Topic: update on turbo beast roasting (3 msgs / 86 lines)
1) From: petzul
If I ever get enough interest to sell significant amounts of coffee I 
will be able to roast more, since that is what I like to do mostly.
Today I experimented some more in controlling the roast, keeping in mind 
all that I have read on this list about ramp times and duration between 
first and second, cooling time.
Thanks to everyone.
This is not an automatic roaster, and I have been disheartened by not 
being able to hear first or second crack.
I even thought of attaching some sort of cone to the side of the bowl, 
kind of like an old Victrola, as an aid to hearing these important sounds.
Instead I tried one more time, with a pound of Puro Scuro. I preheated 
to 350, started the mixer and dumped in the beans. The temp dropped to 
280 before it began to rise again, and reached 300 in under 3 minutes. 
Good so far!
In about 6 minutes it was up to 411, so I should start hearing first 
crack. Shut it off and listened.. nothing.
First crack did not start by my indication until about 437F. But then I 
could hear it by just offsetting the turbo oven a bit. No doubt.. first 
crack!
So I kept it offset a bit, letting the smoke and chaff blow out, and let 
it slowly climb to 460+ , and began to stop the machine and listen for 
second.
Doing this I found second crack at about 465. I turned off the turbo and 
let it mix for a few more minutes, happily rolling in second crack with 
no power applied.
At 13 minutes I took the turbo oven off the mixer and let it run in the 
air.
At 13:40 I turned on the hair drier and blew all the smoke and chaff 
away, taking care not to cool too fast and slowly brought it down to 97F 
so I could scoop out the beans 17 minutes into the roast.
The resultant beans are dark brown, evenly roasted, with no oil at all 
showing. Seems just fine to me.
Will see how they taste in the morning.
Thanks to everyone for all the advice and help.
