Time Control Schemes in Staged Batch
If you use timers to control the drying phase in staged batch, you can apply different drying strategies
simply by adjusting the fan and heater switches and all applicable timers accordingly.
Drying Strategies for the Time Schemes in Staged Batch
• Full-heat versus dry and cool: Choose a full-heat strategy if you want grain to be unloaded hot and
uncooled; choose dry and cool if you want grain to cool the grain inside the dryer before the unload-
ing phase.
• Manual versus automatic: Choose manual mode (fans and heaters in the On position) if you want
the fans and heaters to continue running during the unloading phase; otherwise, choose automatic
mode (fans and heaters in the Auto position).
• Single-setpoint versus dual-setpoint control schemes: Choose a single-setpoint control scheme
if you want plenum temperatures to remain the same during the entire drying phase, or select a dual-
setpoint scheme to have the plenum temperatures switch from one value to another at a specific
point during the drying phase.
