The present invention belongs to the technical field of new tobacco products, and particularly relates to a sucking particle for heat-not-burn cigarettes and manufacturing method.
At present, the main tobacco fillers of heat-not-burn products in the market are cut tobacco, slurry process-based tobacco sheet and paper-making process-based tobacco sheet, which are heated and atomized by a special electric heating apparatus to deliver the feeling of smoking to smokers. The electric heating temperature is 250-310° C. generally, far lower than the cigarette burning temperature of 700-800° C.
There are some common problems of the heat-not-burn materials. For example, due to the relatively high density of the tobacco fillers some of which have a relatively high content of wood pulp fibers and other components, the tobacco fillers are slowly heated and have poor heat conduction, or due to the shape of tobacco, heating is not uneven and therefore the feeling of smokers smoking traditional low tar cigarettes cannot be achieved, or due to no tobacco specific physiological taste adjusting components are added, there is a great difference between the resulting physiological satisfaction and that from smoking traditional cigarette products.
At the same time, there are some problems in the processing technology of tobacco fillers of heat-not-burn cigarettes. For example, the Chinese patent CN104366687B discloses that raw tobacco materials are preliminarily pulverized into powder with a pulverizer, the length of the powder is less than 2 cm and the diameter is less than 0.2 cm, and the powder obtained is put into a microwave expansion equipment for microwave expansion at a single tube power of 1.5 KW and a high frequency of 2,450 MHz for 20-40 minutes to obtain the expanded semi-finished particles. This process is common at present. However, by microwave expansion or steps in which the processing temperature is high, the tobacco aroma substances are prone to lose, making it unable to experience the aroma of traditional low tar cigarettes.
In view of the disadvantages of the prior art, the present invention aims to provide a sucking particle for heat-not-bum cigarettes and a manufacturing method to overcome the defects of a sucking product for heat-not-burn cigarettes of the prior art.
