Pumping a slurry into a centrifuge running at low speed

@Rowan isn’t playing with a panda, and is trying to load a slurry into a moving basket.

There are a couple of issues doing this with a panda.

One is they spin so damn fast, so they really do try their best to become rocket ships if you pour too fast.

Another is that the rotating mass is almost ALL the mass, making lift off far more achievable (but everyone knows to strap down a panda before feeding it liquor and cannabis at this point right?).

Im specifically looking at the cedarstone 150 model

And honestly all this talk of straps and dancing makes me lean way more heavily towards a Vincent press.

Doing slurry loading in a standard basket fuge is a terrible kludge.

Look for a scraper or peeler centrifuge instead - they’re designed to be loaded with slurries.

Aren’t decanter centrifuges made for slurries or a bottom discharge scraper centrifuge

Yep.

That’s not what OP has on hand.

Rumor has it he’s feeling screwed and (de)pressed.

Peelers/scrapers come in side or bottom discharge. Are both perforated basket fuges.

Neither should be confused with the decanter

Im gonna stick with what i know and squeeze reak hard

Hugs!

A fuge basket got loose and hits you you’re most likely dead. It being full of solvent and going off track and spinning at you at high rpm that’s also a flamethrower spinning at you.

A closed loop hydrocarbon extraction unit like Butane/Propane/Isobutane… It’s a live grenade that you can and have to diffuse but make no mistake the solvent leaks and finds its way to an ignition source and its game fucking over.

A c02 extraction unit can do serious damage with the explosions that could occur of something went wrong… A c02 extraction unit is an automatic high pressure bomb that could nearly obliterate the operating environment and most likely kill or paralyze someone unlucky enough to be around it.

There’s a lot more that can happen like burning the shyt out of yourself on a rosin press that accidentally starts to have cascading heat issues and you end up on fire or burning your flesh so bad it looks like a plastic toy being melted… think of robot chicken.

… A vaccum pump could catch fire and explode. A beaker could burst with solvent in it. A heating mantle or water bath could go faulty mid run. Water chillers could go faulty mid run. An electrical fire. Your lights going out and the back up generators cause a spark and an explosion happens.

… Always be mindful of the possibilities and the fire exits.:point_up:t2:

This is why i am going with a vapor tight @VincentCorp1931 screw press.

Whats gonna happen with a screw press? They’re brutally effective and simple tools.

Depends the type of centrifuge used. There are continuous style vertical basket centrifuges out there. The few that I have seen have a raised spindle bowl to allow for liquid/solids present while spinning.

I wouldn’t recommend it on a typical centrifuge we see in our industries, good way for the centrifuge to walk away lol.

Yes, you can indeed drive screws into any substance you like with a big enough hammer.

A screw press in my experience is a filtration/OPx nightmare. Literarily the last type of liquid/solid separation I would recommend.

would you care to share your experience?

The amount of undesirables and suspended solids that make it through on the fluid stream is a lot.

A centrifuge is a much cleaner liquid/solid separation IMO. Granted there is generally a secondary solvent removable on the decanter and batch inputs on a standard top-load centrifuge.

After building a massive continuous automated chilled decanter setup, I just believe the simplistic way of a top load centrifuge is the way to go. Dry Material in, solvent in, soak, drain, spin, Dry Material out. Again just my opinion, feel free to DM me and we can chat on the phone if you want to!

I run a pretty extensive post purification routine that takes care of all of that.

Cryo ethanol is IMO the worst thing you can possibly do for OPx, but its simple to understand and easy to sell so there is mass appeal.

I make a lot of topicals, cannabis wax is actually valuable to me, I’m a whole hog type of butcher and have been my whole life

from a “whole hog” perspective, if you’ve got the cedarstone and don’t have the Vincent, I reckon you should run what you brung. I’d skip the slurry loading unless you can also get the fuge to empty itself. if you’ve got to pull a bag out, and empty it, you might as well put biomass in it before throwing in back in…

I’m mean Vincents are cool and shit…

Pretty sure that one of the sales reps for Vincent is associated with Plant Works Group and they don’t even use the screw press for primary dewatering/solvent removal of their slurry. I believe they go decanter then screw press. I’ve always took the that to mean their aware of/ implicitly agree with what @EngineerZach is saying.

In my personal interactions with them, they recommended I have a settling tank after the press for the large amount of sludge/suspended solids it produces. Even with that, we used 8-10 more bag filters relative to our top loading centrifuge in a day

put a 1um liner in your fuge ==> the only filtration needed is for shit that missed the bag.

The .5 micron clay particles will still be an issue.

The harder it is to get ethanol into the bag, it is even harder to get the ethanol and oil out as a solution. Anything below 100 micron on material bags has shown a noticeable yield loss with all other variables linear.
