We use the 1/16 setting on the mandoline to cut them so they are like sweet potato chips."

The mandoline assures uniformity of drying , when used with larger fruit/vegetables (apples,bannana, citrus,etc.).
Therefore , almost all dehydrated product gets done at the same time.
Also, you can dehydrate in season , and cheap frozen vegetables and fruits, especially if they are of a uniform size.
Dehydrated product will be approximately reduced to about 1/3 their normal size, be lighter in weight.
Dehydrated peas ,carrots , onions, and other root crops are sweeter in flavor as sweetness is condensed; especially true with citrus fruits and berries.
Size for travel can be further reduced by using a grinder ,or mortar and pestle and made into a powder , and placed in plastic freezer bags.
