Abstract
A rotary cut tobacco drier, comprising a heated rotary drier chamber having one or more inclined paddles arranged to lift and then drop material therein to be dried as the chamber rotates. The chamber is provided with an air inlet to which air is supplied by a blower through a heater and a duct. The chamber is also provided with an air outlet through which air is extracted from the chamber by means of an exhaust fan to pass to a cyclone duct separator. The air inlet and the air outlet are arranged so that there is a substantially constant flow of air between them. A pivoted damper flap is provided to control the humidity of the air entering or in the chamber, an increase in humidity decreasing the rate of drying in the chamber.
