10 Phases of Torrefied Pellets Production

A.  Pre-torrefaction reactions

  1. Fractionation to size (if required)
  2. Conventional pre-drying of feedstock

B. Inside torrefaction reactor (inert condition)

  1. Evaporation of residual moisture
  2. Heating of feedstock up to +100oC
  3. De-polymerization of hemi-cellulose

C. Post-torrefaction reactions (inert condition)

  1. Cooling and re-polymerization
  2. Crushing to size
  3. Conditioning
  4. Densification to pellets

D. Post-conditioning

10.  Cooling and dust removal
