Problems solved by technology

Although the existing tobacco stem pulping process dissociates and disperses the fibers to a certain extent, the obtained tobacco stem pulp has high organic matter content, low fiber content, low fiber strength, and heavy impurities. The cloth has little absorption
At the same time, the existing tobacco stem pulping process cannot completely remove the macromolecular organic matter on the tobacco stem fiber bundles, and the degree of fibrosis of the tobacco stem fibers is also relatively low. In the subsequent pulping and papermaking processes, a large amount of high-concentration Organic wastewater and impact on reconstituted tobacco leaf base and products

Abstract

The invention relates to a novel flexible tobacco stem pulping process, which belongs to the technical field of tobacco stem pulping. In the invention, the tobacco stems are subjected to enzymatic hydrolysis treatment under weakly acidic and weakly alkaline conditions respectively; Heat steaming and steam explosion pre-defibration (coarse defibration); steam explosion the coarse defibrated tobacco stems treated above, and then undergo two-stage high-consistency disc refining and two-stage low-consistency refining to obtain significantly improved quality Tobacco stem fiber pulp; finally, the obtained tobacco stem pulp is blended with tobacco leaf pulp, wood pulp, calcium carbonate filler, etc., and after conventional papermaking, coating and drying processes, high-quality reconstituted tobacco leaf products are obtained. The present invention combines tobacco stem bio-enzyme treatment technology, steam explosion technology, etc. into tobacco stem pulping, forming a brand-new flexible tobacco stem pulping process, dual regulation technology of tobacco stem structure and main component, and develops High-quality, low-harm recombinant tobacco.

Description

technical field [0001] The invention belongs to the technical field of tobacco stem pulping, and in particular relates to a novel flexible tobacco stem pulping process. Background technique [0002] Reconstituted tobacco leaf (hereinafter referred to as RCT), referred to as tobacco sheet, also known as reconstituted tobacco (Reconstituted Tobacco), is a kind of tobacco stem (the main tendon of tobacco leaf), tobacco powder, fine fragments, etc. Artificially recombined and reconstituted new tobacco leaves produced from tobacco waste. RCT has been widely used in international and domestic cigarette production, and it has also been widely used in heat-not-burn cigarettes, which have developed rapidly in recent years. The use of RCT in cigarettes can effectively reduce cigarette tar and a variety of harmful components in smoke, improve the quality of cigarette smoking, and reduce the cost of cigarette (leaf group) formulations. Papermaking reconstituted tobacco leaves are usua...
