The pasteurizer tunnel<\/b><\/strong>\u00a0is core continuous thermal treatment equipment for bottled and canned beer and beverages. It uses gradient temperature zones to complete preheating, pasteurization holding, gradual cooling and drying, achieving commercial sterility while preserving flavor, carbonation and nutrition.<\/p>

A beer tunnel pasteurizer<\/b><\/strong>\u00a0is specially optimized for bottled\/canned beer to protect foam, aroma and taste stability. A beverage tunnel pasteurizer<\/b><\/strong>\u00a0serves juices, tea drinks, RTD coffee, dairy drinks, CSDs and other non-alcoholic products.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
