I know it’s always been said that you have to winterize before distillation, especially hydrocarbon extract. I’ve done it without winterizing in the past and my disty always went cloudy after cooling.
Why, then, can I now get disty in a single pass on a 2" pope that looks like this without using ethanol? This isn’t a brag, I’m genuinely curious. I’m not saying this is fat/lipid free. In fact I’m sure there are still a few lipids present, but obviously not enough to cloud the distillate.
@spdking made up winterization to sell more pig filters and expensive filter paper, the rest of the industry gear guys caught on and used the myth to sell everyone giant rotovaps and filling films and chest freezers etc
If you are maintaining those cold parameters your initial extraction is selective enough to leave out the fats and lipid compounds that would need filtered out
It’s not that hot, I’m still running plain water in my condenser. Been thinking about switching to a pg blend to go hotter but haven’t yet.
I will say that I’ve only tested non dewaxed/winterized material in the past that was extracted with solvent warmer than -40, so that indeed may be the ‘good enough’ point.
even releasing 200PSI air from your solvent tank will cause the outlet to frost over.
yes, @PharmExOregon is correct, you really should know wtf you’re doing if you’re gonna use evaporative cooling to chill any part of your system…and @FicklePickle is also correct, it is a trick the pros use.
I for instance have run a couple of lbs of solvent into my vacuum jacketed columns and recovered that to chill them down before filling and soaking. I used the head pressure I gained by recovering to push the -70 solvent (no head pressure) out of my solvent tank.
