Centralized collection and classified treatment system and method for crumbled tobacco of leaf laying process in threshing and redrying technology

Abstract

The invention discloses a centralized collection and classified treatment system and method for crumbled tobacco of the leaf laying process in a threshing and redrying technology. The system comprises leaf laying tables, a crumbled tobacco collecting and separating unit, a slow-speed picking belt, a bundle breaking conveying belt and an air-conveying pipeline system; the leaf laying tables are arranged on multiple leaf laying stations respectively, and one end of each leaf laying table is provided with multiple crumbled tobacco collecting holes; the crumbled tobacco collecting and separating unit comprises a crumbled tobacco collecting and conveying belt, a vibrating separation device, the slow-speed picking belt and an electromagnetic three-stage vibrating screen. The crumbled tobacco produced in the leaf laying process is collected in a centralized mode through the crumbled tobacco collecting holes and conveyed to the vibrating separation device for separation, various impurities form clusters and the crumbled tobacco to be discharged, and by means of picking and impurity removing, the crumbled tobacco enters the three-stage vibrating screen for stage treatment. According to the centralized collection and classified treatment system and method for the crumbled tobacco of the leaf laying process in the threshing and redrying technology, by means of centralized collection and treatment of the crumbled tobacco of the leaf laying process and combination of the vibrating separation device and artificial picking, the content of the impurities in a product is reduced, the purity of tobacco leaves is improved, the technological purpose of removing the impurities for purifying is achieved, and resource waste is reduced.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf threshing and redrying, in particular to a system and method for centralized collection and classification of shredded tobacco in the leaf laying process in leaf threshing and redrying. Background technique [0002] The existing pretreatment process of threshing and re-curing tobacco leaves mainly includes the processes of tobacco leaf sorting, tobacco leaf loosening, precise proportioning, leaf laying and unhacking, temperature increase and humidification, purification and impurity removal, and temporary storage of raw materials. With the needs of the brand development of industrial enterprises, it has become one of the key factors in the brand competition of various industrial enterprises to pay attention to the quality control of the raw material guarantee link. The impurity removal and purification in the process of leaf threshing and redrying ensures the stability of cigarette quality. I...
