NASA does not make freeze dried food, they buy it from contractors that make it to NASA specifications (like everything else NASA uses).
Freeze dried foods are made by freezing the food, then placing it in a vacuum chamber. The vacuum causes the frozen water in the food to sublime (change directly from solid to vapor without melting). After all the water is removed the food is removed from the vacuum chamber.
