working principle
Microwaves refer to electromagnetic waves between 300 MHz and 300 GHz.
Generally, substances are composed of polar molecules and non-polar molecules. Under the action of the microwave electromagnetic field, the polar molecules in the medium change from the original thermal motion state to follow the alternation of the microwave electromagnetic field and rearrange their orientations. For example, when the microwave frequency is 2450 MHz, there will be 2.45 billion arrangements per second, and there will be intense friction between molecules due to the movement.
The unique heating mechanism of microwave is completely different from the traditional heating method. The traditional heating method is to add the surface of the object first, and then the heat is transferred from the surface to the inside, while the microwave heating is to heat the inside and outside of the object "simultaneously".
Features of microwave heating and drying equipment
1. Rapid heating: The mechanism of microwave heating is different from the traditional heating method. It makes the heated material itself become a heating body, and does not require a heat conduction process, so that the material reaches the heating temperature in an instant.
2. Uniform heating: microwave energy penetrates into the material, so that heat energy is generated inside and outside the material at the same time, the heating uniformity is good, and the phenomenon of external coke endogenous will not occur.
3. Energy saving: Due to its unique heating mechanism, microwave has almost no other losses except a small amount of transmission loss, so the thermal efficiency is high, and compared with traditional electric heating and far-infrared heating, energy saving is more than 1/3-1/2.
4. Synchronization of heating and sterilization: Microwave has thermal and non-thermal biological effects, and can sterilize and remove mildew at a lower temperature. Due to the fast heating speed and short time, the original substances, nutrients and Original color.
5. Easy to control The microwave power can be controlled by PLC man-machine interface to realize immediate heating and termination, and realize the continuous production of the process.
6. The microwave suppressor prevents the leakage of microwave energy, and the microwave energy is heated quickly and quickly, and occupies a very small area. The scientific leakage energy suppression system makes the microwave leakage strictly controlled within the scope of the national standard, no radioactive substances are produced, and no harmful gas emissions, no waste heat, and no dust pollution are generated in the whole process. The thermal effect of microwaves on bacteria means that microwave energy converts heat energy in microorganisms, which increases their temperature, thereby denaturing and solidifying proteins in their bodies, and making bacteria lose nutrients and living conditions.
Microwave sterilization features:
1. The action time is short and the sterilization effect is good. The microwave's unique heat transfer method uses thermal effect and non-thermal biological effect to carry out deep sterilization both inside and outside the material in a short time.
2. The product has good effect. Microwave sterilization maintains the color, aroma, taste and physical and nutritional components of the original material to the greatest extent.
3. Clean and hygienic microwave sterilization will not produce pollution and pollution residues, intelligent control, easy to operate, and the cost is greatly reduced compared with the drill 60.
4. Convenience and quickness Because most of the packages are "transparent to microwave", the packaged materials can be sterilized together with the package, which reduces the labor intensity, and the operation is convenient and fast.
