6. When drying dirty corn in high humidity conditions, sludge may build up in the upper outside sheets
of the dryer. This build up can be removed by either washing the sheets down with a high pressure
water hose or by shutting incoming grain, dropping the grain level to below the plugged area and
then running the fans and burner to dry the affected area. Tapping or sweeping the sheets will
dislodge debris. Attempting to sweep off the sheet build up while it is still wet will usually plug the
sheet more.
In Case of Fire
1. When you first detect a fire, the entire drying operation should be shut down, including grain flow
into and out of the dryer. The emergency controls may have already done this. Also, shut off the
electrical and fuel supply to the dryer.
2. Do not try to cool a fire by running fan(s).
3. Never run grain from the dryer into the elevator or storage if a fire is known or suspected.
4. Locate the area of the fire.
5. If the fire can be extinguished with a fire extinguisher, water hose or by removing the burning
material, this should be done right away. Watch the dryer closely for another fire after one
has occurred.
6. Emergency discharge slide gates at the bottom of each column as well as easy access gates
located near the hopper discharge area permit fast dumping of each individual grain column.
7. A fire extinguisher should be located at or near the dryer, if a fire seems to be getting out of control
call the fire department.
End of Season Service
1. Empty the dryer at the end of the drying season. The dryer should not be used for grain storage.
Grain left in there for an extended period of time can become wet, swell and spoil. Chunks of
spoiled grain can plug the metering system and swelled grain places undue stress on the interior
and exterior sheeting of the dryer.
2. Clean out the plenum roof grain cushion and remove any grain that may be hanging up on the
plenum roof.
3. Make sure the grain exchangers are clean.
4. Clean out the hopper that divides the heat section from the cooling section.
5. Clean the cooling chamber floor.
6. Remove all grain and trash from the metering drum floor. This grain can be raked out by hand by
opening the slide gates located in the hopper bottom of the dryer.
7. Make sure gas supply is shut off to the dryer.
8. Open the gas train drain valve located on the bottom of the gas train.
9. It is a good practice to cover the burner with a tarpaulin or plastic to ensure a clean burner.
