Dingli Biomass Pellets Torrefaction Machine is developed to convert densified “white” biomass pellets into “black” torrefied pellets. The complete torrefaction plant is designed and built by our company, while the torrefaction reactor and the process adopt the patented technology from our strategic partner. The technology provides the opportunity to torrefy “white” biomass pellets directly with minimal dust and small particles, thus safeguarding the quality of torrefied “black” pellets to meet international standard, while optimizing the overall energy consumption of the complete plant.
We have a design and research team that leverages the newest technologies to bring compact and highly convenient solutions to a wide range of users.
Our unique design and compact torrefied pellet machine can help you torrefy your white biomass pellets without causing significant pollution. This makes our machines eco-friendly and meets the global standards in terms of pellets and machine quality. Our machines also consume comparatively low energy.
Superior Performance of Torrefied Wood PelletsWith a higher energy density, less water content, pure composition, torrefied wood pellet has a lot of advantagescomparing with wood pellets and even coal.
Biomass pellets are solid biomass fuels obtained by crushing, drying, and pressing wood chips, crop straw, fruit shells, palm waste, and other materials. Due to their regular shape, uniform size, and high density, they are easier to transport and feed continuously compared to loose biomass, and are also suitable for continuous pyrolysis and carbonization production. Raw materials with high moisture content need to be dried first. The drying system removes free water in the material to ensure that the moisture is controlled within 8‑12%, which avoids cracking and poor molding during subsequent carbonization and briquetting processing. Raw materials are heated in a carbonization furnace under oxygen‑limited conditions. The organic matter undergoes pyrolysis, removing volatile components, and finally forming solid biomass charcoal. The carbonization temperature and holding time directly affect the quality of finished charcoal. After carbonization, the biomass is converted into high-quality biochar or charcoal. The finished product can be used for soil improvement, biomass carbon fertilizer, carbon sequestration, industrial fuel, BBQ charcoal, shisha charcoal, or as a raw material for activated carbon production, depending on the original biomass and processing conditions.
