Abstract
A beverage dispensing machine comprising a hopper holding particulate dehydrated beverage concentrate, dispensing a device including a dispensing duct intermittently transporting a predetermined volume of concentrate from the hopper out through the dispensing duct into a mixing funnel, a water supply delivering a predetermined volume of water into the funnel to establish reconstituted beverage therein, an outlet tube on the funnel to exhaust moisture ladened air and to drain beverage therefrom, a case about the hopper and defining a compression chamber, an air pump delivering air greater than atmospheric pressure into the compression chamber to cool said hopper and the concentrate therein, an air outlet opening in the case about the dispensing duct and communicating with the funnel, whereby air flowing through the outlet opening about the dispensing duct and into the funnel establishes a minus pressure which draws air outward through the duct and from the hopper and prevents the flow of moisture ladened air inward through that duct and into the hopper; air moving into the funnel moves out through said tube to transport beverage and moisture ladened air out of the funnel and tube.
