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 248s, and the process parameters of other processes were unchanged, and the production obtained The tobacco samples of the two samples are optimized samples; the detection of smoke ammonia content of the two samples is shown in Table 1.
[0019] Table 1 The detection results of ammonia content in samples optimized for microwave loosening process and blank samples
[0020]
[0021] It can be seen from Table 1 that the ammonia content in the flue gas of the tobacco sample produced under the microwave loose optimization process parameter combination is 4.92% lower than that of the blank sample, which has an obvious effect of reducing the ammonia 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;
[0024] Table 2 Detection results of ammonia content in the optimized sample and blank sample in the loosening and moisture regaining process
[0025]
[0026] It can be seen from Table 2 that the ammonia content in the flue gas of the tobacco samples produced under the combination of loose moisture regain optimization process parameters is 8.82% lower than that of the blank sample, which has an obvious effect of reducing ammonia content.
Embodiment 3
[0028] The tobacco sample produced according to the established cigarette shred process parameters is used as a blank sample; in the HT+shredded drying process, the working steam pressure is 0.40MPa, the hot air temperature is 135°C, the moisture exhaust damper opening is 80%, and the hot air damper opening is 30%. %, cylinder speed 13r / min low HCN content optimization process parameters combination adjustment process parameters, the rest of the process process parameters remain unchanged, the tobacco sample produced is the optimized sample; the smoke ammonia content detection of the two samples is shown in Table 3.
[0029] Table 3 HT + silk drying process optimized sample and blank sample ammonia content detection results
[0030]
[0031] It can be seen from Table 3 that the ammonia content in the flue gas of the tobacco samples produced under the combination of HT+shred drying optimization process parameters is 46.52% lower than that of the blank sample, which has an obv...
