Abstract:

A dry-method reconstituted tobacco having adjustable and controllable air permeability and tightness, and a preparation method and an application of the dry-method reconstituted tobacco. Aiming at loose and porous structural characteristics and the characteristics of variable pore size of a dry-method reconstituted tobacco base structure, the particle size of solids (tobacco particles) in a coating liquid is changed to fill up the pores of different pore sizes, so that first-level adjustment and control of air permeability and tightness is achieved; second-level adjustment and control of air permeability and tightness is achieved by adding a section of roll coating, dip coating or curtain coating, slit coating and other coating modes after spray coating; and surface finishing and thickness adjustment of the reconstituted tobacco are performed by adjusting the moisture and pressure during press polishing, so that third-level adjustment and control of air permeability and tightness is achieved. According to the dry-method reconstituted tobacco, the air permeability and the tightness of the reconstituted tobacco can be reasonably adjusted and controlled according to the requirements for high, medium, and low sensory quality during heating a cigarette product, thereby satisfying the quality requirements for the smoke characteristics during heating a cigarette.
