Document Type and Number:
WIPO Patent Application WO/2009/124286
Kind Code:
A8
Abstract:
The present invention provides an autothermal torrefaction device, which can be either stationary of mobile. Embodiments of the present invention include a torrefaction chamber having a chamber inlet for receiving biomass and at least one chamber outlet. The torrefaction chamber can be substantially surrounded by an exterior housing defining an outer jacket and having a jacket inlet and a jacket outlet. The outer jacket and torrefaction chamber define a space therebetween such that a burner unit including an inlet operatively connected to the chamber outlet and an outlet operatively connected to the jacket inlet allows vapors produced or released from within the torrefaction chamber to travel into the burner unit for combustion of at least a portion of the vapors and subsequently travel through the space between the jacket and the torrefaction chamber to provide heat necessary for autothermal torrefaction of biomass.
