Topic: Handy Pop'n Serve ... any prior art? (20 msgs / 404 lines)
1) From: Michael Wascher
Has anybody tried a Black&Decker "Handy Pop'n Serve" for roasting?
I just got one from a yard sale, thought I'd check for prior art before
continuing.

Mike,
I believe the Black & Decker is a re-branded Poppery II (or clone). 
All of the info regarding the P II should be appropriate for the B&D.
Mike (just plain)

3) From: Michael Wascher
I believe B&D did buy the line, but this isn't a Pop2.This is a completely
different beast.
A low base, an impeller draws air in horizontally from the front, into a
round chamber. Mica vanes force air up past heating coils. The popping
chamber is a clear cylinder that fits on top of the base. The bottom has a
metal plate with slots that direct air in different directions, swirling it=
.
A top with a few slots for air to get out.
Circuitry is simple -- 2 on/off switches (slide switch for the user &
interlock for the top), fan, safety overtemp device, and heating element.
All wired in series.
I'll get some photos up later.

Sounds like one I haven't seen.  Looking forward to the photos.  I did
a couple of searches and couldn't find any pictures.

Here are some photos' of the Black & Decker Handy Pop'N Serve:http://pages.google.com/edit/wascher/handypop%27nserveI haven't tried it yet. The base has a screened opening, which some folks
say can be an safety issue for roasting, but theres also a diffusing plate
above this, in the base of the top piece. The other concern is power, this
is only a 900 Watt unit.
Is 900 Watts enough? Has anybody had success with any 900 W poppers for
homeroasting?
Thanks!

Everything's on you, man. I suspect everyone is watching this with serious
interest. Show us what's what!

Yes ... I linked to the editor (which I hope didn't work for you!) instead
of the published page.

Michael,
Your B&D is a new one on me.  Looks sort of cool.
If' twere me:.........I think you got a project on your hands.  A
variation on miKes dimmer controlled transformer fan speed control
will probably work.  Make sure you end up with Voltage controllable
from about 25 Volts down to 15 or so.  25 Volts seems to be the
maximum that the small low voltage fans can handle (and then only for
a short time).  You might want to check the voltage to the fan
(running) while it is still functional, it may be designed for a
different voltage - these things can usually handle a 10 to 15%
increase in voltage - YMMV.  Be sure to try the 'tilt' trick........
as long as you have just a little bean circulation at the beginning of
the roast - it'll give you plenty of bean movement when the roast
progresses.
I don't think the 900 Watts will be a problem - most folks spend their
time trying to slow popper roasts by dropping voltage to the heater
using variacs, long extension cords or various other tactics.  Using
the dimmer / transformer thing to control heat may have a following,
but in my experience....even 900 Watts is more appropriately managed
with something more comfortable with the 7.5 Amps that the heater will
draw....like a 7.5 Amp variac.  Before you get involved with heat
control,  you may find that you don't need much - if any...... the
extension cord trick may be perfect if you don't need much.

Michael,
When you start trying to roast with this thing, remember:  Many of us
who roast with various poppers aren't looking for the 6,7 or 8 minute
roast.  The 'sweet spot' for some of us is the 12, 13 or 14 minute
roast.
Mike (just plain)

11) From: Michael Wascher
Thanks Mike (just plain)!
My first attempt will be with the unit stock. If it doesn't manage some
level of success then I'll rethink this.

Mike,
There are other differences WRT the more common Poppery, other than reduced
power, that would reduce temperatures & increase the roast time:
   1. The relative proportions. The top is 6" across and 8" high.and the
   diffuser plate is 3 5/8". So the hot air fills a huge volume compared to=
 a
   Poppery.
   2. The diffuser in this unit (3 5/8" in diameter vs. under 3" for the
   Popperies) spreads the hot air over the entire area of the pop chamber's
   bottom, whereas the Popperies have hot air entering  a more restricted
   region of openings around the periphery of the roast chamber. Heat energ=
y is
   diffused over the entire cross-section of the roast chamber before it en=
ters
   the chamber to contact the beans.
   3. The Popperies have a rather large metal chamber, the sides & bottom
   of this heat beans by conduction & radiation. This unit has just a flat
   plate on the base. Beans will be separated from this by the diffuser & a
   half inch air gap. There will be no conductive heat transfer from the si=
des
   & bottom of the roast chamber, and much reduced radiation of energy to t=
he
   beans.
So there are a lot of things that will reduce the heating & extend the
roast. The one item that works against this is the top. Airflow is
restricted more than on a Poppery which should increase heat. It'll be
interesting to see how this all comes together.
I'm not sure how to size the load on this unit. Maybe start with 70-100
grams of beans? A Popper 2 sized load. Now to find some time.

Michael,
<Snip>
I think you have spelled out your major concern (the size of the
poppers chamber).  This is going to be the biggie, will you be able to
get good bean circulation?  I just don't have any feel for how this
configuration will support bean movement.  Trying it at different
angles while filling it with greens until you have minimum bean
movement, or fill until there is no movement and remove a little are
the norms for sizing the load.
Mike (just plain)

I had (have?) one of those, somewhere. IIRC, it didn't make into my 
Hall of Fame. Maybe, Mike's rundown will remind me as to why...
I do remember getting excited when I bought it at the local thrift 
shop, but I also have a vague recollection of disappointment.
Ciao,
A+

15) From: Michael Wascher
I tried a couple of roasts -- 96 grams and then 48 grams. I did get roasted
beans. This unit generates enough heat, but the fan doesn't move the beans
around. Bean movement is very limited, and despite the diffuser is localize=
d
to the area just above the screened opening in the bottom base.
Lots of stirring, then put the top back on to keep the heat in ... result
was uneven roasts. Links to the roast are at the bottom of the page linked
below (which was also updated).
The visibility of this unit is nice, but stirring with a wooden spoon just
doesn't do it. I don't think the airflow can be increased sufficiently.
Adding a stirring device of some sort would seem to be the solution. I'm no=
t
sure it's worth it as long as other suitable poppers are around.http://wascher.googlepages.com/handypop%27nserveOh, my attempts to discern the wiring while looking through a 2" tube
failed. The slide switch turns the unit on & off. The interlock just turns
the heating element off, the fan keeps on running.
Bottom line -- I wouldn't recommend this as a coffee roaster.

16) From: Simpson
I tried for some time years ago to make this thing work, but it is, to cut
to the chase, cr*p. Not only is it a lousy coffee roaster but it can't even
pop popcorn well. Too cold, too diffuse and weak an air stream. Cr*p.
However, it contains a true gem, to wit, the white silicone gasket at the
bottom of the plastic vat. Nowadays when I find one for 3$ or less in a
thrift store, I smash the bottom out of the plastic jar with a quick hit
from the inside out and toss everything in the trash at their register, all
but that gasket. I probably have ten of them in storage. It is a handy
thing for a do-it-yourself coffee air roaster builder because it makes it
so simple to couple devices together, say a blower box and a heater box,
using that excellent, temperature resistant gasket as an air seal.
Here is an example of their use in an old version of an electric
VolksRoaster. I hope this image thing works... it is my first try...http://static.flickr.com/47/142072136_7a5a82f9f1_o.jpgJust my opinion, of course.

Wow!  How did the chaff seperator work out?  More information on the
project please!

Ted,
The heating element itself is probably useful too. A nice microswitch.
But yea, as is it needs some serious help.

Actually, it is really well built, it just didn't work! LOL. As to the
switch etc, I switched to gas and so became as blind to all cool electrical
things, I'm afraid.
