Continuous spray dryer for thermosensitive products
Ideal for processing thermosensitive slurries, this spray dryer ensures precise moisture control and fine particle encapsulation, making it crucial for achieving high-quality powder output in your production line.

Atomizes and Dries Slurries into Fine Powders
The RINA Spray Dryer from Riera Nadeu offers a sophisticated solution for transforming pumpable, thermosensitive slurries into fine powders through continuous atomization and drying. This system is ideal for applications in pharmaceuticals, biotech, chemicals, food processing, and more, tackling the unique challenges of encapsulation and particle refinement. It operates by atomizing slurries in a vertical tower, where precise nozzle configuration and controlled hot air flow ensure consistent drying. With customizable configurations, it accommodates various particle sizes and drying requirements, optimizing throughput and product quality.
Processing capacities vary across models, with evaporation rates ranging from 28 to 700 kg/h of water, enabling high-volume operations. The system excels in demanding environments, offering material options like Hastelloy for chemical resistance and compliance with OEB4 standards for handling toxic substances. Safety is enhanced with explosion-proof certifications and the possibility of operating in a closed-loop with nitrogen gas.
Automation is a key feature, incorporating PLC controls for seamless integration and efficient remote monitoring. Cleaning is simplified with an automatic CIP system, ensuring minimal downtime and preventing cross-contamination. Riera Nadeu offers tailored engineering support to match specific production requirements and plant layouts, making it a versatile asset for diverse industrial sectors.
