Method and apparatus for torrefaction of biomass materials

摘要: Exemplary techniques disclosed provide a heat transfer element adapted for use in rotary furnace torrefaction and particle size reduction of biomass material. The is made up rounded object having specific gravity substantially higher than the material to be torrefied, capacity sufficient elements hardness serve as grinding media reduce torrefied. has one or more surface features pre-formed object. are configured increase traction between A system material, including charged with described above, method using such also discussed.
