A control system and associated method for controlling the ice volume fraction of a circulating ice-containing medium. The control system comprises a freezer apparatus 1 for generating an ice-containing medium and a pump 2 for circulating the ice-containing medium through a flow circuit comprising an outward line 3, a main line 14 and a return line 4. A bypass line 5 connects the outward line and the return line to form a bypass circuit. In use, the time taken for circulating ice-containing medium to pass through the bypass circuit is less than the time taken for circulating ice-containing medium to pass through the flow circuit. Ice sensors 10, 13 may be used to measure the ice fraction in the ice-containing medium. Preferably, the control system is utilised in a beverage dispense system to dispense an alcoholic beverage such as beer or cider, where a beverage ice medium may be dispensed through a valve, such as a tap (23a, fig.3). |
