Why does thickness affect dehydration time?

Thicker slices have more water content per piece, so moisture takes longer to migrate from the center to the surface. Uniform slicing (2–6 mm for most foods) gives consistent results.

Are these times safe for meat jerky?

USDA recommends heating meat to 160 °F (71 °C) and poultry to 165 °F (74 °C) before or after drying. The times shown assume a 70 °C (160 °F) dehydrator; finish in a 275 °F oven for 10 minutes if unsure.

Can I stack trays with different foods?

Yes, but use the longest time required by any item in the load and keep strong-smelling foods (onion, garlic) on separate runs to avoid flavor transfer.

How do I know when food is done?

The doneness test shown for each food is the most reliable guide. Weight loss alone is not sufficient — the texture check (leathery, crisp, or brittle) is the standard.

Does altitude affect drying time?

Yes. At elevations above 3,000 ft (915 m) add roughly 10–15 % to the estimated time because water evaporates at a lower temperature.
