How often do I make speed

adjustment? See step number

ten in the Full Heat-Continuous

Flow Operation section.

START UP PROCEDURE

The vaporizer can be adjusted two ways. First, by loosening the bolt in

the hinging mechanism and swinging it to a hotter or cooler position.

Second, by loosening the two bolts in the hinge pipe and sliding 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 tem-

perature. Natural gas does not use a vaporizer.

FULL HEAT-CONTINUOUS FLOW OPERATION

1 . Look in your operators manual in the DRYER START UP section (CON-

TINUOUS FLOW METER ROLL SETTINGS-FULL HEAT). You will

see the settings for (Initial Moisture) (Moisture Removed) (Approx. Dry

Time) (1 Speed) (2 Speed Low) (2 Speed High) 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 (APPROX.

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

METER ROLL SPEED, (HIGH SPEED) pot. 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 (APPROX. 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, over dry some of

t h e c o r n a l i t t l e .

7 . Increase the drying temperature to 190 deg. for single fans or for mul-

tiple fan dryers set the heat chambers 30 to 60 degrees 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 deg.

10. Turn the UNLOAD to 2 SPEED. Set the METER ROLL SPEED, LOW

SPEED and HIGH SPEED pots. to the settings listed for them. Let the

dryer run on these settings as shown in the example #5 before trying to
