Spray Dryers & Flash Dryers

Riera Nadeu has built spray dryers and flash dryers that help industries handle complex drying needs with speed and precision.

Our spray dryer machines turn liquids into consistent powders, making them a trusted choice in pharmaceuticals, food powders, specialty chemicals, and biotech. For high-moisture or bulk solids, our flash dryers deliver fast, energy-efficient drying.

Whether you need a laboratory spray dryer, a large-scale industrial spray dryer, or a fully automated flash dryer system, we provide equipment built for reliability and performance.

Jet Milling & Powder Processing

The RINA Jet Mill micronizers deliver ultra-fine powder processing with precise particle size control, producing particles smaller than 10 µm for pharmaceutical, chemical, and industrial applications such as pigmentation, coloration, and inhalation powders.

Air jet milling ensures contamination-free processing, while the modular, compact design with no moving parts makes cleaning and maintenance simple. These systems can also combine micronization and particle coating for specialized applications.

For abrasive materials, the equipment can be lined with high-alumina, silicon carbide, or tungsten carbide, and safety configurations allow operation in explosive environments or closed-loop nitrogen circuits.
