Abstract
A cold beverage dispensing apparatus is powerable by compressed gas and has a thermally insulated cabinet having a cooling chamber containing a source of compressed gas and a water reservoir and a normally non-pressurized syrup pump fluidly connectible to a non-pressurized syrup tank in the chamber, a dispensing nozzle and a manual actuator are on the outside of the cabinet, a pneumatic power valve is operable to connect the gas source to the pump and expel syrup to the nozzle, a pneumatic water valve servo is connected to all of the power valves and the opening of any power valve will effect operation of the servo and opening of the water valve, the pump is inside of the syrup tank and used propellant gas is vented inside the cabinet, a gas bottle and the syrup tanks are racked on the inside of a cabinet door and the power valves are pneumatically connected in series between the gas source and the water reservoir. A method of dispensing cold beverage includes the steps of cooling water and syrup to just above freezing, pressurizing the water, transferring non-pressurized syrup under gravity into a non-pressurized syrup pump and concurrently dispensing water and syrup by opening a …
