Atlas Copco BFS 900 Beer Foam Separator

Atlas Copco has introduced a solution for the beer bottling process called the Beer Foam Separator (BFS 900). Built to be used in combination with its Industry 4.0 ready GHS VSD+ screw vacuum pump, the beer foam separator is designed to improve energy efficiency, reduce lifecycle costs and lower the rejection rate of over- and underfilled bottles in the process.

The beer foam separator was designed and developed in partnership with breweries and in direct response to the excess foam production that hampered the beer filling process. The high amount of foam generated at the end of the filling process would enter the vacuum line and disrupt the process leading to poor quality and reduced output.

Designed to tackle the foam issue and provide several benefits for the overall bottling process, the unit is fabricated from 304 stainless steel for durability with an auto-draining tank and associated logic control system. When the excess foam enters the vacuum system, it is effectively collapsed in the foam separator by a calming section with a large diameter for foam settling. The rising liquid level is detected by appropriate sensors and an automatic separation process is initiated by an air lock consisting of electro-pneumatic actuators and a receiver tank to enable drain in continuous operation.

The separator is also clean-in-place (CIP) capable. A shower ball mechanism is designed to ensure reach to all internal parts, granting compliance to required hygienic standards.
