1. Is the design of the oil deep fryer heating element reasonable?
The heating tube is not easy to be damaged. First of all, it depends on whether the heating tube you buy is suitable for your working environment. Therefore, the general heating tube is non-standard custom, and it is impossible to have stock. It is based on the actual working environment and work. The temperature is used to design the surface load of the heating pipe, and the rationality of the surface load design directly determines the life of the heating pipe.
According to whether the heating medium is oil, the surface load of the heating pipe is generally designed according to the fluidity or staticity of the oil  is generally controlled at 0.7-1W/cm2. Since the ignition point and viscosity of oil are different from those of water, the recommended value of the surface load in the heating pipe manufacturing standard is relatively small.
So you can see from this point of view whether your heating tube design is reasonable. Generally speaking, there is definitely no problem with heating water with heating pipes for heating oil, but heating pipes for heating water are not necessarily suitable for heating oil.
2. Is the use of oil deep fryer heating element reasonable?
If the surface load design of your heating tube is reasonable, it depends on whether your heating tube is used reasonably, whether the heating area of the heating tube is immersed in oil, and if there is grease on the surface of the heating tube, is it cleaned in time?
Because dry burning will cause the surface temperature of the heating tube to be too high and burn out. In addition, if the surface of the heating tube is too oily, it will hinder the heat dissipation of the surface of the heating tube, so that the surface temperature of the heating tube is too high and it is easy to burn out.
