Embodiment Construction

[0050] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0051]Aiming at the inaccurate and uneven control of outlet moisture content in thin-plate dried shreds, which may easily cause inconsistencies in the quality of tobacco leaves within or between batches and affect the quality of tobacco, the invention provides a method for controlling the moisture content of shredded tobacco in thin-plate dried shreds In the same batch, the PID feedback control model is set to adjust the hot air speed to control the outlet moisture content, which solves the problem of inaccurate and uneven control of the outlet moisture content of the existing sheet-dried shreds, and can improve the performance of each batch of thin-dried shreds. The consistency of uniformity improves the quality...

Abstract

The invention provides a method and a system for controlling tobacco shred water content of sheet cut tobacco drying. The method comprises the following steps: setting hot air temperature of the sheetcut tobacco drying according to a set value, and setting a target value of outlet water content of the sheet cut tobacco drying; obtaining an actual measurement value of the outlet moisture content of the sheet cut tobacco drying process, and obtaining a target deviation value of the outlet moisture content according to the target value and the actual measurement value; and a PID feedback controlmodel is established and used for adjusting the hot air speed according to the target deviation value so as to carry out feedback control over the outlet moisture content, and the outlet moisture content of the thin-plate cut tobaccos in the batch is controlled according to the target value. According to the invention, the uniformity consistency of thin plate cut tobacco drying in each batch canbe improved, and the quality control capability in the production process is improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method and system for controlling the water content of shredded tobacco dried with thin plates. Background technique [0002] In the process of tobacco processing, the drying process is the most important part of the silk processing. The thin plate drying machine is used for drying and dehydration. In the thin plate drying process, the outlet moisture is often adjusted by the cylinder temperature. By adjusting the temperature of the cylinder Set the value to change the opening of the steam valve, and then adjust the outlet moisture. However, in the actual production process, the temperature of the hot air is controlled by adjusting the opening of the hot air door to ensure that the temperature of the hot air remains in a relatively stable range. Silk cannot be subjected to appropriate high-temperature air drying treatment in time. Ultimately, the moisture content o...
