<p>A post mix beverage dispensing nozzle (10) includes a housing (11) which contains a diffuser (12). The nozzle connects to a dispensing valve (13) for dispensing a viscous beverage syrup that must be mixed with a mixing fluid, such as water, before dispensing. The diffuser comprises a plurality of interconnected plates (22-29) with the top plate (22) contacting the beverage syrup entering the nozzle to direct the beverage syrup radially outward in a thin sheet. As the beverage syrup expands radially outward past the surface of the top plate, the mixing fluid shears the beverage syrup and forces it to cascade down the remaining plates of the diffuser. The cascading effect created by the remaining plates results in vigorous mixing which produces a dispensed beverage having the desired mix ratio between mixing fluid and beverage syrup.</p> |
