Processing technology of low-quality flue cured tobacco leaf

Abstract

The invention discloses a processing technology of low-quality flue cured tobacco leaf. Technologies of pine flake thread-cutting and leaf and thread charging are adopted, namely a charging device at the back end of a loose moisture-regain machine is utilized for charging tobacco sheets, and then charging the leaf threads after thread-cutting; components such as moisture-maintaining agent are added to tobacco sheet charging solution, the sheet charging proportion is 1%-3%, and components such as style reinforcing agent are added in leaf thread charging solution, wherein the thread charging proportion is 3%-5%, and the water adding proportion is 7%-10%; with a leaf thread baking and drying technology, a baking machine adopts drum-type construction, a material inlet end and a material outlet end adopt gas lock feeding control, hot source supply adopts two heat transfer manners of cylinder wall heat transfer and combustion furnace hot wind convection, and the processing time of a baking and drying machine is set to be 10-12 minutes. Aiming at the processing characteristics of the low-quality flue cured tobacco leaf, the processing technology of the low-quality flue cured tobacco leaf improves the sensory quality of cigarette, and is more pertinent in the procedure of the processing technology, more reasonable in the processing manner and more flexible in parameters of the processing technology.

Description

technical field [0001] The invention relates to a tobacco processing technology, in particular to a processing technology for low-quality flue-cured tobacco leaves. Background technique [0002] The flue-cured cigarette formula is composed of different grades of tobacco leaves in a certain proportion, and is processed through multiple processes such as leaf making, shredded leaf making, blending and flavoring, and finally rolled into cigarettes. Low-quality flue-cured tobacco leaves are an indispensable part of the flue-cured cigarette formula. Usually, their quality characteristics can be summarized as follows: medium-low aroma, medium-poor aroma, large miscellaneous gas-less, high-irritating . Based on the above understanding of the quality characteristics of low-quality flue-cured tobacco leaves, in the actual cigarette processing process, the processing of low-quality flue-cured tobacco leaves generally adopts the following processing technology: loose moisture resurgen...

AI Technical Summary

Problems solved by technology

However, for cigarette manufacturing enterprises at this stage, there are still outstanding problems in the processing of low-quality flue-cured tobacco leaves, such as "similar processing process", "unreasonable selection of processing methods", and "small adjustable range of process parameters":

Due to the large differences in the physical and chemical properties of low-quality flue-cured tobacco leaves and other high-quality flue-cured tobacco leaves, the existing processing technology cannot adopt targeted processing for the quality characteristics of low-quality flue-cured tobacco leaves. deal with

[0008] (2) The choice of processing method is unreasonable

Low-quality flue-cured tobacco leaves are often air-dried in the shred process, and the heat source is only the heating of the combustion furnace. Due to the characteristics of short drying time and high processing intensity during the drying process, the low-quality flue-cured tobacco after treatment The aroma of tobacco leaves is greatly lost, the smell of charred is obvious, the Maillard reaction is not sufficient, and the smoking taste of cigarettes is poor

[0009] (3) Single process parameter setting

For low-quality flue-cured tobacco leaves, high-temperature treatment conditions are used in the selection of processing parameters for shredded tobacco leaves, and the adjustment range of process parameters is small, and the quality of tobacco leaves drops significantly after processing.
