The working principle of the disinfection cabinet is basically known as the disinfection cabinet.

For our health and other issues, we use a disinfection cabinet to disinfect the tableware we use every day. There are a lot of people who have great doubts about the disinfection effect of the disinfection cabinet. So, in the end, can the disinfection cabinet really be disinfected? Then we should start from the two aspects of the working principle and basic knowledge of the disinfection cabinet.

What is the working principle of the disinfection cabinet?

1. Principle of UV disinfection cabinet

The sterilization principle of the ultraviolet disinfection cabinet is to irradiate microorganisms such as bacteria and viruses through ultraviolet rays to damage the structure of DNA in the body, kill bacteria or lose reproductive ability. DNA absorbs most ultraviolet light at a wavelength of 253.7 nm. The sterilization effect of ultraviolet light is related to its irradiation intensity and total irradiation amount, and generally can reach a killing rate of ≥ 99%.

2. Principle of high temperature disinfection cabinet

High-temperature disinfection is achieved by heating the temperature to 100 °C for more than 15 minutes. This high-temperature sterilization mainly includes microbial organisms such as bacteria and viruses. The high-temperature disinfection cabinet generally adopts the far-infrared heating method. The electric heating element heats the air or generates radiant heat. After the appliance is subjected to high temperature for a period of time, the surface of the microbial organisms such as bacteria and viruses are deformed and thus killed.

Classification of high temperature disinfection cabinets

The high temperature disinfection cabinet is generally divided into a one-star disinfection cabinet and a two-star disinfection cabinet. The basis of the distinction is different from their bactericidal effect. Generally, the one-star sterilizer requires the temperature in the sterilizer to reach 100 °C or above, which can kill bacteria such as Escherichia coli and Staphylococcus aureus, and the killing rate is 99.9 %. But not to kill hepatitis B virus;

The two-star disinfection cabinet requires the temperature inside the disinfection cabinet to reach 120 °C or above. In addition to killing the bacteria that can be killed by the one-star disinfection cabinet, it can also kill viruses such as hepatitis B virus and poliovirus, and the killing rate is 99.9 %. . But it does not work for inorganic chemical poisons and a few special biological viruses.

Disinfection cabinet basics

Look at the application

When purchasing a disinfection cabinet, you should consider the number of family members, the size of the living room, the place of use, the type of disinfection utensils, etc., etc.: Generally, a three-door house or an ordinary office and a reception room use single or double door disinfection with a volume of less than 100 liters. Cabinets, if the population is large, the corresponding volume rise can be larger. If the room size is small, it is more suitable to choose 60 liters or less, otherwise 70-100 liters may be selected. The disinfection cabinets of 150 liters to 400 liters are mainly used for disinfection of utensils in public places such as hotels and canteens.

There are two main types of disinfection cabinets in the market: low temperature disinfection and high temperature disinfection. High temperature disinfection can only be applied to high temperature resistant utensils, such as ceramics and stainless steel. If you want to disinfect plastics and other high-temperature utensils, you can use a double-door disinfection cabinet that combines ozone and high-temperature disinfection.

Look function

The disinfection cabinet has various functions such as disinfection, heat preservation, drying, and door opening alarm. General consumers can purchase a single disinfection function disinfection cabinet. To suit different types of utensils, consider purchasing ozone and high-temperature disinfection double door cabinets. Other functions can be selected according to different needs. The heat preservation function mainly keeps the food utensils with a certain temperature, and the hand feel is comfortable when using the food utensils, and is especially suitable for the vast northern regions.

See sterilization effect

The main purpose of consumers to buy disinfection cabinets is to sterilize, store and clean the utensils. Therefore, the indicator of sterilization and disinfection is very important. Different disinfection temperature, ultraviolet intensity, ozone concentration, disinfection time and other factors will directly affect Sterilization effect, consumers should pay attention to whether the product has the health inspection report of the authoritative health department and the quality inspection report of the quality inspection department.

Look at energy efficiency

Disinfection cabinets of the same volume and power, in order to achieve the purpose of high temperature sterilization, the structure, materials and processes used will affect the thermal insulation effect of the disinfection cabinet, thus affecting the length of heating time, which is directly related to the consumption of electric energy.

Look after service

Good after-sales service is an extension of product quality assurance. When purchasing, we must fully consider whether the manufacturer has perfect after-sales service network and good service image in the region.

Regarding the working principle and basic knowledge of the disinfection cabinet, I believe that we should all know what we have learned through our introduction. The role of the disinfection cabinet can not be ignored. For the sake of family health, remember to have regular disinfection work.
