A dehydrator dries food by using heat only, while a freeze dryer uses both cold and heat. Dehydrated food still has moisture in it and works for short term storage only.
•The shelf heaters can be set to automatically control the rate of sublimation during the primary drying cycle. Through this process, the unit has control of the attendant vacuum pressure.
The longevity of freeze dried food depends on the what the food is and how it is stored. When stored in a mylar bag with an oxygen absorber, many foods can last up to 25 years. If stored in a glass mason jar with an oxygen absorber and a vacuum sealed lid, food can last about 5 years.
