Magnetrons play a crucial role in microwave equipment such as ovens, with their core function being to convert direct current into microwaves, thereby achieving heating and other effects. After being generated by a magnetron, microwaves have the following main functions:
1、 Heating effect
Efficient heating: Microwaves can penetrate the surface of food and directly heat the water molecules inside the food, making the food evenly heated from inside to outside, with fast heating speed and high efficiency.
Preserving nutrients: Compared with traditional heating methods, microwave heating can reach the desired temperature in a shorter period of time, which helps reduce the loss of nutrients in food.
2、 Thawing effect
Quick Thawing: Microwaves can quickly penetrate food, causing ice crystals in the food to melt rapidly, thus achieving quick thawing. For example, frozen food can be thawed in just a few minutes in a microwave oven.
3、 Drying and restoring brittleness
Drying food: By controlling the power and time of the microwave, food can be dried, such as placing excessive seasonal vegetables in the microwave oven for baking and storage.
Restoration of brittleness: Some biscuits, melon seeds, and other foods that have become soft due to moisture can be restored to their original crispy texture by heating them in the microwave.
4、 Disinfection function
Sterilization and disinfection: Microwaves can destroy the cellular structure of bacteria, viruses, and other microorganisms, thereby achieving the effect of sterilization and disinfection. For example, heating towels or cloths in the microwave for 30 seconds can have a sterilizing effect.
5、 Other applications
Promoting chemical reactions: Under the action of microwaves, the rate of some chemical reactions can be significantly increased, which has a wide range of applications in chemical synthesis, material preparation, and other fields.
Microwave therapy: By utilizing the thermal and non thermal effects of microwaves, the human body can be treated to promote blood circulation, relieve pain, and more.



In summary, the microwave generated by magnetron plays a wide and important role in heating, thawing, drying, restoring brittleness, disinfection, and promoting chemical reactions. Meanwhile, with the continuous development of microwave technology, the application fields of microwave are also constantly expanding and deepening.
