Method for preparing aromatized tar reduction cut tobaccos

Abstract

The invention discloses a method for preparing aromatized tar reduction cut tobaccos. Burley tobacco flakes and flue-cured tobacco flakes are uniformly mixed according to a certain proportion and then cut into cut tobaccos on a tobacco cutting machine, moisture in the cut tobaccos is controlled within the range of process requirements by the aid of working hot air with stable temperature in an HDT (heat distortion temperature) hot air pipeline after the cut tobaccos are fed and humidified by a tobacco wetting machine, and the cut tobaccos are packed and stored after cooled and applied with surface aroma, so that finished cut tobaccos applicable to low-tar cigarettes are produced. The method is ingenious in process combination, can simultaneously meet two requirements of the cigarettes for tar reduction, harm reduction and aroma enhancement and supplement, and can be used as a base for researching and developing the low-tar cigarettes.

Description

technical field [0001] The invention belongs to the technical field of cigarette preparation and processing, and in particular relates to a method for preparing shredded tobacco with low tar content and a flavoring effect to improve the quality of cigarettes. Background technique [0002] With the continuous improvement of consumers' requirements for cigarette smoking quality and safety, low-tar cigarettes have gradually become the mainstream development trend in the field of cigarette manufacturing. At present, various tobacco companies are researching and applying methods to achieve low tar in cigarettes, such as increasing the length of cigarette filter tips, using high-permeability cigarette filter rods, adopting laser drilling technology, and tobacco expansion technology. These methods can reduce the tar content of shredded tobacco to a certain extent, but in the process of using these technologies, with the reduction of tar content in shredded tobacco of cigarettes and...

AI Technical Summary

Problems solved by technology

These methods can reduce the tar content of shredded tobacco to a certain extent, but in the process of using these technologies, with the reduction of tar content in shredded tobacco of cigarettes and the reduction of total particulate matter in smoke, the aroma of cigarettes is also greatly weakened, causing consumers Physical dissatisfaction during cigarette smoking

[0003] In the existing technology, tobacco expansion technology such as HDT hot air duct drying process can restore the volume of tobacco leaves that have lost water and shrink to the volume of fresh tobacco leaves, greatly increasing the filling performance of tobacco, reducing the loss of cigarette raw materials while reducing Increase the tar content of cigarettes, thereby improving smoking safety; the sugar content of Burley tobacco is low, generally not exceeding 2%, but the content of potassium, calcium, magnesium and other minerals is high, and the tobacco leaf tissue is loose, and the amount of tar released by burning is lower than The aroma substances of flue-cured tobacco are higher than those of flue-cured tobacco. Mixing Burley tobacco and flue-cured tobacco in proportion can play a role in supplementing the aroma substances of cigarettes; but so far, there has been no report on the combination of these two processes
