I won't dwell because I don't write well in English.
What I want to achieve is to recycle CO2 from fermentation, compress it at low pressure because I haven't the skill lo liquefy it (let's say 6-7 bar), and store for further usage.
I intend to use cheap materials like pet bottles, fast compressed air junctions, a 12v "oil less" compressor (air smells a little so not truly oilless i fear) and a PC power source.
The core of the system is an heat sealed plastic food bag which takes an input from my fermzilla spunding valve (In the photo the CO2 cylinder simulates a fermzilla). Inside the bag there's the little 12v compressor that push co2 outside the bag into the storage system.
After the gas comes out of the bag under pressure, It will pass throug a non-return valve, a pressure gauge, a tank (PET bottles), a faucet (gas outlet).
Initial tests show that the system is airtight (but it was no easy task to make airtight caps due to washers too soft and wavy caps).
The next step will be to add some controls to detect when the bag gets full and the compressor needs to be turned on. I'm thinking of a potentiometer that can sense the width of the bag and activate (via an esp32) the compressor until the bag returns to its previous state.
Any help/thoughts will be appreciated, bye,
