Abstract: To defrost one barrel of a two barrel FCB dispenser, a refrigeration system defrosts the one barrel, while neither defrosting nor chilling the other barrel, for either a selected time or until a frozen beverage is drawn from the other barrel, whichever occurs first. Once the selected time or beverage draw occurs, the refrigeration system chills the other barrel until beverage within it is properly frozen, while neither defrosting nor chilling the one barrel. Once beverage in the other barrel is properly frozen, the refrigeration system resumes defrosting the one barrel, whereupon the foregoing cycle is repeated until defrost of the one barrel is complete, at which point the refrigeration system chills the one barrel to refreeze product in it. The arrangement keeps beverage in the other barrel properly frozen during defrosting of the one barrel.

Abstract: A refrigeration system for a frozen product dispenser is controlled to have a variable cooling capacity that is determined by variable cooling load demands of the dispenser. This is accomplished, in part, by providing the refrigeration system with a variable speed compressor and one or more adjustable expansion valves for metering refrigerant to associated evaporators that are heat exchange coupled to associated freeze barrels of the dispenser, and by controlling the metering setting of the expansion valves and the speed of operation of the compressor in accordance with the cooling load demands of the dispenser. The arrangement provides for efficient operation of the refrigeration system from an energy standpoint and for a reduction in on/off cycling of the system.

Abstract: A frozen product dispenser is characterized by at least two product freeze barrels for receiving product therein and for freezing the product for dispensing, and a refrigeration system for chilling the at least two barrels. The refrigeration system has at least two evaporators for and heat transfer coupled to each barrel, separate and controllable expansion valves each having an outlet coupled to an inlet to an inlet to an associated one of the evaporators, at least two compressors having outlets coupled to inlets to the expansion valves and inlets coupled to outlets from the evaporators, and at least one condenser in fluid circuit between outlets from the compressors and inlets to the expansion valves.

Abstract: An ice dispense system for an ice dispenser is characterized by a chute having an ice receiving upper end in communication with an ice bin outlet passage and an ice dispensing lower end. Beginning with the chute filled with ice and its lower end closed, to dispense a selected quantity of ice, the chute lower end is opened for one of a plurality of different time periods, where each individual time period of the plurality is of a duration to dispense from the chute an associated predetermined quantity of ice. In response to dispensing ice from the chute, an agitator in the bin is operated for one of a plurality of different time periods, where each individual time period of the plurality is of a duration to move through the bin outlet passage and into the upper end of the chute an amount of ice substantially equal to that dispensed. The ice dispensing system is provided with an improved user interface and user programmable features.

Abstract: An adaptive defrost control for a frozen product machine implements an algorithm that utilizes various operating parameters of the machine to adaptively adjust the time interval between successive defrost cycles in a manner such that defrost cycles occur only on an as-needed basis. The adaptive defrost control minimizes the time during which the machine is in a defrost cycle, thereby maximizing the uptime of the machine during which frozen product can be prepared.

Abstract: A beverage dispensing system is characterized by a beverage dispenser and a beverage dispensing tower located remote from the beverage dispenser. The beverage dispenser has a cold plate and the tower has a heat exchanger. To deliver chilled beverage components to and for dispensing by the tower, a closed-loop water circulating circuit extends between and includes a fluid chilling circuit of the cold plate and a heat exchange circuit of the heat exchanger. The closed-loop circuit is fluid coupled to a beverage valve of the tower to deliver chilled water to the valve, and a supply of beverage syrup is fluid coupled to the tower valve through a fluid chilling circuit of the heat exchanger for delivery of chilled syrup to the valve for mixing with chilled water in the dispensing of a beverage from the tower valve.

Abstract: A beverage dispensing system is characterized by an ice/beverage dispenser and a remote beverage tower. The dispenser has a cold plate, a carbonator pump and a carbonator tank and the tower has a carbonator tank. To chill the tower carbonator tank, a closed loop fluid circuit extends between and heat exchange couples the dispenser cold plate and the tower carbonator tank. The dispenser carbonator pump can be used to circulate water through the closed loop circuit or a carbonator pump for the tower can be used for the purpose. A valve arrangement is provided for and as part of the dispenser cold plate to conveniently enable the dispenser to be switched between stand-alone operation and operation as a base unit for the remote tower. Arrangement is also made to cause ice agitation at the dispenser in response to drinks dispense at the remote tower to maintain a supply on the cold plate.

Abstract: A beverage dispensing head for a beverage dispenser admixes diluent and syrup for dispensing into a cup. The dispensing head has a nozzle with a diluent receiving surface that leads downward to a juncture of the surface with an outlet from the nozzle. Diluent delivered to the dispensing head is introduced onto the diluent receiving surface for flow along the surface to and past the juncture. Syrup delivered to the dispensing head is emitted in the nozzle as a plurality of discrete streams directed toward and against diluent at the juncture for admixture with the diluent. The admixture of diluent and syrup then exits the dispensing head nozzle through the nozzle outlet for being dispensed into the cup.

Abstract: A control system for an icemaker for an ice/beverage dispenser is responsive to both a sensed level of ice in an ice bin of the dispenser and to a customer ice usage profile to operate the icemaker at such times as to build ice for the ice bin just before and in sufficient time and quantity to meet an anticipated demand for ice. The control system may be programmed manually or automatically through use of adaptive algorithms, with ice usage patterns that identify the days and times of day when demands for ice will occur, and the control system then operates the icemaker in accordance with such ice usage patterns.
