What is the D Carousel Dryer?

The D carousel dehumidifying dryer produces hot, low-dew point air that removes
moisture from hygroscopic plastics. The dryer pulls warm, moist air from a drying
hopper and pumps it through dehumidifying desiccant. The dryer then heats the air
to the drying temperature you selected and circulates it through the material in the
hopper.

The dryer’s three-tank, closed-loop design ensures a continuous supply of hot,
dehumidified air while preventing contamination from moisture in the plant.

Typical Applications

2-2 l Description

The D dryer can be
mounted beside the
hopper on the throat of a
processing machine using
the optional diving board
support frame, or
positioned on the floor
near the machine using the
standard casters. Two
mobile floor stand designs
are also available.

Dryer on a floor stand; hopper on the
throat.

Description

When supplied for central drying

applications, the D series dryer
is not equipped with a process
heater. Therefore, as a central
dryer, the D dryer will only sup­ply dry air to the hoppers.

Typical Applications (continued)

The D carousel dryer can be used successfully in applications that require:

• A contamination-free drying environment.

• Drying temperatures within the ranges shown in the following table:

Model Drying Temperature Range

Low temperature (with precooler)* 100° - 150°F (38° - 66°C)

Standard 150° - 250°F (66° - 121°C)

High heat (with aftercooler) 150° - 375°F (66° - 191°C)

Low-high (with aftercooler & precooler)* 100° - 375°F (38° - 191°C)

*Note: See instruction on page 4-12 for setpoints over 150°F (66°C).

• Throughput rates of 15 to 100 lbs (6.8 to 37.3 kg) per hour (some materials

can be run at a higher rate).

• Dew points of -40°F (-40°C).

If you are drying material at temperatures over 250°F (121°C), you will need the
high-temperature package that includes an aftercooler. An aftercooler is standard
equipment on the High heat and Low-high models.

Central

How It Works

The D carousel dryer achieves continuous, closed loop drying by passing air simul­taneously through two heaters and three tanks of molecular sieve desiccant.

THE

PROCESS (DRYING) CYCLE

The process blower pulls moist air from the top of the drying hopper. The air pass­es through the process filter (and optional aftercooler, if installed) into the dryer’s
desiccant tank, where moisture is removed. The now dry air moves through the
process heater, where it is heated to the drying temperature selected by the opera­tor. The hot, dry air is delivered to the hopper (after it passes through the optional
precooler, if installed) where a spreader cone evenly distributes the air through the
material.

The Cooling Cycle

A regenerated desiccant tank must be cooled before it is moved back into the
process cycle. The process blower pushes a small amount of air through the regen­erated desiccant tank. The cooling air then passes through the optional aftercooler,
if installed, and repeats the circuit.

The Regeneration Cycle

The regeneration blower pulls air through the regeneration filter into the dryer’s
regeneration heater. The air is heated to 425°F (218°C) before it is pushed into the
“wet” desiccant tank. The hot air purges moisture from the desiccant. The moist air
is blown out the exhaust at the back of the dryer.

SPECIFICATION NOTES:

*

SCFM stands for standard cubic feet per minute, referenced to a pre-specified pressure, temperature and relative humidity.In most
cases, SCFM is referenced to 14.7 PSIA 68° F and 0% relative humidity.ACFM stands for actual cubic feet per minute, and must be
supplied with a temperature reference, due to the change in air density with temperature.Because dryers operate at a relatively low
pressure the effects on air density are negligible.

†

Dryers running at 50 HZ will have 17% less airflow, and a 17% reduction in material throughput.

Specifications may change without notice. Consult a Conair representative for the most current information.

Unpacking the Boxes

The D carousel dryer comes in one to four boxes, depending on the model and
options ordered. The boxes could include (depends on options selected):

1 Carefully remove the dryer and components from their shipping containers,

and set upright. Note that the dryer is secured to its shipping container with
four bolts that pass through the bottom of the dryer frame. These bolts are
accessed by removing the side panels of the dryer.

2 Remove all packing material, protective paper, tape, and plastic, including any

inserted in the top section of the dryer. Be sure to remove the side panels from
the dryer and cut and remove three (3) tie wraps securing the bedplates. Also
cut and remove the tie wrap on the bedplate limit switch.

Preparing for Installation

The D carousel dryer is easy to install if you plan the location and prepare the
mounting area properly.

1 Make sure the mounting area provides:

❒❒

A grounded power source supplying the correct current for your dryer

model. Check the dryer’s serial tag for the correct amps, voltage, phase, and
cycles. Field wiring should be completed by qualified personnel to the
planned location for the dryer. All electrical wiring should comply with your
region’s electrical codes.

❒❒

A source of water, if you have an aftercooler and / or precooler.

The D dryer’s optional aftercooler and precooler can use 1-2 gals./min. (3.8-

7.6 liters/min.) tower, city, or chiller water at temperatures of 40° to 85°F
(4° to 29°C). Pipe should be run to the planned dryer location. Use flexible
hose to connect the water pipes to the aftercooler and precooler. If the dryer
has an optional flow control, see Appendix D for connection information.

❒❒

Minimum clearance for safe operation and maintenance.

You should maintain 24 in. (61 cm) clearance on at least three sides of the
dryer. If the dryer is mounted with a hopper on a processing machine throat,
clearance between the dryer and hopper can be 4 in. (10.2 cm).

need an adapter. You
can make an adapter
using the dimensions
provided or purchase
one from Conair.

❒❒

A mounting surface that will support the weight of the dryer, support

frame, and a fully-loaded hopper, or just the fully-loaded hopper. See the
specifications tables for weights and volumes.

❒❒

Material and conveying lines installed. If you plan to use vacuum or

compressed air loaders to fill the hopper, install conveying lines to the drying
hopper location.

2 Drill and tap mounting holes or make adapter.

Available discharge assemblies and slide gates fit mounting surfaces with
these bolt patterns and diameters.

Mounting the Dryer and Hopper on
a Processing Machine

WARNING: You are responsible for the structural integrity of this installation.

We recommend that you:

❒❒

Use bolts no smaller than 3/8 inch (M 10) when mounting the

hopper/dryer combination to the throat of a processing machine.

❒❒

Do not mount the hopper/dryer combination on a plate that swings
away or slides away from the processing machine throat. Either
remove the swing or slide plate, position the dryer on the floor, or

mount the dryer to an optional floor stand.

The dryer and hopper mount on a support frame / discharge assembly that bolts to
the throat of the processing machine, as pictured above.

CAUTION: To prevent accident and injury, lift the empty hopper and support frame
onto the throat of the processing machine using a hoist and the lifting lugs provid­ed. After the hopper is mounted, then lift the dryer onto the support frame using a
hoist and the lifting lugs provided.

Tools for installation:

❒ Flathead screwdriver
❒ 9/16” and 1/2” wrench
❒ Hoist

NOTE: You must position the

dryer on the floor or mount it to

an optional floor stand if your

processing machine throat

requires the small discharge

assembly or a mounting plate

with less than a 3 x 3 in.

(7.6 x 7.6 cm) bolt pattern and

Mounting the Dryer and Hopper on
a Processing Machine (continued)

The drying hopper, slide gate, support frame, and discharge assembly may have
been shipped fully assembled. You can remove the hopper from the support frame,
if you find it easier to lift and bolt the frame and then the hopper to the throat of
the processing machine.

1 Lift the hopper, support frame, and discharge assembly onto the process-

ing machine throat. Use a hoist to lift the support frame and hopper. Position
the frame and discharge assembly so that its bolt holes line up with the holes
drilled in the throat. If hole patterns do not match, you can place a mounting
adapter between the throat and the support frame.

2 Bolt the frame and discharge assembly to

the throat. Using four 3/8 in. -16 (M 10)
self-locking bolts, fasten the support frame
and discharge assembly to the throat. The
bolts must be long enough to reach at least
1/2 in. (1.25 cm) into the processing
machine throat or mounting adapter after
passing through the discharge assembly and
support frame.

NOTE: If you removed the hopper from the sup­port frame, lift the hopper onto the frame using
a hoist. Make sure the slide gate is positioned
in the recess on the bottom of the hopper base
plate. Align the bolt holes and fasten the base
plate to the discharge assembly using the four
3/8 in. -16 (M 10) self-locking bolts
provided.

3 Lift the dryer onto the support

frame using a hoist and the lifting
lugs provided. Align the four bolt

holes on the bottom of the dryer
with the four bolt holes on the top
of the support frame. Fasten the
dryer to the frame with 5/16 in. -18
bolts.
