  • the original smoking style of the cigarette is basically unchanged, and the smoke test results show that the ammonia in the mainstream smoke is reduced by 16% compared with the cigarette without the added tobacco filament, and the hydrogen cyanide is lowered. 15.5%, 3, 4-benzopyrene decreased by 40.7%, phenol decreased by 58.3%, crotonaldehyde decreased by 41.3%, CO decreased by 5.5%, nitrosamine decreased by 42%, and harmful components of sidestream smoke There is also a significant reduction, and the harm reduction effect is remarkable.

It can effectively reduce the release of harmful substances in the mainstream smoke and sidestream smoke of cigarettes, and at the same time alleviate the tight supply of tobacco raw materials in the tobacco industry, with great social and economic benefits.

Abstract

La présente invention a trait à un flocon de cigarette, à son procédé de préparation et à une cigarette. Le flocon de cigarette est préparé à partir de sous-produits agricoles. Le procédé de préparation comprend les étapes suivantes : les sous-produits agricoles sont trempés dans de l'eau à une température de 60 à 80 °C ou dans de l'eau à température ambiante de manière à obtenir des sous-produits agricoles enflés; les sous-produits agricoles enflés sont transformés en fibre de manière à obtenir une fibre grossière desdits sous-produits; la fibre grossière des sous-produits agricoles est lavée dans de l'eau à une température de 60 à 80 °C ou à température ambiante de manière à obtenir la fibre des sous-produits agricoles; la fibre des sous-produits agricoles est traitée par broyage de manière à obtenir une pâte des sous-produits agricoles; la pâte des sous-produits agricoles ainsi qu'une pâte à fibres renforcées traitée par broyage sont transformées en une pâte finie puis transformées en une base floconneuse. La base floconneuse est transformée en un flocon de cigarette après un premier séchage, un enrobage et un second séchage. Le flocon de cigarette de la présente invention, lorsqu'il est utilisé dans une cigarette, permet de résoudre les problèmes rencontrés dans l'état antérieur de la technique tels que l'instabilité et l'effet limité de réduction des risques, tout en permettant d'atteindre un objectif de réduction des risques.
