The remaining ribs can be heated in the microwave oven for about 10 minutes. It is not recommended to leave it for too long, because the food itself will lose water in the microwave oven and will soon appear dry. Microwave ovens use high frequency heating, which is very fast. Too long will make food dry, harden and even produce toxins. So the time should be adjusted according to the kind of food. ?

High temperature will spill oil, which may lead to open fire and fire. If there is an accidental fire in the furnace, don't open the door immediately. Turn off the power first, and then open the door when the fire goes out.

Ordinary plastic containers are prohibited in microwave ovens. First of all, hot food will deform plastic containers. Second, ordinary plastics will release toxic substances to pollute food and endanger human health. It is forbidden to use metal utensils, because iron, aluminum, stainless steel, enamel and other utensils put into the oven will generate electric sparks when heated in the microwave oven, reflecting microwaves, which will not only damage the furnace body, but also heat food. ?

Avoid using closed containers to heat liquids. Wide-mouth containers should be used, because the heat generated by food heating in a closed container is not easy to dissipate, which makes the pressure in the container too high and easily leads to explosion accidents. Avoid using bottled food with narrow bottleneck, even if the lid is opened, it will expand due to pressure and cause explosion.
