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.
Probably not. They aren’t mass produced to the same extent because while there is a market for them, that market isn’t even close to as large as the microwave market.
Also, I highly recommend Technology Connections’ video on freeze dryers, as it highlights why it’s not as useful as they may seem - They have their uses, but freeze drying is not the ultimate food preservation method.
The video goes in depth into how freeze drying works (and doesn’t), and I recommend watching the entire thing and evaluate whether you actually need one.
