Method for preparing reconstituted tobacco paper base made from tobacco stems

Abstract

The invention discloses a method for preparing reconstituted tobacco paper base made from tobacco stems, wherein the reconstituted tobacco paper base is prepared through taking the tobacco stems as a raw material and adopting a papermaking method and the preparing method comprises the steps of impregnation, defibrination, pulping, sheet making and drying of the tobacco stems. According to the invention, a technical scheme capable of optimizing the comprehensive property of the reconstituted tobacco paper base made from the tobacco stems is provided, which comprises treatment conditions of key processes of the impregnation, the defibrination, the pulping and the like; and a technical mean capable of improving the fiber morphology of the tobacco stems and the physical property of paper pulp is obtained. Showed by results, contents of water-soluble sugar, total plant alkaloid, chlorine and total nitrogen in the tobacco stems are decreased to varying degrees and the holocellulose content is relatively increased by 12.4% after the impregnation and extraction in the technical scheme provided by the invention are adopted; the fiber length of the obtained tobacco stem pulp is longest and the bulk of the finished paper is highest through selecting different types of refining plates and different defibrination gaps; and the tensile index, the tear index, the bulk, the air permeability and the burst index of a paper base product are appropriate and the good quality of reconstituted tobacco is guaranteed through combining the design of the beating degree of the tobacco stem pulp and the technical condition of the sheet making.

Description

technical field [0001] The invention belongs to the technical field of reconstituted tobacco production, and in particular relates to a method for preparing reconstituted tobacco leaves from tobacco stems. Background technique [0002] Reconstituted tobacco leaves are produced by using tobacco waste produced during tobacco processing through certain processing techniques. The reconstituted tobacco leaves produced by the papermaking method have the advantages of low density, large filling value, good mechanical properties, and low tar content, and have better effects in reducing harmful substances in the reconstituted tobacco leaves and improving various quality indicators of the reconstituted tobacco leaves. production technology. Therefore, the processing technology of the papermaking method plays a key role in the smoking quality and physical properties of reconstituted tobacco leaves. Tobacco stems account for about 25-30% of the weight of tobacco leaves. A large amou...

AI Technical Summary

Problems solved by technology

In the prior art including the above-mentioned documents, the research on the pulping performance of tobacco stems is mainly concentrated in the stage of impregnation and extraction, and the morphology of tobacco stem fibers and the paper-forming properties of tobacco stem fibers are affected during the preparation process of tobacco stems and reconstituted tobacco leaves. There are few studies on other key processes, and no related technical reports
