Problems solved by technology

[0006] The purpose of the present invention is to aim at the process of drying, regaining moisture, feeding and other processes during the process of shred making and leaf threshing and redrying in current cigarette production. The outlet material temperature is high and the material temperature is constantly changing, resulting in distortion of the detected temperature, and therefore For technical problems that affect the accuracy and stability of equipment temperature control, provide a dual-temperature instrument linkage control that can detect and correct methods in a targeted manner, improve temperature detection accuracy, speed up feedback, and improve equipment temperature control accuracy and stability technology

Embodiment 1

[0031] A dual temperature instrument linkage control technology, such as figure 1 As shown, the ambient temperature and humidity are detected, and the influence of the ambient temperature and humidity on the temperature of the material detected by the online infrared temperature instrument is formed into a mathematical correction model. Consistent, can control material temperature more accurately and stably, and stabilize product quality.

[0032] Further, the implementation steps of detecting the ambient temperature and humidity are as follows:

[0033] S11. Install and inspect the online infrared thermometer, select the most representative location for the ambient temperature and humidity from the passage of the material and install the ambient temperature and humidity detector. The installation position of the ambient temperature and humidity detector is usually at the same level as the material, in the middle of the material outlet to the installation point of the infrare...

Embodiment 2

[0048] like figure 2 As shown, it is a principle diagram when the present invention is applied to the loosening and dampening link of the silk thread. Detect the ambient temperature and humidity, and form a mathematical correction model based on the influence of the ambient temperature and humidity on the temperature of the material detected by the online infrared temperature instrument. More accurate and stable control of material temperature, stable product quality.

[0049] Further, the implementation steps of detecting the ambient temperature and humidity are as follows:

[0050] S11. Install and inspect the online infrared thermometer, select the most representative location for the ambient temperature and humidity from the passage of the material and install the ambient temperature and humidity detector. The installation position of the ambient temperature and humidity detector is usually at the same level as the material, in the middle of the material outlet to the ins...

Abstract

The invention discloses a dual-thermometer linkage control technology, which detects the ambient temperature and humidity, forms a mathematical correction model based on the influence of the ambient temperature and humidity on the material temperature detected by the online infrared temperature instrument, and corrects the infrared thermometer in real time according to the mathematical correction model Test results. The beneficial effects of the present invention are: the present invention can be applied in the process of temperature control in the tobacco industry thread making line or threshing and re-baking line, including shredded leaves, shredded stem drying, re-roasting of leaves, moistening and re-moisturizing of leaves, and adding materials to moistening leaves. In this link, it can significantly improve the stability of temperature control. By improving the stability of temperature control, the quality stability of processed materials can be improved, and the level of cigarette production control can be improved.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a dual-thermometer linkage control technology, which is applied to processes that require accurate temperature control, such as drying shredded leaves, shredded stems, and redrying leaves in silk-making lines or threshing and redrying lines. Background technique [0002] It has been more than 10 years since the online infrared thermometer was introduced into the tobacco processing process, from being only used as a manual control reference at the beginning, to gradually entering the control system for closed-loop PID control. At present, online infrared thermometers are widely used in all aspects of cigarette production. [0003] In the detection of online infrared thermometer, it is necessary to eliminate the interference of steam emitted by materials, so the general installation location is about half a meter away from the exit of related process equipment. Due to t...
