Spray drying solution for heat-sensitive products
Optimize the drying of heat-sensitive and challenging materials into high-quality, agglomerated powders with a system that minimizes waste and enhances productivity.

Transforms Heat-Sensitive Liquids into Agglomerated Powders
The FILTERMAT® Spray Dryer by GEA is engineered specifically for challenging applications where traditional drying methods fall short, effectively handling heat-sensitive and sticky products. This spray dryer utilizes a perforated filter belt to gently deposit and convey product through controlled drying zones, transforming liquids into agglomerated powders with minimized lumping and deposit formation. Ideal uses include processing whey protein isolate, non-dairy creamers, fruit powders, and more. The design supports continuous operation, with a compact disperser flow straightener and double-feed nozzle system enabling 24/7 production while allowing feedline CIP during operation. Operating at reduced temperatures, it preserves the integrity and quality of sensitive products, while the GEA AddCool heat pump technology significantly lowers energy demand. Available in stainless steel for enhanced corrosion resistance, the FILTERMAT® offers options for retrofitting into existing facilities and testing at GEA’s Soeborg Center of Competence or on-site with pilot plant equipment.
