How to choose convection oven heating element?
Convection oven heating element is the heart of electric ovens. At present, most electric ovens on the market use tubular electric heating elements and quartz glass heating tubes. When buying an electric oven, you must pay attention to it, otherwise, if you buy a bad product, the heating tube will soon be broken. What should I pay attention to when purchasing?
Take a look at the characteristics of both:
1. Tubular electric heating element: The shape of the electric heating tube is rod-shaped, U-shaped and W-shaped, and the structure is relatively firm. The heating wire in the tube is spiral, which is not afraid of vibration and oxidation, and its life span can reach more than 3000 hours. If the far-infrared coating is applied to the surface, the thermal efficiency can be increased by 20-30%.
2. Quartz glass tube heater: It is milky white with a spiral electric heating wire with whiskers on the inner surface. The function of the beard is to make the heating wire in the middle of the glass tube, promote uniform temperature on the surface of the tube, and emit effective infrared rays. The quartz glass heating tube has a clean surface, small heat capacity, fast heating, and a life span of up to 4000 hours. However, it has low mechanical strength and is easily damaged during transportation. So when you buy, you must look carefully.
To avoid buying the wrong electric oven, choose the wrong heating tube. Before purchasing, it is necessary to further understand the relevant knowledge of the conveying oven heating element.
