Method for processing tobacco stems into shredded stems

Abstract

The invention discloses a method for manufacturing stem shreds by processing tobacco stems. The method includes the steps of stem and leaf separating, tobacco stem screening, tobacco stem warming and humidifying, stem pressing, stem roasting, tobacco stem storing, tobacco stem dampening, tobacco stem formula mixing, secondary tobacco stem warming and humidifying, second stem pressing, stem shred cutting, stem shred adding, stem shred warming and humidifying, stem shred drying, stem shred winnowing, perfuming and the like. A whole set of complete new stem shred processing method from leaf hitting tobacco stem re-roasting processing to stem shred manufacturing from the tobacco stems is formed. According to the method, the stem shred production environment is improved; the production cost is reduced; the stem shred quality is improved. The method is easy and convenient, and strong in maneuverability; and large-scale production and application can be conveniently achieved.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to a method for processing tobacco stems and making them into shredded stems. Background technique [0002] Tobacco stems are a component of tobacco leaves, and the threshed tobacco stems account for 25-30% of the total weight of tobacco leaves. At present, cigarette factories generally make tobacco stems into shredded stems and use them as cigarette fillers. Tobacco stems are strip-shaped and compact in structure, and the existing cut stem processing methods are relatively complicated, and the processing process has little effect on improving the internal quality of cut stems. [0003] The processing technology of cut stems in the 2003 edition of "Cigarette Technology Standards", as well as the production technology of tobacco stems and cut stems that are widely used in threshing and redrying factories and cigarette factories today are mainly: After the stems and lea...

AI Technical Summary

Problems solved by technology

This method, first of all, does not fully consider the influence of the broken stems and stem head stems on the quality of cut stems in the process of threshing and re-roasting, and secondly, it does not make full use of the characteristics of the soft tissue of the new stems to process the tobacco stems , so that the tobacco stems are loosened, which is beneficial to further silk making; and during the process of rebaking and roasting the tobacco stems, the preliminary transformation of the undesirable chemical components inside the tobacco stems improves the quality of the tobacco stems; the traditional process method does not loosen the tobacco stems during rebaking Tobacco stems fed from the warehouse are dry and hard, and the tobacco stems can only be rehydrated by washing, moistening the stems, and storing the stems for a long time before performing treatments such as pressing and cutting the stems. Hot water causes a lot of waste of water resources and heating electric energy, and the surface water brought out by the washed tobacco stems volatilizes, deposits and drips in the tobacco stem conveyor belt and stem storage cabinet, affecting the cleanliness of the production environment, and the washed stems produce A large amount of sewage enters the urban sewage pipe network, increasing the pressure on urban sewage treatment

Third, due to the tight tissue of the tobacco stems, the tobacco stems cannot fully absorb water in the short-term washing process when washing the stems, and it takes a long time to store the stems to allow the water to penetrate into the interior of the tobacco stems, increasing the online stability of the cut stems. Production time; Fourth, the traditional method of shredded tobacco stems will generate a lot of dust during the feeding process of loose bales of tobacco stems, which will have a great impact on the production environment;

[0004] At present, in the prior art, there is also a method of pressing stems by threshing leaves and re-roasting raw stems, see Chinese patent CN102599640, but this method is mainly based on adding enzyme treatment after pressing stems to improve the quality of shredded stems, and directly combines red-roasting and making The method of wire connection does not fully consider the problem that a large amount of tobacco stems after threshing and redrying cannot be used and digested in time in the cigarette factory, and the problem that storage needs to be carried out after roasting

Second, there is no proposed method of using threshing and re-roasted tobacco stems to increase temperature and humidity and then quickly dry to expand the tobacco stems; third, there is no proposed stem-making process for tobacco stems with low moisture content after storage of tobacco stems

[0005] Generally speaking, although there are many researches on the processing technology of cut stems at this stage, there is still no optimal treatment plan for cut stems that comprehensively considers the whole process from threshing and re-roasting to making cut stems
