The user-friendly controls make it incredibly easy to set the timer from 1-24 hours and adjust the temperature between 90 - 155°F. You won't have to search through a manual for instructions, as there is an informative guide right by the controls for dehydrating fruits, vegetables, meat, or jerky. If you plan on sticking to the same menu, then our preset temperature buttons make cooking simpler and faster. With just one click of a button, your meal can be cooked at up to three different customized temperatures according to whatever recipe you are following. Our all-digital user interface is both easy-to-use and straightforward for setting it up!
