Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] figure 1 Among them, steam pressure gauge, steam flow meter, water adding flow meter, infrared thermometer and infrared moisture meter are installed on the blade dampening machine to detect steam pressure, steam flow, steam valve opening, water adding valve opening, water adding flow, Outlet temperature, outlet moisture indicators, and send these indicators to the PLC controller.

[0013] The PLC controller is directly connected to the detection element and the control element, collects various detection data in real time, and divides the signal of the process index into two channels, one of which is sent to the monitoring machine. After analyzing the results, the results that meet the requirements are sent to the server to form empirical data. Control the model, and alarm if the data does not meet the requirements. The server sends the data to...

Abstract

The invention discloses a modeling control method during tobacco leaves lamping processing in tobacco shred production, which solves the problem that the product quality problem is influenced because the tobacco leaves lamping fluctuation is big in tobacco shred production and the modeling control method has advantages of automatic studying capability, increased control accuracy and increased product quality. A detection device is set on a production line and the detected process index is sent to a PLC controller and the PLC controller divides the process index into two paths, wherein one path is sent to a monitor to analyze the detected process index and the data, which is up to the mustard, is sent to a server to form an experience database and the data is sent to the monitor and the PLC controller by the database and the data, which is not up to the mustard, sends alarm signal; another path of the process index data is subjected to negative feedback PIC operation by the PLC and then integrated with the experience data to form a control command to control the operation of the damping device.

Description

technical field [0001] The invention relates to a modeling control method for the leaf moisture resurgence process in shredded tobacco production. Background technique [0002] In the production process of shredded tobacco, leaf rehydration is a relatively special process. In this process, the processed raw material is tobacco leaves arranged by type without blending. And different types of tobacco leaves have different reactions to steam and water because of their different attributes. In the same formula (brand), the production sequence of various tobacco leaves is the same. At present, PID negative feedback control is generally used for tobacco leaf remoisture. In the production process of the same tobacco leaf, the effect is better and the stability requirement can be met. However, when different tobacco leaves are switched and production starts and ends, the fluctuation is large, which affects the production index. Contents of the invention [0003] The purpose of t...
