Abstract
A method for quickly conditioning a mass of tobacco uniformly throughout the mass with steam for the purpose of moisturizing and heating the tobacco evenly throughout. A probe is provided to be inserted within the mass of tobacco for drawing a vacuum while steam is applied to the tobacco mass. A temperature sensor is mounted on the probe to indicate the temperature of inner mass of tobacco. Steam is applied until a desired temperature is sensed at the sensor. The application of steam is continued at that temperature for a period adequate to moisturize and sterilize the tobacco throughout.
