While commonly used in commercial kitchens, household models are available and have become increasingly prevalent. Deep frying has become well fish batter for deep frying in the United States, from frying sticks of butter to Twinkies, but the method can be traced back to Roman times.
Deep fryers generally have a basket to lower the food into the oil tank and raise it when the food has finished cooking. Fryer baskets purchased separately are not standardized and when selected, need to fit into the deep fryer. The modern commercial fryer has improved energy efficiency, resulting from better heat transfer systems. Commercial fryers with infrared heating or convection heating are efficient, but often expensive. Electric restaurant fryers are popular in counter top models, because of their mobility and easy installation. They lose less heat than gas fryers, because their heating elements are immersed in the oil and have a faster temperature recovery time between frying cycles.
Gas fryers heat up more quickly and to a higher cooking temperature than electric fryers. Some commercial fryers have a “cold zone” at the bottom of the fry pot. This is where food particles, such as breading, batter or broken off pieces of food, sink to, while the lower temperature keeps them from burning and tainting the oil. A tube-style fry pot has a large cold zone because the tubes are slightly above the bottom of the vat, leaving generous space for cooler oil and crumbs.
Open fry pots have an external heat source, which makes them easier to clean and affords better access to the oil, but they generally offer a smaller cold zone, so food particles could pollute the flavor of the oil. However, these fryers work very well for lightly breaded foods. Some domestic fryers incorporate an angled motorized rotary basket that circulates its contents through the hot oil. This design reduces the amount of oil required to roughly half compared to a more traditionally designed fryer.
Domestic fryers are generally much smaller than their commercial counterparts and typically have a capacity of two to four liters. Temperature controls for deep fryers can be implemented, but are uncommon. Without them the deep fryer needs to be watched consistently to ensure safety. There sometimes are “computerized temperature controls” in fryers on the market today, especially in commercial fryers. Using these systems doubles the life of the oil. Deep fryer accessories are products that are designed to improve the process of frying.
A typical accessory of a deep fryer is the frying basket, which holds items to be fried and lets users take the food out of the fryer without using other tools. The automated deep fryer has a different system that incorporates a single basket unit or double basket unit, which could be useful in loading, cooking, and serving food. The refrigerated storage compartment has a portion controller and dispenser, a separate cooking chamber having a frying vessel. Most automated deep fryers include an air filtration system which gets rid of the greasy smell of fried foods. Since cooking foods at high temperatures in order to kill bacteria and pathogens is required, cautionary measures need to be taken into consideration.
One of these precautions is the use of water and other solutions around deep fryers because water or ice that meets hot oils is likely to gurgle, splash, and bubble onto nearby surfaces or objects.
