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.

A beverage dispensing machine comprising a hopper holding a supply of particulate dehydrated beverage concentrate, a concentrate dispensing means connected with the hopper; said dispensing means has a dispensing duct with an outlet end and is intermittently operable to transport a predetermined volume of concentrate from the hopper outwardly through a dispensing duct, a funnel defining a mixing chamber receiving concentrate from the dispensing means, water supply and delivery means delivering a predetermined volume of water into the mixing chamber each time concentrate is received thereby and establishing reconstituted beverage in the mixing chamber, an outlet tube extending from the funnel to exhaust moisture-ladened air and to drain beverage from the mixing chamber, a case about the hopper and dispensing means and defining a compression chamber, an air inlet opening in the case opening to the ambient atmosphere, air pump means at said air inlet opening delivering air at greater than atmospheric pressure into the compression chamber to cool said hopper and dispensing means and the concentrate therein, an air outlet opening in the case communicating with the mixing chamber, the outlet end of the dispensing duct is positioned at said air outlet opening whereby air flowing through the outlet opening about the dispensing duct and into the mixing chamber establishes a minus pressure at the outlet end of the dispensing duct to draw air outward through and prevent the flow of moisture-ladened air inward through that duct; air moving into the mixing chamber moves out of said chamber through said outlet tube transporting beverage and moisture-ladened air out of the mixing chamber, a second case defining a condensing chamber into which the outlet tube projects, a blending trough within the condensing chamber and receiving beverage and moisture-ladened air flowing through and from the outlet tube, said trough is open whereby moisture-ladened air flows therefrom into the condensing chamber, said second case has air outlet means to exhaust air from within the condensing chamber, said second case has a lower portion defining a condensate catch basin, said trough includes a dispensing tube depending through and from the second case to drain the trough and dispense beverage from the machine.
