Food dryers are also called dehydrator, drying oven, drying machine, fruit dryer, drying machine or drying device. These devices make it possible to slowly dehydrate (dry ) fruit, vegetables, herbs, meat, fish, etc., so that it can be kept for many times longer. But of course it's not just about shelf life. Drying fruit makes it easy to make delicious fruit leather or fruit chips. Yummy!
