Zusammenfassung:	A METHOD OF AND AN APPARATUS FOR EXPANDING TOBACCO, PARTICULARLY TOBACCO IMPREGNATED WITH SOLID CARBON DIOXIDE ARE DISCLOSED. THE APPARATUS COMPRISES AN ARCUATE, GENERALLY C-SHAPED DUCT FOR CONVEYING THE TOBACCO MATERIAL IN A HOT GASEOUS MEDIUM TO SUBLIMATE THE SOLID CARBON DIOXIDE AND EXPAND THE TOBACCO. THE DUCT HAS A NON-CIRCULAR CROSS-SECTION, PREFERABLY A RECTANGULAR CROSS- SECTION, WITH A HIGH WIDTH-TO-DEPTH RATIO AND AN INCREASING DEPTH FROM THE INLET (34) TO AN INTERMEDIATE PORTION OF THE DUCT (16) THEN A DECREASING DEPTH FROM THE INTERMEDIATE PORTION TO THE OUTLET (35) OF THE DUCT (16). A WINNOWER DEVICE INFEEDS THE TOBACCO MATERIAL INTO THE DUCT (16) ADJACENT THE THROAT OF A VENTURI SECTION CONNECTED TO THE INLET (34) OF THE CONVEYING DUCT (16). A TANGENTIAL SEPARATOR WITH AN ADJUSTABLE BAFFLE AT THE INLET (34) THEREOF FOR CONTROLLING VELOCITY IN THE SEPARATOR IS USED TO SEPARATE THE EXPANDED TOBACCO FROM THE GASEOUS MEDIUM.
