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