Wherein the heating non-combustible tobacco product is the product which is closest to the traditional cigarette in the aspects of smoking quality and smoking habit, and the development prospect is good. The technology for heating the non-combustible tobacco is that the tobacco is heated at the temperature of 200-400 ℃ through a smoldering carbon rod or a heating electronic element, so that the tobacco is not combusted, but the components of the tobacco can still be distilled and cracked, and the smoke is released.
Compared with the traditional tobacco product burning, the cigarette which is not burnt after being heated has the advantages that the released harmful ingredients are obviously reduced compared with the traditional cigarette because the burning does not occur, and the product safety is obviously improved under the condition that the smoking quality is close to that of the traditional cigarette, so the technology has good development prospect and market potential. Compared with the traditional cigarette, the cigarette has higher requirement on the filter stick when being heated and not combusted, and is different from the traditional cigarette filter stick and only has the function of filtration and interception.
