Re: roasting questionsYeah Bob, I'm aware of the drawbacks of a full-on/full-off device like an
air-popper. That's why I'm working on making my TurboCrazy programmable.
I've got a thermocouple J&B Welded to the floor of the TC now (had to dimple
it so the rotating arm would clear the t/c) and I can manually run profiles
now on my beans using a digital thermometer. I'm figuring out how to use a
PID with a soak program to convert the TurboCrazy into full auto profiles
(someday I'll figure it out - hopefully?).
The thing I'm shooting for is roasting the beans to AA degrees and hold it
there for XX seconds, then roast to BB degrees and hold it there for YY
seconds, etc., etc.; then dump the beans immediately into the colander and
cool as quickly as possible. I'm hoping for a more exact profile this way.
That's the problem I have with the idea of drum style roasters that hold the
beans internally for a cooling cycle - one too many variables.
With the TurboCrazy and the profiles I use, I believe I'm more closely
mimicking the professional roasters (Dietrich, et al). At least all of the
ones I've seen stop the heat as soon as their target temp is reached and
cool the beans externally. That's why I was wondering about whether the
beans are continuing to cook during the cool-down cycle of the drum roasters
and how much effect it might have on flavor.
