CRC taste like shit change my mind

Passing thru a layer of neutral ph media at the end would help fix it. Might save our terps too during recovery

Alcohol allows you to see and residue fare better than butane .

Dred_pirate · September 28, 2020, 4:41pm

Elaborate on this

Waxplug1 · September 28, 2020, 4:41pm

the real issue is what to do with all our spent medias
Im thinking about picking pottery up as a hobby

This one certainly lists the correct way to set up a filtration over magic dirt…

TheLostBiologist Bucket and Post Processing Tek for Golden Extract

Now, for the pour-- Get the slurry in your bucket very well agitated and flowing then quickly dump the slurry into the buchner on top of the filter paper. Use a bit of reserve ethanol to rinse out the remaining bentonite and dump it right into the buchner as well. You will get a bunch of bypass when you first pour. The reality is that even with a paper filter the clay is so fine that it will pass through. You basically need to overwhelm the filter with clay so that it backs up enough that the clay builds up on top. Then it becomes self-filtering. Once you’ve set a good bentonite cake use the same ethanol and bucket to make an AC slurry and repeat the process. If your bentonite cake is solid then you should see no AC in the vacuum flask. You want to use enough AC that it makes approximately 1/8th to 1/4 inch layer on top the bentonite. You can use more and go thicker to gain longevity with the filter, but you will lose speed and increase the time your extract spends in contact with the AC. I usually pour the same ethanol twice for the bentonite then again for the AC. The first pour is muddy brown, the second pour is cloudy, and the final pour is crystal clear. Once it comes out clear I leave the pump on for an hour or so to dry out and firm up the cake.

Which is the way they teach it in chemistry classes last time I checked (admittedly more than 30 years ago).

Nice find. Yes some talk about it but like I said most do not and that’s all I’m trying to fix. Prewash your media folks

Waxplug1 · September 28, 2020, 4:47pm

What if you add one of these at the very end to catch anything that makes it past the 1micron

ExTek90 · September 28, 2020, 4:50pm

What if you don’t use acid activated media?

Distillforeal · September 28, 2020, 4:50pm

Idk I haven’t experimented with it. But If the residues is from the acid activation idk if that would help

Distillforeal · September 28, 2020, 4:51pm

Washing celite 545 I’ve turned ethonal hazy as well so idk

G_Boe · September 28, 2020, 4:58pm

When setting a Buchner filter, you can get powder pulling through making it hazy, but repeatedly moving the same ethanol through the filter will set the filter so that nothing more comes through. You could it to come through clean the first time if your filter at the bottom had fine enough pores.

A proper CRC should either have a fine enough sintered disk at the bottom to keep any solids from moving through, or a staged filter that would do the same.

Ultra-Fine particulate making it into a final product, in an amount that is not even visible, should not worry you. Breathing the air in Cali right now is going to pose more of a harm.

Nothing wrong with that goal.

Seems separable from “CRC tastes like shit”.

Distillforeal · September 28, 2020, 5:02pm

That may be true .2 micro may stop it idk. But like you said prewashing fixes it also so I am hoping I the future this will be mentioned in sops

Akoyeh · September 28, 2020, 5:05pm

Having performed ethanol CRC in a scaled manner from @TheLostBiologist’s tek, I can say that yes, there can be some cloudiness, but really, it was never something I saw. I would get media that passed through as the puck (cake) settled, BUT I could pass the same (polluted) alcohol through the same filter and achieve perfect clarity and no pass-through.

If washing the media is something you are recommending, how is it that I can use the same (admittedly polluted) solvent (usually 3 times to ensure no pass-through) and end up washing it clean? By your logic, wouldn’t these residues you speak of still be polluting the solvent?

(All of this was done woth 190 proof ethanol/no denaturants, and we’ve been talking about/actually doing this for years!)

Distillforeal · September 28, 2020, 5:07pm

If you are washing tour media obviously that solvent is designated as dirty and is not to be combined with clean solvent

Dred_pirate · September 28, 2020, 5:07pm

If you’re not using anything that’s been acid washed. This isn’t a concern, right?

I’ve stated that I filter down to the furthest depth possible.

Akoyeh · September 28, 2020, 5:09pm

BUT THAT IS THE WHOLE DAMN POINT OF USING THE MAGIC DIRT! IT CLEANS THE SOLVENT AND/OR EXTRACT!

(sorry for yelling)

Distillforeal · September 28, 2020, 5:09pm

Sorry for yelling lol

Dred_pirate · September 28, 2020, 5:10pm

Also, I might add. Washing your media only rinses the fines at the bottom of the filtration bed. And also has the capability of causing more friction with the media, enabling it to break down more and create more fines, potentially coming along with your actual run. Which you are trying to avoid in the first place. This is a conversation that I had with @Photon_noir a while back
