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.

Aluminum heating tubes have a high heating efficiency. Due to its good thermal conductivity, after the power is applied, the electrical energy is quickly converted into heat energy and conducted inside the heating tube, and then evenly transferred to the surface of the baking sheet. This efficient heating method results in a more uniform temperature distribution on the surface of the baking pan, reducing the risk of local overheating or undercooking. For example, when grilling Korean barbecue, the meat slices can be evenly heated on the baking sheet, resulting in a better texture and more uniform color.

Stainless steel heating tubes have many outstanding advantages. Firstly, the material is excellent, using high-quality stainless steel with super strong corrosion resistance. Whether in humid environments or in contact with acidic and alkaline liquids, it can operate safely and ensure long-term stable operation, greatly reducing maintenance costs. Secondly, it has extremely high thermal efficiency, generates heat quickly, and can quickly raise the temperature to the ideal state, effectively saving energy and achieving efficient heating. Thirdly, it has outstanding mechanical performance, strong compressive and seismic resistance, and can be flexibly installed in various complex equipment, such as industrial ovens, heaters, water heaters, etc. Fourthly, it is safe and reliable, with excellent insulation performance, which can effectively prevent potential leakage hazards and ensure safe use. Fifthly, it is easy to clean, with a smooth and flat surface that is not easily adhered to by stains and scale. With a gentle wipe, it can shine as bright as new, maintaining good heating performance and providing users with a convenient, efficient, and long-lasting user experience

The heating tube is the "heart" of the oven, responsible for converting electrical energy into heat energy and then evenly transferring it to the food. Its performance is directly related to the oven's heating efficiency, temperature uniformity, and the final cooking effect.

The heating tube, as the heating core of the coffee machine, has a simple basic structure, but contains exquisite design wisdom. It is mainly composed of three parts: heating wire, metal tube and insulating material. The heating wire is like the "heart" of the heating tube. It is the key part for converting electrical energy into thermal energy. It is usually made of alloy materials with high resistivity. When current passes through, the heating wire will quickly heat up and provide a power source for subsequent heat conduction.

Small size: Adapts to the compact design of small hanging steamers, which is easy to install in limited space. The diameter and length of the heating tube of common small hanging steamers are relatively small. For example, the diameter may be around 10-20 mm, and the length varies from 100-300 mm depending on the specific model.
Power adaptation: The power is generally between 1000-1800 watts, which can not only meet the needs of rapid steam generation, but also adapt to the power supply and heat dissipation capacity of small hanging steamers, achieving a balance between efficient heating and energy saving. For example, the power of the heating tube of some portable handheld hanging steamers is about 1200 watts, which can heat water into steam in a short time.
Diverse voltage: There are many options for working voltage, the common ones are 12V, 24V, 220V, etc. Among them, 12V and 24V have lower voltages and higher safety. They are suitable for some rechargeable or portable small hanging steamers and can be powered by an external power adapter; 220V voltage is suitable for small hanging steamers powered by ordinary household power sockets.
Various shapes: Common shapes include straight tube, U-shaped, spiral, etc. The straight tube heating tube has a simple structure and is easy to manufacture and install; the U-shaped heating tube can increase the heating area in a limited space and improve the heating efficiency; the spiral heating tube further increases the contact area with water, making the heating more uniform and faster.
