Boiling disinfection method >; Boil the cleaned chopsticks in boiling water for 5~ 10 minutes. It should be noted that wooden chopsticks will bend and deform when heated, so this kind of tableware cannot be disinfected in this way.
Steam disinfection method >: put the washed tableware into a steam cabinet or steam box, and disinfect it for about 5 ~ 100 minutes when the temperature rises to100 degrees. Disinfection of dishwasher and disinfection cabinet. Boiling disinfection is the first choice for common disinfection methods above & gt.
In order to achieve the expected effect, high temperature disinfection must meet two conditions at the same time: one is temperature, and the other is time. Generally speaking, boiling water at 100℃ will last for more than 5 minutes before killing or inactivating some bacteria and microorganisms. Most bacteria that often cause acute diarrhea die after 100℃ high temperature 1-3 minutes or 80℃ 10 minutes.
We use hot water to iron dishes and chopsticks, and the water can only wash away some bacteria, but the effect is very limited! Some media have done experiments, taking samples after scalding with 100℃ water. The test results show that the surface bacterial value is 40RLU (relative light unit), while the surface bacterial value before scalding is 46RLU. After scalding tableware with boiling water, the bacterial value drops very little and the effect is very weak. By comparing the experimental results, it is found that it is of little use to pour boiling water on the dishes before meals. > these are just self-consolation!
Some people like to wipe dishes and chopsticks with white wine, thinking that they can be disinfected. Actually, it's not, because the concentration of alcohol used for disinfection in medicine is 75%, and alcohol with too low concentration can't kill bacteria! The alcohol content of general liquor is mostly below 65%. Therefore, wiping tableware with white wine can not achieve the purpose of disinfection at all.
Attention should be paid to boiling disinfection:
Tableware must be thoroughly cleaned first. Disinfected tableware should be completely immersed in water. Articles should not be placed too much >, generally not more than 3/4 of the container. Watertight items, such as bowls and plates, should be placed vertically to promote water convection. When the water boils, start the timer, which usually boils for 5~ 10 minutes; The items of hepatitis patients should be boiled for 30 minutes. Do not add new items during the continuous boiling process. & gt
