Description
Technical Field
The application relates to a wet-process powder forming preparation method containing agilawood tobacco auxiliary materials and a tobacco product, and belongs to the field of tobacco sheet preparation.
Background
The production process technology of the tobacco sheet (also called reconstituted tobacco) is developed for more than half a century and mainly goes through three stages of a rolling method, a thick pulp method and a paper-making method, and the paper-making method (wet method) production process technology is dominant in the market of China due to strong plasticity and good filling property.
Paper-making (wet) tobacco sheet production main raw materials are derived from tobacco by-products such as: tobacco fragments, tobacco dust, tobacco stems, ash, and the like. At present, the tobacco sheet is an indispensable part in Chinese style cigarette leaf formula, and the tobacco sheet has the characteristics of reducing harm and tar, stabilizing product quality and highlighting cigarette style when being applied to the cigarette leaf formula.
The cigarette paper of the cigarette and the inner sleeve of the machine-made cigar are used as the necessary cigarette auxiliary materials of the cigarette and the machine-made cigar and can be used for wrapping and forming cigarette tobacco shreds (the cigar cores of the machine-made cigar). The cigarette paper and the inner cigar sleeve of the machine-made cigar sold in the market of China at present are processed by different types and proportions of wood pulp and raw materials such as hemp pulp, straw pulp and the like.
With the increasing demands of tobacco consumers on the safety, functionality and individuation of cigarettes and mechanism cigars, the traditional tobacco sheets take tobacco byproducts as raw materials, are applied to cigarette leaf group formulas, mainly feature the herbal fragrance of the cigarettes, and have limited effect of highlighting other fragrance notes; the cigarette paper and the machine-made cigar inner sheath which are produced by only taking wood pulp, hemp pulp, straw pulp and the like as raw materials generally have the problem of wood miscellaneous gas or other miscellaneous gas, and are easy to generate negative effects on sensory quality.
Aquilaria sinensis is an Aquilaria tree, and is mainly distributed in Guangdong and Hainan. Is listed as the top-class fragrance since ancient times and is always used as the top-grade spice.
In recent years, innovative research on tobacco materials by industrial workers is not interrupted, but contents of 'agilawood functional type' tobacco materials prepared by a wet papermaking process based on agilawood stem processing products (shovelling and snagging), plant fibers and tobacco raw materials as main body leaf group formulas are not reported.
