I wanted to share something that has been working well. I put the lowers and any quality trim in the drum and let it rotate for 45 mins or so. Everything is precooled in another cooler of dry ice. The drum is in a large cooler and there is dry ice kept inside and in a little pocket on the lid above the drum. The screen on the drum is 150 micron. There is a trey in the bottom that collects the kief and pulls out to empty quickly. I press the kief in 90 micron bags at 180 degrees with a short warm up and about 1 minute under pressure. The run pictured was 5 lbs. trim and it put out a little more than 200 grams tasty rosin.
