Abstract
A dryer of the type having a burner for supplying a source of hot gas for drying material being tumbled. The apparatus provides a cool-down cycle for the dryer. A burner control circuit enables and disables the burner to supply hot gasses in accordance with a sequence which produces a substantially linearly decreasing temperature over time. At the end of the time interval a signal is generated indicating that the cool-down sequence has been completed. Each cool-down cycle starts from the same initial temperature as determined by the operator such that the final cool-down temperature for the same cool-down run time is the same.
