Solar thermal coffee roaster
Home coffee roasting is a growing hobby for coffee lovers. It is a challenging but enjoyable process and can eventually result in tasty, flavourful and aromatic roasted beans.
However, it requires a high level of skill to manually roast coffee, and automatic roasters consume a large amount of energy.
To reduce energy consumption and complexity for beginners, the aim of this project was to design, build and test a small-scale automatic solar thermal coffee roaster. The prototype of this project has been built, which integrated the roasting chamber, cyclone separator, heating system and blower to present a closed loop system. The roasting chamber has been tested and is a verified fluidised roasting chamber. The cyclone separator has also been tested and proved its capability to collect solid particles generated during roasting.
Overall, this project provides an understanding of how a closed loop system can be applied for solar thermal coffee roasting.
