    Abstract: A method for simultaneously carbonating and cooling a liquid beverage. The apparatus used for the method includes an upright enclosed vessel with an upright coaxial carbonating column within the same and spaced therefrom to define an upright channel. A source of liquid to be carbonated and liquid carbon dioxide are directed into the lower end of the carbonating column and the product overflows the carbonating column into the annular channel wherein it passes downwardly and out of the vessel. A bypass line of ambient liquid is sprayed onto the top of the carbonating column to dissolve floating ice crystals. Also, a screen is placed between the carbonating column and annular channel to prevent passage of such ice crystals.
