Description
Technical field
The invention belongs to the tobacco storage technical field, relate to a kind of tobacco leaf storage sealing compound.
Background technology
Seal ultralow oxygen (Ultra low-oxygen ULO) storage practice and come from Britain, the principle of this storage method is meant by the oxygen under the storage environment is controlled at below 2%, thereby the respiratory activity of stored article is suppressed, substantially be in resting state, breathe the nutriment consumed and reduce, so the nutrient component of article and quality can be kept preferably.The environment of ultralow oxygen also can suppress and kill microorganism and the plant pest in the storage environment simultaneously.
Seal ultralow oxygen storage practice and be widely used in fields such as the article that need store in a warehouse such as fruit, grain, tobacco.In the tobacco field, because need being deposited in by certain requirement, tobacco leaf carries out natural alcoholization in the warehouse, by control temperature, humidity, under hypoxia, refine, the alcoholization time is generally 1-3, at present main what use is that iron is that oxygen falls in oxygen absorbent, but this oxygen absorbent seals in the ultralow oxygen storage at tobacco leaf, has following problem:
1. it is too fast to fall oxygen.Present tobacco leaf air conditioning agent all is to adopt efficiently iron system to fall the oxygen agent to fall oxygen, and this principle of falling the oxygen agent is to utilize reduced iron powder oxidized and consume oxygen, thereby reaches the purpose of falling oxygen.This oxygen mode of falling belongs to an exothermic reaction on thermodynamics, owing to fall oxygen excessive velocities (generally oxygen concentration just drops to below 2% within 15 days), liberated heat makes that the interior local temperature of cigarette buttress is too high, can cause the temperature at tobacco leaf center can not distributed when serious, phenomenons such as tobacco leaf goes rancid, heartburn, knot plate occur, make tobacco leaf forfeiture use value.
2. it is slow to fall wet speed.Tobacco leaf storage has an optimal spatial relative moisture scope usually, and general requirement of cigar mill remains on the relative moisture in tobacco leaf storage space in the scope of 50%-65% at present, and existing air conditioning agent can not be controlled the relative moisture of environment.If tobacco leaf is in the environment of high humidity high temperature (such as southern summer) for a long time, owing to have mould in the tobacco leaf, and mould very easily growth under the condition of high humidity high temperature, thereby cause tobacco mildew, forfeiture use value.And that wet speed falls in the medicament that uses at present is slow, therefore probably causes tobacco mildew.Because existing tobacco leaf air conditioning agent all is will have the material that falls oxygen, falls wet function simultaneously to mix and make, this makes air conditioning agent fall wet slow-footed shortcoming and becomes more obvious.
3. tobacco leaf the dewfall phenomenon occurs in the sealing storage.If the phenomenon of dewfall appears in tobacco leaf, then illustrate in the local local humidity of dewfall too high, thereby improved the probability that tobacco leaf goes mouldy, the musty that tobacco mildew produced can influence whole cigarette buttress, and the quality of whole cigarette buttress is descended.
4. the CO of existing tobacco leaf air conditioning agent to producing in the tobacco mellowing process
2Absorb less, CO
2Excessive concentration the alcoholization of tobacco leaf is suppressed (with CO
2The rising of concentration, the alcoholization reaction balance is destroyed, and alcoholization is suppressed), thereby the continuation that is unfavorable for tobacco leaf is refined.
The packing of existing controlled atmosphere sealing compound mainly contains following two kinds of forms: a kind of is to adopt the brown paper packaging bag, and another kind is to adopt plastic film to pack, and irregularly has several holes on the plastic film.For the air conditioning agent of packing with brown paper, it falls the oxygen excessive velocities, and the dewfall phenomenon easily takes place.And for the controlled atmosphere sealing compound of the plastic film packaging with random punching number, it falls oxygen speed may be too fast, also may be slow excessively: it falls the oxygen excessive velocities more for a long time when the punching number, easily dewfall; And the punching number more after a little while, and it is slow excessively to fall oxygen speed, can not in 30 days oxygen concentration be reduced to below 2%, and these all might damage the quality of tobacco leaf.
