Does anyone freeze dry? What machine/process do you use?
I have a Nesco dehydrator. I love it-
Try this link: http://preparedforthat.com/how-to-freeze-dry-food-at-home/ It can be done at home, generally requires a vacuum chamber or dry ice, but can be done in the freezer alone. I have never tried any of the methods and don't know anyone personally who does.
