Food dehydrators come in many varieties.  There are two main types – those that have stackable trays and those that are constructed of a stiff box with removable shelves.  Some are quite small, fitting nicely onto the kitchen counter; while other electric food dehydrator choices are large and freestanding.  Some have fans to move the air vertically, while others move the air horizontally.  Another type uses convection drying with no fan needed at all. It’s important to decide what type of food dehydrator you need based on your plan and purpose, and to buy according to your intended use.  Whether you select a five tray food dehydrator or another one, you’ll have delicious dried fruits and vegetables all year long.
