A method for improving the ash content of reconstituted tobacco leaves by papermaking process

Abstract

The invention discloses a method for improving the ash content of paper-making process reconstituted tobaccos. The method includes the steps that after tobacco raw materials are extracted, solid-liquid separation is carried out, tobacco liquid is partially refined, concentrated and charged and then is manufactured into coating liquid, pulping treatment is partially conducted on the tobacco solid part, so that tobacco slurry fibers are obtained, CaCO3 is added into the tobacco slurry fibers, and the CaCO3 is filled into cell cavities of the tobacco slurry fibers through pits of the tobacco slurry fibers; afterwards, the tobacco slurry fibers and additional fiber slurry are mixed according to the weight ratio of 4 to 1, and then paper manufacturing with pulp is carried out to manufacture reconstituted tobacco sheets; the coating liquid is made to coat the reconstituted tobacco sheets, so that the paper-making process reconstituted tobaccos are manufactured. According to the method, the technology that the CaCO3 is filled into the cell cavities of the tobacco slurry fibers is applied to the preparation technology of the paper-making process reconstituted tobaccos, any chemical agent such as a high-molecular polymer is not added, and the purposes that the ash content is improved and meanwhile the strength performance of the paper-making process reconstituted tobacco sheets is improved can be achieved.

Description

technical field [0001] The invention relates to the preparation of reconstituted tobacco leaves by papermaking method, in particular to a method for increasing the ash content of reconstituted tobacco leaves by papermaking method. Background technique [0002] The production of reconstituted tobacco leaves by papermaking means that the tobacco raw materials such as tobacco stems, tobacco dust and some low-grade tobacco leaves produced in the process of threshing and redrying and cigarette production are first extracted with a solvent (usually water), and then separated from solid and liquid. Part of it is processed into a substrate (base paper) according to the papermaking method, and the liquid part is refined and purified, concentrated and flavored to prepare a coating liquid, and then the coating liquid is applied to the substrate by double-roller coating, etc., and heated by hot air. After drying and slicing, it is finally made into a sheet-like substance close to natura...

Problems solved by technology

Although the above invention patents have improved or optimized the cell wall filling process and retention technology of the filler, they often discuss and study a single influencing factor without systematic research, and often need to add a small amount of water-soluble polymer. Polymers (the use of high molecular weight polymers in reconstituted tobacco leaves is strictly regulated)

[0007] At present, CaCO has not been adopted at home and abroad. 3 Related reports on increasing the ash content of reconstituted tobacco leaves by papermaking process by filling the cell lumen of tobacco pulp fibers
