A good example would be a person hanging out wet clothing in freezing conditions. the clothes freeze as soon as they are on the line. however the amount of water in the air is far lower then the amount of water in the clothing. and whether the water is frozen or not it will evaporate and the clothes will dry. slightly quicker if there is a breeze. All of a sudden you can see the clothes being moved about by the wind and you know they are dry. I have seen this happen. Indians in the south American mountains used to freeze dry potatoes the same way in the mountains, by leaving them out in dry freezing conditions.

What is freeze dry food?

Freeze-drying is a method for dehydrating food and other perishable products, like pharmaceuticals, medical supplies and biological samples. The material is first frozen and then placed in a low-pressure chamber so that the ice sublimates. It is the only practical way to preserve things by dehydration without applying heat (which would change the substance irreversibly). Foods dehydrated by freeze-drying can be sealed and safely stored at room temperature for years. When opened, freeze-dried foods can be reconstituted by simply adding water.

Can water evaperate in a freezer?

Yes, water can still evaporate in a freezer, but at a much slower rate compared to at room temperature due to the cold temperature. However, the overall humidity level inside the freezer tends to be high, which can prevent evaporation to some extent.
