Hey everyone, SWIM extracted his
first BHO using an open loop system about 36 hours ago.
SWIM don’t have a vacuum, so he decided to heat purge.
SWIM started by heating the extract in a water bath, then added ethanol, and now it’s in a vegetable oil bath (the oil temperature is around 100-120°C). After 24 hours of heating the extract at around 80-120°C, SWIM noticed that when he use a thermometer to measure the temperature of the extract (BHO), it doesn’t go above 66-72°C.
Is there still solvent in the extract? Is it normal for the purge to take this long? How long more usaully take? any experience?
( Over 24hrs in veg oil around 100-120c ).
For reference, SWIM extracted around 500 grams of trim and got about 50 grams of crude oil u til now.
PS: SWIM don’t care about terpenes; He just want to fully purge the solvent.!
Hey,
So the thermometer that is in the hash might not be immersed deeply enough, this can cause the thermometer to read incorrectly. This would be my first guess, you could relay to the person who isn’t you…
Next time just place in a double Pyrex arrangement with boiling water poured into the lower Pyrex once all of the solvent has initially evaporated. you can pop any bubbles with a dab tool. that was the standard early 2000’s tek.
Swim sounds doomed. A 10% return on trim sounds a bit too good to be true. I imagine there is a lot of solvent still in there. How is the oil? Consistency, viscosity, odor, how does it cling to the sides of the glass vessel when you move it around, is it still bubbling?
he says there’s no bubble left. It wasn’t just trimmed leaves; he also mentioned there were also many small flowers mixed in.
SWIM says they ended up with 42g.
Winterizing BHO isn’t a horrible idea, but just adding a solvent that boils 70C warmer than the solvent one is trying to purge, for no reason at all, would generally be considered a bone-headed move…
Brother if you held your BHO extract at 120C/248F for 24 hours and are bubble free, you are ostensibly both purged of butane and decarboxylated. That is how we purged in he hoary days of yore before vacuum.
The other way we did it has already been mentioned, and that is to winterize with ethanol and removing the ethanol also removes the residual butane.
@Graywolf. I was remarking on the original posting that stated “SWIM extracted his first BHO using an open loop system”. I understand closed loop blasting & open blasting but I’ve never heard of open loop blasting. Made me curious.
