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 136KW and processing time 320s, and the process parameters of other processes were unchanged, and the production obtained The tobacco samples of the two samples are optimized samples;

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

[0020]

[0021] It can be seen from Table 1 that the crotonaldehyde content in the flue gas of the tobacco samples produced under the combination of microwave loose optimization process parameters is 15.72% lower than that of the blank sample, which has an obvious effect of reducing the crotonaldehyde content.

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 0.3MPa, the return air temperature of 48°C, and the cylinder speed of 9r / min The process parameters were adjusted in combination, and the process parameters of the other processes were kept unchanged. The tobacco samples produced were optimized samples;

[0025]

[0026]

[0027] It can be seen from Table 2 that the content of crotonaldehyde in the flue gas of the tobacco samples produced under the combination of loose moisture regain optimization process parameters is 14.64% lower than that of the blank sample, which has an obvious effect of reducing th...

Embodiment 3

[0029] The tobacco sample produced according to the established cigarette shred process parameters is used as a blank sample; in the HT + shred drying process, the working steam pressure of HT is 0.60MPa, the hot air temperature is 85°C, the moisture exhaust damper opening is 53%, and the hot air damper opening is 70 %, cylinder speed 9r / min optimized processing parameters combined to adjust the process parameters, the remaining process parameters remain unchanged, the tobacco sample produced is the optimized sample; the detection of the crotonaldehyde content in the smoke of the two samples is shown in Table 3.

[0031]

[0032] It can be seen from Table 3 that the content of crotonaldehyde in the flue gas of the tobacco samples produced under the combination of HT+shred drying optimization process parameters is 56.01% lower than that of the blank sample...

Abstract

The invention relates to a processing method of cigarettes with low crotonaldehyde content, and the specific process parameters of the main process steps are as follows: 1) the microwave loosening process step: the microwave power is 136KW, and the processing time is 320s; 2) the loosening and conditioning process step: the steam pressure of a steam and water nozzle is 0.3MPa, the temperature of return air is 48 DEG C, and the rotational speed of a cylinder body is 9r/min; 3) the HT and cut tobacco drying process step: the HT working steam pressure is 0.60MPa, the temperature of hot air is 85 DEG C, the opening degree of a moist air removing door is 53%, the opening degree of a hot air door is 70%, and the rotational speed of the cylinder body is 9r/min; and the HT is the cut tobacco temperature-increasing and moisture-increasing process step which is carried out by adopting a tunnel type cut tobacco temperature-increasing and moisture-increasing machine. The processing method can effectively reduce the content of crotonaldehyde in smoke gas of the prepared cigarette products through optimal combination of process parameters of the existing process steps.

Description

technical field [0001] The invention relates to a cigarette processing method with low crotonaldehyde content, in particular to a key process method for making shredded cigarettes with low crotonaldehyde 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 Mo...
