How do you cool your beans?

I use to use a dust extractor, flexi duct, a cardboard box (bigger enough to house a stainless steel sieve cut in the top). I would seal the box and sieve with duct tape, duct would go from dust extractor to cardboard box which i would also seal off with tape.
Pour the beans onto the sieve after roasting and turn the dust extractor on and stir a few times. Cools down in about a 1-1:30min.
This was cooling 2kg of coffee.
Worked effectively

I press cool on the behmor and crack open the door! :-)
Previously had a stainless sieve sitting in a bathroom extraction fan (sucking air).
Prior to that I had a garden blower vac. Cut down the suction tube, cut a hole in a bucket to suit and placed a sieve inside the bucket. Cooled them in less than a minute. Bloody noisy though! And once the sieve moved and it sucked in some if the beans, sprayed the garage with grounds!!!
Cheers

40cm baker's sieve that sits inside a plastic plant pot with a bathroom exhaust fan below the sieve to sucks air through the roast.
It was almost as if the plant pot was designed to hold the sieve. It has an inside diameter slightly larger than the sieve and a ridge that runs just below the rim of the pot that the sieve sits neatly on. Works brilliantly to cool the beans in about 2 mins.

Mal.
My cooler is a 20 liter bucket with grading sieve using an exhaust fan, cools real fast and like Mal's, barely audible.
First posted details with pics on Coffee Snobs about 7 years ago.
