This innovative design features 700 watts of drying power, and generates maximum speed and quality for dehydrating fruits, vegetables, beef jerky, and venison jerky. The top mounted fan eliminates liquids dripping into the heating chamber! FEATURES: The adjustable thermostat allows you to dry different foods at proper temperatures (95-155 degrees F), providing the flexibility to produce the best drying results. 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. Expandable FD-80 comes with 4 trays, but is expandable to 8 trays. Additional SQT-2 Add-A-Trays available in sets of 2. Patented Converga-Flow drying system forces air down the exterior pressurized chamber (not through the trays). The hot air is forced horizontally across each individual tray, converging on the core for fast, even and nutritious drying. No flavor mixing and no need to rotate trays.
