ZHANGJIAGANG CITY XINMAO DRINK MACHINERY CO., LTD.’s advanced beer filling machines feature multiple filling modes to accommodate diverse beer styles. The flexible systems support isobaric filling for carbonated beers (e.g., lagers, IPAs), maintaining CO₂ levels during filling; gravity filling for still or low-carbonation beers (e.g., stouts, porters); and vacuum filling for sensitive craft beers requiring minimal oxygen exposure (e.g., barrel-aged ales). Each mode is adjustable via the PLC control panel, allowing quick switching between recipes without mechanical modifications. Additionally, the machines can integrate nitrogen-purging modules for nitro beers or handle mixed packaging (glass bottles + cans) with optional changeover kits. This versatility makes them ideal for breweries producing a wide range of beer styles under one system.
