The NESCO FD-1018A Gardenmaster Pro Food 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 eight (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. Includes eight fruit roll sheets, eight clean-a-screens, a sample of jerky seasoning & cure to get started, and a recipe & instruction book. The NESCO FD-1018A Gardenmaster Pro Food Dehydrator provides the drying power that generates maximum speed and quality for dehydrating your favorite fruits, vegetables, herbs and jerky.
