Hi everyone,
I am currently running CO2 extractions and winterizing the crude material with 200 proof ethanol at -20oC for 12-24 hours. I am interested in speeding this process up by performing the winterization in a -80oC freezer. Does anyone have any experience with this? Does it speed up the process? I would think that cooling faster would speed up the precipitation of the lipids, but I also know that precipitation/crystallizations are hampered by increased viscosity, and that larger crystals form at a lower viscosity.
Another potential scenario is to use the -80oC freezer to increase the cooling rate, but then filter in stages in order to pull out precipitated lipids, reduce the viscosity of the mixture, and allow the next stage of precipitation to happen more efficiently.
Any insight is appreciated.
Cheers!
