I have a 22 qt roaster to poach with. I run it at 155° -160° but I think it gets a lot hotter on the edges ...
I would like to buy a small (and cheap!) thing I can put in the water to keep it circulating and that will keep the temps even. I do stir it occasionally but I think it probably needs to be a constant thing.
Thought about an aquarium pump but suspect the heat would kill it right away.
Also thought about an aquarium aerator but not sure it would mix the water up much.
Ideas or a product for the job?
I built a little aerator today and after some trial and error it works excellent.
Got a small aquarium pump from WalMart for $10 and 4' of 1/4" copper. Made the loop as shown and ran the riser up and over the roaster edge with a 1/4 barb fitting on the tube.
First assembly I drilled a #50 hole ever 1" or so .... WAY too many !!
I soldered half shut ... still way too many.
I soldered them ALL shut and started over, this time with a very small fine point awl. Just a bit bigger than an needle.
I had it on my bench and punched 13 tinny, tinny holes in the assembly; 3 down each long tube and 2 on each side tube. The holes just penetrate the tubing ... not nearly as big as the whole pin shank.
Bingo ... perfect. Creates a lot of action in the water and it is quite uniform.
I have bits down to 0.015" for my model ship building but I don't think you could drill the holes ... too fragile. The punch works effortlessly. The unfortunate part is that I think you would need to use the copper.
However, one could try using a very long water sink supply line. it will take the heat and is soft so it may punch easily as well.
