Abstract
An improved direct or indirect fired drying kiln having a drying chamber, a burner for heating air, a ducting system in the drying chamber for distributing heated air, a fan for circulating heated air through the ducting system, and venting openings in the ducting system to release heated air to various zones of the drying chamber is provided. The kiln improvement involves providing temperature sensors in the drying chamber in communication with a system for automatically controlling and actuating the venting means in order to control the flow of heated air to each drying chamber zone to achieve any desired temperature distribution throughout the drying chamber. The system can also be operated manually.
