So I finally assembled my Turbo Crazy and tried roasting today. Here are the results - http://imgur.com/a/gcYN6 I don't like the results very much, to be honest. The first crack started after around 10mins so I decreased the temperature to ~180*C and I think that this stopped the crack from continuing because I just didn't hear it any more. I stopped the beans at the 17th minute.
Starting weight - ~180g
Ending weight - ~150g
Change - ~16-17%
I ordered a digital thermometer today and it should be here by Thursday. I'm guessing that the thermostat of the convection oven is way off and this is causing my troubles. I'm a bit worried about not hearing a strong first crack and also that there is quite a lot of chaff still attached to the beans. What do you think?
Can you recommend me something like a roast profile? Not really a roast profile but more like what temperature to aim for at what time. For example, 220C until I hit first crack, then decrease it to 180C during the crack to stretch it out, then up it to 240C until I hear 2nd crack. Something like that, just a guideline.. Thanks!!
