Cigarette tar-reducing harm-reducing process and supercritical extraction device for tobacco shred or tobacco leaves

Abstract

The invention belongs to the technical field of cigarette production, and particularly relates to a cigarette tar-reducing harm-reducing process, which includes placing tobacco shred or tobacco leaf in a rotating device for supercritical fluid extraction, and treating the extracted tobacco shred or tobacco leaves by microwave or hot air at 80 DEG C-150 DEG C after extraction. By the cigarette tar-reducing harm-reducing process, main aromatic ingredients of the tobacco leaf are maintained, and nicotine or other harmful ingredient precursors in the tobacco leaf are selected lowered. By the cigarette tar-reducing harm-reducing process, cigarette quality can be improved, release amount of tar and harmful ingredients in cigarette smoke can be reduced, and cigarette safety can be improved.

Description

technical field

[0001] The invention belongs to the technical field of cigarette production, and in particular relates to a cigarette harm reduction and tar reduction treatment process and a device for supercritical extraction of shredded tobacco or tobacco leaves. Background technique

[0002] As early as the early 1950s, the Royal Society of Medicine publicly stated that smoking is harmful to health. In the late 1950s, both the U.S. Department of Health and the Royal Society of Medicine issued announcements that excessive smoking was one of the causes of lung cancer. In the 1990s, calls for smoking bans became increasingly louder, and the development of the world's tobacco industry has reached a critical period of survival. In order to survive and develop themselves and be responsible for human health, all countries have actively carried out extensive research on smoking and health issues. Therefore, along with the problems of smoking and health are more and more concern...
