Spray Dryer
GA32 |
 |
 |
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.
