WeiyasPrinciple of microwave heating equipment: Most dielectric materials are composed of polar and non-polar molecules. Under the action of microwave electromagnetic field, polar molecules change from their original thermal motion state to align and orient according to the direction of the electromagnetic field. In this microscopic process, the energy of the alternating electromagnetic field is converted into thermal energy inside the medium, causing the temperature of the medium to rise. This is a popular explanation for microwave heating. From this, it can be seen that microwave heating is caused by the loss of electromagnetic field energy by the dielectric material itself, resulting in heat generation. The electromagnetic field of metal materials cannot penetrate into the interior and be reflected, and metal materials cannot absorb microwaves. Special measures need to be taken for microwave heating of metals. Water is a good medium for absorbing microwaves, so any substance containing water must absorb microwaves. Although some media are composed of non-polar molecules, they can also absorb microwaves to varying degrees. The principle is that microwave heating belongs to the overall heating method, and electromagnetic energy directly acts on the media molecules to convert them into heat. The transmission performance allows the media to be heated both inside and outside, without the need for thermal conduction. However, the lack of heat dissipation conditions inside causes the internal temperature to be higher than the external temperature gradient distribution, resulting in a migration and evaporation rate of water. Especially for products with a moisture content of less than 30%, the evaporation time of water can be shortened by a hundred times, achieving uniform drying in a short period of time.
microwavableUnlike conventional heating methods, conventional heating methods such as flame, hot air, electric heating, steam, etc. all use the principle of heat conduction to transfer heat from the outside of the heated object to the inside, gradually increasing the temperature at the center of the object, which is called external heating. It takes some time to reach the desired temperature at the center, and objects with poor thermal conductivity require even longer time. Microwave heating is an internal heating method that turns the object itself into a heating element, without the need for thermal conduction. It heats both the inside and outside simultaneously, thus achieving heating effect in a short period of time.
