FEATURES Four Preset Thermostat For more control over the drying process, this food dehydrator comes with an adjustable thermostat. There are five positions on the dial to choose from, including “Off.” These settings are “Fan Only,” “Low,” “Medium,” and “High.” Each of these corresponds to a particular temperature, with “Fan Only” being a good way to draw out extra moisture. The low setting is 110F, the medium around 140F, and high about 175F, according to the manual. Stackable Trays As a vertical flow model, this food dryer comes with plates that sit one on top of the other. They are made from clear, food-safe plastic which makes it easier to keep track of drying. For more versatility, there’s a solid sheet that comes with this unit. It is ideal for making fruit rolls and leather out of purees, jams, etc. If you want to expand, the Waring Pro can accommodate up to nine trays. Improved Airflow Airflow is one of the most important aspects of every dehydrator unit. To help moisture evaporate during the drying process, this model has a lid with a mesh center that lets humidity escape. Moreover, there’s a fan located in the base, which pushes out hot air and spreads it out evenly. Easy To Clean After you’ve dehydrated vegetables, herbs or fruits, you can pop your trays into the dishwasher for cleaning. With machine washing, you don’t have to spend precious time scrubbing each mesh. If you have stubborn stains, soaking in hot water beforehand does the trick.
