Topic: Turbo Crazy 530g batch (42 lines)
1) From: Ryuji Suzuki -- JF7WEX
There has been few postings on this topic, so here's one.
I have been using Turbo Crazy with modified agitator for increased
evenness of roast with approx. 300g batch size, but this time I
roasted one straight roast for myself and friend together, so I did
530g batch. The bean was Nicaragua Segovia Canta Gallo (long out of
stock but I kept some as I like it a lot).
My setup uses Stir Crazy at 70% of ots nominal power. Without lowering
the power, I have a problem with roast being too quick with smaller
batch sizes. But even with reduced voltage, agitation was no problem.
It was mostly the issue with original wimpy thin straight wire
agitator that scratches the bottom that caused the problem in my early
use of this setup. Roast time was as usual, and I was very comfortable
with this balance of bottom heat and top heat.
One problem is that the hollow is not deep enough to comfortably hold
this amount of bean. Cake ring of very appropriate size seems
necessary for comfortable roasting of this size. I had to adjust the
levelness of the surface after starting roasting because otherwise
beans would spill off one side. Also, when bean cracks, it sometimes
jumps in to Turbo Oven assembly and makes noise with the rotating
blades. The blades are sturdy so I didn't care but this may make
people nervous. Again, appropriate separation by 4 to 10cm would solve
all these problems. Even with this close spacing between the bean and
top heater, smoke wasn't a problem at all. I do all my roasting
indoors by the window with a fan.
I have tried a number of things from time to time, but I haven't come
up with more permanently usable parts for separation. If you see
someone measuring dimension of cake rings in store, that's me :-) I
even think I should take a stainless steel sheet and make one myself.
