Topic: Popper roasting (27 msgs / 525 lines)
1) From: Richard Estes
Poppers can be vastly different, even the same brands/style. I currently
have two original Poppery's, both modified with the glass lantern globes.
Empty temps on one are 360 degrees, and the other gets up to 405. they both
roast excellent, though one a little slower. The roast time varies
drastically according to the bean and the ambient temp.
It would be great to have schematics for bypassing the thermostat and
installing a temp control to the heat elements if anyone has these
available.

Orig Popperies have an adjustable thermostat so there"s no need to =
bipass it. You can just set it so high that it will never open. If you =
open up the Poppery, on the heater curcuit you will see two or three(I =
forget) strips , about 3/16" x 1" sandwiched together with a small set =
screw in the top strip. Just screw the set screw in (clockwise, pushing =
it against the other strip harder)as far as it can go without coming out =
of the top plate. This will, basically, eliminate the thermostat. 
Making the heater adjustable will cost a little more. I just use a =
switch to cut off the heat but to actually control it you can use a =
dimmer switch. The problem is that standard dimmers are only rated for =
600 watts, less than half of what you need. A dimmer capable of =
handling1500 watts will run over $75.
Good Luck,

http://www.mlcswoodworking.com/shopsite_sc/store/html/smarthtml/pages/speedcon.htmlThat looks as if it would be more than adequate for controlling the heater (to reduce output, 
anyway), at least if it's rated for "continuous" use, and not the intermittent use it would see 
from a router (which is almost never heavily loaded for long).  One never knows about such things 
without trying . . . (though putting a fan on the controller box would probably resolve any "duty 
cycle" issues).
You would probably not get a reliable reading of output from an ordinary voltmeter (because of the 
way the control "chops" the line input), but you'd probably want to be monitoring the air 
temperature and adjusting to that, anyway . . .

anyone knows the wattage for the heater *only*, please post.}.
The fan's maybe 30-50 Watts.  The power's all in the heater. Don't know about the Poppery, but the 
Caffe Rosto heater is 11.5 Ohms cold . . . (a bit less hot, but I haven't measured it) . . . so 
figure it at 1150-1200 Watts minimum.
note . . . the heater is a purely resistive load, easy to measure . . . the fan, being a complex 
inductive load, can only be measured while running.  For comparison . . . I just looked at a 14 
inch "oscillating" fan that I've used to exhaust roasting smoke (it moves a lot of air) . . . it's 
rated 80 Watts.

The fan motor uses 0.8 amps.  Or, about 100 watts.  The rest is all heater.

Please forgive my electronic ignorance, but the description above says
"electronic feedback maintains speed by increasing voltage to motor as load
increases".  Our goal is to regulate the voltage for the roaster; wouldn't this
device actually *deregulate* the voltage as the fan cycled on and off?

You may not want to use this router control on a roaster with electronic 
controls like the HWP. I remember a thread long ago that warned against
using dimmers on the same circuit. If this speed control chops the ac like a
dimmer, then it could confuse the microprocessor or even damage it. It
should work on poppers, so I bought one. I will let you know how it works.

controls like the HWP.
Quite right, on two counts . . . the switching noise might well "befuddle" the HWP controller and, 
more to the point, will defeat its purpose (which is to control temperature in the roast chamber by 
modulating the airflow).  The HWP is quite capable of dealing with too high voltage on its own . . 
.. like most air roasters (but not as bad as most) it does less well with too low . . .
<Snip>
Ah ha . . . another bold experimentalist . . . welcome . . . 
If it fails (unfortunately it might . . . I suspect that it's "ad copy rated" for peak load, not 
continuous load) it will be from overheating a single component in the box (probably packaged as a 
centimeter square thingie a couple of milimeters thick with three connectors on one side and a 
metal tab (hopefully screwed to a heat sink of some sort) on the other.  With a continuous load 
(like the heater) it will get very hot.  Anything that increases airflow around it (to cool it 
down) will prolong its life.
Check the packaging or "instructions"  for the disclaimers that don't make it into the ad copy . . 
.. it will say somewhere "not for use with induction motors" and may say something about "lights, 
heaters, or other continuous loads above xxx Watts".  If the warning is there, and it fails, you'll 
probably have to lie to get your money back . . .

 From time to time I see posts concerning the modification of various types of
poppers, usually the Poppery.  I now roast in a Proctor-Silex Popcorn Pumper. 
My first roaster was the Hearthware Gourmet but I soon switched to the
Precision when I had problems with the Gourmet.  A year of wearing ear plugs to
block the noise plus the tedium of standing around for nearly an hour to roast
enough coffee to last four to five days finally prompted me to look for a
roasting alternative.  I happened to have the Pumper lying around the house so
one day I pulled it out and gave it a try.  
I put in half a cup of beans as I would in the Precision.  Sure enough, as I'd
read in other reports about popcorn poppers the roast stalled out before it
could complete first crack.  But one thing I noted was that the beans were
spinning about the roasting chamber very quickly.  I  tossed out that batch and
decided to double the amount of beans and put in a full cup.  This seemed to be
the perfect amount.  The beans start off in a slow rotation around the chamber
and within about a minute those that started out on the bottom are beginning to
show up on the surface so that a whirlpool effect is created.  I hit first
crack at about four minutes and second usually begins at anywhere from six to
seven minutes.   
To top it all off, the plexiglas top of the Pumper makes a perfect funnel when
turned upside down and placed over the glass bowl of the Hearthware Precision. 
I crank the knob on the Precision to about 3, the beginning of the cooling
cycle, pull the plug on the Pumper and quickly pour the contents into the
Precision which is already blowing cool air.  
So with no modification to the machine whatsoever I'm roasting twice as many
beans at a time.  While one batch is cooling in the Precision I've begun
another in the popper. In under 25 minutes I now roast and cool three cups of
beans that are to me better than any I roasted in the Precision alone.  And I
can actually hear every snap of second crack without damaging my ears. 
Paraphrasing Voltaire in Candide, this seems to me to be the best of a possible
worlds.

This is what I do with my Poppery I and my Gourmet (especially since the 
third circuit board failed...)  Works well.

Since you were looking for info, I use a standard, unmodified Poppery I 
for roasting.  Works well, roasts about a 2/3 cup capacity, will roast 
to a dark, oily sheen with no complaints and little noise.  Once the 
roast is done, I pour the beans into my Gourmet and use the cooling 
cycle of the Gourmet - found I was losing too many beans pouring them 
back and forth between collanders.   :-)

You used the model "Precision", but from your description if the knob setting
and cooling cycle, I think you are describing a Hearthware "Gourmet".  On my
"Precision, I could do the same thing, but would have to press the cooling
button for a five minute cooldown.

Hello to all of your good selves!
Having lurked but never posted, here goes.....
I have been happily hot air gun roasting for a while now but thought I'd
try popper roasting yesterday. Anyway, after 10 mins I still hadn't reached
first crack so I gave up assuming that the popper wasn't getting hot
enough.
I had the lid on  to keep the heat in but this didn't seem to help at all.
Any tips and tricks?
Cheers

What is the AC line voltage?  It might be too low.  Does it get HOT or only
warm?  What type of popper are you using?  I've used six different Poppery
IIs and each one roasts differently.  I did find two that were very similar
(about 30 seconds difference).  Anyway, you might need to try another
popper.  If you're using a Poppery II, I've found 3 oz. of green beans to be
the average batch size.  I have one that will do 3.5 oz. but I have to tilt
the popper back so the coffee doesn't fly out after first crack.  It has a
really strong motor.  How much coffee (by weight) are you roasting?

24) From: Bernard Gerrard
After my first couple of batches I found that using a bamboo chopstick 
to stir the beans around for the first part of the heating gave a 
consistent roast.  After the beans begin to brown (and swell) the 
machine will keep them thoroughly agitated.  Sorry if this notion has 
been aired before.....I'm new here.  Bernard

"...if this notion has been aired before [I don't recall it,
Bernard].....I'm new here." Me too. Even after a coupla years, every day
seems new. There are lots of new hints and ideas to digest.
This begins to sound like a neat way to practice with chopsticks...

26) From: b cook
When I was still doing air popper roasting I would just shake it a few times
in the first minute.  If it's not jumping up and down on it's own by a
minute in the batch is too big IMO.
I think the shaking habit has followed me to the SC/CO though...I can't
resist.

I use the chopstick option and have found it to work well. It's small enough
that it doesn't get in the way or pop any of the bean out of the roast. I
also haven't found it to burn ... much ;- )
