More Information
Summary: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.
