There's all kinds of info in here about freeze dryers that I never knew I didn't know.

I still don't want a freeze dryer, but I can now speak authoritatively as to why.

Not sure I can commit to an hour of this but I’m curious why shouldn’t someone, per the video?

They're REALLY expensive $3k for his unit which isn't even the top end.
They're loud
They run for an entire day for one batch
They consume a massive amount of electricity (1 day freeze dryer vs 30 days of a regular freezer)
The prep time for the food its VERY extensive.
If you don't prep just right the food is wasted
the amount of actual food produced is really small
Even if you're fine with everything else, shockingly few things actually taste good after freeze drying.

Additionally:

while the food will taste the same, in most cases the mouth feel is so horrendously bad it will be inedible
rehydration of most foods is very hard to impossible, limiting it's uses even more
if you put more than one kind of food in a batch, the chance of error in the process increase dramatically, because all food needs different amounts of time to dry

I'm pretty sure the only actual use cases are berries and fruits. But those can all just be dehydrated normally or made into jam, so there is little to no purpose for a freeze dryer, except playing around with foods, which is not worth the price

Also great for making great hash out of weed

Primarily because it’s a $3k piece of equipment. There are myriad other food preservation methods (canning, pickling, drying etc) that compete very strongly on the price/performance scale.

For some people it’s worth it, but for most use cases it’s going to be cheaper and simpler to go with an alternative method. There’s nothing wrong with the equipment or the technique, it’s just the value proposition for the consumer is low and the entry cost is high.
