Description
Technical Field
The invention relates to the technical field of tobacco processing, in particular to a method for accelerating tobacco mellowing.
Background
After the tobacco leaves are redried, the internal quality is obviously improved compared with that of the primary-cured tobacco leaves, but the redried tobacco leaves are naturally alcoholized for a long time under certain conditions to ensure that the whole chemical components of the tobacco leaves tend to be coordinated, various chemical and biological changes which are beneficial to the fragrance and taste of the tobacco leaves are slowly and fully carried out, and the optimal use effect is achieved.
The conventional tobacco mellowing methods are classified into artificial fermentation methods and natural mellowing methods. The tobacco leaf artificial fermentation method is characterized in that tobacco leaves are placed in a special fermentation chamber and alcoholized for a short time under the conditions of high temperature and humidity (the temperature is 40-55 ℃ and the relative humidity is 50-80%), and the alcoholization period is generally 12-22 days. The natural alcoholization method is to naturally store the tobacco leaves in a warehouse (alcoholization warehouse) for about 2-3 years and slowly alcoholize the tobacco leaves.
The quality of the tobacco leaves alcoholized by the artificial fermentation method is far inferior to that of the tobacco leaves alcoholized by the natural alcoholization method, so that the traditional artificial fermentation process and equipment of the tobacco leaves are eliminated at present, and the tobacco enterprises comprehensively pursue the natural alcoholization process of the tobacco leaves. The natural alcoholization period of the tobacco is long, so that the tobacco leaf stock is large, the occupied capital and the warehouse area are large, the maintenance cost is high, huge economic burden is caused to cigarette enterprises, and the economic benefit of the enterprises is limited to be further improved; on the other hand, because the supply and quality of the tobacco raw materials are instable in years, the phenomenon of shortage of alcoholized tobacco raw materials often occurs in the cigarette production, and the production efficiency of cigarettes is reduced.
In order to solve the above problems, patent application No. CN201110213068.4 discloses an alcoholization period adjustable tobacco alcoholization chamber and a method for regulating and accelerating tobacco alcoholization, wherein the alcoholization chamber is equipped with a temperature and humidity regulation system and an air circulation system, and temperature and humidity parameters can satisfy the dual-function requirements of slow alcoholization and fast alcoholization of tobacco. The controllable range of the alcoholization warehouse temperature is 25-40 ℃, and the controllable range of the relative humidity is 50% -75%; the controllable range of the tobacco mellowing period is 1-18 months. The tobacco raw materials are sent into a tobacco alcoholization warehouse, and the tobacco alcoholization is quantitatively regulated and accelerated by adjusting the temperature and humidity parameters of the warehouse. When the method in the patent is adopted for tobacco mellowing, a special heat insulation purification warehouse is required to be configured, so that the use cost of equipment is increased; and the tobacco leaves are kept at a higher temperature for a long time during purification, so that the energy consumption is improved, the volatilization of aromatic substances generated in the alcoholization process is accelerated, and the quality of the tobacco leaves is influenced.
