Lately, I’ve been wanting to go BIG... need to extract at least 200lbs of material per run.

Was thinking about buying a large commercial washing machine, filling it with Trim, hooking the water line up to an ethanol tank, and set her to heavy wash.

Any flaws in my plan?

Build a large screen with multiple layers. When the rinse cycle is done. It may shoot out fairly quickly. Exciting. Good luck

Why not use water and ice and do bubblehash in the washing machine? Then you don't have to evaporate ethanol, u just dry out your hash and it's ready. Also, if using ethanol u need to make sure it won't effect the washing machine parts (rubber seals ect.) or extract nasties like lubricants or other shit from exposed washing machine parts.

Ummmm, large commercial washing machines aren't designed to run flammable solvents, so hoses and seals are unlikely to be compatible. Not only might they fail, but they will leach constituents into the alcohol.

They aren't NEMA 7, so a leak could equal a fire.

Unless you were controlling the temperature, you would most likely end up with chlorophyll soup.

We've run ice water in our washer and extracted the kif with ethanol afterwards, which works well except for the lower yield part. We get more usable produce just doing a QWET extraction.

Some component of the washing machine disintegrating after being exposed to that much solvent or a fire would probably be your chief worries. To do 200lbs of trim you'd probably need something with a 60-80 cubic foot capacity at least, would take about 3,000lbs of ethanol to fill it. Can you lift a 3,000lb bottle of Everclear?

ptfe or other food grade trashcans plumbed to a filter plate.

I tumble the material and then soak it in ethanol, in the freezer. I do two tumbles one for 3 min for rosin, and the around 20 min for the ethanol material. You may not get all of the product, but it is not as green and takes way less ethanol...

1) Completely disassemble, examine, and reassemble with only the basic plumbing and wiring necessary. Upgrade the plumbing pieces that don't pass a leach test. Replace or seal up any control switches, solenoids, temperature limit devices, etc. that may be possible ignition sources.

2) Screen the tub, or place the material in filter socks. If you screen the tub, the material should end up as a dry cake lining the inner circumference of the tub that you can scrape out in chunks. A large sheet of stainless steel mesh could be long set epoxied in place to cover most of the tubs holes, another ring of SS mesh epoxied in place at the bottom of the tub to cover those holes.


Because you're able to centrifugally remove the solvent the process should be extremely efficient. You could even spray rinse while it's spinning after the primary wash.


Run chilled ethanol, or if you've got crazy ass balls run a non-polar solvent.


Here's some pictures and description of how I modded a water distiller for flammable solvent use. J-B Weld is your friend.

Thanks for the inquiry, on track with my imagining a washing machine extractor combined with a commercial solvent recycler.

Doesn't Delta Separations build exactly this with the appropriate parts? Bit pricey.

Instead of running one large machine, why not use several smaller machines and do smaller batches?
