The STX Dehydra 800W Model STX-DEH-800W-XLS 10 Tray Food and Jerky Dehydrator with 40 Hour Auto Shut Off Timer features brilliant Digital Controls, 10 FDA Approved Bisphenol A (BPA) Free Drying Trays, 800 Watts of Drying Power, a 3 Drawer Front Blank for Making Yogurt or Raising Bread and 2 100% FDA Approved 41 Mil Silicone Mats for Making Fruit Leathers or Fruit Roll-Ups. This Extra Large dehydrator displaces 5,275 cubic Inch of drying space. With 1.75 Inches of height between trays, this STX dehydrator allows for larger cuts of Fruits & Meats on each tray. The STX drying trays with overall dimensions of 15 " X 13.5" feature Diamond Grid Design openings (7/16 " X 7/8") virtually eliminating the need for polyscreen tray liners. . The STX 800W Dehydrator drawers have a Heat Retaining Lip Design that eliminates the need for a bulky front panel door. With this feature, you can easily check the status of a tray of your dehydrating food or jerky without exposing the entire dehydrating area thereby preventing excessive loss of drying heat and processing time. The STX Horizontal Air Flow System features a 7 inch fan and heater located at the back of the dehydrator and generates a more consistent circulation of heat throughout the entire interior of the unit rather than forcing the heat up through layers of drying trays like circular/stackable dehydrators. Our 100% SAFE FDA Approved 41 Mil Silicone Mats (NOT TEFLON) can also be used as baking mats. Silicone is a natural product found in our environment and is considered a safe product with no toxic side effects. These mats can be used safely with oven temperatures up to 500 degrees (F) and your cookies, meats, etc. virtually slide off. They can be washed with soap and water, rolled up, stored and used hundreds of times.
