If I keep my purge temps between 90 and 105, with a full vac (my guage pins out at 30), after the winterization process, would i risk decarbing at any point unless I ran too long after the polar solvent bubbles stopped and the solvent was purged(i winterize with etoh 190)? I was worried about vaccing my winterized stuff, because I dont wanna damage terps and as much as id love to just air dry for weeks or more, Im curious what the minimum I can get away with in a polar solvent vac purge in order to keep my product tasting its best, and still become an absolute shatter. My first attempts were with one batch that may have been decarbed a bit in a primary butane vac purge by reaching temps above 130 , but i have since moved to hotplates instead of griddles and acheived a perfect 105F and can even go a bit lower with my chamber in a water bath, and have winterized some higher quality matierial and still only got it to a sap after 3 days of air drying on blades in a dehumidified room , under a fan as well.Before i begin to winterize my high grade runs that i have sitting, I really want to get my method of drying down . I know qwizoking talks about no heat, and fans but whats the next best way without waiting weeks? If I thin-film vac purged the winterized oil, after air drying to a sap consistensy, at 95F , how long do you think before id risk pulling terps or decarbing?What about a bleed-off valve to lower my Hg to something below full vac but just enough to pull solvent bubbles at 95F? Just trying to get there and still be as delicate as i can on the product! Was thinking of using a misting bottle to mist the winterized oil onto oil slick pads or parchment then doing a vac purge at just above 90F might be the most delicate i can get but not very efficient . What about using dessicant boxes with airflow where the thin-film is near a dessicant at room temperature ? All things i am unsure of since I have yet to make a true absolute....
Also when you say it can decarb as a natural function of drying... what steps can be taken to avoid this problem, and are you referring to the drying of the flowers? Or the drying of the extracted oil? Or both? We keep most of what we run in a room with a more or less constant dehumidification , not 24/7 but close , due to living in a high humidity area. Could we be possibly decarbing the material by over drying?
