It's sleek, contemporary design features 500W of drying power and generates maximum speed and quality for dehydrating fruits, vegetables, beef jerky, and venison jerky. Helps dry food in hours, not days like ordinary food dehydrators. The top mounted fan eliminates the worry of liquids dripping into the heating chamber. The adjustable thermostat allows you to dry different foods at proper temperature (95 deg. - 155 deg.F), providing the flexibility to produce the best drying results. Expandable FD-60 cover with 4 trays, but is expandable to 12 trays with optional Add_A_Tray . Opaque Vita-Save exterior helps block harmful light which destroys nutritional content of food being dehydrated. 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. Included with the food dehydrator is 5 jerky spices/cures, 1 fruit roll sheet, and informative care and use guide complete with handy drying charts and recipes. Refer to model No. LT-2W for Add-A-Tray .
