Topic: 1st Stir Crazy Roast (11 msgs / 256 lines)
1) From: MMore
Last night, it was a Kenya Auction Lot - 10 Oz.  Disconnected the  heater 
element.
 
Now - one question.  When the roast first started, and for the first  couple 
of minutes, the stir arm would reverse direction a couple of times.   Is this 
normal and to be expected?
 
I started the SUNPENTOWN at 390 degrees and kept it there until first crack  
- around 10 minutes or so.  Curiously enough, I couldn't really tell when  1st 
crack was through - at around 12 min. or so, I could tell by the smell and  
sight that the beans were getting 'done'.
 
Question #2 - is 1st crack more 'subtle'?  Should I roast at a higher  temp. 
to reach 1st earlier and more pronounced?  
 
Veterans of the SC/convection roasting wars, I welcome your comments.
 
Thanks!

quick note... I always bump up the temp from 390 but not far.. maybe to =
450 but a min or 2 after first crack subsides...just to make sure I 
actually make it to temp for 2nd crack...

That's interesting Dennis, since I have the same setup (SC heater
disabled).  Maybe the temperature settings on the Sunpentown are not
uniform between units, or maybe we have some voltage differences.
With a temperature setting of 390 for the whole time, I hit first
crack around 6 minutes and virtually no time between first and second
crack. I've now dropped it even a little lower - around 370-390 for
the whole time.  With this setup, my first crack starts at 7 minutes
and ends at 9 minutes, with 2nd crack starting around 10 minutes.  The
reason I've lowered the temperature is because I've heard that it is
good to have a clear distinction between 1st and 2nd crack.
I have also found a way to remove more of the chaff during the roast. 
The first time I roasted with this setup, I had the Sunpendown exactly
centered on the SC and wound up with tons of burnt chaff inside.  But
I've found that if I keep both units flush on one side and have a
bigger overhang on the other, more of the chaff escapes.
I also think my roasts taste better than with the Poppery, although I
can't really explain why.

heheh yup! i do the same thing!  as far as offsetting my Sunpentown/SC 
Im sure there is some difference in Voltage as I always get about 3-4 
minutes between first and second crack... both very distinct..also... 
what volume are you roasting? I do 2 heaping cups.... 34 oz. as 
standard... a do adjust and compensate as needed  bean to bean....
Also, the beans that roast slower like in a drum roaster tend to be 
smoother with more body but loose a touch of the brightness a fast 
roast like the fluid bed roasters provide.. both have their benefits 
such as brightness maybe good for drip or MOKA pots and drum or 
espresso as it smoothes out the BITE and adds depth... its a preference 
and I agree I love my Supentown/SC setup...!

That's probably it.  I've been roasting 1 to 1 1/2 cups at a time
instead of 2 heaping cups. In the popper, more beans usually raised
the temperature of the bean mass.  I guess it's just the opposite with
the SC/Turbo oven setup.  BTW, we need a better name for this roaster
combo. I never know if I should say SC/GG, SC/Turbo Oven,
SC/Sunpentown!

yea..I agree... problem is...  each of the machines might have separate 
controls or idiosyncrasies and its nice to know which you are talking 
about in case of difference that is machine specific....  maybe just  
Turbo Crazy (Sunpen,GG,ect...)  that way it will have an identity and 
be happy! hehehe

My SC heater is still active (and I think I'll leave it active for
winter roasting), so my GG starts out at 325 until first crack is
through.  First usually starts at 7:00 and ends at about 8:30.  After
first is done, I lower the heat to 300 for a couple of minutes and
then I kick it up to 350 until I get to second crack (usually at about
12:00.
...ron

8) From: MMore
So, what's with the stirring arm going one way for a while, then reversing  
direction for a while.  It has done this a couple of times, early in the  roast 
(usually within 1-3 minutes) and then stopped doing it for the rest of the  
roast.  Anybody else experience this?

The Stir Crazy  is designed to reverse when it meets resistance, so
the popcorn doesn't get stuck under the arm and burn! As the coffee
lightens there isn't enough resistance to cause it to reverse.

Wish I  had saved the reply from West Bend... the tech said that the 
arms rotate at 12 RPM, and they reverse direction normally when they get 
stuck. This is normal because the motor is asynchronous (?), or 
synchronous, whichever term applies to a motor that can run either way.
