I started this thread in @DocAnna thread on CO2 collection using balloons. As my approach doesn’t involve balloons I thought I should start my own thread and not high-jack hers!
To recap....
(Edit: lot of talk about CO2 collection using balloons. I'm looking at using rigid containers to capture sufficient gas that can be drawn back into the FV during cold crash and any excess gas is used to displace Starsan solution from a full PB/keg in order to fill PB/Keg with beer O2 free).
So, my Xbeeriment was delayed a few days, but have just been testing first part of my “apparatus”.
Bottom left is FV1 full of water with pump connected to pump water up to FV2 front and centre. The fill speed is controlled by controller on the floor. The FV2 has lid fitted tight and 10mm pipe connects it to the small over-flow jar (tucked behind FV2). From the over-flow jar pipe goes to 5 litre paint kettle which is daisy-chained to the second paint kettle. The 2 kettles are connected using dip tubes that run to their bottom. Kettle 2 is vented to atmosphere.
Kettle 1 is filled (small air space) with water. Pump is turned on to pump water from FV1 to FV2 which displaces the air, simulating CO2 from fermentation. In turn, the air displaces the water from kettle 1 to kettle 2.
When all the water has been transferred, excess gas bubbles through the kettles and vents (phase 2 of the experiment is to connect the vent to a KK full of water to see if enough pressure can be developed to displace the water from the KK).
To simulate cold crashing, the water from FV2 is drained back to FV1 which creates a vacuum in FV2, drawing the gas out of kettle 1 back in to FV2 and the water from kettle 2 back to kettle 1.
