How to Use a Convection Oven As a Food Dehydrator

Updated February 21, 2017

You do not necessarily need a food dehydrator to dry food. A convection oven works well as a food dehydrator because its fan and convection cycle speed up the food drying process. Drying food in this way prevents the formation of bacteria, yeast and moulds by removing the moisture from the food. It also slows the enzymes that will eventually break down the components of the food.

Heat your convection oven to between 60 to 71.1 degrees Celsius.

Place the food to be dried on a baking tray so that the food edges are not touching and there is plenty of air circulation around the food.

Put the loaded baking tray into the convection oven.

Close the oven door or experiment with propping it open with a wood spoon for more air circulation.

Remove a piece of dried food from the convection oven, and let it cool before you taste it to determine its level of dryness.

Tip

The amount of time it will take to dry food in a convection oven will vary based on the water content of the food and the humidity in the air; however, it generally takes half as long as using a conventional oven.
