Embodiment 1

[0016] Tobacco samples produced according to the established cigarette shred process parameters were used as control samples; in the microwave loosening process, the process parameters were adjusted according to the combination of microwave power 121KW and processing time 240s. Tobacco samples are optimized samples; the Cd content detection of the two samples is shown in Table 1.

[0017] Table 1 Detection results of Cd content in samples optimized for microwave loosening process and control samples

[0018] sample name

[0019] It can be seen from Table 1 that the Cd content in the tobacco samples produced under the combination of microwave loosening optimization process parameters is 15.17% lower than that in the control sample, which has an obvious effect of reducing Cd content.

Embodiment 2

[0021] Tobacco samples produced according to the established cigarette shred process parameters were used as control samples; in the loosening and 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 70°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 produced were optimized samples; the Cd content detection of the two samples was shown in Table 2.

[0022] Table 2 Detection results of Cd content in the optimized sample and control sample in the loosening and moisture regaining process

[0023] sample name

[0024] It can be seen from Table 2 that the Cd content in the tobacco samples produced under the loose moisture regain optimization process parameter combination is 7.45% lower than that in the control sample, which has an obviou...

Embodiment 3

[0026] Tobacco samples produced according to the established cigarette shredded process parameters were used as control samples; in the HT+shredded drying process, the working steam pressure of HT was 0.6MPa, the hot air temperature was 135°C, the moisture exhaust damper opening was 80%, and the hot air damper opening was 30 %, cylinder speed 13r / min optimized processing parameters combined to adjust the process parameters, the remaining process parameters remain unchanged, the tobacco samples produced are optimized samples; the Cd content detection of the two samples is shown in Table 3.

[0027] Table 3 Cd content test results of HT+ silk drying process optimized samples and control samples

[0028]

[0029] It can be seen from Table 3 that the Cd content in the tobacco samples produced under the combination of HT+shred drying optimization process parameters is 3.77% lower than that of the control sample, which has a significant effect of reducing Cd content.

Abstract

The invention provides a method for processing cigarettes with low content of heavy metal Cd, and belongs to the technical field of cigarette processing methods. The method comprises the following procedures: microwave loosening, loose rewetting, heating and moistening of blades, leaf wetting and material charging, leaf storage, cutting, HT and drying of cut tobacco, fragrance addition, cut tobacco storage and coiling and wrapping; the process parameters of the microwave loosening procedure is that: microwave power is 121 kilowatts and the processing time is 240 seconds; the process parameters of the loose rewetting procedure is that: the vapor pressure of gas and water nozzles is 0.3MPa, the air-returning temperature is 70 DEG C and the rotary speed of the cylinder body is 13r / min; and the process parameters of the HT and drying of cut tobacco is that: the working vapor pressure of HT is 0.6MPa, the hot air temperature is 135 DEG C, the opening degree of the moisture-discharging air door is 80 percent, the opening degree of the hot air door is 30 percent and the rotary speed of the cylinder body is 13r / min. By optimizing the process parameters, the heavy metal Cd content of cigarettes is reduced, and the advantages of the method in lowering the heavy metal Cd content of cigarettes are affirmed.

Description

technical field [0001] The invention relates to the technical field of cigarette processing methods, in particular to a cigarette processing method with low heavy metal content Cd. Background technique [0002] Heavy metals not only have a great impact on the yield and quality of flue-cured tobacco, but also have a huge impact on smokers and the environment. Flue-cured tobacco is a special economic crop with the main purpose of smoking. When the tobacco leaves contain excessive heavy metals, the heavy metals will enter the human body through the mainstream smoke during the smoking process, causing potential harm to the human body. The content of inorganic elements in tobacco and flue gas is very low, but harmful elements such as As, Cd, Cr, Hg, Pb, Se, Ni have accumulated toxicity in the human body. Among the 107 harmful components of cigarette smoke reported by the United States in 1989, As, Cd, Cr, Pb, Ni, Cu, Hg, etc. were listed. In 1990, Hoffman also listed As, Cd, Cr,...
