GEA Niro has 30,000 spray drying test reports from our dedicated drying test centers, and we are equipped to engineer the properties you want into your products as well as the processes needed to produce them.
Spray drying technology
Spray drying is the most widely used industrial process for particle formation and drying. It is well suited for continuous production of dry solids in powder, granulate or agglomerate form from a liquid feed. Spray drying is ideal when the end-product must comply to exact quality standards including properties such as: particle size distribution, residual moisture content, bulk density and particle morphology.
The spray drying process
Spray drying starts with the atomization of a liquid feedstock into a spray of droplets. The droplets are put in contact with hot air in a drying chamber. The sprays (atomization) are produced by either rotary atomizers or spray nozzle atomizers. The evaporation of the liquid from the droplets and formation of dry particles proceed under controlled temperature and airflow conditions. The powder is continuously discharged from the drying chamber and recovered from the exhaust gases using a cyclone or a bag filter.
A spray dryer consists of:
We can assist you with all your spray drying projects, whether you are conducting R&D spray drying, interested in small-scale spray drying, or full an industrial spray drying production facility. We offer powder engineering solutions and proof of concept through laboratory and pilot-plant testing. We also possess an unmatched scale-up experience and global project execution according to your specifications. The GEA Niro spray drying technology center, located at our Columbia, MD (US headquarters), is one of the best of its kind in the world for customer product testing.
