I also suspect that a cryo mech would speed recovery. Hmmm...

For example, Limonene would predictably wash above -101f. Once the sweet spots for each terpene to be extracted is determined, its just a matter of choosing wash points based on goals...

A "Cold Fractional Extraction"

Sorta thinking propane for the coldest washes.

Ok, so we know that with apparatus such as a rotovap using vacuum and heat one can relatively selectively boil off terpenes, thus fractionally distilling a concentrate. What say we flip this upside down. We go to cryo temps of -170f, hypothetically locking up all / most compounds, then each...

now there's a new industry, pot insurance. Lol

So get one. :)

Yeah if you chamber it too early not only are you putting excess solvent in your pump oil, you risk a boil over.

Then they would make it harder to purchase the tane and not equipment that could be sold as "not intended for use with butane or propane". Possible unintended consequence, street values go up, incentivizing the market.

There's other oils, from other plants. So products could be marketed as such and not tied to pot.

Commercial extraction is the key phrase. Also Denver is one city. The fact the state DA says there is no protection for doing such simply says it's ok to make any local ordinance prohibiting said process outside of the regulated, taxed, MIP licensed environment.

Imma bet "essential oil extractor" or some similar lingo....

This is the AG, not a committee.

From my understanding the AG references A64 (rec) when he states that it doesn't allow for home production period. Keep in mind, the uneducated see the closed loop much like a bomb as they fail to grasp how difficult combustion is sans oxygen inside the unit. Wonder if medical has more...

And perhaps therein lies the problem? Or to put it bluntly, ignorance is bliss?

Skip the heat, put a screen on it like for a skillet on the stove and a fan blowing air over it. More surface area is better as the thick oil is spread thin so as to avoid trapping solvent.

Hmmmm... Will this drive bhotards indoors thus exacerbating the issue?

Depends on thickness /area of film, air circulation, humidity and how much solvent was used. 24 - 48 hrs is typical.
