The Excalibur 3926TB Electric Food Dehydrator has a 26-hour time so it is ideal for dehydrating a wide range of foods such as fruits, vegetables, jerky, homemade yogurt and so much more. It is the perfect way to make wholesome snacks for you family. Excalibur's patented Parallexx Horizontal Airflow distributes air evenly over each tray allowing food to dry faster, retain more nutrients and taste better. Hyperwave Technology ensures food temperature stays low enough to maintain enzymes and nutrients in foods being dehydrated by controlling evaporative moisture. With 9 trays that measure 15 x 15 inches each, and 15 square feet of dehydrating space, you will have plenty of room to dry a large quantity of food. The adjustable thermostat lets you set the temperature from 105 degrees Fahrenheit to 165 degrees Fahrenheit.
