Overcoming the Challenges of Spray Drying in Dairy Processing

Don’t Struggle to Meet Production Targets
Dairy processors often face low production rates and underperforming dryers due to inefficient or incorrect nozzle setups. The SprayDry® nozzle product line offers the broadest range of designs in the industry, each specifically engineered to meet the demands of dairy applications. Selecting the right nozzle design and operating parameters is essential for maintaining peak dryer performance. From swirl chamber nozzles that improve free passage, to slotted core nozzles for finer droplets, to multi-orifice nozzles that boost production without requiring additional capital investment, we have a tailored solution to keep your operations running smoothly.

Stop Product Loss and Improve Yield
Powder loss to dryer walls or the baghouse is a common issue in dairy powder production. Poor atomization or incorrect nozzle sizing can leave particles under-dried or over-dried, leading to waste and quality concerns. SprayDry® engineers work with your team to optimize spray angle, droplet size, and flowrate, ensuring powder stays airborne and dries efficiently, improving both yield and quality.

Achieve Specific Bulk Density Requirements
Out-of-spec and inconsistent bulk density can disrupt downstream processes like packaging and reconstitution. SprayDry® nozzles give you control over droplet size, and therefore particle size and bulk density, through optimized nozzle design and operating parameters. Generate larger, denser particles with the SV nozzle, or finer particles with the SB or SK series, to meet tight spec requirements. Achieving the proper bulk density results in high product quality, efficient packaging, smooth processing, and cost-effective operations.

Reduce Bearding and Fire Risk in Dairy Plants
Bearding and product buildup around the nozzle can introduce serious safety risks, especially with dairy ingredients that are prone to caramelization or ignition. Our anti-bearding nozzles, designed with different geometries, are optimized to resist buildup and minimize this risk. Proper nozzle selection and placement also reduce cleaning frequency and enhance overall plant safety.

Combat Clogging and Rapid Wear in High-Solids Formulas
High fat and protein content in dairy products often leads to nozzle clogging, CIP challenges, and costly wear. SprayDry™ nozzles are engineered with Maximum Free Passage technology to reduce blockages and improve spray consistency. Our tungsten carbide wear components, available in multiple grades, are proven to withstand the high pressures and abrasive characteristics of dairy feedstocks, helping you cut downtime and extend service life.
