With the CUP, the extraction takes place in the centrifuge. There is an agitation cycle, or you can spray solvent while spinning.
The spray mod on the NSEP is trivial (per their engineer: spigot in the lid), but the agitate mod may be a little trickier. or not. depending on the drive system. speed control should be built in. reverse may or may not be easily retrofitted. Closing the drain is also easy to add if it’s not already part of the package.
NSEP has a rotor lifting crane & removable baskets that they can sell you.
I too am needing to purchase a compliant system for this new, wild world of quasi legality. I’m probably going to go with the cup2.0 since it basically offers a turn key solution but i would much rather have a few 10bbl jacketed conical fermenters and one of the large western states centrifuges that top loads and bottom dumps… It’s a few hundred thousand more but a whole lot more throughput capability…
Any feedback or advise from current owner/operators would be greatly appreciated
Friendly reminder to please keep all For Sale / Wanted posts in Classifieds - Future4200 - cross linking to here would be appropriate. This will keep the thread relevant for people who show up X months from now.
That’s so shitty. Why would they not jacket the damned thing?!
I would probably buy one or two if I could keep it cold during the process… Anyone willing to weld a jacket on one? @PinnacleStainless??
Also, in efforts to not spend 75k on a 6lb extractor…
I am considering just hitting spent biomass with steam in order to remove the last of the ethanol. This means I’ll need to use a little extra solvent during extraction to wash the biomass clean of cannabinoids, as well as have a distillation skid for ethanol recovery from water. I’ve found a decent amount of cannabinoids to come out of the centrifuged material when extracting at a solvent ratio of 1 gal ethanol : 1 lb biomass
the solvent leaves the centrifuge several times to achieve that temp rise. insulating or chilling the vessel the solvent goes into during biomass exchanges would alleviate much of it. but you’re right, a second jacket would also help.
We’ve now got that vessel in a -40freezer, but I’m not yet happy with the plumbing. I intend adding a heat exchanger into the circuit to make dialling my temps in easier.
@dr_good_life, the instruction manual explicitly states, multiple times, that vacuum is never to be used on the system chamber. it is not rated for vacuum or pressure and improper use, according to the manufacturer, will void any warranties. I’m not curious enough to risk voiding the warranty and breaking a machine I can’t afford to replace. Thankfully, Nitrogen is pretty inexpensive.
looks like it has somewhere for the guys with the shovels to stand while they’re emptying it
can you comment on where it’s coming from and what it’s gonna set you back?
rotor diameter and max rpms so we can figure out the g-forces would be awesome too.
edit: looks like http://peonyfns.com/cenpptd.asp although they don’t list a 300L model. assuming the PPTD-300, it’s 430g’s, which is between the CUP 1.2 & 2.0.
dunno. the image posted by @highestzen is labelled “PPTD-300 centrifuge.jpg”
which is how I found the manufacturer’s website.
I doubt highestzen would have bothered having custom bags made if they’d purchased the “bag lift” model.
bag lift model also seems to be lacking the platform for the guy with a shovel to stand on while emptying the basket. see Vacuum systems for getting rid of spent biomass for background on “guy with a shovel”
