Granule and preparation method thereof

The invention discloses a particle. The particle is obtained through the following steps: adding a flavoring agent into expanded tobacco shred powder with the particle size of 30 to 100 meshes according to the weight ratio of 0.005 to 0.015:1; and regulating the water content to 8 to 10 percent. The particle can serve as new functional absorbing material for a filter stick, and can effectively have the action of absorbing and intercepting particle phase harmful ingredients in the smoke gas. The particle provides good and cheap raw material for a cigarette manufacturing enterprise to produce anew filter stick with improved quality and reduced harm; in addition, the particle solves the technical problem of waste utilization for the enterprise, and meets the requirements of environmental protection and resource conservation.
