The microwave oven can steam the whole chicken. When microwave is radiated to food, food always contains a certain amount of water, and water is composed of polar molecules (even when there is no external electric field, the positive and negative charge centers of molecules do not coincide), and the orientation of such polar molecules will change with the microwave field.

Due to the movement of polar water molecules in food. As well as the interaction between adjacent molecules, it produces a phenomenon similar to friction, which makes the water temperature rise, so the temperature of food also rises. The food heated by microwave is heated at the same time, so that the whole object is heated evenly and the heating speed is fast.

Using its internal magnetron, electric energy is converted into microwave, which penetrates food with an oscillation frequency of 2450MHz. When microwave is absorbed by food, polar molecules in food (such as water, fat, protein, sugar, etc. ) is attracted to oscillate at a speed of 2.45 billion times per second, and the macro performance of this oscillation is that food is heated.

Extended data

The safety accidents of microwave ovens are often caused by improper use. The following two types of accidents are the most common:

1, liquid overheating. When microwave heating, because water does not flow, but the temperature rises, it may "not open" when it exceeds the boiling point, leading to overheating. At this time, as long as the water is slightly disturbed, it will boil violently, which is prone to scald accidents. The cleaner the container and the cleaner the water, the greater the possibility of occurrence.

2. The egg exploded. The microwave oven can't heat the eggs, because overheating inside the eggs will generate more pressure, which may explode if it is released due to external interference.

Consumers should choose microwave ovens according to their own needs: if they only heat dishes and rice and thaw food, they can choose microwave ovens with single microwave heating function; If you usually cook in a microwave oven, you can choose a microwave oven with barbecue.

In addition, some microwave ovens on the market have electronic control devices, so you can cook the corresponding dishes by pressing the button on the control panel. Some microwave ovens have frequency conversion function, and the output power of electrical appliances is large at the initial heating stage, which improves the heating performance of electrical appliances.

In a word, consumers should choose a suitable microwave oven according to their own needs and the cost performance of their products, and should buy it in regular sales places to protect their own interests.
