Beschreibung
Zusammenfassung:	The invention relates to a method and an arrangement for precise monitoring and control of torrefaction temperature, which enables accurate control of the quality and properties of the torrefied material. The method includes determining the surface temperature of the biomass in the torrefaction arrangement is using an IR-thermometer and hot nitrogen gas a purge gas.
