Performance evaluation of drying of maize in an in-bin counterflow system using biomass energy Academic Article uri icon


  • Approximately 140 t of wet maize was dried during the testing of the concentric vortex-cell furnace/in-bin counterflow drying system. The results demonstrate that the CVCF biomass is a technically viable alternative to conventional fossil fuels. The drying capacity of the CVCF/IBCF system is 90% of the LP fueled system. The CVCF/IBCF system operates at about 70% efficiency in converting biomass into energy for grain drying. A CVCF simulation model was used to analyze the effect of different operating conditions. Ambient temperature, feed moisture and excess air are factors which most affect the system efficiency.
