Abstract: A tobacco enhancement apparatus and a method of enhancing tobacco using the apparatus comprising a tunnel (12) having a vibratory conveyor floor (18), and an inlet (14) for receiving unexpanded tobacco shreds. A steaming and swirling station (32) is located downstream of the inlet and comprises an array of overhead steam nozzles arranged above the floor for steaming and expanding the shreds. The steam nozzles are positioned and angled to create vortices amongst the shreds. A conditioning venturi station (50) is located downstream of the steaming station for prolonging the exposure of the expanded tobacco shreds to conditions of increased vapor pressure. A set point controller (198) is provided for automatically monitoring and adjusting the downward angle of the steam nozzles, the steam pressure, the height of the nozzles, the height of the venturi station and the temperature of the expanded tobacco.
