Embodiment 1

[0030] Place the cage containing 200 Kg of shredded cigarette tobacco in a closed extraction container, and inject liquid CO into the container. 2 As the extraction solvent, add absolute ethanol as an entrainer, adjust the temperature of the extraction kettle to 30°C, adjust the extraction pressure to 20Mpa, completely immerse the shredded cigarette tobacco, adjust the rotation speed of the cage to 40r / min, and rotate the extraction time for 20min. After the extraction, During the process of solvent removal, the temperature in the extraction container is kept at 20°C, the liquid solvent is drawn out from the lower part of the container, and the vaporized solvent is drawn out from the upper part of the container. After the extraction is completed, the cut tobacco is processed in a 150KW microwave for 220s Solvents in tobacco leaves.

Embodiment 2

[0032] Place the cage containing 200 Kg of tobacco leaves in a closed extraction container, and inject liquid CO into the container. 2 As the extraction solvent, add absolute ethanol as an entrainer, adjust the temperature of the extraction kettle to 30°C, adjust the extraction pressure to 20Mpa, completely immerse the finished tobacco leaves, adjust the rotation speed of the cage to 40r / min, and rotate the extraction time for 20min. After the extraction, The leaves were placed in hot air at 100°C for 10 minutes to remove the solvent in the tobacco leaves.

Embodiment 3

[0034] Put the cage containing 200 Kg of finished tobacco leaves in a closed extraction container, inject liquid dimethyl ether into the container as the extraction solvent, and inject acetone as an entrainer, adjust the temperature of the extraction kettle to 40°C, and adjust the extraction pressure to 30Mpa , completely immerse the finished tobacco leaves, adjust the rotating speed of the cage to 20r / min, rotate the extraction time for 25min, after the extraction is completed, extract the vaporized solvent from the upper part of the container, take out the finished tobacco leaves from the container as a whole, and place them in a 200KW microwave for processing 150s to remove the solvent in the 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...
