Autofill device applicable to the mixing bowl of a granita or chilled beverages dispenser

Abstract

Granita ices or chilled drinks made from water and a liquid flavoring are mixed in a dispenser equipped with an autofill device that comprises a module packaged in a housing positionable directly on top of the bowl from which the iced or chilled product is dispensed. Water is directed into the module through first feed pipelines, and flavoring through second feed pipelines, whereupon the two liquids are directed along a further pipeline from the respective feed pipelines into the bowl. The presence of the water and flavoring is detected by sensors located on the feed pipelines or the outlet pipeline, or both, and further sensors monitor the level of the mixture in the bowl; a control unit interlocked to the presence sensors will activate a solenoid valve on the first pipelines, and a pump on the second pipelines, to replenish the bowl with the requisite quantities of water and flavoring automatically.
