We can see the disinfection cabinet in the hotel. Is the household disinfection cabinet suitable? Is the household disinfection cabinet useful? How to use household disinfection cabinet? Let's have a look.
The temperature in the lower high-temperature disinfection cabinet is very high, so plastic products and other catering utensils that are not resistant to high temperature cannot be placed, but should be placed in the upper ozone disinfection low-temperature disinfection cabinet for disinfection, so as not to damage the tableware.

Household disinfectant cabinet
Is the household disinfection cabinet useful? The answer is yes.
Characteristics of different household disinfection cabinets
Household disinfection cabinets often show different characteristics according to different disinfection methods. General household disinfection cabinets are mainly divided into ultraviolet ozone, ozone, infrared high temperature, ultra-high temperature steam, ultraviolet ozone and high temperature. Ozone and ultraviolet ozone belong to ultra-low temperature disinfection. The disinfection temperature is generally below 60 ℃. They are suitable for all kinds of tableware, especially for plastic and glass products that are not resistant to high temperature. Infrared high temperature, over temperature steam, ultraviolet ozone and high temperature belong to thermal disinfection or multiple disinfection methods. The disinfection temperature is generally above 100 ℃ and the disinfection effect is good. It is suitable for the disinfection of high temperature resistant products such as ceramics and stainless steel.
Double door disinfection cabinet is more practical
In the household disinfection cabinet, the more common disinfection cabinet is the double door disinfection cabinet, because the tableware in the family can generally be divided into high-temperature resistant and non high-temperature resistant, and the general double door cabinet has two functions of high-temperature and low-temperature disinfection.
The volume is exquisite
At present, the volume of disinfection cabinet on the market mainly includes 30 liters, 50 liters, 80 liters, 150 liters and other specifications. As a household disinfection cupboard, the power should not be too large, and 600W is a more appropriate value. In terms of volume, for a family of three, 50l-60l disinfection cabinet is generally enough; Families with more than 4 people can choose 60l-80l disinfection cabinet.
Is the disinfection cabinet useful
Disinfection cupboards are household appliances that most families will have, but some people think that disinfection cupboards are useless. In fact, as long as it is a regular product, it is still useful, but the level of disinfection is different.
High temperature disinfection generally adopts the heating temperature greater than 100 ℃ and lasts for more than 15 minutes to denature the protein tissue of microorganisms, including bacteria and viruses, so as to kill bacteria and viruses. The far-infrared method is the heating method of the high-temperature disinfection cabinet, which often adopts steps. The principle is that the electric heating element heats the air or generates radiant heat. After the tableware is continuously affected by high temperature for a period of time, the surface bacteria, viruses and other microorganisms are deformed and killed.
Star disinfection effect:
One star disinfection cabinet requires that the temperature in the disinfection cabinet is above one hundred degrees Celsius, and the duration is more than 15 minutes. It can kill Staphylococcus aureus and Escherichia coli and so on. The killing rate is 99.9%, but it can not kill the hepatitis B virus effectively. So consumers should take this as a very important reference standard when purchasing.
The two star disinfection cabinet requires that the temperature in the disinfection cabinet can reach more than 120 degrees Celsius and last for more than fifteen minutes. Besides killing Escherichia coli, Staphylococcus aureus and other bacteria, it also destroys hepatitis B virus and poliovirus and other viruses. The killing rate is 99.9%. But it has no effect on inorganic chemical poisons and a few special biological viruses. High temperature disinfection is easy to understand and intuitive. I won't introduce it here. Its disadvantage is that the power is too large, which is easy to lead to uneven temperature. High temperature is easy to damage and deform the cavity, seals and heating objects, and it is easy to produce too high temperature for the panel and handle, which has certain potential safety hazards.
UV antivirus:
Ultraviolet is a kind of visible light produced according to the principle of radiology; Blue light does not disinfect. According to the wavelength range, ultraviolet can be divided into three bands: A, B and C and vacuum ultraviolet. A-band 320 ~ 400nm; B-band 275 ~ 320nm; C-band 200 ~ 275nm; Vacuum ultraviolet 100 ~ 200nm; Among them, the real bactericidal effect is C-wave ultraviolet, especially the ultraviolet with the wavelength of 253.7nm. Ultraviolet light can kill all kinds of microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi and so on.
Its sterilization principle is to destroy the structure of DNA (deoxyribonucleic acid) in the body through ultraviolet irradiation of bacteria, viruses and other microorganisms, so as to make them die or lose their reproductive ability immediately. DNA has the strongest absorption of ultraviolet light with a wavelength of 253.7 nm. The germicidal efficacy of ultraviolet radiation is related to its irradiation intensity and total irradiation amount, which can generally reach the killing rate & Ge; 99％。 When the irradiation dose (the product of irradiation intensity and irradiation time) increases, the number of killed bacteria increases, but the percentage of killed bacteria does not increase in proportion to the irradiation dose. A relatively small dose can also kill a few bacteria; If there is a large amount of bacteria, even with a considerable dose of irradiation, some bacteria are still free from death. Its disadvantage is that ultraviolet rays can only propagate along a straight line, with low radiation energy and weak penetration. It can only kill directly irradiated microorganisms. Therefore, during disinfection, the disinfected parts should be fully exposed to ultraviolet rays as far as possible.
Due to the structure of the disinfection cabinet itself and the dense arrangement of bowls and plates, the ultraviolet radiation is blocked by the bowl and plate itself, many parts of the bowl and plate cannot be irradiated by ultraviolet light, and the bacteria and viruses in these parts will not be killed by ultraviolet light. Therefore, the national standard stipulates that the tableware disinfection cabinet cannot only use ultraviolet light as a single disinfection means.
Usually, direct exposure to ultraviolet light is harmful to people. However, the ultraviolet transmittance of ordinary glass and tempered glass is only 0.01-0.1%. Therefore, the use is absolutely safe and reliable. Since ultraviolet radiation is harmful to human body, leakage is absolutely not allowed. If ultraviolet radiation can be directly seen from any opaque part of the machine, it shall be stopped immediately for maintenance.
Usage of disinfection cabinet
The use time and methods of disinfection cupboards of different specifications are different. Before using disinfection cupboards, you should read the operation manual in detail and use them according to the key points in the manual.
Precautions for use of disinfection cabinet:
Many users of disinfection cabinet deviate from the disinfection method in the application of disinfection cabinet. Here are three precautions.
1. Colored porcelain utensils put into the disinfection cabinet will release harmful substances and endanger human health. Because when porcelain ware is glazed, its glaze and pigment contain toxic heavy metals such as lead and cadmium. Although these chemical elements are generally stable in the atmospheric environment, they are easy to release harmful substances in case of high temperature. If it is placed in a high-temperature disinfection cabinet that can reach 200 degrees Celsius, it will be very dangerous.
2. After washing the dishes and chopsticks, they should be drained and then put into the disinfection cabinet, which is more conducive to the disinfection cabinet's killing of bacteria.
3. The temperature in the lower high-temperature disinfection cabinet is very high, so plastic products and other catering utensils that are not resistant to high temperature cannot be placed, but should be placed in the upper ozone disinfection low-temperature disinfection cabinet for disinfection, so as not to damage the tableware. However, Xiaobian suggested not to put the tableware of plastic products into the disinfection cabinet as far as possible, so as not to cause health damage.
