& gt& gt& gt link: recommended by several major brands of disinfection cabinets.
The capacity of disinfection cabinets varies. At present, there are mainly 30 liters, 50 liters, 80 liters, 100 liters, 150 liters, 250 liters, 350 liters and 700 liters on the market. The inner container of disinfection cabinet is made of galvanized sheet, aluminum sheet, ordinary stainless steel and pure stainless steel, and the price is gradually rising. Generally speaking, the daily disinfection cabinet is below 100 liter, and the inner container is made of ordinary stainless steel, which can meet the needs, but it must be selected according to the number of families and the kitchen area.
Single-door disinfection cabinets generally have only one disinfection method, such as ozone disinfection or ultraviolet disinfection. Two-door disinfection cabinets generally have two or more disinfection methods. Generally, the upper layer is ozone disinfection, which is used to disinfect tableware that is not resistant to high temperature; The lower layer is high-temperature disinfection, which is used to disinfect high-temperature tableware. If you choose a household as a unit, it is best to choose a disinfection cabinet with a variety of disinfection methods, because tableware in the family can generally be divided into two categories: high temperature resistance and low temperature resistance. During disinfection, different disinfection methods can be selected according to whether the object to be disinfected can withstand high temperature.
At present, there are many additional functions in the disinfection cabinet on the market, such as drying and heat preservation, moisturizing, VFD large screen display, hot air internal circulation, microcomputer control, timing switch, adding exhaust holes, special insect net, automatic deodorization and so on. This has also become an important factor affecting prices. The more additional functions, the higher the price.
& gt& gt& gt Link: Recognize three misunderstandings in the purchase of disinfection cabinets.
How to buy a disinfection cabinet must first master four essentials!
1, determine the brand.
Miscellaneous brand disinfection cabinets generally have poor quality, short service life and substandard functions, and are prone to problems such as ozone leakage and high radiation intensity. It is best not to buy such products. Although the disinfection cabinet looks small, its manufacturing process is very demanding. It's best to choose the goods of famous brands, the quality will pass, and the after-sales will be guaranteed.

2. Understand the style
There are many styles such as vertical, horizontal, wall-mounted, embedded, floor-mounted, desktop, open door, drawer and so on. Generally, floor-standing products are suitable for families with large space, large population and many tableware. Wall hanging products are suitable for families with small space, small population and few tableware. Because these two styles exist independently, occupy external space, and it is difficult to unify the styles, which hinders the beauty of the kitchen, so there are not many families in use now. Embedded disinfection cabinet can be integrated with cabinets, often placed under the cooker, especially loved by decorated families.
Step 3 choose the appearance
The appearance of the disinfection cabinet mainly depends on the material, shape and operation panel, mainly according to the user's home decoration style and personal preferences.
Materials can echo other furniture products in style, generally including aluminum alloy, tempered glass, stainless steel, mirrors, etc. In the choice of styling, it is recommended that you do not choose products with prominent handles. The protruding handle is easy to hurt the knee when cooking, and it is also easy to hurt the child.
4. Contrast performance
It mainly depends on the index grade of disinfection cabinet and the application of internal materials.
There are generally three disinfection methods: high temperature disinfection, ozone disinfection and ultraviolet disinfection. Their characteristics are different. All products on the market have separate disinfection methods, but more often, several disinfection methods are used in combination. Choosing a good disinfection method is the most concerned point when people buy products. Let's take a look at their advantages and disadvantages!
Sterilize sth at high temperature
Advantages: the disinfection of electric heating elements can reach 120℃, with thorough disinfection and intuitive disinfection method.
Disadvantages: it is easy to cause uneven temperature, and this disinfection method is not suitable for utensils that are not resistant to high temperature, such as bottles, toys, plastic tableware and so on.
Ozone disinfection
Advantages: the strong oxidation of ozone is used for disinfection, which can be carried out at normal temperature and can be used for disinfection of various utensils. Suitable for large-scale disinfection.
Disadvantages: the sterilization effect is limited, which can not effectively kill hepatitis B virus. Too high a concentration may have an impact on human body.
disinfection by ultraviolet light
Advantages: ultraviolet photochemical conversion disinfection, killing microorganisms is particularly prominent. Can kill the virus in a short time.
Disadvantages: the disinfection penetration is poor, and only the surface of the article can be disinfected, and it can only spread in a straight line, and it is impossible to disinfect the area that cannot be irradiated.
Combined disinfection
Advantages: it can cooperate with different disinfection methods, effectively eliminate different germs, and has good disinfection effect. Different brands and models will have different combinations.
Disadvantages: the price of the product is high, and it is difficult for people who don't know the product to operate it correctly.
Set the purchase target and pay attention to the following points when choosing products:
1. The appearance should be smooth, without cracks and bulges.
2. Electric heating pipes, ozone generators and other parts in the machine body should be installed firmly, with flexible cabinet door switch and reliable control key contact.
3. Turn on the power supply according to the trial instructions.
4. Accessories such as product certificate and instruction manual should be complete, and there should be no gaps.
Working principle of sterilization and disinfection
High temperature type:
As mentioned above, the high-temperature disinfection cabinet uses far infrared rays as a heat source to generate high temperature for disinfection. Far infrared ray is a kind of magnetic wave, which spreads outward by radiation, and has good thermal effect, reaching a high temperature of about 125 degrees, and is particularly easy to be absorbed by various organisms such as bacteria. When the heat energy absorbed by bacteria exceeds its tolerance limit, it will naturally be "heated" alive.
Low temperature type:
Ozone is a light blue gas, which can not only deodorize, keep fresh and freshen the air, but also enter bacteria to destroy their cell structure and oxidase, thus achieving the sterilization effect. Generally speaking, the greater the ozone concentration in the disinfection cabinet and the higher the relative temperature, the better the sterilization effect. However, when the ozone concentration is too high, it will make people's respiratory tract uncomfortable, so it needs to be controlled within a safe limit. In addition, ozone has good reducibility and can be automatically reduced to oxygen within 20 minutes after it is produced, so it will not cause harm to human body. Generally speaking, the working temperature of the low-temperature disinfection cabinet is lower than 80 degrees, which can be used to disinfect utensils made of paint, wood, plastic, knitwear and other materials.
The quality of disinfection cabinet should pay attention to the following performance:
Disinfection effect
That is, the sterilization rate of the disinfection cabinet. The disinfection cabinet will use stars to represent different sterilization degrees. Generally, the higher the star rating, the better the sterilization effect. Two-star products can effectively kill some bacteria that can't be killed by one-star products, and they are products with good sales in the market at present.
Inner container, bowl rack and guide rail
It is best to use all stainless steel materials, which will be stronger, more durable, more corrosion-resistant, less prone to rust and non-toxic than galvanized and aluminum alloy plates. Among them, the liner is best formed at one time, and the seamless liner can avoid ozone leakage and protect family health; There are many different designs of bowl racks, some are suitable for putting bowls and plates, some are suitable for putting spoons and chopsticks, and they are also chosen according to their own habits; There are two kinds of guide rails: internal guide rails and external guide rails. Relatively speaking, the external guide rail can avoid secondary pollution.
roll
Because of the different places of use, the volume of disinfection cabinet products varies from 30 to 700 L. For ordinary families, it is enough to choose products of about 80- 100 L according to the population and the number of articles. The sizes of embedded disinfection cabinets are mostly uniform, and the volume changes will not be much different.
fluorescent lamp
When the disinfection cabinet works, the quality of the internal lamps is also good. It is difficult for ordinary lamps to work normally inside. Generally, high boron lamps and timely lamps are selected. The service life of high boron pipe is about 2000 hours, and the service life of timely pipe is about 5000 hours. Therefore, the products using timely tubes will be more expensive than those using high boron tubes.
Switch tightness
In order to prevent ozone and ultraviolet rays from leaking when the disinfection cabinet works and endanger the health of users, the products should use interlocking switches and check their sealing effect. The Safety and Hygienic Requirements for Tableware Disinfection Cabinet states that the ozone leakage of disinfection cabinet shall not be greater than 0.2mg/m3, so this standard is the best product when purchasing.
Other special functions
In order to enhance the competitiveness of products, disinfection cabinets of well-known brands often have innovative functions. Such as child locks, timing, etc. But the price is more expensive, so you should choose according to the family budget.

■ 4 points for attention when using intimate tips
1. When using the disinfection cabinet, the tableware should be washed and drained before being put into the disinfection cabinet for disinfection, which can shorten the disinfection time and reduce power consumption.
2. Tableware that cannot withstand high temperature, such as plastic, should be disinfected in the upper ozone disinfection low-temperature disinfection cabinet, not in the lower high-temperature disinfection cabinet, so as not to damage the tableware.
3, ozone disinfection, it is forbidden to open the cupboard door, in order to avoid ozone leakage. You can't hear the squeak of high-voltage discharge, and you can't see the blue light of discharge, which indicates that the ozone generator may be faulty and should be repaired in time.
4, bowls, plates, cups and other tableware should be placed vertically on the shelf, it is best not to overlap, so as to ventilate and disinfect as soon as possible.
