I was only running one tray this time. I specifically didn’t add any heat, although I stirred the mixture roughly every two hours. Total time to freeze dry was about 44 hours, including secondary drying. I’m hoping to get the total elapsed time down to 24 hours including secondary drying. Material appeared to be about 2/3 water based upon volume loss in freeze drying. I could probably condense the mixture further before drying and be just fine.
