ABSTRACT:
Automatic dispensing apparatus for dispensing predetermined quantities of different beverages from one dispensing station, the invention comprises a housing having a water supply subsystem located therein for supplying either hot or cold water to the dispensing station for ejection into a cup, the housing further having a plurality of dry powder beverage base containers, each container having a powder metering mechanism for ejecting a predetermined quantity of powder into a delivery chute, the delivery chute directing the powder into the cup for mixing with the hot or cold water. Portions of the powder metering mechanisms remote from the containers and upper portions of the delivery chutes, one delivery chute being provided for each container to avoid cross-contamination, are disposed within a warm air enclosure to prevent moisture contamination of the dry powders. A warm air flow subsystem heats the warm air enclosure and, by producing a positive pressure therein relative to ambient pressure at the lower ends of the delivery chutes, prevents the movement of moisture-laden air upwardly through the delivery chutes into contaminating contact with the container and the dry powders contained therein.
