How do you like the readings so far? -Scott
I never did figure out why the ET readings from inside the sink drain pipe were so low (around 350F at end of 12-16 min full city roast). However, this BMT probe, located inside the RC read 400F when first crack started 10 minures into the roast. Yellow-tan (see above photo) at 374F is either a mistake in my recording or my early ROR too a bit steep. Next time I'll set the camera to record both the beans and the temperature, and have it fire every minute or do a video..
On my electric fired fluidbed if I move my ET thermocouple even slightly I can end up in an area with a much lower temperature compared to areas directly above the coils which will be a much higher than average temp. I had to find a sweet spot in between the two extremes to end up with a usable reading. It's hard to get a good number without having a large mixing zone between element and RC.
If possible, shoot us a time/BT profile of the roast.
