Because of its convenient use, microwave ovens do not produce the advantages of soot, and become a daily electrical appliance for many households to heat food. Nowadays, microwave ovens are very affordable, and they are very popular. Almost every household has it, but some consumers have not touched it or don’t know it very well. Let’s take a look at the usage of microwave ovens and microwave ovens. Precautions for use.

What is the usage of the microwave oven?

Before we get to know the usage of the microwave oven, let's first take a look at how it works. The microwave oven uses the ultra-high frequency microwave generated by the magnetron of the whole machine, which is 2.45 billion times per second, to quickly oscillate proteins, fats, sugars, water and other molecules in the food, so that the molecules collide with each other. , extrusion, friction rearrange the combination. In short, it is cooked by the principle of frictional heat inside the food itself.

1. The function of the microwave oven is now more and more. The microwave oven with single microwave heating function will discharge the cooling air of water vapor during cooking, generally does not affect the environmental cleaning. Such a microwave oven is placed in the kitchen, bedroom or living room without any major obstruction; and with barbecue function, light wave function, hot air convection The function of the microwave oven, when the cooking fumes will be discharged, it should not be placed in a room with high environmental cleaning requirements.

2. The method of using the microwave oven is very simple. After putting the food in the microwave oven, close the door and adjust the firepower size and time. The microwave oven should be placed on a flat, ventilated countertop or shelf. The distance between the back, top and sides and the siding is generally required to be more than 10 cm. The distance between the top of the microwave oven with grill function, light wave function and hot air convection function is at least 15 cm.

Microwave oven use precautions

Sometimes there are times when the microwave oven is used improperly and the user is injured. There are still many things to pay attention to when using it:

1, avoid overtime heating

Pay attention to the time when the microwave heats the food. The food is thawed or heated in a microwave oven. If you forget to take it out, if it takes more than 2 hours, you should throw it away to avoid food poisoning.

2, avoid heating ordinary plastic containers

Never put plastic in the microwave. First, hot food will deform the container. Second, ordinary plastic will release toxic substances, contaminate food and endanger human health.

3, avoid heating the meat to a half-cooked, then use a microwave to heat

The microwave oven is a heating function and does not cook the food. Because bacteria still grow in semi-cooked foods, and when heated in the microwave for the second time, it is impossible to kill all the bacteria due to the short time. Frozen meat must be thawed in a microwave and then heated to a cooked food.

4, avoid using metal utensils

Microwaves cannot penetrate metals. Because of the metalware such as iron, aluminum, stainless steel, enamel, etc. placed in the furnace, the microwave oven will generate an electric spark and reflect the microwave when it is heated, which not only damages the furnace body but also does not be cooked, and is also prone to fire.

5, avoid freezing the meat thawed in the microwave oven

Do not thaw food in a microwave oven. Because the meat is thawed in the microwave oven, the outer layer is actually heated at a low temperature. At this temperature, the bacteria can multiply. Although freezing can stop the reproduction, the live bacteria cannot be killed. Meat that has been thawed in a microwave oven must be heated to full ripe if it is frozen in the refrigerator.

6, the microwave should be placed in the safety. The microwave oven should be placed in a ventilated place, and there should be no magnetic substances in the vicinity, so as not to interfere with the uniform state of the magnetic field in the furnace chamber, so that the working efficiency is lowered. Also leave a certain distance from the TV and radio, otherwise it will affect the visual and listening effects.

8, the microwave can not be empty inside. Do not energize when cooking food is not in the oven. Do not allow the microwave oven to run at no load, otherwise the magnetron will be damaged. In order to prevent inadvertent operation and no-load operation, a glass filled with water can be built in the furnace chamber.

9. Microwave heating will expand the air inside the sealed product. Shelled eggs and foods in sealed packages cannot be cooked directly to avoid explosion.

While microwave ovens bring convenience to us, they also bring certain safety hazards, but there are certain dangers when using electrical appliances, so there is no need to be too jealous. As long as you pay attention to safety, you can use it properly. The use of the microwave oven introduced by Xiaobian and the precautions for the use of the microwave oven are also more detailed, I hope you can use it safely.
