A bench
top unit for the rapid drying of chemicals, foodstuffs and minerals
prior to sieve analysis and other tests.
The FBD 2000 is a compact, portable dryer. It's powerful
air delivery system makes drying a very fast operation. The fluidisation
mixes and separates the particles minimising the risk of 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 an 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 of air flow
from the base of the 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 2kW electric heater and can be
set to any temperature up to 200°C. The temperature is controlled
by a closed loop system that can achieve stability to within 1°C.
Timed Cycle
A built in 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 from 0.4 to 2.4 m/min volume (0.9 to 5 m/sec speed). Optimum
levels can be set by observing the sample behaviour within the glass
tubs.
Filter Bag Material
Filter bags are usually nylon or terylene with other
materials available to suit more aggressive conditions such as sustained
high temperature drying.
Fast - drying times range from a few seconds to minutes
Efficient - higher rates of heat transfer ensure faster and more homogenous
drying than oven, microwave or vacuum drying.
Versatile- suitable for most granular and powdered materials
Reproducible
results - precise controls ensure uniform and reproducible results
Easy to use - manageable controls with straightforward settings
