I started another run last night. Only a partial run, 1 tray out of the 4 is all that’s in use (although it was pretty full). I’m controlling the method in which this tray is dried in order to provide a control for some experiments. Although it’s not done yet, I can say with confidence that one of the ideas I had for a freeze dryer is current a definite win and something that will improve the process significantly. If I get to, I’m going to name my method of freeze drying the “Ledford Method” :-D
