Not sure if anyone else has used this design - came to me in a flash of inspiration. Found the leaf blower on the side of the road - even had an inbuilt speed control...

I just use 2 sieves like the one shown to hold the beans so they dont get blown away and it cools them from roast temp to room temp in about 30 seconds. The only problem is that it sounds like a jet engine.
