Losing cannabinoid in 1st fraction

I’m working with a wiped film system processing EtOH Hemp crude. We had potency tests done on our 1st pass (Degas/terp removal) and are finding the first fraction containing about 30% CBD. Our temps shouldn’t be high enough to be stepping into the main body. We are throttling back our vacuum depth during this run also to about 0.1 torr. Has anyone had a similar situation? Is this a normal occurrence that I just have not ran across yet?


Don’t bring the vacuum level down, just the tempatures. You can absolutly strip the cbd off if your perameters arent right.
