Hi, I recently started roasting on a MCR 6kg. I came from a fluid bed roaster so I have lots to learn. During my last roasting day I noticed large drops in IT (over 60 F) which in turn dropped my ET and thus my RoR, with over a minute to recover. Around minute 5 on this roast, also happens on the reference roast. My gas, air, and drum speed where all kept the same through this drop. Also why does the ET RoR suddenly stop recording? Thanks for any ideas!
