Technology for reducing harmful ingredients in smoke

Abstract

The invention relates to a technology for reducing harmful ingredients in smoke. The technology comprises processes as follows: step one, backflow elution of tobacco: a used solvent is normal hexane or 95% ethanol, and the tobacco is subjected to backflow elution for 10-60 minutes; step two, solvent recovery: the solvent on the tobacco is removed by using superheated steam; and step three, tobacco structure repairing: glycerin or propylene glycol is mixed with water or ethyl alcohol to prepare a repairing solution, the use amount of glycerin or propylene glycol is 1%-15% of tobacco in percentage by weight, and the repairing solution is uniformly sprayed on the tobacco for repairing for 2-72 hours. According to a cigarette prepared by tobacco treated by the technology, the harmful ingredients in the smoke can be remarkably reduced, and the safety of the cigarette is guaranteed.

Description

technical field [0001] The invention relates to the technical field of cigarette production, in particular to a new tobacco treatment process capable of significantly reducing harmful components in cigarette smoke. Background technique [0002] With the in-depth implementation of the State Tobacco Monopoly Administration's strategy of "promoting tobacco through science and education", the overall quality of cigarette products in my country has been significantly improved, and the tar content of cigarettes has decreased year by year. The precursors of harmful components in tobacco leaves have a greater impact on the safety of cigarettes. The usual method is to use filters or compound tobacco leaves to filter smoke or reduce the human body’s inhalation of smoke from tobacco leaves. Cigarette quality is greatly affected, production costs are virtually increased, and consumers' acceptance is also low. However, through the improvement or innovation of cigarette processing technol...

AI Technical Summary

Problems solved by technology

[0006] Using the above methods, the processed tobacco is dry and brittle to varying degrees, and the processing resistance is greatly reduced. At the same time, the balance of the chemical components of the tobacco is broken, and the sensory quality of the smoke after combustion is greatly reduced.
