Microwave cardboard and pulp drying equipment concentrates microwave energy for fast heating without radioactive hazards. The process emits no harmful gases, residual heat, or dust pollution. Additionally, these microwave cardboard drying systems offer anti-mold and sterilization features, providing sterilization during microwave drying to significantly enhance the cardboard's resistance to mold and extend its shelf life. They are energy-efficient, environmentally friendly, safe, hygienic, noiseless, and pollution-free. Easy to control and suitable for automation production.
Operating Principle:
Typically, some medium materials are composed of polar and non-polar molecules. Under the action of microwave electromagnetic fields, polar molecules change from their original thermal motion state to align themselves with the alternating direction of the electromagnetic field. This generates a frictional heat, where the energy of the alternating electromagnetic field is converted into thermal energy within the medium, resulting in a macroscopic increase in temperature — this is a通俗 explanation of microwave heating. It can be seen that microwave heating causes the medium material to dissipate electromagnetic field energy and heat up. For metallic materials, the electromagnetic field cannot penetrate the interior and is reflected instead, so metals cannot absorb microwaves. Water is a microwave-absorbing medium, so substances containing water will definitely absorb microwaves. Some mediums, although composed of non-polar molecules, can also absorb microwaves to varying degrees.
