<p>A beverage dispenser (10) comprises a housing (11) which defines a cooling chamber (12) and has dispensing nozzles (16A-D) mounted thereon, a water line (14) positioned in the bottom of the cooling chamber (12) for communicating water to the dispensing nozzles (16A-D), product lines (25-28) mounted in the front of the cooling chamber (12) for communicating product to the dispensing valves (16A-D), a refrigeration unit (13) mounted over the cooling chamber (12) which includes an evaporator coil (35) extending into the cooling chamber (12), and an agitator motor (37) mounted over the cooling chamber (12) for driving an impeller located within the cooling chamber (12). The cooling chamber (12) contains a cooling fluid, a portion of which freezes about the evaporator coil (35) during operation of the refrigeration unit (13) to form a frozen cooling fluid slab. A frozen cooling fluid bank controller controls the size of the frozen cooling fluid slab, while mounting of the controller's probe (39) to the side of the evaporator coil (35) facing the front of the housing (11) prevents the frozen cooling fluid slab from freezing to envelope the product lines (25-28).</p> |
