Hoping this is the appropriate forum for musing about a Better Bucket Cooler.
In the immortal words of the Lolrus -- I haz a bucket. I roast about a pound of beanz at a go, and cool them using a Home Depot bucket with the upper half of a double boiler mounted in the bucket lid and a very old canister vacuum with the hose jammed into the side of the bucket.
The result isn't as fast a cool-down as I would like, and it leaves the vacuum smelling of stale coffee, so I'm kicking around ways of improving the thing.
The first idea I had was to use a leftover bathroom ceiling fan, but the thing only moves about 50 CFM and I kinda doubt that's any improvement over the vacuum cleaner (quieter though).
I've looked around for a duct fan, but it looks like the people selling them are purposing them for "greenhouse" use ... and charging accordingly. (Yes, that's a euphemism, at least Out Here.)
The latest notion I had was to throw a computer PS into the bucket and use it to power four or five 120mm case fans. From what I've been reading, some of these shift around 80 CFM, and computer surplus gear is in abundance Out Here.
Any thoughts on whether this would (or even just might) work? I'm too ignorant of fans and vacuums and such to be able to make a smart guess.
