    • Carbonated ale is pumped by pump 50 through a device 52 for dissolving a mixture of carbon dioxide and nitrogen therein. A resulting turbulent stream of ale containing bubbles of nitrogen and carbon dioxide flows through a chiller 54. The ale leaves the chiller 54 in the form of a foam. The foam is allowed to subside in a tank 56 in which the ale is held under a nitrogen pressure for at least ten minutes. The ale substantially free of foam is passed to a filler 64 from which it is charged into flexible, thin-walled cans which are then closed. In each can, after its closure, dissolved gas comes out of solution to create therein a superatmospheric internal pressure that resists deformation of its walls during normal handling.
    • 碳酸啤酒由泵50通过用于溶解二氧化碳和氮气的混合物的装置52泵送。 产生的含有氮气和二氧化碳气泡的湍流的啤酒流流过冷却器54.啤酒将泡沫的形式离开冷却器54。 允许泡沫在罐56中下沉,其中将啤酒在氮气压力下保持至少十分钟。 基本上没有泡沫的啤酒瓶被送入填料64,从中填充到柔性的薄壁罐中,然后将其封闭。 在每个罐中,在其关闭之后,溶解的气体从溶液中排出,以在其中产生超大气压的内部压力,其在正常处理期间抵抗其壁的变形。
