Well, is the problem with home freeze drying maybe the temp which you must freeze to get the evaporative effect? I don’t think the vacume would be expensive to setup.

For example does the temp need to be -60 or lower? This would be difficult with any home freezing equipment. Could dry ice be used in an experiment to achieve lower temps?

I can see the possibility that it might not be feasable in small quantities such as 5 quarts of stawberries vs 1000 quarts. So that only freeze drying in larger quantities would be worth it.

Maybe 4 families could go in on a comercial freeze dryer and share it.
