My recent roasts were done with "Turbo Crazy" method:
West Bend Stir Crazy 6 qt. model, base part only (unmodified). Mine is
120V model but gave about 100V so that the heater is operating at
about 700W instead of full 1000W. The agitation is slightly slower
than normal but it is ok. The lid-heater assembly of the Turbo Oven
(unmodified) directly sits atop the base of Stir Crazy. Preheat to
175C. Throw in the green bean, bump up the thermostat to 200 to 250C
depending on your planned roast profile. No manual agitation required
as the Stir Crazy does a good job on it.
I didn't push the capacity limit so I can't tell the maximum batch
size. 350g batches were a piece of cake. I also did 200g batches with
equally good result. I see no reason why you can't roast a single seed
in the same way. Also, this method does not have a problem with small
seeds like Alpenroaest does.
The diameter of Stir Crazy is slightly smaller than the diameter of
the Turbo Oven's heating lid. However, the Turbo Oven sits on the
handles of the Stir Crazy with no problem as long as the whole thing
is on a stable level surface. This way, the lid sits slightly ajar,
and smoke and silver skins escape through the gap. I suggest to close
one end and leave maximum gap at the other end, so that skins are
ejected at one side instead of all around the device. Overall, only a
few silver skins are burnt during a roasting session and does not add
the burnt smell to the coffee. Because the whole air volume is
smaller with this combination than the glass bowl of Turbo Oven, this
loss of heated air is not a problem at all.
Because I didn't cut the heater wiring of Stir Crazy, I can make
popcorn in it if I want (though I highly doubt it). The clear plastic
cover that comes with Stir Crazy is convenient when washing buches of
spinach. It has covered holes so that you can wash and then drain in
it. If you attach a large fan at the bottom, you might be able to
make a good bean cooling apparatus, which I might try myself later.
This set of apparatus is very quiet operating and I can clearly hear
pre-first cracks, first cracks, distinct silence, and second cracks. I
can also see the color change and smell the aroma change. Therefore, I
highly recommend this combination for anyone who wants larger batch
size, better monitoring and control over roast profile, or an
inexpensive alternative to home use coffee roasters. You can safely
return your budge of honor given for those who broke many HWP.
