You can choose two different brands of microwave ovens, and then heat a food at the same time. Under the condition of ensuring that the food is cooked thoroughly, see which one takes shorter time. The shorter the time, the faster the heating speed of this product. When you buy, you should try to choose a microwave oven with faster heating speed, which will save time and electricity when using it.

Second, the power, electricity

When purchasing products, many users only look at the power and ignore the output power, and food heating will be affected by it. The greater the output power, the faster the food heating will be. In addition, turn the machine upside down and look at the input power behind the machine. Note that the smaller the numerical difference between the input power and the output power, the better. The smaller the difference, the greater the effective power of the machine and the more energy-saving.

Third, the bottom plate

Many consumers will make a common-sense mistake when buying microwave ovens, thinking that heating is faster with large volume, but ignoring the size of the bottom plate. In fact, the size of the bottom plate will affect the heating speed. For example, the larger the area of the bottom plate, the higher the heating speed, the higher the heat and the more uniform the food is heated. Only when the size of the bottom plate is the same, the larger the volume, the higher the thermal efficiency of the microwave oven.

Fourth, the small platform

Many users are unfamiliar with the small platform. There is a microwave payment device installed on the small platform, which is used to break up the microwave, so that the microwave can be transmitted evenly upward to heat the food. Note that the larger the small platform area and the closer it is to the bottom, the more flexible the agitator and the more uniform the food heating.
