Freeze dryers are machines that remove water from food by sublimation, which is the process of changing water directly from a solid to a gas. This process preserves the food’s nutrients, flavor, and color, and it can extend the shelf life of food for up to 25 years.
Freeze dryers are used to preserve a variety of foods, including fruits, vegetables, meat, and seafood. Freeze-dried foods are lightweight and easy to store, making them ideal for camping, hiking, and other outdoor activities. They are also a good option for people who want to eat healthy, nutritious food without having to worry about spoilage.
