Q：The difference between steam disinfection and ultraviolet disinfection

A：
Disinfection can be said to be a common way to kill bacteria and viruses in our daily lives. In fact, disinfection is indispensable not only in our personal households, but also in the food processing industry, medical industry, precision machinery and other industries. An important link. Sterilization and disinfection may seem very simple on the surface, and there may not even seem to be much difference between those that have been sterilized and those that have not been sterilized, but in fact it is related to the safety of the product, the health of the human body, etc. There are currently two most commonly used and widely used sterilization methods on the market, one is high-temperature steam sterilization and the other is ultraviolet disinfection. At this time, some people will ask, which of these two sterilization methods is better? ?

Steam sterilization: It mainly uses the high-temperature steam produced by the steam generator to sterilize the areas that can be covered. The principle of steam sterilization is mainly to use high-temperature steam to perform high-temperature sterilization. Under normal circumstances, it only takes about ten minutes to complete. Large area anti-virus.

Ultraviolet disinfection: Ultraviolet disinfection mainly uses ultraviolet wavelengths to destroy bacteria on the surface of items. Disinfection can be completed after a period of time, but the disinfection area is small and needs to be exposed to ultraviolet rays before it can be sterilized and disinfected.

So what are the differences between the two?

1. Different methods of sterilization: Steam generators mainly use the high-temperature steam generated to sterilize items. Ultraviolet rays mainly use ultraviolet rays to sterilize and disinfect.
2. The scope of disinfection is different: the scope of sterilization and disinfection of steam generators is relatively wide. Ultraviolet disinfection can only disinfect the places where it can be irradiated, and other places cannot be disinfected.
3. Different environmental protection properties: The high-temperature steam generated by the steam generator is very clean, and has strong permeability and thermal conductivity. During this period, no radiation will be produced, which is safe and environmentally friendly. Ultraviolet rays are different. Ultraviolet rays have a certain amount of radiation.

4. Disinfection speeds are different: When the steam generator is turned on, you may have to wait 1 to 2 minutes, while the ultraviolet machine can be disinfected immediately when it is turned on.
5. Different pressures are required: When the steam generator is in use, it needs to reach a certain pressure before it can be used for sterilization and disinfection. Ultraviolet light is not needed and can be used immediately after turning on the machine.
6. The places where they are placed are different: the size of the place depends on the size of the place. Steam generators are generally relatively fixed machines with similar sizes, and the required places are relatively stable. Moreover, a small steam generator can produce a large amount of steam and needs to be placed Fixed place. Ultraviolet light depends on the size of the machine and the area that needs to be disinfected.

Generally speaking, ultraviolet light is usually used at home. It is small and convenient, and can be moved at will. However, it is more difficult to use it in factories because factories require large For disinfection and sterilization in batches, it is difficult for ordinary ultraviolet machines to meet the needs of the factory.
