Paddle dryer for industrial sludge
Achieve consistent drying and pasteurization of complex materials with this advanced paddle dryer, designed for thorough heat transfer and hygienic treatment, ensuring your production line maintains optimal quality and efficiency.
Processes Sludge and Biomass with Efficient Heat Transfer
The ANDRITZ Gouda Paddle Dryer is engineered for maximum efficiency in drying applications, particularly suitable for sludge and biomass processing. Featuring rotating heated paddle shafts in a heated trough, this equipment ensures exceptional heat transfer and uniform product quality by maintaining consistent temperature control without back-mixing. Its specialized paddle design enables hygienic treatment and pasteurization, handling materials such as industrial and municipal sludge, polymers, gypsum, and more. Capable of drying products to specific moisture levels, it aids in producing biosolids pellets, fertilizer granules, and other end-products. Designed for continuous operation, this paddle dryer includes a vacuum option allowing for low-temperature processing, optimizing energy consumption. Constructed with corrosion-resistant materials, it stands up to high temperatures and heavy-duty use, certified by ASME, TÜV, and other international standards. With automatic integration possibilities, the unit offers a clean operation that aligns with environmental compliance and operational safety.
