The heating tube section of a baking tray is the core heating component, typically made of high-temperature and corrosion-resistant materials such as stainless steel or nickel-chromium alloy. It converts electrical energy into heat energy, evenly distributed at the bottom or sides of the tray to ensure uniform heating of food. The heating tube section features a compact design and high thermal efficiency, enabling rapid heating and maintaining a stable temperature, suitable for various cooking needs such as baking and grilling. Its surface is often treated with non-stick coatings for easy cleaning and maintenance, making it a crucial component of both household and commercial baking trays.
