I have a big 2 cylinder air compressor I'm thinking of using. It has an upright 60 gallon pressure tanks, that I think would be an adequate condensor. I'll draw the suction from above the liquid in the fermenter, possibly through another tank(propane) then through the compressor itself, to the pressure tank. I will have one tank under vacuum, and the other pressurized. The vacuum tank(propane tank) should catch mostly water vapor. The rest should condense under pressure in the air tank. Liquids will go to the bottom, and compressed CO2 should remain a gas in the top. The CO2 can be routed back into the fermenter. Any further distilling can be done with either a Potstill or Reflux column.
In my neck of the woods the great outdoors > gets very cold in winter. Enormous heat sink. I'm in Minnesota, so I know what you mean there. It's too cold to start this project this winter. It gets cool enough at night in the summer time. Thanks for your input! Motie ------------------------ Yahoo!
