Post-mix beverage dispenser with nozzle

Abstract

A post-mix beverage dispensing system has a structure for flushing the dispensing valve and its nozzle of syrup using diluent water from the water supply; the dispensing valve has a nozzle, syrup and water valves and an actuator for the syrup and water valves, a mounting block for the dispensing valve has water and syrup ports with inlets and outlets and normally closed disconnect valves in the outlet enabling removal of the dispensing valve from the block, a flush connector goes across the bottom of the block and is fluidly connected into the water and syrup ports, a normally closed flush valve is in the connector and has an external pushbutton actuator for opening the valve for connecting the water port to the syrup port to flush the syrup port disconnect valve, flow control, syrup valve and nozzle with water, and there is structure to prevent flow of flush water into the syrup supply line. A method of flushing a post-mix valve has the steps of connecting the water line to the syrup line and flushing the syrup valve and nozzle with water from the beverage water supply. An alternative flush valve has structure for neutralizing the syrup pressure so that syrup pressure cannot open the flush valve if and when water pressure drops, and a lever type flush actuator behind the dispensing actuator lever enables easy flushing by squeezing the two levers together with the thumb and finger of one hand.
