Recommendable torrefaction conditions were specified on the grounds of GT and DTA curves for the specimen of crushed stems of Yacon and Jerusalem artichoke. The impact of the size of crushed stems particle on the torrefaction process was monitored. The stem crushing proces was optimized based on the results. We tested the effect of torrefaction performed on pellets made of raw material and wood chips, of which the pellets were made aftewards. It has been unambiguously proven that it was sensible to pelletize torrefied chips, otherwise the pellets were losing their coherence and crumbled. We calculated the fuel calorific value and its dependence on the residence time in the reactor. The economic benefit of torrefaction ih that the power necessary for evaporation and leaching artichoke cutting in water is obtained by combusting torrefied crushed stems.
