Yes, I'm using a Lem, 10 tray dehydrator. I process the apples with one of those tools that peels, cores and slices all at the same time. Four gallons of apples off the tree will fill a one gallon plastic Ziplock bag and half of another bag when done. I make them very crisp - like potato chips. Sixteen hours at 150 degrees will do the trick. You can do plain or season before drying with cinnamon, brown sugar, etc....
