Grape harvesting is already completed. Ripe grapes are collected and will be processed to tasteful wine. Before the liquid will be filled, the bottles need to be very clean and free of germs. Bottles and cups can be treated and disinfected with special UV radiation.
The UVC radiation, effective at wavelengths from 200 to 300 nm, has a strong bactericidal effect. It is absorbed by the DNA of microorganisms such as viruses, bacteria, yeasts or fungi, destroys its structure and inactivates living cells.
Bacteria are rendered harmless within seconds by UV light. If the irradiance is high enough, UV disinfection is a reliable and environmentally-friendly method because chemicals need not be added. Moreover, the microorganisms cannot become resistant to UV radiation. This is a special application of Heraeus Noblelight‘s UVC disinfection light.
Another solution is about UV and IR printing. After the wine has been filled into bottles, individual labels make them appealing and unique.
Printing ink needs to be completely dried or cured before the products can be labeled onto the bottles but also stacked, cut, folded or otherwise processed. Depending on the paint or ink, UV lamps or IR emitters, or a combination of both, are used for reliable drying or curing. The UV and IR solutions are precisely adjusted to the individual printing process requirements, to work as efficiently as possible, as the company pledges.
