How is a freeze dryer different from a dehydrator?

A freeze dryer freezes the food and removes ice by sublimation, which keeps shape, color and nutrients better. A dehydrator uses heat and airflow, is faster and cheaper, and gives a chewier result suited to jerky.

What can I dry in five trays?

Small batches: sliced fruit, vegetables, herbs, jerky and single-serving meals. Expect to run several batches to put up a real surplus.

Does the timer shut the unit off automatically?

The timer sets the run length, so you can start a cycle and let it finish without standing over it. Check the food at the end, since drying time varies with thickness and moisture.

Do I need to rotate the trays?

Vertical airflow moves air up through the stack, which helps even drying. Thicker pieces or a full load may still need a tray swap partway through.

Is it worth it over a larger freeze dryer?

If you preserve small amounts and have limited counter space, the compact size and simple controls make sense. For large harvests or frequent batches, a bigger unit will save you cycles.
