Key benefits

Reliable quality and uniformity
Get reliable, efficient drying and cooling with high fluid-bed rates and precise control. Motorized paddle conveyors ensure consistent quality by managing retention time and avoiding uneven drying—ideal for specialized, high-value products.
Engineered for energy efficiency
Maximize energy efficiency with pulsed air fluidization, reducing power use without compromising performance. The OTW design includes full air and energy recovery systems, providing further efficiencies tailored to specific plant locations and products.
Food grade performance and hygienic design
Optimize drying with precise process control to prevent thermal degradation and microbial growth. Built-in hygienic design allows for easy cleaning and maintenance, ensuring maximum throughput and food safety.

Precise air fluidization​

Uniform air distribution for optimal drying

Air pressurizes the dryer below the perforated plate, ensuring uniformity across the full bed. The unique aligned hole pattern ensures that high velocity air fluidizes the product and directs it downstream.

Advanced process control​

Real-time monitoring and management

Continuous sensing and feedback loops, coupled with cloud-based analytics can boost process and mechanical operation. Precise drying time, as a critical control point, provides a step change in online recipe management.

Optimized heat and air infrastructure

Tailored air systems for enhanced efficiency

Complete air systems with fans, steam or electric burners, and controls optimize the OTW for specific plant locations and products. Energy recovery systems provide further efficiencies.

Advanced air pulsation

Effective product intermixing and clump elimination

Adjustable rotating valve meters air into the pressure chambers. This rapid pulsation of high to low velocity lofts the product and ensures intermixing, eliminating clumps.

Efficient paddle conveyor

Consistent bed movement for invariable drying

An adjustable driven paddle conveyor constantly pushes the expanded product bed forward. This positive sweep ensures a fixed controllable retention time, eliminating inconsistent drying and allowing processing of difficult materials.

​​Intuitive localized control​

Accessible and immediate process parameter adjustment

Individual dryer control is provided with an intuitive localized interface. Immediate visibility and access to key process parameters. Can be integrated into your entire plant's operation using Bühler's systems.
