Dryer External Connections

Once assembled, installation requires connection of: pneumatic air line, electrical, intake and
output material lines.

Compressed Air Connection

Connect an air supply to the air regulator’s IN port using a female
1/4” NPT pipe fitting.

An operating air pressure of 80 psi (5.5 bar) while the
vacuum generator is running is required for proper operation
of the Dryer. Setting the air pressure to 85 psi while the
machine is idle will usually attain the desired 80 psi while the
vacuum generator is running.

If your air supply has oil in it, add an oil separator (coalescing
filter). Oil in the air will combine with dust drawn from the
Vacuum Chamber forming a paste inside the vacuum generator.
It will stop working and require cleaning.

Observe the air pressure gauge to be sure the pressure
maintains 80 psi (5.5 bar) while the vacuum generator is running
as you check and adjust the regulator. If pressure drops below
80 psi, adjust the regulator. If the pressure cannot be maintained
at 80 psi (5.5 bar) while the vacuum generator is running, then
the air supply line is not adequate.

Do not supply Dryer with a lubricated air supply.
Damage to Dryer may result. Use only a clean,
dry, oil-free air supply.

Pinch Hazard - Keep fingers clear of seal
deck, the mating surface above the Vacuum
Chamber seal.

When air pressure is turned on and the
Vacuum Chamber Lift Switch is flipped up, air
cylinders lift the Vacuum Chamber off of the
slider rails and up to the seal deck closing the
gap between the top of the Vacuum Chamber
and the seal deck.

Confirm Correct 3-Phase Electrical Connection

THREE PHASE Unit - CONFIRM proper 3-Phase power connection prior to
loading material. Failure to confirm proper 3-phase connection can result in
reversed blower rotation and damage to blower if the blower sucks in material
from heating hopper rather than blow heated air into heating hopper.

To confirm proper 3-phase connection following these instructions:

Turn power on using main power switch.

There are two methods to confirm proper
3-phase connection:

Incorrect 3-phase connection will result in
reversed blower rotation. Both methods
for checking correct 3-phase connection
involve testing the blower rotation.

Method one requires the disconnecting the
2-inch hot air hose from the heating hopper
and manually turning on the blower. The
air from the blower should blow out of the
2-inch hose. Air should not suck into the
hose. If air does not blow out and sucks in,
the 3-phase connection is NOT correct.

Method two requires the removal of the left
side panel to view the blower and confirm
blower rotation on power up. Rotation
must be clockwise as indicated by the red
arrow.

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, blanketing
the material with hot, dry air, until the material 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).

4. After material has been loaded into the Heating Hopper,
select Run Dryer and press the ENTER button.

5. The display will show the Pre-Start screen. On this screen is:

Setpoint Temp – This is heat hopper inlet temperature. By the end of

the preheat cycle time, all material in the Heating Hopper will be
heated to this temperature. By default, the Setpoint temperature is set
to 150 °F. See Recommended Heat Temperatures on page 19 for
general temperature recommendations or contact the material
manufacturer.

Preheat Time – This is the duration of heating from a cold start.

Vacuum Time – This is the minimum duration of a vacuum cycle.

Actual vacuum cycle times will vary according to the throughput. The
default vacuum time is 20 minutes. In the vast majority of drying
operations, this time is adequate and does not need to be adjusted.
Special circumstances may require different vacuum times. Please
consult a Maguire Dryer Technical for additional information.

By default, START is selected (location of cursor). If the settings you

BD® - Vacuum Dryer®

Maguire Products, Inc.

What is happening when the dryer is running:

During the Pre-heat operation material in the heating hopper is brought up to temperature (T1s). Preheat
time is determined by the specified Preheat Time on the Pre-Start screen (timed preheat, default 35 minutes)
or by the Preheat Setup Auto option, which sets an inlet to outlet temperature delta and a minimum preheat
time.

After pre-heat, approximately one third of the material in the heating hopper is dispensed into vacuum
chamber, and the first vacuum cycle begins. Each vacuum cycle has a minimum vacuum time, set on the
Pre-start screen, or the main run screen (VTs). (default is 20 minutes).

The loader loads the Heating Hopper with new material as the Vacuum Chamber receives the heated material
and heating cycle begins concurrent to vacuum cycle (the first vacuum cycle is timed). The new batch of
material in the upper portion of the heating hopper will take less time to heat. Minimum time in the heating is
dictated vacuum time.

After first vacuum cycle, material is then dispensed into retention hopper ready for use. Material in the
retention hopper is blanketed with dry air.

The rate of consumption of dried material from the retention hopper ultimately dictates the amount of time that
the material will be preheated and under vacuum. Examples: If it takes 25 minutes to deplete the retention
hopper, the vacuum cycle will run past its 20 minute setpoint (pre-start screen) to 25 minutes. This is normal
operation. However if the retention hopper is depleted in 15 minutes and the vacuum time is set to 20
minutes, there will be a 5 minute window where no material is available. This indicates that the throughput of
the dryer has been exceeded. If the Throughput Alarm is enabled (Alarm Setup), a Throughput Alarm (Alarm
Code 20) will be triggered.

Drying is accomplished when all material reaches the proper
temperature, and is then placed under sufficient vacuum for a sufficient
period of time.

Measurement of moisture content of material, both prior to and after
drying, is accomplished by using a moisture analyzer.
