I was curious. I have this super slow Short path. Sometimes the runs can be up to 12 hours to run through a couple kilos of crude. (It’s a CES 5 liter in case you were curious) But what I was wondering if there was any harm in turning the system off half way through the run and then turning it back on the next day. I have been hesitant to do this, but there are days where I can’t afford to be sitting in my office for 12 hours waiting for a run to finish.
I’m a scary cat also leaving equipment running and not being their lol. It gives me anxiety if I can’t have eyes on what’s happening at all times. They have cameras with 360 view that you can zoom into your parameters. Place one of these in front of your machine you can check it from you phone.
I would strongly discourage shutting down system mid run. Best case scenario is you only isomerize or degrade most of your desired cannabinoids because of such a long residency time in flask. I’ve spent quite a lot of time on the CES short path machines. What temps are you running at what fractions? Whats your vapor temp at? With the CES 2L or 5L Ive seen In boiling flask I usually hit 85c for solvent removal, 165c for volatiles, 188c for heavy volatiles and 200-210 mains. A long run generally takes me 8 hours though…wondering where your extra time is coming from.
I never ran an SPD but my knowledge just about any process is best for continual usage of the set parameters other than start up/shutdown. I agree with what your saying.
All of my temps are spot on with what you said, but I think I might just be spending too much time on each one. I tend to just bump up 5-10 degrees half hour or so till I get my boiling flask to 220 then just let it chill
My vapor temps are at 190 pulling mains and I feel like I’m rushing things… running a single kg through my 2L doesn’t take more than like four hours tops what are these 12 and 8 hour runs about?
My 5L was a six hour open and shut case with vapor temps down in the 170s
A typical run for me on my 2liter cheap spd takes 6-8 hours or so. Usually end up with good product tho… atleast for a newb
With that being said, as for your question. I do know that the material in the boiling flask stays VERY hot for a long time. So I would thing that having it sit So hot after shutdown for no reason would just roast it.
Yeah once the temps drop it’s really good practice to dump some ethanol into the flask (I mean COOLs down a LOT or you’ll rupture the glass due to thermal shock) then run hot ethanol at atmosphere through the whole still to clean the glass out and make sure you don’t have to pull a @Demontrich and throw the whole flask away.
