Description
Technical Field
The invention relates to the technical field of cigar processing, in particular to a processing technology of tobacco leaves for a cigar coat and a cigar sleeve.
Background
Cigars are tobacco products made from dried and fermented tobacco which are smoked on one end and then smoked hoots on the other end to produce smoke. The main producing countries of cigar tobacco are: brazil, karilong, cuba, dominican republic, honduras, indonesia, mexico, nicaragua, and the united states as well as china, southeast asia. Unlike cigarettes, cigars have very little smoke flavor, usually some fermented tobacco and other flavors. The darker the color of the eggplant leaves, the sweeter and stronger the taste, and the higher the oil and sugar content of the eggplant leaves. Because cigar smoking is somewhat different from cigarette smoking, a typical cigar smoker does not inhale the cigar smoke into the lungs, but instead lets the smoke flow in the mouth, so cigar smokers suffer from lower rates of emphysema and lung cancer than cigarette smokers, but higher rates than non-smokers.
Cigars are a kind of rolled whole tobacco leaves, and the tobacco leaves for making cigars can be divided into a coat, a sleeve and a core according to the application in the product, and are also commonly called as outer wrapper, inner wrapper and core leaf in China. The cigar coat is an essence part of the cigar, has the effects of protecting and beautifying the cigar and improving the taste of the cigar, and plays a decisive role in the quality of the cigar. The quality requirements of high-quality eggplant-coated and eggplant-covered tobacco leaves are high, the physical properties of the incoming material cigar tobacco leaves cannot meet the processing requirements due to low moisture, and meanwhile, the incoming material can carry tobacco beetles and other imagoes and insect eggs of organisms which are generated in the tobacco planting and production links and attached to the tobacco leaves and feed on the tobacco leaves, and cannot be directly used for production. At present, no mature technical system, matched process flow and reasonable process parameters exist in the field of cigar tobacco processing.
A method for manufacturing a dark cigar wrapper is provided in a published Chinese patent with the application number of CN201810270386.6, A, selecting tobacco leaves for manufacturing the dark cigar wrapper; B. uniformly spraying purified water on the tobacco leaves to enable the water content of the tobacco leaves to reach 25% -28%, and then balancing the moisture of the tobacco leaves for 24 hours; C. neatly stacking tobacco leaves in a wooden barrel, and inserting a thermometer; D. putting the wooden barrel filled with the tobacco leaves into a fermentation chamber for fermentation, wherein the temperature of the fermentation chamber is kept at 34-36 ℃, and the humidity of the fermentation chamber is kept at 73% -77%; E. when the temperature of the thermometer reaches 45 ℃, turning the tobacco leaves in the wooden barrel; F. testing the moisture of the tobacco leaves in the wooden barrel every day to keep the moisture of the tobacco leaves at 25% -28%, and continuing to ferment; G. and E, continuously repeating the step E and the step F for fermentation, and obtaining the dark cigar coat after the fermentation is finished. In the application, the fermentation speed is low, the prepared tobacco leaves have poor fragrance after being made into cigars, miscellaneous gas can be mixed in the smoke, and the prepared cigars are not uniformly combusted when being made into cigars.
Disclosure of Invention
In view of the above, the invention provides a process for treating tobacco leaves used for eggplant coats, the tobacco leaves treated by the process have uniform moisture content, and impurities such as scraps or worms are not mixed in the tobacco leaves, so that the tobacco leaves are uniformly combusted when being made into cigars and no miscellaneous gas is generated, and in addition, the treatment in the fermentation process can improve the aroma, the smoking taste and the like of the tobacco leaves.
