The NESCO FD-1010 Gardenmaster Pro Dehydrator is our top of the line unit-more powerful and larger than any other. 1000 watts of drying power means you can dry more, faster. This dehydrator comes with four (15 1/2? diameter) trays and expands up to 30 trays so you can dry large quantities at once, with no tray rotation needed. Additional Add-A-Trays sold separately. The adjustable temperature control (95°F -160°F) gives you the flexibility to achieve the best results when drying different foods that need varying temperature settings. The quiet, powerful Converga-Flow® fan forces heated air up the exterior pressurized chamber, then horizontally across each individual tray. The air flow then converges in the center for quick, consistent drying that is four times faster than other dehydrators. The NESCO FD-1010 Gardenmaster Pro Dehydrator provides the drying power that generates maximum speed and quality for dehydrating your favorite fruits, vegetables, herbs and jerky.
