Continuous granulation dryer for chemical and polysaccharide applications
Drying substances with problematic flow characteristics and varying consistency often requires a system capable of gentle treatment while ensuring consistent product quality. Industries such as chemicals and polysaccharides face these challenges regularly.
Dry and granulate continuously with low temperatures
The Druvatherm® granulation dryer from Gebrüder Lödige Maschinenbau GmbH combines convection and contact drying for a continuous operation. This dryer is designed to handle substances that exhibit problematic flow characteristics and changing consistencies. The dryer adapts retention time to the specific process, ensuring gentle product treatment at low temperatures. Utilizing Lödige’s fluid bed principle, it creates an intense mixing effect that separates particles and enhances heat exchange through the heated drum walls. If desired, high-speed choppers can control product retention times, allowing for defined grain size distribution. Suitable for both contact drying under normal pressure or in an inert atmosphere, it uses thermal energy applied through jacket surfaces and high-temperature gases. This versatile system is ideal for the chemical industry and polysaccharide production.
