Domestic or industrial fryers - what should you pay attention to?

We have already mentioned these two categories into which deep fryers are divided. To find out which one is right for you, you will probably have to answer questions such as: do you have a business, do you need to cook very large portions for many people, do you have space for a large fryer, do you have a large fryer?

If your answers are all negative then you need something smaller and for home use. But for the avoidance of doubt, let's dig a little deeper into these points. Below we will understand in detail what each one is about.

Domestic. Household appliance manufactured for frying food. Their capacity is limited, designed only to meet the needs of a household. They are more economical and compact models that adapt well to the spaces of a house.

Industrial. These are professional fryers for heavy-duty use and high performance. They satisfy large portions of food thanks to their larger capacity. They are known as "floor fryers". They are used in restaurants, hotels, bars, food trucks, bazaars, etc.

Types With oil, without oil, water and oil Gas, electric, high performance, pressure
Heat source Electric, Gas, Convection or infrared Electric, Gas, Convection or infrared
Capacity From 1 to 5 litres From 4 to 35 litres
Temperatures From 80 to 200°C From 100 to 220°C

Are there varieties of domestic deep fryers?

Oil fryers. Most of them are electrically powered. They heat up quickly due to their heat source, which makes it very easy to achieve a crispy finish on food. They are easy to use and come in different sizes and designs.

Oil-less fryers. Although they are known by this name, they do use a little oil (1 teaspoon), especially if you are looking for that crispy touch in your food, but they also take advantage of the natural fat generated by cooking to continue cooking. The low use of oil makes it a much more natural and healthy option.

Water and oil fryer. This is an appliance that works with a heating element, water and oil. This combination ensures that the food cooks quickly, but without mixing flavours, even when cooking different types of food at the same time. It also has a drain tap to get rid of waste water.

Buying criteria

We know you're almost with one foot in the shops, but don't leave without this information because it's vital. The buying factors we are about to mention are a guide to help you understand what things to consider before making a final decision, so pay attention.


It is important to take into account how many people on average you need to feed with the fryer, as this will determine the capacity and therefore the model you should choose. As already mentioned, domestic fryers have capacities ranging from 1 to 5 litres. Models can also handle portions or per kilogram of food.

For example, for family gatherings it is recommended to choose an intermediate model with a capacity ranging from 800 kg to 1,200 kg or 3 to 5 litres, but if it is for a single person or a couple, a 1 litre fryer may be sufficient.


This is a very important feature in the appliance, as it will be in charge of regulating the temperature at which the food will be cooked. Some appliances include an alarm and you can program both the thermostat and the alarm, letting the fryer work by itself and letting you know when the cooking time has been reached.

The temperatures that the fryers can reach range from 80°C to 200°C. It is recommended that once the oil is hot, the fryer manages to maintain the temperature at around 160°C, as if the temperature is higher we could burn the food.


The power of the appliance is directly related to the temperature, the more power the fryer has, the higher the temperature it can reach. Check the specifications of the product, you can find options ranging from 800 to 1350 watts.

The minimum recommended power for an electric fryer is 1000 watts, and for an air fryer it is 2000 watts. Also note that an oil-less fryer will take longer to cook the food because of its cooking system.

Safety System

Just as we want to avoid burns with frying pans, and although deep fryers are safer, there are also some important safety systems that will prevent us from any accident or food burning, some of them are:

Thermostat. This point avoids fluctuations in temperature. When there is a thermostat and it works correctly, the temperature can be kept stable and it is even activated if there is a problem of overheating.

Transparent or windowed lid. Not all fryers have this function but it is a plus, as it avoids splashes that could burn us. With an added advantage, it allows us to observe how the cooking of our food is evolving.

Automatic shut-off. Including this function will guarantee that the food will not overcook, as once it is ready, it will automatically switch off, as if that were not enough, it helps us to save energy
