Hey, has anyone faced an issue before where the IBTS behaved weirdly mid roast and then went back to normal again. I roasted 3 back to back roasts today, and on my last one between minute 2 & 5 IBTS RoR was very volatile, yet the temp was increasing steadily and very similar to the roast right before it. I would like to think it’s just a calculation issue from the software but I’d like to know what you guys think, and if anyone has faced a similar situation.
Looks pretty much ‘normal’ to my eye-
Be aware that IBTS RoR from an R1 is derived from data from the roaster f/w (dunno how it’s processed on an R2). The R1 has limited ability to smooth RoR as it must be done in the f/w which also manages the roast & the roaster.
Also, my Bean Temp probe was replaced a few years ago and was not re-calibrated after the new probe was installed. Hence BT on my roaster doesn’t reach IBTS temp at the end of the roast (an offset error) as it should. Your BT/IBTS properly display about the same value at End of Roast.
