Topic: New experiences with a P1 and a cooling question (2 msgs / 60 lines)
1) From: Ron Sand
I have been playing with my newly modded P1.  I separated out the fan =
and I
am controlling the heat with a light switch while awaiting my variac.  =
150g
of green beans seems to move well so that is what I have used.  I am
monitoring bean/exhaust temp with a dial thermometer (starts out with
exhaust temp and the beans reach the thermometer as they expand).  
I was very pleased with my first roast of Yirg Horse lot 4452 - much =
better
than the 3'51" roast with my unmodded P2.  I ramped up to the first =
crack in
6'10" at 370F and ended in 13'34" at 445F.  Tonight I tried a gradual =
ramp
of 25F/min from ambient to 445F in 15'45" with the first crack in 12'15" =
at
375F.  Neither roast reached the second crack and they ended at a city =
roast
(my thermometer may read a little high according to the temps listed in
Tom's pictorial guide).  I will have to see how it compares after a =
rest.
Both roasts were cooled in the popper to 125F in 5 min.  
Which leads to my question - is that too slow?  I am limited for space =
right
now and I am trying to avoid making a cooling device.  Any comments on =
the
roast profile would also be appreciated.

I get roughly the same time, and it used to be a lot faster on 
the FR or lighter poppers. However, I don't notice a taste 
degradation. I think it's because it does drop the beans below 
300F (out of roasting range) in under a minute, and slows down 
after that. But I haven't experimented with a side by side lot 
of collander cooled beans
