Abstract
The invention belongs to the technical field of cigarette production, in particular to a tobacco harm reduction processing solvent and a method for selectively reducing releasing amount of ammonia in mainstream cigarette smoke by the aid of the tobacco harm reduction processing solvent. The tobacco harm reduction processing solvent is made of water, a potential-of-hydrogen modifier and an additive. Cell wall structures of cigarette cells are destroyed through the tobacco harm reduction processing solvent so as to enable nitrogen substances like part of protein, ammonium salt and amino acid to dissolve out, and ammonia precursor substances formed during burning of tobacco can be reduced, and the releasing amount of harmful ingredients can be reduced. The method for reducing ammonia in the mainstream cigarette smoke mainly includes the steps of solvent leaching, washing, drying and the like. The processing technology is simple and convenient in process, low in energy consumption, widely applicable to tobacco types and good in promotion and application value.
Description
Technical field
The invention belongs to production of cigarettes technical field, be specifically related to the harm reduction that grows tobacco and process solvent and utilize the alternative tobacco harm reduction processing method that reduces ammonia of main stream smoke of cigarette burst size of this solvent.
Background technology
In recent years, along with national governments, health organization and the common people pay attention to day by day to " smoking is with healthy " problem, harmful components in cigarette mainstream flue gas have become one of focus of people's concern, and for this reason, China also proposes to provide for consumer the target of healthy cigarette.
At present change lowering harm and decreasing coking into from reducing tar and reducing harm for the processing direction of pipe tobacco in production of cigarettes process, and proposed to reduce carbon monoxide, hydrogen cyanide, 4-(methyl nitrosamino group)-1-(3-pyridine radicals) target of main harmful components in-1-butanone (NNK), ammonia, benzo [a] pyrene, phenol and seven kinds of main flumes of crotonaldehyde.At present, set up for professional standard and the detection method of main Harmful ingredient content in seven kinds of main flumes, industry inside and each tobacco company are also putting forth effort that relevant production technology is done to further adjustment and improvement.
Ammonia is a kind of natural component in tobacco.Owing to being acid for the tobacco of cigarette, so the ammonia in tobacco is to exist with proton form, exist with the ammonium salts of natural carboxylic acid in tobacco, escape otherwise can volatilize.Although ammonia content is far below in solid pipe tobacco in the main flume after result of combustion of tobacco, because it directly acts on human body, thereby its harmfulness also can not be ignored.Because ammonia not only affects the jealous of cigarette, also can stimulate vision and the respiratory system of human body, long-term suction meeting causes serious harm to human body, and therefore ammonia is also considered to the main harmful components of one in main flume after result of combustion of tobacco.
Along with the intensification to human health damage understanding to ammonia, people start the main precursor component of ammonia in flue gas and form mechanism to conduct a preliminary study.Existing research shows, the main precursor of ammonia is protein, and therefore, reducing associated precursors thing in tobacco is the content of protein, just likely reduces the burst size of ammonia of main stream smoke of cigarette.But, in prior art, there is not yet the harm reduction treatment process of comparatively ripe relevant tobacco.
Summary of the invention
The object of the present invention is to provide the harm reduction that grows tobacco to process solvent and tobacco harm reduction processing method, thereby can reduce the burst size of ammonia after result of combustion of tobacco.
The technical solution used in the present invention is as follows:
One grow tobacco harm reduction process solvent, comprise water, acidity-basicity regulator and additive;
Described acidity-basicity regulator is: one or more a certain proportion of mixtures in acetic acid, sodium acetate, NaOH, potassium hydroxide, saleratus or sodium acid carbonate; The concentration of acidity-basicity regulator is 10
-5～10
-3mol/L;
Described additive is: one or more a certain proportion of mixtures in Tween-20, Tween-60, Tween-80, sldium lauryl sulfate, cetyl benzene sulfonic acid sodium salt.
Solvent is processed in described tobacco harm reduction, and the mass content of additive is 0.5%～1.5%.
Solvent is processed in described tobacco harm reduction, and more excellent proportioning is, water, sodium acetate, Tween-20, and sodium acetate concentration is 10
-3mol/L, the mass content of Tween-20 is 1.0%.
Tobacco harm reduction is processed every material in solvent and after evenly mixing, is tobacco harm reduction processing solvent.
Utilize tobacco harm reduction to process solvent soaking and process tobacco, can destroy to a certain extent the cell wall structure of tobacco cell, make the nitrogen substance component strippings such as partially protein, ammonium salt, amino acid, thereby the precursor substance of the ammonia forming while making result of combustion of tobacco reduces, thereby reduce the burst size of harmful components, thereby the method for treatment of tobacco that utilizes tobacco harm reduction to process solvent reduction ammonia of main stream smoke of cigarette burst size provided by the present invention, mainly comprise solvent leaching, washing and drying and other steps.
Utilize tobacco harm reduction to process the method for solvent reduction ammonia of main stream smoke of cigarette, comprise the following steps:
(1) by fixing tobacco packing, then process solvent with harm reduction and soak;
The mass ratio that solvent and tobacco are processed in described harm reduction is that Rong Ji ︰ tobacco=10 ~ 20 ︰ 1 is processed in harm reduction, preferably harm reduction processing Rong Ji ︰ tobacco=15 ︰ 1;
Described immersion is under 10 ~ 40 DEG C of conditions, soaks 10 ~ 100min; Preferably, under 30 DEG C of conditions, soak 30min;
(2) step (1) being soaked to rear tobacco washes;
Described washing is that tobacco clear water or deionized water that tobacco harm reduction processing solvent soaking is crossed are embathed, clear water/deionized water and tobacco quality ratio, clear water/Qu Li Shui ︰ tobacco=10 ~ 20 ︰ 1, preferably clear water/Qu Li Shui ︰ tobacco=15 ︰ 1, embathes 10 ~ 20min; Embathe can according to actual embathe effect and need to embathe once, twice or repeatedly, water logging is washed object and is to remove residual tobacco harm reduction and processes solvent, avoids affecting for cigarette smoking mass formation;
(3) tobacco after step (2) washing be dried process after for follow-up cigarette process production.
Described in step (3), be dried as vacuum drying; Vacuum drying adopts rotary drum vacuum dryer to be dried, and rotary speed is 10 ~ 50r/min, and drier pressure remains on 0.01 ~ 0.03MPa, and baking temperature remains on 25 ~ 40 DEG C, dry 2 ~ 4h; Preferably dry 3h under 0.015MPa, 40 DEG C of conditions.
Tobacco after step (3) is dry, preferably under 22 DEG C, relative humidity 60% condition, balance to water content in tobacco is 11% ~ 13%.
It should be noted that, the tobacco of indication of the present invention comprises the pipe tobacco or the tobacco leaf that in production of cigarettes process, use.Use tobacco harm reduction treatment process provided by the present invention, because tobacco harm reduction processing solvent has carried out preliminary extraction or degraded to the protein matter in tobacco sample, thereby after tobacco is made cigarette, can reduce the burst size of the ammonia in cigarette mainstream flue gas; Use another advantage of tobacco treatment process provided by the present invention to be, by the processing of in earlier stage tobacco being packed, can make tobacco face shaping be consistent, after soaking, being dried, do not affect follow-up production of cigarettes.Use tobacco treatment process provided by the present invention, simple flow, energy consumption is low, adapts to tobacco type extensive, has better propagation and employment and is worth.
Detailed description of the invention
For making those skilled in the art can better implement the present invention, inventor has done further tobacco harm reduction and has processed experiment, below in conjunction with embodiment the present invention will be further explained explanation.
