Startup and Operation
This section will help you understand what the dryer is doing during operation from a cold start. There are 3
concurrent operations. Heating, Vacuum and, Retention. Cold startup begins with Preheat. Preheat only
occurs before the first cycle of the dryer’s initial startup, otherwise each cycle begins with material heating.
The vacuum operation pulls and holds a vacuum on the material for at least the Vacuum Time Set-point (or
longer if material remains in the Retention Hopper). The Retention operation holds the dried material in the
Retention Hopper. If equipped with the optional membrane air dryer, the material will be blanketed with hot
dry air until it is conveyed away.
Important: Inspect the VBD, verify that machine is clear of all material from heating hopper, Vacuum
Chamber and Retention Hopper. To facilitate a Clean Out, use the Clean Out function accessible from the
home screen.
Startup and Operation Instructions
1. ENSURE HATCH IS CLOSED . There is a hatch located on the
upper Heating Hopper. Ensure all 3 latches are closed. Also,
be sure the removable Lower Retention Hopper is in place.
2. Load material into the Upper Heating Hopper. Wait for the
Heating Hopper to fill with material before starting the Dryer.
3. Turn on Main Power by rotating the 25 AMP Main Disconnect
Handle to the Red ON position. This powers up the VBD-150
Dryer.
On initial power up of the VBD, the Control Panel powers ON
automatically. If the main power is ON but the Control Panel is
OFF, press and hold the Red Power Button located on the
Control Panel for 2 seconds. (Note: The VBD’s Control Panel
can be powered OFF without powering down the Main Power
by pressing and holding the Red Power button for 4 seconds).
