Extraction Pr0n - The Terpenator Essential Oil Extractor

Hit a new record for our machine this past week. 12% return by weight (on small bud laden trim) after winterization. Made a real pretty absolute amber that looks just like the above photo and tested at 78%+ THC and 80%+ total cannabinoids. The leftovers, as usual, tested at less than 1% THC.

:drinking-coffee:

We've also streamlined the process a bit and we can now do our initial extraction in about 45 minutes and we've gotten the winterization/filtration step down to about an hour. Purging the winterizing solvent has also been streamlined making it quite easy to knock down 15 ounces to absolute amber in a few hours.

 

AA works great for 'dabs' on a nail, skillet, wand, etc and also is great in an omicron/o-phos/persei or similar personal vape pens.

We added a new process step this week that allows us to process powdery mildew and botrytis infected cannabis and remove the mold spores that negatively effect the flavor of vaporized oil and can be so troublesome to some patients with allergies and weakened immune systems.

 

Some simple 50ml syringes and 0.22 micron syringe filters are all that is required. We dissolve the extract out of the pressure pot with a solvent, winterize to remove the non-polar waxes, then filter the winterized solution through the syringe filters to remove the mold spores.

 

It seems to work well with a 10:1 solvent to extract ratio by volume. We obviously have to estimate this, so we overestimate it to make sure we've got the solution thin enough to make syringe filtering a bit easier.

 

This is only suitable for material that had mold growing on living plant material, as those types of molds do not produce harmful mycotoxins. If the mold grew on dead material, this technique will NOT remove any harmful mycotoxins produced by that mold from the extract.

What is winterization?

What is winterization?

 

When you perform a butane extraction, you extract non polar waxes, lipids, and fats along wth cannabinoids. To remove the waxes etc, you dissolve the BHO in another, less non-polar solvent like 190 everclear, acetone, or isopropyl alcohol and chill in the freezer until the waxes drop out of solution. Once they're out of solution, they can be removed through simple filtering. Once filtering is completed, the second solvent is removed using agitation, gentle heat, and hard vacuum.

 

It's called winterizing due to the trip to the freezer.

Is there any real reason to remove the waxes? Another question.....Have you ever decarbed the starting material before doing a butane extraction so it (BHO) can be eaten like it is? HJ

 

For smoking it makes for a somewhat cleaner product. I have also heard - though not confirmed - reports of people smoking significant amounts of unwinterized BHO getting a waxy deposit in their lungs. I don't think people want to smoke wax if they don't have to and would rather not risk it.

 

If it's intended solely for eating, it's not really necessary to winterize, IMO.

 

I have attempted to decarb before extraction, but my oven doesn't hold a very tight temp so we end up vaporzing some in the oven.

 

I prefer to decarb in a hot oil bath post extraction. It's easier to control the temp and monitor the extract.

well, almost complete. i want an inspection port for the bottom, lab hotplate, a nice vacuum pump and a couple hoses.

thinking a wheeled cart/stand for easier transport/setup may be in the future
