Precautions For Using The Heating Tube Of An Electric Oven
The heating devices commonly used in general electric ovens include "quartz far-infrared heating tube", "resistance wire (electric stove wire) row heater", and "halogen heating heating tube". Among them, quartz far-infrared heating has the highest efficiency and safety. The coefficient is also relatively large, and replacement and maintenance are relatively convenient, so it is the most used and most common one. On the contrary, the other two have been used before, but now they are relatively rare, and the efficiency is not as high as the first. Generally, the heating devices in the microwave oven with barbecue are mostly quartz far-infrared heating tubes.
Precautions for using the heating tube of an electric oven:
1. Preheat the oven.
Before baking any food, the oven needs to be preheated to the specified temperature to meet the baking time stated in the recipe. It takes about 10 minutes for the oven to preheat. If it is insufficient, the specified temperature may not be reached. If the oven is preheated for too long, the service life of the oven may also be affected.
2. Baking height.
Use a small oven to bake things, basically just put the food in, but medium-sized ovens usually contain three levels of upper, middle, and lower heights to choose from. As long as the recipe does not specify the upper and lower fire temperature, set the baking tray If the upper and lower heat temperature is high and the lower heat temperature is low, unless the upper and lower heat of the oven can be adjusted separately, otherwise, the upper and lower heat temperatures are usually added and divided by two, and then the baking pan is placed on the upper level. Yes, but you still need to pay attention to whether the surface is over-focused.
