Abstract

A kiln controller controls the drying of lumber in a kiln by executing a drying schedule and adjusting the drying schedule in response to actual measured conditions in the kiln. A computer within the controller controls heating coils, spray nozzles and vents in the kiln to achieve the conditions prescribed in the drying schedule. The computer first executes a routine whereby the kiln temperature is brought up to a desired initial temperature. Then the computer concurrently executes the drying schedule and a routine wherein it monitors the temperature, vent load and spray nozzle activity, and automatically adjusts the duration of the current step in the drying schedule.
