Abstract
An automatic dispenser for wine has a first reservoir which holds an inverted bottle of wine and a second reservoir connected to the first reservoir through a check valve for holding a supply of wine received from the first reservoir. A solenoid actuated valve is interposed in a wine dispense line connected to the second reservoir. A source of pressurized nitrogen gas is connected to both the first and second reservoirs for supplying the discharge pressure for dispensing the wine from the second reservoir upon actuation of the solenoid, and for maintaining a nitrogen enriched atmosphere in contact with the wine at all times in the reservoirs to prevent secondary fermentation of the wine in the reservoirs by the oxygen in the air. Nitrogen is supplied automatically to the first reservoir through a demand control valve each time wine is removed from the second reservoir to occupy the space vacated by the dispensed wine. Also, manual actuation of a purge valve will supply nitrogen to the first reservoir to force most of the air therefrom and to fill any void space with nitrogen upon opening the first reservoir to the atmosphere upon placing a new bottle of wine on the first reservoir.
