How to freeze dry ice cream
A typical batch of ice cream runs about 36 hours in a home freeze dryer, plus about 5 hours of extra dry time. Plan on about 4 months of good quality for freeze-dried ice cream, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. These are typical estimates from the FreezeLog guide, not exact times or a safety limit. Read the safety note below before you start.
General guidance only. Follow your freeze dryer manufacturer's instructions and current food-safety guidance. These are rough figures, not a promise that any food is safe to store or eat. Actual results depend on your machine, load, packing and storage.

Safety note
Dairy products are perishable and freeze-drying does not change that. Use only pasteurized, fresh, properly chilled ingredients, keep dried product sealed and dry, and discard anything that smells off or looks unusual. Extension services list high-fat, high-sugar foods like ice cream as harder to dry and quicker to turn rancid.
How do you prep ice cream for freeze drying?
Use store-bought ice cream, or a homemade base that is cooked or made with pasteurized eggs and dairy. Do not use homemade ice cream made with raw eggs. Slice into thin pieces and freeze solid again before loading.
How do you load ice cream on the trays?
One layer, pieces apart.
How long does it take to freeze dry ice cream?

How do you store freeze-dried ice cream?
Pack as soon as the batch ends, because sugary items soak up humidity fast. Use a sealed container or mylar bag with an oxygen absorber.
What is the shelf life of freeze-dried ice cream?
Plan on about 4 months of good quality for freeze-dried ice cream, as long as the food is fully dry, sealed in an airtight container or mylar bag with an oxygen absorber and stored cool and dark. That is an estimate of quality, not a safety limit.
How do you eat or rehydrate freeze-dried ice cream?
Eaten dry as a crunchy snack. It does not rehydrate into ice cream.
