Abstract

Language:

The roasting coffee is one of the processing coffee beans which determines the quality of the coffee flavor. In general, the process of roasting coffee uses a rotating cylinder, a fixed drum with agitator and a fluidized bed. Theoretical study of fluidization and heat transfer has been carried out on a fluidized bed coffee roaster 1000 gram capacity with a tubular roasting chamber. Green beans (Robusta coffee) used in the roaster at two different operating temperature settings, 250°C and 220°C for high-temperature short time (HTST) and low-temperature long time (LTLT) roasting processes. At this operating temperature, minimum fluidizing velocity was 2.19 m/s and 2.16 m/s respectively, and the thermal energy for roasting coffee was 8773.25 W and 7639.56 W respectively. The thermal energy was defined based on the heat transfer from hot air to coffee beans which was 3399.63 W for HTST process and 3091.49 W for LTLT process that calculates at hot air velocities 2.5 m/s.
