Can microwave ovens use metal containers to heat food?

Never put food in a metal cooker directly into the microwave oven for cooking, which will be very dangerous in serious cases.

On the one hand, because it is difficult for microwaves to penetrate metals, if the microwaves radiated into the air encounter metals such as steel during transmission, they will be reflected like light beams hitting the mirror, and the food in metal utensils cannot absorb the microwaves and cannot be heated. On the other hand, microwave can't penetrate metal utensils and can only be reflected in the furnace, which is easy to form a high-frequency short circuit of microwave energy, and even make the magnetron anode emitting microwave generate high temperature, burn red or even be damaged.

Precautions:

1. If you cook frozen food in the microwave oven, you should thaw it first. Thaw evenly with microwave low-power gear; For some foods with different thicknesses, in order to prevent some parts from being cooked, you can pause for a while before thawing; The food thawed at one time should not be too much or too thick. The thickness of meat food should not exceed 3 cm, and the thickness of other foods should not exceed 5 to 7 cm.

You can't fry food in the light wave oven. Generally, fried food needs to be heated slowly, and light wave and microwave heat quickly, which is prone to danger.

3. Avoid heating sealed canned food and bagged food with microwave oven, which may easily lead to explosion and rupture of sealed products, except for specially marked microwave food. If plastic wrap is added to the food container to prevent water evaporation, some small holes should be punched.
