<p>A system for providing an iced alcoholic beverage such as iced beer or carbonated soft drink includes a source of chilled coolant (16), and a beverage line (10) for supplying the beverage. A heat exchanger (20) is disposed in the beverage line (10) for cooling the beverage by heat transfer to the chilled coolant. A restriction (22) or orifice forming a venturi is provided in the beverage line (10) downstream from the heat exchanger. A chilled font (18) for further cooling the beverage is provided downstream from the orifice. The font (18) includes a dispenser tap (30) capable of dispensing the beverage at a relatively low dispense rate and at a relatively higher dispense rate. In use the beverage is first dispensed at a relatively low dispense rate through a smaller orifice of a narrow diameter at a preset low flow rate of beverage, and becomes ice or slush (40). After a period of time the liquid beverage, which may contain ice in the form of flakes, slush, crystals or the like is dispensed at a faster rate, typically through a larger diameter orifice.</p> |
