DRYER QUICk StARt-UP
These instructions assume that all safety checks and operational settings have been
made, the dryer has been inspected to make sure no debris is in the augers, columns
or metering rolls of the dryer and that the moisture control mode has been selected. If
you are unfamiliar with the various operations or want more specific instructions for
start-up, please refer to the complete manual for your model.
1. Before attempting to operate the dryer, ensure all safety shields are in place, all
plenum bottom closure panel doors are closed, all rear access doors are closed and
that all personnel are clear of the grain drying and handling machinery.
2. Turn all selector switches on the control panel to the OFF position.
3. Move the safety disconnect handle mounted on the dryer’s upper power box to On.
4. Turn on all fuel supply valves including any on the dryer, excluding the
Maxon valve.
5. Turn the Control Power Switch to On. Once the Boot Screen appears, select the
“Start Dryer” button.
NOTE: After the safety check, if the dryer is equipped with an electric Maxon
gas valve, it will be armed. If the Maxon valve is a manual model, move the
handle for the valve to allow gas flow.
6. Move the Load Switch to MAnUAL and push the Start Button. The top auger will
immediately start and fill the dryer.
7. After the dryer fills completely, turn the Load Switch to the AUTO position.
8. Turn each Fan Switch On. The fan(s) will start and switches will light up when sensing
air pressure.
9. Turn the Heater Switch(s) On to light the burners.
10. Confirm that all burners are set at 180°F (82°C) for start-up.
11. Refer to the All Heat or Dry & Cool time and manual speed charts to determine how
long to run the burners based on the incoming moisture. If running Dry & Cool after
running for the time specified, turn off the burner on the cooling fan(s) and allow to
run for 10 additional minutes.
12. Turn the Unload Switch to MAnUAL and set the Meter Roll Speed to the chart setting.
13. Increase the drying temperature(s) to your normal operating temperature(s).
14. Run in MAnUAL for a minimum of 6 minutes for each point of moisture
to be removed.
15. Turn the Unload Switch to AUTO.
DRYER SHUtDoWn
1. Turn OFF in sequence: Shutoff Load switch, then burners (top to bottom), then fans
(top to bottom), and finally the Unload switch.
2. Close the fuel supply valve at the tank or valve along the fuel line.
3. If the burner is operating, let the dryer run out of fuel and it will shutdown
automatically due to loss of flame.
4. Close the fuel valve at the dryer and press the dryer STOP button.
5. Turn OFF the Control Power Switch.
6. Turn OFF the safety disconnect handle on the front of the power box and turn OFF
the main power to the dryer.
Dry & Cool: This process cools the grain before it exits the
dryer, as the lowest fan is ran without the burner. This mode
cools the grain in the dryer for safe storage in bins with
standard aeration.
All Heat: Also referred to as Full Heat, this process
discharges grain hot without any cooling. All fans are
operated with their burners on. The grain must be cooled in
bins equipped with airflows higher than standard aeration
requiring additional management. Typically, 1%-3% of
moisture is removed in the cooling process. Therefore,
hot shelled corn should be removed from the dryer at
approximately 17% moisture if the final desired moisture
content is 15%. Each farm and each bin, depending on
conditions, practices and amount of airflow, will vary in the
amount of moisture removed. Once the moisture removal
of each bin is determined, it should be recorded for future
reference. Drying capacity is substantially higher using the
All Heat process versus the Dry and Cool process.
Shelled Corn: For shelled corn with an initial moisture
content of 20% -30%, the recommended temperature on a
two fan dryer is 230°F (110°C) for the top fan with the range
being 210°F – 240°F (99°C - 116°C). The recommended
temperature for the bottom fan is 180°F (82°C) with the
range being 170°F – 190°F (77°C - 88°C). If operating a two
fan dry and cool or a single fan all heat, the recommended
temperature is 210°F (99°C) with the range being 200°F –
230°F (93°C - 110°C).
Small Grain & Soybeans: For drying wheat, oats, milo and
soybeans, a temperature of 140°F - 160°F (60°C - 71°C) is
suggested. Settings may change from year to year.
Rice: For drying rice, a temperature no higher than 130°F
(54°C) is recommended.
NOTE: On dryers with Grain Inverters all burners must be set
for the same temperature.
For obtaining the highest drying efficiency, use the
highest possible drying temperatures which will not
adversely affect grain quality.
If the dryer is to be shutdown while filled with grain, it
is recommended that hot grain be cooled for a minimum
of 15 minutes, particularly in colder weather to prevent
water vapor condensation and possible freezing.
