BR - Spinning Band / Distillate Purification

Does anyone have experience with re-distilling lower potency distillate to separate out the undesired cannabinoids to increase the total THC using a BR-Spinning Band Distillation Unit?

Im hoping to see if anyone has dialed in this process and might have some tips. I know this distillation unit can be touchy at times.

Thanks in advance

IME, re-distilling low potency distillate only increases the total THC by max 2%. The reason being the largest non-THC components of your distillate are minor cannabinoids, which are nearly impossible to distill from THC using a wiped film. I have spent probably 80 hours on that problem.

^ This is assuming you’ve already done a great job removing low boiling point and very high boiling point junk.

Thanks for your input, it is appreciated. But, for this situation I am referencing a Spinning Band unit v.s a WFE. I have ran both styles of distillation units and IME a Spinning Band has significant advantage of separating Cannabinoids due to the ability to dial in specific boiling points. My thinking is, since D9THC has a lower boiling point than most Cannabinoids, hypothetically, if the temperature of the boiling flask only reaches the boiling point of D9THC then no other cannabinoids should evaporate and condense along with the D9THC.

I’ve ran the BR a lot in the past and did exactly this. I can answer any questions just understand your oil will probably oxidize afterwards

Undesired cannabinoids aren’t the problem it’s co-distilling compounds that are not cannabinoids

Awesome, thanks for the input. Essentially I’m just curious if the idea of re-distilling would be viable and if so, what parameters are being used to achieve a higher THC potency.

We are deciding on whether we should send our BR to New York. Currently, most of the distillate we are purchasing there is coming from outdoor grows so there are excessive minor cannabinoids in the oil.

To answer this a current coa of the oil you want to resistible would be needed
What’s the thc % now
And cbd %
Wich minors are you seeing ?
I have had more succes with rewinterruzung in general
Defenatly with outdoor wxtracts

It is helpful to have accurate breakdowns of what is in your distillate already, so you know what to remediate. What’s the total cannabinoid content? What percent of that is minor cannabinoids? What else is in there? Once you know what you want to remediate, you need to find each compound’s enthalpy of vaporization and plug it into a pressure-temperature nomagraph tool. This tool uses the Clausius-Clapeyron Equation to calculate the boiling point of each compound at the vacuum depth you’re able to get down to while distilling.

Once you find all the boiling points of all the impurities you want to remediate at the vacuum temperatures you’re reaching in distillation, you can use these data as a guide to set your evaporation and condensing column temperatures.

The temperatures you want are not going to be the same as the temperatures other processors want. It’s all about that sweet sweet R&D baby.

Bingo - works better to re-winterize and re-distill.
Both is ideal. Maybe try that first!
