Topic: 50f ambient Rosto roasting (7 msgs / 161 lines)
1) From: Mike McGinness
Temperatures are dropping here, down in the 30's nights. The garage was
50f. Just roasted some Sulawesi using my 'hotter' Rosto (runs 'bout 10
hotter than my older one.) I usually target 380f in 6min ramp then 1min per
10f development stage. I decided to go 118v flat out start and see what
happened. Too fast! (no box or other recirulation aids) Just plain old 118v,
hit 380f in 4min, dropped voltage to 112v to go into development ramp,
adding 'bout 1/2v per 10 to 410 then to 115v then 118v at 420f for the
final 15 to 445f. Kept the ramp rate at 1min per 10f from 380f and never
exceeded 118v. Just right 6:30 development stage target, just touched 2nd,
very even roast, especially for Sulawesi!
(Much evener than my earlier microwave attempt to say the least, and it was
Panama Songbird:-)
Again, I say anyone's Rosto who can't make charcoal with a 151gr weighed
batch at 60f or higher ambient needs to send it back for exchange!!! No box
or other recirculation needed till way cooler, as in near or below freezing.
50f no problem here...

This time at 22f ambient, I preheated to about 200F first then added my 
beans.  First crack occurred right at 5:30 where I expect it and ended 
about a minute later at 6:30.  Holding my self back, I did not cut the heat 
like I normally do.  The first pops of 2nd started about 7:30 and was 
really snapping at 8:30 when I cut the heat and started cooling.  Not 
surprisingly, bean were cool in two minutes.
With a preheat and no post 1st crack stall, my 22F roasting was the same 
profile as my 50-80 degree profiles.
The power of poppers.  Wondering just how cold this WB can handle?

I am not sure what constitutes a Mk I but it is a modified WB I.  Maybe an 
Alchemist I ?

As part of my modification, I completely removed the thermostat and 
hardwired the heater.  I also installed another post and switch to control 
the power to the heater and main power independently.  Finally, I changed 
fan blades, removed the original fan plate and have left the bottom off, 
all to increase air flow and moderate the killer heater.

John,
I roasted  when I lived in Wisconsin when it was 15 degrees below, and I
roasted outside!  The beans cooled really fast!

Wow, I guess I won't get to test out my roaster's limit ( I hope).
This morning it is 20 F and I just roasted up some Jampit that I received 
Friday (BTW, for you Jampit lovers, did you notice it is now in limited 
supply and by the pound only?).  Those 2 degrees made a difference this 
time.  1st crack was where I expected it, at about 6 minutes, but 2nd was 
delayed to nearly 12 minutes.
Thinking about the mods I made on my WB to lengthen the roast, I put the 
lower cover back on and roasted again. 1st was at about 4 minutes and 2nd 
between 6-7.  Looks like with the lower cover, I am fully in business again 
(not that I was out, but 11 min was a little long) and will actually need 
to stall my roast after first again to achieve the 8 minute roasts I like.
