Abstract: An arrangement for a beverage dispenser carbonation unit generally comprises a two-part cold plate for cooling fluids. The first part is cooled by ice contained within an adjacent ice bin. The second part is cooled by proximity to the ice within the ice bin as well as a fluid conveyed through the first part and then the second part. The second part of the cold plate comprises a sleeve, preferably integral therewith, for receiving a carbonator unit and maintaining the carbonator unit at a reduced temperature. A re-circulation pump is provided for conveyance of the fluid between the two parts of the cold plate.

Abstract: A dispenser with features for enhanced maintainability generally comprises a lower unit having therein an ice bin; an upper unit atop the lower unit for providing an interface for dispensing ice from the ice bin to the public; a conveyor having and inlet in the ice bin and an outlet in the upper unit; an ice distributor in a lower portion of the ice bin for conveying ice within the ice bin to the inlet; and a drive motor operably associated with the ice distributor, the drive motor being located in a space above the lower unit for ready access. A plurality of optical emitter assemblies are disposed upon a wall of the ice bin and a plurality of optical receiver assemblies are oppositely disposed upon a second wall of the ice bin. Each optical emitter assembly comprises an emitter housing and a selectively removable emitter body comprising an optical source. Each optical receiver assembly comprises a receiver housing and a selectively removable receiver body comprising an optical receiver.
