Abstract:
The invention relates to a method and a system for efficient torrefaction of a biomass. Said system comprises a first zone for heating of an optionally pre-dried biomass and an insulated second zone for torrefying the heated biomass. The second zone has an inlet being connected to an outlet of the first zone and means for withdrawing torrefied biomass arranged at the bottom of the second zone, such that the biomass can move downwards through the second zone by means of gravity. Means for heating are arranged at the first zone, but not at the second zone.
