Embodiment 1

[0022] 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 ammonia content of flue gas in the samples is shown in Table 1.

[0026] It can be seen from Table 1 that the ammonia content in the flue gas of the tobacco samples pr...

Embodiment 2

[0028] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as blank samples; Add the same proportion of biological agent aqueous solution, the biological agent is composed of Bacillus subtilis, Bacillus amyloliquefaciens, and Bacillus circulans, according to the mass percentage of 1:2:2, and use water as a solvent to prepare a 0.8‰ biological agent Aqueous solution, the content of Bacillus subtilis in biological preparations is 1×10 13 CFU / g, Bacillus amyloliquefaciens bacteria content 1×10 11 CFU / g, Bacillus circulans content 1×10 11 CFU / g; the technological parameters of the other processes remain unchanged, and the tobacco leaf sample obtained from production is the optimized sample; the cigarette sample is rolled after aging under the same conditions, loosening and rehydration, shredding, and natural drying under the same conditions. The detection of ammonia content in the smoke of the samples is shown in Table ...

Embodiment 3

[0034] The tobacco leaf samples produced according to the existing threshing and redrying process parameters were used as blank samples; Add the same proportion of biological agent aqueous solution, the biological agent is composed of Bacillus subtilis and Bacillus amyloliquefaciens, according to the mass percentage of 2:1, using water as a solvent, prepare a 1.5‰ biological agent aqueous solution, the biological agent contains Bacillus subtilis bacteria Volume 1×10 14 CFU / g, Bacillus amyloliquefaciens bacteria content 1×10 12CFU / g; the technological parameters of the other processes remain unchanged, and the tobacco leaf sample obtained from production is the optimized sample; the cigarette sample is rolled after aging under the same conditions, loosening and rehydration, shredding, and natural drying under the same conditions. The detection of ammonia content in the smoke of the samples is shown in Table 3, and 2% in the table means that the addition amount of the biologica...

Abstract

The invention discloses a redrying and alcoholizing method for reducing the release amount of ammonia. The redrying and alcoholizing method comprises the tobacco sheet redrying procedure and the tobacco sheet alcoholizing procedure. The alcoholizing procedure comprises the step that an alcoholizing agent is added into redried tobacco leaves, wherein the alcoholizing agent is a water solution of a biological agent and the biological agent is one or more of bacillus subtilis, bacillus megaterium, bacillus circulans and freeze-dried bacillus amyloliquefaciens powder. In the method, the biological agent is added to serve as the alcoholizing agent, degradation and conversion of the ammonia in tobacco leaf raw materials can be effectively improved in the tobacco leaf alcoholizing process, the process of reducing the release amount of the ammonia in cigarette smoke is realized in the threshing redrying and alcoholizing stage in advance, the threshing redrying process and the alcoholizing process are organically combined, and the redrying and alcoholizing method for reducing the release amount of the ammonia has important theoretical significance and practical application value.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a method for redrying and aging with reduced ammonia release. Background technique [0002] Ammonia is an alkaline gas in the atmosphere, mainly derived from biodegradation in the soil. Amino acids, proteins, nitrates and ammonium salts in tobacco are the precursors of ammonia in cigarette smoke. In cigarettes, ammonia not only affects the smoking quality of cigarettes, but also stimulates the visual and respiratory systems of the human body. Long-term inhalation will cause serious harm to the human body. In 2009, the Zhengzhou Tobacco Research Institute led a study on the cigarette smoke hazard index of Chinese-style cigarettes. Among the 29 harmful components in mainstream cigarette smoke, 7 representative components were selected as cigarette hazard evaluation indicators. Ammonia is one of them. Therefore, research on reducing the amount of ammonia released in ...
