Microwave oven can play a role in sterilization, disinfection.
The microwave oven has a very obvious role in killing bacteria and viruses. It is mainly the use of microwave ovens biological effect that organisms in the microwave oven under the action of the electromagnetic field of the various biological and physiological effects of the impact of the effect, so that the items in the case of lower than room temperature, in a shorter period of time to achieve the purpose of disinfection, sterilization.
Extended information
Microwave disinfection method: put the towel soaked wet into the preservation box, and then microwave oven with a high fire baked 3 to 5 minutes, you can effectively use the high temperature to kill bacteria and microorganisms.
Disinfection effect
Microwave disinfection bacterial spectrum, can kill a variety of microorganisms, as early as in the 40s that is used for wine disinfection, in foreign countries have found that microwave irradiation for 1min can kill a variety of bacterial propagation in the glass ampoule, including fungi, but the huge bacillus bacillus irradiation for 2min, and its killing rate of 99.90%.
According to Kohrer's research proved that the contamination of bacteria, fungi, poliovirus, herpes virus type I dentures, dental trays, dental drills, with 600W microwave irradiation 5min, can be contaminated with microorganisms all killed. Irradiation 8min can kill the spores. Irradiation 3min can be HBsAg antigenic destruction.
Domestic research has proved that the use of a certain type of rapid disinfector, after 5-15min irradiation can be on the metal surface and other objects on the surface of the bacterial spores all killed. At the same time, it is found that Bacillus anthracis-like spores, Bacillus anthracis spores, Bacillus cereus spores, Bacillus thermophilus spores and Bacillus subtilis black variant spores are more resistant to microwave.
It was also reported that the microwave oven with a frequency of 2450±50MHz and an output power of 700W was used for microwave irradiation of test filter paper contaminated with different microorganisms, and the bacterial propagules (Escherichia coli and Staphylococcus aureus) were killed at a rate of 99.87% or more in 1min, and Salmonella typhimurium was killed at a rate of 99.87% or more in 1min.
Microwave irradiation 20min can make Bacillus subtilis black variant spores, thermophilic fat bacillus spores killed, HBsAg irradiation 3min can all destroy its antigenicity.
