(54) METHOD FOR THE PRODUCTION OF RECONSTITUTED TOBACCO


(57) Method for producing reconstituted tobacco characterized in that:
- the solid components of tobacco are comminuted to bring them to a particle size of about 20 - 220 µm, preferably about 80-180 µm,
- the comminuted product thus obtained is mixed with water, at least one binding agent and at least one material to form an aerosol until a mixture with a liquid content of about 30-50%, preferably about 35-40%, is obtained.
- said mixture is subjected to a first lamination in order to obtain a strip of continuous thickness of about 1-20 mm, preferably about 1 -10 mm,
- said strip, already subjected to said first lamination, is subjected to a series of further rolling passages, to obtain a strip having a substantially constant thickness of approximately 90 - 280 µm, preferably about 140-200 µm,
said strip is dried to bring its liquid content to about 8-15 %.
