Setting up our equipment for our nano brewery to be ready to sell by june, all is going well. I know inline carbing has been covered many times and I also read all the posts about it. Thing is, we are fermenting and conditioning our beers in 240gal plastic conicals. we got our hands on a 400gal brite tank single wall which we will use for our bottling/kegging tank since plastic conicals cannot hold pressure. We were going to go with 17-1815.5 gal kegs and carb them one by one until we got our hands on this 400gal for 2000$... 3 months old.
So, thinking about my carbing process and how to relate to how I've been doing it for over a thousand of gallons at the home brewer level, I use an HDP Carbonator, which simply recirc the beer from the keg goes through an inline C02 stone and back back in the keg for several minutes (about 7 usually), that works great... for 5gal.
Now, with that 400 gal I thought of adding an inline stone on a T with a sight glass and use our brewery pump to recirc the beer and carb it up. The bottom of this 400 gal tank as 2 1.5 TC connection, one at the very bottom (drain) and one at the 20gal mark. As many mentioned they bleed off the CIP, when relating to the HDP Carbonator, we never bleed the "excess" pressure, it simply recircs.
You guys think it would work the way I plan it? I know it will take more time but I do think it will work. Of course one way to find out is to try it but this will be our inaugural batch, I rather get some feedback prior
Also, one more question. Since our fermenters have 240gal and our bottling tank is 400gal, what if we don't fill it up completely? it will happen for sure. filling the headpsace with C02 will cost an arm and a leg just to fill our bottles. Could I get an inline air filter (same as divers use) and fill the headpace with air instead? Although I worry about oxidation.
Perhaps we'll have to make it so we fill it up all the time, which is doable, although it would mean mixing 2 batch together.
Thanks in advance for all your tips and guidance!
