In my experience, any pressing of material I did caused it to pull more fats/waxes than it typically does. This is purely anecdotal and I don’t have any literature to backup this claim.
If you winterize, it does not make a difference. It just doesn’t work for me since I don’t winterize my cryo etoh extractions.
Well the new cup v2.0 spins at 1800 rpm. I just went over and talked to them about it. This shortens the spin speed also due to that this new one doesn’t have a ramp up time. Goes 0 to 1800 instantly. So you can do 4 runs an hour instead.
Im curious as to why there aren’t compliant centrifuges in bulk. There is certainly a demand for it. The one you linked previously is $30k, which seems steep for something so simple.
Do you have any knowledge on approval for certified labs? Im tempted to design a centrifuge and get it approved. Could be something this industry is lacking.
electronics will need to be potted. Motor will need to be sealed and probably DC brushless to get your speed control (although PWM will work).you will need an engineer willing to sign off on it. not sure PSI (folks used by Precision and a couple of others) will work.
Once upon a time I figured I could hack one together for about $10k assuming I did all the fab work. I’d have to get better at tig, and I would have sourced used parts. Would have cost me another $10k for engineer sign-off I reckon.
I guess it didn’t happen then. I was waiting for them to send me that quote, but I’ve only got it over the phone and i can’t find any links on their page.
It’s basically a bunch of stacked membrane filters, using pressure instead of vac by pumping the liquid through. Automation can be nice, but can you automate cleaning? Much better than huge buchners, but still a lot of cleaning and maintenance. My experience was with a different sticky product, so maybe spent plant matter and kief is not so bad to just spray off though.
For EtOH soak I just squeeze it out in a mesh bag, call it good enough. Spinning it off sounds really nice, but if you need something air powered, filter press could be the way.
Btw, what size filter did they give you? 30 inch, triple stack lenticular? I’m trying to figure out if a inline 10 inch single stack would be usable instead of a 10 inch ss buchner.
