Anyone who has tapped a beer themselves knows that the head can be quite a challenge - it shouldn't be too big or too small. However, foam is usually unpopular when filling beer into cans or bottles. When foam forms, the oxygen bound in the foam can lead to a higher oxygen content - known as the TPO value - and thus affect the properties and, in particular, the shelf life of the beer. The beverage industry has developed various solutions to this problem. One of these is bubble breakers, which blow off the foam with CO2. However, some of the beverage is lost in the process, especially in older filling systems - this can quickly amount to up to two milliliters per can. What sounds like little at first glance adds up considerably at filling speeds of up to 130,000 cans per hour.

The filling system is controlled by a Simatic S7-1200, which communicates via Profinet. The system can be conveniently operated using a latest-generation Unified Comfort Panel. The Sitop power supply, which is established worldwide for demanding industrial applications, is also used. In the future, the ultrasonic system will help to further optimize production processes and reduce costs by using machine data thanks to Industrial Edge.

Operation is intuitive with an appealing visualization. Thanks to the integrated recipe management, the system can be easily set up before production starts. Relevant data can be archived.

Feldschlösschen, Switzerland's leading brewery based in Rheinfelden, also relies on innovative ultrasonic technology. At Feldschlösschen, the system is used on a line that fills up to 60,000 cans per hour. Measurements have shown that Feldschlösschen can save several tons of CO2 per year. Gaby Gerber, Head of Corporate Communications & Public Affairs at Feldschlösschen, comments: “Reducing CO2 emissions is one of the focal points of our sustainability strategy. We have achieved our interim target from 2017: by the end of 2022, 75% of our fuel requirements in Rheinfelden were covered by our own renewable energies, and we have the fifth lowest CO2-equivalent emissions per hectoliter of beverage within the Carlsberg Group. We were able to reduce the relative CO2 emissions of our value chain by 14% in the same period.” Feldschlösschen is aiming for net zero CO2 emissions along the entire value chain by 2040. To achieve this, the company is making its logistics CO2-neutral, relying on recyclable packaging, using the latest technologies for refrigeration appliances - and using ultrasound instead of a CO2 bubble breaker.
