B. Rohowsky, J. Witzelsperger, E. Remmele & M. Faulstich
In field trials sweet sorghum variety “Keller” was cultivated to investigate how the chopped biomass can be stored to provide an efficient and quality-conserving low-loss supply of mass and sugar yield for ethanol purposes. For this reason sweet sorghum was harvested with a common self-propelled-forage-chopper and transported by a farm trailer. In pilot plant scale two different particle sizes (length 10 mm and 20 mm) and two different loadings of 0.5 % (FM) and 1.0...
