Optimization of coffee bean roasting in a spouted bed roaster was investigated. An air temp. of 250C for 5 min gave the best product, as determined from colour value, total soluble solids, chlorogenic acid content and moisture content. The system was modelled as an unsteady state heat transfer mechanism, and, based on the time-temp. relationship, the overall heat transfer coeff. was 12.023 W/(m2K). It is concluded that the spouted bed roaster gave performance comparable with patented HTST roasters.
