Industrial roto-flash dryer for chemical applications
Achieve uniform moisture and particle size in demanding drying processes with minimal setup, efficiently handling varied input forms such as cakes and pastes.
Efficiently Dries and Agitates Diverse Materials
The Roto-Flash Dryer from Dedert is an agitated flash dryer engineered for precise moisture removal across various industrial processes. This dryer stands out with its compact single-pass design and internal feed agitation, eliminating the need for external back-mixing. Operating with inlet temperatures up to 750°C, it ensures efficient and rapid drying within a few seconds. Primarily used in the chemical industry, it efficiently processes materials like silica, pigments, and titanium dioxide, and extends applications to food ingredients and biofuels, producing end-products such as silica gel and xanthan gum. Handling capacities accommodate cakes, pastes, fluids, and powders, with consistent particle size and moisture content delivery. Integration is seamless with continuous operation, automated control, and adaptability to process conditions. Energy efficiency is achieved through a tangential air inlet and rotor action for uniform gas flow, while construction options ensure durability and resistance to corrosion. Dedert provides customization and support to tailor this equipment for specific production requirements.
