Industrial roto-flash dryer for chemical applications
In the chemical industry, transforming cakes, pastes, fluids, and powders into fine, uniform powders can be challenging. Ensuring consistent particle size distribution and moisture content is critical for various downstream processes, and this is where a specialized drying system proves invaluable.
Ensures uniform particle size and moisture content
The Roto-Flash dryer by Dedert is an advanced agitated flash dryer designed for the chemical industry. It produces fine powder directly from the feed material without the need for premixing. With an air residence time of just a few seconds, the dryer is both investment and cost-effective. It accepts various feed types, including cakes, pastes, fluids, and powders, and delivers a uniform particle size and moisture content. The dryer features a compact single-pass design, eliminating the need for external back-mixing or product reintroduction. The integrated internal feed agitation ensures gentle mechanical dispersion, while inlet temperatures can reach up to 750°C. The system is particularly suited for materials like silica, organic or inorganic pigments, and titanium dioxide. The drying chamber is a vertical cylinder with an annular air inlet and an axially mounted rotor, creating a whirling gas flow for efficient drying. Feed material is processed in a controlled manner using load cells and a low-speed agitator that breaks up cakes to a uniform consistency.
