Combined tableware disinfection cabinet
- a combination of two or more disinfection methods to sterilize tableware.
According to the disinfection effect
One-star disinfection cabinet
- The killing rate of Escherichia coli Staphylococcus aureus should not be less than 99.9%, and the work requires that the ozone concentration is not less than 20 mg per square meter for 20 minutes.
Two-star disinfection cabinet
- The logarithmic value of killing Escherichia coli Staphylococcus aureus should be ≥3 (≥99.9%)
- Poliovirus infection titer (TCID50) ≥ 105, inactivation logarithm ≥ 4.00, work requires a temperature of 120 degrees for 15 minutes or an ozone concentration of not less than 40 mg per cubic meter for 60 minutes.
Disinfection cabinet size
Built-in disinfection cabinet
Embedded disinfection cabinets can be divided into double doors and three doors.
The difference between these two sizes is relatively large.
Commonly used double-door embedded disinfection cabinets are generally about 600mm in length, 420-450mm in width, and 650mm in height.
Generally, the standard size of the household disinfection cabinet is 80L~100L.
Vertical disinfection cabinet
Mainly does not damage the tableware, can sterilize plastic products, and the internal slide rail can prevent the tableware from being polluted again.
There are vent holes in the front, which effectively prevents water vapor from corroding the cabinets.
The standard size of the vertical disinfection cabinet is 16L enough for the general household population.
Wall-mounted disinfection cabinet
Generally, this kind of disinfection cabinet needs to be determined according to the design of your own home improvement kitchen.
According to the usual summary, the standard size of this type of wall-mounted disinfection cabinet is generally 80L~100L.
The working principle of disinfection cabinet
Principle of UV disinfection cabinet
The sterilization principle of the ultraviolet disinfection cabinet is to irradiate bacteria, viruses, and other microorganisms with ultraviolet rays to damage the structure of DNA in the body, kill bacteria or lose reproduction ability.
DNA absorbs the strongest ultraviolet light with a wavelength of 253.7nm.
The sterilization effect of ultraviolet rays is related to the radiation intensity and total radiation dose, and the killing rate is generally ≥ 99%.
Principle of high-temperature disinfection cabinet
High-temperature sterilization is achieved by heating the temperature to 100 ℃ and keeping it for more than 15 minutes to achieve the purpose of sterilization.
This high-temperature sterilization mainly includes microorganisms such as bacteria and viruses.
High-temperature disinfection cabinets generally use far-infrared heating. 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 microorganisms such as bacteria and viruses on the surface are deformed and killed.
How to use the disinfection cabinet
The tableware should be washed and drained before being disinfected in the disinfection cupboard, which can shorten the disinfection time and reduce the power consumption.
Tableware that is not resistant to high temperatures, such as plastics, cannot be placed in the lower high-temperature disinfection cabinet but should be disinfected in the upper-level ozone disinfection cabinet to avoid damage to the tableware.
Tableware such as bowls, plates, cups, etc. should be placed vertically on the shelf, preferably not stacked, in order to ventilate and disinfect as soon as possible.
Pay attention to whether the ozone generator is working normally. If you can’t hear the squeak of high-voltage discharge or see the blue discharge, it indicates that the ozone generator may be malfunctioning and should be repaired in time.
Please do not open the door when it is not necessary during the disinfection, so as not to affect the disinfection efficiency.
After disinfection, if you take it again after 10 minutes, the effect will be better. A small amount of ozone odor overflows when the cabinet door is opened, and this concentration is not harmful to human health.
How to choose a household disinfection cabinet
Where to use
Users should consider many factors such as the number of households and the types of disinfection utensils when purchasing a disinfection cabinet.
If the population is large, you should buy a large-capacity cabinet.
Function
The disinfection cabinet is equipped with various functions such as disinfection, heat preservation, drying, and door opening alarm.
The disinfection function of the computer cabinet is the best.
Disinfection effect
The main purpose of buying a disinfection cabinet is to disinfect food utensils.
But don’t all disinfection cabinets have a disinfection effect?
In view of the uneven quality of the current disinfection cabinet industry, consumers should pay attention to whether the product has a sanitary inspection report from an authoritative health department when purchasing a product.
Look at energy saving
The length of heating time and the stability of its work are directly related to the consumption of electrical energy.
Generally speaking, the computer disinfection cabinet adopts constant temperature disinfection and completes the disinfection process with the best temperature and the shortest time, which fundamentally solves the problem of power-saving and can greatly reduce the cost of use.
After-sales service
After-sales service is an extension of product quality assurance. When purchasing, we must fully consider whether the manufacturer has complete after-sales service outlets and a good service reputation in the region.
Many small businesses cannot guarantee after-sales service due to resource constraints.
Cleaning and maintenance of disinfection cabinet
Items to be placed in the disinfection cabinet should be kept dry
The electrodes of the infrared heater tube in the disinfection cabinet are easily oxidized due to moisture.
Therefore, if the bowl is dripped with water and placed in the disinfection cabinet for disinfection, the internal electrical components and metal surfaces are easily oxidized by moisture.
Shorten the service life of the disinfection cabinet.
So be careful not to put water-containing tableware, utensils, towels, etc. in the disinfection cabinet for disinfection.
Make sure that the disinfection cabinet is often energized for disinfection.
Although the sealing of the disinfection cupboard is better, if the infrared tube inside does not heat up for a long time, the humid air in the cupboard will not be discharged in time, and the mold attached to the tableware will still breed and endanger human health.
Therefore, even if the disinfection cabinet is not used, it should be energized for disinfection and sterilization to avoid the growth of mold attached to the tableware.
Choose tableware materials
Different types of tableware should be sterilized separately, that is, the tableware that is not resistant to high temperature can be put into the low-temperature disinfection room for disinfection, and the high-temperature resistant tableware can be placed in the high-temperature disinfection room.
When the disinfection cabinet is working, the internal temperature can be as high as 200 degrees Celsius.
Often placing food in these sterilized colorful porcelains can easily contaminate the food and endanger health.
Positioning should be scientific
The disinfection cabinet should be placed in a dry and ventilated place, not less than 30 cm away from the wall.
Please do not open the door when it is not necessary during disinfection, so as not to affect the effect. After disinfection, the effect will be better if it is taken after ten minutes.
For disinfection cabinets, clean and maintain regularly
First of all, the water in the water collection box at the lower end of the disinfection cabinet should be poured out and cleaned.
When cleaning the disinfection cabinet, you must first unplug the power plug and wipe the inner and outer surfaces of the disinfection cabinet with a clean damp cloth, and be careful not to rinse the disinfection cabinet with water.
