NESCO FD-80 Snackmaster Square Dehydrator & Jerky Maker Type: Food Dehydrators Features: Adjustable Thermostat. The adjustable thermostat allows you to dry different foods at proper temperatures (95-160 degree F), providing the flexibility to produce the best drying results. New-Powerful Top Mounted Fan. Top mounted fan and 700 watts of drying power generate maximum speed and quality for dehydrating fruits, vegetables, and jerky. Helps dry food in hours, not days like other food dehydrators.
