@pdxcanna it doesn’t look like its boiling at all, it looks like a fan is blowing on a dilute solution.
A buane solution tends to make kind of a mess on the sides of the dish its evaporated in, even before fully reaching saturation. That’s what really convinced me its an ethanol solution. But I’m wrong all the time lol.
You’re getting a foam every time because propane boils off at -42c, so as soon as you open your spout to dump your oil the propane vaporizes at atmospheric pressure and ambient temp, you’ll get a foam or cheeto puffs. 70/30 B/P will definitely come out a liquid tho.
If you switched to 70/30 it should work much better . Alternatively you could take nbutane and inject 1lb of it into your collection chamber before you dump your column so at the end of recovery all of your PHO will be dissolved in the 1lb of nbutane for your pour so you will not run into this foam issue . While purging use the least amount of heat and low vac between -10 -15 HG to purge sauce fraction or it will turn more into a jelly consistancy
Couldn’t be bothered scrolling to reply to OP (but they get notifications anyway, on all replies to their thread).
Had I been replying to @og_extracts I might have pointed out that if one understands the relationship between pressure/phase change/temperature then one wouldn’t necessarily need that freezer…
