How often should you rotate a dehydrator tray?

It's recommended to rotate dehydrator trays every few hours during the drying process to ensure even airflow and consistent drying. This is especially important when using a dehydrator with multiple trays, as the items on the top may dry faster than those on the bottom. If your dehydrator has a fan, rotating may be less critical, but it can still help achieve uniform results. Always refer to the manufacturer's guidelines for specific recommendations.
