Process for accurately controlling stability of water content after shredding

Abstract

The invention relates to a process for accurately controlling the stability of the water content after shredding. The process comprises the steps that a set amount of water is added into leaves; a setamount of feed liquid is added into the leaves with the water added through a feeding procedure; the leaves with the feed liquid added are stored under the conventional leaf storage condition; the current instant water content of the leaves subjected to primary leaf storage is detected, the difference value between the current instant water content and the set water content is calculated througha control system, and the amount of water corresponding to the difference value added into the leaves through a water adding system is controlled; and secondary leaf storage is conducted, and the leaves with the water added again are stored under the conventional leaf storage condition and then enter the subsequent procedure. According to the process, the volatilization amount of the feed liquid is far smaller than that of feed liquid in an existing production process, the difference value between the water content obtained after primary material storage and the set water content is obtained by detecting the water content, secondary storage is conducted after the amount of water for supplementing the difference value is controlled, the stability of the water content of shredded tobacco isguaranteed, the feeding uniformity is improved, and the quality of the shredded tobacco is improved.

Description

technical field [0001] The invention belongs to the technical field of shredded cigarettes, in particular to a process for precisely controlling the stability of moisture content after shredded. Background technique [0002] The tobacco bales after threshing are loosened into tobacco sheets. Before the cutting process, the tobacco sheets need to be treated accordingly, especially the parameters such as the control of moisture content. In order to ensure that the moisture content of the shredded leaves remains relatively Stability (standard deviation shrinks, CPK reaches above 1.33, etc.). As shown in the picture, the current process is to control the amount of water added according to the difference in the moisture content of the leaves before the first loosening and resurgence, that is, to control the water addition in steps, when the water content of the loose leaves before the first loosening and resurgence When the rate is relatively high, increase the amount of water a...
