First, oven preheating means that before baking any food, the oven must be preheated to a specified temperature to meet the baking time in the recipe. It takes about 10 to preheat the oven. If it is insufficient, the specified temperature may not be reached. If the preheating time of the oven is too long, it may also affect the service life of the oven. Preheating is to turn on the oven 5- 10 in advance before baking food, turn the knob to the specified temperature and let it burn for a while. This is preheating. Unlike microwave ovens, ovens can burn in the air. Better ovens have temperature indicators. When the temperature reaches, the light goes out.

Secondly, if you want to bake a cake, it is usually preheated to 180 degrees, so you should set the oven temperature to 180 degrees in advance. The average oven can wait for 2 or 3 minutes. When you see that the temperature of the oven is rising, you can put the cake materials in and bake them. The purpose of preheating the oven is that when baking some food, the material will not go through a slow heating process and affect the quality of the finished product.

1, plug in the power plug; Turn the change-over switch to full load, that is, heat up and cool down at the same time, and turn the thermostat to the required temperature position. After a certain period of time, the indicator light goes out, indicating that the oven has reached the preheating temperature.

2. Put the baking tray with the handle fork into the oven. When automatic timing control is needed, screw the timer to the preset baking time; If automatic timing control is not needed, turn the timer to the "long connection" position.

2. The heater of the electric oven has a certain thermal inertia, and it takes 2-3 minutes for the surface of the heater to reach the normal working temperature when it is electrified; When the power is cut off, it takes some time to cool down. Knowing this characteristic of the heater is convenient to turn on or off the power supply of the heater in advance according to the baking degree of food.

Be sure to preheat the oven before putting the food in it. Because of the heat dissipation of the oven door, the baking degree of food near the oven door is always slightly weak. In order to bake the food evenly in all parts of the baking tray, you can turn the baking tray in the middle of baking and then continue baking.

In order to use electricity safely, the electric oven should have a good grounding wire. After each use, the electric oven should be wiped clean after cooling.
