Ultraviolet Disinfection

There are several methods available to disinfect food stuffs of bacteria in the world today. Let’s discuss the various ways this is possible and in which applications ultraviolet would be the superior choice.

 

Traditional methods of disinfection require chemicals and considerable amounts of water. In the last few years, companies have started to employ less conventional methods of disinfection:

  • Enzyme Products

The use of enzyme products has been rising about 30% per year in the last few years. Enzymes perform the same cleaning operations as an alkali detergent and enzymes are less aggressive to the materials, uses and the environment.

  • Cryogenics

Ice or dry ice gets projected by a compressed air stream which results in a combination of mechanical shock and severe temperatures.

  • Ultrasounds

Cleaning liquids and sound waves are used to clean and disinfect items.

  • Ozone

Ozone is a very popular option at the moment but this technology is still in its infancy. Ozonated water can be used to kill bacteria.

  • Pulsed Light

A different application that uses UV technology. Intense pulsed light and extremely short pulses work to destroy micro-organisms.

High performance ultraviolet light is able to successfully disinfect equipment, water, air, surfaces and food and bacteria with a relatively thin wall (i.e salmonella, listeria and e.coli) are more vulnerable to UV rays. In the food industry, UV is effective in meat, dairy and baking applications.

 

Using UV in a germicidal capacity has not only proven effective but has become the preferred solution for the nut industry, by using ultraviolet in conjunction with a vibrating conveyor. This kind of ultraviolet solution not only saves money but is also a chemical-free, environmentally friendly and hardworking way to disinfect with extremely low maintenance and costs.

UV+IR Engineering manufactures such a solution and has been proven to work on various types of nuts and food. UV+IR is also constantly testing this solution on various types of food. Feel free to contact us to see if this solution can work for your application.
