Problems solved by technology

At present, the way to reduce such harmful effects is to add materials capable of absorbing such substances during the production of cigarette filters or to use tobacco leaves with low content of tobacco-specific nitrosamines as raw materials for cigarettes, and reduce them from the perspective of cigarette processing technology. The release of NAB has not been reported

Embodiment 1

[0015] In the microwave loosening process of the silk making process, the process parameters of the microwave loosening process of the key backbone brand cigarettes are used as the benchmark process parameters, and the tobacco shreds are carried out based on the benchmark process parameters, and the tobacco samples produced are blank samples; The tobacco sample is an optimized sample, and the results are as follows:

[0016] Table 1 The release amount of NAB of samples in the microwave loosening process

[0017] sample name

[0018] It can be seen from Table 1 that the release of NAB in the flue gas of the tobacco samples produced under the optimized combination of microwave loosening process parameters was 53.91% lower than that of the blank sample; the amount of NAB in the flue gas of the samples produced under the optimized process parameters release was significantly reduced.

Embodiment 2

[0020] In the loosening and regaining process of the silk making process, the process parameters of the loosening and regaining process of the key backbone brand cigarettes are used as the benchmark process parameters, and the tobacco shreds are carried out based on the benchmark process parameters, and the tobacco samples produced are blank samples; The tobacco sample is an optimized sample, and the results are as follows:

[0021] Table 2 NAB release amount of tobacco samples in the loosening and rehydration process

[0022]

[0023] It can be seen from Table 2 that the release of NAB in the tobacco samples produced under the optimized combination of loose moisture regain process parameters is 39.13% lower than that of the blank sample, and the release of NAB in the smoke of the samples produced under the optimized process parameters volume decreased significantly.

Embodiment 3

[0025] In the HT+shredding process of the silk making process, the HT+shredded drying process process parameters of the key backbone brand cigarettes are used as the benchmark process parameters, and the tobacco shreds are carried out based on this benchmark process parameter, and the tobacco sample produced is a blank sample; according to the optimized parameters in step 3 The produced tobacco samples are optimized samples, and the results are as follows:

[0026] Table 3 NAB release amount of tobacco samples in HT+drying process

[0027]

[0028] It can be seen from Table 3 that the release of NAB in the flue gas of the tobacco samples produced under the optimized combination of HT+drying process parameters was 57.39% lower than that of the blank sample; The release of NAB was significantly reduced.

[0029] In this paper, the vapor pressure is gauge pressure.

[0030] The release of NAB from the sample was tested according to the standard GB / T 23228-2008, and its Chine...

Abstract

The invention relates to a technique for processing cigarette with low NAB release. The technological parameters of main work procedures are as follows: 1) microwave loosing work procedure: microwave power is 120kW and processing time is 240s; 2) loosing dampening work procedure: vapour pressure of a water vapour nozzle is 0.3MPa, hot blast temperature is 48 DEG C, and rotating speed of barrel is 9r / min; 3) HT and cut tobacco drying work procedure: HT working vapour pressure is 0.3MPa, hot blast temperature is 85 DEG C, the aperture of a dampness damping throttle is 31%, the aperture of a hot blast throttle is 30%, and the rotating speed of barrel is 13r / min; and HT is a leaf thread heating dampening work procedure carried out by adopting a tunnel type leaf thread heating dampening machine. In the invention, technological parameters of the existing work procedure are optimized, thus effectively reducing NAB release in smoke of the obtained cigarette product.

Description

technical field [0001] The invention relates to a method for making shredded tobacco, in particular to a cigarette processing method with low NAB emission. Background technique [0002] It has been unanimously recognized by all walks of life that smoking is harmful to health. With the impetus of the World Health Organization, governments of many countries and various anti-smoking groups, the global anti-smoking movement is increasing day by day, and the tobacco industry is under increasing social pressure. The "Framework Convention on Tobacco Control" signed by the Chinese government stipulates that the Chinese government should formulate more stringent "tobacco control" laws and regulations, urging cigarette manufacturers to strictly control the main substances in cigarette smoke while reducing the amount of tar released from cigarettes. release of harmful components. In order to improve the quality and safety of cigarette products in my country, the State Tobacco Monopoly...
