Has anyone some experience with the 10 kg roaster from jafinox? I started to roast nibs with it, because to reach the temperature of the beans it needs until 1h
Where are you located? I may be able to connect with some colleagues in Brazil who can help answer this.
I do have some experience with the larger roaster and, because they are electric, they are slower than other kinds because of the design.
In general, I would recommend doing a very quick roast to puff the shells then crack and winnow and then roasting nibs.
