Problems solved by technology

At present, the use of tobacco leaf threshing and redrying processing technology to reduce the amount of ammonia release in cigarette smoke has not been paid attention to, and there are no related patents and literature reports. Toasting method, on the premise of ensuring the style of tobacco raw material products, this method will reduce the amount of HCN released in cigarette smoke and move it to the stage of leaf threshing and redrying. and other coordination issues, which are of great value when it comes to cigarette safety

Embodiment 1

[0023] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as blank samples; among them, for the B3F tobacco leaves in a certain place in 2011, the new hot air moistening process was added, and the tobacco leaf samples produced were optimized samples. Tobacco leaf samples were loosened and rehydrated under the same conditions, shredded, and naturally air-cured, and then rolled into cigarette samples. The HCN content in smoke of the samples was detected in Table 1.

[0024] Table 1B3F optimized sample and blank sample HCN content detection results

[0025]

[0026] It can be seen from Table 1 that under the new treatment process conditions, the HCN content in the flue gas of the tobacco samples produced by B3F is 13.29% lower than that of the blank samples, which has a significant effect of reducing the HCN content.

Embodiment 2

[0028] Tobacco leaves of all grades, the tobacco leaf samples produced according to the existing threshing and re-baking process parameters are used as blank samples; B3F Tobacco leaves from a certain place, adjust the process parameters according to the combination of optimized processing process parameters, and keep the other process process parameters unchanged. The tobacco leaf samples produced are optimized samples; Cigarette samples were produced, and the HCN content in the smoke of the samples was detected in Table 2.

[0030]

[0031]

[0032] It can be seen from Table 2 that in the threshing air separation process, the HCN content in the flue gas of the lower tobacco leaves X3F produced under the optimized process parameter combination was 10.95% lower than that of the blank sample; The content of HCN in the flue gas of the produced tobacco sample was 8.82% lower than that...

Embodiment 3

[0034] The tobacco leaf sample produced according to the existing threshing and redrying process parameters is used as a blank sample; in the tobacco sheet redrying process, the lower 2011 X3F tobacco leaves, the middle 2011 C3L tobacco leaves, and the upper 2011 B3F tobacco leaves, The process parameters were adjusted according to the combination of optimized processing process parameters, and the process parameters of other processes were kept unchanged, and the tobacco leaf samples produced were optimized samples; the tobacco leaf samples of each group were loosely rehydrated, shredded, and naturally air-cured under the same conditions, and the cigarette samples were rolled. The detection of HCN content in flue gas of the samples is shown in Table 3.

Abstract

The invention discloses a threshing and re-drying method capable of lowering the release amount of HCN. The method mainly comprises a threshing air separation procedure and a tobacco leaf re-drying procedure. Hot air leaf moisturizing procedures, namely the primary hot air leaf moisturizing procedure and the secondary hot air leaf moisturizing procedure, are added before the threshing air separation procedure, and the temperature for hot air leaf moisturizing is eighty to one hundred and twenty DEC G. Due to the fact that the hot air leaf moisturizing procedures are added before the threshing air separation procedure, the release amount of HCN in flue gas can be effectively lowered on the premise that the style of cigarettes is maintained.

Description

technical field [0001] The invention belongs to the field of cigarette raw material processing, and in particular relates to a leaf threshing and redrying method for reducing HCN release. Background technique [0002] HCN is one of the important environmental pollutants. Its poisoning mechanism is mainly due to the combination of cyanide ions and ferric iron in oxidative cytochrome oxidase, which blocks the electron transfer of ferric iron in the oxidation process, so that tissue cells cannot use it. Oxygen, the formation of internal suffocation, coma, respiratory arrest, severe death within a few minutes. HCN pollution mainly comes from industries that produce cyanide waste such as synthesis, mining metallurgy, electroplating, textiles, pesticides, plastics, and synthetic rubber. Some plants also contain cyanide in nature, mainly in the form of cyanogenic glycosides, such as amygdalin in bitter almonds and lima beans, zeerin in sorghum, linamarin in cassava, and prunes in ...
