For cool down I dump a finished roast into an old wire mesh colander, then pour it into another old wire mesh colander in front of my stand fan on high speed, repeatedly between the two. This removes what little chaff is left from air popper and does a relatively quick cool down. This is then poured into a large SS perforated colander and repeated until all roasted. I agitate the large colander to mix the cooler and warmer batches. After last roast I dump the large colander into one of the old wire mesh ones, again in front of fan, several times. Put away gear and by this time beans down to ambient and placed in my crock containers to degas for day or two.
I've had to patch both my old wire mesh (like screen wire) colanders as I've been unable to find anyone that makes them any longer. All I find now are the perforated metal or plastic units and they just aren't up to the task IMHO for rapid cool down. The wire mesh that I have found (and have a set) isn't as heavy duty as my 30-40 yo ones.
