How to choose the heating tube for the oven?

Home    更新    How to choose the heating tube for the oven?

The heating tube of the electric oven is very important. The function of an oven is to generate high temperatures to bake or dry things. The heating devices commonly used in general electric ovens are stainless steel heating tubes, resistance wire (electric heating wire) heaters and quartz heating tubes.

 

Let's take a look at the advantages of three electric heating tubes.

 

1. Quartz heating tube: generally use radiation to heat the object, the heating is relatively uniform, and it does not touch the heated object, but it is difficult to heat locally; while the stainless steel heating tube is heated by heat conduction, which heats quickly and is not easy to be uniform, but can be heated locally. .

 

It can be said that the quartz tube heats up quickly, but the temperature drops quickly after the power is turned off, the life of the quartz tube is also short, and the impact resistance is also poor. That is to say, it will be damaged when touched, and the radiation ability is worse than that of far-infrared heating tubes.

 

2. Only the resistance wire has the worst heating effect. Stainless steel heating tubes are the best heating elements. .

 

3. The best oven heating elements belong to far infrared heaters, but far infrared heating tubes are much more expensive than the above three electric heating tubes. If the quantity is small, you can use the far infrared heating tube regardless of the price.

 

Among them, the stainless steel heating tube has the highest efficiency and is more convenient to replace and maintain. The other two have been used before, but are rarely used now, and the efficiency is not as high as the first.
