Flash dryer for surface moisture removal in powders

Optimize moisture removal in heat-sensitive materials with rapid, uniform drying, ensuring your end-products maintain consistent quality and particle size distribution.

Removes Surface Moisture from Powders and Slurries

Dedert’s Flash Dryer system is engineered to streamline your moisture removal process for powders, slurries, and cakes. Its pneumatic drying and air conveying mechanism ensures rapid and uniform drying, making it essential for industries like plant-based proteins and biofuels. Operating continuously with high-speed efficiency, the flash dryer is capable of handling diverse applications, from corn starch to biodiesel production.

The system offers versatile temperature profiles and feed conditioning options, allowing integration with upstream processes like evaporators or crystallizers for comprehensive plant operations. Utilizing an Open-Circuit configuration, the flash dryer uses ambient fresh air to maintain product purity without contamination risks. For enhanced energy efficiency, Dedert offers a Partial Gas Recycle configuration, recycling most exhaust gases and integrating with a Gas Heated Evaporator for energy recovery, reducing overall operational costs.

Constructed with durable materials suitable for various industrial environments, the flash dryer’s design supports rigorous cleaning and maintenance protocols, ensuring high performance and longevity. Moreover, Dedert provides customization options and engineering support tailored to specific production needs, allowing seamless adaptation to existing production lines.
