Method for controlling shrinking percentage of tobacco lamina

The invention relates to a method for controlling the shrinking percentage of tobacco lamina. The method comprises the following steps: determining the shrinking percentage of a tobacco lamina re-drying process; determining the moisture content of the raw material tobacco leaves under the same grade; establishing shrinkage rate control models of the raw material tobacco leaves about different moisture contents, combining the shrinkage rate control models of different moisture contents to form a shrinkage rate control model, and storing the shrinkage rate control model; the detection system detects current raw material tobacco leaf information and transmits the current raw material tobacco leaf information to the control system, and the control system uses a key control index correspondingto the shrinking percentage control model of the corresponding moisture content to control and adjust parameters according to the corresponding raw material tobacco leaf information. According to thetechnical scheme, as long
