making ethanol oil

102 posts in this topic

Out of interest Graywolf, are there any like small scale commercial units you recommend or have had experience with? I'm looking to guerilla grow some high CBD hemp and so have been looking at the best way to maximise what i get out of it! There's so many on the market (a lot US based) with so few reviews, it's hard to judge.

 

Cheers

Because there were no units available when I started, I designed most of my own equipment, and favor their design.  For BHO, I designed the Terpenator and Lil Terp series, which you can build your own, or I suggest checking out Terpp Extractors, or Best Value Vacuum.

QWET is my other favorite process, for which I designed a simple recovery still, as well as a rotary evaporator, but no one built them commercially, and other designs are readily available built by others.  I personally like the the Heidolph rotary evaporators.

Thanks a lot Graywolf. Just getting into the extraction side of things and seeing your name everywhere! Found some really useful info on future4200 as well.

90% of my bud goes to making oil and I vape the rest

 

Could  I skip the drying process if I am decarbing in the oven 1st ? (oven drying in real life :chains:)

This way I could have my oil week earlier

We've oven dried at 200F, and then decarboxylated the oil afterwards at 250F in a hot oil bath. 

 

I much prefer to decarboxylate the oil, than the plant matter, because you can tell by the CO2 bubble production precisely where you are.

 

What I rather do, is freeze fresh cut material and the solvent to -18C/0F or below (<-30C preferred), for the extraction, so no drying is required.

@Graywolf

 

thanks for your input,very much appreciate it.

 

I will do my next one from frozen -only a batch to compare the yields (at the moment i am getting 3.5g from an oz  )

 

however i can see this as a great potential for outdoor growers who might not have space for drying their crop :yep:

The simplest is to pour it in a shallow dish, like a pie plate or casserole dish, cover with a cloth to keep out dust and pet hairs, and let evaporate.

You can speed it up with a fan, but may pickup atmospheric humidity.

Faster on a 135F heating pad.

You can also boil off, or distill off the ethanol.

@bazil brush as it's alcohol any well ventilated area is fine.

 

I use 99% iso indoors, with ventilation (bathroom extractor in my workshop), in a "bath" to clean circuit boards for around 20 years now with no accidents other than the odd spillage which evaporates quickly.

Outdoors is always better if you don't have an extraction hood.

 

Conflagration requires a flammable within explosive limits, oxygen, and an ignition source.  We can control concentration with ventilation and of course limit ignition sources.

 

Ethanol's Lower Explosive limit is about 3.3% which an open window with a good fan can stay below.   https://www.afcintl.com/pdfs/applications/combustibles.pdf

 

In perspective, this is the alcohol that we use for flambe cooking, but consider how serious it would be if you dropped and broke a half gallon of ethanol and it not only flowed across the floor, but ignited.

 

Always have a Plan B, that includes a fire extinguisher.............
