A common disinfectant in the food processing industry is chlorine. This substance is mixed with water, obtaining chlorinated water to be used as a disinfectant. It has been shown that some microorganisms such as E.coli and Giardia can develop resistance to chlorine over time. This becomes a great inconvenience, because it is a less effective tool than it was expected.
Another disadvantage presented by both chlorine and other chemical substances is the effect that it causes in equipment made out of metals and wood. The steel components, constantly exposed to chlorinated water, end up shortening their useful life, causing an increase in the cost of production due to the high prices of some of this equipment.
For example, the wooden wine barrels used in the wine industry also end up damaged by the aggressiveness of these chemicals. Winemakers take special care to choose high quality wooden barrels to age the wine. This wood can be damaged or altered to the point where it ends up not serving its original purpose.
Its application in liquid state
Ozone can be dissolved in water such as chlorine and other chemicals. In many plants, aqueous ozone is already used, applied through ozone injection systems, especially in the disinfection of food products. The aqueous ozone can be sprayed onto the products inside the plant itself, safely. Equipment, walls, floors, bathtubs, drains, tanks, shelves, knives and tables can be sprayed with aqueous ozone. Closed pipes can also be perfectly disinfected with ozone using a system called Clean in Place (CIP).
A process in 2 steps
To carry out sanitation through ozone, a two-step process is usually required. The surfaces are cleaned and the biofilms (that type of accumulation of the microbes that we talked about in a previous article) are removed with hot water or a cleaner. Then, the aqueous ozone is used to disinfect the surface and destroy all bacteria, viruses, fungi and spores. It is not necessary to apply any other cleaning phase after the use of ozone. In fact, it is not necessary to even rinse, since ozone will leave no residue on the surface. This, in addition to being more effective, reduces the cleaning time, prevents corrosion of the materials and achieves a saving in water consumption.
Ozone can be used throughout the day during processing. And since there is no danger of damaging the products, in the absence of harmful and aggressive chemicals, ozone can be used without any problem to disinfect the equipment, as they are in use. Therefore, the downtime is reduced, allowing the company to establish more production hours.
