So... who said you need to winterize?

It has been my hunch for a long time that cold propane picks up significantly less fats than cold butane.

I think it probably has to do with the smaller size and surface area of the molecule effecting the London Dispersion force.

The very few times I have ran crude in my propane system there were hardly any fats at all when the extract was redissolved in etOH and chilled.

I was using decent quality crude trim though, not garbage.

It would be interesting to see a controlled side-by-side test for fat content with the same input material and extraction parameters but the only difference was butane vs. propane.

I am a big propane fan and I honestly don’t understand why people use butane over propane.

So many advantages to propane.

In my limited experience with propane, it’s much less effective at grabbing cannabinoids, probably for the same reason it leaves behind fats.

I’ve yet to find the magic ratio between butane and propane that maximizes cannabinoid extraction without pulling fats, but we’re working on it. Also want to try straight ISO for the same purpose.

Hi @Tech1145 HNY,
Can u tell us more about your liquid separator please? How is it constructed? I wanna try it in lieu of a sieve.

Mod edit: see Liquid separator instead of molecular sieve
