Description
Technical field
The present invention relates to technical field of cigarettes, more particularly, to a kind of device and method of hot trapping preparation smoke fragrance.
Background technique
Traditional cigarette generates flue gas by lighting pipe tobacco and meets consumer demand, and when cigarette burning is waved by substance
Hair, pyrolysis and high―temperature nuclei, make have up to more than 7300 compounds in flue gas, wherein by (nearly 900 DEG C of maximum temperature) production of burning
Raw substance has 2740 kinds, these material parts are related with cigarette characteristic scent, but have moieties be harmful to the human body (such as CO,
Benzo [α] pyrene, condensed-nuclei aromatics etc.).
Due to smoke with environment, anti-smoking campaign continue surging and smoker for health demand, low tar,
Less harmful cigarette is more paid attention to, while also flourishing without the new tobacco products of burning.By using electronic cigarette or
Heating does not burn cigarette come to replace traditional cigarette be current Field of Tobacco developing direction.In electronic cigarette and heat the cigarette that do not burn
In, nicotine and most tobacco flavor ingredients can be transferred in flue gas at a lower temperature (usually less than 500 DEG C), because
This will not generate the harmful substance and side-stream smoke that cigarette is generated by high-temp combustion, and cigarette can be greatly reduced to human health
Harm and the pollution to environment.
Electronic cigarette or the heating cigarette etc. that do not burn have smog but incombustible new tobacco products principle is: by heating,
By present in the mist formations such as glycerol, propylene glycol substance, alkaloid, tobacco or additional aroma substance, other flavoring ingredients together
It evaporates to form aerosol, be enjoyed for smoker.Although these products technically have been achieved for rapid progress, mesh
Preceding these products in the market generally have larger gap on taste and aromatic style with traditional cigarette.Its reason is to lack tradition
Cigarette burning and high-temperature retorting pyrolytic process, also just have lost based on fragrance distinctive in flue gas caused by these processes at
Point, it is difficult that smoker is made to obtain the distinctive pleasure of the senses of traditional cigarette, and add traditional tobacco extract and existing flavors and fragrances
Method can not make up this defect.
For this purpose, people are handled tobacco in the way of high temperature pyrolysis, imitate conventional cigarette in combustion into
The complex reactions process such as capable thermal cracking, Mei Lade obtains tobacco response product and is used for new tobacco products, can be in certain journey
It makes up electronic cigarette on degree or the do not burn new tobacco productses such as cigarette insufficient fragrance, smoke feature of heating lacks or unobvious etc. lack
It falls into.
But the research of the related tobacco pyrolysis of the prior art is concentrated mainly on pyrolysis temperature to Product safety and organoleptic attribute
Influence.Existing heating method will lead to tobacco-containing material uneven heating, wherein the portion temperature with heater contacts is higher, far
It is lower from the portion temperature of heater, the phenomenon that Yi Fasheng is charred, influence the mouthfeel of destructive distillation fraction.Meanwhile the prior art is often
Using being pyrolyzed in closed container, offal is easy to blackening in anaerobic high-temperature heating process, is also easy to produce the tobacco tar of black, obtains
Product smoke is overweight.Meanwhile there is arresting efficiency difference in the prior art.
Summary of the invention
