This ultraviolet sterilizer is mainly used for sterilizing various foods and packaging products and can be widely used in hospitals, food processing industries, tea and beverage processing, and packaging plants. The UV food sterilizer machine sterilizes all kinds of food according to the ultraviolet irradiation sterilization method, and can effectively kill various microorganisms (such as Escherichia coli and mycete) and bacteria therein, and can greatly reduce the bacteria in the food, thereby serving as food sterilization.
What is the UV sterilizer?
This high-efficiency food sterilizer uses high-frequency C-band ultraviolet rays to destroy DNA of various microorganisms in foods in 20 seconds to 1 minute, and can kill 99% of bacteria and viruses, including: influenza, hepatitis virus, salmonella, Escherichia coli, Staphylococcus aureus, Bacillus subtilis var, spores and various mildew sources, allergens, etc. The ultraviolet sterilizer machine is particularly suitable for rapid sterilization of foods, medicines, cosmetics, tableware, personal and public goods, and other articles.
Main structure of the food sterilization equipment
The main structure of the UV food sterilizer machine includes a main body portion and an electronic control portion. The main body part of the sterilization machine is mainly composed of a sterilization device(full of sterilization lights), a protection device, a body bracket, a conveyor belt, and an exhaust fan.
The inside and outside of the food sterilizer are made of 304 stainless steel. The inside and outside of the main body are polished to enhance the ultraviolet irradiance, ensuring that the disinfectant does not have incomplete sterilization during the sterilization process.
The protection device in this sterilizer is a special design for the safe operation, which mainly includes the three functions: 1. Overvoltage and overcurrent protection. 2. Fault alert prompt. 3. Equipment overload protection.
Working principle of the ultraviolet sterilizer machine
When the ultraviolet rays inside the machine are irradiated to microorganisms and bacteria, energy transfer and accumulation occur, and the accumulation results in the inactivation of microorganisms or bacteria, thereby achieving the purpose of disinfection.
When bacteria and viruses absorb ultraviolet rays in the dose of more than 3600~65000uW/cm2, they have strong destructive power to bacteria, viruses, DNA and RNA, which can make bacteria and viruses lose their viability and reproduction. On the one hand, ultraviolet light can mutate nucleic acids, hinder their replication, transcriptional blockade, and protein synthesis; on the other hand, the generation of free radicals can cause photoionization, leading to bacterial cell death.
What should be noticed when using UV food sterilizer machine?
- UV sterilizers are strictly prohibited from starting frequently, especially in a short period of time. Only in this way can the life of the UV lamp be ensured.
- The ultraviolet sterilizer should be cleaned regularly: UV lamp and quartz glass casing need to be cleaned regularly. When cleaning, wipe the lamp tube with alcohol cotton ball or gauze, remove the dirt on the quartz glass sleeve and wipe it off, so as not to affect the transmittance of ultraviolet light, and affect the sterilization effect.
- When replacing the lamp, first unplug the lamp power socket, then pull out the lamp tube, then carefully insert the cleaned new lamp into the sterilizer, install the sealing ring, check for water leakage, and then insert On the power supply. Be careful not to touch the quartz glass of the new lamp with your fingers, otherwise, the bactericidal effect will be affected by the stain.
- Prevent ultraviolet radiation. Ultraviolet rays have a strong lethal effect on bacteria, and they also have certain damage to the human body. Therefore, when starting the disinfection lamp, avoid direct exposure to the human body. If necessary, use protective glasses. Do not directly look at the light source with your eyes to avoid burning the eye mask.
Main advantages of the UV sterilization machine
- The sterilizer machine has a simple structure, simple operation, and convenient maintenance, small space occupation, and large processing capacity.
- The machine is effective in degrading chlorides in water by photolysis. Therefore, the entire sterilization process is non-polluting and environmentally friendly.
- This sterilizing machine uses the optical principle to design a unique inner wall treatment process, which enables the cavity to maximize the use of ultraviolet rays so that the bactericidal effect is doubled, and various bacteria, viruses, and other microorganisms can be quickly and effectively killed.
