Home > Products > GA22

Processing Capacity

50g to 300g

Operating Temperature Range

40°C to 200°C

Liquid Sample Flux

up to 28 ml/min.

Spraying Nozzle

for Liquid and Air

A system to granulate powder of small amount and to dry moist powder.

The GA22 uses a fluid bed and it can be used to granulate powders or to dry moist powders.
It is capable of processing samples of between 50g and 300g and well suited for expensive samples and laboratory experiments.

The setting of testing conditions is easily entered from the operation panel.
The testing mode can be easily observed as the chamber is made of superhard glass.
Since it is equipped with impellers, consistently good fluid conditions are obtained.

Control panel
GA22 Control Panel

Inlet temperature, outlet temperature and drying air volume are displayed digitally. Condition setting dials and stage level control switch are located on the front panel for easy use.

GA22

Since a small quantity of samples from 50g to 300g can be treated this device is most appropriate for the treatment of expensive samples and the experiments at the laboratory level.

Easy operation and maintenance

A stirring blade is attached to the perforated plate so that inferior fluid condition can be improved and wet powdered matters drying can be processed by stirring.

The stage level control switch are located on the front panel for easy use.
Cleaning of chamber is also made very easy.
