Topic: Turbo Bean Cooler & Chaff Remover (4 msgs / 97 lines)
1) From: Jerry Procopio
When I got my RK Drum in June, I quickly discovered that I needed to 
improve my cooling process.  I built my first version of the Turbo Bean 
Cooler & Chaff Remover.  It's a 1620cfm attic fan (from Lowes) mounted 
inside two DHL shipping boxes with a wire basket (from Bed Bath & 
Beyond)that fits into a hole in the top.
I forgot it out one night and the boxes got rain soaked and lost their 
stiffness on one side and became lopsided.  I've been telling myself 
that I am going to shift from cardboard to wood, but haven't found the 
time to mess with it.  Today I decided to rebuild the Turbo Bean Cooler 
& Chaff Remover with two new DHL boxes (I have an account with them so I 
get them free) and make a few minor improvements over the original model.
If you would like to see a photo of the Turbo Bean Cooler & Chaff 
Remover and some step-by-step construction photos, I have them posted 
at:http://turbobeancooler.freehosting.net/The high powered fan really sucks air through the beans.  It will cool a 
full load from the RK Drum (4 pounds) in less than 2 minutes.  A bonus 
is that by pulling the wire basket out of the hole that it sets in and 
turning the fan box onto it's side and placing the basket over the 
exhaust hole, the fan instantly becomes a chaff remover.  It blows the 
chaff all over the place, but will remove chaff from 4 pounds of fresh 
roast in about 30 seconds or so.
I have a total of about $75 invested.  The wire basket was $10, the fan 
less than $50.  Contact paper and electrical parts comprise the 
remainder.  All parts were new.  One could probably do the same for less 
money using used components.

Nice setup!  Why not start just out with the air blowing up thru the
beans?  That way there would be no need to turn the box over on its side fo=

the chaff removal.

The "chaff Remover" was an afterthought and I didn't really consider 
changing the basic design when I rebuilt it yeesterday.  I suppose 
reversing the fan would work.  I may try that next rebuild.  Thanks for 
the idea.

Or, wire the fan motor so that you can switch it from intake to =

for $10 at local Goodwill. I took off all the "protective?"grillwork for =
more air flow, and also to allow the chaff to exit without getting =
caught on it. 
This fan has an intake/exhaust switch, which allows me to cool my beans =
when they are finished. 
The switch seems to just reverse the polarity of the motor...
A+
