Topic: 28f ambient roasting this morning (3 msgs / 149 lines)
1) From: Mike McGinness
Made Debi a Monsooned Malabar Americano "to go" as she left for work. And I
was a happy camper, it was last of the roasted Malabar, I get to roast!
Brrr 28 ambient but no biggy. I absolutely love roasting with separate heat
and fan throttle control. My target roast for the 1/3# 151gr Malabar batch
was 465f in 16:30, usual 5min to 350f etc. No problems at all. Max heater
voltage towards end of roast 120v, min fan voltage 92v, only needed 120v fan
for good movement at start! Of course, MM a very light bean to begin with.
Did a second batch, 151gr Kona Mountain. Target roast 440f in 14. Heavier
bean . Start of roast needed about 130v for good greens movement, final fan
voltage reduction towards end of roast 110v. Max heater needed for profiled
ramp 119v. 28f ambient and absolutely no need for box or anything to
recirculate air. No need to push heater even beyond 120v for med-dark Vienna
nicely into 2nd crack 465f roast. The more I use this dual control roasting
the more I love it. Even just separating the fan and running it fixed wall
voltage with heater voltage variac controlled allowed better control and
more even roasts, this makes it even better! I honestly don't know how to
achieve better manual roast control.

Mike,
I'm sort of new to the list and am curious about what your setup is, it =
sounds interesting. I'm currently using an air popper with a thermometer =
and a switch to turn off one of the heating elements

David,
Seehttp://home.attbi.com/~mdmint/coffee/Rosto_mod.htmIt'll give you an idea. (Randy & Deward are roasting with similar setup.)
