Food dehydrators are wonderful for making fruit leather and beef jerky. Looking for one with a portable design? The Brod & Taylor Sahara Food Dehydrator is worth a look. It has over 11 square feet of drying area, stainless steel shelves, and digitally controlled 700w heaters. It folds to 1/3 its size in seconds.
This food dehydrator has automated time and temperature control. It is smart enough to run at a higher temperature for fast drying and switch to a lower temperature to maintain nutrients. You can set the timers for up to 198 hours.
