Profile Overshoot Early in Roast
Posted: Wed 10 Jan, 2024 4:55 pm
I'm finding some beans tend to overshoot the profile curve early in the roast and I am wondering if it is possible to correct for this. Currently I am doing an Indonesian Blue Bianca with preheat set to 1200 and it still logs below the curve at the start but crosses the curve at about 29s and then overshoots, only getting back to the curve at about 2m 30s.
I am wondering how early in the roast I could introduce a corner and/or a negative Zone boost to reduce the heating faster and get the log tracking closer to the profile. My understanding is that the preheat overrides these adjustments during the early stages, in which case maybe there is nothing I can do to correct it. If I increase the preheat to try and keep the log above the profile it then also overshoots even further.
I have attached a copy of the log to illustrate this.
