Description
Technical Field
The invention relates to the technical field of cigarettes, in particular to a device and a method for preparing a smoke flavor.
Background
The traditional cigarettes meet the demands of consumers by igniting tobacco shreds to generate smoke, and the smoke contains more than 7300 compounds by means of substance volatilization, pyrolysis and high-temperature synthesis when the cigarettes are burnt, wherein 2740 substances generated by combustion (the highest temperature is approximately 900 ℃) are included, part of the substances are related to the characteristic fragrance of the cigarettes, and part of the substances are harmful to human bodies (such as CO, benzo [ alpha ] pyrene, polycyclic aromatic hydrocarbon and the like).
Because of the continuous rising of smoking and environment and back smoking movements and the physical health demands of smokers, low-tar and low-harm cigarettes are more emphasized, and meanwhile, new tobacco products which are not combusted are also vigorously developed. Replacing traditional cigarettes with electronic cigarettes or heated non-combustible cigarettes is currently a direction of development in the tobacco field. In the electronic cigarette and the heating non-combustible cigarette, nicotine and most tobacco flavor components can be transferred into smoke at a lower temperature (generally lower than 500 ℃), so that harmful substances and side-stream smoke generated by high-temperature combustion of the cigarette cannot be generated, and the harm of the cigarette to human health and the pollution to the environment can be greatly reduced.
The novel tobacco product principles of smoke such as electronic cigarettes or heating non-burning cigarettes and the like and not burning are as follows: by heating, the fog substances such as glycerin, propylene glycol, alkaloids, aroma substances existing in tobacco or added with tobacco and other flavoring components are volatilized together to form aerosol for the smoker to enjoy. While these products have made great advances in technology, these products currently on the market are widely separated from traditional cigarettes in taste and aroma styles. The reason is that the special flavor components in the smoke generated by the processes are lost due to the lack of the traditional cigarette burning and high-temperature carbonization pyrolysis processes, so that the smoker can hardly obtain special sensory enjoyment of the traditional cigarette, and the defect cannot be overcome by the method of adding the traditional tobacco extract and the existing essence and spice.
Therefore, people treat the tobacco by utilizing a high-temperature pyrolysis mode, imitate the complex reaction processes of thermal cracking, maillard and the like in the combustion process of the traditional cigarette, obtain a tobacco reaction product and use the tobacco reaction product in novel tobacco products, and can compensate the defects of insufficient flavor, lack of smoke flavor characteristics or unobvious smoke flavor characteristics and the like of the novel tobacco products such as electronic cigarettes or heated incombustible cigarettes to a certain extent.
However, prior art studies on tobacco pyrolysis have focused mainly on the impact of pyrolysis temperature on product safety and organoleptic properties. The existing heating mode can lead to uneven heating of tobacco materials, wherein the temperature of the part contacted with the heater is higher, the temperature of the part far away from the heater is lower, the phenomenon of scorching is easy to occur, and the mouthfeel of the dry distillation fraction is affected. Meanwhile, the prior art usually adopts pyrolysis in a closed container, the tobacco powder is easy to turn black in the anaerobic high-temperature heating process, black tobacco tar is easy to generate, and the smoke taste of the obtained product is too heavy. Meanwhile, the prior art has the problem of poor trapping efficiency.
