How Do Low Fat Health Fryers Work?

When it comes to home cooking, air fryers are very much part of the latest trend. Thanks to their ease of use, as well as health benefits, an air cooking device can be a great addition to any home.

Of course, if you’re not familiar with these tools, you might not even know how they work! To help you, here’s a basic guide to how these pieces of equipment work, as well as what you should look for when buying such a product.


How Does Air Frying Work?

The actual science behind air frying can be quite complicated, but the core concept is simple. A traditional oil fryer uses lots of oil, heated to a very high temperature, to cook the food.

These new variants, on the other hand, use hot, controlled air environments to achieve the same results. Since a little oil is still needed, you still often need to add some, but most devices use a around a teaspoon of oil at the most.

Yet this reduction in oil helps make the same recipes much more healthier, while still retaining all the flavour that makes them popular. As such, these devices are firm favourites in many kitchens, especially when you want to eat better but don’t want to give up special meals.



Now you know what an air cooker does, what else does it need? Like any other kitchen appliance, there are a wide range of features you need to look out for. Some are important, while others are simply optional.



When it comes to capacity, there are two factors you should look out for. The first and most important of these is the food capacity. This is the amount of food that the cooker can hold. Typically, this is given in kilograms (or grams, if it is small enough) and represents the uncooked weight. It goes without saying that a bigger cooker can hold more food so, if you have more than one mouth to feed, a bigger option is better.

The second capacity feature, however, is the oil capacity. Although air fryers need only a minimal splash of oil to work, that doesn’t stop them working like conventional devices, either. If you want, you can still use plenty of oil and prepare food the traditional way. When it comes to this, these products give the capacity in terms of litres, telling you exactly how much oil can safely sit in the device.


Baskets And Bowls

Most fryers have both a basket and a bowl, allowing you to cook to your preference. A basket has no holes, so the oil is often added straight to the food. A basket, on the other hand, is lowered into the oil. This is commonly used with the likes of chips, for instance.

Likewise, the majority of kitchen appliances have removable baskets and bowls. This makes accessing the food much easier but, more importantly, it means these parts can be washed without damaging the electronic parts. In other words, you can keep the parts that make contact with your food clean by placing them in the dishwasher like any other piece of kitchen equipment.


Temperature Controls

Different recipes require different temperatures and this is no different when cooking with air. Yet the way temperature controls work can vary from one device to another. Some high-end models may have digital controls and pre-set values for specific types of foods, while others might just have a simple dial or crank for you to adjust.


Viewing Screen

In other devices, a viewing screen might seem a little unnecessary, but an air fryer works a little like an oven. You want to preserve the internal heat and pressure, so opening the compartment to check it is being cooked can actually be counterproductive – especially if its something you do often.

A viewing screen, then, makes perfect sense. This lets you keep an eye on you food without disturbing the overall process. Many products now have this as standard, as its a very subtle inclusion that can make a big difference.


Vapour Filter

Similarly, while not necessary, a vapour filter is something that can make such a device all the more practical. This filter helps reduce the amount of smoke and vapour that gets released from the fryer. This way, you don’t get too hungry smelling the food while you wait.

Likewise, it also makes the area near the cooker easier to be in. Without vapour in your eyes, for instance, it’s much easier for you to see and operate. Again, this is a small touch that makes for a very big improvement.



For some people, a decent timer is absolutely vital. Many pieces of equipment in the kitchen come with this as standard and, for the most part, this is still the case with these air products. However the type and effectiveness of each timer can vary. Some products use digital options, while some use traditional variants.

This all depends on your personal preferences. You might need something clear and loud, for example, if you like to leave the room while you cook. Some products even feature removable timers, so you can take it with you for the sake of convenience.


Fat Drainer

Part of the benefit of cooking with air is that it adds less fat (as there is less oil). Yet many people may still want the option of draining the fat away and, of course, many air cookers double as a regular oil fryer as well.

There are many different ways to drain fat. Some products actively do it during cooking, while others give you the option to do so afterwards. Of course, if you have a wire basket, then you can always leave your food to dry on an absorbent material (such as a paper towel). Other models may give you the option to rotate or tilt the bowl, allowing you to separate the fat and other juices as you please.

As you can see, there is a lot to consider about. However, if you want the best from your food, as well as a device that’s easy to use, it’s worth taking the time to understand what it is you want, before making such a purchase.
