Sterlco MDB Series Dryers - Manual (Page 48)

5-3 Shutdown
1. Turn off the conveying system supplying the drying hopper.
2. When processing is complete, close the hopper slide gate and shut down any in-line
companion equipment, such as the aftercooler.
3. Turn the dryer ON/OFF selector switch to the SEQUENCE SHUTDOWN position. The
sequence shutdown operation turns off process heaters and keeps the process blower on
for twenty minutes to cool down the process. The regeneration cycle of the off-line bed
completes the cycle before the dryer shuts down completely.
4. To override the sequence shutdown turn the system ON/OFF switch to OFF.
5. To completely shut off the unit after sequence shutdown has completed, turn the system
ON/OFF switch to OFF.
6. If needed, empty the drying hopper.
7. For maintenance or a long term shutdown, open (de-energize) the electrical disconnects
at the dryer and at the power drop.
