The Beer Foam Separator (BFS 900; photo) is built to be used in combination with this company’s GHS VSD+ screw vacuum pump. The BFS 900 was designed and developed in partnership with leading 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, reduced output. The CFS 900 actively solves the foam issue with its smart features and easy-to-maintain design, providing full protection to the vacuum pump and saving on costs, too. The BFS 900 is fabricated from 304 stainless steel 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 airlock consisting of electro-pneumatic actuators and a receiver tank to enable drain in continuous operation. — Atlas Copco Vacuum Technique, Cologne, Germany
