Method for reconstituted tobacco leaves loaded with tobacco fragments manufactured by dry-laid papermaking technology

Abstract

The present invention provides a method for regenerating tobacco leaves by loaded tobacco fragments manufactured by a dry papermaking technology, and belongs to the field of a tobacco product machining method. The method comprises the following two steps: step 1, sorting the tobacco fragments and adding the tobacco fragments in a substrate forming process, conveying fibers into a first forming device (1) after plant fibers are deliberated into single fiber shapes, and forming a fiber layer (7) by using an airflow net forming method; and step 2, spraying paste prepared from the tobacco fragments, tobacco powder and an adhesive on the formed substrate, i.e. spraying the paste made of the tobacco fragments, the tobacco powder and the adhesive on one surface of the substrate, drying, then spraying the paste made of the tobacco fragments, the tobacco powder and the adhesive on the other surface of the substrate and drying to obtain the tobacco leaves regenerated by the loaded tobacco fragments manufactured by the dry papermaking technology. By virtue of the method, not only can procedures be reduced, but also powder-falling and dust-raising phenomena caused by excessive tobacco powder are reduced, the use amount of the adhesive is also reduced and the smoking quality is improved.

Description

technical field [0001] The invention belongs to the field of tobacco product processing methods, and in particular relates to a new process of reconstituted tobacco loaded with tobacco fragments manufactured by dry-laid papermaking technology. Background technique [0002] Reconstituted tobacco leaves, also known as tobacco flakes, reconstituted tobacco leaves or homogeneous tobacco leaves, are mainly composed of tobacco chips, shreds, tobacco stems or low-grade tobacco leaves, plus some plant fibers, adhesives, flavors and fragrances and other additives. As a raw material of cigarette products, reconstituted tobacco leaves have been widely used in cigarette products because of their low cost and good filling properties. After adding, they can reduce the tar content and some harmful substances in cigarettes. [0003] The reconstituted tobacco leaf began in the 1950s. At the beginning, the thick pulp method and the rolling method were mainly used. Due to the backward technolo...

AI Technical Summary

Problems solved by technology

However, the reconstituted tobacco leaves produced by the existing dry-process papermaking technology are finally attached to the surface of the substrate as a dried product composed of tobacco powder and adhesive. When the slices are cut into shreds, the edge end face is very easy to lose powder, resulting in a high powder loss rate and severe dust, which affects product quality and production environment.

Due to the use of a large amount of adhesives to fix the tobacco powder, the smoking quality and quality of the reconstituted tobacco leaves will also be affected to a certain extent due to the excessive use of adhesives
