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 adjust the working parameters of the threshing unit (such as the rotating speed of the beating roller, the air distribution and air volume) in a timely manner.
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

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] Leaf threshing and redrying is the process of separating the leaves and stems of the tobacco leaves after the initial roasting, and then adjusting the moisture content to meet the requirements of storage and aging. Threshing and redrying is the "link" connecting raw tobacco and cigarettes, and is a key process before tobacco leaves are put into storage for aging. In the leaf threshing and redrying process, the leaf stem separation process section (i.e. the leaf threshing unit) is the only main process that affects the product shape, and its processing quality has a greater impact on the silk quality, and the latter determines the quality of cigarettes (such as single important factors such as cigarette weight, cigarette density, tip droop volume, short rate and rolling quality stability). Therefore, how to improve and stabilize t...
