Abstract
An automated mixing drink dispenser () establishes a preselected feed rate of concentrate from a concentrate hopper () and ratio of concentrate to mixing water fed into a mixing chamber () through the Venturi effect created by swirling water fed into a mixing chamber () at a preselected water pressure () and preselected regulated flow rate () associated with the preselected feed rate of the concentrate. Concentrate is fed to a mixing chamber () from a concentrate hopper () having an open drain hole () openly connected to the mixing chamber (). A stirring mechanism () mechanically mixes the concentrate within the concentrate hopper () to maintain a uniform density and viscosity and a gas pressure mechanism () maintains a uniform head pressure of concentrate to facilitate maintenance of the preselected concentrate flow rate over time. Nitrogen gas in air is pumped through a nitrogen passing filter to fill the space () above the concentrate to both maintain head pressure and to reduce deterioration of the concentrate due to interaction with oxygen.
