Cut stem preparation method capable of improving cigarette ash whiteness

Abstract

The invention discloses a cut stem preparation method capable of improving cigarette ash whiteness. The cut stem preparation method comprises the following steps: (1) carrying out elution treatment onraw material tobacco stems; (2) repairing the eluted tobacco stems by adopting glycerol so as to recover the processing resistance of the tobacco stems; and (3) removing residual glycerol on the tobacco stems, and shredding the tobacco stems to obtain the tobacco stem shreds. After the stem shreds for the cigarettes are added into the cigarettes for use, the ash whiteness of the cigarettes can beobviously improved by 15-30 units, the ash coagulation index is reduced by 1-2 units, the sensory quality of the cigarettes is slightly changed, potential safety hazards are avoided, and compared with a common process for improving the ash whiteness of the cigarettes through stem shred treatment (the breakage rate is about 10-20%), according to the method, the crushing rate can be controlled within 2-3%, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of cigarettes, in particular to a method for preparing shredded stems which can improve the whiteness of cigarette ashes. Background technique [0002] In recent years, with the improvement of consumers' pursuit of cigarette quality, designers have begun to optimize some cigarette details, and the whiteness of cigarette ash is one of them. Generally speaking, the whiteness of soot can be roughly divided into two types, one is the whiteness of the ash column, that is, the whiteness of the outer surface of the columnar ash that appears after the cigarette is burned; the other is the whiteness of the tobacco ash, that is, the whiteness of the inner tobacco after burning , the whiteness of the burning ash of shredded tobacco after peeling off the ashes of the cigarette paper. The ash column whiteness of cigarettes is mainly related to the burning properties of cigarette paper and its matching with shredded toba...

AI Technical Summary

Problems solved by technology

[0003] Although adding some functional additives to cut tobacco can improve the whiteness of cut tobacco ash, it often brings some unpredictable safety hazards, so it is rarely used

[0004] In addition, due to the dense structure of cut stems, it is easy to burst when burned, which affects the ash property of cigarette packs, so it is generally not used directly in cut tobacco formulations

Although expanded shredded stems can greatly reduce the bursting situation, due to the high content of non-flammable components such as pectin, the burning ash is generally black, resulting in the blackening of cigarette ash and affecting the consumption experience of consumers.

However, in the prior art, the conventional shredded stems (i.e. expanded shredded stems) that have been formed are processed. Although the process is relatively simple, it will cause a large amount of crushing during the processing. The current normal elution process crushing rate It will reach about 10-20%. For large-scale industrial production, the cost loss is relatively large
