A kind of threshing and redrying processing method of tobacco leaf raw material

Abstract

The invention provides a threshing and re-drying processing method of high-grade tobacco leaf raw materials. According to the method, tobacco leaves on the upper portion and in the middle serve as the raw materials and divided into multiple segments according the lengths of the leaves, and the total weight and the nicotine content of each segment of tobacco leaf of each portion are determined; before feeding and threshing, multiple threshing combined formulas are formed through matching according to the total feeding amount and the content of chemical components, wherein the addition amount of the tobacco leaves in the middle portion in each formula is not smaller than 30%, and the same segments of tobacco leaves of the same portion are added into the same formula; the content of the tobacco leaves on the upper portion and the nicotine content in each formula are calculated, a threshing and re-drying formula meeting feeding requirements is determined for feeding, and then threshing and re-drying start according to an existing threshing and re-drying technology to obtain the combined high-grade tobacco leaf raw materials. The method guarantees uniformity and stability of the tobacco leaves obtained after threshing and re-drying, and can provide the good-quality and uniform tobacco leaf raw materials for high-end brand cigarettes.

Description

technical field [0001] The invention belongs to the field of threshing and redrying of tobacco leaves, in particular to a processing method for threshing and redrying of tobacco leaf raw materials. Background technique [0002] Tobacco leaf resources are an important basis for the survival and development of cigarette industry enterprises, an important resource that has a restrictive effect on the development of cigarette products, and an important foundation for shaping the differentiation of cigarette brands. The stability of cigarette product quality largely depends on the stability of tobacco leaf raw materials sex. Without the guarantee of high-quality tobacco leaf resources, the development of cigarette brands is like a "castle in the air", lacking an important foundation for survival and development; without the guarantee of characteristic high-quality tobacco leaf resources, how can we talk about the differentiation of cigarette brands and the differences of cigarett...

AI Technical Summary

Problems solved by technology

[0004] In the production and manufacture of Chinese-style cigarettes, cigarette companies will also combine, proportion and optimize the internal quality similarities of different regions, varieties and grades of raw tobacco according to the characteristics of their own brand formula and process mode, and determine the appropriate tobacco leaf formula ratio, and then entrust threshing and redrying enterprises to carry out specific processing operations; due to the characteristics of many grades and small batches of domestic tobacco leaves, multi-grade formula threshing has gradually become the main method of tobacco leaf processing, which will inevitably lead to the same batch of tobacco leaf raw materials as a whole. uneven mass distribution

The physical and chemical indicators of raw tobacco have a great relationship with the internal evaluation and smoking quality of finished cigarettes. The source of stability control of cigarette quality is mainly tobacco leaf raw materials, especially some well-known brand cigarettes, which pay more attention to the evaluation and smoking effect of cigarettes. However, the uniformity and stability of the quality of threshing and redrying still fail to meet the needs of cigarette industry enterprises for the quality of tobacco raw materials, let alone meet the needs of high-end cigarettes for the quality of tobacco leaf raw materials
