Problems solved by technology

Among the common heat-not-burn tobacco products in the market, some use the thick slurry method sheet, which has the disadvantages of strong surface adhesion, less tobacco aroma, mainly flavoring outside the smoke, and deviation in processing performance; some use the Dry-process flakes, the R&D platform has low output of small products, does not have the capacity for large-scale production, and the smoke volume after being made into cigarettes is relatively small

Abstract

A method for heat non-combustible tobacco sheet and coating liquid thereof by pap making method includes such steps as concentrating liquid of tobacco, smoke agent, viscosity reduce agent and combustion promoter, concentrating liquid of tobacco 20-90 g and smoke agent 10-80 g per 100 g of concentrated liquid of tobacco and smoke agent, coating liquid of tobacco 20-90 g and smoke agent 10-80 g per100 g of concentrated liquid of tobacco and smoke agent, coating liquid of tobacco 10-80 g per 100 g of concentrated liquid of tobacco and smoke agent, coating liquid of tobacco 10-80 g per 100 g of non-combustible liquid, coating liquid of tobacco 10-80 g per 100 g of non-combustible liquid, coating liquid of non-combustible liquid, coating liquid of non-combustible liquid and coating liquid of non-combustible tobacco. 1 to 15 g of viscosity reduce and 1 to 8 g of combustion promoter per 100 g of tobacco concentrate and smoke agent. By means of the coating liquid of the invention, the heatednon-combustible tobacco sheet obtained by the coating method endows the papermaking tobacco sheet with a high proportion of glycerol, and has low surface adhesion and friction.

Description

technical field [0001] The invention belongs to the field of novel heat-not-burn tobacco products, and in particular relates to a paper-making heat-not-burn tobacco sheet and its coating solution, coating method and preparation method. Background technique [0002] The world cigarette market is facing the third revolution after the birth of the cigarette machine and the advent of the filter tip. As a new type of tobacco product, the new heat-not-burn cigarette is gradually becoming the product pursued by the new generation of smokers, and its market share is gradually increasing. Improvement, rapid development momentum, significant reduction in harmful chemical components and biological toxicity of smoke, and easier acceptance by younger smokers. Therefore, the research on new tobacco products and their heating devices has gradually become the key work of various tobacco industries, among which the research on tobacco products is the most important. [0003] Papermaking rec...
