Tobacco stem sorting method suitable for different cigarettes

Abstract

The invention provides a tobacco stem sorting method suitable for different cigarettes. The method comprises the following steps: (1) preliminary screening of tobacco stems; (2) first screening: screening the tobacco stems obtained by the preliminary screening in the step (1) by adopting a vibrating screen screening device with a directional screen (1); (3) second screening: dividing the tobacco stems obtained in the step (2) into two strands, wherein the first strand is screened by a vibrating screen screening device with a directional screen (2) and the second strand is screened by a vibrating screen screening device with a directional screen (3); (4) third screening: screening the tobacco stems screened by the vibrating screen screening device with the directional screen (2) in the step(3) by using a vibrating screen screening device with a directional screen (3); and (5) respective collecting, packaging and marking and storing of the screened tobacco stems. According to the methodprovided by the invention, process route selection can be carried out according to actually required tobacco stem types. According to the method provided by the invention, the incoming quality of thetobacco stems is improved, so that the cut tobacco stem forming quality is improved, the cigarette quality is improved, and the blending of fine cut cigarette stems can be realized.

Description

technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for sorting tobacco stems suitable for different cigarettes. Background technique [0002] Tobacco stems account for about 25-30% of the leaf weight, and the stems after threshing are mainly from the main veins of tobacco leaves, with mixed lengths, shorts, thicks and thins. At this stage, the tobacco industry only divides tobacco stems into long stems and short stems for classification and collection according to a single indicator of length, that is, two specifications of long stems (L>20mm) and short stems (L<20mm). For details, see the 2001 edition of " YC / T146 Tobacco leaf threshing and redrying process specification "). It is a common practice in the industry to classify long stems and short stems by length. This method is relatively simple and easy to operate, and the process is simple. However, on the one hand, this method ignores the influence...

Problems solved by technology

However, practice has proved that under the condition of consistent production process and equipment, tobacco stems of different lengths and diameters have a significant impact on the quality of cut tobacco stems, which is a key factor affecting the quality of cut stems; at the same time, affected by the shape of cut stems, the existing Shredded stems are not yet available in slim cigarettes
