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 465°f in 16:30, usual 5min to 350°f 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 440°f 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. 28°f 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 465°f 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.
