The reason i keep my oven at 85F throughout the day or till i fill it cause i dont want to cook the oil thats in the oven from previous runs in that day. Sometimes my single runs dont fill the oven. So i run until my ovens are filled or im done. I dont want to have a run of one strain…pull vac…then have to release it to put more oil in that oven. So i just keep my oven on with runs from the day. When im done running or the vac is full…then i wait till all the oil has gotten to the same temp(90F) as the oil i run at 9am might not be the same internal temp is the run i just finished at say 3-4pm.
I use all AI ovens .9 and 1.9cu ft ovens with the matching pumps as they sell on their site. I figured they spent more time on matching the pump to oven then i could ever. I only do the calibrations on the first time use. I do the calibrations according to the manual…i think this video explains it but i use the manual:
I open the oven fast and try to get laser temps all all trays and in different points. Ive done this several times over the first day with my ovens. I will adjust my oven accordingly.
I keep the oil in the oven without vac to get the extract to a higher temp than i recovered. This makes the surface retention of the extract a bit easier to pull the solvant out, and i know 100% the temps are stable by experience with the laser thermometer over time.
Im sure my tech aint the best by no means but its what works and pretty darn well. Id like to here others and maybe i can improve my tech. Hope that answers your questions. Thanks for having me clairfy those details. I guess im not good with the SOP things.
