A kiln and method for drying material. The kiln includes a drying chamber, a heating system for heating air to be delivered to the drying chamber, and a ducting system for delivering heated air to the drying chamber. Fans are provided for establishing a low air pressure region and a high air pressure region adjacent the ducting system in order to generate a circulation flow of air throughout the drying chamber. The ducting system is arranged to deliver heated air only into the low air pressure region of the fan to ensure proper mixing of the heated air from the ducting and recirculated air. In a second embodiment, the fans are reversible to permit air flow through the drying chamber to be reversed.
