High capacity butane extraction

…Damn, so it would take that much…

I have bookmarks of when I was looking into getting refrigerant equipment to attempt something of the same for a recirculation idea.

Sick shit that you pulled it off.

I mean for the single step thing yes. It depends on op’s clients and if it’s going to edibles or smoking… So dewaxing w/powders is subjective. Dewaxing with cold temperatures seems almost always good enough if the material is fresh. If it’s shit material, then crc it. If it’s fresh then just subzero temp dewaxing at a low micron is good enough.

The COAs looked good, but I couldn’t tell you the exact water ppm off hand. The amount of water I get out of the traps regularly rules out it coming from the butane. I would imagine the dip tubes are brass. What effect would that have? The biggest issue I had with the 70/30 mix was the pressure change during distillation. At this point I would say that butane propane mix form an zeotropic mixture.

Thank you. The current setup I have can run 25 tons at 35°F evaporator temperature. I’m limited by the power supply at 75kva for the whole system.

Very impressive dude! Those numbers are great!

Biggest hydrocarbon system I’ve seen in person was the behemoth from Illuminated. This was about 2 years ago so I’m sure @Zack_illuminated has changed plenty on the machine especially with the pro jak system being implemented. Without the jacketing system we were able to hit between 700 and 1000 pounds per 12 hours depending on material pack.

Thank you. I wish I could put up more pictures. I don’t use a column or pack the material. With one person running it I can do about 2100 lbs in 12 hours. With more power available it will do 3000 lbs in the same time. Have you seen any other systems that does it this way?

The only machines I’ve seen approaching your throughput with a single operator are ethanol skids and GIANT multi million dollar co2 machines. We had 3 full time sock packers to handle the 150-200 socks needed per day and took 2-3 people to efficiently run the extractor.

That’s dope, it might be about as big as my whole lab. Is that the hopper on the right side? How are you introducing butane into the auger? In my experience hitting the material with twice as much fresh solvent has resulted in a more thorough extraction so I would think that slowing your auger speed would pull more CBD out if the butane is constantly flowing through the auger.

Thanks. Yes that is the inlet hopper on the right. The butane sprays in on top of the biomass at the start of the auger. It then soak the biomass as it moved along the auger. The butane flows co-currently with the biomass. I currently run 8:1 butane biomass ratio. There is also a 30 second fresh solvent rinse. I have tried different soak times between 5 to 20 minutes and it doesn’t seem to make a big difference.

It looks like the auger is horizontal? What is the pressure inside the auger while it is running? What temperature is the plant material when it enters the system and where is your thermometer that tells you the extraction temperature? I’m wondering what the vapor:liquid ratio is inside that chamber during the extraction process. Is your biomass whole plant or just branches without the main stem? I’m assuming it is outdoor hemp that isn’t defoliated prior to harvest at your scale.

Sorry for all the questions but I’ve never seen a truly continuous extraction system like this for butane and I love the concept.

I’ll dm you later.
