Tobacco stem treatment method for improving papermaking method remanufactured tobacco leaf quality

Abstract

The invention discloses a method for treating tobacco stems for improving the quality of reconstituted tobacco leaves by a papermaking method, which comprises the following steps: adding the pretreated tobacco stems together with water into a stirring extraction tank, extracting at high temperature, and squeezing dry to obtain tobacco stems A; Tobacco stem A is sent to the thread rolling machine for thread rolling to obtain tobacco stem B; Tobacco stem B and water are added to the stirring extraction tank, after high temperature extraction, squeezed dry to obtain Tobacco stem C; The composite solvent is added to Tobacco stem C is stirred and soaked at high temperature to obtain a mixed solution D; the mixed solution D is added to a refiner, and the slurry E is obtained through refining treatment; the slurry E is processed by sheeting and coating, and then dried, Cut and serve. Compared with the traditional method, the extraction rate of the active components of the tobacco stems of the present invention is high, the beating degree of the tobacco stem pulp is improved, the energy consumption of the subsequent beating is reduced, the fiber quality of the tobacco stem pulp is improved, and the quality of the reconstituted tobacco leaves by the papermaking method is improved. .

Description

technical field [0001] The invention relates to the technical field of production of reconstituted tobacco leaves by papermaking methods, in particular to a tobacco stem treatment method for improving the quality of reconstituted tobacco leaves by papermaking methods. Background technique [0002] Paper-making reconstituted tobacco leaves are sheet or shred reconstituted tobacco that is reprocessed and combined with tobacco stems and tobacco powder as raw materials with the help of papermaking technology and equipment. Papermaking reconstituted tobacco has incomparable advantages over natural tobacco in terms of reducing tar and harm, and regulating the chemical components of cigarettes. It has become the focus of research and attention in the tobacco industry at home and abroad, and has developed rapidly in recent years. As cell wall substances, lignin and pectin are ubiquitous in tobacco raw materials, and tobacco stems contain about 6% lignin and 15% pectin respectively. ...

AI Technical Summary

Problems solved by technology

Existing studies have used biological enzyme treatment or urea alkali and weak alkali chemical methods to treat tobacco stems before or during the extraction of tobacco stems, but these methods have their disadvantages. The removal effect of biological enzyme treatment on lignin and pectin Weaker, and the processing cost is high; using chemical methods to treat the tobacco stems before extraction will inevitably lead to the loss of useful substances in tobacco; using chemical methods during the extraction process, lignin fragments and pectin fragments still exist in the extract after treatment Among them, the improvement of the quality of reconstituted tobacco leaves will be discounted, and chemicals entering the extraction solution will have a negative impact on the quality of reconstituted tobacco leaves
