The working principle and characteristics of microwave drying sterilizer

The principle of the microwave drying sterilizer is the result of the combined effect of the thermal and biological effects of the electromagnetic field. The thermal effect of microwave on bacteria is to change the protein, so that the bacteria lose their 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, which affects the concentration of electrons and ions around the cell membrane, thereby changing the permeability of the cell membrane. Therefore, the bacteria are malnourished, unable to metabolize normally, cell structure and function disorder, and growth and development are prevented. And death.

Features of microwave drying and sterilization machine, saving energy: Conventional thermal sterilization often has heat loss in the environment and equipment, while microwave directly processes food, so there is no additional heat loss. In comparison, it can generally save 30-50% of electricity. Conventional thermal sterilization starts from the surface of the material and then transfers to the inside through heat conduction. There is a temperature difference between inside and outside. In order to maintain the food flavor and shorten the processing time, often the inside of the food does not reach a sufficient temperature, which affects the sterilization effect.

1. Easy to control: microwave food sterilization, the equipment can be used immediately, without the thermal inertia of conventional thermal sterilization, flexible and convenient operation, the microwave power can be continuously adjusted from zero to the rated power, and the transmission speed can be continuously adjusted from zero, which is convenient control.

2. Simple equipment and advanced technology: Compared with conventional disinfection and sterilization, microwave sterilization equipment does not require boilers, complicated piping systems, coal yards and transportation vehicles, as long as it has basic water and electricity conditions.
