AI Technical Summary

Problems solved by technology

The leaf group formulas for blending are diversified, the grades of tobacco leaves used in the formula are complex, and the batches of blending processing vary greatly; at the same time, because different operators operate according to their own experience, the methods and methods are not the same. The internal physical and chemical indicators of the system cannot be controlled by scientific and reasonable methods
[0014] Therefore, the quality of tobacco leaf processing will be low, the technological indicators will not be reached, and the quality will be low, which will affect the future development prospects of the entire enterprise.

Abstract

The invention relates to a leaf wetting control system of cigarette baking product line, wherein it can use the character of cigarette leaf to realize automatic control.

Description

technical field [0001] The invention relates to a control system for a leaf conditioner in a rebaking workshop of a cigarette factory. Background technique [0002] After our research on rebaking enterprises, the information related to the research of this topic is roughly as follows: [0003] A: Leaf conditioner: [0004] There is a belt scale at the entrance of Yirun for initial flow control; [0005] There is a belt scale at the entrance of Errun for precise flow control; [0006] The control of the first moistening and the second moistening is based on the operator, and the humidification steam circuit is controlled by PID. The outlet moisture and temperature can be controlled within the required range of the process due to the operator's accumulated operating experience for many years. Different operators have different operating methods for leaf conditioners. [0007] B: Rebaking machine: the inlet is equipped with an infrared moisture meter, and the outlet is equi...
