Introduction
The document discusses the Allgaier Rolling Bed Dryer WB-T, a technology designed for drying biomass as an alternative fuel. This dryer is part of the growing trend towards using CO2-neutral energy sources to compete with conventional fuels for heat and electricity generation.

Specifications and Concept
The rolling bed dryer is characterized by its simple, effective, and reliable design. It uses a product circulation method where biomass is continuously mixed by paddles, ensuring good heat transfer and even drying. The drying air is supplied through a perforated plate, allowing for the separation of fine materials like dust and sand, enhancing the calorific value of the biomass and reducing ash content.

Applications
The dryer is versatile, suitable for a wide range of biomass types including wood chips, green waste, bark, and animal feed. The high quality of the dried products makes them suitable for direct firing, pelletising, briquetting, and more advanced processes like gasification or torrefaction.

Advantages
The Allgaier rolling bed dryer offers several advantages over conventional dryers such as belt, drum, or fluidised bed dryers. These include trouble-free operation with various grain sizes, universal application, good mixing and even moisture distribution, a cleaning effect for optimal product quality, and the use of residual energy. Its sturdy construction ensures high availability and low maintenance costs.

Trial System
A trial system is available at the Allgaier technology centre for testing specific products, providing a capacity of 1 m³ for realistic testing scenarios.
