How to Freeze Dry at Home - Harvest Right Freeze Dryer Overview
Freeze-dried food for years was once reserved for soldiers and astronauts. Today freeze dried food is so popular for disaster-prepared survivalists, dietary needs for a healthy lifestyle and outdoor enthusiasts such as hikers or backpackers. People love to snack on it while it’s still in its freeze-dried state or you may just add water to quickly rehydrate food.

HISTORY OF FREEZE DRYING
The first application of the freeze-drying process was in the Andes, Peru, where indigenous people took low-land tubers up to high elevations and left them to freeze. Potatoes were squashed to evacuate water and, when left to freeze at night and exposed during the day, the mash would lose its remaining water while nutrients were preserved through the lyophilization process. This resulted in a food called chuño, with a long shelf life eaten well past its seasonal availability, that could be stored as emergency rations.
A significant turning point for freeze drying occurred during World War II. Blood plasma and penicillin were needed to treat the wounded in the field, and because of the lack of refrigerated transport, many serum supplies spoiled before reaching their recipients. The freeze-drying process was developed as a commercial technique that enabled blood plasma and penicillin to be rendered chemically stable and viable without refrigeration. In the 1950s–1960s, freeze drying began to be viewed as a multi-purpose tool for both pharmaceuticals and food processing.
