Do you have the same issues with hexane?

Weld it, for less than 8k.

I donāt use hexane but I imagine it could come up the same way (usually when the light phase has a bunch of shit dissolved in it and the heavy does not).
I will certainly be putting up pics when I get it disassembled

What have been the results to your testing? What have you tested?
THC, CBD, Water (brine, low ph, high ph, netural), Ethanol, Methanol, Heptane, Hexane ā¦

Iāll be totally honest, this thing has been sitting on a shelf in the lab for ever now and I just havenāt had time to get it fired up and running. Iām literally ashamed lol. I will say that we tried gravity feeding it and yeah, that dog donāt hunt. Got some peristaltic pumps for it but havenāt fired it up since they came in
Cool tech, never understood it until I looked up that company CINC.
I had a small one for awhile. It worked with pentane, but was finicky. I prefer a disc stack because you donāt have to vary the speed for good separation.
How well is it on LLE
Of say salt water / alkane/canabinoids ?

Iām curious as well. Iāve done a lot of LLEs in my time and Iād love to make it a continuous process

It was ok. Not impressive. Once i found the right weir, flow rate and motor speed, it could run continuously. Itās more of a scalpel than a hammer. After using a disc disk and agitated reactor, Iāll never go back to a counter-current centrifuge.

Whatās your favorite disk fuge ?
Alfa laval ?

Iāve had limited experience with Alfa Lavel but it was a very solid piece of equipment. It was able to handle some pretty solid organic/aq. LLE separations significantly faster than the tried and true mix in a large reactor and let separate naturally over time.

The good thing of countercurrent at least how I vision it is that all washes can be done in one flow 4 units chained
With different water currents entering
I ll need to contemplate this with a disk fuge
If you donāt need heavy agitation in your LLE - and most operations in this industry donāt seem to - itās not all that difficult to set up a reasonably continuous semi-batch process with a tall column, some sight glasses, and some gear pumps/valves.
Hmm trying to get a picture of what you mean
But this I asume is yust a way to get faster separation of a singel batch
My favorite is one that is cheap, clean and works. Weāve gotten all the ones we tested to work. Havenāt needed to use a solid discharge unit yet, but they seem dope.
You can do multiple stages with disc stacks too. Iāve run them in batch or continuous processes. However, when you can run 35kg an hour, you donāt need multiple stages in most cases. 2 passes is still over 15kg an hour.
