing, moist heat transfer still can occur the internal moisture of tobacco leaf stack causes moisture content in leaves to run off; The inventor has applied for again patent of invention in 2011---" a kind of mechanical regulation, manual nitrogen charging store the method for tobacco leaf "; this patented technology mainly has been to provide the technical method of a cover environmental protection chemoprevention worm, mildew-resistant, but for tobacco leaf damping leaves moisting problem under the low temperature drying condition relate to less, the control index system that a cover is suitable under the low temperature drying condition, tobacco leaf stack being carried out mechanical damping leaves moisting operating technology do not proposed.
In the production real work of tobacco storage industry, once occurring in the winter time tobacco leaf warehouse being carried out the artificial heating of machinery heats, then in tobacco leaf warehouse more artificial humidification keep humidity in tobacco leaf stack, but the formed high humidity environment of this way is easily destroyed by the stream of people, the logistics that tobacco leaf warehouse constantly passes in and out, and the warehouse energy consumption is quite serious.
in sum, in present production reality and existing patented technology, there is no one damp and hot and northern Arid-cold regin for south, can satisfy tobacco leaf stack sealing and mechanical damping leaves moisting and maintenance upgrading system construction and operation method comprehensively, be mainly manifested in the environment control measure that do not suppress tobacco leaf stack generation moisture moist heat transfer in existing storage technique, do not build a kind of tobacco leaf stack damping that is conducive to, the encapsulating method of moisturizing, there is no a kind of measure that tobacco leaf stack humidity is kept that is conducive to, neither one is suitable for the temperature of Arid-cold regin Storage tobacco safe overwintering, humidity is controlled the index combination, existing tobacco warehouse humiture control measure energy consumption is high, waste is serious.
