A METHOD FOR MAKING A RECONSTITUTED TOBACCO SHEET USING STEAM EXPLODED TOBACCO

摘要

Process for improving the mechanical properties of the quality of the reconstructed tobacco smoke is achieved by the addition of a tobacco raw material in an aqueous solution containing an ammonium salt and urea. Then, the first tobacco slurry obtained as a result is pressed for at least 1 to 5 minutes at a steam pressure of 60psi action, it is rapidly depressurized to atmospheric pressure followed. Subsequently, the pressure-cigarette is formed of a second tobacco slurry with the soluble components in the cigarette removed. Then, the resulting residue cigarettes is a reconstructed tobacco sheet prepared, following extracts are concentrated to a level of solids of about 30% by weight, which is added back to the reconstructed tobacco sheet to be processed further in a smoking article.
