Okay so I want to build a one gallon an hour small scale falling film evaporator for cheap. How can I do it. I require le spoon feed.
Sounds like a rotovap would be an easier route no?
I have one but I want to make a small one to compare plus I want something where I can pour out the oil easier.
I just watched this today Entrevista a Quinton Van Gundy Colorado Extractions MJBIZConference Las Vegas - YouTube
After seeing a spray vap advertised on here and it got me interested in making a stainless one for one gallon an hour. Or a small standard falling film design that can do 1 gal an hour plus it’d be adorable
It’s quarentine I’m bored and I’m gonna have money to waste after I sell a vacuum oven in a few months
Buy a couple of shotgun condensers, some caps, and some 180* fittings. How did you want to heat it, did you need vaccum as well?
I was gonna rig up some kind of tankless hot water system on a digital temperature controller and pump it thru with a sump pump and I was gonna use super saline with dry ice for the cold side pumped by mag drive pump or maybe some kind of heavy duty lift pump I was gonna go back to the pool pump thread I made and take ideas off of that
vacuum?
Does it have to be heavy or can a standard diaphragm pump run it? I’m always unsure cause I keep seeing gear pumps and shit.
The co2 bubbles from the dry ice will cavotate the pump
gear pumps for the feeds going out of the evaporator, piston vacuum pumps like the kind used for a rotovap should work.
Works well for my RotoVap and the fish tank pump I use now
Help me out then, cause I’ve got 2 shotgun condensers I can’t get to run
What is the application/ how are they connected? What is the internal tube count?
3 lbs of Mortons salt per 5 lbs of ice is how I do it. I wait till it’s halfway done bubbling before I run my fishtank pump.
Yeah I was just gunna check thst thread out cause I saw it pop up and hadn’t heard of a sprayvap- definitely seems interesting
Seems like it would be easier and cheaper to make one out of stainless.
There was some reason why sprayvaps were suboptimal for cannabis oil but I can’t remember why that was right now.
Interesting to hear, if you can remember why I’d love to hear. It sounds like a useful option for purifying etoh though, that being said I know there’s other options out there, that are probably cheaper/more efficient than a spray vap
