Bay Area 11 Girl Scout Cookies x Fire OG
Full nug run, 30 psi tapered down to 0 psi for active pass.
Dry Ice in the jacketed sleeve on material tube for sub-zero temperatures.
Dry Ice in the sleeve on winterizing column with 73u filter for dewaxing.
I packed the tube, with force - but not all my strength (roughly 20 pounds of pressure).
Once the tube is packed and the Closed Loop System is all buttoned up, I start to vacuum the atmospheric pressure down to -30hg within the system.
Once deep vacuum is achieved, I make sure all valves are closed. I then open the gas valve on the Refrigerant recovery tank - which is filled with a hydrocarbon - typically n-butane. I open all the subsequent valves up to the top fill portion of the material chamber. (I use a bi-directional system - which allows both a top feed and bottom feed of solvent, I now only use the top feed for personal preference). I don't use a soak time anymore, as soon as the butane is pumping into the material column - I crank open the valve into the collection chamber and let the juices flow.
From there it's just recovering the butane and dumping the un-purged oil onto a sheet of parchment for the vacuum purge.
