Description

Technical Field

[0001] The invention belongs to the field of analytical chemistry, and in particular relates to a device and a method for preparing plant particles. Background Art

[0002] As cigarette consumers pay more and more attention to their own health, how to reduce the harm of cigarettes while enhancing the sweetness of smoking cigarettes, increasing the comfort of smoking cigarettes, and improving the quality of cigarettes has become a hot topic of research and development for cigarette manufacturers.

[0003] At present, the most common way to improve the sweetness and comfort of cigarette smoking is to add plant particles into cigarette filters, which has achieved good results and received praise from consumers. There are two main ways to produce plant particles. One is to crush and screen the plant blocks to obtain particles of the required size; the other is to crush the plants into powder, then add adhesives to prepare them into particles. The disadvantage of the first method is that the finished particles have a green smell and the sweetness is not obvious; the disadvantage of the second method is that in addition to the green smell and the sweetness is not obvious, the added adhesive will also produce additional smells, which will have a certain impact on the sensory quality.
