Understanding the Role of Oven Heating Elements in Commercial Kitchens
The heating element in a commercial oven is responsible for generating the heat to cook food. Usually, these components produce heat using gas or electricity depending upon the type of oven. In electric ovens a coil or metal strip that heats up as an electric current passes through it serves as the heating element. Because gas ovens use a burner, the fundamentals of heating are still the same. A properly operating electric oven heating element is necessary to provide consistent cooking results in a commercial kitchen where timing and consistency are particularly important. The entire kitchen may be affected by a heating element failure, which could result in extended cooking times, uneven temperatures, or even an oven shutdown.
