massive pentane crash?

Is that 2 separate vessels? The impeller looks different

Them some gorgeous jewels….

Looks the same to me. First pic looks to be with enough solvent to dissolve thca and the second picture if after solvent is removed to be closer to finished thca growth.

What about that circular part on the impeller?

It’s just raised up and taken from a different angle

Yup large solvent reCx. Same impeller actually 3 impellers, two the same kind and a third to keep whatever is in the vessel mobile when the tank bottom valve is opened. The ring stabilises the impeller.

Very nice 
Wonder if the baffels are productive or counter productive actually doing some r and d on the matter at the moment
Any hint on the rpm your running ?
Vessel I am trying this on
Hope the rpm is sufficient to keep it all afloat and not stuck on the walls
Without an impeller as with a small impeller it was not much of a succes

Only use the impeller to dissolve the crystals round 300rpm. The baffles help a lot to prevent a vortex while mixing. Then the solution just sits and cx’s grow.
Hmm ok difrent tech I am implementing
I keep the mixer on all the way to make
Sand consistency to transfer to a pusher centrifuge it s also my first crystelization
So no need to get to diamond size
But yes think the jars and Pyrex pan times are almost history

I’m looking forward to the first continuous crystallization systems.

they are so common in other industries, my books show all sorts of examples on continuous crystallization.

I have been thinking about stirred batch crystallization reactors and from what I’ve seen the impellers run extremely slow. Then lower solubility by dropping the temp to precipitate or increase supersaturation by removing solvent, when it hits the right point sugar will start.
To make thcA sugar I think it can be done in a stirred reactor, but for big faceted stones, by big I mean like stones 3/16" or larger. I’d love to see the parameters, time, temp/temp curve, RPM*** (maybe 1 revolution per hour), impeller design and the starting purity in the mother liquor.
We’ve done potency on sugar vs stones (as an analogy think small table salt vs bigger rock salt) the sugar always tests lower.
Yes sugar often tests lower but minimal not a isseu for me
What I want to try is a 2 layer solvent
Alkane glycerine since water hurts the speed
Of crystelization As for rpm depends a lot on vessel and impeller on the vessel I have shown 60 rpm is minimum to avoid growth on the walls and botom
As for diamonds movement is finicky
So the idea is glycerine botom layer alkane top
Slow mix and pass treu a sieve daily sieve pass treu redisolve and those trapped back into mother liqueur let them grow till mass is large enough to sink in the glycerine
(Wich can be rinsed of with water if needed
As for evaporation and temperaturen drop
I use them both
Hexane still has some vapor pressure at -40C
So A very light vacuum is pulled with a even smaller pump (air breathing ) before the coldtrap so not to freeze the coldtrap with humidity from the breathing vapors (needle valve) at about 1 liter solvent per hour
300L mother liqueur
Anti solvents are a pain to work with so far
