DRYER OPERATION - START-UP
DRYER START-UP AND OPERATION
FULL HEAT DRYING
Full Heat Operation
With this type of drying, the grain is discharged hot, with no cooling. Drying capacity is substantially higher with FULL HEAT
than the DRY AND COOL process.
Final Moisture
From 1 to 3% apparent moisture is usually removed in the cooling process, so hot shelled corn is removed from the dryer at
about 17% moisture if the final desired moisture content is 15%.
DRYING TEMPERATURES
Shelled Corn
For shelled corn with an initial moisture content of 25-30%, the recommended maximum drying temperature is 220-240
o
F (104-
116
o
C) for the top fan and 170-190
o
F (77-88
o
C) for the bottom fan.
Small Grain
For drying small grain (wheat, oats, milo), 150
o
F (66
o
C) is suggested.
Soybeans
Drying temperatures are critical in drying rice and soybeans. A temperature of 130
o
F (54
o
C) is recommended to keep grain
temperature low.
Drying Efficiency
The general rule for obtaining the highest drying efficiency is to use the highest possible drying temperatures which will not
adversely affect grain quality.
DRYER SHUTDOWN
Cooling Hot Grain
If the dryer is to be shut down while filled with grain, it is recommended that hot grain be cooled for 10 to 15 minutes, espe-
cially in cold weather, to prevent water vapor condensation and possible freezing of such condensate following shut down.
INITIAL SETUP PARAMETERS
Turn the control power switch to on. When the Boot Screen appears touch the START DRYER button. The computer will run a
quick check of the system network after which the Operation Screen will appear.
TIMER AND DELAY SETTINGS
Setting the timers for the Vision Dryer is a simple procedure. To set the timers touch
the button at the bottom
of Operation Screen. A new screen will appear called the Select Timers to Modify screen (see page 13 for instructions on how
to set the timer and delays).
SETTING THE TEMPERATURES
Setting the temperature setpoints for the dryer is a simple procedure. To adjust the temperture setpoints touch the
button at the bottom of Operation Screen. A new screen will appear called the Select Temperature Setpoint to Modify screen
(see page 13 for instructions on how to set the temperatures).
START-UP
Start-up Procedure
At the beginning of each harvest and before filling the dryer with grain make sure to inspect the dryer for rodent damage, proper
belt and chain tension and missing or damaged safety shields. Test operate the dryer using the pre start check procedures.
1.
Before attempting to operate the dryer make sure that all safety shields are in place, all plenum bottom closure panel doors
are closed, all rear access doors are closed and all personnel are clear of the grain dryer and grain handling machinery.
2.
Turn all selector switches on the control panel to the off position.
