Coffee roaster prototype enhances friend’s homebrewing facility.
A friend who passionately experiments with homebrewing and coffee roasting asked me to design a coffee roaster prototype for his experiments.
After online research and multiple visits to a local shop with a Probat roaster, I created a 3D CAD model of my proposed design.
After refining the model, I ordered laser cutting of prototype sheet metal and started machining and fabricating parts myself.
In June we did our first roasting trial. While the very first run produced a minor fire scare due to bean escapes, the second one gave us usable coffee!
We took what we learned and I refined a few things for the second session:
We are generally pleased with how the roaster prototype works. We are currently considering further mechanical refinements to shrink the size, simplify assembly, and reduce the cost of the roaster.
