This Digital 3-Zone fully stainless-steel dehydrator is made for ongoing commercial use. With (60) 16" x 16" trays and our high-efficiency forced air convection system, you can dehydrate your food at industrial rates. This gives you a total of over 104 sq. ft of dehydrating rack space. This unit gives you the versatility of being able to independently control each of the 3 Zones on their own. Set different temperatures and timers for each zone. Use only 1 zone or all 3. Great for dehydrating different types of food simultaneously or even doing different recipes of jerky so the flavors don't cross contaminate. Our Food Grade 304 Stainless Steel mesh trays allow food to cook evenly on both sides without the need to rotate or turn food over while dehydrating. If you need solid trays for things like flour and grains just let us know or simply apply wax or baking paper to the mesh trays. Perfect for fruits, nuts, jerky, biltong, vegetables, and more
