Abstract

The invention discloses a seven-stage marching type tobacco leaf baking method, relates to a tobacco leaf processing and curing method, in particular to an improved staged tobacco leaf baking method. According to the method, baking is divided into seven stages, baking methods and parameters of the stages are reasonably designed; in the temperature rise period, the stage temperature can be systematically increased; in the aspect of wet ball control, a humidity elimination task can be reasonably carried out; in addition, in the later tobacco leaf baking period, the sixth stage is set, and a large space is provided for increasing synthesis of aroma components of tobacco leaves. The seven-stage marching type tobacco leaf baking method is simple and easy to master, easy to operate, reasonable in target setting in all stages, better in quality of appearance of the baked tobacco leaves and capable of improving the tobacco leave baking quality, and the percent of pass of the method is increased compared with that of a conventional tobacco leaf baking method.

Description

technical field [0001] The invention relates to a method for processing and modulating tobacco leaves, in particular to an improved method for curing tobacco leaves in stages. Background technique [0002] At present, there are many types of tobacco leaf curing processes, and the curing methods are different. Most of the processes have a small step in the temperature rise and stabilization stage. In addition, it is impossible to closely monitor at night, and the temperature drop phenomenon is prone to occur during baking, and the loss of tobacco leaf baking is relatively large. Big. In addition, the existing conventional process is prone to high and low parameters during the temperature rise and stabilization stage, which is not systematic. Even if the temperature and humidity are controlled accurately, it will also affect the yellowing and color fixation of tobacco leaves. Contents of the invention [0003] In order to overcome some existing curing problems, the purpose ...
