Threshing wind separation set and method for processing tobacco leaves by utilizing five-threshing and eighteen-separation process

Abstract

The invention provides a threshing wind separation set and method for processing tobacco leaves by utilizing a five-threshing and eighteen-separation process, which can be used for classification and mixing processing of leaf-base, non-leaf-base and full-leaf module tobacco leaves. A whole production line is compact and equipment investment is saved, wherein five grades of threshing sets and eighteen sets of wind separation devices are alternately arrayed in sequence to form linear arrangement; first-grade threshing wind separation is realized by 6 threshing sets and 7 threshing sets, and 8 wind separation device sets; second-grade threshing wind separation is realized by 3 threshing sets and 4 wind separation device sets; three-grade threshing wind separation is realized by 2 threshing sets and 3 wind separation device sets; four-grade threshing wind separation is realized by 2 threshing sets and 2 wind separation device sets; five-grade threshing wind separation is realized by 2 threshing sets and 1 wind separation device set; the first and second wind separation devices and the three grades of threshing wind separation can be selectively used; and selection channels are configured by adopting a bidirectional feeder, a proportional distribution feeder, a double-channel switching device and a material distributor. The threshing wind separation set also has the flexible and fine machining characteristics and realizes intelligent, efficient and low-cutting threshing wind separation.

Description

technical field [0001] The invention relates to the field of tobacco processing, and is suitable for the tobacco leaf threshing and redrying process. Specifically, in the threshing and redrying process, the tobacco leaves are torn, air-selected and transported, so as to realize the separation of tobacco slices and tobacco stems, and meet the requirements for cutting and classifying different tobacco leaves. Advanced processing technology realizes intelligence, high efficiency, and low damage and threshing wind. Background technique [0002] In the tobacco processing industry, although the rebaking process of tobacco leaves belongs to the primary processing, it is the most basic process and an indispensable and important link in the production of cigarette industry, and its importance is self-evident. Tearing, sorting and transporting the tobacco leaves, finally realizing the separation of the tobacco sheets and clean tobacco stems, and controlling the shape and size of the o...

Problems solved by technology

The threshing air classification of tobacco leaves is a cumbersome physical processing process. For different grades of tobacco leaves, the relevant threshing indicators are different, such as the rate of large and medium sheets, the rate of leaf stalks, the rate of stems and leaves, the rate of long stems, The crushing rate, etc., also use the same number of levels of threshing, how many levels of wind, and the resulting quality indicators are not the same. No matter what the specifications are, it also needs to be scientifically designed according to factors such as processing capacity, tobacco leaf properties, and module attributes; a piece of tobacco leaf is cut into leaf-based and non-leaf-based modules to form leaf-based modules and non-leaf-based modules. The roasting process requires classification and combination processing of leaf-based modules, non-leaf-based modules and full-leaf module tobacco leaves. Due to different module combinations, the processing technology requirements are not the same. For the leaf-based module, it is necessary to design a leaf-threshing air sub-unit of "three-level threshing and eight-level air classification" (referred to as "three-level 8-point"). For the completion of processing non-leaf-based module and full-leaf module tobacco leaves, it needs to be redesigned "Four-level threshing and fifteen-level wind points" (referred to as "four threshing fifteen points") defoliation sub-units, such a traditional scheme has problems such as large equipment investment, large space occupation, and high energy consumption, and according to process requirements The quality of the obtained cigarettes and clean stems is not up to the optimal control effect
