The Ultraviolet food sterilization machine is a new type of sterilizing machine that uses ultraviolet rays to cause fatal damage to a variety of bacteria, and the sterilization rate can reach 100%. In addition, due to its characteristics of not adding any chemical substances in the sterilization process, this sterilization method is also favored by the food processing industry, the water treatment industry, and the pharmaceutical industry.
Introduction of the ultraviolet food sterilization machine
The main body of the UV sterilizer is made of 304 or 316 stainless steel. The internal polishing of the main body is used to enhance the irradiance of ultraviolet rays, to ensure that no incomplete disinfection and sterilization will occur during the process.
At present, people use the principle of ultraviolet sterilization to introduce the hospital’s professional sterilization technology into daily life.
Indoor, home, car, refrigerator, and industrial sterilizers use high-frequency C-band ultraviolet radiation to destroy the DNA of various microorganisms in 20 seconds to 1 minute, killing 99% of bacteria and viruses, including influenza, hepatitis virus, salmonella, Escherichia coli, Staphylococcus aureus, Bacillus subtilis black, color mutant spores and a variety of fungi and allergens.
Providing people with a safe living environment. Therefore, they are especially suitable for quick sterilization and disinfection of food, medicine, cosmetics, tableware, personal and public goods, and other articles.
Application of the ultraviolet food sterilization machine
The ultraviolet food sterilization machine (UV sterilizer) has the advantages of high stability of irradiation intensity and up to 9000 hours of sterilization life. UV radiation belongs to low-energy electromagnetic radiation. Its wavelength is relatively short and its penetration ability is relatively weak. Therefore, except for special quartz glass which can penetrate 80%, most substances cannot or can only penetrate a small amount of ultraviolet radiation.
This UV sterilizer machine is equipped with a quartz glass tube with high transmittance. And the transmittance is more than 87%. what’s more, the unit price is moderate than that of similar products. After a sterilizing life of 8000 hours, the irradiation intensity is stable at 253.7um, which is more stable than the domestic similar products. In addition, there is a sound and light alarm warning when the lamp is broken.
The inner tunnel of the fuselage working area is designed with a high-brightness mirror sterilization reaction chamber. Compared with similar products abroad, the bactericidal strength is increased by 18%-27%, and the bactericidal rate can reach 98.99%.
Ultraviolet food sterilizer applicable places
Ultraviolet sterilization is a purely physical disinfection method with no secondary pollution, so it is suitable for a variety of fields that require disinfection, such as hospitals, research institute laboratories, electronics manufacturing, medicine, various beverages, beer 그리고 food processing, tap water disinfection, etc.
Compared with traditional disinfection technology, ultraviolet disinfection technology has overcome the shortcomings of traditional disinfection technology. In addition, in the process of disinfection, no chemical substances are added and no harmful toxins are left. It has an excellent disinfection effect.

Sterilizing device of the ultraviolet food sterilizer
1. Effective Radiation of Ultraviolet Light Source. The lamp length is 900mm, and the effective light distance is 950mm.
2. 16 * 20W ultraviolet lamp tubes are equipped in all directions from top to bottom, and 360 degrees are sterilized in all directions. In addition, each tube is equipped with a separate control switch that can be operated independently.
Protection device
- Overvoltage and Overcurrent Protection. The over-current protection device is that when the power supply voltage is higher than a certain value, the protector cuts off the line; when the power supply voltage restores to the normal range, the protector automatically turns on. The overvoltage protection device is that when the current exceeds the set current, the device automatically powers off to protect the equipment.
- Fault alarm alert. When the equipment fails, the alarm device will give an alarm for the first time to minimize the damage value.
- Equipment overload protection. When the carrying weight of the conveyor belt exceeds the normal range, the equipment will automatically remind you to avoid damaging the machine.
Characteristic of the UV light for food sterilization
- It can quickly and effectively kill all kinds of bacteria, viruses, and other microorganisms.
- Chloride in water can be effectively degraded by photolysis.
- Simple operation and convenient maintenance.
- Small area and large capacity.
- No pollution, strong environmental protection, no toxic and side effects.
- The investment cost is low, the operation cost is low, and the equipment installation is convenient.
- Using the optical principle, a unique inner wall treatment process was designed to maximize the use of ultraviolet radiation in the chamber, and the bactericidal effect was doubled.
Usage notices
- Ultraviolet disinfector is strictly prohibited from starting frequently, especially in a short time.
- According to the water quality, the ultraviolet lamp tube and quartz glass sleeve need to be cleaned regularly. Moreover, the test tube should be wiped with an alcoholic cotton ball, or gauze, to avoid affecting the ultraviolet transmittance.
- When replacing the lamp tube, please check whether there is water leakage, and then plug in the power supply. Be careful not to touch the quartz glass of the new lamp tube with your fingers, otherwise, the sterilization effect will be affected by the stain.
- Preventing ultraviolet radiation. Ultraviolet radiation also has an effect on the human body to some extent. When starting the disinfection lamp, we should avoid direct radiation on the human body. If necessary, we should use protective glasses. We should not directly face the light source with the eyes, to avoid burning the eye film.
Pay attention
- Shipment. The food sterilization machine is shipped in wooden cases to reduce the risk of wastage during transportation. Generally, small machines can be transported nearby for only 3-8 days. If you customize a special machine model, we need extra time to make the machine or its parts, which takes a little longer, but most of it is controlled within 30-50 days.

How long does it take for ultraviolet light to kill bacteria?
Ultraviolet rays can cause irreversible damage to bacterial DNA. For different bacteria, the sterilization time required is not the same. The following schedule will tell you the exact time required for sterilization:
How does a UV sterilizer work?
Ultraviolet radiation is an invisible light wave, which exists outside the violet end of the spectrum, so it is called ultraviolet radiation. Each ultraviolet photon with a wavelength of 253.7 nm has an energy of 4.9 eV. When ultraviolet rays irradiate microorganisms, energy transfer and accumulation occur, which results in the inactivation of microorganisms, thus achieving the purpose of disinfection.
When bacteria and viruses absorb more than 3600-65000uW/c, they can destroy deoxyribonucleic acid (DNA) and nucleonucleic acid (RNA) of bacteria and viruses. They can make bacteria and viruses lose their viability and fecundity, and then destroy bacteria and viruses, so as to achieve the effect of disinfection and sterilization.
On the one hand, ultraviolet radiation can mutate nucleic acid, hinder its replication, transcription blockade and protein synthesis; on the other hand, the production of free radicals can cause photoionization, leading to cell death. The sterilization principle of the ultraviolet food sterilization machine is to destroy the cell structure of the bacterial virus or the like by using ultraviolet rays.
The bactericidal intensity is proportional to the irradiation intensity of the lamp tube and inversely proportional to the distance of the irradiated disinfectant. When the irradiation intensity is constant, the longer the irradiated disinfectant stays, the closer it is to the germicidal lamp, the better its germicidal efficacy, and vice versa.
The machine body is made of mirror stainless steel, reflecting ultraviolet rays 360 degrees in all directions, and maximizing the intensity of ultraviolet radiation. In addition, the sterilization time is controlled within 3-5 minutes, which fully guarantees the sterilization time.
