There’s no doubt: the sun's rays have a strong disinfecting power. More specifically, the reproduction of natural light by ultraviolet (UV) lamps is already widely used to eliminate harmful microorganisms, particularly in the medical sector and in the environment. In the light of the coronavirus pandemic, UV radiation has become an indispensable technology for fighting the spread of the virus. After an introduction to UV sterilization, Roller Grill explains why you should use a professional UVC sterilizer in your restaurant or point of sale. Let’s fields of application, it’s really impressive!
UV sterilization is a purely physical and natural treatment. It kills bacteria by exposing them to a specific wavelength of UV rays as the sun does on our planet. This simple technology thus reproduces the bactericidal action of natural light thanks to UV radiation lamps. Used without the addition of chemicals, this sterilization method is environmentally friendly.
The work of Dr Niels Ryberg Finsen, a Danish doctor and winner of the Nobel Prize in Medicine in 1903, showed the power of disinfection and the treatment of some diseases by light radiation.
At the same time, ultraviolet rays were already known for their mutagenic action on micro-organisms in water treatment.
Especially in the 1960s, UV decontamination was developed to improve the quality of water quality eliminating microorganisms. The action can be threefold: filtering, purifying and sterilizing waste water or water from any source.
For some decades now, UV lamps have also been used for air disinfection and surface sterilization in laboratories and hospitals.
Nowadays, the food industry uses the UV disinfection process to destroy micro-organisms present on machines such as conveyor belts, but also to better preserve stored fruit and vegetables before delivery to warehouses.
The operation of UV sterilization, although unknown, is very easy to approach and understand.
Ultraviolet rays belong to an electromagnetic spectrum divided into 3 parts. Depending on the wavelength, the rays act differently:
UVC rays are germicidal at a wave length of 253.7 nm. In other words, they destroy germs and micro-organisms such as viruses, bacteria, yeasts, molds and algae.
At a wavelength of 253.7 nm, ultra-violet radiation acts directly and instantaneously through photochemical reactions on the DNA of microorganisms. It dissociates the DNA molecules, creating mutations and inactivating the cells. Pathogenic micro-organisms become harmless and are destroyed.
Depending on the duration of exposure and the quantity to be disinfected, it is a question of disinfection or sterilization. Disinfection assumes that the few microorganisms remaining after UV treatment are not sufficient to trigger a disease. Sterilization is when all the micro-organisms are killed. This stops the spread of bacteria or viruses.
UVC rays are generated by very special types of lamp: mercury vapour lamps or LED UVC lamps. These highly efficient fluorescent lamps emit germicidal radiation with a wavelength of 253.7 nm without altering the properties of the product. The germicidal efficiency of a UVC lamp varies between 90% and 99.99% depending on the dose of UVC radiation (in mJ/cm-²), i.e. the amount resulted from the lamp power by the exposure time.
The tried and tested UVC sterilizer has just been introduced in hospitality.
Roller Grill launches the first professional UVC sterilizer with dual ultraviolet radiation sources. This professional quality sterilizer allows complete disinfection of all types of objects (plates, dishes, kitchen utensils, room keys...) without turning them over.
Roller Grill's professional UV sterilizer eliminates 99.99% of pathogenic micro-organisms: bacteria, viruses and yeasts. The power of both UV LED lamps combined with an exposure time of 7 minutes ensures the destruction of germs and all pathogenic micro-organisms on the objects presented in this professional equipment.
The professional electric sterilizer UVC 120 Roller Grill is designed primarily for decontamination of:
This professional sterilizer is an essential electrical equipment for hospitality in the framework of the good respect of sanitary measures.
This UV sterilization unit is perfectly suitable for professional use in other industries, such as:
