I was wondering if anyone had ever attached a small paddle to a motor to sit over the top of the kettle and stir/form a whirlpool while chilling?
I've kicked an idea like that around in my head from time to time. Need to address issues like avoiding aeration when it's still too hot, making sure no 'motor goop' (lubricants, etc.) drips into the wort, etc. Never have gotten around to actually doing anything, though.
I feel like I've seen someone build something like this on some forum somewhere. I envision a small paddle on a central shaft attached to a motor either directly or by belt all mounted on a frame that sits over the kettle. Seems like it would be a fun thing to try and build but that being said it might be a lot easier to just buy a pump and recirculate to make the whirlpool....
