Guys, thanks for the responses.
@Hansel you are right, I bought the trim from a distributor via metrc. The lab results from the seller showed high THC and almost non existent CBD, so CBD is not an option in this case. I also had the oil tested after extraction at our local test lab which confirmed that there is almost no CBD in the oil.
As for the SPD, @mellodee, let me give you an idea of how I run it.
I start with a small amount of filtered, decarbed crude, at around 200g as I’m still at my R&D stage. I preheat the oil to 80c and then poor it into the boiling flask (which is also preheat). I set the first setpoint to 120C and from their increase the temps slowly and gradually till I hit 200c. Below is the graph of the whole process:
x-axis: time in minutes
y-axis: value (temps, pressure in mTorr)
Red: temp in boiling flask
Lime Green: head temp (vapes)
Blue and Pink: the pressure sensors
So @mellodee, do you notice any spots in SPD procedure that would require some tweaking? Also, what do you mean by “You just need the right layering” ?
And here is another one from couple days ago. This is after the 1st pass distillation. After 2 days I can see some crystal like stuff forming on the surface of the oil and nothing under as you guys can see in the photos below:
Any help is greatly appreciated guys. I’m in the dark with this right, trying to sort this out before I get into my production.
One of you guys said the right words, “…if you ask 10 people about one thing you will have 10 totally different versions to solve that problem.”. So my SOP was structured on 10:1 dilution with 200 proof food grade ethanol, then 24 hours at -40c. And then I was told by a reputable manufacturer that you need more than 10:1 for the ethanol to be able to dilute the crude and separate the bad stuff (waxes, lipids, fats etc). Then another manufacturer recommended to go all the way down to 5:1 and that is the sweet spot for the dilution, and said that with higher ratio the ethanol will bind up with the waxes and lipids and pass through the pores of the filter paper, hence the bad stuff will end up in my oil and not on the paper.
So at this point I’m going back to my initial plan of 10:1 ratio and see how it goes. And again guys, if you have any thoughts or suggestions please share and help me to resolve this problem.
