When Microwaves first came out they were huge but with a tiny cooking area and they were not affordable, and were mostly in business kitchens and a few restaurants. I would love a freeze dryer but the cheapest I have seen is $1600 and they only have 4 small trays.
No. For every one freeze dryer that is sold 1000 microwaves are sold. The consumer demand simply isn’t there outside of niche communities like survivalists
