When it comes to keeping your bottles clean and free of contaminants, there are a few different methods that you can use. In this blog post, we will discuss the benefits of using ozone for bottle rinsing over chemical solutions. Ozone generators are a great way to get your bottles clean and help to protect from potential contaminants. Keep reading to learn more about how ozone generators can benefit your brewing process!
One of the first cases of industrial usage for ozonation was with a bottle rinsing machine. It was an appealing alternative to chemicals based solutions. Today, it is commonly implemented as an element of entire bottle washing and filling systems.
When drinkable non-sterilized bottles are filled with beer, soda, or water, the interior of the bottle or can must be cleaned or pasteurized after filling. It is especially critical for reusable bottles that do not come sterile from the manufacturer.
Ozone Vs. Chemicals
Although some disinfection chemicals, such as peracetic acid or hypochlorite, are widely used in the brewing sector, they leave residues after usage that have an impact on taste and product quality. These chemicals may be removed by rinsing, but this might introduce undesirable particles or germs that are present in the water supply. Ozone treatment for bottle or can washing will address both of these issues.
Ozone is the most effective commercially available disinfectant for industrial application. It quickly sanitize bottle exteriors at very low levels. It also leaves no chemical by-products, reducing the chance of spoiling.
Following beverage filling for a number of minutes, bottles and cans are pasteurized at temperatures up to 100 °C (212 °F). This ensures that harmful microbes are destroyed. Spoilage is caused by bacteria and other organisms. Heat, while helpful in maintaining quality, may alter the unique characteristics and fragrances of food products. Ozone is a non-chemical alternative that maintains the brew without using chemicals or heat. Because ozone is delivered cold, it saves money over pasteurization because no heat is required.
Practical Use of Ozone in Bottle Rinsing
During bottle rinsing, the level of ozone and the time spent sanitizing should be properly balanced. The length and concentration of disinfectant used to inactivate bacteria inside bottles or supply water is determined by specific types of microorganisms. It is essential to note that the soil paste will be very wet after application, thus it should not be dumped into open containers or allowed to dry out in any area where pests are present.
On average, actual ozone concentration during application should not exceed 1 ppm and should not be lower than 0.2-0 on a 3 log reduction scale for at least 3 log reduction of spores, bacteria, or protozoa to obtain an effective result. Aqueous ozone can be sprayed directly into the bottles.
