A deep fryer is an appliance used in the kitchen "Kitchen (room)") to fry food. There are industrial versions, as well as domestic variants.
There are also so-called oil-free fryers or hot air fryers. These, as their names indicate, allow frying, cooking and even baking (depending on the model) with the use of very little or no oil.
Characteristics
Modern fryers have a basket to remove food from the oil and drain it. They may also include timers with audible alarms, automatic mechanisms to raise and immerse the basket in the oil, a device to prevent flour and batter residue from burning at the bottom of the bucket, ventilation systems to mitigate odor, oil filters to extend their useful life, and mechanical or electronic temperature controls.
Types of fryers
They are high-performance fryers, very powerful with which you can cook countless foods. They have thermostats to calibrate the power. They are very safe equipment and prepared to perform with a high volume of work, which reach high temperatures in a matter of seconds.
Construction
Modern fryers have improved energy efficiency thanks to improved heat transfer systems. Commercial models with infrared or convection systems are efficient but expensive, which is why electric or gas fryers are more common.
Electric models are popular in the domestic market for their mobility. They lose a little less heat than gas ones because the thermal elements are submerged in the oil, and they have a shorter temperature recovery time between frying cycles. Gas models heat up more quickly and reach higher working temperatures, and can be powered by natural gas or propane, energy sources that are generally cheaper than electricity, making these fryers more popular in industrial environments.
Professional fryers are usually made of mild steel or stainless steel, the latter being more resistant to corrosion and stains. In addition, mild steel also expands more with heat, which can damage the appliance over time.

Gas models heat up more quickly and reach higher working temperatures, and can be powered by natural gas or propane, energy sources that are generally cheaper than electricity, making these fryers more popular in industrial environments.
There are fryers with a wide variety of buckets. Some models have a "cold zone" at the bottom of the bucket, where the pieces that come off the food are deposited, thus preventing them from carbonizing and dirtying the oil. Fryers with tubular heaters have a large cold zone because the tubes are slightly elevated from the bottom of the bucket, leaving a generous space for cooler oil. This is particularly useful when frying heavily breaded or battered items. Fryers with tubular heaters are more difficult to clean than open fryers, but they allow better access to the heat source and are usually less expensive. Open bucket models have an external heat source, which makes cleaning more comfortable and gives better access to the oil, but they usually have a smaller cold zone, so the particles that come off can burn and dirty the oil. However, these fryers work very well for lightly breaded foods. Flat-bottom fryers, a variant of open-bowl fryers, can also be difficult to clean and lack a cold zone, but they are very effective for frying dough.
Temperature control
Many modern fryer models include electronic temperature controls, which save energy by constantly monitoring and adjusting oil temperature. A high-quality thermostat can maintain the temperature within a range of 200°C, ensuring precise frying times. Safety thermostats that automatically cut off power if oil reaches dangerous temperatures help prevent fires.
Oil filtering
An oil filtration system, chemical treatment or diatomaceous earth powder helps remove small food particles that are not always visible. The use of these systems doubles the life of the oil. Filtering systems can be found to be purchased integrated into the fryer to avoid manually performing the relatively dangerous process of filtering the oil into an external system. Many restaurants use a portable filter system or shortening shuttle to transport waste oil to a disposal area. However, even old oil is not completely useless. There are methods (chemical and mechanical) to "recycle" used oil as biodiesel suitable for diesel vehicles.
Accessories
Industrial fryers have a wide range of accessories and options. There are built-in, floor and battery models with multiple floor units, filter systems and tanks united into one large frying system. Individual fryers can have one or more tanks. Industrial floor models may have wheels to facilitate maintenance and cleaning. Baskets are also available in various shapes and sizes, with or without heat-resistant handles.
Fire Hazards and Personal Safety
Since cooking foods at high temperatures is necessary to kill bacteria and pathogens, precautionary measures must be taken. One of these precautions is the use of water and other solutions around fryers because water or ice encountered with hot oils is likely to gurgle, splash, and bubble on nearby surfaces or objects. In fact, using water or ice with hot oil can cause the water to evaporate at that elevated temperature, causing serious bodily injury or hot explosions. This is commonly known as the flash point and should always be avoided. It is always better to use a chemical agent such as a fire extinguisher or cover the oil with a non-porous object such as a metal lid or tray rather than liquids such as water. Another precaution to keep in mind when using a deep fat fryer is to ensure that oil does not overflow when food is placed in the fryer and that the food can be completely submerged to ensure even cooking, especially for large items like turkey. If oil encounters flames, from stove burners and other sources, the results can be deadly as heated or gaseous oils can explode at nearby workstations and cause wall and ceiling fires. Another factor that can cause oil fires is the environment surrounding the fryer, such as keeping the work area free of objects and placing hot oil containers/fryers on smooth surfaces so they do not spill. Additionally, carbon monoxide can be created from deep frying and poor ventilation/airflow can cause people in the area to become poisoned, which is especially dangerous, so carbon monoxide detectors should be kept working.
