Problems solved by technology

[0003] According to the investigation of the current production situation, there are the following problems: (1) External factors: only part of the company’s raw material storage is a constant temperature and humidity warehouse, and most of the raw materials are stored in natural environment warehouses. The moisture content of raw materials fluctuates greatly. The moisture is between 8%-14%, and the difference between the lowest moisture and the highest moisture in the batch is about 6%
(2) Internal factors: There is no moisture detection point in the front-end process of the workshop from the elevated warehouse to the discharge, vacuum re-moisture, and loose re-moisture. As a result, the moisture information of the tobacco leaves cannot be obtained during the path of more than 300 meters and the three production positions. , the control signal to the next process cannot be given in advance, resulting in some difficulties in the control of the loose moisture regain process
(3) Other factors: due to factors such as tobacco leaf grade and origin, the moisture fluctuation of the material is relatively large, and when unpacking the basket, it will not be optimized according to the grade, origin and other factors. There are many factors and the randomness is large, and there is no rule to follow, which leads to the control of the process as empirical control, and the moisture of the material at the process outlet fluctuates greatly.
[0005] (1) Affecting product quality: resulting in large fluctuations in the moisture content of incoming materials in loose and moisture-recovery positions, causing chain transmission that is difficult to control the quality of the entire line, and causing a series of problems such as large moisture deviations in finished tobacco shreds
[0006] (2) Affecting the process control: The operating principle of the automatic control of loose moisture regain is to feed forward data from the moisture meter at the inlet of loose moisture regain, and calculate the instantaneous water addition amount through PID calculation. The amount of water added also changes accordingly, but the change rate of the amount of water added is slower than that of the water, which makes the water control unsatisfactory

Abstract

The invention discloses an intelligent control system for loose moisture regain equipment, which comprises a loose moisture regain inlet moisture prediction model, a loose moisture regain intelligent control model and a model docking unit. The invention realizes the precise intelligent control of the equipment, improves the uneven moisture content of loose and moisture-recovering outlet materials, improves the level of product average, provides stable materials for subsequent processes, and improves the quality of shredded tobacco. At the same time, the invention can reduce the number of on-site operators. Improve the difficulty of operation, transform the original experience control into system intelligent control, and reduce the labor intensity of personnel operation.

Description

technical field [0001] The invention relates to the tobacco industry, in particular to an intelligent control system for loose moisture regain equipment, which is suitable for the moisture regain treatment process of tobacco leaves, and is used to improve the moisture uniformity of materials and the level of product averaging. Background technique [0002] The loosening and regaining moisture process is the first moisture control process in the cigarette shred making process. The purpose of the process is to adjust the moisture of the material and increase the processing resistance of the material. The stability of the outlet moisture is directly related to the stability of the subsequent processing, and also affects the finished tobacco. fill value. The main reason affecting the moisture stability of the loose and regained outlet is the consistency of the moisture content of the incoming material. [0003] According to the investigation of the current production situation,...
