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.
Claims7
In a method for simultaneously carbonating and cooling an aqueous liquid, the steps of
- a. containing a body of aqueous liquid in an upright carbonating column having a heat conductive wall,
- b. supplying aqueous liquid from a stream of aqueous liquid to be carbonated into the bottom region of said carbonating column,
- c. injecting liquid carbon dioxide into the bottom region of said carbonating column and thus carbonating and cooling the liquid from said stream,
- d. overflowing cooled carbonated liquid from the top region of said carbonating column,
- e. passing said overflowing carbonated aqueous liquid downwardly through a channel around said carbonating column extending downwardly to the level of the bottom of said heat conductive wall, to further cool the carbonated aqueous liquid in said channel by heat transfer across said heat conductive wall.
