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, and belongs to the technical field of tobacco stem pulping. The novel flexible tobacco stem pulping process comprises the following steps: firstly, respectively carrying out enzymolysis treatment on tobacco stems under weakly acidic and weakly alkaline conditions; then subjecting the treated tobacco stems to thermal steaming and steam explosion pre-defibration (coarse defibration); performing steam explosion on the treated coarse defibrated tobacco stems, and performing two-stage high-concentration disc mill defibrination and two-stage low-concentration defibrination treatment to obtain tobacco stem fiber pulp of which the quality is obviously improved; and finally, blending the obtained tobacco stem pulp with tobacco leaf pulp, wood pulp, calcium carbonate filler and the like, and carrying out conventional processes of paper making, coating, drying and the like to obtain a high-quality reconstituted tobacco product. A tobacco stem bio-enzyme treatment technology, a steam explosion technology and the like are jointly applied to tobacco stem pulping, a brand new flexible tobacco stem pulping technology is formed, and high-quality and low-harm recombined tobacco is developed through a tobacco stem structure and main component dual-regulation technology.

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...
