The invention relates to a method for controlling the shrinkage rate of lamina, which comprises determining the shrinkage rate of the rebaking process of lamellae; determining the moisture content of raw tobacco leaves at the same level; and respectively establishing shrinkage rate control models for different moisture contents of raw tobacco leaves , and combine the shrinkage rate control models with different moisture contents to form the shrinkage rate control model and store it; the detection system detects the current raw tobacco leaf information and transmits it to the control system, and the control system according to the corresponding raw tobacco leaf information, Use the key control indicators corresponding to the shrinkage rate control model of the corresponding water content to perform parameter control adjustments. According to the technical solution, as long as the shrinkage rate of the recured tobacco sheet is determined, the control index corresponding to the corresponding shrinkage rate model can be adjusted according to different raw material tobacco leaf parameters, so as to ensure the stability of the shrinkage rate of the recured sheet tobacco.
Description
technical field [0001] The invention belongs to the technical field of threshing and redrying control in the silk making process, in particular to a method for controlling the shrinkage rate of tobacco flakes. Background technique [0002] Leaf threshing and redrying is the first process in the silk-making process of cigarette industrial enterprises, and redrying sheet tobacco is the basic raw material for cigarette industrial enterprises. The process of leaf threshing and rebaking is roughly divided into "leaf moistening process---leaf threshing process---rebaking process". The rate of large and medium slices of finished leaf threshing and rebaking tobacco is an important indicator for evaluating rebaking enterprises. It is also one of the indicators that the cigarette industry is more concerned about, because the ratio of large and medium sheets of threshed and recured tobacco is closely related to the whole cut ratio and filling ratio of cigarette shreds. By analyzing th...
