Harvest Right Freeze Dryer (5 Year Review)
First, freeze-dryers use extremely cold temperatures (-40° F) and a vacuum to remove 99% of the moisture from a given food. This works because it allows the ice to change directly from a solid into a vapor without passing through the liquid phase. In turn, the food them becomes shelf-stable for about 20-25 years with proper storage.
