Leaf-threshing and stem-removing technology with leaf-threshing wind separation quality capable of being detected and controlled on line

Abstract

Disclosed is a leaf-threshing and stem-removing technology with leaf-threshing wind separation quality capable of being detected and controlled on line. A sampling detecting gathering conveyor belt is arranged on each level of leaf-threshing unit, a sampling device is respectively arranged on an outlet of a leaf-threshing device of each level of leaf-threshing unit and a discharge port of each wind separating device and sends samples to the sampling detecting gathering conveyor belt in the corresponding region, sampling devices used for sampling and sending samples to a prior level of sampling detecting gathering conveyor belt are also arranged at inlets of leaf-threshing devices of a second-level leaf-threshing unit and following-up leaf-threshing units, and a leaf and stem separating quality detecting device which can detect the samples on the sampling detecting gathering conveyor belts on line is arranged near each level of sampling detecting gathering conveyor belt. According to the leaf-threshing and stem-removing technology, intelligent control over the leaf-threshing devices in the section of the leaf and stem separating technology is realized, and leaf and stem separating quality is improved.

Description

Technical field [0001] The invention belongs to the technical field of tobacco threshing and destemming technology. Background technique [0002] Threshing and redrying is a process of separating the leaves and stems of the tobacco leaves after the initial curing, and then adjusting the moisture content to suit the requirements of storage and aging. Threshing and redrying is the "tether" that connects the original tobacco and cigarettes, and is a key process before the tobacco leaves are stored for aging. In the threshing and redrying process, the stalk separation process (that is, the threshing unit) is the only main process that affects the shape of the product. Its processing quality has a greater impact on the quality of silk, and the latter determines the quality of cigarettes (such as single The weight of the cigarette, the density of the cigarette, the amount of end thread, the short end rate and the stability of the rolling quality) are important factors. Therefore, how...

AI Technical Summary

Problems solved by technology

Therefore, the current threshing and destemming process has the following main defects: a) The detection results of the leaf-stem separation quality index cannot be used to timely adjust the working parameters of the threshing unit (such as the speed of the beating roller, the air distribution and air volume)

This method is time-consuming and labor-intensive, with poor real-time performance, and it is difficult to realize online detection, and the amount of detected information is very small, basically only one parameter is weight

c) It is difficult to meet the transformation of today's tobacco processing from result control to process control, from index control to parameter control, from manual control experience decision-making to automatic control scientific decision-making, and finally achieve the development goal of refined leaf threshing and re-baking
