How do they turn freeze dried food into powder?

I’m curious to know how they freeze dry whole foods and then turn it into powder.

Chosen Answer:

The food, be it meat or veggie is dehydrated then ground into a powder. Much like shredded jerky that comes in a can or bonito flakes used in furikake (rice seasoning).
