Abstract

A fluidized bed drying integrated with biomass furnace was tested for drying of paddy. The drying of 12 kg of paddy via this drying system reduced the moisture content from 23% (wet basis) to 14% (wet basis) in 1338s and 1007s with average temperature of 60°C and 70°C, respectively. The drying rate varies from 0.15 to 0.48 kg every 300s and 0.2 to 0.5 kg every 300s with the average of 0.27 and 0.335 kg every 300s for average air temperature drying of 60 and 70°C respectively. For temperature of 60°C obtained SMER maximum, minimum and average, respectively: 0.72 kg/kWh, 0.23 kg/kWh and 0.37 kg/kWh. For temperature of 70°C obtained SMER maximum, minimum and average, respectively: 0.66 kg/kWh, 0.26 kg/kWh and 0.38 kg/kWh. The thermal efficiency varies from 14.78 to 47.31% and 17 to 42.49% with the average of 24.31 and 24.93% for average air temperature drying of 60°C and 70°C respectively.
