Water adding control method and system for leaf silk super regain moisture

Abstract

The invention provides a water-adding control method and system for silk super-remoisture. The method includes: obtaining the moisture content of the incoming material of the silk, and calculating the average moisture content of the incoming material by taking the N times of sampling within a set time period as a sliding window . A sliding window of water content of incoming material for n samples including the current time is established, and the difference between the water content of incoming material at each time and the average water content of incoming material is calculated. If the difference values ​​corresponding to all moments in a sliding window are greater than or less than 0, it is judged that the moisture content of the incoming material has an overall increasing or decreasing trend, and the speed of the water pump of the damp conditioner is controlled within the sliding window. The outlet time corresponding to the first moment begins to decrease or increase, so as to adjust the water addition amount of the super moisture resurgence drum, so that the moisture content of the shredded silk outlet can be feed-forward controlled. The invention can improve the consistency of the outlet water content of each batch of shredded leaves, and improve the quality control ability of the production process.

Description

technical field [0001] The invention relates to the technical field of tobacco processing control, in particular to a water addition control method and system for super-moisturizing cut tobacco. Background technique [0002] In the shredding process of cigarettes, due to the high temperature expansion technology, the shredded tobacco is relatively large, and it is easy to cause the drying of the shredded shreds and it is difficult to obtain the shredded shredded leaves with a high yield rate. The super-moisturizing of the cut leaves is often carried out before the cut leaves are dried to add water to the cut tobacco to increase the moisture content of the cut leaves to 30% to 40%. Using a lower air temperature to make the leaf silk quickly dehydrate to achieve the purpose of drying. In the existing leaf silk super-moisturizing, the outlet moisture control of the leaf silk is mainly based on the detection and feedback of the outlet moisture content, and then the water additi...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a water-adding control method and system for the super re-moisture of shredded leaves, which solves the problem of hysteresis and inaccuracy in the adjustment of the outlet water content during the super-re-moisture of the existing shredded leaves, and can improve the outlet water content of each batch of shredded leaves Consistency, improve the quality control ability of the production process
