Our "Top of the Line" unit! More powerful and larger than any other. Unit comes with four trays and expands to a giant 30 trays with the purchase of additional trays so you can dry large quantities all at once! 1000 watts of drying power means you can dry more, faster. Patented Converga-Flow fan forces heated air up 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 95-160 degrees F thermostat 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.
