The precautions and usage of microwave ovens are as follows:

1. How to use microwave ovens:

The microwave oven must be used in a stable and ventilated place, and the rear part should be left There should be no less than 10 cm of space and no less than 5 cm of space at the top. When using the microwave oven, keep away from other household appliances with magnetic fields to avoid affecting the use effect.

When using a microwave oven, do not place food directly on the turntable, but use containers made of heat-resistant glass, ceramics or heat-resistant plastic. Absolutely no metal or enamel containers should be used, and containers with metal patterns should not be used. Because contact between microwaves and metal will produce sparks, which is dangerous and may even damage the magnetron in severe cases.

2. Precautions:

The microwave oven should be placed in a dry and ventilated place to prevent heat and water vapor from entering the microwave oven. There should be more than 15cm of ventilation space around the microwave. Do not heat meat until it is half-cooked and then reheat it in a microwave oven. Bacteria will also continue to grow in half-cooked food.

Use the microwave to heat again. Its heating time is short and cannot kill all the bacteria. Generally, when heating food, frozen meat products need to be defrosted in the microwave oven and then reheated into cooked food.

Food that cannot be put into the microwave oven

1. Avoid heating the meat until it is half-cooked and then heating it in the microwave oven: because bacteria will still grow in the half-cooked food, it will not be used the second time. When heated in a microwave oven, it is impossible to kill all bacteria due to the short time. Frozen meat products must be defrosted in a microwave oven before being reheated into cooked food.

2. Avoid refreezing meat that has been thawed in a microwave oven: after the meat is thawed in the microwave oven, the outer layer of the meat has actually been heated to a low temperature, and bacteria can breed at this temperature. Although refreezing can stop reproduction, it does not kill living bacteria. Meat that has been thawed in the microwave must be heated until fully cooked if placed in the refrigerator.

3. Avoid fried foods: high-temperature oil will splash and cause fire. If a fire accidentally breaks out in the furnace, do not open the door. Instead, turn off the power first and wait until the fire is extinguished before opening the door to cool down.
