Chemical products vary in their chemical formulation, nature of the product
to be dried and in the requirements for the end product. GEA Niro has
significant expertise within the spray drying of chemical products. When selecting a spray drying plant
configuration, it is important to know the requirements for the end product. Is
the goal a regular bulk product, or is it a specialty chemical that should be
agglomerated, granulated and dustless?
The feed material for chemical products varies significantly due to
differences in chemical composition - paste, slurry, suspension or solution. Is
it dissolvable in water or an organic solvent? GEA Niro has developed a series
of spray drying plants that can cope with all of the above.
Your product and your requirements for final powder properties determine which type of spray dryer you
should select. GEA Niro's range of spray dryers spans from conventional spray dryers to very
sophisticated types. For all, we ensure that you will get sufficient production
flexibility to meet your customers’ requirements for residual moisture content,
powder structure, bulk density, and other powder properties. GEA Niro´s product
specialists will help you determine the right solution, and GEA Niro’s test facilities are
available for conducting feasibility tests and developing the optimum spray
drying process for your needs.

The spray drying process
The spray drying process
depends entirely on the composition of the product. Some are very easy and
others very difficult to dry. A GEA Niro spray dryer is designed to ensure:
- Best product quality with properties as put forward by the end-user
- Low energy consumption
- Protection of the environment
- Long operation time
- Comply with the strictest requirements for health, safety and environmental
compliance
- Fulfill EU
Directives
To support our design engineers when they select the drying parameters, and
thereby the size of the spray dryer, we use the DRYNETICS™ single particle drying method developed by GEA
Niro.
