Normally I aerate my wort by splashing it when transfering from my no chill vessels to my fermentors, so I understand that I am mixing my wort to the air and all the microorganisms around when I'm doing that. Before splash I put my yeast in the bottom of the fermentor and the same movement mix them to wort to.
Now I want to No Chill and ferment in the same kegs. Is it possible? How to properly aerate the wort doing this way? I know that I can simple shake the kegs to aerate them, but these kegs don't seal if they're not pressurized. So it will be a big mess to clean if I need to do that way. And a O2 tank is not a possibility for now.
So I want to know if I can:
1) Fill the kegs and seal them with CO2 to No Chill;
2) Pitch my yeast directly in these cornys after chilled, put some CO2 to seal it, shake it to mix the yeast to the wort;
3) Remove the gas in post to hook a hose as a blowoff tube, plug a bicycle pump in my liquid-out disconnect to aerate the wort.
This protocol seems good? There is a better/safer way to do that? It will be better if I use the same HDPE vessels for no chill and splash it to the cornys? A bike pump is better/worse than a aquarium air pump or should I expect similar results? I've been reading a post about aeration and this answer caught my attention. Could I get some good If I use a kitchen mixer to mix the yeast and aerate the wort?
Thanks a lot again. Sorry if it seems to much questions inside just one.
