Description: A computer-based control system for a batch-in-bin grain dryer was developed and tested with a farm-scale grain dryer in 1985. Nine drying tests were conducted with wet corn harvested at about 30% initial moisture content (wet basis). The control system utilized an inexpensive personal computer (Radio Shack TRS-80 Model 100) and an A/D interface unit designed to communicate with the computer through the RS232 port. The control algorithm was based upon simulation of the drying process, with known initial conditions and parameters. Control to within 0.3 percentage points of the target final moisture content of the corn dried was realized in three of the tests.
