Method for online detecting and evaluating online cut tobacco mixing uniformity of cigarette

Abstract

The invention belongs to the technical field of tobacco processing, and concretely relates to a method online for detecting and evaluating the online cut tobacco mixing uniformity of cigarette. A principle that the sugar / nicotine ratio of online cut tobacco of the cigarette can well reflect the intrinsic quality of the tobacco is used to establish a method for evaluating the online uniformity by using the difference of the online sugar / nicotine ratio of the cut tobacco. The method mainly comprises the following steps: preparing a model sample; determining the respective content of total plant alkaloids and total sugars in the sample by using a continuous flow technology; establishing a model for predicating the content of the total plant alkaloids (total sugars) in the cut tobacco sample; and predicating the content of the total plant alkaloids (total sugars) after the uniform mixing of the online cut tobacco according to the model, and evaluating the mixing uniformity of the cut tobacco according to the predicated content. The method can accurately realize online and real-time monitoring and evaluation of the uniformity of the mixed cut tobacco in order to lay a foundation for the stability of the quality of the cigarette; and the method can provide reference for the improvement of relevant processes and the fine control of cigarette production, so the method has good practical values and promotion and application meaning.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing, and in particular relates to a patent application for a method for detecting and evaluating the uniformity of mixed shreds in online cigarette shredding. Background technique [0002] The refined production of cigarettes is the focus of research in the tobacco industry at present, and the research on the uniformity of mixed shreds is one of the concrete manifestations of the refined production of cigarettes. Cigarette raw material leaves include not only shredded leaves, but also cut stems and expanded cuts. The mixing uniformity of cut tobacco and cut stems plays an important role in supporting the stability of cigarette product quality. The blending uniformity of shredded tobacco raw material will directly affect the stability of the internal quality of cigarette products, that is to say: only by ensuring the uniformity of shredded tobacco blending can the smoking quality of each cig...

AI Technical Summary

Problems solved by technology

But in general, because the tobacco production enterprises in the existing technology mainly monitor and control the raw material ratio precision, but there is still a lack of clear requirements for the level of blending and the uniformity of online blending, and the existing research is still in the category of There is a certain distance between basic theoretical research and actual production and application conditions, so there is still a lack of better detection and evaluation methods for online mixed yarn uniformity in actual production
