Reduce the beating and double roasting method of phenol release amount
Technical field
The invention belongs to raw material of cigarette manufacture field, be specifically related to a kind of beating and double roasting method reducing phenol release amount.
Background technology
Along with society is to the concern of smoking and health problem, in cigarette, harmful components are also more subject to people and pay close attention to, and wherein phenol is that a kind of Volatile phenolics in flue gas has intense stimulus effect to skin and respiratory mucosa.
Within 2009, State Tobacco Monopoly Bureau is using comprising cigarette smoke 7 kinds of harmful components of phenol as the important indicator characterizing cigarette mainstream flue gas biohazardous, show that cigarette Evaluation of Harmfulness index weighs the security of cigarette by measurements and calculations.
How to reduce the phenol release amount in cigarette mainstream flue gas, have much research in recent years but mostly this type of research is that the filter tip by adding additive, reconstituted tobacoo or prepare special material in cigarette realizes.As Chinese patent ZL201010278342.1 patent proposes a kind of chitosan polycation composite material reducing phenol substances in cigarette smoke gas, make an addition in composite cigarette filter stick, utilize the phenol harmful substance in the moisture selective reduction cigarette smoke in composite.The patent of invention of Chinese patent ZL200710192692.4 proposes a kind of papery cigarette filter tip of high phenol clearance and fluorine-containing surfactant is applied at papery cigarette filter tip, alternatively reduces phenol content in cigarette smoke.More than study and achieve better effects in the effect reducing phenol release amount in cigarette smoke, have also been obtained and apply comparatively widely, but this method also comes with some shortcomings, the coordination of such as additional functional additive and cigarette flavor, large etc. to the loss of cigarette flavor, technical difficulty.And existing beating and double roasting technology mainly focuses on improving tobacco leaf physical arrangement, chemical composition uniformity etc. after beating and double roasting, be conceived to process with Recipe leaf beating with aesthetic quality or similar the homogenizing of routine chemical components.Tobacco threshing and redrying processing technology is utilized not given and attention to reduce phenol release amount in cigarette smoke at present, also relevant patent and bibliographical information is had no, therefore, a kind of beating and double roasting method reducing phenol release amount in cigarette smoke, under the prerequisite guaranteeing raw tobacco material product style, phenol release amount in reduction cigarette smoke is moved forward to the beating and double roasting stage by the method, not only effective, simple and easy to do, and the coordination problems such as outer doping and cigarette smoke can be avoided, there is important value for raising safety cigarette.
Summary of the invention
The object of this invention is to provide a kind of beating and double roasting method reducing phenol release amount, the method can effectively reduce the phenol release amount after beating and double roasting in cigarette smoke, controls phenol release amount from the raw material of cigarette.
In order to reach above-mentioned technique effect, the present invention takes following technical scheme:
A kind of beating and double roasting method reducing phenol release amount, mainly comprise wind dispensing operation and smoked sheet multiple roasting operation, before wind dispensing operation, increase hot blast leaves moisting operation, namely hot blast leaves moisting operation is after a profit, two profit operations, and the temperature of hot blast leaves moisting is 80 ~ 120 DEG C.
In order to further reduce the phenol release amount in tobacco leaf, the fight each other parameter of leaf wind operation break-down of the present invention has carried out following optimization, the technological parameter of described wind dispensing operation is as follows: a dozen rotating speeds 620r/min, two spin fast 550r/min, three spin fast 585r/min, four spin fast 859r/min, and five spin fast 615r/min.
In order to further reduce the phenol release amount in tobacco leaf, the present invention has carried out following optimization to the parameter of smoked sheet multiple roasting operation, the technological parameter of described smoked sheet multiple roasting operation is as follows: guipure speed 32Hz, dry district's temperature 55 DEG C, dry two district's temperature 90 DEG C, dry three district's temperature 68 DEG C, dry four district's temperature 55 DEG C.
The present invention compared with prior art, has following beneficial effect:
(1) this method increases hot blast leaves moisting operation before wind dispensing operation, under the prerequisite keeping cigarette style, can effectively reduce phenol release amount in flue gas.
(2) this method further optimizes the technological parameter of wind dispensing operation and redried leaf tobacco operation, can further reduce phenol release amount in flue gas.
(3) the raw tobacco material aesthetic quality fluctuation obtained after parameter adjustment can not be too large, otherwise can affect raw material usability, thus affect consumer to the acceptance of cigarette product and the degree of recognition.So this method should be suitable to the adjustment of technological parameter, also need ensure raw tobacco material aesthetic quality and reduce phenol release amount in flue gas.

Detailed description of the invention
Below in conjunction with embodiments of the invention, the invention will be further elaborated, and following examples are to further illustrate content of the present invention, instead of limitation of the present invention.
Embodiment 1:
The tobacco sample that obtains will be produced as blank sample by existing beating and double roasting process parameter; Wherein increase hot blast leaves moisting treatment process newly for somewhere B3F tobacco leaf in 2011, producing the tobacco sample obtained is optimization sample.Tobacco sample is with after condition loosening and gaining moisture, chopping, the naturally system of drying in the air, and rolling cigarette sample, the phenol in smoke content detection of sample is in table 1.
Table 1:B3F optimizes sample and blank sample phenol release amount testing result
As can be seen from Table 1, under newly-increased treatment process condition, B3F produces phenol release amount in the tobacco sample flue gas obtained and reduces 16.26% than blank sample, has and significantly reduces phenol release amount effect.
Embodiment 2:
The tobacco sample that obtains will be produced as blank sample by existing beating and double roasting process parameter; Somewhere B3F tobacco leaf in 2011, according to different technical parameters and Optimizing Process Parameters combination, all the other procedure technology parameter constants, produce the tobacco sample 1 ~ 3 and optimization sample that obtain; Each group of tobacco sample is with after condition loosening and gaining moisture, chopping, the naturally system of drying in the air, and rolling cigarette sample, the phenol in smoke content detection of sample is in table 2.
Table 2: wind dispensing process optimization sample and blank sample phenol release amount testing result
As can be seen from Table 2, in wind dispensing operation, upper tobacco leaf B3F produces phenol content in the tobacco sample flue gas obtained under combination of process parameters after optimization and reduces 11.03% than blank sample, all has and significantly reduces phenol content effect.
Embodiment 3:
The tobacco sample that obtains will be produced as somewhere B3F tobacco leaf in 2011 as blank sample by existing beating and double roasting process parameter; According to different technical parameters and Optimizing Process Parameters combination, all the other procedure technology parameter constants, produce the tobacco sample 1 ~ 3 and optimization sample that obtain; Each group of tobacco sample with after condition loosening and gaining moisture, chopping, the naturally system of drying in the air, rolling cigarette sample.The phenol in smoke content detection of sample is in table 3.
Table 3 redrying process optimization sample and blank sample phenol release amount testing result
