1, bread can be put in the microwave heating. Bread can be put into the microwave heating, but the heating time can not be too long, otherwise the water in the bread will be lost leading to bread hardening. Bread heating method: heating with high heat, heating about 13 seconds. Or heat on medium heat for about 23 seconds. When heating work, the microwave oven heating endothermic object drag plate will rotate itself, to ensure that the heated object meets the heat evenly.

2, the working principle of the microwave oven: microwave oven magnetron will be converted into microwave energy, when the magnetron to 2450MHZ frequency emitted microwave energy, placed in the microwave oven cavity of the water molecules in order to change the frequency of 24. 5 billion times per second for oscillation operation, the core components of the electromagnetic field to produce high-frequency magnetron. Food molecules in the high-frequency magnetic field vibration, the molecules collide with each other, friction and generate heat energy, the result is that the food is heated.
