Pulsed bright light sterilization, what is the status of this field?

Pulsed strong light has been successfully used in air disinfection, food and beverage sterilization. Because of its sterilization speed, has a unique advantage, and will not change any ingredients of the material, does not affect the color and taste of the material. Now it is successfully used in polypeptide protein sterilization, juice sterilization, its equipment investment cost and operating cost will be greatly reduced, compared with the ultra-autoclave sterilization, pasteurization cost is lower.

Pulsed xenon lamp is the main xenon lamp in the market. The basic bactericidal principle relies on extreme power to heat the cell fluid inside the bacteria to boil and then to burst the bacteria from the inside to die. The most popular scenario is the food packaging industry. But there are also some disadvantages, such as because the power of the lamp is larger, it will have a certain heating effect on the packaging material, so the packaging material is treated with a certain limit. The other is that the internal contamination caused by the burst of bacteria may certainly change the taste of the food, even some unknown effects. There is also the pulse sterilization equipment price is much higher than UV lamp equipment, power consumption is larger. So this kind of technology is far less popular than ultraviolet sterilization equipment.

However, intense pulsed light has a wide range of applications. Pulsed strong light technology is a kind of pulse engineering technology using instantaneous discharge and special inert gas lamp, which stimulates intense white light in the form of pulse and uses instantaneous and high-intensity pulsed light energy to kill all kinds of microorganisms.

Applicable to:

In the field of water treatment, it can effectively kill bacteria, viruses and other microorganisms in water;

In the field of air sterilization, pulsed strong light can effectively decompose all kinds of chemical pollutants in the air and kill all kinds of harmful microorganisms;

In the field of food and beverage sterilization, the chemical composition and nutritional characteristics of food treated by pulsed light have no significant changes, which does not affect the taste, effectively reduces the number of microorganisms on the surface of food, and can passivate enzymes in food.

Object surface field, pulsed strong light to object surface sterilization is significant, can be applied to public places sterilization, household sterilization, and medical sterilization and so on;

In the field of greenhouse planting, irradiation of greenhouse plants can increase photosynthesis, promote plant growth, and have the effect of sterilization and insect control;

In the field of light curing, pulsed strong light curing has faster treatment time, better effect and higher controllability than the traditional ultraviolet curing, which greatly improves the working efficiency. Great potential for development.
