Biomass drying solution
Achieve efficient and gentle biomass drying with innovative heat exchange technology, ensuring optimal moisture control and quality preservation for diverse organic materials.

Dries and Mixes Biomass for Efficient Processing
The Rolling Bed Dryer WB-T from Allgaier Process Technology is engineered to enhance the drying process of biomass materials. By combining the principles of drum and fluidized bed dryers, it provides gentle, low-temperature drying with an extended residence time, ideal for diverse biomass applications. This equipment excels in processing wood chips, green waste, and digestate, yielding products like pellet fuel and compost.
Operating continuously, the WB-T features a unique design where the product layer rests on a perforated plate, allowing drying air to be circulated from below. An integrated agitator ensures thorough mixing and transport of materials, facilitating efficient heat exchange and preventing moisture pockets. Capable of utilizing residual energy, it significantly reduces process costs and maximizes waste heat recovery.
Constructed for durability, the WB-T is available in explosion-proof versions, enhancing safety and suitability for various environments. Its robust build leads to high availability and minimal maintenance. With the ability to handle various particle sizes, it demonstrates versatility in waste and recycling industries. Options for customization and engineering support ensure that the WB-T integrates seamlessly into your existing production line, optimizing performance and production outcomes.
