Tobacco stem soaking extracting processing method for tobacco stem reproducing technology

Abstract

The invention provides a tobacco stem soaking extracting processing method for a tobacco stem recombination reproducing technology, stem filament finished product yield can be improved, and tobacco stem using rate is effectively improved. The method comprises the following steps that tobacco stems are sent into tobacco stem expanding equipment for expanding processing, the tobacco stems after expanding are sent into soaking extracting equipment for soaking immediately, and after soaking extracting, the tobacco stems are sent into a squeezing-drying machine for solid-liquid separation. Through the tobacco stems processed with the method, all soluble matter in the tobacco stems can be basically extracted, the tobacco stems are processed into high-quality stem filaments in following processes, the method is used in middle-high-class cigarettes, and a new effective path is established.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing and manufacturing, and in particular relates to a production method for soaking and extracting tobacco stems used in the tobacco stem remanufacturing process. Background technique [0002] Tobacco stems account for about 25% of the tobacco leaves. At present, the processing technology and equipment for making tobacco stems into shredded stems are quite mature. The proportion of blended shredded stems in cigarettes varies according to the grade of cigarettes, but , Cut stems are mainly used in low-grade tobacco, which is mainly due to the characteristics of tobacco stems and the traditional processing technology. Relevant studies at home and abroad have shown that the physical characteristics and chemical components of tobacco stems are essentially different from those of tobacco leaves. The content of cellulose, hemicellulose, lignin, and pectin in tobacco stems is much higher than t...

Problems solved by technology

Experimental studies have shown that this method has a certain effect, but there are also problems: first, after the tobacco stems are shredded, their strength is weaker than that of the tobacco stems, and they are easy to break. Under the action of water and mechanical friction, part of the cut stems will be crushed. When the cut stems undergo solid-liquid separation, the extrusion process will cause the stems to displace each other, further resulting in crushing. The cohesive force makes it produce agglomeration, and when it is to be loosened, it will be broken again, which will seriously affect the yield of the product; the second, because the cut stems are soaked and extracted, the broken stems The reason is that the impurity content in the soaking liquid is high, which increases the difficulty and cost of sewage treatment
