Ozone Bottle Disinfection Western Cape

“Bottle rinsing and filling machine disinfection
Bottle rinsing with ozone was one of the first ozone applications for industrial use. It was an attractive alternative to chemicals and heat. Today, it is widely used as an integrated part of complete bottle rinsing and filling machines.

Bottle rinsing with ozone
In cases where non-sterilized bottles are filled with beer, soda, or water, the inside of the bottle or can surfaces need to be sanitized or pasteurized after the filling process. It is especially important to reuse bottles that do not come sterilized by the supplier.

Ozone versus chemicals
While some disinfection chemicals are common in the brewery industry, such as peracetic acid or hypochlorite, they leave residues after use which inevitably affect the taste and product quality. Such chemicals can be removed by rinsing, however, this may introduce unwanted particles or microorganisms which occur naturally in the supply water. Ozone use for bottle or can rinsing will solve both of these potential problems.

Ozone is the most effective commercially available disinfectant for industrial use. Hence, at very low concentrations it will sanitize bottle surfaces quickly. In addition, it leaves no chemical by-products which eliminates the risk of spoilage. You can read more about ozone as a sanitizer at our Disinfection web page.
Ozone versus heat
In many cases, bottles and cans are pasteurized at temperatures up to 100 degrees C (212 F) following beverage filling for a number of minutes. This ensures that unwanted microorganisms are inactivated. Bacteria and other microbes are the major cause of spoilage. While heat is an effective way to ensure product quality, it may affect unique tastes and aromas. Ozone offers an alternative that preserves the brew without chemicals or heat. Since ozone is applied cold, it is a major cost-saving operation compared to energy-intensive pasteurization.

Practical use
Ozone concentration and time of sanitation should be suitably balanced during bottle rinsing. The time and concentration, referred to as the CT value in min.mg/L, to inactivate potential bacteria inside the bottles or the supply water depends on what strains of microorganisms. Normally actual ozone concentration during application should not exceed 1 ppm and should not be lower than 0.2-0.4 ppm to achieve an effective result with at least a 3 log reduction of spores, bacteria or protozoa. Aqueous ozone is sprayed into the bottles through built-in nozzle. Ozone quickly reverts back to its natural state: oxygen and does not elevate the oxygen levels that would normally be found in typical tap water.”
