roast 003 brazillian

Don’t know what sort of programming the iRoast has, but it seems stupid. Note the graph above which shows actual temperature versus the programmed temperature curve. Roast 2 was a hotter profile, yet it managed to be less hot than the Roast 3. Everything else (ambient temperature, beans, weight)
It’s like this thing overshoots but has no satisfactory way to cool or vent itself, so it just keeps overrunning the temperature guidance. We’ll see how the beans are tomorrow morning, but I can’t imagine they are materially different from roast 002. The first crack perhaps came 30 seconds later, but not much, and I still couldn’t get a more extended roast. Ugh.

Am cooling the iroast in front of a fan, and in an hour or so, I’m just going to run it at 160C (the lowest available temperature) for 15 minutes and see what this thing does.
