Basically, what i do as well. I. Do use a oil still to recoup most of the wash. This picture is what i have left after I've collected most of what i startedwith.Yep basically is a qwiso with a little more filtering thanks for sharing
I'd take the washed material and dump that into the collection container and mark the full level with a piece of tape. Then while running the still I'd stop about 1/4" below the tape mark. (Saves opening and closing the still)
Another trick" get a cabela's jerky gun with a screen for a sink in the end and squeeze the material near bone dry.
