Which Heating Tube is Better for the Oven?
There are usually four types of heating tubes for ovens: stainless steel heating tubes, quartz tubes, halogen tubes, and infrared light heating tubes. But which kind of heating tube is better?
1. Stainless steel heating tube: The outer surface is gray-black stainless steel that has been blackened. This is why we see the heating tube in the oven is black. Don't think it is dirty. Between the outer surface body and the heating wire is an insulation layer of magnesium oxide powder.
2. Quartz tube heating tube: The outer surface of the quartz tube heating tube is a quartz tube with a larger diameter. The outer surface and the heating wire are directly air barriers. The power of a single quartz tube is greater than that of a single stainless steel heating tube; Low, fast roasting speed, but the life span is usually relatively short, and the quantity used in the oven is small.
3. The halogen heating tube, the heating element is tungsten wire, the sealed tube is filled with inert gas, and the main component of the emitted light is strong visible light, which breaks the energy of the ordinary electric heating tube from the heat special line medium to the air, and then to the food The way of delivery. Realize the direct transfer of energy from light energy to food. Baking food is faster.
4. Infrared light heating tube, infrared light heating tube, similar in appearance to quartz heating tube, the special feature is that the wall of the quartz tube is coated with infrared coating, the light component is mainly infrared light, and it is baked The speed of food is faster than that of ordinary quartz tubes.
Compared with the quartz tube, the stainless steel heating tube has a small power and a large amount. The food is cooked slowly, but the burning color is more uniform. When the length of the oven cavity is too long, the stainless steel heating tube must be used. The temperature of the quartz tube rises rapidly, and the effect of scorching the food surface is the best; but because it is made of glass, it is easy to break during transportation, so quartz tube is rarely used as a heating tube.
