Downdraft dryer for biomass drying

Quickly reduce moisture content and energy consumption with a versatile dryer that relocates to your harvest site, efficiently processing biomass into biofuel, wood pellets, and more.

Dries and Cools Biomass Efficiently On-Site

The Modular Relocatable Advanced Downdraft Dryer from Forest Concepts is engineered for mobile biomass processing, catering to a diverse range of industries, including renewable energy and agriculture. This dryer features a multi-zone downdraft system with six drying stages and one cooling stage, efficiently removing up to 900 pounds of water per hour from woody and herbaceous biomass. Applications include producing wood chips, pellets, dried grass, and biochar. Mounted on a USDOT-compliant 48-ft flatbed trailer, it offers remarkable flexibility, allowing relocation and rapid assembly/disassembly on-site.

The PLC-controlled “Intelligent Controls” touchscreen interface enhances automation, while custom configurations support project-specific requirements. Operating with 6.5 million BTU/hr of heat capacity, this dryer utilizes propane and operates on a 460V, 3-phase power supply, ensuring high efficiency in continuous production. Its design emphasizes user-friendly operation and minimal environmental impact, featuring energy-efficiency measures that optimize consumption.
