The Excalibur dehydrator is everything you need to make a never-ending supply of wholesome & healthy dried fruit, healthy lunch box snacks, vegetables and meat dishes! The Excalibur dehydrator is the perfect choice to high-production gardening. Awesome Organics's Excalibur dehydrator is reputed to be the best dehydrator for preserving the nutrient & enzyme levels of living foods. The best way for retaining the enzymes is to set the Excalibur on 105F/40C setting throughout the entire cycle. That way the food temp will never go above 120F/48C even after it is dry.
