Microwave sterilization It is the result of the joint action of the thermal effect and biological effect of the electromagnetic field. The thermal effect of microwave on bacteria is to change the protein, so that bacteria lose nutrition, reproduction and survival conditions and die. The biological effect of microwave on bacteria is that the microwave electric field changes the potential distribution of the cell membrane section, affects the concentration of electrons and ions around the cell membrane, thus changing the permeability of the cell membrane. As a result, bacteria are malnourished, unable to metabolize normally, cell structure and function are disordered, and growth and development are inhibited and die. In addition, nucleic acids [RNAs] and deoxyribonucleic acids [DNAs] that can enable normal growth and stable genetic reproduction of bacteria by microwave are relaxed, broken and recombined by several hydrogen bonds, thus inducing genetic gene mutation, or chromosomal aberration or even breakage.

microwave heating

Microwave is a radio wave with a frequency of 300 MHz to 300 GHz. The water molecule in the heated medium material is a polar molecule. Under the action of rapidly changing high-frequency electromagnetic field, its polarity orientation will change with the change of external electric field. This will cause the motion of molecules to show the mutual friction effect. At this time, the field energy of the microwave field will be converted into the heat energy in the medium, so that the temperature of the material will rise, and a series of physicochemical processes such as heating and expansion will be generated to achieve the purpose of microwave heating and drying.

Microwave heating is the process of heating objects by using the energy characteristics of microwave. Microwave has obvious characteristics such as wave length (1m~1mm), high frequency (300MHZ~300GHZ) and quantum properties. Microwave technology is widely used in radar, navigation, multi-channel communication, remote sensing and television. Since the 1960s, people have gradually Microwave heating technology It is used in physical processing such as paper, wood and resin extrusion. In recent years, the introduction of microwave heating technology into the production process of microwave molybdenum industry can not only effectively improve the conversion rate and selectivity of reaction, but also reflect many advantages such as energy conservation and environmental protection. As one of the means to achieve green technology, it has attracted widespread attention.
