Problems solved by technology

[0003] At present, the moisture meter at the outlet of cut tobacco in tobacco companies is generally installed on the conveyor belt about 3 meters away from the outlet of cut dry. , and under different environmental and climatic conditions, the water dispersion loss value of shredded tobacco is inconsistent, resulting in fluctuations in the moisture content of shredded tobacco before flavoring, which makes it difficult to control the moisture content of finished shredded tobacco after flavoring

Abstract

The invention discloses a cut tobacco drying outlet moisture content control method and device. The method includes that a first moisture detector detects moisture content of cut tobacco before primary blending at a preset time interval and sends a moisture content detection value of the cut tobacco before primary blending to a control signal generator; the control signal generator generates a first control signal according to the moisture content detection value of the cut tobacco before primary blending and target moisture content of the cup tobacco before primary blending; a PID controller performs PID control processing according to the first control signal to generate a second control signal; a hot air quantity control valve adjusts hot air quantity according to the second control signal to adjust the moisture content of the cut tobacco at a dried cut tobacco outlet so as to adjust the moisture content of the cut tobacco on a conveying belt before primary blending. By adding a moisture detector on the conveying belt before primary blending, the moisture content of the cut tobacco before perfuming is stabilized, and accurate control on the moisture content of finished cut tobacco is realized.

Description

Technical field [0001] The invention relates to the field of tobacco production, in particular to a method and device for controlling the moisture content of the tobacco drying outlet. Background technique [0002] The moisture content of cut tobacco drying outlet is one of the key quality indicators in the production process of cigarette cut. This quality index will affect the moisture content of the flavoured cut tobacco for export, and plays an important role in whether the moisture content of the finished tobacco is qualified. [0003] At present, the moisture meter at the outlet of the tobacco company is generally installed on the conveyor belt about 3 meters from the outlet of the tobacco. At this time, the temperature of the tobacco is about 60℃. During the transportation of the tobacco, the moisture of the tobacco will be lost as the temperature decreases. In addition, under different environmental and climatic conditions, the loss of water dispersion of cut tobacco is inc...
