Abstract
A grain dryer control system uses the grain dryer discharge temperature to account for moisture reduction in the grain as it cools after discharge from the dryer. The control system includes moisture and temperature sensors and a means to control the discharge of grain from the grain dryer. Given a grain discharge temperature, a control temperature and a moisture reduction factor as a function of temperature, the control system calculates an expected moisture reduction in the grain as the grain cools. Grain is discharged from the dryer when the target moisture content after cooling added to the expected moisture reduction in the grain as the grain cools meets the measured grain moisture content in the dryer.
