Abstract

The utility model relates to a high temperature cracking device for tobacco leaves, which comprises a cracking quartz tube and a drum-type heater. The cracking quartz tube is arranged in the drum-type heater, a piston with a push rod is arranged on the air inletting end of the cracking quartz tube, two interfaces are arranged respectively on the cracking quartz tube, a first interface is connected with a protective air flow controller, and a second interface is connected with a vacuum circulating pump. The utility model can effectively eliminate oxygen interference in the air, and the tobacco leaves and other organics can be separated fully, which is beneficial to shorten cracking time, improve efficiency, and lower cost.

Description

technical field [0001] The invention relates to a pyrolysis device for high-temperature dry distillation of tobacco or other organic matter. Background technique [0002] Cigarettes are because consumers get some satisfaction from the smoke produced by smoking shredded tobacco. The components of smoke are formed by the complex processes of cigarette tobacco through combustion, distillation, dry distillation, pyrolysis and re-synthesis. When a cigarette is burned, its aroma is not only derived from the burning area of ​​the cigarette, but more importantly, from its dry distillation pyrolysis area. Therefore, the study of pyrolysis, dry distillation and re-synthesis of tobacco can systematically analyze other important aroma substances, including surface volatiles, pyrolysis products, and re-synthesis products, except the aroma substances directly released from the high-temperature combustion zone. From another aspect, further describe the combustion process of cigarettes an...
