Safety Precautions

ANKOM DryerRD

Caution: Hot Surfaces - Do not touch the cabinet during operation. The surface can exceed
70o C (158o F). Failure to observe this caution may result in injury.

Caution: Hazardous Voltages- Do not operate the instrument with the electrical compartment

open. Hazardous voltages are present during operation. Electrical shock or electrocution may
result if ignored.

WARNING: Using the instruments in a manner not specified by the manufacturer may impair the
protection provided and voids the warranty.

This system is designed to meet and/or exceed the applicable standards of CE, CSA, NRTL and OSHA.

The ANKOMRD Dr yer is designed to remove moisture from ANKOM XT4 or F57 filter bags. Simply
place filter bags in the bag holder with clip-on handle in place and set the holder in the drying chamber.
Attach a filter to the top of the drying chamber and press the power switch which turns on the heat and
fans to dry the samples.

Two types of filters are used with the Dryer

-HCl Dryer Filter #RD2- This filter is used when drying samples after hydrolysis. The filter

neutralizes HCl fumes given off during drying. The filter should be changed when the maroon
bottom filter media of the filter degrades or sags below the filter frame. The effectiveness of the

filter can be checked by placing a small beaker of Ammonium Hydroxide (NH4OH) on top of the
filter while samples are drying. If white vapor is present when drying, the filter is no longer
working. PH paper can also be placed on top of the filter when drying. If the paper turns red (not
orange), replace the filter.

-Dryer Filter #RD1- This filter is used when drying fat or fiber samples. It does not need to be

replaced. It is used to optimize the drying rate of the instrument.

Instrument Set Up and Installation

Requirements:
Tools: Flat blade screwdriver

Power: 100-120V 50-60 Hz (domestic) 220V-240 50-60 Hz (int’l)

The ANKOMRD Dryer should be installed in a vent hood free of dust and excessive moisture.
The ANKOMRD power cord must use a grounded receptacle. Hydrolysis leaves small amounts
of HCl in the filter bags even after rinsing. Drying the hydrolyzed samples in the ANKOMRD
Dryer removes moisture and the remaining HCl (For drying after fiber or crude fat
determinations, a vent hood is not necessary).

1. Plug the power cord into a grounded receptacle.

2. Tighten the Inlet hose clamp with a screwdriver and route to a clean source of air.

Operating Instructions

Sample Drying

Follow the sample drying protocol in each specific procedure. Blotting reduces drying time for
hydrolysis samples. After completion of hydrolysis, the filter bags are blotted on paper towels. Place
the wet samples on four sheets of paper towel. Place two sheets on top of the bags. Uniform pressure
(ANKOM Blotter or similar) is used on top of the paper towels to gently press the water out of the
bags. ANKOM Blotter (part #H35) is foam cushioned and weighs ~10 lbs. After one minute repeat
the blotting process for two minutes prior to placing them into the ANKOMRD Dryer.

1. Remove the filter by lifting up both filter latches and set the filter to the side.

2. Place processed or blotted filter bags into the bag holder. Hydrolyzed samples may use the HCl bag
holder in the ANKOMRD Dryer.

3. Place the bag holder into the ANKOMRD Dryer and attach the filter.

4. Turn on the ANKOM

Dryer. The fans, then the heater, will automatically turn on.

5. Press <set> on the temperature controller and use the Up and DOWN arrows to set the drying
temperature. Push <set> to enter the temperature. Use the temperature listed in the assay method.
(usually 110

o

C)

6. Dry the samples for the required time and turn the instrument off.

7. Remove the filter. Remove the samples and immediately place into a desiccant pouch. Cool to room
temperature and weigh.

Periodic Maintenance

Wipe the outside of the instrument with window cleaner or a damp sponge as necessary. Do
not use Acetone.

Fuse Replacement- Turn off the power and unplug the instrument.

1. Use a screwdriver to twist (counterclockwise) the gray fuse holder. Remove the holder and

replace the fuse.

2. Push in and twist (clockwise) to install the new fuse.

Filter Replacement-

The RD2 HCl filter should be replaced when the maroon bottom filter media of the filter
degrades or sags below the filter frame.

The effectiveness of the filter can be checked by placing a small beaker of Ammonium
Hydroxide (NH

OH) on top of the filter while samples are drying. If white vapor is present

when drying, the filter is no longer working. A strip of pH paper can also be placed on top of
the filter when drying. If the paper turns red (not orange), replace the filter.

Generally, the filter should be replaced every 3-6 months depending on usage.
