GEA 10kg/h ATEX spray drier (atomization drying plant)

COMPLETE GEA SPRAY DRYING PLANT

Evaporation capacity: 10 kg/h – Chamber temperature up to 200°C

Previously used for the atomization of water-based solutions, but ATEX certified (except for the premixer).

The system was designed for the atomization of aqueous and solvent-based solutions (ethanol, methanol, acetone, isopropyl alcohol), but was only used for drying an aqueous solution of a plant extract (not classified as hazardous, toxic, or harmful).

The drying chamber is in excellent condition, free from damage or scratches.

Spray Drying – Process Description (Closed-Cycle Operation)

Spray drying is a method for drying a liquid containing dissolved or suspended solids to obtain a powder product.

Compared to other drying techniques, **spray drying allows very precise control of particle formation**, enabling the production of powders with desired properties such as:

* Density

* Solubility

* Particle size

* Particle size distribution

* Particle morphology

* Taste masking

* Residual solvent content

Note: The plant is supplied "as is", disassembled, without performance guarantees.
