Household disinfection cabinet

Is the home disinfection cabinet useful? The answer is yes.

The characteristics of different household disinfection cabinets

Household disinfection cabinets often exhibit 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℃. It is suitable for all kinds of tableware, especially for plastic and glass products that are not resistant to high temperatures. Infrared high temperature, ultra-temperature steam, ultraviolet ozone and high temperature are heat 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.

Two-door disinfection cabinet is more practical

The more common disinfection cabinets in household disinfection cabinets are mainly double-door disinfection cabinets, because the tableware in the family can generally be divided into two types, high temperature resistant and non-high temperature resistant, and general two-door cabinets have both high temperature and low temperature disinfection functions. .

Pay attention to the size

At present, the volume of disinfection cabinets on the market mainly has specifications such as 30 liters, 50 liters, 80 liters, and 150 liters. As a daily household disinfection cupboard, the power should not be too large, 600W is a more appropriate value. In terms of volume, for a family of three, a 50L-60L disinfection cabinet is generally sufficient; a family with more than 4 people can choose a 60L-80L disinfection cabinet.

Disinfecting cupboards are household appliances that most households have, but some people think that disinfecting cupboards is 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 heating temperature greater than 100°C and lasts for more than 15 minutes to denature the protein tissue of microorganisms including bacteria and viruses to achieve the purpose of killing bacteria and viruses. The far-infrared method is the heating method of the high-temperature disinfection cabinet. The principle is that the electric heating element heats the air or generates radiant heat. After the food utensils are subjected to high temperature for a period of time, the surface of the bacteria, viruses and other microbial protein tissues are deformed, thereby Be killed.

Star disinfection effect:

The one-star disinfection cabinet requires that the temperature in the disinfection cabinet be more than 100 degrees Celsius and the duration should be more than 15 minutes. It can kill bacteria such as Staphylococcus aureus and Escherichia coli. The killing rate is 99.9%, but it cannot be effectively killed. Hepatitis B virus, 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 be above 120℃ and last for more than 15 minutes. In addition to killing bacteria such as Escherichia coli and Staphylococcus aureus, it can also kill hepatitis B virus and polio virus. The virus has a killing rate of 99.9%. But it does not work on inorganic chemical poisons and a few special biological viruses. High temperature disinfection is easier to understand and intuitive, so I won’t introduce it here. The disadvantage is that the power is too large, which can easily lead to uneven temperature. High temperature can easily damage and deform the cavity, seals and heating objects, and easily cause excessively high temperatures in the panel and handle, which poses certain safety risks.

UV antivirus:

Ultraviolet light is a short wave with a wavelength outside the visible range. It is a kind of visible light generated according to the principle of radiation; blue light does not have a disinfection effect. According to the wavelength range, ultraviolet rays can be divided into three bands: A, B, and C and vacuum ultraviolet rays. A wave band is 320～400nm; B wave band is 275～320nm; C wave band is 200～275nm; vacuum ultraviolet is 100～200nm; among them, C wave ultraviolet light has the real bactericidal effect, especially the ultraviolet light with wavelength of 253.7nm. Ultraviolet rays can kill various microorganisms, including bacterial propagules, spores, mycobacteria, viruses, fungi, etc., with a broad spectrum.

The principle of sterilization is to use ultraviolet rays to irradiate bacteria, viruses and other microorganisms to destroy the structure of DNA (deoxyribonucleic acid) in the body, causing it to immediately die or lose its ability to reproduce. DNA absorbs the strongest ultraviolet light with a wavelength of 253.7nm. The bactericidal effect of ultraviolet rays is related to the radiation intensity and the total radiation dose, and the killing rate is generally ≥99%. When the radiation dose (the product of the radiation intensity and the radiation time) increases, the number of bacteria killed increases, but the percentage of bacteria killed does not increase in proportion to the radiation dose. A relatively small dose can also kill a small number of bacteria; if the amount of bacteria is large, even a relatively large dose of radiation still has some bacteria to avoid death. The disadvantage is that the ultraviolet rays can only travel in a straight line, the radiation energy is low, and the penetrating power is weak. It can only kill the directly irradiated microorganisms. Therefore, the disinfected parts should be fully exposed to ultraviolet rays when disinfecting.

Due to the structure of the disinfection cabinet and the dense arrangement of the dishes, the ultraviolet radiation is blocked by the dishes themselves, and many parts of the dishes cannot be irradiated by ultraviolet light. The bacteria and viruses in these parts will not be killed by ultraviolet light. , The national standard stipulates that the disinfection cabinet for food utensils cannot only use ultraviolet rays as a single disinfection method.

Usually, direct exposure to ultraviolet rays is harmful to people. But the ultraviolet light transmittance of ordinary glass and tempered glass is only 0.01-0.1%. Therefore, the use is absolutely safe and reliable. Because ultraviolet radiation is harmful to the human body, leakage is absolutely not allowed. If ultraviolet rays can be seen directly from any opaque part of the machine, stop using it and inspect it immediately.

How to use the disinfection cabinet

Different specifications of disinfection cupboards have different lengths and methods of use. Before using the disinfection cupboards, you should read the instructions in detail and use them according to the main points in the instructions.

Precautions for the use of disinfection cabinet:

Many users of the disinfection cabinet have deviated from the disinfection method in the use of the disinfection cabinet. Here are three precautions.

1. Putting colored porcelain utensils into the disinfection cabinet will release harmful substances and endanger human health. This is because the enamel and pigment of porcelain utensils contain toxic lead, cadmium and other heavy metals when they are glazed. Although under normal circumstances, these chemical elements are relatively stable in the atmospheric environment, they are likely to release harmful substances when encountering high temperatures. 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 put in the disinfection cabinet, which is more conducive to the sterilization of bacteria by the disinfection cabinet.

3. The temperature in the lower high-temperature disinfection cabinet is very high, so plastic products and other tableware that are not resistant to high temperatures cannot be placed, but should be disinfected in the upper-level ozone disinfection cabinet to avoid damage to the tableware. However, the editor recommends not to put plastic tableware into the disinfection cabinet as much as possible, so as to avoid health damage.
