Initial Startup Procedures (Empty Dryer) from MEYER®
IMPORTANT! This procedure assumes that all pre-startup inspections and preparations have been made.
- Turn ON the Electrical Service Disconnect and the Dryer Equipment Disconnect.
- Turn ON the fuel Main and Pilot Inlet Valves. If propane fuel is used, open fuel tank valves. Slowly open the gas valve at the LP tank or natural gas supply line to its full open position. This is especially important with LP gas to keep from “flashing” or freezing the line as the liquid propane expands from the highly pressurized tank into the unpressurized fuel line.
-
The Dryer can be started with
Dry Grain or Wet Grain
methods. Have the grain’s loading path set for the desired initial fill method.
- Filling with dry grain will result in some over-drying of the grain. This is the preferred method if the wet grain supply is above 20% moisture.
- Filling with wet grain will result in some grain being discharged too wet. Under-dried grain should be recycled back to the wet tank if such a grain path is available.
-
Turn on the QUANTUM
®
Control Monitor. Under the ENABLES Menu, push arrow keys to:
- Enable Load; enable Fan. To keep dust out of the Burner during filling, disable Unload.
- Push the START button on the QUANTUM® (lower right-hand key). See right.
-
Push the START on the Dryer red Control Panel.
- On “Demand Fill” systems, Fans should start and grain fill should begin.
- On “Choke Fill” systems, the fill conveyor/leg will need to be turned on, or grain will need to be directed to the Dryer to begin filling.
6. The filling process may take 30-60 minutes to complete on the initial fill. When the Wet Grain Level Switch has been satisfied:
- The QUANTUM® Monitor LOAD Status changes from ON to ENABLED.
- A wet sensor moisture reading will appear on the QUANTUM® Monitor STATUS screen after the Unload is running.
- In the Control Panel box, the IO panel red input light labeled “Low Grain Switch ON” will be OFF.
7. Inspect the inside of the Dryer:
- Shut off the Dryer and turn off the Dryer Disconnect. Follow LOTO procedures. See Disconnecting Procedures in the Owner/Operator Manual.
- Inspect the inside of the Dryer for dust or debris on the heating floor and in the Burner. Clean as required.
- Turn on the Dryer Disconnect and start QUANTUM® Controls to continue.
8. Dry Grain Start: Starting the Dryer when it is initially filled with dry grain.
- Change the grain path to direct wet grain to the Dryer’s fill spout.
- With the Fans and Load still enabled, set the Drying Mode to MANUAL, the Unload Rate speed to approximately 50%, and enable the Unload.
- Unload grain without the Burner for about thirty (30) minutes at 50% rate. During this time period, sample the outgoing grain.
- At the end of the thirty (30) minutes, light the Burner as follows.
- Set the maximum plenum temperature. Set the maximum auxiliary unload rate limit according to the grain being dried and based on what your unload equipment can handle.
- Set the desired outlet target moisture.
- Enable the Burner.
- Open the manual Maxon shutoff valve.
- A thirty (30)-second purge time will begin.
- First the Burner pilot, and then main flame should ignite.
- An increasing plenum temperature on the QUANTUM’s STATUS screen should be observed. It may take several minutes to reach full operating temperature.
v. Set the moisture control Mode to AUTO.
e. The Dryer will begin automatic control of the unload rate and plenum temperature to reach the preset outlet target moisture.
- Continue sampling dry grain until moisture samples are close to those indicated on the calibrations screens.
- It may take 2-3 Dryer passes for the discharge moisture to stabilize on target. Try to avoid interrupting this stabilizing process by stopping the Dryer, changing control modes, or changing other parameters that will re- initialize the learning process.
9. Wet Grain Start: Starting the Dryer when it is initially filled with wet grain.
- With the Fans and Load still enabled, the Unload disabled, and the Drying Mode to MANUAL, begin a batch drying process.
- Light the Burner as follows:
- Set the maximum drying temperature limit. Set the manual plenum temperature under the DRYING MODES menu.
- Enable the Burner.
- A 30-second purge time will begin. Reset the Maxon shutoff valve during this period.
- First the Burner pilot, and then main flame should ignite.
- An increasing plenum temperature on the QUANTUM’S STATUS screen should be observed. It may take several minutes to reach full operating temperature.
c. Batch-dry grain (with unload OFF) for approximately 4 minutes per point,
i.e., 20% to 15% moisture = 5 points, 5 points x 4 minutes = 20 minutes
d. At the end of the batch drying time;
- Set the desired outlet target moisture.
- Set the moisture control Mode to AUTO.
- Enable the Unload.
e. The Dryer will begin automatic control of the unload rate and plenum temperature to reach the preset outlet target moisture.
- During the first grain pass, you may want to return any under-dried grain to wet storage.
- Begin the Moisture Sensor calibration process. Wait until the discharge moisture is within two (2) points of target before attempting to calibrate the discharge moisture sensors. Continue until moisture samples are close to those indicated on the calibrations screens.
- iIt may take 2-3 Dryer passes (approximately 3-4 hours at 50% rate) for the discharge moisture to stabilize on target. Try to avoid interrupting this tuning process by stopping the Dryer, changing control modes, or changing other parameters that will re-initialize the learning process.
10. Grain discharge temperatures can be adjusted by changing Louvered Air Inlets. See your Owner/Operator Manual.
Service Light (Red Control Panel)
If the outside temperature is below 32 degrees F:
To keep electrical control circuit components warm, turn on the Service Light at least one hour prior to daily startup (or leave on overnight). Do not use this light in the daytime if the temperature is above freezing (32 degrees F).
