DMR Flash Dryer: Over 70 Years of Innovation
Flash drying revolutionised industrial drying processes by enabling the rapid and energy-efficient drying of fine materials using a hot air stream. In the early 1950s, Hosokawa Micron developed its first industrial flash dryer, specifically designed for the chemical and mineral industries.
Today, Hosokawa Micron continues to lead innovation in flash drying technology with the DMR flash dryer: a cutting-edge solution that combines drying, milling, and classifying into a single, compact and continuous process step. Moisture is evaporated within seconds, larger particles are milled and de-agglomerated during drying, and fine particles are classified to ensure a consistent, high-quality end product.
The DMR flash dryer handles a wide range of feed materials, including viscous slurries, pastes, wet filter cakes, and fine powders with high moisture content. It is ideally suited for industries such as minerals and mining (processing materials like bentonite, kaolin, and gypsum), chemicals (pigments, catalysts, polymers), energy storage (battery materials), and agriculture (animal feed additives).
A Smart Alternative to Traditional Dryers
Unlike conventional spray dryers, the DMR flash dryer can directly process mechanically dewatered products without the need for rehydration. This advantage results in lower energy consumption, a smaller equipment footprint, reduced operational and maintenance costs, and the ability to process highly viscous or sticky materials. As a result, the DMR flash dryer offers a more sustainable and cost-effective drying solution compared to traditional technologies.
Key benefits include:
✅ Extremely short drying times
✅ Consistent, high-quality end products
✅ Energy savings through efficient heat utilisation
✅ A compact design that easily integrates into existing production lines
✅ Suitability for a wide range of products, including fine powders, slurries and heat-sensitive materials
Testing & Process Development
At their Test Centre in the Netherlands, Hosokawa Micron offers pilot-scale testing with the DMR flash dryer. Customers can conduct process trials, determine drying curves, analyse material behavior, and optimise their drying processes before full-scale implementation. Testing is available from laboratory to production-scale setups and is fully supported by experienced process engineers.
Based on these trials, Hosokawa Micron delivers complete, fully integrated flash drying systems, tailored to each customer’s specific requirements. These systems include the DMR flash dryer, together with all necessary feeding, filtration, collection, and intelligent control technologies.
