Food dehydrators, similar to the Mr. Coffee one, are great for food survival purposes. Dehydrated and dried foods last a long time, providing nourishment for the entire family.
One thing to keep in mind is that some dehydrated foods need clean water to consume once it is taken out of its storage container. For food survival planning, make sure to pack enough water that can be used for this purpose. Other than that, snacks made with this type of food dehydrator are ideal, such as jerky treats and dried fruit, which do not require water for creating meals, but are instead eaten as-is.
