- Fast - Drying times range from a few seconds to minutes.
- Efficient - High rates of heat transfer ensure faster and more
homogeneous
drying than oven, microwave or vacuum drying.
- Versatile - Suitable for most granular and powder
materials.
- Reproducible results - Precise controls ensure uniform and
reproducible results.
- Easy to use - Manageable controls with straightforward settings
gases to escape.
The FBD 2000 is a compact, portable dryer. Its powerful
air delivery system makes drying a very fast operation. The
fluidisation mixes and separates the particles minimising the
riskof abrasion and the creation of lumps resulting in a truly
representative sample. The comprehensive set of controls makes it
ideal for use in the laboratory on a wide selection of
materials.
High air flow rates provide high rates of heat transfer and
ensure much faster and more homogeneous drying than other methods
such as oven, microwave and vacuum drying. drying times range from
a few seconds to minutes. Complete drying is usually achieved in
under 15 minutes.
How the FBD 2000 operates
A powerful fan delivers the high volume air flow from the
base unit into a special tub assembly which holds the sample
material.The flow of heated air passes through a diffuser gauze
which supports the bed and evenly distributes the air as it passes
into the tub.
A filter bag at the top of the tub keeps the sample in while
allowing the air, moisture and gases to escape.
TEMPERATURE CONTROL - Air is heated by a 2kWelectric
heater and can be set to any temperature to to 200°C.
TIMED CYCLE - A built in digital timer enables the drying
time to be pre-set and the drying operation to be carried out
unattended. At the end of the cycle time an alarm sounds and
the unit switches off automatically.
AIR FLOW - The air flow rate and fluidisation velocity
are infinitely variable from0.4 to 2.4 m/min volume (0.9 to 5m/sec
speed). Optimum levels can be set by observing the sample behaviour
with the glass tubs.
FILTER BAG MATERIAL - Filter bags are usually nylon or
terylene with other materials available for more aggressive
conditions such as sustained high temperature drying.
ACCESSORIES - 
Single tubs come
in 2 and 5 litre sizes in either stainless steel or glass. A
multi-tub unit with 4 x 300 ml tubs is also available for
drying four samples simultaneously. Glass tubs are particularly
useful for observing the fluidisation process to establish optimum
settings.
An attachment is also available for the efficient drying of test
sieves.
