Topic: Bean Cooler (25 msgs / 561 lines)
1) From: trwalters
Hi All,
"Y'all" might want to try this...
Get a hot-air popper (any kind will work). Open it up and remove the heating elements. This will also disconnect the motor. Either use an AC transformer and keep the diodes on the rear of the motor, or use a DC power supply and remove the diodes (this is what I did - old laptop power supply). Pay attention to polarity for DC. Hook up the transformer/power supply to the motor. Put it all back together. Get a piece of metal screen or 1/4" mesh hardware cloth (basically chicken wire) that you can cut to fit inside the plastic popper cover. Attach it with silicone rubber. You're done!
Now, after the roast, pour the still-hot beans into your new bean cooler, put on the plastic cover, and turn it on. Your beans will be room temp in about 30 seconds!
By removing the heating element section, you've increased the airflow quite a bit. Mine would blow the beans out of the popper. That's the reason for the screen inside the cover.
If anyone wants, I'll post pics of mine.

sounds great, but make sure the 'chicken wire' is not galvanized.  If it
is, it is coated with zinc and it is toxic, especially when heated.
Fumes from the heated galvanized material and residue from the zinc on
the beans can hurt you.  It can be deadly.

This is a good idea for those burned out poppers. But if the heater is ok 
then leave it, you have a *roaster and cooler* for the practically the same
amount of work. Just add a $4.00 dimmer and you are all set.
Tim, please do post some pics, but (just a reminder) not here on the list.

I have used the following. 
Hair Dryer on Cold setting.   Not bad. Also good to blow away chaff,
especially when combined with tossing in a collender.
Freezer - bag it or whatever and pop in the freezer. I like this one,
especially when I dump from my Alpenrost. 
Dump in SS WOK and hold in ice water. Picks up condensation though. 
Quench with sprayer.    
Toss - Best to get rid of chaff any way. 
Increase time on roaster cooling cycle. 
Insult the wife and let her frigid stare chill the beans... They frost
over then.   :=) 
They all work to a degree.  I like the tossing and blowing cold air the
best.

I put hot beans in a screen colander and place on the downdraft vent of my
JennAir range. Beans cool very quickly due to the forced airflow.

No JennAir here.   I use a shopvac to pull air through the colander of
hot beans when I roast in a popper.

For about the first six months or so I used to toss them in a colander.
Then  a cold cookie sheet.  Then I was home alone and couldn't find my
wife's kitchen stuff so just ran it to the end of the cool cycle and pitched
them into the ceramic jar. I roast light anyway so I guess it improved the
taste - now that's all I do. I guess I'm not as obsessed over this stuff as
I thought.

Steve;
	Go munch on some Dungeness Crab and feel good about where you live.  We're
having trouble at 87 degrees trying to get into a Christmas mood.  I'm not
concerned - the day my son arrives (for the first time) from Kentucky - we
will probably have freezing weather and he'll think his dad has been kidding
him all this time.
John - remembering the rain you can see in Seattle (that's snow y'all)

Hey, remember Grandma's pies on the windowsill? That's where I've been
putting my wire basket of beans, at least this time of year.

I took a computer fan, put some dowels under it as legs.  Made a cone out of
tagboard and attached the small end on top of the fan.  The colander fits on
the top of the cone.  I dump the beans in, the airflow cools them quickly,
and lift off the colander.  It also helps blow any remaining chaff away.
I recently got a stronger fan to handle a full lb of beans. It's 100cfm,
strong enough to cool, but not to agitate a full lb. So I wll have to find a
stronger one at some point.
The fans are around $12, so it's not to bad of an investment.

I agree.  I just let it run to the end of the cool cycle and then toss the
beans into a metal bowl.  I never was able to determine any difference in
taste by cooling them more thoroughly and methodically.  I even tried the
spritzing method when I used a popper; but other than the satisfying sizzle,
I didn't notice any difference.

When I was a bit more obsessed with this stuff, I tried a method of cooling 
whereby I put a piece of wire mesh in the end of one of the segments of a 
vacuum hose. I then just vacuumed up the hot beans and kept them in the 
flow till they were cool. It was interesting that the standard amount of 
beans (80grams) fit the wand exactly.
To help in the cooling, I would sometimes turn off the vacuum and let the 
beans slide out. I would then suck them up again. I did this a few times to 
sort of circulate the beans.Also, the chaff was caught by the mesh screen...
  It worked, but I do just as well aiming a small desk fan at a mesh 
strainer and lifting and dropping the beans with my hand.
Ciao,
Angelo

I know folks have talked about punching holes in dog bowls that are then 
placed over buckets as part of a cooling device. You then punch a hole 
in the bucket so a shop vac nozzle can be inserted to cool the beans. 
One of the problems people have with this is smoothing out the bowl 
afterwards to remove the jagged pieces of metal left in the dog bowl 
after the punching process.
I just tried something a bit different. Instead of starting with a dog 
bowl (or other ss container), I began with a SS  wire strainer. See: http://tinyurl.com/yptmmd. I then took a Phillips head screwdriver, and 
used it to enlarge a bunch of the very small mesh openings, making them 
large enough for chaff to exit, while leaving the beans behind.
It took less than 30 minutes, and works like a charm.

Although news about my bean cooler hasn't exactly thrilled anyone but 
me, I do have pictures. Hope you can see them Carole :).http://coffeecrone.com/roasting/cooling.htmv

Well, Vicki - I just saw your bean cooler, and I think it's pretty - cool.
(Sorry for the bad pun.) No, really - very creative. Love it!

Nice work Vicki!
I alway roast outside but my cooling has gone through a few transformations
and ended up with a very cost effective box fan sitting on a mesh trash can
and a sieve sitting on the fan (blowing chaff all to hell) It is pretty much
like your outside picture.
Nice pictures, way to be resourceful!

As I was surfing around a night or two ago, I came upon someone selling 
a cooling setup for $99 that was basically a more attractive version of 
this using a punched stainless steel bowl as the bean holder. I 
remembered several people writing about how difficult it was to make the 
holes in that kind of bowl, and it occurred to me that if you were using 
a smallish bucket, and limited airflow with a lid, a strainer would be 
waaay easier to work with and would work well.

Nice work Vicki :) Thanks for sharing your endeavors.
How large is your strainer? I was thinking that a SS Colander may also 
work. It already has holes about an eighth inch in it; but there may not 
be enough of them.
Iirc, you normally roast about a pound correct? If so, I am happy to see 
your results as that is how much I usually roast with my PGR.
Still using the hair dryer to cool, but 'thinking about' trying to get 
them cooler faster.
Thanks again,

My colander didn't have the right kind of holes, or at least not enough 
of them in the bottom. I looked at that first. Another colander would 
probably be fine, just not the one I had. The strainer holes are larger, 
btw, than the ones in my colander. The strainer has a 10 inch diameter.
The upward facing fan from the first picture cools the beans faster, I 
think, but I don't really know as I was cooling inside the house, and 
lately, cooling in my garage has been very, very fast.
I normally roast about a pound, but as I didn't really need coffee--just 
needed to try the cooler--I used less for this.
As I said on the page, I did it to see if it would work.  I really do 
like my original cooling apparatus better, and if I had to actually go 
out and buy a shop vac, I would never have tried this one out.

Vickie,
A year or so ago, someone on the list tried using a shop vac for cooling 
and the hose melted.
Not sure what amount of beans he used, but it must have been a bit over 
a pound.
Hope this helps,

I would assume, this if you wanted to get serious about this, you could 
align the vac opening and the bucket opening, and use a connection made 
from a less heat sensitive substance. The big bucks one I saw for $99 
used an inexpensive 2 HP shop vac. My shop vac has a bigger motor (is 
that what the HP refers to). With the more effective suction, the beans 
might not have much contact with the sides of the hose.
As you read this, please know that I am hopeless about all sorts of 
electrical/work shop shtuff. I just get an idea and try it out as best I 
can.

Vicki,
Great ideas.  A possible addition to your cooling system is presented here:

Great cooler, Mike. The basic thing I was trying to do was avoid having 
to punch through stainless steel. I looked through my vac accessories to 
see if I had an attachment that would direct the suction up, rather than 
pulling the air in sideways. I didn't have one that fit at home, but I 
looked through the catalogue and found out that they do make them.
It's interesting (to me anyway) how, over time, and sorta kinda 
independently, folks take the same basic idea and make small changes. 
Some of them are keepers, others simply fade away.
I know that I first started roasting with the unmodified bread 
machine/heat gun combo after reading lots and lots about HG/DB and 
reading and seeing great examples of bread machine/TO roasters. There 
was nothing particularly innovative about what I did, instead it was 
based on choices I made coming out of my inability to do the wiring for 
the latter, and the stirring for the former.
That kind of adaptation seems to come easily to a whole bunch of people 
with disabilities my age, who had to adapt and modify sorta everyday 
things to accommodate the tricks our bodies play on us. I have expensive 
purpose built "dancing" braces for under my keyboard shelf now that they 
are in production, but my first go around was with a big wooden lazy 
susan that I screwed into the bottom of my desk that supported and let 
me pivot my arms when my muscles were too weak to do the job.

I agree, it is a constant source of amazement to me how the simple logical
solution seems to float to the top of the idea pool.
The really attractive thing, to me, about Jim's "Beanie Vac" is the idea of
vacuuming the beans from the roast chamber into the cooling tray without
having to physically manipulate the roaster.  My roaster is a modified
popper with a glass chimney, and not having to pour the beans out into a
cooling aparatus, limits my opportunities for breaking and spilling things.
