Tobacco material classifying device and method

Abstract

The invention provides a tobacco material classifying device and classifying method. The equipment comprises a winnowing box machine body, a tangential material discharging device and a classifying filtering mesh belt; the top of the winnowing box machine body is connected with the tangential material discharging device; the classifying filtering mesh belt is located on the upper portion of the winnowing box machine body, penetrates into one side of the winnowing box machine body and penetrates out of the other side of the winnowing box machine body; after the classifying filtering mesh belt penetrates out of the winnowing box machine body, a conveying device is arranged under the classifying filtering mesh belt. According to the tobacco material classifying device and method, materials move upwards through wind power, sundries fall into a sundry falling area due to the fact that the self gravity is larger than the wind power, cut rolled stems float and move upwards to a filter area, pass through the classifying filtering mesh belt and then collected and output, and flaky cut rolled stems are attached to the lower surface of the classifying filtering mesh belt, are taken out of the winnowing box machine body by the classifying filtering mesh belt, fall into the conveying device and then are discharged. Therefore, continuous, steady and uniform material classification is achieved, the defects that a traditional vibrating screen classifier is high in tobacco damage ratio, low in classification rate and the like are overcome, and the classification and usage requirements for different cut rolled stem forms in cigarette processing can be met.

Description

technical field [0001] The invention belongs to the technical field of cigarette manufacturing process equipment, and in particular relates to a method for grading shredded stems by air suction and filtration, and a shredded stem sorting machine for classifying shredded stems in filamentary shape, shredded stems in sheet shape, and stem labels. Background technique [0002] The annual output of tobacco leaves in my country is about 2.4 million tons, and about 600,000 tons of tobacco stems can be produced, of which about 400,000 tons can be effectively used. At present, cut stems are mostly used in middle and low-grade cigarettes, high-end cigarettes do not use cut stems or use a small amount, and the amount of cut stems in slim cigarettes that have developed rapidly in recent years is also very small. The use of cut stems in high-end cigarette products mainly has two problems: one is that the shape of cut stems is quite different from that of shredded leaves, expanded shreds...

AI Technical Summary

Problems solved by technology

The use of cut stems in high-end cigarette products mainly has two problems: one is that the shape of cut stems is quite different from that of shredded leaves, expanded shreds and other cut tobacco components, which is not conducive to the uniform mixing of cut stems and other cut tobacco components; Second, there are congenital defects in the sensory quality of cut stems, which will affect the sensory quality of cigarettes to a certain extent, and limit the use of cut stems in high-end cigarettes

This scheme cannot separate silky cut stems and flake cut stems. If the wind blown into the buoyancy sorting chamber is too large, the silky cut stems and flake cut stems will be blown up together and sucked out by the suction device; If the wind is too small, the flaky cut stems will fall on the sorting sieve together with the agglomerated and carbonized cut stems. Small and medium pieces of high-quality cut stems fall together on the receiving car. If the aperture is too small, the mixture of flake cut stems, heavier agglomerates and carbonized cut stems will be discharged from the waste port as waste, resulting in waste of cut stems; The mixture of shredded stems and shredded flakes needs to be separated again, and the separation efficiency is very low
