How Ovens Work

The working principle of ovens mainly involves generating heat energy through heating elements and distributing the heat evenly in the baking space through air flow. Different types of ovens may work in different ways:

Traditional and modern ovens: Traditional ovens may use wood or coal as the heat source, while modern ovens are mostly powered by electricity or natural gas. These heat sources work by heating internal heating elements (such as resistance wires or gas burners).
Electric and gas ovens: Electric ovens are heated by resistance wires, while gas ovens use gas burners to produce flames or high-temperature smoke. This heat is used to heat the air in the baking chamber.
Hot air circulation: Many modern ovens have hot air circulation functions, which are achieved by built-in fans. The fans circulate the hot air in the baking chamber to ensure that the food is evenly heated.
Special types of ovens: For example, ferroalloy ovens, which produce high-temperature smoke through burners. These smokes mix with cold air and react at high temperatures to form hot air for baking. The vacuum baking oven uses a vacuum pump to extract air and moisture, forming a vacuum state, lowering the boiling point of water, thereby speeding up the drying speed.
