Ultraviolet food sterilization machine sterilizing device

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

1. 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.
2. Fault alarm alert. When the equipment fails, the alarm device will give an alarm for the first time to minimize the damage value.
3. 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.

How does a UV sterilizer work?

Ultraviolet light is a high-energy electromagnetic wave with a wavelength between 200-280nm, possessing extremely potent sterilizing properties. When microorganisms are exposed to ultraviolet radiation, their DNA and RNA absorb energy, causing breaks and mutations that prevent replication and reproduction.

Ultraviolet sterilization units emit ultraviolet photons at a wavelength of 253.7nm through high-frequency lamps, destroying the genetic material of bacteria and viruses within mere tens of seconds to achieve complete inactivation.

The unit features a mirror-finished stainless steel reflective chamber design. Ultraviolet light undergoes multiple reflections within the chamber, achieving 360° comprehensive irradiation to ensure uniform sterilization. High-intensity sterilization is typically completed within 3-5 minutes, providing safety assurance for food and pharmaceutical production.

Usage notices

1. Ultraviolet disinfector is strictly prohibited from starting frequently, especially in a short time.
2.  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.
3. 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.
4. 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

1. Shipment. The ultraviolet 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.
2. About after-sales. The warranty period is two years. During this period, if you have any quality problems, please contact our online customer service to reflect the situation, we will provide you with a warranty or replacement service.
3. Generally speaking, the conveyor belt of this machine is the Teflon mesh conveyor belt. By the way, but if you have special needs, such as handling some powdered goods, you can customize the PVC transparent conveyor belt.

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:
