Soft drinks

Why do we need filtration in the soft drink industry?

All beverages classified as “soft drinks” are those manufactured using water or mineral water, sugar, scents, and essences. They typically contain carbon dioxide.

The production of other beverage products, including flavored water, sports, energy drinks, and ice teas, is made using a similar procedure.

The biggest problem the soft drinks producers need to concern with is preventing bacteria and microorganisms in the whole production process. Because all these bad contaminants can not only result in a terrible taste and flavor but also cause illness.

Due to the special characteristics of soft drinks, which are the high sugar level, pH level, low preservative content, and the way to produce soft drinks, contribute to the high demand for them.

Soft drinks are extremely easy to be influenced by those factors, so they are likely to be fermented and moldy.

Based on this actuality, microbial management is essential to prevent contaminants. Brother Filtration helps all soft drink producers to solve these problems, improve their efficiency and create a safer process with our perfect filtration products and technologies.

Though soft drink production processes differ by product types and applications, the basic process is the same.

What is the filtration procedure for soft drinks?

The first step is sugar syrup clarification

The syrup is a combination of sugar, water, flavorings, and essences. The syrup’s crystals and particles will be retained after clarifying.

The second step is water microbial stabilization

For beverages, water is a big part of it, so we must ensure that the water is clean and hygienic, and safe.

The prefiltration phase is very important in the whole process, that it can protect the final filter, ensure the long lifespan of equipment, provide good economic effectiveness for the filtration system and reduce initial bioburden.

Unlike prefiltration, final filtration mainly removes microorganisms such as bacteria, mold, yeast, and protozoa to achieve the required contaminant-free water quality.

The third step is carbonation

Carbonation is a step that adds carbon dioxide to drinks. The CO2 which is injected into the beverage must be free of particles and microorganisms. But notice that, non-carbonated drinks do not need this step.

The fourth step is the bottle blower and bottle washer

Obviously, for the high sanitary grade, the bottle blower, which converts the pre-forms into the finished PET bottle, uses clean air that has been filtered to make bottles with less bioburden. Any beverage production method that uses PET bottles can include bottle blowing.

The water used to rinse the bottles must be free of impurities, just as the air used in the bottle blower must be; this guarantees that the bottles are of high quality before being filled. To keep your drink’s quality and shelf life intact, you need a safe and dependable container.

The last step is bottle filler

For this filling process, we can also utilize gas filtration to fill carbonated drinks. In order to make it possible for the filling, the filler bowl must be pressurized and the gas we used must be micro-biologically stable.

Conclusion

In the production and manufacture of beverages, filtration is not only required for liquids but many gas filtration steps are also needed. A perfect filtration system is essential for the beverage manufacturing industry, not only to ensure the flavor of the beverage but also to ensure its safety and hygiene.
