Chapter 7: The Continuous Flow Drying Process
To set the 1-speed temperature scheme in continuous flow:
1. If the dryer is running, press Stop on the control panel.
IMPORTANT: To stop the dryer when connected remotely, click Stop Dryer from the main menu.
However, once stopped, you cannot restart it remotely. The dryer can only be
restarted on-site.
2. From the menu pane, click Control→Moisture Control Settings.
3. Set the following parameters:
Unload Speeds Entered in — The units of measure (bushels or metric tons per hour, or metering
roll speed %) that the unload speed value is entered in.
NOTE: The units of measure selection (bushels or metric tons per hour) that is displayed in this field
is dependent on the chosen system of measurement (System→Preferences→Units of
Measure).
Grain setpoint — The grain’s target temperature value. This setpoint is the reference parameter that
is used to determine your dryer’s unload rate.
Speed — The desired metering roll speed used to obtain the target grain temperature. If the grain
temperature is equal to, or rises 1°F (0.56°C) above its setpoint, the metering rolls turn at this speed
setting; 1°F (0.56°C) below the setpoint, the metering rolls automatically stop turning.
Let’s assume that you enter a grain temperature setpoint of 105°F and a speed setting of 300 Bph. If the
grain temperature is equal to or greater than 105°F, the metering rolls turn at 300 Bph. If the grain tempera-
ture drops to 104°F, the metering rolls stop turning.
After You Finish
Now that the control scheme is set, complete the procedure on drying grain in continuous flow mode (see
Drying Grain in Continuous Flow, page 57 ).
Setting the 2-Speed Temperature Scheme in Continuous Flow
To achieve the target moisture content using the grain temperature and two absolute metering rolls
speeds, you can select the 2-speed temperature control scheme as a precursor to the more comprehen-
sive 5-speed schemes.
Before You Begin
Make sure to select the 2-Speed Temperature control scheme in the Moisture Control Mode window (see
Drying Grain in Continuous Flow, page 57 for details).
To set the 2-speed temperature scheme in continuous flow:
1. If the dryer is running, press Stop on the control panel.
IMPORTANT: To stop the dryer when connected remotely, click Stop Dryer from the main menu.
However, once stopped, you cannot restart it remotely. The dryer can only be
restarted on-site.
2. From the menu pane, click Control→Moisture Control Settings.
3. Set the following parameters:
Unload Speeds Entered in — The units of measure (bushels or metric tons per hour, or metering
roll speed %) that the unload speed values are entered in.
