Slow Light Roasts
Posted: Sun 04 Jun, 2023 10:33 am
It’s been challenging for me to do slow light roasts on the KL. Is it just me, but every bean seems to roast very quickly.
Let’s start with the elevation Rest profiles. Even with high elevation beans, I find that I need to use low elevation profiles, and they can still be on the fast side (FC @ ~5:00.) I’ve also tried Raost and Adaptive Raost as starting points.
Additionally, I will sometimes get a shutdown due to excessive ROR on the same bean and same profile on different roasts. Looking at the logs, the temp wasn’t excessive. It was just playing catch-up.
On other roasts, I sometimes get a shutdown with the heating too slow error. I hate that! I’m shooting for a slower roast! Keep going!
I’ve been using 1/4 batches (113g.)
BTW, with the faster roasts, I get non-uniform results where the overall roast is medium, but some beans are oily after a few days.
I’m coming from a Behmor, which tends to lack power and isn’t able to do very dark roasts, unless the batch size is small.
Any guidance for doing slower, lighter roasts is appreciated. Also, are there settings that I can apply to make the machine more tolerant of low or high ROR?
Finally, are there calibrations I need to do? There was a link to calibration instructions in one of the threads, but it’s a dead link. I’ve looked at the manual and couldn’t find it. My machine is a 120V model and was shipped with the new chaff collector. Where do I look for the fan calibration? FWIW I’m at 2,000 ft elevation, if that makes any difference.
The machine has a lot of potential, but I’m a bit frustrated by the software right now. Too many failed roasts.
