Type of electric oven heating tube:
The commonly used heating devices for electric ovens are three types: “quartz far infrared heating tube”, “resistance wire (electric furnace wire) row heater” and “halogen heating tube”. Among them, quartz far infrared heating has the highest efficiency and safety. The coefficient is also relatively large, and it is relatively convenient to replace and repair, so it is the most used and most common one. On the contrary, the other two have been used before, but now it is rare, and the efficiency is not the first. Generally, the heating devices in the microwave oven with a grill are mostly quartz far infrared heating tubes.
Precautions for using the heating tube of the electric oven:
1. Preheat the oven.
Before baking any food, the oven must be preheated to the specified temperature to meet the baking time on the recipe. It takes about 10 minutes for the oven to warm up. If it is not enough, it may not reach the specified temperature. If the oven is preheated for too long, it may affect the service life of the oven.
2. baking height.
Bake things in a small oven, basically just put the food in it, but the medium-sized oven usually has three layers of upper, middle and lower heights. As long as the recipe does not specify the temperature of the fire, the baking tray will be placed. In the middle layer; if the ignition temperature is high and the ignition temperature is low, unless the oven is up and down, the temperature can be adjusted separately. Otherwise, the upper and lower fire temperatures are usually divided by two, and then the baking tray is placed on the upper layer. You can, but you still need to keep an eye on whether the surface is over-focused.
