Abstract

An apparatus and method for drying reconstituted tobacco sheets includes positioning a steam box below an endless conveyor belt. A slurry is cast onto the conveyor belt and conveyed over a steam box before entry into a drying apparatus. The steam box functions to pre-treat the slurry so as to increase the rate by which the slurry may be dried. The steam box includes the use of a perforated plate which encloses an upper portion of the steam box and which functions to uniformly distribute steam to the underside of the conveyor belt.
