Problems solved by technology

[0004] To sum up, papermaking reconstituted tobacco has the effects of "turning waste into treasure" and "reducing tar and harm", and plays an important role in the development of Chinese-style cigarettes. However, most smokers in China currently have a deep-rooted understanding of the color of tobacco leaves, na...

Abstract

The invention relates to the technical field of production of papermaking-reconstituted tobacco, in particular to a method for regulating the color of the surface of the papermaking-reconstituted tobacco. The method comprises the steps of (1) adding pigment and brightness additives to a tobacco concentrated solution according to color indexes expected to be presented by the reconstituted tobacco after pigment regulation; (2) coating base sheets of the reconstituted tobacco with the tobacco concentrated solution obtained from the step (1); (3) processing the base sheets obtained from the step (2) in an oven and obtaining finished products of the reconstituted tobacco after water balancing is conducted under constant temperature and humidity. According to the method for regulating the color of the surface of the papermaking-reconstituted tobacco, the probability that production requirements can not be met due to unreasonable adding of pigment is reduced, and a systematic and unprecedented breakthrough is realized in regulation of the color of the surface of the reconstituted tobacco.

Description

technical field [0001] The invention relates to the technical field of production of reconstituted tobacco leaves by papermaking methods, in particular to a method for regulating the surface color of reconstituted tobacco leaves by papermaking methods. Background technique [0002] Paper-process reconstituted tobacco (Paper-process reconstituted tobacco), also known as tobacco sheet, is a kind of "artificial tobacco leaf" made by processing tobacco by-products and waste materials using modern extraction and separation technology and improved papermaking technology, also known as papermaking. The reconstituted tobacco leaf is mainly made of tobacco pulp made from waste materials in tobacco processing such as tobacco stems, shredded tobacco and tobacco powder, mixed with a certain amount of wood pulp and fillers, and then copied into a substrate by a paper machine and then dipped and coated. have to. [0003] Paper-making reconstituted tobacco has become an important part of ...
