Ultraviolet ray sterilization and its application field

Iwasaki Electric's “Ultraviolet ray sterilization system” is a very effective sterilization method which uses ultraviolet rays that work towards the DNA of the microorganism and inhibit microbial reproduction.

Now, Shifting To Ultraviolet Sterilization

In modern society, chemical substances are used in various fields but we can't imagine how much of those would affect the human body and environment. It is natural to think it's desirable not to use chemicals for sterilizing foods and containers from the long-term perspective of the future of humankind. Iwasaki Electric's “Ultraviolet ray sterilization system” is a very effective sterilization method which uses the ultraviolet rays that work towards the DNA of the microorganism and inhibit microbial reproduction.

Achieved Production of High Level Clean Products

“Ultraviolet ray sterilization system” can meet the needs for the era where a high hygiene level is required. For food and medical products manufacture, there is GMP (Good Manufacturing Practice) which is the hygiene standard in every step of the way such as facility, equipment, appliances, machinery, manufacturing processes, workers and finished products. Especially for food, the HACCP (Hazard Analysis Critical Control Point) which is a scientific management system is adopted from the raising of raw material of food, their production, manufacturing and processing, storage of the product, logistics, to final distribution to the customers. The ultraviolet ray sterilization supports these kinds of hygiene management with its compact size and is a very efficient sterilization method that doesn't require the secondary treatment.

Issues with alternative sterilization methods

Heat sterilization:

• Not suitable for heat-resistant bacteria
• May cause material changes in the object being sterilized
• High energy costs
• Requires a cooling process, facilitating bacterial adhesion

Chemical sterilization:

• Remnants require secondary treatment
• May lead to development of resistant bacteria

Ozone sterilization:

• Harmful to people
• Long processing times required at low concentrations
• Oxidation can lead to corrosion of metals
• Long processing time required against heat-resistant bacteria and fungi

Benefits of UV sterilization

Benefits 1

Effective against all types of bacteria

Benefits 2

Minimal risk of altering the physical properties of the object

Benefits 3

Compact device, and low maintenance costs

Benefits 4

No secondary processing required, which simplifies the process, and reduces time and costs

Benefits 5

Can be sterilized at room temperature

Benefits 6

Does not create resistant bacteria
