Let’s take a closer look at the technology behind a FLAMA Oil-Free Air Fryer and understand how it can prepare crispy, delicious food without the need for excessive oil. Let’s uncover the secret behind this revolutionary appliance in Portugal.
The Basic Principle of Air Fryers

The FLAMA Oil-Free Air Fryer operates on a simple yet effective principle: hot-air circulation. Inside an Oil-Free Air Fryer, you will find a powerful heating element and an internal fan. Let’s examine the steps in the process:
-
Rapid Heating
When you switch on the Air Fryer and set the desired temperature, the heating element starts heating the air rapidly. This is essential for creating the ideal cooking environment. We recommend preheating for better results.
-
Air Circulation
The internal fan starts operating, circulating hot air at high speed inside the cooking chamber. In FLAMA Oil-Free Air Fryers, this hot-air flow is distributed intelligently and evenly around the food inside the Air Fryer basket, producing excellent results.
-
Convection Cooking
The cooking process in an Oil-Free Air Fryer is known as “convection cooking”. Convection is the movement of heated air that transfers heat to the food. This ensures that food is cooked evenly, while the high temperature creates an irresistibly crispy surface.
-
Maillard Reaction
The high temperature and hot-air flow trigger the Maillard reaction on the surface of the food. This reaction is responsible for giving food the characteristic golden color and flavor associated with traditional results, without the need for immersion in oil.
-
Crispy and Delicious Results
The final result is a dish that is crispy on the outside and tender on the inside, very similar to what you get when frying traditionally, but with a drastic reduction in oil use—or even no oil at all.

Comparison with Other Types of Fryers
It is important to highlight how an Air Fryer works differently from other types of fryers, such as conventional fryers. With Oil-Free Air Fryers, we can achieve results that are very similar to conventional frying, but in a much healthier way.
