Nesco FD-1020 Gardenmaster Digital Pro Food Dehydrator... Our \"New Digitally Controlled\" unit! Top mounted fan eliminates liquids dripping into the heater chamber. Expands to a giant 20 trays so you can dry large quantities all at once! 1000 watts of drying power means you can dry more, faster. Patented Converga-Flow forces heated air down the exterior pressurized chamber, then horizontally across each individual tray, converging in the center, for fast, even and nutritious drying. No flavor mixing! No need for tray rotation. Fast, Powerful Fan! A quiet, 2,400-RPM motor and specially designed 4-1/2 inch fan mean faster, more nutritious drying. Four times faster than dryers which have no fan or motors. Adjustable Thermostat! Different foods need different temperature settings. The adjustable 90-160 degree F digital control gives you the flexibility to get the best results. Vita-Save Exterior! The opaque exterior blocks light to retain more of the food\'s nutrients and vitamins during the drying process. Expandable to Meet Your Needs!
