The Atlas-Stord Rotadisc(r) drier is an alternative to the direct fired drum drier. The Rotadisc(r) drier is an indirect steam heated contact drier. The steam supply pressure can be between 2 - 10 bar. As a contact drier no fluid is used as carrier for the heat transfer and thus the vapours are almost pure water vapour with a high wet bulb temperature. By condensing of the vapours a recovery of up to 80% of the steam energy input can be recovered for district heating. Learn more at World Bioenergy 2008, stand A00:61.
