Estimating the term…
The invention relates to a beverage cooler having an in-line operating cooling unit for instant cooling of beverage flowing through the same, comprising a cooling container (5) having an inlet (10) and an outlet (11), for feeding the beverage to and from the cooling container, respectively, and a cooling tube (14) located inside the cooling container. The cooling container (5) is adapted to be located in an ambient temperature which is above the freezing point for the beverage, wherein the cooling tube (14) is adapted to carry a cooling fluid having a temperature below the freezing point of the beverage and is located such that the beverage can pass between the cooling tube and an outer wall of the cooling container (5). Hence, the beverage will pass by the cooling tube and be cooled from it and freeze to solid phase in the area closest to the cooling tube, whereas the outside of the cooling container, having a temperature above the freezing point of the beverage, will ensure a free passage of non-frozen beverage closest to the outside wall of the cooling container.
A beverage cooler having an in-line operating cooling unit for instant cooling of beverage flowing through the same, comprising a cooling container having an inlet and an outlet, for feeding the beverage to and from the cooling container, respectively, an inner tube located inside the cooling container, and a cooling tube extending through the inner tube, wherein the cooling container is adapted to be located in an ambient temperature which is above the freezing point for the beverage and the cooling tube is adapted to carry a cooling fluid having a temperature below the freezing point of the beverage and is located such that the beverage is present and can pass between the cooling tube and an outer wall of the cooling container, and wherein the cooling container is adapted to be, filled with frozen and unfrozen beverage such that the cooling container has no unfilled space, and wherein the inner tube is configured such that the beverage passing through the cooling container flows both through the inner tube and outside of the inner tube between the inner tube and the outer wall of the cooling tube.
A method for cooling beverage, comprising the steps of:
A beverage cooler having an in-line operating cooling unit for instant cooling of beverage flowing through the same, comprising a cooling container having an inlet and an outlet, for feeding the beverage to and from the cooling container, respectively, an inner tube located inside the cooling container, and a cooling tube extending through the inner tube, wherein the cooling container is adapted to be located in an ambient temperature which is above the freezing point for the beverage, wherein the cooling tube is adapted to carry a cooling fluid having a temperature below the freezing point of the beverage and is located such that the beverage is present and can pass between the cooling tube and an outer wall of the cooling container, and wherein the cooling container is adapted to be, filled with frozen and unfrozen beverage such that the cooling container has no unfilled space, wherein the cooling tube is adapted to contact the beverage and wherein the inner tube is configured such that the beverage passing through the cooling container flows both through the inner tube and outside of the inner tube between the inner tube and the outer wall of the cooling container.
