Topic: Two minute roasts (4 msgs / 86 lines)
1) From: Scott Marquardt
Soooo . . .
I was reading some patents on-line. The Proctor and Gamble folks were
certainly doing some big-bucks research back in the day. Those thirty-year
old patents make for some striking reading. A lot to learn there that ya
just don't hear of on homeroasting boards.
Well how about it? What's a homeroaster to think of the notion of 650 degre=
e
environment temperatures in a fluid bed, yieding a full city in two to thre=
e
minutes?    ;-D
And how about that business of drying the beans in a 105 C fluid bed for a
few hours, in order to get their moisture content to about 5% before
roasting in order to ensure maximum inflation of the bean to optimize
extraction? Before roasting at 650 degrees F for a couple minutes, that
is?   ;-D
Has anyone tried these hyper-roasts? Needless to say, it ain't gonna happen
in a popper, and this is NOT a good candidate profile for a drum.

I used to do a lot of fast roasts in a popper, even a few under two minutes.
Some of the roasts were excellent, but the remainder were merely good. The
excellent roasts were pure luck in stopping at just the right time and
quickly cooling. I began to do some slower 5 minute roasts with IR temp
monitoring and had better results. I planned to do the same on the fast
roaster but then got "sidetracked" by drum roasting over a year ago. It will
be interesting to return to poppers, maybe in the next few weeks.

What'd you use for IR monitoring? What luck with it? Any caveats?
Normally I'd say reading patents would be about as fun as watching
lichens grow, but I gotta say -- this was some fun stuff. It'd be fun
to have your test batches be 1000 pounds, eh?   ;-)

This has been discussed several times over the past few years, you can
search the list archives for more detail, or email me offlist.
I used an inexpensive handheld IR thermometer. Check this one:http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber‘778It may be still on sale at half price.
I will soon be setting up my poppers again after a year of drum roasting. I
use IR for continuous monitoring.
