Any one tried roasting in a microwave oven or as a pre heater to
roasting in a light weight like the freshroast?

4) From: Jim Gundlach
Since microwaves heat by activating water molecules and roasting  
requires temperatures beyond 212 F, I don't see how it could work.   
There is the possibility of using metals that microwaves can heat but  
that would seem to take a lot of development work and would be a far  
more complex process than any of those used by people on the list.

Hey, he edited the subject line ;)  it's just one of those digest mail things.
I have thought about this, but not sure it's easily done.  There are
things that can brown stuff in microwaves, so you'd think it's
possible to warm something without blasting the water straight out of
it, which microwaving tends to do.  I'd be interested to hear if
anyone has come up with a way to do this.

6) From: Michael Wascher
The Kenneth Davids book "Home Coffee Roasting" has a few pages about two
tentative designs for a microwave coffee roaster called "Wave Roast". The
roasters use packets or cones that are pre-loaded with beans, they heat the
beans using microwave & radiant energy (I'd guess that they have a foil
liner like packets of microwave popcorn.
Has anybody actually seen this product?
Were I able to obtain some unused microwave popcorn packets (I mean with no
popcorn or greasy glop in them) I'd try them for roasting coffee After all,
hot air poppers work as coffee roasters!

Once upon a time there was a company called "Smiles Coffee" that claimed
'the freshest, most flavorful coffee you'll ever taste'. It was par-roasted
coffee in small "finish the roast in the microwave" just before brewing
packages. A number of us on the List tried it in the name of science. The
stuff was beyond terrible.

9) From: Michael Wascher
He mentions the Smiles product, describes it as pre-roasted beans in a
packet that is microwaved.
The microwave roast products described were "tentatively" to be called Wave
Roast. The drawing showed a "tentative" design. So I presume that this
wasn't an actual product at the time the book was written. Perhaps they
never made it to market.

Back in '02 Smiles Coffee was open for business. Here's my post from
themeyers.org archives about it from back then:
Topic: 'Frowns' microwave "roasted" coffee (4 msgs / 83 lines)
1) From: Mike McGinness 
Argh! Mine arrived today. 'Roasted' the Kona Blend for 1:15 (suggested time
for medium roast in 900-1100w 1:00, ours is 1100w) Cut open the bag, smelled
simply terrible. To be fair, I ground and pulled an Americano. Tasted as bad
as it smelled. Opened the 'unroasted' 2nd bag of Kona Blend. Gee, they
looked identical to the microwave 'roasted' and smelled just as bad too.
Basic smell of very stale beans plus something else I'm not sure what. Ok,
maybe it's the Kona Blend that was so bad. Nuked the Sumatra for 1:25.
Opened it and the un-nuked 2nd bag of Sumatra, again looked virtually
identical. If any thing the nuked smelled worse. The nuking intensified the
foul stench. Ground enough for a double shot for Americano, inhaled the
aroma of the grind, and dumped it down the drain. I just couldn't brew
another of this crud. Flushed my grinder with some fresh roast (not Smiles,
mine), then ground and brewed a Wood's Kona Americano. Lisa's right, the
LaPavoni whirley chop will make a nice intro to ground coffee gift. Not too
bad for $9.95. Reality is this Smiles coffee supposed microwave roasting
isn't roasting the coffee at all. It's already pre-roasted. They're just
heating it for unsuspecting people to smell the illusion of fresh roast.
Terrible stuff. MM;-) Variable Variac Rockin' Rosto Roasting Miss Silvia

End of that post.
I did make one attempt at actual microwaving true coffee greens:
From: Mike McGinness 
After the 'Smiles Coffee' fiasco I decided to see what would happen
microwaving true coffee greens. (rather than the 'Smiles' pre-roasted
microwave heated stuff). I put 3oz greens in a covered glass microwave safe
bowl. (cover on loosely at angel) Started nuking on high, heard what sounded
like 1st cracks starting 'round 1:30 then shortly after sounded like some
2nd's kicked in with the 1st's. By 2:50 smoke was starting to billow so shut
down! Beans ranged from green to black. Another down the drain experiment!
Oh, this was with a 1100w microwave with carousel. Too bad it didn't work.
Anyone figures out how to really roast coffee with a microwave and that
would be great for many vacations! Maybe using lower power. Me thinks I
seriously ought to spend some time learning to stovetop coffee roast... Hey,
it was a thought!:-) MM;-) Variable Variac Rockin' Rosto Roasting homeroast

13) From: raymanowen
"Has anyone developed any microwave roasting techniques?"
YES-
I DON'T, and that's only half of the story.
The energy distribution of the rf field within the oven's chamber has
gigantic variations, maybe 1,000,000:1, due to standing waves. Hence, the
carousels or stirring fans.
The rf wavelength of microwave cooking ovens in the US is not microscopic,
but it's about 5 inches. That's one of at least two reasons that
electromagnetic (radio/ radar) energy can't be used to heat and roast the
likes of coffee beans.
As mentioned, the beans are much smaller than the wavelength, so can't
develop much electrical potential over their surface (antenna is far too
short for the frequency.) Practically, the beans are "invisible," or don't
exist.
The metal mesh in the microwave's door window has holes that are tiny,
compared to the rf wavelength. People sure can't see microwaves- so why do
they watch something they can't even see? Instead, they should be worried
that the microwaves could be squirting out the holes and frying dots in
their eyeballs.
Water boils at, say, 212 F, when you're floating around at sea. Meat is
safely cooked below that temperature. Bread is baked at about 320 F, Piz=
za
bakes around 400F. Popcorn pops about 300F, due to the expansion of t=
he
trapped moisture. How many of these foods are appealing when they are cooked
in a microwave oven?
What is the prospect for coffee roasted in a microwave, compared to the real
thing? Kinda' like microwave popcorn?
Aged several minutes, ground with a hammer- save the good stuff for later,
lots later.

14) From: Michael Wascher
There is no need to "develop potential" across the beans.
The RF is AC. The EM field keeps changing, it flips back & forth. This
causes polar molecules (e.g. water) to flip back & forth ... their vibration
causes heat.

Who cares about the theory! Nuker can most definitely "see" coffee greens.
Earlier today I already posted that when I tried nuking 3oz of greens back
in '02 at 2:50 minute point I shut 'er down 'cuz smoke was billowing with
result of mixed charcoal black and still mostly green beans... Don't recall
if they were a single layer or a pile...

No water, or other polar molecule, and the microwave won't heat the object.
But other than freeze-dried foods, there's quite a bit of water in almost

212 is the magic point where water boils into steam (vapor pressure =
atmospheric pressure), but I would think the microwaves would continue to
excite the water molecules in the steam and will continue to heat up hotter
and hotter.

"Microwaves will happily heat oil far above 212"
Therein lies the problem of using electromagnetic radiant energy to heat
anything which requires precise temperature control. Energy will tend to
flow to the colder mass until its temperature matches that of the energy
source.
Infra Red and microwaves are the same form of energy, and have no specific
temperatures. Successful implementation requires continuous monitoring of
the bean temperature and control of the energy source- usually by PWM, as in
the inverter controllers.
