QUICK START UP PROCEDURE

How often do I make speed adjustment? See step number ten in the Full Heat-Continuous Flow Operation section.

the burner from the regulator are warm to the touch (not hot and cold). The vaporizer can be adjusted two ways:

•Loosen the bolt in the hinging mechanism and swing it to a hotter or cooler position, or

•Loosen the two bolts in the hinge pipe and slide the vaporizer in or out to a cooler or hotter position.

Either one or both methods may have to be used to get the vaporizer to the proper temperature. Natural gas does not use a vaporizer.

FULL HEAT-CONTINUOUS FLOW OPERATION

1.Check the Continuous Flow Metering Roll Settings-Full Heat on page 25. Pick the line that has your initial starting moisture. These are the settings we will be referring to during this start up procedure.

2.Make sure the UNLOAD switch is OFF.

3.Make sure the MOISTURE CONTROL switch is OFF.

4.Run the fan(s) and heater(s) for about 10% longer than the approxi- mate drying time required for the moisture you are trying to dry.

5.Example: 10% removal would be about 54 minutes, 15% removal would be about 76 minutes and 20% removal would be about 100 minutes. Add 10 minutes to insure that the grain is dry.

6.After the time in step 4 turn the UNLOAD to 1 SPEED and set the METERING ROLL SPEED, HIGH SPEED potentiometer to the setting for 1 SPEED operation. Grain should begin to run at this time. Run time for this is about 10% longer than the approximate drying time required for the moisture you are trying to dry, as shown in the example #5 above. This allows the moisture in the dryer to reach an even gradient top to bottom without having any highs or lows in it. It will, however, overdry some of the corn a little.

7.Increase the drying temperature to 190° for single fans or for multiple fan dryers set the heat chambers 30° to 60° apart. Hottest at the top, most cool at the bottom.

8.DO NOT TRY TO ADJUST THE DRYER FOR MOISTURE DURING THIS PROCESS OR YOU WILL ESTABLISH HIGH AND LOW SWINGS IN THE MOISTURE CONTROL. IT WILL TAKE SEVERAL HOURS TO WORK ITSELF OUT.

9.After the run time in step 6 you are ready to set up the moisture control. Now turn the MOISTURE CONTROL to the ON position. Set the tem- perature to about 100°.

10.Turn the UNLOAD to 2 SPEED. Set the METERING ROLL SPEED, LOW SPEED and HIGH SPEED potentiometer to the settings listed for them. Let the dryer run on these settings as shown in the example #5 before trying to adjust moisture or meter roll settings. These settings
