The most important part of the oven, the heating tube, is also very knowledgeable. Let's increase the "posture" together!
The knowledge in the heating tube (1)
Have you ever paid attention to the heating pipes of the oven at home? Except for the number of heating pipes, the heating pipes of the oven are basically straight pipes. Have you ever used a curved pipe oven?
Compared with the straight tube, the curved heating tube heats up more gently, and the heating area is larger when baking food. The linear heating tube is a 180-degree plane heat dissipation, while the curved heating tube can realize 360-degree three-dimensional heat dissipation.

What is the difference between the number of heating tubes in the oven: 4 and 6? Electric heating tubes are not better, because the power of the oven is generally fixed. The more electric heating tubes, the smaller the power allocated to each tube. Slow heating, increased preheating time, and reduced thermal efficiency are very unfavorable for foods that need to be roasted on a fierce fire. Therefore, the oven heating tube design should consider the baking effect. Generally, 6 tubes are used for ovens above 50L, and 4 tubes are used for 15-50L ovens.

The heating tube in the oven is generally divided into two types: quartz tube and metal tube. Quartz tube heating speed is faster, but it is easy to be broken and damaged, blackened, and has a short life. The life of metal pipes is relatively long, often copper pipes and stainless steel pipes. Copper pipes will produce patina after being used for a long time. Stainless steel pipes are divided into 304 pipes, 430 pipes, 840 pipes, and bluish pipes. But the most commonly used is stainless steel 430 pipes.
