Air Fryer Vs Dehydrator: Similarities And Differences

Sometimes we get confused about the difference between an air fryer and a food dehydrator. Although these two kitchen appliances have similarities but these are different in many aspects. In this article, we will present a side by side differentiation between these two so that the reader can understand the right utility of these important kitchen companions.

basics of air fryer and dehydrator

Before I go into deep, let’s find out what are these kitchen appliances that I am going to differentiate.

What is a dehydrator?

A dehydrator is a kitchen appliance that is used to remove moisture from the food. Fruits and vegetables contain 50 to 90% water in it. Water acts as an essential element for the growth of bacteria and fungus. Therefore, a dehydrator is used to remove the water content from the food so that it can be preserved for a long time.

What is an air fryer?

An air fryer is similar to a convection oven that blows hot air to cook food without needing a lot of oil. It is a popular kitchen appliance that gives a crispy surface to the food. An air fryer can also bake, grill, and even roast food.

Working Principle of air fryer and dehydrator

Now as you have got a simple idea, let us find out the basic working principle of an air fryer and a dehydrator.

How does an air fryer work?

There is a heater on the top of the air fryer that generates heat. A blower fan circulates the hot air at the bottom. Hot air circulates on the food evenly to ensure the crispiness. It creates a brown outer layer on the food. There is an exhaust system that gets out the unwanted gases. The working temperature of an air fryer varies between 175 to 400°F. It can be used as a dehydrator only when there is an option to run this machine at a temperature lower than 200°F. This is the common working principle of an air fryer.

How does a dehydrator work?

In a dehydrator, there are several food trays where different kinds of foods can be dried simultaneously. These can be circular or rectangular. The circular dehydrators may rotate the food tray to ensure uniform heating. A dehydrator normally does not produce a lot of heat. It produces mild heat from 100 to 150°F so that the structure of the food does not get ruined. Because it needs to be heated at a low temperature, the whole process may take several hours to complete.
