Product details
Ceramic embryo microwave drying equipmentPrinciple:
Conventional heating methods such as flame, hot air, electric heating, steam drying, etc. all utilize the principle of heat conduction to transfer heat from the outside to the inside of the object being heated, gradually increasing the temperature at the center of the object, which is called external heating. It takes some time to reach the desired temperature in the central area, and objects with poor thermal conductivity require even longer time. These traditional drying methods have long drying times, high power consumption, uneven heating, flipping up and down, and high labor intensity. In contrast, microwave drying has the characteristic of penetrating the inside and outside of an object while heating at a frequency of 2450MHz with 2.45 billion oscillations per second,Microwaves are electromagnetic waves with a frequency of 300 megahertz, and the water molecules in the heated medium material are polar molecules. Under the rapidly changing high-frequency electromagnetic field, its polarity orientation will change with the variation of the external electric field, causing molecular motion and mutual friction effects. At this point, the field energy of the microwave field is converted into thermal energy inside the medium, causing the temperature of the material to rise, resulting in a series of physical and chemical processes such as thermalization and puffing, thus achieving the purpose of microwave heating and drying.
