By the way, I will also talk about some things you need to pay attention to when using a microwave oven.

Working principle of microwave oven

Microwave oven uses microwave radiation for heating. Food generally contains a certain amount of moisture, and water is composed of polar molecules. This polarity The chemical molecules will change with the changes of microwave magnetic field. Polar molecules in food will interact with adjacent molecules, causing the water temperature to continue to rise, and the temperature of the food will also rise. When food is heated using microwaves, its interior will also be heated at the same time. The entire object will be heated more evenly and the temperature will rise faster.

How to use a microwave oven correctly

1. Before using a microwave oven, you should check whether the utensils used are suitable for microwave ovens.

2. Before cooking, you should put in the turntable support and glass turntable, and then place the filled food on the turntable for cooking.

3. When using a microwave oven to cook a small amount of food, pay more attention to prevent fire. At the same time, do not use the microwave oven to store any food.

4. When food is heated in simple containers made of plastic, paper or other materials, attention should be paid at all times to prevent fire.

5. If the microwave oven door is damaged due to collision or fall, do not continue to use it. It must be repaired by a professional before use.

Precautions for using microwave ovens

1. Do not heat meat until it is half-cooked and then reheat it in a microwave oven. In half-cooked food, bacteria will continue to grow and will not be used again. When heated in a microwave oven, the heating time is short and cannot kill all the bacteria, so the heated food can easily cause harm to the human body.

2. The microwave oven cannot be started when not in use to avoid damaging the magnetron when the microwave oven is running without load. When using a microwave oven to heat food, if the food catches fire, do not open the oven door. Once the oven door is opened, surrounding air will rush in, and the oxygen contained in the air will aggravate the spread of the fire. At this time, you should immediately turn off the power and unplug it. Just unplug the power cord and set the timer back to zero.

3. Do not use metal utensils when using a microwave oven to heat food. Iron, aluminum, stainless steel, enamel, etc. placed in the oven will generate sparks with the microwave oven and reflect microwaves during microwave heating, which will damage the furnace body. It cannot achieve the effect of heating food.

When using a microwave oven, you must first determine whether the material of the utensils placed in the microwave oven is acceptable. Metal utensils cannot be placed in the microwave oven; if they are paper and plastic utensils, they must be placed in the microwave oven. When heating, you also need to observe the temperature of the microwave oven to avoid high temperature fires in paper and plastic utensils. Some people think that using a microwave oven is dangerous. That is because you have not mastered the correct method of using a microwave oven. As long as you follow the strict operation of the microwave oven introduced by the editor, I believe you can learn to use the microwave oven in just a few minutes.
