Hey Tom, The secondary heater coil is there to reduce the voltage to the =
fan motor, although it does heat some, the temp. is only about 150 =
degrees, and yes you can cool your roasted beans to 200 degrees in about =
2 minutes, and then dump them into a colander, to completely cool the =
beans. Faster is better, but anything under 4 min. is OK.
good luck with your roasting.

Hi all,
I have a Poppery II that I've modified by disabling the thermostat and
installing a switch for the main heating coil. I'm now waiting for my beans
to arrive so I can try it out. My question is, since I have a switch
installed, can I just turn off the coil and let the air flow cool the beans
when the roast is done? Or would that not cool them fast enough? I know that
the second coil is still on but the air coming out is barely warm.
Tom
P.S. I'm not much of a BBQ'er, but I do make my own maple syrup. Does that
count for anything?

At work, I discovered a *spare* 12vdc Nidec fan,  a 2 inch square for Compaq
server power supplies.  With a 12vdc wall adapter this things REALLY moves
some air.  At the end of a roast last night, after the heater was switched
off on my WB I remove the FR top to aid with the cool down and then I added
this fan atop the tin can extension blowing up and the temperature in the
bean area plummeted to below 200 in a minute or less.
I think possibly the WBII would cool down faster with just its fan because
the roast chamber is thinner aluminum.
Respectfully,
Rich Adams

The beans will cool fast enough to quench the roast. I suggest dumping the
beans on a cookie sheet after 2 to 3 minutes to finish the job. The
secondary coil and motor heat is about 250 watts, so it is significant.

I did exactly the modification you refer to on my WBII, switch to turn the
main coil on and off.  When I switch off the heater, and run just the fan
and smaller coil (I figured about 45% of the 1200 watts), cracking
immediately stops and I am down to 250* in less than two minutes and then
pour the beans into a colander.  I think the 250* is a deceptive reading, as
I can handle the beans without burning my hand.
I am also trying to copy the roast profiles that Kona Mike has referred to,
and find by cycling the heater off for four seconds every so often below
400*, and for 2-3 seconds above 400* that I can maintain a steady
temperature and also ramp at 10* per minute.
