Expansion process for cut tobacco

Abstract

The invention discloses an expansion process for cut tobacco and relates to the technical field of tobacco processing. The expansion process includes: humidifying the cut tobacco, impregnating the cut tobacco, feeding the cut tobacco, expanding and forming the cut tobacco, regulating the cut tobacco, and discharging the cut tobacco. The expansion process has the advantages that the aroma substances with medium and high boiling points in the cut tobacco can be effectively kept, a good cut tobacco expansion effect is achieved, and few scraps are achieved; the method is high in safety, free of pollution, free of residues, capable of effectively increasing the expansion rate of the cut tobacco, capable of greatly lowering the amount of the cut tobacco wrapped in each cigarette, and capable of evidently lowering the tar content in cigarettes.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a shredded tobacco expansion processing technology. Background technique [0002] Shredded tobacco needs to be expanded during the process of being processed into cigarettes. Shredded tobacco is expanded by adding a certain medium to part of the shredded tobacco used in cigarettes and then performing high-temperature treatment to expand the volume of shredded tobacco. This can not only reduce the production cost of cigarettes, but also reduce the tar in cigarettes. reduce the damage of smoking to the body. The existing cut tobacco expansion method is relatively traditional, resulting in insufficient expansion rate of cut tobacco, the amount of shredded tobacco wrapped in each cigarette is not reduced too much, and the reduction of tar in cigarettes is not obvious enough. Contents of the invention [0003] The technical problem to be solved by the present invention i...
