Biofuels, such as wood chips, forest residues, bark, and peat, typically contain high amounts of moisture. Moisture makes biomass expensive to transport, difficult to store and reduces its thermal value.

Haarslev Industries supplies superior drying equipment for the production of pellets and briquettes. Solutions include the disc drier system featuring efficient heat transfer and optionally an integrated waste heat recovery system used for the production of district heating. Disc drier systems can recover up to 80 percent of the energy input.

The absence of air in the drying process secures a non-explosive atmosphere inside the drier and makes this system one of the safest on the market. Finally, our fully enclosed drier technology ensures compliance with ATEX guidelines, minimum downtime and low emission levels when compared to traditional open systems.

 

Disc driers are highly versatile and can process almost all types of biomass. The disc drier system offers superior moisture control of the final product along with easy inspection access and low maintenance costs. The compact design minimises building and installation requirements.
