Bucket Tek (Cold Ethanol Extraction on a Budget)

diy

#1

This is the SOP for how we got started. Big thanks to Pharmer Joe Oakes and Photon for helping lock this down back in the day.

1.Determine initial volume of Ethanol based on flower volume (1L of EtOH : 2L Flower) Divide flower volume by 4-6 (depending on flower quality, 4 for high quality 6 for low quality) to determine batch size. Ex: 20lbs / 4 = 5 batches, 4lbs each.
2. Prepare Volume of EtOH by pouring total volume into “Chilling Bucket” (No more than ½ way full)
3. Slowly add dry ice to EtOH until temperature is -50C or colder (Throughout process continuously monitor temperature, add dry ice to maintain -45C to -50C
4. Fill “Extraction Bucket #1” ¾ way with flower to be extracted
5. Pour chilled EtOH from “Chilling Bucket” to “Extraction Bucket #1” until flower is submerged
6. Let soak for minimum 10 minutes
7. Fill “Extraction Bucket #2” ¾ way with flower to be extracted
8. Pour partially saturated EtOH from “Extraction Bucket #1” over flower in “Extraction Bucket #2” (This will not be enough EtOH to fully submerge flower in “Extraction Bucket #2”)
9. Pour EtOH from “Chilling Bucket” over flower in “Extraction Bucket #2” until fully submerged
10. Let soak for minimum 10 minutes
11. Remove flower from “Extraction Bucket #1” and place in centrifuge to dry
12. Fill “Extraction Bucket #1” ¾ way with flower to be extracted
13. Pour partially saturated EtOH from “Extraction Bucket #2” over flower in “Extraction Bucket #1” (This will not be enough EtOH to fully submerge flower in “Extraction Bucket #1”)
14. Pour chilled EtOH from “Chilling Bucket” to “Extraction Bucket #1” until flower is submerged
15. Let soak for minimum 10 minutes
16. Remove flower from “Extraction Bucket #2” and place in centrifuge to dry
17. Repeat steps 4-16 until initial volume of flower has been washed
18. Proceed to SOP #2 Carbon Scrub

Attached is the complete SOP in my standard form

Very clearly worded with precise directions. Love the idea of an extraction on a budget series


#3

I’m actually trying to work out the cheapest/ easiest way for people in rural areas to be able to make full spectrum oil, from very low quality, seeded weed. So this extraction on a budget is a great idea.


#4

Ditch weed eho!


#5

Now I know eho is great way to extract, but out where I am going, in the mountains, there isnt eho. Gotta think real basic. Maybe something like butter? This is Africa we talking about.


#6

Hashish! We need Frenchie canoli(sp?) over here


#7

What kind of centrifuge are you using for large batches? How many rpm etc


#8

Washing machine, Hobart salad spinner, UsFiltermaxx centrifuge

rosin seems to fit. u can explain it in 2 words. Heat’n Squeeze
plus u can build one anywhere u can find a harbor frieght


#13

Doubt there’s a harbor freight in the hills of rural Africa…


#14

No electricity in the mountains and I’m trying to get a full spectrum oil to them.


#15

What about sifting, or bubble hash? It’s has literally been around for ever. Or in Nepal when the native people make “charas” they do so by rubbing the flowering plants between their hands. Then they use their thumb to collect and ball up the resin off their free hand. This way of hash making is very old. This sift can be your starting product and a great way to cut down the bulk .


#16

what other types of extracts r full spectrum to you?
then ethanol is the only choice. if dry sift isnt full spectrum
even hash will be super hard cause without electricity u cant get ice. ice is harder to make then ethanol lol it can be grown anywhere on the planet from anything with sugar, it can be purified by simple methods
I use to work at a brewer’s supply store and taught people to make beer and making alcohol is ridiculously easy to make. u can literally make ethanol by chewing up fruits and spitting them into a jar

So what I want to try to achieve is to give them a liquid based solution. Something that is convenient to ingest and easy to make.
Some of the village elders won’t smoke or be seen smoking so I want to avoid them having to smoke it unless it calls for it ie; lung issues.
The dry sift is an option, but if a screen breaks then that’s goodbye to that.
The alcohol is definitely an option, they make there own home beer, but its just fermented maize. I guess it would have to be refined a bit more to make an efficient extraction solvent. There is plenty of smirnoff vodka around???


#18

If this is for oral medication I think the best simple option is just extract with lipids. Basically like making cannabutter, so easy every kitchen could produce it.I feel this is the best option in light of the method of use.


#19

Definitely. A warm butter extract? Not gonna taste good at all, but definitely get them high.

Another possibility would be a high pH water extraction, which if then brought back down to a low pH will crash THCa out. Not super efficient with jungle Tek, but doable. I’m sure there’s plenty of native plants that can swing the pH. Down is easy, oxalic acid is probably in some of the local plants, pHing well water up past 10 might require some ingenuity


#20

This is probably gonna be the best way. Taste isn’t an issue and butter is available in the town and it is easy to make with no KABOOM.


#21

Just to be clear, a cooking oil would probably be preferable do to it’s liquid nature at lower temps, I was just trying to think of something widely available
