3.3.1 C-50 DeDuster®
The C-50 DeDuster® is comprised of multiple components as listed in
Figure 2. The Integrated Product Feeder assembly controls the product
throughput into the C-50 DeDuster®. The Dust Collector assembly
collects the removed dust and releases clean air to the atmosphere (as
described in 3.3.3). The Pressure Regulator controls the air flow through
the vacuum generator and ionizer assembly (as described in 3.3.4).
The Integrated Product Feeder Assembly consists of:
•A Drive Block that connects the actuator to the Flow Cone that
regulates solids flow into the DeDuster®.
•A Pneumatic Cylinder which controls the movement of the Drive
Block.
•Air Flow Controls on the Pneumatic Cylinder that control the upward
and the downward movement of the Flow Cone.
oThe TOP air flow control valve determines the total upward
travel of the flow cone.
oThe BOTTOM air flow control valve determines the total
downward travel of the Flow Cone while feeding.
•An integrated Solenoid Valve and Timer controls the oscillation of the
Flow Cone which in turn controls the material flow rate into the C-50
DeDuster®. These are not adjustable.
•The movement of the Flow Cone determines the product throughput.
•The product flow is stopped when the Flow Cone is held at the bottom
position by the pneumatic actuator.
•The frequency of the Flow Cone oscillation is not changed. The
material flow rate through the C-50 DeDuster® is changed by
adjusting the TOP air flow control valve.
The C-50 DeDuster® separates unwanted dust from granular products.
In general, the cleaning performance of the C-50 DeDuster® is influenced
by:
•Material Flow Rate
oIncreased rate: lower cleaning efficiency
oDecreased rate: higher cleaning efficiency.
•Air Flow Through Compressed Air Pressure Regulator
oMore air will increase cleaning performance but also increase
the amount of good material carried over to the dust collector.
oLess air will minimize carry over but decrease cleaning
performance too.
oFind an optimum air pressure setting to achieve optimum
cleaning performance and acceptable carryover.
Please see section 6.2.2 for a detailed description of the Integrated
Product Feeder Setup.

3.3.3 Dust Collector Assembly
The Dust Collector Assembly separates and collects the dust that was
removed from the product by the C-50 DeDuster®. Centrifugal force
separates the dust from the exhaust air in the Cyclone and the dust is
collected in the Dust Container below. The air is then ejected from the
unit through the Outlet Air Filter. The Outlet Air Filter is protected by the
Outlet Air Filter Cover.
See the Spare Parts List in Section 10 for replacement part numbers.

3.4 How It Works
Product is gravity fed through the C-50 DeDuster®. Cleaning air is pulled
through the DeDuster® from the bottom by the integrated compressed air
operated vacuum generator. Unwanted dust is separated from the
product and collected in the Dust Container.
Figure 5: C-50 DeDuster® Operation
1. Controlled Feed Zone: A pneumatically driven flow cone maintains a
steady feed rate of the pellets into the C-50 DeDuster®.
2. Ionizing Zone: Compressed air uniformly distributes negative ions from
the Ion Generator to neutralize the static charge that holds dust on the
surface of the pellets.
3. Venturi Zone: A compressed air operated vacuum generator creates the
counter flow air stream that separates streamers and dust from the falling
pellets.
4. Air Inlet: If the outlet of the DeDuster® is closed off to the atmosphere,
then an air inlet on the side of the DeDuster® allows the vacuum
generator to pull in filtered air from the atmosphere.
5. Dust Collector: Unwanted dust and streamers are sent to the attached
mini dust collector. Filtered air is released to the atmosphere.

Cleaning Process After falling through the Integrated Product Feeder,dusty product passes
by an Ion Generator that disrupts the electrostatic charge between the
product and the dust.
The dusty product then enters the Venturi Zone where the cleaning air
separates dust particles and angel hair from the product. The counter
flow air speed in the Venturi Zone is controlled using the Air Pressure
Regulator.
Clean product exits the C-50 DeDuster®downward. The level of product
in the hopper below the C-50 DeDuster®is maintained using the
integrated Level Sensor installed on the Sight Glass below the
DeDuster®
Material is typically fed to the C-50 DeDuster® Inlet Hopper by a separate
Flapper-type Vacuum Loader.
Dust Separation The exhaust air from the C-50 DeDuster®is directed to the Cyclone
Assembly where the dust is separated from the air stream and collected
into the Dust Container. The air then passes through the Outlet Air Filter
and is released to the atmosphere.
See the Spare Parts List in Section 10 for replacement part numbers.
Compressed Air
