Description
Technical Field
The utility model belongs to the technical field of the tobacco modulation, concretely relates to controllable flue-cured tobacco room that dries in air of simple and practical, energy consumption is low, efficient high efficiency.
Background
Air-cured tobacco is one of the common types of tobacco and has been used for a long time in history, and is generally divided into light-colored air-cured tobacco (burley and Maryland) and dark-colored air-cured tobacco, which are air-cured in shady and cool ventilating places. In China, except that burley tobaccos are used as a tobacco type independently, all other air-cured tobaccos, including cigar wrapper tobaccos, Maryland tobaccos and other traditional air-cured tobaccos, belong to the air-cured tobacco types.
The tobacco leaves at the middle and lower parts of the cigar wrapper tobacco are thin and light after being aired, the leaf vein is thin, the texture is fine, the elasticity is strong, the color is uniform and consistent dark brown or brown, the combustibility is good, and the cigar wrapper tobacco can be used as a raw material of cigar wrapper tobacco. Maryland tobacco is light air-cured tobacco, has the characteristics of strong resistance, wide adaptability, larger and thinner leaves and the like, has good flame-retardant property and aromatic taste, so that when the Maryland tobacco is mixed with other types of tobacco leaves, the flame-retardant property of the cigarette can be improved, and the fragrance and the taste are not disturbed. The traditional tobacco curing method is to hang the whole tobacco in a cool and ventilated place, and pile, process and ferment the tobacco after the tobacco leaves are dried. The prepared tobacco leaves are black brown, have enough oil content, strong elasticity, full taste and good combustion performance.
The flue-cured tobacco is also called fire tube flue-cured tobacco, and is mainly characterized by that the plant is tall and large, the leaf distribution is relatively sparse and uniform, and the flue-cured tobacco is mature from bottom to top, and can be harvested in several times. The original preparation method is also airing, baking is used later and is used till now, and the baking process is continuously optimized along with the technical progress. The cured tobacco prepared in the curing barn is golden yellow after curing, and has high sugar content, low protein content and moderate nicotine content. Flue-cured tobacco is the tobacco type with the largest cultivation area in China and the world, and is the main raw material of the cigarette industry.
However, with the rise of novel tobacco, the diversification of the smoking demand of the tobacco of consumers puts higher requirements on the diversification of the cigarette raw materials, the research and development of the heating non-combustion cigarette technology is in a key development stage, and the baking process technology of the raw materials is not mature. The method provides raw materials with diversified styles for cigarettes, and is particularly important for exploring the modulation results of different modulation modes for the same tobacco type. The flue-cured tobacco is one of the types of tobacco with the largest planting area in China, and the flue-cured tobacco is aired to obtain different types of tobacco raw materials, so that the flue-cured tobacco is necessary to provide rich tobacco raw material materials for cigarette manufacturing. At present, the research report of the modulation of the flue-cured tobacco by the air-curing method is reported in China, and the document 'the influence of the flue-cured tobacco and burley tobacco interchange modulation method on the neutral aroma substance content and the sensory quality of the tobacco leaves' (Chinese tobacco science report, 2015,21(04): 34-39.) reports that although the air-curing condition is not beneficial to the accumulation of the characteristic aroma substances of the flue-cured tobacco, the total amount of brown reaction products of the flue-cured tobacco and the content of solanone can be obviously improved; the style, aroma quality and sweet feeling of the flue-cured tobacco are reduced under the airing condition, and the irritation is increased.
Among the current flue-cured tobacco modulation technique, toast is the main modulation mode, and it is rare to carry out the system of drying in the air with the flue-cured tobacco, and the technical utility model to the system of drying in the air of flue-cured tobacco is rare especially. At present, most of the air-drying rooms for modulation are open air-drying rooms, standard air-drying rooms built in partial areas of China and partially adopted circulating fan air-drying rooms, the temperature and humidity regulation and control range is limited due to poor sealing performance, the requirement of air-drying accurate data cannot be met, the air-drying effect is unsatisfactory, the problem of easily modulating vinasse smoke is caused, fuel consumption is high, the air-drying cost is greatly increased, and the large-area popularization and energy consumption are not facilitated.
