Embodiment 1

[0018] The tobacco sample produced according to the established cigarette shred process parameters was used as a blank sample; in the microwave loosening process, the process parameters were adjusted according to the combination of microwave power 120KW and processing time 240s, and the process parameters of other processes were unchanged, and the production obtained The tobacco samples of the two samples were optimized samples; the detection of benzo[a]pyrene content in the smoke of the two samples is shown in Table 1.

[0019] Table 1 Detection results of benzo[a]pyrene content in samples optimized for microwave loosening process and blank samples

[0020]

[0021] It can be seen from Table 1 that the content of benzo[a]pyrene in the flue gas of tobacco samples produced under the combination of microwave loosely optimized process parameters is 8.27% lower than that of the blank sample, which has an obvious effect of reducing the content of benzo[α]pyrene .

Embodiment 2

[0023] Tobacco samples produced according to the established cigarette shred process parameters were used as blank samples; in the loosening and moisture regaining process, the optimized processing parameters were based on the steam pressure of the steam and water nozzles of 0.1MPa, the return air temperature of 60°C, and the cylinder speed of 13r / min The process parameters were adjusted in combination, and the process parameters of the other processes were kept unchanged. The tobacco samples obtained from the production were optimized samples;

[0025]

[0026] It can be seen from Table 2 that the content of benzo[a]pyrene in the flue gas of the tobacco sample produced under the combination of loose moisture recovery optimization process parameters is 11.03% lower than that of the blank sample, which has an obvious effect of reducing the...

Embodiment 3

[0028] Tobacco samples produced according to the established cigarette shredded process parameters are used as blank samples; in the HT+shredded drying process, the working steam pressure of HT is 0.50MPa, the hot air temperature is 85°C, the moisture exhaust damper opening is 55%, and the hot air damper opening is 70 %, cylinder rotating speed 9r / min optimization process parameters combination adjustment process parameters, the remaining process process parameters remain unchanged, the tobacco sample produced is the optimized sample; the smoke benzo[a]pyrene content detection of the two samples is shown in the table 3.

[0029] Table 3 Detection results of benzo[a]pyrene content in samples optimized for HT+drying process and blank samples

[0030]

[0031] It can be seen from Table 3 that the content of benzo[a]pyrene in the flue gas of the tobacco samples produced under the combination of HT+drying optimized process parameters was 12.44% lower than that of the blank sampl...

Abstract

The invention provides a processing technology of cigarette for reducing a benzo(a)pyrene content. Specific technological parameters of main procedures are as follows: 1) microwave loosening procedure: microwave power is 120kW and processing time is 240s; 2) loosening and conditioning procedures: steam pressure of vapor and water nozzles is 0.1MPa, return air temperature is 60 DEG C and revolving speed of a cylinder is 13r / min; and 3) HT and tobacco drying procedures: operating steam pressure in HT is 0.50MPa, hot-air temperature is 85 DEG C, opening of moisture-discharging door is 55%, opening of hot-air door is 70%, and revolving speed of the cylinder is 9r / min, wherein, HT refers to the tobacco heating and dampening procedure by a tunnel tobacco heating and dampening machine. The processing technology of the invention helps effectively lower the benzo(a)pyrene content in fume of the obtained cigarette product by optimal combination of the technological parameters in the existing procedures.

Description

technical field [0001] The invention relates to a cigarette processing method with low benzo[a]pyrene content, in particular to a key cigarette shred-making process method with reduced benzo[a]pyrene content. Background technique [0002] The two guidelines of "prevention of exposure to tobacco smoke" and "control and disclosure of tobacco ingredients" in the "Framework Convention on Tobacco Control" require governments to formulate more stringent "tobacco control" laws and regulations, urging cigarette manufacturers to reduce cigarette tar emissions At the same time, it is necessary to strictly control the release of the main harmful components in cigarette smoke, further increasing the pressure on the industry to reduce harm and reduce coke. Smoking and health are the main challenges facing the tobacco industry, and reducing harm and coke is related to the survival of the tobacco industry And development. [0003] In order to solve these problems, the State Tobacco Monopo...
