Spraying Nozzle

for Liquid and Air

A small sized dryer for laboratory use which produces uniformalized fine particles.

The GA32 is a compact spray dryer using a spray dry method which enables simple use for laboratory experiments. It can be used for a wide variety of drying operations, from preliminary examinations for pilot plants to drying operation in general laboratories.

No danger of damaging foodstuffs, medical products and products that are sensitive to biochemical-heat.
No oxidation takes place and the water content of the formed powders is low, so that there is no contamination.
Even a solid body of ca.0.5g can be dried.

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.

ADL Control panel

In this Spray Dryer, the sample are dried and transformed into a uniform fine powder of amorphous form, so both its solubility and reactivity are extremely high in comparison to crystal.
