HOW TO SUN-DRY FOOD

This old-fashioned method of drying food requires heat from the sun and plenty of natural air circulation.

Get started by trying thinly sliced apples. The time it takes to dry the apples varies depending on the humidity in the air and the heat from the sun. At 70 degrees with dry, sunny weather, it takes about two days.

Cover your dehydrator at night or bring it inside to avoid dew getting on it.

    referring to the sides, top, bottom drawers and door. I see how big they are supposed to be, but those numbers that come before the measurements, are those referring to the number of each piece needed?
